My primary research interests are invertebrate phylogeny and phylogeography. I am primarily interested in the extremes of the molluscan and annelidan radiations. While most mollusks are rather sedentary aquatic animals, some (cephalopods) are active, swimming predators with an array of spectacular ...read full profile >>

I'm an ecologist interested in understanding the drivers of spatial behavioral processes such as movement and habitat selection. I’m also interested in determining how these processes scale up to affect the demography and distribution of multiple sympatric ...read full profile >>

Much of my basic research focuses on the optimal expression of body temperature (i.e. thermoregulation) under varying ecological conditions as well as the evolutionary history that has led to the patterns of thermoregulation we see today. I use a multitude of approaches including non-manipulative ...read full profile >>

The overarching goal of my research is to develop a conceptual framework for understanding the interplay between spatial, genetic, ecological, and evolutionary processes.  I integrate theoretical perspectives on evolution, ecology, and population genetics with geospatial, field-based, and ...read full profile >>

Dr. Eichholz is a waterfowl/wetland ecologist in the Cooperative Wildlife Research Laboratory and Assistant Professor in the Zoology Program, Southern Illinois University. His past and current research involves studies addressing the importance of nutrient reserves to clutch size and incubation ...read full profile >>

Many investigators have assumed that the bioenergetics of ectotherms respond similarly to conditions along environmental gradients. My colleagues and I have been challenging this view, finding that energetic adaptations can influence growth and behavior of fish along broad latitudinal gradients. ...read full profile >>

I am interested in the spatial and temporal dynamics of genes in natural populations. My current research focuses on the conservation genetics and molecular systematics of the fauna of the Horn of Africa with emphasis on ungulates (along the Red Sea coast), mosquitoes (northern Sudan), and termites ...read full profile >>

My research interest focuses on the historical relationships among nematodes and their mammalian hosts across the neotropics. I dissect the macroevolutionary histories of both mammals and parasites to identify the processes that resulted in faunistic diversification in the New World. In my lab we ...read full profile >>

My areas of research interest include evaluating the effects of chemical mixtures, developing a basic understanding of the chemical and biological factors affecting toxicity, bioavailability and bioaccumulation, remediation of contaminated sites and evaluating the effectiveness of Best Management ...read full profile >>

My research examines the causes and consequences of patterns in freshwater nutrient availability. Drawing from the fields of ecological stoichiometry, biogeochemistry, and disease ecology, I examine how traits of organisms respond to and shape the nutrient dynamics around them. Parasites are ...read full profile >>
