The major responsibilities of the National Marine Fisheries Service (NMFS) are to monitor and assess the abundance and

geographic distribution of fishery resources, to understand and predict fluctuations in the quantity and distribution of these

resources, and to establish levels for optimum use of the resources. NMFS is also charged with the development and implementation of policies for managing national fishing grounds, development and enforcement of domestic fisheries regulations,

surveillance of foreign fishing off United States coastal waters, and the development and enforcement of international fishery

agreements and policies. NMFS also assists the fishing industry through marketing service and economic analysis programs,

and mortgage insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics on various phases of the

industry.

The NOAA Technical Report NMFS series was established in 1983 to replace two subcategories of the Technical Reports

series: "Special Scientific Report-Fisheries" and "Circular." The series contains the following types of reports: Scientific

investigations that document long-term continuing programs of NMFS, intensive scientific reports on studies of restricted

scope, papers on applied fishery problems, technical reports of general interest intended to aid conservation and management,

reports that review in considerable detail and at a high technical level certain broad areas of research, and technical papers

originating in economics studies and from management investigations.

ABSTRACT

Species composition, biomass, density, and diversity of bentblc invertebrates from six bard-bottom areas

were evaluated. Seasonal collections using a dredge, trawl, and suction and grab samplers yielded 432, 525, and

845 taxa, respectively. Based on collections wltb tbe diCCerent gear types, species composition of invertebrates

was found to cbange batbymetrically. Inner· and mlddle-sbelf sites were more similar to eacb otber In terms of

invertebrate species composition tban tbey were to outer-sbelf sites, regardless ofseason. Sites on tbe Inner and

outer sbelf were grouped according to latitude; bowever, results suggest tbat deptb Is apparently a more important determinant of Invertebrate species composition tban eltber season or latitude. Sponges generally

dominated dredge and trawl collections In terms of biomass. Generally, cnldarlans, bryozoans, and sponges

dominated at sites In terms of number of taxa collected.

Tbe most abundant smaUer macrofauna collected In suction and grab samples were polycbaetes, ampbl.

pods, and mollusks. Densities of tbe numerically dominant species cbanged botb seasonally and batbymetrlcally,

witb very few of tbese species restricted to a specific batbymetrlc zone.

Tbe blgb diversity of invertebrates from bard·bottom sites Is attributed to tbe large number of rare species.

No consistent seasonal cbanges in diversity or number of species were noted for individual stations or deptb

zones. In addition, n' and Its components sbowed no definite patterns related to deptb or latitude. However,

more species were collected at mlddle-sbelfsites tban at Inner- or outer·sbelfsites, wbicb may be related to more

stable bottom temperature or greater babltat complexity In tbat area.

INTRODUCTION

Although other studies have provided species lists of invertebrates from hard-bottom areas [see Continental Shelf Associates

(1979) for literature review], Wenner et al. (1983) provided the

first detailed information on structure of hard-bottom invertebrate

communities in the South Atlantic Bight. Results indicated that

the invertebrate fauna of these areas was more diverse than the

surrounding sand biotope, Species composition was apparently

related more to station depth than to season, although species

associations did vary between winter and summer. Because sampling during their study was limited to only two seasons, it was not

possible to determine seasonal trends in community composition,

structure, and biomass which might be occurring over an annual

cycle.

This paper presents results from a second-year study of invertebrates associated with hard-bottom habitats anq focuses on

seasonal as well as bathymetric changes in community

parameters. Comparisons with results from the initial study of

hard-bottom sites by Wenner et al. (1983) provide additional

information on annual variations in the epibenthic invertebrate

community.

MATERIALS AND METHODS

Collection of Samples

Two study sites were selected between lat. 31 °24' and 32°49'N

from each of three bathymetric zones: Inner shelf (ISO I, 17-18 m;

IS02, 17-22 m), middle shelf (MS02, 23-29 m; MS06, 32-36 m),

and outer shelf (OSOI, 59-67 m; OS06, 46-69 m) (Fig. 1). Four of

the sites (ISOl, IS02, MS02, OSOI) were previously assessed during the initial study (Wenner et al. 1983). All sites were sampled

quarterly during 1981 as follows: Winter (25 February to 17

March), spring (26 April to 28 May), summer (25 July to 13

August), and fall (6 October to 16 November).

Prior to sampling for invertebrates, hydrographic profiles of

temperature, salinity, and dissolved oxygen were obtained at each

site by Niskin bottles with reversing thermometers.

Qualitative samples of large and encrusting macroinvertebrates

were taken quarterly with a heavy duty Cerame-Vivas dredge

(Duke University Marine Laboratory 1968) having a mouth opening 90 cm x 37 cm and maximum mesh opening 40 mm x 30

mm. Two replicate dredge tows were attempted at each station

with a total of 43 actually completed. Tow length was standardized to approximately 0.1 km using 10ran-C positioning.

