ECOLOGIA TROFICA DE Mugil curema, M. incilis y M. liza (PISCES: MUGILIDAE) EN LA CIENAGA GRANDE DE SANTA MARTA, CARIBE COLOMBIANO. I. ANALISIS CUALITATIVO Y CUANTITATIVO
Authors: Osorio Dualiby David
Published: October 2017

A comparative study has been carried out considering qualitative and quantitative aspects of the stomach contents ofMugil curema, M. inci/is and M. liza in the Ciénaga Grande de Santa Marta. The percentages of meiobenthic invertebrates in the stomach contents of M. inci/is and M. liza was high in the low salinity period, and decreased with the increase in salinity, when M. curema appeared in the Ciénaga. This species has basically vegetarian diet, eating mainly benthic diatoms; M. liza showed a detritic diet though markedly influenced by accompaning bottom meiofauna and M. incilis the most balanced diet compared to that of the other spe- * cies. Mean particle size found in theÿtomach contents were 163 nm in M. curema, 229 nm in M. incilis and 401xnm in M. liza, thus confirming a selective character in its ingestion.
RESIDUOS DE PLAGUICIDAS ORGANOCLORADOS EN SEDIMENTOS DE LA CIENAGA GRANDE DE SANTA MARTA (CARIBE COLOMBIANO)
Authors: Ramírez T. Gustavo
Published: October 2017

Organochlorine pesticides residues viere detected and measured by gas liquid chromatography from surface sediments of the coastel lagoon Ciénaga Grande de Santa Marta (Colombian Caribbean). The following concentrations were found: 0.40-44.2 for lindane, 1.97-28.2 for heptachlor, 0.17-1.07 for aldrine, 0.19-1.91 for dieldrine, 0.0-0.08 for pp'DDT, and 38-266 for total nonidentified residues, all in parts per billion. Levels of all these pesticides are lower than those found in other coastal areas but the results evidence an accumulation process, and the data provide a baseline for future measurements of this contaminants.
CONDICION BACTERIOLOGICA DE LAS OSTRA DEL MANGLAR (Crassostrea rhizophorae Guilding) EN LA CIENAGA GRANDE DE SANTA MARTA, CARIBE COLOMBIANO
Authors: Escobar Nieves Alfonso
Published: October 2017

Between June 1985 and March 1986 the bacteriological condition of 20 samples of the mangrove oyster (Crassostrea rhizophorae) from two growing areas located in the Ciénaga Grande de Santa Marta was monitored; one of the areas was next to a village and the other far away any human concentration. In both locations the levels of faecal pollution present in the water and in the oysters usually surpasse the safety levels determined by international regulations, being a high potential risk for human health. The unsatisfactory condition of the bivalves comes from the steady flow of sewages produced in the lacustrine villages and in the basin as a whole.

In orden to inventory the species of Cirripedia occuring from the Ciénaga Grande de Santa Marta to Nenguange Bay in the Tayrona National Park, specimens of this group of crustaceans were periodically collected in 1985 and 1986. To date eight species have been reported in the Colombian Caribbean, wich are distributed from Cartagena to Guajira. Among the 14 species reported in this work a Rhizocephala, Loxothylacus texanus lives as parasite of crabs of the genus Callinectes; a Lepadomorpha Oco/asmis muelleri, lives epibionthic on the gills of C. sapidus, and also 12 free living Balanomorpha, are included. The first two species and seven belonging to the Balanomorpha are new records for the Colombian Caribbean, -then rising the number ot reported species to 17.
ALTAS TEMPERATURAS ESTACIONALES DEL AGUA COMO CONDICION DISTURBADORA DE LAS MACROALGAS DEL PARQUE NACIONAL TAIRONA, CARIBE COLOMBIANO: UNA HIPOTESIS
Authors: Bula Meyer Germán
Published: October 2017

