Genetic variability in Guadalupe fur seals.
The Guadalupe fur seal (Arctocephalus townsendi) population underwent one or two severe bottlenecks due to commercial sealing in the late 19th century. Since then the protected population has been growing steadily around their only rookery, Isla de Guadalupe, Mexico. We probed both nuclear and mitochondrial genomes using multilocus nuclear DNA profiling and mitochondrial DNA sequencing to estim...
متن کاملPrehistoric Marine Mammal Overki l l in the Northeastern Pacific: A Review of New Evidence
Prehistoric exploitation of marine mammals in the northeastern Pacific has been a subject of considerable attention since 1992 when Hildebrandt and Jones used an optimal foraging model to argue that when congregated in rookeries, seals and sea lions represent highly attractive resources vulnerable to overpredation. Using archaeofaunal data from sites along the Oregon and California coasts they ...
متن کاملImpact of the 2015 El Niño-Southern Oscillation on the Abundance and Foraging Habits of Guadalupe Fur Seals and California Sea Lions from the San Benito Archipelago, Mexico.
The abundance of California sea lions (Zalophus californianus) (CSLs) and Guadalupe fur seals (Arctocephalus philippii townsendi) (GFSs) from the San Benito Archipelago (SBA) was determined through nine monthly surveys in 2014-2015. Assessment of their foraging habits was examined based on the isotopic analysis of pups (maternal indicators) (SIAR/SIBER-R). Environmental variability between 2014...
متن کاملMetagenomic Survey of Viral Diversity Obtained from Feces of Subantarctic and South American Fur Seals
The Brazilian South coast seasonally hosts numerous marine species, observed particularly during winter months. Some animals, including fur seals, are found dead or debilitated along the shore and may harbor potential pathogens within their microbiota. In the present study, a metagenomic approach was performed to evaluate the viral diversity in feces of fur seals found deceased along the coast ...
متن کاملON THE PRESENCE OF A VAGRANT JUAN FERNÁNDEZ FUR SEAL (Arctocephalus philippii) IN THE PACIFIC COAST OF COLOMBIA: A NEW EXTRALIMITAL RECORD
We report the first record of a male Juan Fernández fur seal, Arctocephalus philippii (Peters, 1866), in the Colombian Pacific coast. The animal was mainly identified according to the external morphology of the head and snout. This observation is the first northernmost record for A. philippii in the Southeastern Pacific, with an extreme movement covering a total distance of approximately 3700-4...
