Spontaneous rhythms in a harbor seal pup calls [PDF]
BMC Research Notes, 2018 Objectives Timing and rhythm (i.e. temporal structure) are crucial, though historically neglected, dimensions of animal communication. When investigating these in non-human animals, it is often difficult to balance experimental control and ecological ...

Novel B19-like parvovirus in the brain of a harbor seal. [PDF]
PLoS ONE, 2013 Using random PCR in combination with next-generation sequencing, a novel parvovirus was detected in the brain of a young harbor seal (Phoca vitulina) with chronic non-suppurative meningo-encephalitis that was rehabilitated at the Seal Rehabilitation and ...

A novel harbor seal whiskers optimization algorithm
Alexandria Engineering Journal, 2023 A novel optimization algorithm, namely Harbor Seal Whiskers Optimization Algorithm (HSWOA) is proposed in this work. Harbor seals use their whiskers to find underwater disturbances which are in the form of oscillating spheres and track prey even though ...

A harbor seal (Phoca vitulina) shows extensive respiratory control in sound production [PDF]
BMC Ecology and EvolutionThe duration of animal vocalizations varies between and within species. Which mammals can learn to control this duration? Such respiratory production learning is a scarcely studied subcomponent of vocal learning.

The Pacific harbor seal gut microbiota in Mexico: Its relationship with diet and functional inferences. [PDF]
PLoS ONE, 2019 Diet is a primary driver of the composition of gut microbiota and is considered one of the main routes of microbial colonization. Prey identification is fundamental for correlating the diet with the presence of particular microbial groups.

Fine-scale variability in harbor seal foraging behavior. [PDF]
PLoS ONE, 2014 Understanding the variability of foraging behavior within a population of predators is important for determining their role in the ecosystem and how they may respond to future ecosystem changes. However, such variability has seldom been studied in harbor

Diving Related Changes in the Blood Oxygen Stores of Rehabilitating Harbor Seal Pups (Phoca vitulina). [PDF]
PLoS ONE, 2015 Harbor seal (Phoca vitulina) pups begin diving within hours of birth, stimulating the development of the blood oxygen (O2) stores necessary to sustain underwater aerobic metabolism.

Rising competition among North Sea mammalian top predators: a multi-method perspective on trophic ecology [PDF]
Scientific ReportsTop predators are crucial in shaping ecosystem dynamics by regulating key processes such as prey populations, energy transfer, and community structure, particularly in systems where multiple species compete for the same resources.

Dose-response relationships in gene expression profiles in a harbor seal B lymphoma cell line exposed to 17α-ethinyl estradiol [PDF]
Journal of Xenobiotics, 2017 The determination of changes in gene expression profiles with xenobiotic dose will allow identifying biomarkers and modes of toxicant action. The harbor seal (Phoca vitulina) 11B7501 B lymphoma cell line was exposed to 1, 10, 100, 1000, 10,000, or 25,000