Based on field observations and on measurements of temperature, salinity, nutrients and water transparency and movement, each one of these factors is analyzed to try to find out which is most important in controlling growth and productivity of macroalgae in Tairona National Park, Caribbean coast of Colombia. It is hypothesized that temperature is the key factor regulaing these physiological aspects of the Park macroalgae. Its increase to above 26°C as a result of the upwelling decline and of other oceanographic-meteorological phenomena, produces the disturbance (biomass removal) to macroalgae, that is observed annually {wet seasons).
CARACTERIZACION ECOLOGICA DE LA SALINA ARTIFICIAL POZOS COLORADOS, CARIBE COLOMBIANO
Authors: Mancera Pineda José Ernesto
Published: October 2017

An ecological study of Pozos Colorados marine brine was carried out between January an August 1987. Although the two sampled stations were greatly different to each other in genera the dynamics of the ecosystem were apparently controlled by salinity, which varied between 7 and 341 °/oo; its increase, accompanied by a decrease of the water level, possibly generated temperature increament and a decrease of the dissolved oxygen, ranging between 26,3 an 41 °C for the first and between 0 and 5,4 mg/l for the latter. Although the average pH wa neutral (7,5), this reductive environment, also characterized by the abundance of organi matter, ocassionaily generated a slight acidity (6,7). The net primary production was negative i most cases, as a result of an intense respiratory activity. Therefore, the system behaved a heterotrophic, using organic matter as subsidiary energy. The species dynamics was possibl determined by rain and ionic change relations, showing a succesion dominated initially b benthic cyanophites and Dunaliella viridis; an increase in salinity was followed by the appear ance of Dunaliella salina, which dominated in high salinities, before the total dominance of red and pink bacteria began.

EVALUACION DE LA CONTAMINACION EN LOS SEDIMENTOS DE LA BAHIA DE CIENFUEGOS, CUBA
Authors: Ablanedo Nora , González Humberto , Campos Isabel , Torres Ibis
Published: October 2017

Surface sediment samples were taken during two sampling campaigns in Cienfuegos bay (Cuba). The composition of meiobenthic communities, heavy metals and organic matter (carbón and nitrogen) contents were determined in order to assess the influence of anthropogenic sources in the pollution levels of this system. The results show the terrigenous origin of the sediments from different zones of the bay, which are chacacterized for high organic contents, features of decomposition and unstableness, and low number of taxonomic meiobenthic groups. The lowest meiobenthic densities simultaneously with the highest lead contents, were detected in the proximities of discharge points of urban and/or industrial waste waters.
MACROINVERTEBRADOS COLONIZADORES DE RAICES DE RHIZOPHORA MANGLE EN LA BAHIA DE CHENGUE, CARIBE COLOMBIANO
Authors: Reyes Rosaiba , Campos Néstor Hernando
Published: October 2017

In order to study the colonization of macroinvertebrates on the Rhizophora mangle roots, a short term in situ experimet was conducted between March and December 1989, at Bahía de Chengue, using mangrove stick as substrate and comparing their macroinvertebrate composition to the fauna associated to the mangrove roots. Most of the colonizing species were also associated to the roots; 80 species as a total appeared as colonizers: 35 crustaceans, 15 molluscs, 11 annelids, 10 cnidarians, 4 briozoan, 3 sponges and 2 chordates; 2002 specimens were counted, most of them (1757) crustaceans. The rainy season seems to favor colonization, since the highest values of diversity were measured then. Closeness to other habitats is a determinant factor for the arrive of organisms; this is shown by the similarity between the fauna associated to the mangrove roots and that colonizing the sticks in the lagoon, and the lower affinity between the roots,s fauna and that colonizing the sticks directly exposed to the sea.

