Dr. Matthew Pintar, Post-doc

Broadly speaking, I am interested in the factors that affect the development, behavior, and life history of aquatic organisms and the structure of aquatic communities. I am investigating how pond age and flooding impact the development of amphibians as well as habitat selection of aquatic beetles and treefrogs. Temporary ponds are dynamic systems defined by periodic drying, but drying is neither an endpoint nor a one-way process. Drying ponds can be replenished via rainfall or flooding, whereas filling a dry pond initiates a new community that is often shaped by the initial abiotic conditions as well as the order of arrival of colonizing organisms.

My research interests lie in aquatic ecology with emphasis on physiological, chemical and information ecology. I am interested in polyphenisms, which are a type of phenotypic plasticity where multiple, environmentally-cued phenotypes arise from a single genotype. I want to know what information organisms utilize in order to cue particular phenotypes. In particular, I am investigating which proximate environmental cues are used by facultatively paedomorphic salamanders to assess and select habitat (aquatic vs. terrestrial); the chemistry and physiology of this system are largely unknown. I use both ecological field experiments and analytical lab techniques to tease apart the underlying mechanisms of this system.

I'm interested in the role of diversity and species interactions in aquatic ecosystems. I am more specifically interested in changes in diversity and behavior due to human influences like climate change, habitat management decisions or introduced species. I am currently examining how climate change may impact the oviposition behavior of mosquitoes (Culex restuans). Moving forward, I would like to continue to pursue this question and also examine studying oviposition choice and ecological tradeoffs in the gray treefrog, Hyla chrysoscelis.

My research interest is in community ecology in freshwater systems. Specifically I am interested in species interactions, food web dynamics, and biodiversity involving aquatic invertebrates. My current project seeks to determine whether the oviposition sitechoice of odonates is affected by the presence of fish predators. I plan on expanding this project to test the affects of novel predators, water quality, and/or intraspecific competition.

My interest is in understanding how habitat selection can drive habitat loss. While most people only think of habitat loss as the direct destruction of habitat, a habitat patch can also be considered effectively lost if that patch is either inaccessible or perceived as uninhabitable. Currently my work focuses on spatial contagion. Spatial contagion is a phenomenon by which attributes of one patch may affect the perceived quality of neighboring patches. Much of the work done on spatial contagion has examined the effects of predators, but predation isn't the only factor involved in habitat selection. In an aquatic system, factors such as competition, desiccation, and resource availability also influence a colonizer's patch choice. By testing these factors for a contagion effect, I hope to elucidate why species might avoid high quality patches and thus inform future management decisions.

Brandon McDaniel, UG Honors student

My project at the Field Station focuses on how the effects of predator dietary cues influence mosquito oviposition. I work with two species of fish to learn more about predator detection through the production of kairomones. I am interested in how fish diets cause changes in reproductive habitat selection.
