Steller sea lions (Eumetopias jubatus) of Oregon and Northern California: seasonal haulout abundance patterns, movements of marked juveniles, and effects of hot-iron branding on apparent survival of pups at Rogue Reef

Creator:: Scordino, Jonathan
Abstract:: The Steller Sea Lion Research Initiative was passed in 2001 to provide funding to help scientists determine causes and solutions for the population crash of Steller sea lions (Eumetopias jubatus). In response to need to understand population dynamics of Steller sea lions, NOAA Fisheries has spearheaded a large-scale, range-wide research...

Low Diversity in theMitogenome of Sperm Whales Revealed by Next-Generation Sequencing

Creator:: Alexander, Alana, Steel, Debbie, Slikas, Beth, Hoekzema, Kendra, Carraher, Colm, Parks, Matthew, Cronn, Richard, and Baker, C. Scott
Abstract:: Large population sizes and global distributions generally associate with high mitochondrial DNA control region (CR) diversity. The sperm whale (Physeter macrocephalus) is an exception, showing low CR diversity relative to other cetaceans; however, diversity levels throughout the remainder of the sperm whale mitogenome are unknown. We sequenced 20 mitogenomes from...

Pool habitat characteristics and juvenile anadromous salmonids in two Oregon coastal streams

Creator:: Haapala, Deborah L.
Abstract:: Relations between the diversity of juvenile anadromous salmonids and pool features were examined in a managed and a pristine watershed in Oregon during the summer of 1990. There were no differences (p>0.05) in pool depth, velocity or pool wood volumes between streams. However, the pristine system had twice the number...

A whale's tale of mtDNA diversity and differentiation : the Antarctic blue whale

Creator:: Sremba, Angela L.
Abstract:: Twentieth century commercial whaling drastically reduced the abundance of great whale populations in the Southern Ocean. Exploitation began on the south Atlantic island of South Georgia, where catch records account for over 175,000 whales killed. Modern whaling within the Southern Ocean depleted populations rapidly, and by 1966, hunting blue whales...

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...

Temporal Variation in Humpback Whale (Megaptera novaeangliae) Demographics Along the Western Antarctic Peninsula

Creator:: Pallin, Logan J.
Abstract:: Humpback whale populations in Antarctica are recovering after intensecommercial whaling in the 20th century. Along the Western Antarctic Peninsula (WAP)this recovery is occurring in an environment that is experiencing the fastest warming ofany region on the planet. To begin to understand the dynamics of this recovery undersuch dramatic climate change,...

The influence of local fidelity and recruitment on population dynamics and specialized foraging of humpback whales in Glacier Bay and Icy Strait, Alaska

Creator:: Pierszalowski, Sophie Penny
Abstract:: Humpback whales (Megaptera novaeangliae, Borowski 1781) in the North Pacific migrate from mid- to high- latitude summer feeding grounds along the Pacific Rim, including areas off the coasts of the U.S., Canada, Russia and eastern Asia, to tropical breeding grounds each winter along Pacific coasts of Mexico and Central America...

Humpback whales (Megaptera novaeangliae) in the South Pacific breeding grounds : an allocation from feeding areas and an abundance estimate of whales specific to French Polynesia waters

Creator:: Gibb, Giselle Renee
Abstract:: South Pacific humpback whales were devastated by commercial whaling in their Antarctic feeding areas during the 20th century. Understanding migratory connections and current abundance of these isolated breeding stocks is crucial for the allocation of historical Antarctic catches in population dynamic models used to assess current recovery. However, only a...

Proximity to multiple foraging habitats enhances seabirds’ resilience to local food shortages

Creator:: Paredes, Rosana, Harding, Ann M. A., Irons, David B., Roby, Daniel D., Suryan, Robert M., Orben, Rachael A., Renner, Heather, Young, Rebecca, and Kitaysky, Alexander
Abstract:: As central-place foragers, seabirds from colonies located close to multiple and/or productive marine habitats might experience increased foraging opportunities and enhanced resilience to food shortages. We tested whether this hypothesis might explain divergent trends in 3 populations of black-legged kittiwakes Rissa tridactyla, a surface-feeding piscivore, in the eastern Bering Sea....
