DOI: 10.1016/j.cub.2018.05.022
Abstract: Virtually all land mammals and birds have two sleep states: slow-wave sleep (SWS) and rapid eye movement (REM) sleep [1, 2]. After deprivation of REM sleep by repeated awakenings, mammals increase REM sleep time [3],… read more here.

DOI: 10.1016/j.pocean.2019.102220
Abstract: Abstract From fall 2013 through 2015, a large-scale, multi-year warm water anomaly occurred in the northeast Pacific Ocean. The phenomenon had negative impacts on some oceanic predators, including higher mortalities and poor body conditions. We… read more here.

DOI: 10.1038/s41598-021-93253-1
Abstract: Tracking studies of juveniles are rare compared to those of adults, and consequently little is known about the influence of intrinsic and extrinsic factors on activity during this critical life stage. We used hourly GPS… read more here.

DOI: 10.1177/0300985816677151
Abstract: Tissues of South American fur seal pups naturally infected with hookworms (Uncinaria sp) were examined. Hookworm infection was found in nearly all pups examined (132/140, 94%), and hookworm enteritis with secondary bacteremia was considered the… read more here.

DOI: 10.1371/journal.pone.0265610
Abstract: Fur seal populations in the Southern Hemisphere were plundered in the late 1700s and early 1800s to provide fur for a clothing industry. Millions of seals were killed resulting in potentially major ecosystem changes across… read more here.

DOI: 10.3354/dao03073
Abstract: The relatively small population size and restricted distribution of the Guadalupe fur seal Arctocephalus townsendi could make it highly vulnerable to infectious diseases. We performed a colony-level assessment in this species of the prevalence and… read more here.
