|A Test of Parental Preferences for Offspring Sex and Ornamentation in Eastern Bluebirds (Sialia sialis)
||Avian parents protect their fledglings from predators. Given parents have limited resources, they face trade-offs when simultaneously rearing multiple offspring. Parents might favor particularly valuable offspring. Offspring characteristics influence...
|Effects of social aggression on tree swallow (Tachycineta bicolor) offspring behavior and physiology
||Territorial animals that breed in high-density environments often experience high levels of competition for resources necessary for reproduction and, thus, are likely to engage in social aggression with conspecifics. In many species, increased social...
|Food Web Structure of a Subtropical South American Stream with Particular Focus on the Co-Evolution of Form and Function in an Endemic Species Flock
||I analyzed the food web structure of the Rio Cuareim, a subtropical piedmont stream located along the Uruguay-Brazil border. I used stable isotope ratios and stomach content analysis to delineate the trophic guild structure of fishes and invertebrate...
|Occupancy Modeling and Disease Susceptibility of Montane Salamander Species in Western North Carolina
||Amphibians worldwide are in a state of decline. Their declines could be caused by habitat destruction, chemical pollution, UV-B irradiation, exotic species, exploitation, climate change, and disease. Monitoring at-risk populations allows researcher...
|Effects of Physicochemical Parameters and Land-Use Composition on the Abundance and Occurrence of Eastern Hellbenders (Cryptobranchus alleganiensis alleganiensis)
||Altered landscapes have negative effects on stream habitats through altering hydrologic, sediment, and nutrient cycling regimes. These changes often reduce or displace populations of sensitive biota. The hellbender (Cryptobranchus alleganiensis) is a...
