Now there are about 3,000 otters in California and sea otters are protected as a threatened species under the Endangered Species Act. The Giant Otter features a very long body, similar to that of a weasel. Giant otter with supper. The findings have implications for the conservation of rare and endangered species, in which low genetic diversity could increase the odds of extinction.Genetic diversity is a measure of how many differences exist across the genome among individuals in a population. I've seen this with neotropical river otters and giant otters as well, not just our North American variety. You cannot keep one as a pet in the US. The otters form social groups to help maintain control of their territories and to protect one another.

Giant river otters are very sociable and live in families of between 3 – 10 individuals that hunt together. This decline is largely due to habitat loss and commercial fur hunting. These genes are present across mammal species, but sea otters seem to have changes in these genes that may have benefitted them during their evolution, the researchers concluded.Beichman, Wayne, Lohmueller and colleagues are currently conducting a follow-up study to sequence the 20,000 genes in 130 other sea otters from populations around the north Pacific Rim, including the Kuril Islands north of Japan, the Aleutian Islands, central Alaska and Baja California, Mexico.The research was funded by the National Science Foundation, the Monterey Bay Aquarium, a National Institutes of Health Training Grant in genomic analysis and interpretation, UCLA's Academic Senate and the UCLA Catalyst Program.The complete list of co-authors may be found in the journal article.Lake Superior island wolves are close to extinctionDespite their low genetic diversity, sea otters are fairly healthy and do not show obvious deformities.

She and her colleagues reconstructed the otter's evolutionary history and assessed its level of genetic diversity, history of changes in its population size, and levels of potentially harmful genetic variation.The biologists found evidence of potentially harmful genetic variation and of mating between closely related ancestors in the sea otter genome -- a pattern that is common in endangered species with small population sizes. Common river otters are not that large. I, too, assumed that sea + otter = sea otter. Here’s why. The marine otter is larger than the Eurasian Otter.

Large populations tend to have high genetic diversity (many differences among individuals), while small populations lose much of this diversity, resulting in individuals that are more genetically similar to one another.The sea otter's low level of genetic diversity is similar to endangered species, such as the cheetah and Tasmanian devil, said lead author Annabel Beichman, a UCLA graduate student in ecology and evolutionary biology.

Groups with as many as 20 individuals have been reported, but groups of 4 to 8 are more common. Many people find this particular Otter to be different in size and shape from others. "We found that Isle Royale wolf genomes harbor characteristic signatures of recent inbreeding, causing large tracts of the genome to be devoid of genetic diversity," said Robinson, lead author of the study.

Sea otters also have thick, brown fur that insulates them against the cold waters of the Pacific Ocean. "Sea otter populations crashed and we wanted to study the effects that had on its genome, as well as the effects of its marine environment on its genome," said co-senior author Kirk Lohmueller, UCLA associate professor of ecology and evolutionary biology, and of human genetics.The biologists found evidence of small changes in a set of nine genes that cumulatively are implicated in the evolution of the thick fur of the otters.

"While low diversity isn't necessarily dangerous by itself, we also found elevated levels of potentially harmful variation within genes, possibly due to a history of population declines -- which could impact the population going forward," Beichman said.
