A satellite-linked tag for the long-term monitoring of diving behavior in large whales

open access: yesAnimal Biotelemetry, 2022
Despite spending most time underwater, the technology in use to track whales over large geographic ranges via satellite has been largely limited to locational data, with most applications focusing on characterizing their horizontal movements. We describe

The Mammals of Angola [PDF]

open access: yes, 2019
Scientific investigations on the mammals of Angola started over 150 years ago, but information remains scarce and scattered, with only one recent published account. Here we provide a synthesis of the mammals of Angola based on a thorough survey of primary and grey literature, as well as recent unpublished records.

How many bird and mammal extinctions has recent conservation action prevented?

open access: yesbioRxiv, 2020
Aichi Target 12 of the Convention on Biological Diversity (CBD) aims to ‘prevent extinctions of known threatened species’. To measure its success, we used a Delphi expert elicitation method to estimate the number of bird and mammal species whose ...

Coloration in Mammals

open access: yesTrends in Ecology & Evolution, 2020
Mammalian colors and color patterns are some of the most diverse and conspicuous traits found in nature and have been widely studied from genetic/developmental and evolutionary perspectives. In this review we first discuss the proximate causes underlying variation in pigment type (i.e., color) and pigment distribution (i.e., color pattern) and ...

Blood-based indicators of insulin resistance and metabolic syndrome in bottlenose dolphins (Tursiops truncatus)

open access: yesFrontiers in Endocrinology, 2013
Similar to people with metabolic syndrome, bottlenose dolphins (Tursiops truncatus) can have a sustained postprandial hyperglycemia and hyperinsulinemia, dyslipidemia, and fatty liver disease.

Body Temperature Frequency Distributions: A Tool for Assessing Thermal Performance in Endotherms?

open access: yesFrontiers in Physiology, 2021
There is increasing recognition that rather than being fully homeothermic, most endotherms display some degree of flexibility in body temperature. However, the degree to which this occurs varies widely from the relatively strict homeothermy in species ...

Inferring the mammal tree: Species-level sets of phylogenies for questions in ecology, evolution, and conservation

open access: yesPLoS Biology, 2019
Big, time-scaled phylogenies are fundamental to connecting evolutionary processes to modern biodiversity patterns. Yet inferring reliable phylogenetic trees for thousands of species involves numerous trade-offs that have limited their utility to ...

Linking spatial patterns of terrestrial herbivore community structure to trophic interactions

open access: yeseLife, 2019
Large herbivores influence ecosystem functioning via their effects on vegetation at different spatial scales. It is often overlooked that the spatial distribution of large herbivores results from their responses to interacting top-down and bottom-up ...

Mitochondrial Genomes of the United States Distribution of Gray Fox (Urocyon cinereoargenteus) Reveal a Major Phylogeographic Break at the Great Plains Suture Zone

open access: yesFrontiers in Ecology and Evolution, 2021
We examined phylogeographic structure in gray fox (Urocyon cinereoargenteus) across the United States to identify the location of secondary contact zone(s) between eastern and western lineages and investigate the possibility of additional cryptic ...
