Sea otter health: Challenging a pet hypothesis
A recent series of studies on tagged sea otters (Enhydra lutris nereis) challenges the hypothesis that sea otters are sentinels of a dirty ocean, in particular, that pet cats are the main source of exposure to Toxoplasma gondii in central California. Counter to expectations, sea otters from unpopulated stretches of coastline are less healthy and more exposed to parasites than city-associated ot...
متن کاملAutomated Extraction of Archaeological Traces by a Modified Variance Analysis
This paper considers the problem of detecting archaeological traces in digital aerial images by analyzing the pixel variance over regions around selected points. In order to decide if a point belongs to an archaeological trace or not, its surrounding regions are considered. The one-way ANalysis Of VAriance (ANOVA) is applied several times to detect the differences among these regions; in partic...
متن کاملThe Genome of the Northern Sea Otter (Enhydra lutris kenyoni)
The northern sea otter inhabits coastal waters of the northern Pacific Ocean and is the largest member of the Mustelidae family. DNA sequencing methods that utilize microfluidic partitioned and non-partitioned library construction were used to establish the sea otter genome. The final assembly provided 2.426 Gbp of highly contiguous assembled genomic sequences with a scaffold N50 length of over...
متن کاملSarcocystis neurona retinochoroiditis in a sea otter (Enhydra lutris kenyoni).
Sarcocystis neurona is an important cause of fatal disease in sea otters in the USA. Encephalitis is the predominant lesion and parasites are confined to the central nervous system and muscles. Here we report retinochoroiditis in a sea otter (Enhydra lutris kenyoni) found dead on Copalis Beach, WA, USA. Salient lesions were confined to the brain and eye. Multifocal nonsuppurative meningoencepha...
متن کاملPatterns in sea otter resource selection in Kachemak Bay, Alaska
Sea otters (Enhydra lutris) are known to forage extensively in both rocky and soft-bottom habitats throughout their range in Alaska. Their ability to significantly reduce prey abundance, limit prey size, and consequently alter community structure has been well documented. Much of this research, however, has focused on sea otter interactions with rocky habitats and associated epifaunal invertebr...
