An Assessment Of Environmental Dna As A Tool To Detect Fish Species In Headwater Streams, Stephen F. Jane
An Assessment Of Environmental Dna As A Tool To Detect Fish Species In Headwater Streams, Stephen F. Jane
Masters Theses 1911 - February 2014
Recent years have seen an explosion of interest in the use of freely available DNA present in aquatic systems, otherwise known as environmental DNA (eDNA), as a tool for monitoring aquatic organisms. However, much remains unknown about the behavior of eDNA over a range of environmental conditions. This is particularly true in high gradient headwater streams, which have received less attention than other types of water bodies. In the summer of 2011, a headwater stream system with well established species distributions was sampled using eDNA techniques. Though species were detected where known to be present, detections also occurred where traditional …

Movement Patterns Of Brook Trout In A Restored Coastal Stream System In Southern Massachusetts, Erin L. Snook
Masters Theses 1911 - February 2014
Populations of anadromous brook trout can be found from northern Canada into New England. It is believed that the extent of anadromy exhibited by coastal brook trout populations decreases with latitude, but the ecology and movements of the more southern populations are less studied. A 33-month acoustic telemetry study of anadromous brook trout (Salvelinus fontinalis) was conducted in a restored coastal stream and adjacent marine system in southeastern Massachusetts. Movement and migration patterns of 54 brook trout were investigated for individual differences and common features. Individuals exhibited a range of movement patterns. Some were more resident and only …
