Why species occupy the habitats they do and what drives the fluctuations in their numbers are questions that are fundamental for understanding biodiversity; the answers are essential for conserving it. Organisms confront many challenges in their environment, from obtaining the energy needed to grow and reproduce to coping with an array of competitors, predators, and pathogens. Global change, whether via climatic shifts, the advent of invasive species, or habitat loss and fragmentation, is creating new challenges and changing the nature of biological communities and the composition of ecosystems. Ecological research has uncovered enormous complexity in the relationships of organisms to their environments and the challenge now is to distill that complexity into principles that will help us manage our ecosystems and preserve our biodiversity in a rapidly changing world.
My research combines ecological and evolutionary principles to study the population biology of coastal marine species (mainly invertebrates such as bryozoans and corals). Topics studied include larval dispersal, population connectivity, population dynamics, life history evolution, adaptive phenotypic plasticity, maternal effects, and local adaptation. I typically use some combination of field and laboratory experiments, field surveys, and mathematical modeling.
I study population dynamics, with a focus on predator-prey, host-pathogen, and other exploiter-victim systems. I use mathematical models to explore how adaptation and species interactions drive patterns observed across communities.
My research program explores the evolution of social behavior in animals, particularly birds, with an emphasis on cooperation, sexual selection, and reproductive strategies.
At each level of organization, from genes to species to communities, one of the most exciting aspects of biology is diversity. Why do some communities consist of so many species, when others are dominated by just a few? The central goal of my research program is to join theoretical and empirical approaches to understanding population dynamics and community structure.
I am interested in the ecology and evolution of marine invertebrates. My work examines the interactions between ecological processes, natural and sexual selection, and molecular evolution. I am particularly interested in how sperm availability and population density influence the evolution of gamete traits and reproductive behavior and the cascading effects of this selection on reproductive isolation and speciation. I enjoy integrating field experiments and molecular studies with theory.
I am a community ecologist with broad interests in ecology, evolution, physiology, and environmental chemistry. My research focuses on macroalgal populations, intertidal communities, and links between biology, environmental conditions and water chemistry. I use a combination of field and laboratory methods to understand natural variability in marine populations, responses of individual species and communities to climate change and pollution, and feedbacks between biology and water chemistry.

At the heart of my interests is the problem of how ecology and evolution combine to determine the number and abundances of species in communities.
Is study population dynamics with a particular focus on marine species. I am interested in how environmental and trophic interactions regulate fluctuations in demographics (i.e. recruitment, growth, reproduction and mortality) and population size, and how management (especially in fisheries) impacts such dynamics in space and time. My research integrates field and laboratory experiments, field surveys, statistical analysis, mathematical theory and simulation modeling. Primary research taxa thus far include sea urchins, marine macroalgae, forage fish, reef fish and abalone.
I am a quantitative marine ecologist with research interests straddling the linked fields of natural resource management and ecosystem resilience. I combine field experiments, data analysis and mathematical modeling to address basic and applied questions in temperate and tropical reef ecosystems.
I am interested in how and why the features of animals, particularly freshwater fish and amphibians, vary from one population to another. Variation among local populations of the same species represents the earliest stage in the adaptive generation of biodiversity and understanding that variation can give us insights into a variety of ecological and evolutionary processes that affect life histories, morphology, behavioral patterns, and even physiological responses.
I am a population biologist interested in the ecology and evolution of plant-insect interactions. I study how genotypic and phenotypic variation among individuals affects the long-term spatial and temporal dynamics of plant, herbivore and pollinator populations. I have field projects in both Florida and at the Rocky Mountain Biological Laboratory in Colorado.
I study plant population biology, life-history evolution, and ecological genetics.
I study the ecology of sponges and the organisms with which they interact as mutualistic partners, competitors, and prey, especially in coral reefs, seagrass meadows, and mangroves.
I am currently studying the evidence for the widely accepted hypothesis that birds are maniraptoran theropod dinosaurs and developing a model that characterizes forest-management options and their relative likelihood of providing sustainability for the full biodiversity of the longleaf-pine ecosystem
Geographic variation in sexual selection.
My primary research is on coral reefs from shallow waters to the deep sea. My focus is on understanding their distribution, abundance, and physiology, as well as how they are affected by anthropogenic impacts.
My research focus is marine ecology, particularly as it relates to reef fishes and their interactions with other species in their community and their habitat.
My research interests are in ichthyology and marine ecology with an emphasis on the biology of coastal, pelagic, and deep sea fishes. Much of my research focuses on exploited, imperiled, or poorly studied elasmobranch species and is often directed towards answering questions necessary for sustainable management and conservation of their populations. I am particularly interested in the drivers of community structure and habitat use patterns as well as population dynamics and life history variability.
My research is focused on economically important reef fishes of the southeastern United States. Subject areas include studies of absolute abundance and survival in nursery habitats, demographics of reproductive groups on offshore spawning sites, deep-water coral-reef restoration, and trophic interactions of marine fishes.
