Identification of a Novel Astrovirus in Pinnipeds

Frontiers in Microbiology, 2022
Astroviruses infect human and animals and cause diarrhea, fever, and vomiting. In severe cases, these infections may be fatal in infants and juvenile animals.

Complete Mitochondrial Genomes Recovered From Environmental Metagenomics Samples Can Facilitate Non‐Intrusive Population Genetic/Genomics Studies in the South American Sea Lion Otaria byronia

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Mitochondrial genomes assembled from environmental non‐intrusive fecal DNA to support non‐intrusive biomonitoring in the Southern Sea Lion Otaria byronia. Photograph by Nestor Galina, used with permission. ABSTRACT The abundance of many marine mammals is declining due to local, regional, and global climate stressors that characterize the Anthropocene ...

Intraspecific variation in prey quality affects the consumption rates of top predators

Journal of Animal Ecology, Volume 95, Issue 1, Page 65-83, January 2026.
This study reveals overlooked intraspecific variation in prey quality and its influence on predator energy budgets. By identifying key ecological drivers, we emphasize the need to integrate such variability into bioenergetic models to improve predictions of predator foraging and ecosystem responses to environmental change.

Mystery of the Disappearing Dogfish: Transboundary Analyses Reveal Steep Population Declines Across the Northeast Pacific With Little Evidence for Regional Redistribution

Fish and Fisheries, Volume 27, Issue 1, Page 1-12, January 2026.
ABSTRACT Quantifying broad‐scale population trends and distribution change is critical for effective management and conservation of marine species, particularly under climate change. However, fragmented regional survey data often hinder such efforts for transboundary populations. A prime example is Pacific Spiny Dogfish (Squalus suckleyi, Squalidae), a

New records of non-resident pinnipeds from the Gulf of California, Mexico Registros nuevos de pinnípedos no-residentes en el golfo de California, México

Revista Mexicana de Biodiversidad, 2010
Although the California sea lion (Zalophus californianus) is the only pinniped resident in the Gulf of California, there are occasional records of 3 additional species; here we report 4 recent records of the Guadalupe fur seal (Artocephalus townsendi), 6

Social associations between California sea lions influence the use of a novel foraging ground [PDF]

Royal Society Open Science, 2017
Social relationships define an individual's position in its social network, which can influence the acquisition and spread of information and behavioural variants through the population. Thus, when nuisance behaviours spread through wildlife populations,

Vibrissae Length as a Morphological Proxy for Foraging Behavior in Pinnipeds

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Foraging behavior is a key driver of ecological and evolutionary processes. Individual specialization can influence the behavioral flexibility of populations in response to environmental change, making it crucial to account for individual variation.

First Comprehensive Study of Telomere Length Measured by Southern Blot Hybridization and Oxidative Stress Across 12 Captive Marine Mammal Species

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Telomeres, repetitive nucleotide sequences at chromosome ends, shorten with oxidative damage and cell replication, and are increasingly used as biomarkers of stress and physiological state. Despite this potential, telomere length (TL) in marine mammals has been measured using Southern blot hybridization in only a few cases, often from ...

Diet of California sea lions, Zalophus californianus, at San Jorge Island, northern Gulf of California, Mexico, 1998–1999

Ciencias Marinas, 2005
The California sea lion, Zalophus californianus (Lesson, 1828), is the only resident pinniped in the Gulf of California, the largest populations inhabiting the Midriff islands and the northern gulf. San Jorge Island, in the northern gulf, has the second

Exploring Marine Mammal Cognition as a Conservation Tool

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Cognition is an animal's real‐time adaptation system for responding to change. Rapid environmental change, often anthropogenic, is expanding the range and severity of challenges confronting wild animals. Effective conservation requires a multifaceted approach that includes animals' capacities.
