    • Accuracy Assessment of Skeletochronology in the Arizona Tiger Salamander (Ambystoma tigrinum nebulosum) 

      Eden, Christopher J.; Whiteman, Howard H.; Duobinis-Gray, Leon; Wissinger, Scott A. (American Society of Ichthyologists and Herpetologists (ASIH), 2007-05-16)
      Skeletochronology is the most commonly used tool for evaluating the age of amphibians and reptiles. However, the accuracy of skeletochronology is questionable because few studies have utilized individuals of known age to ...
    • Amphibian Populations Cycles and Long-Term Data Sets 

      Wissinger, Scott A.; Whiteman, Howard H. (University Of California Press, 2005-01-01)
      Although most researchers agree that many amphibian populations are declining, there is debate about how to distinguish human-induced declines from natural population fluctuations. As with many species, amphibian populations ...
    • Exposure to corticosterone affects host, but not tolerance, to an emerging fungal pathogen. 

      Murone, Julie; DeMarchi, Joseph A.; Venesky, Matthew D. (Public Library of Science, 2016-09-30)
      Host responses to pathogens include defenses that reduce infection burden (i.e., resistance) and traits that reduce the fitness consequences of an infection (i.e., tolerance). Resistance and tolerance are affected by an ...
    • An interaction between climate change and infectious disease drove widespread amphibian declines 

      Cohen, Jeremy M.; Civitello, David J.; Venesky, Matthew D.; McMahon, Taegan A.; Rohr, Jason R. (Wiley, 2018-11-28)
      Climate change might drive species declines by altering species interactions, such as host–parasite interactions. However, few studies have combined experiments, field data, and historical climate records to provide evidence ...
    • Temporal shift of diet in alternative cannibalistic morphs of the tiger salamander 

      Denoël, Mathieu; Whiteman, Howard H.; Wissinger, Scott A. (Linnean Society of London, 2006-01-15)
      Evolutionary theory predicts that alternative trophic morphologies are adaptive because they allow a broad use of resources in heterogeneous environments. The development of a cannibal morphology is expected to result in ...
    • The thermal mismatch hypothesis explains host susceptibility to an emerging infectious disease 

      Venesky, Matthew D.; Cohen, Jeremy M.; Civitello, David J.; Rohr, Jason R.; Sauer, Erin L.; McMahon, Taegan A.; Roznik, Elizabeth A. (John Wiley & Sons, 2017-02)
      Parasites typically have broader thermal limits than hosts, so large performance gaps between pathogens and their cold- and warm-adapted hosts should occur at relatively warm and cold temperatures, respectively. We tested ...
    • Wetland Animal Ecology 

      Batzer, Darold P.; Cooper, Robert; Wissinger, Scott A.; Sharitz, Rebecca R. (University of California Press, 2016)
