Assessing Seasonal Changes In Body Condition For Spotted (Phoca Largha), Ringed (Pusa Hispida), And Bearded (Erignathus Barbatus) Seals, Michelle Hartwick
Assessing Seasonal Changes In Body Condition For Spotted (Phoca Largha), Ringed (Pusa Hispida), And Bearded (Erignathus Barbatus) Seals, Michelle Hartwick
Master's Theses
Anthropogenic global warming is causing unprecedented changes to occur within Arctic ecosystems. As sea ice continues to decline in both thickness and extent, ice-adapted species will be particularly affected. Specifically, Arctic seals are reliant on sea ice during critical life-history stages and many of their preferred prey depend on reliable patterns in annual sea ice cover. Thus, ongoing changes will likely affect the ability of Arctic seals to carry out key life-history tasks and maintain positive energy balance. One way to assess energy reserves is through examination of body condition. For seals, this is often done by measuring overall blubber …
Assessing Methods For Determining Reference Conditions For Riparian Restoration In Santa Clara County, Claire Mallen
Assessing Methods For Determining Reference Conditions For Riparian Restoration In Santa Clara County, Claire Mallen
Master's Theses
Valley Water is the primary water wholesaler and flood control agency in Santa Clara County, providing services to 1.9 million residents. The operation and maintenance of infrastructure for water supply and flood control often require work within legally protected natural resources such as riparian ecosystems. Riparian ecosystems are dynamic and diverse ecosystems that provide our society with valuable services such as wildlife habitat, water quality, and recreation. However, the threat of human development on native ecosystems has led to the degradation and loss of 85-98% of riparian ecosystems nationwide. Today, federal, state, and regional laws mitigate further impacts to riparian …
Evaluating Methods To Reduce Humpback Whale (Megaptera Novaeamgliae) Ship Strike Mortality In Nearshore Feeding Habitats Within The San Francisco Bay, Alisa Keenan
Master's Theses
Across our world’s oceans, whales are perpetually stuck and killed by large ships. Sea-based commercial trade is increasing on a global scale; therefore, more large ships are circumnavigating through biologically important whale habitats. This is of grave concern to marine resource managers, especially in the United States where major shipping corridors overlap critical whale habitat. It is feared that in these areas with high whale density, ship strikes are reducing populations of whales to levels below what is sustainable for threatened and endangered species, thereby hindering the recovery of depleted whale populations. Humpback whales, a species that is federally-listed as …