Additional qualitative collections of large macroinvertebrates

were obtained as incidental catch by a trawl (12 m headrope, 16

m footrope, 12.8 m vertical height) equipped with steel doors and

rubber rollers. Six replicate tows (three day and three night) were

attempted quarterly at all sites except station OS06, where high

bottom relief prevented use of the trawl. Altogether, 119 trawl

tows were completed. Trawl tows were standardized to a distance

of about 1 km.
Figure I.-Location of bard-bottom stations sampled during 1981.

Invertebrates collected by dredge and trawl were sorted into the

following major taxonomic groups for wet-weight estimates:

Porifera, Hydrozoa, Scleractinia!Octocorallia, Mollusca,

Decapoda, Echinodennata, Ascidiacea, and other miscellaneous

invertebrates. Encrusting organisms which could not easily be

removed from rocks were not weighed. Representative specimens

of each species were preserved in 10% buffered seawater Formalin and transferred to 70% isopropanol prior to identification.

Quantitative samples of smaller benthic invertebrates not adequately sampled by dredge and trawl were obtained at inner- and

middle-shelf sites by scuba divers using an airlift suction sampling

device similar to that described by Chess (1979). Divers obtained

five replicate samples at each station from a suitable area chosen

to avoid large patches of sand commonly found at the sites. A disc

with five equally spaced radial marks was dropped to the bottom

and a 3 m line, fastened to the center of the disc, was then used to

place five open-ended quadrat boxes (0.1 m2 , 10 cm walls) equidistantly around the disc. Exact positioning of the quadrat boxes

was accomplished by randomly selecting one of nine possible

quadrat areas from a larger grid frame attached to the 3 m line.

Fauna within the quadrat was sampled by scraping the area while

simultaneously sucking with the airlift suction device to a depth of

10 cm or until rocky substrate was encountered. Suction was applied until all sediment within a quadrat was removed to the

designated depth. All suction samples were collected in 1.0 mm

mesh bags and brought to the surface for preservation. On deck,

each sample was narcotized with 10% magnesium chloride and

preserved in a 10% seawater-Fonnalin solution.

At each outer-shelf station, where water depth precluded the

use of a diver-operated suction device, five quantitative 0.1 m2

samples were attempted with a Smith-McIntyre grab. Only 33

samples were collected due to ineffective sampling of the grab on

hard substrates. After retrieval, each sample was placed on a 1.0

mm sieve and washed to remove the finer sediment prior to

preservation in 10% buffered seawater Fonnalin. Macroinvertebrates collected by suction and grab samplers were identified and

counted, except for encrusting fauna which were not easily quantified by counting (e.g., hydroids and colonial corals).

Data Analysis

Community diversity was estimated by the Shannon index (It)

(Pielou 1975) in conjunction with species richness (SR) (Margalef

1958), and evenness (J) (Pielou 1975). These measures were

computed on data from pooled replicates taken with suction or

grab samplers at each station, since pooling the replicates provided a larger sample size and a more representative estimate of

community diversity at a site. The degree of dominance at a station was quantified with the dominance index (01) (McNaughton

1967). For qualitative collections by dredge and trawl, diversity

was evaluated by comparing the number of species (s) among stations. The Kruskal-Wallis one-way analysis by ranks (Siegel

1956) was used to detennine whether s differed significantly between stations or seasons.

Cluster analysis was used to detennine patterns of similarity

among stations (pooled replicated collections) and among species

using qualitative binary data (i.e., species presence or absence) for

dredge and trawl samples, and quantitative abundance data for

suction and grab samples. Due to the large number of species in

collections made by the various sampling devices, it was

necessary to reduce data sets which contained> 200 species prior

to cluster analysis in order to remain within the computational

limits of available computer programs. Data sets were reduced by

both elimination of species which were infrequently collected and

elimination of taxa having undetennined or questionable identity.

The elimination of these taxa from our data sets was justifiable

because "rare" species usually do not have definable distribution

patterns and can confuse interpretation of cluster analysis. Data

sets subjected to cluster analysis were reduced to include only

those species represented in 5 or more dredge collections, 9 or

more trawl collections, and 12 or more suction and grab collections.

Species and collections were classified using flexible sorting

(Lance and Williams 1967) with a cluster intensity coefficient (fJ)

of -0.25. The Jaccard similarity coefficient (Clifford and

Stephenson 1975) was used with presence-absence data collected

by dredge and trawl. Species abundance data collected by suction

and grab were transfonned using log10 (x + 1) and clustered using

the Bray-Curtis measure of similarity (Bray and Curtis 1957).

Since attribute values covered a wide range, a strong transfonnation was used to reduce the sensitivity of the Bray-Curtis measure

to larger values (Clifford and Stephenson 1975).

