My research objectives aim at expanding the knowledge of the biology and ecology of weeds of rice by understanding the physiological bases for their adaptation to irrigated rice environments and their competitiveness with rice. Knowledge on the physiological bases of weed responses to habitat disturbances, and on the processes governing the success of individuals as they proceed along their life stages, will allow better understanding of the bases for the ecological fitness of the weeds of rice. This knowledge is essential to formulate sustainable management strategies aiming at suppressing weeds at their most vulnerable stages. Also my research is aimed at understanding the biology and mechanisms of resistance in herbicide-resistant weeds of rice. Agricultural Ecology.

I study the ecology of infectious diseases: i.e. the interactions of agents of human and mammalian infectious diseases with the environment,vectors, and hosts. Currently, my main area of research is the investigation the natural history of a rickettsia, ehrlichia equi, in humans, dogs, horses and wildlife, as well as the ixodid tick vector. I am interested in the broad scope of the problem, from the process of disease induction, to maintenance of the disease agent in nature, to modeling the population processes of disease agent and host interaction. My research with this agent and other pathogenic microorganisms regards the organism-host systems as models to study the underlying ecological processes maintaining infectious diseases in nature.

My research centers on understanding the ecological and evolutionary processes that maintain genetic and phenotypic variation in natural populations. I am particularly interested in the evolution of self/nonself recognition systems, social behaviors, and complex life histories. I use a variety of techniques, including field and laboratory experiments, molecular genetics, and simple models to address questions at the interface of ecology and evolution. I primarily study marine invertebrates; however, my taxonomic interests are agnostic (except for marine mammals). Marine Ecology, Conservation Ecology

I use plant-insect interactions as model systems to ask ecological and evolutionary questions at both the population and community level. I have several main research interests. Currently, I am examining how leaf herbivory by insects affects floral characters, plant pollination biology and, ultimately, male and female plant fitness. These interactions can be tied into current ideas about plant defense theory and costs of resistance/tolerance to herbivory. Along the same lines, I am interested in how selection on resistance characters constrains the evolution of plant attraction and reward characters, and vice cersa. I also am interested in community ecology and how suites of herbivores influence one another in their use of host plants; this research encompasses direct and indirect interactions among herbivores. Insect population dynamics may change in response to controlled burns and habitat management throught changes in host-plant quality; this is another area I am interested in pursuing.

I am broadly interested in the forces that govern populations and communities of marine benthic plants and animals. Current research in my lab is focused on two major areas: 1) the role that positive interactions (mutualism, commensalism) play in structuring marine communities; and 2) the factors affecting the susceptibility of marine communities to invasion by introduced species. I also have an active interest in chemical ecology, examining both direct and indirect ways that secondary chemistry can mediate interactions among marine plants and invertebrates.

My research focuses on shallow nearshore marine and estuarine environments dominated by seagrasses and seaweeds. My current research involves restoration and conservation of marine plant populations, e.g., the importance of genetic diversity and the impacts of invasive species. I also work on plant-animal interactions, particularly how the interactions affect the biogeochemical functioning of plant communities and the fitness of plants. Marine EcologyWilliams, S.L.
