  • Move it or lose it: interspecific variation in risk response of pond-breeding anurans. [Journal Article]
    PeerJ. 2019; 7:e6956.Matich P, Schalk CM
  • Changes in behavior are often the proximate response of animals to human disturbance, with variability in tolerance levels leading some species to exhibit striking shifts in life history, fitness, and/or survival. Thus, elucidating the effects of disturbance on animal behavior, and how this varies among taxonomically similar species with inherently different behaviors and life histories is of val…
  • Habitat predictors of genetic diversity for two sympatric wetland-breeding amphibian species. [Journal Article]
    Ecol Evol. 2017 08; 7(16):6271-6283.McKee AM, Maerz JC, … Glenn TC
  • Population genetic diversity is widely accepted as important to the conservation and management of wildlife. However, habitat features may differentially affect evolutionary processes that facilitate population genetic diversity among sympatric species. We measured genetic diversity for two pond-breeding amphibian species (Dwarf salamanders, Eurycea quadridigitata; and Southern Leopard frogs, Lit…
  • Joint effects of resources and amphibians on pond ecosystems. [Journal Article]
    Oecologia. 2017 Jan; 183(1):237-247.Rowland FE, Rawlings MB, Semlitsch RD
  • Primary production can be controlled through bottom-up (e.g., resources) or top-down (e.g., predators) constraints. Two key bottom-up resources in small aquatic systems are light and nutrients, and forest canopy cover heavily influences these factors, whereas amphibian and invertebrate colonizers exert top-down pressure as grazers and predators. We designed our experiment to specifically manipula…
  • Mismatched anti-predator behavioral responses in predator-naïve larval anurans. [Journal Article]
    PeerJ. 2015; 3:e1472.Albecker M, Vance-Chalcraft HD
  • Organisms are adept at altering behaviors to balance the tradeoff between foraging and predation risk in spatially and temporally shifting predator environments. In order to optimize this tradeoff, prey need to be able to display an appropriate response based on degree of predation risk. To be most beneficial in the earliest life stages in which many prey are vulnerable to predation, innate anti-…
  • The effects of a fungicide and chytrid fungus on anuran larvae in aquatic mesocosms. [Journal Article]
    Environ Sci Pollut Res Int. 2015 Sep; 22(17):12929-40.Hanlon SM, Lynch KJ, … Parris MJ
  • The amphibian disease chytridiomycosis, caused by the pathogenic fungus Batrachochytrium dendrobatidis (Bd), has been linked to significant amphibian declines over the past three decades. The most severe effects of the pathogen have been primarily observed in relatively pristine areas that are not affected by many anthropogenic factors.One hypothesis concerning improved amphibian persistence with…
  • Daphnia predation on the amphibian chytrid fungus and its impacts on disease risk in tadpoles. [Journal Article]
    Ecol Evol. 2013 Oct; 3(12):4129-38.Searle CL, Mendelson JR, … Duffy MA
  • Direct predation upon parasites has the potential to reduce infection in host populations. For example, the fungal parasite of amphibians, Batrachochytrium dendrobatidis (Bd), is commonly transmitted through a free-swimming zoospore stage that may be vulnerable to predation. Potential predators of Bd include freshwater zooplankton that graze on organisms in the water column. We tested the ability…
  • A novel sample preparation method that enables nucleic acid analysis from ultrathin sections. [Journal Article]
    Microsc Microanal. 2013 Jun; 19(3):635-41.Klink VP, Thibaudeau G, Altig R
  • The ability to isolate and perform nucleic acid analyses of individual cells is critical to studying the development of various cell types and structures. We present a novel biological sample preparation method developed for laser capture microdissection-assisted nucleic acid analysis of ultrathin cell/tissue sections. We used cells of the mitotic bed of the tadpole teeth of Lithobates sphenoceph…