Subsequent to cluster analysis, species and station groups were

chosen using a variable stopping rule (Boesch 1977). Then nodal

analyses (Williams and Lambert 1961; Lambert and Williams

1962) were employed to describe pooled collections at a station in

tenns of their characteristic species and to describe species groups

resulting from inverse cluster analysis in tenns of their patterns of

occurrence at stations (Boesch 1977). Coincidence of station and
species groups was expressed by graded constancy and fidelity

values, which were used to determine those species that were most

consistelltly collected and most restricted to pooled collections at

a station. The mathematical definitions for constancy and fidelity

are found \n Boesch (1977).

RESULTS AND DISCUSSION

Hydrographic Measurements and Description of

Study Sites

Hydrographic parameters at the hard-bottom sites were similar

to those reported by Wenner et al. (1983). Bottom temperatures

on the inner shelf were more extreme (I 1.7 °-27.3 0c) than those

on the outer shelf (17.0o-23.9°C). Temperatures at middle-shelf

sites were similar to those encountered at outer-shelf sites

(16.0o-23.4°C). Bottom salinity and dissolved oxygen were

generally high at the sites during all seasons, ranging from 34.3 to

36.6% 0 and 3.9-6.4 mVI, respectively.

Television transect videotapes showed that the bottom at station ISO I was smooth, flat, and overlaid by a layer ofsand. Sessile

invertebrates at ISOI were numerous and uniformly covered the

broad expanse of sand-covered hardpan. Station IS02 had a more

irregular bottom than ISOI with numerous rock ledges and discontinuous outcroppings up to 1 m in height. These outcroppings

were distributed throughout areas ofsand and were covered with a

dense assemblage of epifauna, particularly adjacent to the ledges.

Middle-shelf sites were characterized as having moderate relief

ledges, although there were also areas of low rocky relief interspersed with sand. At MSOl, several ledges up to I m in height

were observed, whereas ledges with a vertical drop of nearly 2 m

were observed at MS06. Epifaunal density was usually high on

emergent rock of moderate to high relief at MS06.

Outer-shelf stations, which were located in the vicinity of the

shelf break, wer;e distinctly different from one another with

respect to their bottom topography. Station OSOI was a low relief

hardground with only occasional exposed rock of little relief and

relatively sparce epifaunal density. In contrast, OS06 was a

typical shelf edge reef, with irregular bottom topography characterized by ledges and extensive rock outcropping of moderate to

high relief which were often heavily encrusted with invertebrates.

Large Macrofauna Sampled by Dredge and Trawl

Seasonal collections of epifauna from hard-bottom sites sampled by dredge and trawl yielded 432 and 525 taxa, respectively.

A list of the identified taxa, arranged phylogenetically for each

station and sampling gear, is found in Appendices I and 2. The

Bryozoa (91 taxa), Porifera (89 taxa), and Cnidaria (70 taxa),

dominated dredge collections from all seasons in terms of numbers

of taxa. Porifera (111 taxa) were also well represented in trawl

collections, along with other taxa such as decapod crustaceans (86

taxa), Bryozoa (85 taxa), and Mollusca (85 taxa). Both the present

and previous study (Wenner et al. 1983) of hard-bottom communities have shown that Porifera, Bryozoa, and Cnidaria are the

most diverse taxonomic groups encountered.

The only invertebrate groups whose percent contribution of

species in dredge and trawl collections changed noticeably across

the continental shelf were the Porifera, Cnidaria, and Bryozoa

(Table 1). In terms of number of taxa, sponges were most important at sites on the inner shelf. Their richness diminished at

middle- and outer-shelf sites where cnidarian and bryozoan taxa

dominated. No seasonal trends in percent composition among taxa

were noted.

The number of invertebrate taxa (s) collected at each station by

dredge and trawl did not change significantly between seasons

(Kruskal-Wallis test, P >0.05). These results were consistent with

those reported by Wenner et al. (1983) who found no significant

difference in s between winter and summer sampling periods.

However, in the present study we did find a significant difference

in s between stations sampled (Kruskal-Wallis test, P < 0.01) by

trawl. Although the fewest species were collected at IS01, this is

not necessarily indicative of generally lower richness at inner

shelf stations, nor do these results imply that s is influenced solely

by depth or latitude, since little difference was noted between

numbers of species collected at IS02, middle-shelf sites, and

OS01. Increases (or decreases) in s are probably also influenced

by localized factors at each site such as topographic complexity

and habitat heterogeneity. The extensive hard-bottom area of

ISOI had little vertical relief compared with IS02, which was

characterized by numerous rock ledges supporting dense epifaunal

populations. These rock ledges provide complex microhabitats

which allow many epifaunal species to coexist (Schoener 1974;

Menge and Sutherland 1976). In addition, many sessile species

settle in greater abundance on structurally complex substrata

because there is more surface area to which they can securely attach (Seed 1976; Russ 1980; Dean 1981).