RECRUITMENT PATTERNS OF SESSILE INVERTEBRATES ONTO FOULING PLATES IN THE BAY OF SANTA MARTA, COLOMBIAN CARIBBEAN
Authors: Garcia Camilo B. , Salzwedel Horst
Published: October 2017

Recruitment of sessile invertebrates onto fouling plates immersed for consecutive two-week periods during one year was found to correlate with the local climatic regime. For selected species was found that they recruited at significantly higher levels in certain local climatic periods, but that these periods are not necessarily the same for the different species. A conceptual model is presented in which the recruitment process is divided in a pre-settlement and a post-settlement phase. The model attempts to predict under which combination of global circumstances periods of increased recruitment are to be expected. Application of the model to the data at hand highlights where the research needs for the future are.
BLANQUEAMIENTO CORALINO DE 1990 EN EL PARQUE NACIONAL NATURAL CORALES DEL ROSARIO (CARIBE, COLOMBIANO
Authors: Solano Oscar David , Navas Suarez Gabriel , Moreno Forero Silvia K.
Published: October 2017

At the beginning of June 1990 a coral-bleaching event was detected in the Islas del Rosario reefs, Colombian Caribbean. A preliminary survey of the Isla Grande northern barrier, and of the Caño Ratón and Isla Pavitos south reefs slopes resulted in a list of 19 affected species, which includes scleractinians, zoantideans and milleporins. Bleached colonies accounted for less than 10% of the total observed. The species most affected were Montastrea annularis and Porites astreoides. The recovery process was followed during a five month period in 20 Montastrea annularis, 3 Acropora palmata and 3 Acropora cervicornis colonies . The bleached patches (injuries) of each colony were meassured, demarked with steel nails and their evolution monitored at monthly intervals. Total mortality was observed in 52% of the injures, incomplete recovery in 40%, and no apparent change in the remaining 8% of the colonies. The coral- bleaching event was coincident with an unusual rise in water temperature (31°C to 32°C) between May and June 1990. As the high temperatures lasted until October of the same year (>30°C), these arÿpressumed to be the main cause of the bleaching phenomenon. The possible role of light as a concomitant factor is-also discussed.

LA MALACOFAUNA DE LA ZONA COSTERA DE SANTA MARTA Y PARQUE NACIONAL NATURAL TAYRONA, CARIBE COLOMBIANO
Authors: Díaz Juan Manuel
Published: October 2017

Based on intesive collectings and published informations an inventory of molluscan species known from the Santa Marta - Tayrona National Natural Park coastal area was performed, including data on substrate and depth preferences of each species. Of a total of 727 species, 485 are gastropods, 214 bivalves, 13 polyplacophorans, 10 scaphopods, and 5 cephalopods. Most species occur in sandy bottoms with seagrass and in rock-rubble zones in shallow water. The high number of species occurring in this region can be explained by the availability of different habitat types and der s in a reduced area and through historic-biogeographic features of this region.
DETERMINACION COMPARATIVA DE LA PRODUCCION PRIMARIA CON LAS TECNICAS DE 14C Y 02 EN AGUAS SALOBRES CON DIFERENTES GRADOS DE EUTROFICACION
Authors: Gocke Klaus , Hernández J. Carlos A.
Published: October 2017

The primary productivity of phytoplankton was determined in the mesotrophic Kiel Bight (KB), the eutrophic Kiel Fjord (KF) and the hypertrophic Schlei Fjord using the 14C-technique and the 0 2 -method. Results of these measurements were compared. These brackish areas of the Western-most part of the Baltic Sea differ markedly in primary productivity (PP). If the depth of maximum productivity alone is considered, the PP, on a volumetric basis, of the Schlei was 9 times higher than in the Kiel Fjord and more than 40 times that of the Kiel Bight. On an area basis the differences were much smaller since the compensation depth in the Schlei was found at no more than 0.8 m, whereas in the Kiel Bight it was 5.5 m and 5.2 m in the Kiel Fjord. In agreement with theoretical considerations, the PP determined with the 1*C-technique (1*C-PP) was larger than the net productivity (NP) and smaller than the gross productivity (GP), both determined with the 0 2-method using a photosynthetic quotient of 1.2. On average, in the Kiel Fjord the NP was 9 % smaller and the GP 36 % larger than the 14C-PP. In the Kiel Bight the NP was 40 % smaller and the GP 72 % larger. However, the relation NP<14CPP<GP was found only in the Kiel Bight and - Fjord, whereas in the polyproductive Schlei the 14C-PP was larger than both the NP and GP (32 % larger than the NP and 7 % larger than the GP). This deviation from theoretical values may be due, in part, to a senescent phytoplankton, which may have had a PQ smaller than 1.2.
CLAVE GRAFICA PARA LA IDENTIFICACION DE FAMILIAS Y GENEROS DE ANFIPODOS DEL SUBORDEN GAMMARIDEA DEL ATLANTICO OCCIDENTAL TROPICAL
Authors: Ortiz Manuel
Published: October 2017

