Establishing death in stranded Odontocetes (toothed whales) using other mammals : a pilot study : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Zoology at Massey University [PDF]

open access: yes, 2003
The aim of this study was to investigate and evaluate a new method for determining death in stranded odontocetes (toothed whales). The new method was using the pulsations seen in the retinal blood vessels in the place of the heart rate. The retinal blood

Biogeography and taxonomy of extinct and endangered monk seals illuminated by ancient DNA and skull morphology [PDF]

open access: yes, 2014
Extinctions and declines of large marine vertebrates have major ecological impacts and are of critical concern in marine environments. The Caribbean monk seal, Monachus tropicalis, last definitively reported in 1952, was one of the few marine mammal ...

Beyond Serology: A Meta‐Analysis of Advancements in Molecular Detection of Brucella spp. in Seronegative Animals and Biological Samples

open access: yesVeterinary Medicine and Science, Volume 11, Issue 1, January 2025.
Molecular diagnostics, such as PCR and biosensor‐based techniques, offer high sensitivity in detecting Brucella spp. in seronegative animals, overcoming the limitations of traditional serological methods. The pooled detection rate of 35.08% suggests a substantial number of hidden carriers.

Characterization of pinniped vibrissal type and number

open access: yesMarine Mammal Science, Volume 41, Issue 1, January 2025.
Abstract Pinnipeds have vibrissae with which they can explore their environment. Two vibrissal parameters that differ in pinnipeds are shape and number. Regarding shape, most phocids have undulated vibrissae, whereas the vibrissae of a few phocids, all otariids and walruses are smooth.

Changes in the foraging strategy of female South American sea lions (Carnivora: Pinnipedia) after parturition. [PDF]

open access: yes, 2012
This study tests the hypothesis that female South American sea lions shift from off-shore, pelagic prey to coastal, benthic prey after parturition in order to reduce the foraging trip duration and hence the time pups remain unattended on the beach during

Of flippers and wings: The locomotor environment as a driver of the evolution of forelimb morphological diversity in mammals

open access: yesFunctional Ecology, Volume 38, Issue 10, Page 2231-2246, October 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The early diversification of tetrapods into terrestrial environments involved adaptations of their locomotor apparatus that allowed for weight support and propulsion on heterogeneous surfaces.

Is dirofilariosis an emerging conservation threat in wild carnivores across the Palearctic?

open access: yesMammal Review, Volume 54, Issue 4, Page 427-440, October 2024.
Phylogenetic distribution of Dirofilaria immitis and Dirofilaria repens infection in Palearctic Carnivora species. Abstract Dirofilaria species are mosquito‐borne filarial nematodes, with a high veterinary and public health importance, but growing evidence also indicates their frequent occurrence in wildlife.
