Population Level Responses To Direct Application Liming In Gyrinophilus Porphyriticus, Shelby Renea Timm Jan 2015

Population Level Responses To Direct Application Liming In Gyrinophilus Porphyriticus, Shelby Renea Timm

Theses, Dissertations and Capstones

Direct application liming (DAL) has been used to neutralize acidified streams to restore aquatic biota. This mitigation technique has been used globally for decades, yet little data exist on its effects on amphibian populations. My study investigated the effects of liming on amphibians by measuring variability in life histories of larval Gyrinophilus porphyriticus. I collected larvae from six streams in the Monongahela National Forest, West Virginia. I examined the effects of DAL on age structure, and I failed to detect a treatment effect. I used ANCOVAs to examine differences in body condition, body size, and gape size. I observed that …
