Explaining variation in American lobster (Homarus americanus) and snow crab (Chionoecetes opilio) abundance in the northwest Atlantic Ocean.

The goal of my Doctoral research is to assess the causes of long-term changes in American lobster (Homarus americanus) and snow crab (Chionoecetes opilio) populations in the northwest (NW) Atlantic. Through analyses of available time series including commercial landings, research surveys, catch per unit effort, and local ecological knowledge, I am exploring a reported ecosystem shift in the NW Atlantic. This shift entails a region-wide decline of groundfish resources and an increase in benthic invertebrates, including large, commercially valuable decapods. I am examining multiple hypotheses relating to the causes of this shift, including changes in temperature and predation.

Macroecological changes in the open oceans

The goal of my project is to quantify and better understand the patterns and processes which structure open ocean ecosystems. I will use statistical methods to estimate changes in abundance of oceanic species ranging from phytoplankton to apex predatory fishes, as well as to explore the drivers and consequences of any observed changes.

Interested in intraspecific diversity and its role in ecosystem functioning.

During my Ph.D. - supervised by Boris Worm and Thorsten Reusch - I analysed the role of genotypic diversity in eelgrass Zostera marina for the resistance and resilience of eelgrass meadows under heat stress and eutrophication.

Currently I am working as a Post doc at the IFM-Geomar, Kiel, Germany trying to unravel the defence mechanisms of the brown algae Fucus vesiculosus, by comparing transcriptomes of grazed vs. ungrazed individuals.

Hilary Goodwin
MMM Student

I am in the Marine Affairs Program at Dalhousie University working toward a Master of Marine Management degree. My graduate project will focus on examining and comparing skate management in Atlantic Canada and the United States, and will provide an overview of current threats, conservation efforts, and recommendations for improved bi-lateral management. Over the course of my degree, I will intern at the NOAA Fisheries Office of International Affairs and at the Shark Advocates International Office in Washington, DC.

I am particularly interested in international elasmobranch conservation and believe international dialogue is critical to conserve highly migratory species. Skates have similar life history characteristics to sharks and more attention on skate management could result in better protection for skates.

I previously studied International Relations and Environmental Studies at the College of William and Mary. I have spent several years in Washington, DC working in the marine non-profit realm.

The aim of my project is to compare underwater visual survey methods on their estimates of environmental variables. Specifically, I conducted underwater visual census and stereo-video surveys on the same coral reef sites in a marine protected area in Cayos Cochinos, Honduras. I am currently analyzing the results to see how UVC and SVS differ in estimates of species richness, diversity, abundance, and biomass. Based on my results, I will assess the suitability of each method in measuring these variables, as well as some advantages and disadvantages of each method, (although more research will be needed to provide a complete assessment). The results of this research could greatly change the current trends in data collection, and provide better information for management of marine resources.

My research makes use of species distribution models to document and understand human-induced changes in the occurrence of individual species and in patterns of biodiversity. Species distribution models identify statistical relationships between species occurrence on the one hand and environmental and anthropogenic factors on the other. They are thus useful tools in estimating the likelihood of species occurrence where survey data are lacking, and can provide useful clues as to the causes of distributional change.

My work applies these types of models to the distributions of Pacific reef fish species to examine the impact various levels of fishing pressure have had on species' occurrence, abundance and community composition. It forms part of the Pacific Reef Fish Collaboration , which I coordinate, and the Lenfest Oceans Marine Extinctions Project.

My previous research has ranged from studying the international trade in seahorses to modeling the distributions of 1500 bird species in southern and eastern Africa. More details and a list of publications are available on my website.

Meta-analysis of multispecies interactions and the affect on recruitment in demersal fish stocks

My project focusses on incorporating multispecies effects into latent variable covariance models that have been used to estimate density dependence within species (see Myers and Cadigan, 1993). Using long-term survey data from many different stocks, it is possible to elucidate the underlying trends. Part of my project focusses in particular on Irish Sea demersal assemblages.

Conservation strategies worldwide are designed around species distributions and biogeographic patterns, often under the assumption that these patterns are relatively stable. With climate change, however, distributions are now shifting as species seek more suitable conditions. There is an urgent need for credible predictions of future species distributions to guide conservation planning. Nowhere is this more evident than in the ocean where range shifts are up to an order of magnitude faster than on land. By using 50 years of observational data provided by research trawl surveys on the continental shelves of North America, this project will develop validated, process-based predictions of future marine species ranges along this continent. As opposed to previous efforts, this project will directly test models against past observations with hindcasting, and then use the best models for prediction. These models will consider climate, dispersal, and species interactions. Products from this research will include: 1) validated models for predicting marine species distributions along the continental shelves of North America, 2) predictions of future shifts in species distributions driven by climate change, 3) forecasts of future biodiversity hotspots and ecoregional boundaries, and 4) evaluation of existing marine conservation plans in light of future species distribution shifts.

For my Ph.D. project I am investigating spatially and temporally explicit models to evaluate the effects of large-scale fisheries closures on marine animal populations. The use of large-scale time-area closures has been used as a conservation measure to rebuild depleted stocks. My project looks at the ecological aspects of such closures and aims at developing a framework to guide their design, implementation and evaluation.

Mapping biodiversity and human impact drivers to assess high-seas conservation priorities

I'm broadly interested in marine ecology, conservation planning and prioritization. In particular, I'm interested in the role that apex predators play in structuring marine ecosystems and contributing to their resilience, and how planning can accommodate this. I visited the Worm lab during the summer of 2008 while working on the research project for my MSc in Biodiversity Conservation and Management at Oxford University. My project examined the association between human impact drivers and tuna and billfish species richness to help develop conservation priorities in the High Seas.

Christine Ward-Paige
Post-Doctoral Fellow

I am primarily interested in quantifying the extent of human-induced changes on marine communities and in evaluating the need for and success of different management initiatives. In my research I strive to place contemporary patterns in context with long-term changes.

I also developed and run, a project that facilitates and collects statistically useful data from marine resource users, including scuba divers, snorkelers and fishers. Because eShark data are standardized among regions and resource users, the information is valuable for myself and other scientists in the assessment and monitoring of local and global marine animal populations.
