Estimating Landscape Quality And Genetic Structure Of Recovering American Marten Populations In The Northeastern United States, Cody Michael Aylward
Estimating Landscape Quality And Genetic Structure Of Recovering American Marten Populations In The Northeastern United States, Cody Michael Aylward
Graduate College Dissertations and Theses
The American marten (Martes americana) is an endangered species in Vermont and a Regional Species of Greatest Conservation Need in the northeastern United States. Though historically widespread in northeastern forests, their range presumably contracted to northern Maine and the High Peaks region of the Adirondacks by the early 1900s. Regionally, populations appear to be in recovery. Natural recolonization is believed to have occurred in New Hampshire, northeastern Vermont and the western Adirondacks. A reintroduction effort in southern Vermont that was originally declared unsuccessful is now believed to be the source of a recently detected population in the area. However, our …
Master's Project: Guiding Recreation At Travertine Hot Springs: An Environmental Assessment And Photo Monitoring Protocol, Julia Runcie
Master's Project: Guiding Recreation At Travertine Hot Springs: An Environmental Assessment And Photo Monitoring Protocol, Julia Runcie
Rubenstein School Masters Project Publications
In a remote corner of eastern California, natural hot springs deposit tawny ribbons of travertine limestone within a mosaic of sagebrush steppe, pinyon-juniper woodland, and alkali meadows. Known as Travertine Hot Springs Area of Critical Environmental Concern, these 160 acres host tens of thousands of visitors each year. Trampled vegetation, illegal campfire rings, and two and a half miles of meandering informal paths attest to the heavy use the area sustains. In partnership with the Bureau of Land Management and the Bridgeport Indian Colony, I designed a trail system, a blueprint for interpretive signage, and a suite of infrastructural enhancements …
Early Feeding In Lake Trout Fry (Salvelinus Namaycush) As A Mechanism For Ameliorating Thiamine Deficiency Complex, Carrie L. Kozel
Early Feeding In Lake Trout Fry (Salvelinus Namaycush) As A Mechanism For Ameliorating Thiamine Deficiency Complex, Carrie L. Kozel
Graduate College Dissertations and Theses
Recruitment failure of lake trout (Salvelinus namaycush) in the Great Lakes has been attributed in part to the consumption of alewife (Alosa pseudoharengus) by adult lake trout, leading to Thiamine Deficiency Complex (TDC) and early mortality in fry. The current understanding of thiamine deficiency in lake trout fry is based on information from culture and hatchery settings, which do not represent conditions fry experience in the wild and may influence the occurrence of TDC. In the wild, lake trout fry have access to zooplankton immediately following hatching; previous studies found that wild fry begin feeding before complete yolk-sac absorption. However, …
Spawning Site Selection And Fry Development Of Invasive Lake Trout In Yellowstone Lake, Yellowstone National Park, Wyoming, Lee Simard
Graduate College Dissertations and Theses
Since their discovery in Yellowstone Lake in 1994, Lake Trout (Salvelinus namaycush) have been the object of an intensive gillnet suppression program due to their predation on native Yellowstone Cutthroat Trout (Oncorhynchus clarkii bouvieri). Managers are also interested in targeting early life stages to augment suppression. A benthic sled was used to sample for Lake Trout eggs at 24 locations, hypothesized to be spawning sites, that encompassed a range of depths, slopes, and substrate composition to determine the location and characteristics of spawning sites in Yellowstone Lake. Lake Trout eggs were collected at seven sites, five of which had not …
