title: An Investigation of the Effects of Patch Size, Local Adult Abundance, and Grazing Patterns of Interdidal Algal Succession

description: The patterns and mechanisms of succession in clearings in mussel beds are being investigated with field experiments. Patches cleared in the dominant cover of mussels constitute the major source of heterogeneity in the distributions of species in the mid-intertidal zone. Three factors largely determine the patterns of succession which follow such local disturbances: the size of the clearing, the local abundances of adult plants whose spores can disperse into the clearing, and the abundance of grazers within the clearing. By experimentally creating patches of different sizes and then manipulating the densities of grazers, I have been able to demonstrate strong patch size-grazer interaction effects. These result in markedly different successional patterns in patches of different size. I am continuing to monitor these patches to see if the amount of recruitment to a patch is correlated to the abundances of adult plants surrounding it. If so, this will be some of the first solid evidence of the limited dispersal of spores by marine algae.

title: Aquaculture: Nutrition/Feed Development

description: The Nutrition Group is interested in crustacean nutrition with the majority of our research being focused on the lobster (Homarus americanus). One of the goals of the program is the development of an optimum nutrient profile for the lobster which will serve as a guideline for a commercial ration. Research is also conducted on defining other nutritional parameters, such as consumption, assimilation, and food conversion, which will be important to the commercial lobster aquaculturist. We have found that addition of a phospholipid (lecithin) to the diet of juvenile lobsters eliminates "molt deaths," which were responsible for up to 70% of the juvenile lobsters that died when fed previous artificial diets. The specific component of lecithin which is essential, was found to be phosphatidylcholine, a compound which lobsters apparently cannot synthesize at a rate high enough to meet their physiological needs. The effectiveness of phosphatidylcholine in reducing mortality related to the molt death syndrome is dependent on the source of the compound. Phosphatidylcholine molecules which are comprised of long-chained polyunsaturated fatty acids are the most effective. Further research has indicated the physiological role of phosphatidylcholine is related to the transport of cholesterol, an essential nutrient for lobsters as well as all other arthropods which are incapable of synthesizing this sterol. Although a basic outline has been developed as to the role of phospholipids in lobster nutrition, a number of detailed questions have yet to be answered as to optimum dietary levels of phospholipids and cholesterol, in order to maximize ration efficiency. Continuing studies will extend these findings, evaluate the effects of other dietary components, and test particular diet mixes in long-term lobster growth experiments. Two graduate students, Michele Bronstein and Karen Norman, are working under the direction of Dr. Conklin in the Nutrition group. Michele Bronstein, who joined the laboratory this summer, is a graduate student at UC Davis, being jointly sponsored by Dr. Duane Brown of the Food Science and Technology Department and by Dr. Conklin, is examining the role of Vitamin D metabolites on the physiology of fish. She is particularly interested in aspects of comparative physiology comparing a typical bony fish, the catfish, and the sturgeon, which although evolutionarily a bony fish, has reverted to the more primitive cartilaginous skeleton. Michele has refined and optimized existing HPLC (High Pressure Liquid Chromatography) techniques, specifically for analyses of Vitamin D metabolites in fish serum. Karen Norman, a Ph.D. student in the Nutrition Graduate group at UC Davis, is investigating amino acid metabolism in the lobster, Homarus americanus. Preliminary feeding trials have indicated that the amino acid profile required by lobsters may be unique. Further investigations will allow for optimization of protein quality in commercial lobster rations, and should help in the movement of lobster aquaculture from the lab to commercial reality.

title: Aquaculture: Water Quality/Analytical Chemistry

description: The Water Quality Laboratory maintains EPA and state required self-monitoring of BML seawater discharges, performing state certified chemical analyses. Additionally, this group monitors water quality within aquaculture systems and participates in analytical research within the aquaculture program. During this past year, the Water Quality lab met all requirements state for maintaining certified status for the water quality lab at BML, and assisted other aquaculture groups with water quality analyses. The Water Quality/Analytical Chemistry Lab participated with the Nutrition group in developing improved techniques for the analysis and identification by high resolution gas chromatography of long chain fatty acids associated with the lipid requirements in crustaceans. The lab also performed hydrogenation of long chain fatty acids for the Nutrition group. The service and research functions of this lab are expected to continue.

title: Factors of Non-Breeding Habitat in Shorebird Social Systems

description: This research, now in its 6th year, deals with the population ecology of a wintering shorebird, the sanderling Calidris alba and its invertebrate prey. We are concerned with three major research areas: (i) the influence of resource abundance and predation risk on sanderling spacing behavior: (ii) the effects of shorebird predation on their invertebrate prey: and (iii) temporal and spatial definition of shorebird populations along coastal California. Our work on sanderling spacing dissects ecological factors governing the wide variability observed in their behavior, from tight flocking to strong territorial defense. This is a field study, and it involves long-term, intensive monitoring of prey abundances, of sanderling predators (chiefly raptors), and of sanderling behavior. A major part of the work is describing time-space distributions of invertebrates exploited by sanderlings on outer beaches. Chief among these are the sand crabs Emerita analoga and isopods Excirolana spp. This field sampling has been complemented by extensive analyses of caloric values of invertebrate prey, as well as laboratory experiments on the factors governing prey availability to sanderlings. The study on shorebird effects on their invertebrate prey centered around a series of bird exclosures set out in Bodega Harbor from October 1980 - March 1981. These cages kept out birds but allowed in fish. An intricate sampling method allowed us to combine measurements of prey density with information on caloric values of prey and on factors controlling prey availability, thereby permitting the effect of shorebird predation in to be calculated terms of a reduction in caloric intake rates of birds feeding in control plots vs. exclosures. Birds had strong and significant prey to removed effects: they enough decrease their caloric intake rate by 41%. Our research on the temporal and spatial definition of shorebird populations focuses on movements by sanderlings among different estuary-beach systems in central coastal California. We have discovered a strong seasonal pattern in the degree of vagility of sanderlings wintering examine monitor this Bodega Bay. To at we turnover rates of individuals within the local population, and also make periodic expeditions to surrounding areas in search of color-marked individual birds. This research has important practical implications because it reveals that environmental disturbances may a far affect local greater set of shorebirds than indicated by simple static censuses of an area. This research is supported by the National Science Foundation. In addition to the staff listed above, periodically through the winter we employ 5-lO students for invertebrate sampling. One member of the staff, G. Ruiz, has now become a UCB graduate student and will center his dissertation around aspects of this work. As of July a UC Santa Cruz senior, Richard Culver, has begun his senior thesis under our direction. Through the past year, Dr. J.R. Walters associated with our program as an NSF Post-doctoral Fellow.

