Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

The life history strategy of a fur seal hookworm in relation to pathogenicity and host health status

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2018
The strategies that parasites use to exploit their hosts can lead to adverse effects on human and animal populations. Here, we describe the life cycle, epidemiology, and consequences of hookworm (Uncinaria sp.) disease in South American fur seals ...

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

open access: yesMarine 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 ...

Ontogenetic dietary changes in male South American fur seals Arctocephalus australis in Patagonia [PDF]

open access: yesMarine Ecology Progress Series, 2015
This study assessed ontogenetic dietary changes in male South American fur seals Arctocephalus australis in northern and central Patagonia (Argentina) using stable isotope ratios (δ 15 N and δ 13 C) in vibrissae and bones. Sucking pups were characterised by higher δ 15 N values and lower δ 13 C values than older specimens. Weaning was associated with a

Recovery of donor meadows of posidonia sinuosa and posidonia australis contributes to sustainable seagrass transplantation [PDF]

open access: yes, 2012
Donor meadow recovery is important in deciding whether removal of material from natural seagrass meadows is a sustainable activity. Thus an investigation into meadow regrowth was undertaken as part of a large-scale seagrass rehabilitation effort in ...