The study of amphipod crustaceans has recently increased significantly, mostly because of their great ecological importance. Those of the tropical western Atlantic, have not been an exception. The study of this group is so complex that families, genera, or species, are rarely included in ecological studies of the marine benthos of this area. The pictorial key presented herein is designed to facilitate the identification of the 30 families and 137 genera of amphipods of the Suborder Gammaridea (excluding fresh-water forms) from the tropical western Atlantic. There is no precedent in amphipod literature of such a key, at least to generic level.

Authors: Sánchez M. Juan Armando
Published: October 2017

Through SCUBA and skin diving various shallow water ecosystems (rocky shores, soft bottoms and coral reefs, 0-30 m deep) were surveyed to collect telestaceans and penatulaceans octocorals; the areas considered were Cartagena, the Rosario islands, Tierra Bomba island, Barú island, San Bernardo islands, Bushnell and Salmedina banks, Capurgana and Zapzurro harbours (8°20,-10°45, N; 75°50,-77°251 W), the Santa Marta area (11°14,50" N; 74°15, W) y and the Guajira (11 °56,58" N; 72°16'18" W), Colombian Caribbean. Stylatula diadema Bayer (Virgulariidae: Pennatulacea) is first recorded for the Caribbean sea and has been found inhabiting soft sand bottoms between 25 and 30 m, at the outer end of Cartagena Bay and the Mangles Bank in San Bernardo islands. The geographic distribution of Carijoa riisei (Duchassaing y Michelotti) (Telestidae: Telestacea) was widen from the Caribbean and Colombia, it has been found in a broad bathymetric range (0.5-30 m) in all the habitats surveyed. Few records of telestaceans and pennatulaceans in this region, as in the rest of the Caribbean, suggest that the octocorallian fauna is mostly represented by gorgonians than by other orders, and shows an inverse relationship with the Indopacific fauna, where the alcyonaceans are the dominant order.

ASPECTOS BIOLOGICOS Y ECOLOGICOS DE MYTILOPSIS SALLEI (RECLUZ1849) (BIVALVIA: DREISSENIDAE) EN BANCOS DE OSTRA DE LA CIENAGA GRANDE DE SANTA MARTA, CARIBE COLOMBIANO
Authors: Puyana Mónica
Published: October 2017

Mytilopsis sallei is a widely distributed species living on hard substrata in the Ciénaga Grande de Santa Marta, where it is particularly abundant on mangrove oyster (Crassostrea rhizophorae) reefs reaching densities of 5000 individuals/m2 . Even though it has wide salinity and temperature tolerances, it prefers those places such as mouths of rivers, where fresh-water supply is constant. It can also withstand turbid waters with a high sediment load. There is no competition between M.sallei and the oyster C. rhizophorae, even in heavily-exploited reefs, because of the environmental preferences of each species and the high productivity of Ciénaga's waters assuring a constant food offer for filtering species. M. sallei has separate sexes; males dominate the population. Ripe individuals are found all year-long, but two periods per year of increased reproductive activity and settlement occur, associated to drastic salinity changes: a major one from October to November {rainy season) and a second of lesser importance from March to April (dry season). Juveniles grow steadily; as they attain greater size growth is minimal. Growth and development of these populations seem to be controlled by the influx of fresh water, the high predation rates and relatively low availability of hard substrata.
BENTHIC COMMUNITIES AND GEOMORPHOLOGY OF THE TESORO ISLAND CORAL REEF, COLOMBIAN CARIBBEAN
Authors: Sánchez M. Juan Armando
Published: October 2017