Normal cluster analysis indicated that pooled replicate dredge

and trawl collections were classified into three station groups corresponding to inner-shelf sites (group 1), middle-shelf sites (group

2), and outer-shelf sites (group 3) (Fig. 2). Stations were not

grouped in a manner which would indicate that species composition changed seasonally in a consistent pattern. Even within each

site group, no grouping of stations by season was evident. This

suggests that the qualitative composition of the epifaunal community sampled by dredge and trawl was generally similar

throughout the year. In addition, there was no indication that stations were grouped in accordance with their latitudinal location

on the continental shelf. Comparison with results of normal

cluster analysis from the initial study indicates that depth is apparently a more important determinant of faunal composition

than season or latitude at hard-bottom sites off South Carolina and

Georgia. These results suggest that the epifaunal community of

hard-bottom areas are persistent throughout the year. Osman

(1977) suggested that changes in the composition of epifaunal

invertebrates occur slowly. Growth and reproduction rate of epifauna are reduced during the winter with the result that few new

species are added, but several are lost.

Inverse cluster analysis of the 199 most frequently occurring

species from seasonal dredge collections formed 10 groups (Table

2). Nodal analysis indicated that the three major branches of the

inverse cluster dendrogram represent species assemblages found

primarily at inner-shelf sites, those found across the shelf, and

those found primarily at middle- and outer-shelf sites (Fig. 3).

Species which were most consistently collected at inner-shelf

stations partially comprise groups A, C, and D. However, these

assemblages were not restricted to sites on the inner shelf, as indicated by moderate fidelity values. Species in these groups which

were collected only at inner-shelf sites included the sponges

Homaxinella waltonsmithi and Tedania ignis; the echinoderms

Lytechinus variegatus, Encope michelini, and Luidia alternata; and

the mollusk Pisania tincta. Except for the sponges H. waltonsmithi

and T. ignis, these species are found on a wide variety of bottom

types and are not limited to hard substrates. Although the cluster

hierarchy indicated that group Band C species were most similar

in their occurrence at hard-bottom sites, the nodal diagram illustrates differences in the distribution of species in these two

groups. Species in group B were most constant at station OSO1;

whereas species in group C were most constant at station IS02.

Species in groups E and F were consistently collected at most

sites sampled. Group E species were highly constant at all sites

and included the most ubiquitous species collected. Many of the

species in this group were dominant epifaunal organisms in terms

of their frequency of occurrence at hard-bottom sites across the

shelf. However, because of their ubiquity they were not faithful to

any site group. Species in group F were also fairly ubiquitous but

were more commonly encountered at inner- and middle-shelf

sites.

Species groups G-J were most consistently collected at middleand outer-shelfsites. Group G species displayed high constancy at

stations MS02 and MS06; however, the only species in this group

which was collected exclusively at middle-shelf hard-bottom stations was the bryozoan Schizoporella errata. Group H species also

were common at station MS06 but were most consistently encountered at station OS06. Species groups I and J displayed

highest constancy and fidelity at outer shelf sites; however, only

species in group J were restricted to these locations, as indicated

by their very high fidelity values. Species in groups I and J which

were collected exclusively at outer-shelf sites included the

cnidarians Balanophyllia floridana, Diodogorgia sp., Ellisella sp.,

and Stylatula sp.; the decapod crustaceans Galathea rostrata, Dardanus insignis, and Parthenope fraterculus; the bryozoan Membranipora arborescens; and the echinoderm Astroporpa annulata.

Comparisons of species assemblages identified by cluster and

nodal analyses between the present and the previous study

(Wenner et al. 1983) have shown that several species are most

frequently encountered in one depth zone. Those which typified

inner-shelf hard-bottom sites included the sponges Homaxinella

waltonsmithi, Spheciospongia vesparium, Cliona caribbaea, and

Halichondria bowerbanki; the echinoderms Encope michelini,

Lytechinus variegatus, Ocnus pygmaeus, and Arbacia punctulata;

the bryozoan Membranipora tenuis; and the decapod crustacean

Synalpheus minus. Middle-shelf hard-bottom sites were characterized by the bryozoans Chaperia sp., Aeverrillia setigera,

Schizoporella floridana, Petraliella bisinuata, and Parellisina curvirostris; and the hydroids Thyroscyphus marginatus and Synthecium tubitheca. Species which were consistently collected at

outer-shelf sites during both years of sampling by dredge included

the bryozoans Smittipora levinseni, Stylopoma in/ormata,

Cribrilaria floridana, and Cycloperiella rubra; the hydroids

Dynamensa dalmasi and Filellum serratum; the echinoderm

Astroporpa annulata; and the decapod crustacean Mithrax

acuticornis. Few species assemblages identified by cluster analysis

of dredge samples were restricted to anyone depth zone or hardbottom site. This suggests that few species assemblages, other than

those displaying high fidelity values in nodal diagrams, could be

considered characteristic of a particular depth zone in the South

Atlantic Bight.

Inverse cluster analysis of 184 species from seasonal trawl

collections produced seven groups. Species and site group coincidences were interpreted in terms of nodal constancy and fidelity

(Table 3, Fig. 4). Group A contained species which were characteristic of inner-shelf stations and station MS06. Species in group

B also displayed high constancy for inner-shelf stations; however,

no species in either group were restricted to specific hard-bottom

sites. Only the tunicate Ascidiacea A was collected exclusively at

inner-shelf sites.

