Divergence in heritable life history traits suggests potential for local adaptation and trade‐offs associated with a coal ash disposal site

R. Wesley Flynn, Allison M. Welch, Stacey L. Lance

Globally, human activities have resulted in rapid environmental changes that present unique challenges for wildlife. However, investigations of local adaptation in response to simultaneous exposure to multiple anthropogenic selection pressures are rare and often generate conflicting results. We used an in situ …

Naproxen and Its Phototransformation Products: Persistence and Ecotoxicity to Toad Tadpoles (Anaxyrus terrestris), Individually and in Mixtures

Wendy Cory, Allison M. Welch, Jessica N. Ramirez, Luke C. Rein

Although pharmaceutical pollution is a global environmental concern, much remains unknown about the transformation of pharmaceuticals in the wild and their effects on wildlife. In the environment, pharmaceuticals typically transform to some extent into different, structurally related compounds. Pharmaceutical transformation products resulting …

Developmental Stage Affects the Consequences of Transient Salinity Exposure in Toad Tadpoles

Allison M. Welch, Jordan P Bralley, Ashlyn Q Reining, Allison M Infante

Development can play a critical role in how organisms respond to changes in the environment. Tolerance to environmental challenges can vary during ontogeny, with individual- and population-level impacts that are associated with the timing of exposure relative to the timing of vulnerability. …

Analyzing Indoor and Outdoor Heat Index Measurements in Kitchens

Allison M. Welch

Occupationally induced heat-related illnesses (HRI) can play a huge part in the lives of employees working within outdoor kitchens. According to the National Institute for Occupational Safety and Health [NIOSH] (2016), “exposure to heat can result in injuries, disease, reduced productivity and …

Assessment of interactive effects of elevated salinity and three pesticides on life history and behavior of southern toad ( Anaxyrus terrestris ) tadpoles

Liza Wood, Allison M. Welch

Because habitats are increasingly exposed to multiple stressors simultaneously, assessing the interactive effects of stressors is crucial for understanding how populations respond to human-altered habitats. Salinization of freshwater habitats is increasing and has the potential to interact with other stressors. Chemical pollutants …

A MULTIVARIATE ANALYSIS OF GENETIC VARIATION IN THE ADVERTISEMENT CALL OF THE GRAY TREEFROG,HYLA VERSICOLOR

Allison M. Welch, Michael J. Smith, H. Carl Gerhardt

Genetic variation in sexual displays is crucial for an evolutionary response to sexual selection, but can be eroded by strong selection. Identifying the magnitude and sources of additive genetic variance underlying sexually selected traits is thus an important issue in evolutionary biology. …