The benthic communities distribution in Tesoro Island (Colombian Caribbean) coral reef was determined by cartography of reef morphology and functional groups from aerial photographstheodolite triangularon, and bottom transects over depths ranging from Oto 30 m. Tesoro Island is a sand cay reef developed over an emerged reef platform whose basal cone possibly originated by mud diapirism on the continental shelf. The benthic communities are distributed as subzones of the geomorphologic units. The reef crest lies along the breaker zone, formed by Millepora spp. buttresses covered on their tops by Palythoa spp. and seawardly by a turf of Dictyota spp. The rear reef (varying from 0.5-1.5 m in depth) is composed of pavement and grooves with live Pontes pontes and P. astreoides. The foré-reef terrace (2 to 9 m in depth) shows a low relief spur and grooves, composed of Acropora pa/mata skeletons on the windward side and A. cervicornis on the leeward side; sandy accumulations with dense and tall colonies of the gorgonaceans Pseudopterogorgia spp. are also appreciated. In the sandy reef platform there are monospecific patches of Montastraea annularis, P. pontes, M. faveolata, dead Acropora cervicornis and wide sandy zoneswhere patches of Halimedamonile are found. The slope edge, (depths ranging between 7 to >30m) shows mixed corals and gorgonaceans, at the drop-off, laminar corals, especially Montastraea franksiand Agaricia spp., jointly with other deep water organisms such as ellisellid gorgonaceans and antipatharians are found. The benthic communities distribution is influenced by reef geomorphology, wave energy diffraction and the past mass mortality of Acropora.

Authors: García U. Rocío Del Pilar , Alvarado Ch. Elvira M. , Acosta M. Alberto
Published: October 2017

The growth rate in ten months (September 1992 - july 1993) for 30 colonies of Acropora palmata along the northern zone of the Corales del Rosario national natural park, Colombian Caribbean, was determined. Three measuring techniques were used: by hand, by staining with alizarin red, and from growth bands by X ray photography. The annual growth estimate for the species in the Park was 5.2 ± 1.3 cm and was found inversely correlated to the size of the colony (lenght, width and height). The growth presented a spatial variation. The smallest growth was found at Caleta Island and the largest at Caribaru Island. The maximum growth rate was observed in the dry season (December-February). No significant differences were found between measurement by hand and by alizarin red. The X-ray technique showed that Acropora palmata does not present discernible annual growth bands.

A punctual characterization of the soft-bottom macrobenthos was conducted on the continental shelf between Dibulla and Rio Palomino (Colombia). A net of 10 sample sites, 4 van Venn grabs per site, placed in deeps between 6 and 21.5 m, was sampled for this purpose. The results include 75% of the collected organisms, of which 69% were polychaeta and 6% mollusks. Analysis were performed at family level, in order to identify assemblages, a classification analysis between sample sites was performed and the groups there were confronted with the picture obtained from a non metric multidimensional scaling (NMDS). For each assemblage abundance, number of families, family dominance and diversity (K-dominance) were determined. By means of ABC curves the disturbance status of the assemblages was assessed. Finally, the pattern of distribution was related with water column depth and grain size of the sediments by means of the BIOENV technique. Results showed two assemblages called "Cossuridae" and "Lumbrineridae" on the basis of the polychaeta families that characterize them. The "Cossuridae" assemblage occurs in silt sediments offshore. It was the most diverse and showed the highest biomass levels. The Lumbrineridae assemblage occurs in fine sand sediments and shallow waters. The ABC curves analysis suggests that both assemblages are disturbed by natural causes since there is no human activity in the area. Water depth and fine sand were the environmental variables with the highest explanatory power in relation to the spatial distribution of the assemblages.
NOTAS SOBRE LOS PECES DE LA FAMILIA SCORPAENIDAE (PISCES: SCORPAENIFORMES) DEL CARIBE CONTINENTAL COLOMBIANO, INCLUYENDO UN NUEVO REGISTRO
Authors: Acero P. Arturo , Navas S. Gabriel R.
Published: October 2017