Groups C, D, and E were composed of species which were fairly

ubiquitous at hard-bottom sites across the shelf. Species in group

6

C were highly constant at inner- and middle-shelf stations,

whereas those in group D were consistently collected at every

live-bottom site sampled. This group contained many of the most

frequently occurring epifaunal species collected during the study.

Group E contained species which displayed high constancy at stations IS02, MS02, and MS06. Species in group F were highly constant at station MS06, but were not restricted to this station. Those

species in group G were most frequently collected at both middleshelf sites and at the outer-shelf station. As indicated by the inverse dendrogram, species in group H, which were highly constant

at station OSO I, were least similar to other groups in terms of their

distribution. Several species, such as the bryozoans Aplousina

gigantea and Cycloperiella rubra, the octocoralEllisella sp., and the

decapod crustacean Mesopenaeus tropicalis, were collected only at

station OS01.

No species assemblage identified from our study was restricted

to specific hard-bottom sites. However, comparison of species

assemblages from cluster analysis of winter and summer from the

first-year study (Wenner et al. 1983) with seasonal data from the

present study show that the following species formed a consistently recurring assemblage on the inner shelf: The bryozoans

Scrupocellaria regularis and Hippoporina contracta; the

echinoderm Ocnus pygmaeus; and the crustaceans Synalpheus

longicarpus, S. minus, Pilumnus pannosus, Megalobrachium

soriatum, Trachypenaeus constrictus, and Conopea galeata.Other

species, such as the cnidarian Sertularella areyi; the echinoderm

Astroporpa annulata; the sponges Xytopsues griseus and

Sigmadocia caerula; and the decapod crestaceans Mesopenaeus

tropicalis, Sicyonia brevirostris, and Solenocera atlantidis, were

consistently collected during both years at outer-shelf sites. These

findings suggest that there is no sharp bathymetric zonation of

epifaunal species groups in hard-bottom habitats of the South

Atlantic Bight. However, the least similarity in species composition apparently occurs between inner- and outer-shelf sites while

middle-shelf sites represent a transition zone between the other

strata.

Biomass of Larger Macroinvertebrates

Comparisons of total biomass between taxa showed that

Porifera were dominant at all stations during each season, except

at station MS06 in spring, when biomass of Ascidiacea was

highest (Table 4). These results are similar to those reported by

Wenner et al. (1983) who found that Porifera accounted for a

large percentage of the total invertebrate biomass from both the

dredge and trawl collections. In the present study, the seasonal

contribution of Porifera to the total biomass of invertebrates collected by dredge and trawl was as follows: Winter (78%), spring

(59%), summer (67%), and fall (76%). The only taxa other than

sponges and tunicates which formed a significant component of

sample biomass in dredge or trawl collections were anthozoans

and mollusks.

Analysis of variance of logarithmically transformed biomass

values from replicate samples (OS06 excluded) indicated no

significant difference in biomass between seasons for invertebrates collected by dredge or trawl (P > 0.05). Because many of

the large macrofauna sampled by dredge and trawl, such as

sponges, appear to persist throughout the year, major changes in

biomass were not observed. Undoubtedly, our sampling methods

were not refined enough to detect minor seasonal changes in

biomass due to growth or mortality.

Significant differences in biomass were noted between stations

(P < 0.05) for dredge-collected invertebrates, with the greatest

average biomass recorded at stations IS02 (x = 22.3 kg) and ISOI

(x = 13.6 kg). The lowest biomass of invertebrates collected by

dredge occurred at station MS06 (x = 4.9 kg). Low biomass at this

station is probably related to the patchy occurrence of invertebrates. Television transects showed that epifaunal organisms

were sparse over parts of this station, with large expanses of sand

interspersed with patches of live bottom. In addition, some sampling bias may have resulted from limiting dredge tows at MS02

and MS06 to areas of low relief. Since epifaunal growth was most

dense on moderate to high relief ledges and rocks, an underestimation of biomass may have resulted from avoiding these areas.

Biomass values for trawl-collected invertebrates were greatest

at an inner-shelf site, which is consistent with results from the initial study (Wenner et al. 1983). Among stations sampled by trawl

(OS06 excluded), average biomass values were significantly

greater (P < 0.001) at IS02 (x = 35.8 kg), MS02 (x = 23.2 kg),

and ISOI (x = 10.6 kg). The lowest average biomass was recorded

at station OSOl (x = 3.2 kg).

