Marine Mammals Before Extirpation: Using Archaeology To Understand Native American Use Of Sea Otters And Whales in Oregon Prior to European Contact
… while others, such as the locally extinct Oregon sea otter, never recovered. Threats from hunting are past, but marine mammals on the Northwest Coast today face new challenges, and sea otters and cetaceans are foci of conservation efforts. Despite the interest these taxa enjoy in the present, …

Swimming sentinels : climate clues from stranded marine mammals
From skinny sea lions on beaches in California, to hundreds of enormous dead whales in the fjords of Chile, scientists have been recently puzzled by a spate of dead and dying marine mammals. These events are so complicated- influenced by disease, biotoxins, ecosystem changes, and human …

Problem solving and tool use in three species of otter
Sea otters are well known tool users, yet the cognitive capacities of other otter species have been sparsely studied. Precedent exists for non-tool using species closely related to native tool users to display comparable abilities under experimental conditions. The social intelligence hypothesis …

Structure, function and context : the impact of morphometry and ecology on olfactory sensitivity
… tested. The sensitivity of a marine mammal, the sea otter (Enhydra lutris) was measured in order to determine whether a marine lifestyle results in impaired olfaction. The effect of dietary relevance on sensitivity to specific odorants was evaluated. Finally, a new morphometric model of olfactory …

Evaluating Recruitment Seasonality of Red Abalone (<i>Haliotis Rufescens</i>) to Inform Fisheries Management and Conservation Policy
… declines since the 1960s due to overfishing, disease, and climatic factors. Thus, understanding population dynamics to inform management and population restoration is critical. Recruitment dynamics of red abalone are poorly understood, with no prior knowledge of seasonal trends. To address this …

Pismo Clams (Tivela stultorum) in Califorina: Population Status, Habitat Associations, Reproduction, and Growth
… to human harvest and predation by California sea otters (<em>Enhydra lutris</em>); However, no studies have examined their populations, population drivers, or life history for at least 40 years. Managers require updated and expanded information on populations, habitat associations, …