Fifteen species of scorpaenids grouped in four genera (Neomerinthe, Pontinus, Scorpaena and Scorpaenodes) are known from the Colombian continental Caribbean. Caribbean scorpaenids may be separated in two ecological groups, those preferably inhabiting soft bottoms (Scorpaena calcarata is the most frequent species in Colombia), and those found in reef areas (Scorpaena plumieri, Scorpaena albifimbria and Scorpaenodes caribbaeus are the most frequent species in Colombia). The record of Pontinus rathbuni is remarkable, because it was unknown from Colombian waters, yet many specimens were collected trawling below 38 m in the Cartagena region. It seems that P. rathbuni and S. calcarata have two populations, one from North America, and another from South America; theses cases would be similar to that of P. longispinis, which includes two populations in the western Atlantic.

HABITOS ALIMENTARIOS DE EPINEPHELUS ACANTHISTIUS Y NOTAS DE OTROS PECES SERRANIDOS CAPTURADOS EN EL PARQUE NACIONAL NATURAL GORGONA, PACIFICO COLOMBIANO
Authors: Gómez C. Giovany O. , Zapata P. Luis A. , Franke A. Rebeca , Ramos T. Gabriel E.
Published: October 2017

From June 1988 to July 1992, in non-continuos samples were caught 2681 fishes of the family Serranidae at the National Natural Park Gorgona; only 161 individuals showed some kind of stomach food content. From these, 95 belong to Epinephelus acanthistius, 26 to E. analogus, 6 to E. itajara, 5 to E. cifuentesi y 29 to Diplectrum eumelum. In general it was observed that these species predate mainly on crustaceans (Squilla panamensis, S. mantoidea, Portunus iridescens), followed by fishes (Cynoponticus coniceps) and by mollusks (Loliginidae), urochordates and some polychaetes. The present work gives up information about the food spectrum of some of the most important commercial species of the family Serranidae in the study area.
COMUNIDADES DE ESPONJAS DE LOS ARRECIFES DEL ARCHIPIÉLAGO SABANA-CAMAGÜEY, CUBA
Authors: Alcolado Pedro M.
Published: October 2017

The research was carried out in order to know the sponge community composition and structure of the Archipelago Sabana-Camagüey, and to assay their use as indicators of the environmental severity and predictability, as well as of the most important stressors of this territory.  For this purpose, sampling was done at stations located in 10 reef transects (between 10 and 20 m deep). Species which occurred more frequently with numerical dominance are typical of environments submitted to strong sedimentation and turbulence, which suggests that these environmental stressors and light are the main determinants of sponge community structure and composition in the studied reefs. The development of dense algal mats is also determinant in shallow stations. Species heterogeneity and species richness, and density tended to be higher toward deeper stations, which indicates an increase of environmental favorability for sponges with depth. Equitability tended to be more homogeneous across the studied depth range. Its values were generally high, which suggests relatively constant environments for sponges. Heterogeneity index was more frequently influenced by equitabiliy than by  species richness. For that reason, a greater influence of environmental stability than environmental favorability on the high values of this index in the studied reefs is suggested. By means of a meta-analysis process, the position of the values of some indexes within their universe of variation was analyzed. At more than 10 m in depth diversity indexes tended to be relatively higher than in other Cuban reefs. Also by applying meta-analysis, stations were classified within a bidimensional gradient of environmental severity and environmental predictability.   Univariate indexes and the dominant species, complemented with species dependent multivariate methods permit to infer the most important stressors, and environmental severity and predictability.
EVALUACION RAPIDA DE ESTRUCTURA Y SALUD DE LAS FORMACIONES CORALINAS DE LA ISLA DE MALPELO (PACIFICO COLOMBIANO)
Authors: Garzón Ferreira Jaime , Pinzón C. Jorge H.
Published: October 2017