SmaUer Macroinvertebrates Sampled by

Suction and Grab

A total of 845 taxa was collected during seasonal sampling with

suction sampler and grab. A listing of all fauna collected, including their ranks by abundance and density at each station, is

presented in Appendix 3. The phylum Annelida, which was represented by more species than any other group during the initial

study (Wenner et al. 1983), was also the most diverse group in the

present study, where it contained 285 species. Annelids also

dominated collections in terms of numerical abundance, accounting for 72.4% of the total 60,739 invertebrate specimens taken by

suction sampler and grab. Mollusks ranked second among major

taxonomic groups with a total of 251 species; however, mollusks

accounted for only 4.3% of the total number ofinvertebrate specimens and were outranked by amphipods (100 species) which

represented 13.3% of total invertebrate abundance. Other groups

represented in suction and grab collections included decapod

crustaceans (111 species), arthropods other than amphipods and

decapods (49 species), echinoderms (39 species), nemerteans (3

species), and sipunculans (7 species). Many of the taxa collected

by suction and grab represent sand-bottom species which are also

common at the hard-bottom sites, since there is generally a sand

layer covering the rock bottom.

The 10 invertebrate species which numerically outranked

others at the hard-bottom sites during all seasons were the polychaetes Filograna implexa (n = 30,346), Pista palmata (n

1,439), Syllis spongicola (n = 1,358), Spiophanes bombyx (n =

650), Chone americana (n = 543), Malacoceros glutaeus (n =

535), and Exogone dispar (n = 482); and the amphipods

Luconacia incerta (n = 907), Photis sp. (n = 631), and Erichthonius brasiliensis (n = 523). These species accounted for about

62% of all invertebrate specimens caught in suction and grab

samples.

Densities of the 10 numerically dominant species changed

seasonally and bathymetrically. In winter, the amphipods

Luconacia incerta, Photis sp., and Erichthonius brasiliensis were

important at inner-shelf sites (Table 5). Their densities at these

sites decreased in spring; and during the rest of the year <5 individuals/0.1 m2 were collected. The density of F. implexa was

high in fall, when approximately 182 individuals/O.I m2 were collected at IS01. Another species whose density was highest in fall

on the inner shelf was the polychaete Syllis spongicola. However,

neither of these species was consistently abundant at both innershelf sites.

Filograna implexa was the dominant species at middle-shelf

sites (Table 6). The maximum density of F. implexa occurred in

fall at MS06 when 4,155 individuals/O.l m2 were collected (Table

5). The high densities of F. implexa which were observed at midshelf sites did not occur on the outer shelf (Table 6). Species

which were important at these deeper sites were the polychaetes

Pista palmata and Spiophanes bombyx, with the highest densities

for both occurring in spring.

Comparisons with results presented by Wenner et aI. (1983)

confirm that F. implexa is the numerically dominant invertebrate

at middle-shelf sites. However, its importance at outer-shelf sites

was considerably diminished during the second year of sampling

when numbers of Pista palmata exceeded those of other species

collected. Filograna implexa was also important on the inner shelf,

but densities did not approach those noted in previous collections

from these sites.

Other investigators (Frankenberg 1971; Frankenberg and

Leiper 1977; Tenore 1978) have noted that density variation over

space and time is typical of numerically dominant species in softbottom communities on the continental shelf off Georgia. Wenner

et al. (1983) speculated that variable abundances of benthic

invertebrates could be influenced by 1) differentially successful

and sequential recruitment by larvae of various species; 2) predation, especially by fishes; and 3) differing microhabitats within

and between sites.

Predation could influence the communities in this study since it

has been found to be a major factor affecting benthic populations

in soft- and hard-bottom communities of the intertidal zone

(Paine 1966; Peterson 1977). However, studies on the effects of

predation on the continental shelf are limited and largely conjectural. Frankenberg and Leiper (1977) hypothesized that fishes

remove large numbers of small crustaceans, such as cumaceans

and amphipods, from benthic assemblages. Predation on benthos

can also be expected to alter species composition, resulting in

greater abundance of those species having higher intrinsic rates of

population increase (Slobodkin 1961); and, furthermore, a selective preference of predators for soft forms such as crustaceans or

polychaetes may shift species composition toward forms with

exoskeletons which are more resistant to predation (e.g., mollusks)

(Richards 1963). Examination of stomach contents of 10 species

of fishes known to inhabit live-bottom areas showed that amphipods, polychaetes, and decapods were most heavily preyed upon,

including the numerically dominant species Exogone dispar and

Erichthonius brasiliensis (G. Sedberry).

Table 7.-Seasonal community structure values [num"".. orindividuals, number

or species, diversity (H'), evenness (J'), rlcbness (SR), and dominance Index

(DI)) ror pooled repUcate samples or Invertebrates at eacb station.

Much of the variability in populations of infaunal organisms

can be attributed to our sampling methods which included too few

replicates to accurately determine whether changes in density

were due only to seasonality. In addition, the complex' physiography and diverse substrates of hard-bottom habitats create a

habitat patchiness that could result in either selective settling by

larvae or differential survival of different benthic invertebrate

species. Other physical factors which have been reported to affect

stability (i.e., persistence) of benthic populations are fluctuations

in water temperature (Boesch et a1. 1977) and disturbance of

sediments by storms (McCall 1977). Boesch et a1. (1977) attributed the temporal stability of macrofaunal species on the outer

shelf of the Middle Atlantic Bight to decreasing thermal variation

and reduced effects ofstorms in deeper water. Although upwelling

of colder water does occur on the continental shelf in the South

Atlantic Bight, most of the benthic infaunal species collected by

suction sampler and grab have wide latitudinal ranges and are

eurybathic, extending from the intertidal zone to the continental

slope and beyond. Thus, most should be fairly tolerant of the environmental conditions found at hard-bottom sites on the shelf.

