Amphibian Populations Cycles and Long-Term Data Sets
(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 ...
The thermal mismatch hypothesis explains host susceptibility to an emerging infectious disease
(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 ...
Exposure to corticosterone affects host, but not tolerance, to an emerging fungal pathogen.
(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 ...

Accuracy Assessment of Skeletochronology in the Arizona Tiger Salamander (Ambystoma tigrinum nebulosum)
(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 ...
Temporal shift of diet in alternative cannibalistic morphs of the tiger salamander
(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 ...