Malpelo, a small rocky offshore island that supports one of the few coral populations in the eastern Pacific, was visited on June 1-5, 1999 with the purpose of evaluating the status of the coral communities. Using rapid visual methods, the cover of major categories of sessile organisms and the health condition of the coral species were assessed at 8 stations between 11 and 31 m depth. “El Arrecife”, which is the largest coral formation in Malpelo, seems to have suffered a 20% reduction of the live coral cover since 1972 when a mean value of 65% was recorded. This decline, which probably was originated by the 1982-83 strong bleaching event that affected widely the American Pacific, is reflected also by the present levels of recent coral mortality: mean of 23% at “El Arrecife”. Nevertheless, live hard corals continue as the dominant (mean 45%) bottom category in this formation, followed by the crustose calcareous algae (27%). As in 1972, Porites lobata is in general the most abundant hard coral species but Pocillopora spp. can dominate in the shallow zone. Among observed coral degradation agents and signs, current mortality was also frequent but affected only small areas of the colonies and was related to diseases or fish grazing in most cases. The presence of coral diseases in the Colombian Pacific is here recorded for the first time; the most frequent is similar to the White Band Disease (WBD) and was observed attacking Pocillopora spp. An event of strong wind and ocean swell occurred during this study, resulting in considerable physical damage on reef structure and coral colonies at “El Arrecife”. This damage included extensive fragmentation of Pocillopora branches, as well as overturning, fragmentation and scraping of many colonies of massive species.

A list of 46 species of marine macrophytes (44 algae and 2 seagrasses) collected between 5 to 36 m depth off Riohacha, on the continental shelf of the peninsula La Guajira (Colombian Caribbean) is presented. 22 species of algae were not previously known from this area. A total of 149 apecies are now registered from the area of La Guajira. Three types of macrophyte asociations were found: (1) dominated by the seagrass Thalassia testudinum with a dry leaf biomass between 27 and 40 gm-2 at 5 m depth. (2) established at -17 m and also dominated by T. testudinum, but with a lower dry leaf biomass (14 gm-2) and a more scattered distribution; green rhizophytic macroalgae (Caulerpa spp.) are quite common. (3) dominated by red and green macroalgae with a total dry biomass of 14 gm-2 at -36 m. 92 % of the species found occurs also in the Santa Marta region, located 160 km far W-SW from the study area. In general, the species found are widely distributed in the Caribbean.

Authors: Reyes F. Javier , Navas S. Gabriel R.
Published: October 2017

The Flat Bed Scaner, a helpfull tool for marine organisms cataloguing.A cheap and versatile methodology  to get digital images of dry and wet preserved organisms, using a flat bed scanner, is presented. To obtain the images of  wet specimens, a shallow  pool was glued on top of the scanner glass. The pool is filled with water or alcohol and the organisms are immersed and their structures expanded. The best images were obtained with organisms between 1.5 and 15 cm in length. The depth of field was limited to 1.2 cm. These images are also useful for taxonomical research without the need of manipulating the organisms;  they can be used too, to compare with better accuracy certain structures between different specimens.