Values of Shannon diversity (II'), evenness (J), richness (SR),

dominance (01), number ofspecies (s), and number of individuals

(n) showed no consistent patterns between depth zones and

seasons (Table 7). During all seasons,It was> 5 bits/individual at

both inner-shelf stations, except ISOI in fall when It was 4.58.

This comparatively low It value reflected an uneven distribution

of individuals among species at ISOI and, consequently, an

elevated dominance index (01) value rather than low SR or s. Low

evenness and high 01 were attributed to large numbers of the colonial polychaete Filograna implexa.

More species were collected at mid-shelf stations than at any

others sampled. Approximately 42 and 48% of all species collected at MS02 and MS06, respectively, were represented by one

or two individuals and are consequently considered rare. Both s

and SR were greatest at mid-shelf stations in winter; however, the

community-structure values were not seasonally consistent between stations. For example, values ofIt were high (> 6) at MS06

during all seasons·except fall when the lowest It value for any station sampled occurred. At MS02, high It values were noted only

in winter and summer. As noted for inner-shelf stations, low It

values were affected by low evenness which reflected strong

dominance by the polychaete F. implexa.

Community-structure values at outer-shelf stations were also

not consistent between stations or seasons. At station OS06, It

and J showed little seasonal variation and indicated that species

were fairly diverse and evenly distributed. The dominance index

also indicated that collections were not num~rically dominated by

one or two species. However, sand SR at OS06 did change with

season, being much lower in fall. At station OSO I, seasonal

changes in It reflected concomitant changes in evenness and

dominance. Thus, although more species and greater SR occurred

at OSOI in spring, It was lower than in any other season at this

station due to numerical dominance by the polychaete Pista

palmata. Most community-structure values at outer-shelf sites

were comparable with those obtained on the inner shelf; however,

the fewest species obtained on the shelf were recorded at OSO 1 in

winter and OS06 in fall. In addition, fewest individuals were collected at outer-shelf stations.

In general, results from the present study are consistent with

those reported in the initial study of hard-bottom habitats (Wenner et a1. 1983). Sampling during both years has shown that rare

species are a conspicuous component of the hard-bottom community and contribute to elevated species richness at all of the

sites sampled. In addition, no cons.istent seasonal changes in

diversity or s (Kruskal-Wallis test, P > 0.05) were noted for stations or depth zones. The low It values which occurred at hardbottom sites sampled in both years of study apparently reflect

localized changes in the population density of a few dominant

species, such as F. implexa, and are probably not indicative of any

seasonality.

Although II' and its components did not show any definite patterns with regard to depth or latitude, the number of species was

found to be significantly different between sites (Kruskal-Wallis

test, P < 0.01). Specifically, more species were collected at midshelf sites, which may be related to more stable bottom temperatures in this area of the shelf (Miller and Richards 1980). In terms

of community structure, these sites were characterized by I) a

large number of species, many of which were rare, and 2) high

numerical dominance by Filograna implexa. In contrast, innershelfsites, which were subject to more extreme temperature variations, generally had fewer species and less dominance than sites

on the middle shelf. Outer-shelf sites are also thermally variable

because of intrusions of colder upwelled water, which

predominantly occurs in fan (Atkinson et a1. 1978). Fewest

species were recorded at outer-shelf sites, and many of those

which occurred were rare. In addition, dominance was relatively

low. These results suggest that fluctuating temperatures at innerand outer-shelf sites may exert some control on community structure at live-bottom sites. However, it is also possible that the

lower richness at outer-shelfsites was due to collection ofsamples

with a grab which does not sample hard substrates as effectively

as the suction device. Although within-reef habitat heterogeneity

is one important factor in determining richness of benthic fauna,

thermal stability is probably also important.

Normal cluster analysis of pooled replicate collections taken

with suction and grab samplers grouped stations according to

depth zones with inner-shelf stations forming group I, middleshelf stations forming group 2, and two outer-shelf sites forming
groups 3 and 4 (Fig. S). The two outer-shelfstation groups constituted a larger agglomeration in the dendrogram which was very

dissimilar in species composition to the inner- and middle-shelf

groups.

None of the stations,were grouped together by season; however,

inner- and outer-shelf sites were grouped according to latitude

with ISOI and OSOI clustering separately from IS02 and OS06,

respectively. Major agglomerations in the dendrogram indicated

bathymetric separation of sites, suggesting that depth is a major

factor influencing species distribution. During the previous study,

quantitative collections of smaller epibenthic and infaunal

organisms were separated according to bathymetric zones during

winter but not during summer, suggesting that the quantitative

composition of the hard-bottom community was much more

homogeneous across the shelf during summer (Wenner et al.