title: Improved Procedueres for Salmon Management in California: Bieconomic Approaches

description: During the first year of this project we have acquired access to the extensive and scattered salmon database. Through this process we have developed closer cooperation with members of the Anadromous Fisheries Division of the California Department of Fish and Game. Currently we are assisting them in improving the statistical analysis of tagging studies used to estimate escapement. One result of our studies of the salmon fishery is the identification of cycles in the northern California salmon catch. These cycles have the same period, 9-10 years, as the cycles in Dungeness crab catch but salmon catch peaks 3-4 years earlier than crab catch. In a manuscript, recently submitted to Fishery Bulletin, we investigate and reject the hypothesis that the cycle in salmon catch is due to reduced salmon fishing effort during years of high crab catch. Currently we are working on improving past estimates of salmon recruitment and are exploring biological and environmental mechanisms which may cause variation in salmon abundance and catch. The dynamics of the salmon fishing fleet are being characterized through analysis of an intensive 3-year coastwide survey.

title: Invertebrate Behavior and Ecology

description: Three projects neared completion during 1980-8l: Steroid saponins, chemicals which are thought to elicit defensive behavior by many marine invertebrates, were isolated directly from seawater surrounding living specimens of two species of seastar, Pycnopodia helianthoides and Patiria miniata. The total amount of saponin released by equal wet weights of these two seastars is similar, but structural details of specific saponins may differ. Two other projects dealt with the defensive responses of certain prey to predators. One of these (with Marina Chiarappa) investigated the defensive responses of limpets to predatory flatworms. The other project was an investigation of the responses of two stenotopic limpets, Collisella instabilis and Notoacmea insessa, two seastar predators. In addition to the research described above revision of Between Pacific Tides has begun. Numerous photographs and collections will be taken at BML to support this work.

title: Box Springs Reserve Annual Report

description: The Box Springs Reserve has been used primarily as an outdoor laboratory for field biology classes. It is also used by students as the site for research projects that are connected with these field classes. During the spring one of the classes discovered two species of terrestrial molluscs (snails) that were not known to occur in this area. They both are reported to have a rather limited distribution. The name of one of these animals has not been definitely established yet, although both have been identified to genus. They are: Helminthoglypta tudiculata Glyptostoma sp. either gabrielense or newberrianum Some permanent plant and animal transects have been established on this Reserve. We plan eventually to have these transects located on a map of the Reserve so that they may be used by any groups that desire to do so. Some photo sites have also been established, so that a photographic record of the Reserve can be maintained from known locations. Pictures will be taken along marked compass bearings from each of these sites so that changes which may occur on the Reserve will be recorded.

title: Additional Habitat for the Desert Slender Salamander

description: The project of perhaps the greatest interest to herpetologists was a brief survey conducted by Derham Giuliani, under auspices of the Bureau of Land Management, from early January through late spring. He conducted a search for additional habitat for the Desert Slender Salamander, heretofore known only from one location adjacent to the Center in the Hidden Palms sector. Giuliani is believed to have found an additional population, on Deep Canyon land, in Guadalupe Canyon. It has not been determined positively that the new population is the same species, but it is a "probable" extension of the range of this species.

title: Mortality Factors Among Yearling and other Juvenile Bighorn Sheep

description: The most ambitious program undertaken in the 1980-1981 year concerned the most famous mammal residents of Deep Canyon and the Santa Rosa Mountains, Ovis canadensis cremnobatis, popularly known as the peninsular bighorn sheep. A student-agency team headed by Jim DeForge, doctoral candidate at the University of California, Davis, and Joan Scott, master's candidate at the California State Polytechnic University, Pomona, spent more than 500 hours in the field studying mortality factors among yearling and other juvenile sheep. They worked from Bradley Canyon south as far as Carriso Canyon in the Santa Rosas. The program, which will continue at an accelerated pace in the 1981-82 fiscal year, is being coordinated jointly by the California State Department of Fish and Game and the Society for the Conservation of Bighorn Sheep. Mr. DeForge is the staff biologist for the Society, which has its headquarters in Alhambra. Deep Canyon's role in this vital study is largely confined to housekeeping. That is, providing quarters and ancillary support for Mr. DeForge and Ms. Scott, including use of the reference library, herbarium and other reference collections, as well as campground and building quarters for the research team. The group ranges from two to 20 persons at a time. The penned bighorns at Living Desert Reserve, which are maintained by that private agency under permit from Deep Canyon and the state, also have been studied by the group at the same time free-ranging sheep are being observed, both as a control and also to analyze differences in behavior.
