    mechanisms that generate patterns of habitat use This work is being carried out at the U C Berkeley Gump Biological Station Moorea French Polynesia We recently received renewal funding from NSF for an additional 5 years July 2000 July 2005 2 Temporal patterns in reef communities This work investigates long term trends in population abundance species richness and species composition of nearshore reef fish communities There is increasing interest in the response of communities and their component species to temporal environmental variation especially in the context of global warming and other long term trends During the past few years my colleagues and I have been analyzing available data for Southern California reef fishes We have found that nearshore reef fish communities respond to environmental variation such as El Nino events in predictable ways but tend to recover rapidly Our findings also indicate that these communities have responded strongly to temperature and productivity changes that have occurred during the past 20 years in the Southern California Bight with many populations of reef fish and other benthic organisms declining on the order of 80 in the past decade It is not clear whether any of these changes are signals of global warming This work has involved analyses of two of the longer data sets for unharvested reef fishes that exist in Southern California data for 5 species at Santa Cruz Island collected by Russ Schmitt and me and that of John Stephens Jr for two communities of fish south of Los Angeles In collaboration with Dr Andy Brooks we have been exploring temporal patterns of abundance in several trophic levels and for a variety of types of organisms in the Southern California Bight To date this work indicates that the various species have responded similarly This result contrasts with the predictions of several current models of marine communities The recently awarded NSF Long Term Ecological Research program for the Santa Barbara Channel will afford an opportunity to experimentally explore effects of environmental perturbations on species that inhabit nearshore kelp bed communities 3 Development of restoration techniques for surfgrass Dan Reed of the Marine Science Institute and I are collaborating on a project to investigate the biology of surfgrass Phyllospadix torreyi in some detail and to use this information to develop restoration techniques for beds of surfgrass that have been damaged or destroyed Surfgrass is one of the most important structural components of the intertidal and shallow subtidal rocky shore in Southern California providing habitat for fish and many important invertebrates This species is easily damaged by anthropogenic activities and because it lives attached to rocks in a high energy zone successful propagation and restoration techniques have yet to be developed We have funding from the County of Santa Barbara and the Minerals Management Service to find out whether early life history stages seeds seedlings of Phyllospadix could be used in restoration attempts The usual technique for other species of seagrass is to outplant older stages This is a successful approach in the

    impact of infectious diseases in fisheries culminated in a model showing that diseases could cause great losses in fisheries which critically depends on the relative scale of host and parasite recruitment and on fishery management Thus changes in management strategy can reduce losses to disease and increase the fisheries yield Several crab fisheries are now being consciously managed using this principle In 1993 with the coming of the pestiferous European green crab Carcinus maenas to California we began investigating a marine pest biocontrol program using parasitic castrators as natural enemies In addition we are dealing with public policy issues and are developing specifics for biocontrol of the European green crab in California and Tasmania Our principal goals are to ensure that biocontrol agents will not damage native species and to understand the conditions whereby biocontrol will be effective in the marine environment In association with the work on control of marine pests we are also assessing the sabellid pest Tetrabrasabellida heterounicinata of abalone and other mollusks This highly politicized introduced pest from South Africa has caused great economic damage to the California abalone aquaculture industry Now the sabellid pest poses an environmental threat of unknown magnitude as it has been released and is established in at least one natural location Our current research includes studies of host specificity the mechanism of shell damage and the sabellid s distribution abundance and host use in South Africa For many years we have sought a biocontrol approach to the major tropical disease human schistosomiasis As part of a large team from UCSB University of New Mexico Kenya Medical Research Institute and The Kenya Division of Vector Borne Diseases we have just completed the critical test of the ability of Louisiana crayfish to block transmission of urinary schistosomiasis to school children by feeding on the snail intermediate hosts Control was achieved Consequently prevalence dropped from 68 to 20 in treated children at one heavily infected school Further work will involve the effect of crayfish on aquatic communities in Kenya and understanding the environmental conditions required to sustain crayfish impoundments at transmission sites In order to apply these ecological principles we are actively seeking a major expansion of our funding base for appropriate technology to this important tropical disease Selected Publications Miura O A M Kuris M E Torchin R F Hechinger and S Chiba 2006 Introduced cryptic species of parasites exhibit different invasion pathways Proc Nat Acad Sci in press Hechinger R F K D Lafferty T C Huspeni A J Brooks and A M Kuris 2006 Can parasites be indicators of free living diversity Relationships between species richness and the abundance of larbal trematodes and of local benthos and fishes Oecologia in press Miura O A M Kuris M E Torchin R F Hechinger and S Chiba 2006 Parasites alter host phenotype and create a new ecological niche for snails Proc Roy Soc London Ser B 273 1323 1328 Lafferty K D A P Dobson and A M Kuris 2006 Parasites dominate food