1983). However, based on the present study, we have found no

evidence to suggest consistent seasonal change in community

composition. Similarly, seasonal differences in species

assemblages were not observed by Boesch et al. (1977) in a study

of benthic communities in the Middle Atlantic Bight.

Most species groups delineated by cluster analysis were not

limited in their distribution to one depth zone (Table 8, Fig. 6).

Species in group A were consistently collected at inner- and

middle-shelf sites, whereas those in group B were highly constant

at all sites. Group C species were .also ubiquitous, but displayed

high constancy for middle-shelf stations. The only species in this

group which was collected solely at middle-shelf sites was the

polychaete Ceratonereis sp. A. Species in group D, which were

widely distributed across the shelf, displayed highest constancy at

middle-shelf stations and OSOL Groups E, F, and G were most

consistently collected at inner- and middle-shelf stations but were

not restricted in their distribution to these sites. The tanaidacean

Apseudes sp. A, which occurred in group G, was the only species

which was restricted to inner-shelf sites. Species in group H were

found at all stations but were most frequently encountered at

middle-shelf stations and OS06.

Examination of inverse cluster groups and nodal diagrams from

the initial survey of hard-bottom habitats also revealed that few

species were limited to specific bathymetric zones during both

years of study (Wenner et al. 1983). No species was found to be

highly constant at inner-shelfsites, whereas the polychaete Eunice

jilamentose, the amphipod Megaluropus sp., and the mollusk

Chione grus were most consistently collected at middle-shelf sites

during both years. In addition, the amphipod Erichthonius sp. A,

the polychaete Syllis sp. D, and the echinoderm Genocidaris

maculata were characteristically found at sites sampled on the

outer shelf in both studies. These results indicate that ~any of the

smaller epifaunal and infaunal species comprising benthic

assemblages at hard-bottom sites are relatively ubiquitous across

the shelf, although differences in overall community composition

were observed between depth zones.

CONCLUSIONS

I) A total of 1,307 invertebrate taxa was collected with all sampling devices documenting the diverse nature of offshore hardbottom habitats. Most sites were inhabited by rare species which

were represented by only one or two individuals. Numerical

dominance was limited to the polychaetes Filograna implexa and

Pista palmata which were prevalent at middle- and outer-shelf

sites, respectively.

2) Diversity of hard-bottom sites was generally high during all

seasons. No consistent seasonal changes in diversity were noted

for stations or depth zones throughout the study area. Low If

values were attributable to low evenness caused by high numbers

of species such as Filograna implexa and Pista palmata. Although

If and its components did not show any well defined changes with

depth, season, or latitude, more species were collected at middleshelf sites. This may be related to less variable bottom temperatures in this area of the shelf, coupled with relatively high habitat

complexity due to the frequent occurrence of large sponges and

octocorals, which offer refuge to other benthic invertebrates. The

number of identifiable invertebrate taxa collected at each station

by dredge and trawl did not change significantly between seasons.

Changes in the number of species between stations were attributable to varying degrees of topographic complexity and habitat

heterogeneity.

3) Porifera, Bryozoa, and Cnidaria were the most diverse taxonomic groups collected by dredge and trawl during both years in

which sampling was conducted. Sponges were most diverse at

sites on the inner shelf, but their diversity diminished in dredge

and trawl collections at middle- and outer-shelf sites. Taxa accounting for the greatest number ofspecies in the latter areas were

cnidarians and bryozoans.

4) Comparisons of total biomass between taxa showed that

Porifera were dominant at most stations. No significant difference

in biomass estimates was observed between seasons; however,

bathymetric differences did occur, with biomass being greatest on

the inner shelf for dredge and trawl collections. This may reflect

the more uniform distribution of epifaunal invertebrates at innershelf sites; however, differences between sites may also be caused

by sampling bias since efforts were made not to sample over high

relief ledges on the middle shelf in order to minimize loss of gear.

S) The hard-bottom sites sampled throughout the entire study

area were distinguished from each other primarily by trends in

faunal composition related to depth. No evidence of seasonal

grouping was noted. Epifaunal species censused by dredge and

trawl appeared to be more faithful to particular depth zones than

did benthic organisms sampled by suction sampler and grab.

However, most species assemblages were not restricted to a particular depth zone. Inner- and middle-shelf sites were more

similar in species composition to each other than they were to

outer-shelf sites.

6) The densities of some numerically dominant species collected by suction and grab changed seasonally and bathymetrically.

Such density variations may result from: I) Differentially successful and sequential recruitment among larvae of various species; 2)

predation, especially by marine fishes; and 3) habitat complexity.

Seasonal influences on densities of individual species were not

large enough to cause detectable seasonal changes in overall community structure and composition.