ESQUEMAS DE DISTRIBUCIÓN DE ESPONJAS ARRECIFALES (PORIFERA) DEL NOROCCIDENTE DEL GOLFO DE URABÁ, CARIBE SUR, COLOMBIA
Authors: Valderrama Diego , Zea Sven
Published: October 2017

The North-West of Urabá Gulf in the Southern Caribbean supports a variety of coral reef zones in conditions of high turbulence and fluctuating turbidity and salinity. Sponge composition and density were surveyed and their relationship with physical and structural features of the reef zones were analyzed. In total, 65 demosponges and 1 calcareous sponge species were encountered along belt transects (20 m2) on 11 stations between 1 and 17 m in depth. Sponge density in Urabá tended to be higher than in other areas with water conditions optimal for coral reef development (i.e. Roncador, Serrana and Quitasueño remote oceanic atolls in the SW Caribbean, Colombia) due possibly to higher concentrations of organic suspended materials discharged from rivers. Nevertheless, this effect was not reflected in the Urabá‘s species richness as just a limited number of species (Niphates erecta, Iotrochota birotulata and Mycale laevis) had high densities. Multivariate analyses showed that sponge community composition varies along a depth gradient and across habitats (coral and geomorphological zones), similar to the patterns observed in other Caribbean areas. However, marked taxonomic differences between shallow (<4 m) and deeper (>6 m) zones and the great increase of the sponge density below just 6 m, seem to be a unique feature of Urabá. The absence of many species and the low abundance of sponges in shallow zones (< 6 m) may be due, not only to the variables associated to low depth, like turbulence, which is periodically very strong, but also to great fluctuations in surface salinity due to discharges of the Atrato and other local rivers. The shallow and deep stations that had low sponge richness and density, showed the greatest urchin densities (especially Echinometra viridis); therefore, it is possible that these urchins may be playing an additional controlling role on sponge populations.
COMPARACIÓN DE LA ABUNDANCIA Y DISTRIBUCIÓN DE ALGUNAS CARACTERÍSTICAS DE LAS ESPONJAS DEL GENERO Ircinia (PORIFERA: DEMOSPONGIAE) EN DOS LOCALIDADES CONTRASTANTES DEL AREA DE SANTA MARTA, CARIBE COLOMBIANO
Authors: Parra Velandia Fernando J. , Zea Sven
Published: October 2017

In tropical littoral environments, suspended organic matter favors the presence of sessile filter feeder organisms such as sponges, over those predominantly phototrophic such as algae and corals. In the Santa Marta area in the Colombian Caribbean, productivity is enhanced by alternating pulses of coastal upwelling and continental runoff, resulting in an important diversity and abundance of sponges. Species of the genus Ircinia (I. campana, I. felix and I.strobilina) are conspicuous and abundant in the rocky and reef biotopes of the area. To establish the influence of predominant environmental conditions on the distribution of these three species, their density, size and microhabitat preference, their form and color, the occurrence of predation signs, the incidence of epibionts and the existence of aggressive interactions with neighbors, were compared across depth (5-20 m), in two localities contrasted by their turbidity and turbulence regimes. As in other Caribbean areas, the general ranking of abundance was Ircinia felix>I.strobilina>I. campana, indicating intrinsic differences between species in their life history traits. In apparent relationship to the amount of suspended organic matter, the main food source for these species, it was found that density and individual size were significantly greater in the locality with turbid and calmer waters, in comparison with the locality with clearer and more turbulent waters; density was also greater in shallow and mid depths in the more turbid locality. Related to the effect that hydrodynamical forces exert on the shape of sessile organisms, the lower forms predominated in the more turbulent locality at all depths, and were proportionally more frequent in shallow waters than in deeper waters in the more calmer locality. The latter is perhaps due to the sporadic occurrence of generalized strong swells in the area. In these species the intensity of the color decrease with decreasing light (with depth and comparing cryptic vs. open microhabitats). The lower light penetration of the locality with greater turbidity also implied a slightly greater proportion of individuals with lighter colors in shallow waters. In the two localities, these species are found preferentially exposed to the light and on hard substratum, although I. strobilina could be often found tightly anchored to rubble. Predation signs and epibiosis were rare, in correlation with know chemical defenses. Although during the sampling clear cases of space competition were not recorded, in the study area these species can partially overgrow coral tissues.
