Matthew Pintar: PhD. Student

I am a PhD student with research interests that focus on the impacts of changing environments and other abiotic factors on aquatic organisms. I am particularly interested in the developmental and life history consequences for organisms that result from the habitat choices their parents made when selecting a breeding habitat. Currently, I am investigating the impacts of water fluctuations on gray treefrog habitat selection and larval development. This includes the effects of varying hydroperiod length as well as the addition of fish and nutrients via flooding at different points in larval treefrog development.

Lauren Eveland: MS Student

My research interests are in the ecology, behavior, and conservation of herpetofauna. I think it is important that researchers start and in some cases continue to incorporate an organisms ecology and behavior into research questions. For my thesis I am looking for the cues Gray treefrogs use to avoid predators when selecting an oviposition site. Previous research has found females avoid laying eggs in locations where predators are present, but the act of oviposition has not been physically observed by the researchers. Data collection occurs the morning after oviposition. The eggs are collected from the experimental ponds, and then counted in a lab. Therefore, my project consists of physically observing the behavior of male and female gray treefrogs at night.

Robert Bruner: PhD. Student

A wealth of research exists studying how insects detect and utilize host plants as habitat patches and oviposition substrates; however, research into aquatic insect habitat selection is still lacking in several areas. The research that I conduct examines the stimuli used by aquatic insects in their habitat selection choices. Specifically, I'm research how the presence of plant volatiles influences the oviposition site selection of aquatic beetle taxa. By determining how plant volatiles play a part in the oviposition of these insects, I hope to be able to apply models developed in terrestrial systems to aquatic insects, as well as shed further light on what cues these insects use in habitat selection.

Jason Bohenek: PhD. Student

My research interests focuses on evolutionary, chemical and information ecology. I am interested in how organisms acquire information in order to influence morphotype in polyphenic species. Amphibians provide an ideal model to study this question given their complex, multi-stage life cycles. In particular, I am investigating which proximate environmental cues are used by facultatively paedomorphic salamanders to assess and select habitat (aquatic vs. terrestrial). Aquatic chemical ecology is an emerging field and the chemistry of this system is widely unknown. I use both ecological field experiments and analytical chemistry to tease apart the underlying mechanisms of this system.
