Circumpolar Diversity and Geographic Differentiation of mtDNA in the Critically Endangered Antarctic Blue Whale (Balaenoptera musculus intermedia)

Creator:: Sremba, Angela L., Hancock-Hanser, Brittany, Branch, Trevor A., LeDuc, Rick L., and Baker, C. Scott
Abstract:: The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using...

Population Differentiation in two Northeastern Pacific Marine Species

Creator:: Curran, Lorne Sullivan
Abstract:: Population genetic techniques are now preeminent in differentiating wild populations. Natural resource managers rely on them in their efforts to restore viable populations of fish and wildlife. Overfishing adversely impacted Yelloweye Rockfish (Sebastes ruberrimus) on the U.S. West Coast in the late 20th century. Management actions included shutting down the...

Big fishery, big data, and little crabs: Using genomic methods to examine the seasonal recruitment patterns of early life stage Dungeness crab (Cancer magister) in the California Current Ecosystem

Creator:: Lee, Elizabeth M. J. and O'Malley, Kathleen G.
Abstract:: The California Current Ecosystem (CCE) is a dynamic marine ecosystem from which many socioeconomically important fisheries species are harvested. Here, a genotyping- by-sequencing (GBS) approach was used to examine genomic variation in an early life stage (megalopae) of the Dungeness crab (Cancer magister), which constitutes the most valuable single-species commercial...

An Investigation into the Distribution, Residency Patterns, Population Connectivity, and Abundance of Blue Whales (Balaenoptera musculus) in New Zealand

Creator:: Barlow, Dawn R.
Abstract:: Species conservation depends on robust population assessment. Data on population abundance, distribution, and connectivity are critical for effective management, especially as baseline information for newly documented populations. I describe a pygmy blue whale (Balaenoptera musculus brevicauda) population in New Zealand waters with year-round presence that overlaps with industrial activities. This...

Spatial and temporal scales of genetic change in two overfished rockfishes

Creator:: Gomez-Uchida, Daniel
Abstract:: Pacific rockfishes (genus Sebastes) have attracted wide scientific and public interest from an evolutionary, fishery and conservation standpoints. This dissertation addresses several hypotheses involving spatial and temporal scales of genetic change in two overfished rockfishes, darkblotched (S. crameri) and canary rockfish (S. pinniger), using statistical analyses of genetic variation within...

Small mammal and bird abundance in relation to post-fire habitat succession in mountain big sagebrush (Artemisia tridentata ssp. vaseyana) communities

Creator:: Holmes, Aaron L.
Abstract:: Fire is an important disturbance mechanism in big sagebrush (Artemisia tridentata) communities, yet little is known about wildlife population dynamics during post-fire habitat succession. I estimated the abundance of small mammals and birds in relation to fire history in mountain big sagebrush (A.t. spp. vaseyana) communities on the Sheldon National...

Creator:: Hughes, Robert M., Amezcua, Felipe, Chambers, David M., Daniel, Wesley M., Franks, James S., Franzin, William, MacDonald, Donald, Merriam, Eric, Neall, George, dos Santos Pompeu, Paulo, Reynolds, Lou, and Woody, Carol Ann
Abstract:: Following a four-year period of writing, member comment, and multiple revisions, the AFS Position Paper and Policy on Mining and Fossil Fuel Extraction was approved unanimously by the membership at the Society's annual business meeting August 19, 2015, in Portland, Oregon. The entire document can be read at fisheries.org/policy_statements; a...

Mercury bioaccumulation in remote subalpine lakes : assessing the influence of invasive trout on salamanders

Creator:: Pfleeger, Adam
Abstract:: Mercury (Hg) contamination is a global conservation threat to freshwater ecosystems, detected in even the protected lakes of Olympic National Park (Washington, USA). Although considered some of the most remote and pristine US ecosystems, these lakes are currently subject to multiple environmental stressors, including climate change and fish introductions; adding...

Effects of Habitat Characteristics, Weather and Presence of Barred Owls (Strix varia) on Occupancy Dynamics and Breeding Propensity of Northern Spotted Owls (S. occidentalis caurina) in Mount Rainier National Park

Creator:: Mangan, Anna O.
Abstract:: For over 100 years, National Parks have existed to preserve America’s natural and cultural heritage for current and future generations. As environmental pressures on wildlife and habitats have increased in recent decades, National Park lands have become important protected areas for many threatened and endangered species. Conservation and management of...

Interactive influences of wildfire and nonnative species on plant community succession in Hawaii Volcanoes National Park

Creator:: Ainsworth, Alison
Abstract:: The role of fire as a natural disturbance, its interactions with nonnative species and effects of repeated fires in the Hawaiian Islands have received little investigation. We are unsure of the role fire played in shaping forest structure and composition as well as affecting evolutionary processes of the native biota....
