Movement Patterns And Catch-And-Release Impacts Of Striped Bass In A Tidal Coastal Embayment In Massachusetts, Heather M. Tyrrell
Movement Patterns And Catch-And-Release Impacts Of Striped Bass In A Tidal Coastal Embayment In Massachusetts, Heather M. Tyrrell
Masters Theses 1911 - February 2014
An investigation into the spatial ecology and effects of catch-and-release angling on the physiology and behavior of striped bass was conducted. Fine-scale behavior was assessed by tagging fish with acoustic transmitters equipped with pressure and tri-axial accelerometer sensors and tracking them within a fixed array (n=34 receivers) in a Massachusetts estuary. Activity space changed significantly over the course of the season and increased with water temperature. Striped bass most frequently exhibited low levels of locomotory activity representing 67% of total activity measurements, with occasional high activity and burst swimming, often within the upper 3 m of the water column. Depth …
Movement Patterns Of Brook Trout In A Restored Coastal Stream System In Southern Massachusetts, Erin L. Snook
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 …
Population Size, Habitat Use And Diet Of Kittlitz's Murrelets In Prince William Sound, Alaska, Andrew J. Allyn
Population Size, Habitat Use And Diet Of Kittlitz's Murrelets In Prince William Sound, Alaska, Andrew J. Allyn
Masters Theses 1911 - February 2014
During the summer of 2008 and 2009, we studied the ecology of the Kittlitz’s Murrelet (Brachyramphus brevirostris), a small diving seabird and candidate for the U.S. Endangered Species List, in Prince William Sound (PWS), Alaska. At-sea survey data suggests that the population significantly increased from 2001 to 2009, however there is limited evidence of reproductive success. Habitat use models showed individuals were observed in shallower waters, closer to glaciers, the shoreline, and further from moraines than the available habitat during the daytime. Finer extent sampling from 2008 suggests temperature-depth profiles also influence Kittlitz’s Murrelet daytime habitat use. The …
Population Dynamics, Chick Diet, And Foraging Behavior Of The Razorbill (Alca Torda) At Matinicus Rock, Maine, Katherine E. Kauffman
Population Dynamics, Chick Diet, And Foraging Behavior Of The Razorbill (Alca Torda) At Matinicus Rock, Maine, Katherine E. Kauffman
Masters Theses 1911 - February 2014
During the summers of 2007-2009, I studied the population growth and reproductive and foraging ecology of the Razorbill (Alca torda) at Matinicus Rock (MR), Maine. This medium-sized marine bird in the family Alcidae (auks) was extirpated from the Gulf of Maine in the late 19th century by hunting, collecting, and colony disturbance. Following legislation protecting seabirds and their nesting habitats, the Razorbill has recolonized probable former nesting habitat in the Gulf of Maine during the past several decades. Six small colonies comprise the Maine population, which is listed as threatened and forms the southern extension of the …
