Understanding Mammalian Habitat Use With a Multi‐Species, Multi‐Scale Approach: The Jaguar Protection Corridor in Guaviare, Colombia

Animal Conservation, EarlyView.
We applied a multi‐scale, multi‐species framework to quantify how landscape structure and human infrastructure influence habitat use across a terrestrial mammal community within a biological corridor in the Colombian Amazon. Forest cover and spatial configuration influenced wildlife habitat use at spatial scales associated with species dispersal ...

Morphology of Guard Hairs in Amazonian Marsupials: Intergeneric Variation, Habitat and Habit Association in a Phylogenetic Framework of the Order Didelphimorphia

Acta Zoologica, EarlyView.
ABSTRACT The cuticle and medulla of guard hairs exhibit distinct morphological patterns among mammalian species. To investigate this variability in marsupials from the Brazilian Amazon, we analysed guard hairs from nine Didelphimorphia species and incorporated data from an additional 25 didelphid species.

Mamíferos pequeños de humedales de la costa central del Perú

Revista Peruana de Biología, 2020
Los humedales son ecosistemas frágiles e importantes que, a pesar de su gran biodiversidad, se conoce poco sobre la diversidad de mamíferos. Por ello, en este estudio se documenta la diversidad y abundancia de los mamíferos pequeños de cuatro humedales ...

Evaluating the use of taxonomy in the IUCN Red List

Conservation Biology, EarlyView.
Abstract Taxonomy defines the units that conservationists strive to preserve for future generations. However, the discovery of new species and the taxonomic revision of existing species affect conservation efforts. Despite the importance of taxonomy for a species’ conservation, there is currently no overview of how those leading species extinction risk

Impact of global change on the distribution of mountain mammals and birds

Conservation Biology, EarlyView.
Abstract Climate change and land‐use changes are key drivers of global biodiversity loss. Many species are shifting to higher elevations or latitudes in response to global warming, often encountering unfavorable land‐use conditions during the shift. These changes can lead to reduced range size and increased extinction risks, particularly for mountain ...

Identifying hotspots of faunal data deficiency to direct urgent research and monitoring

Conservation Biology, EarlyView.
Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...

Subspecies taxonomy reflects social and geographic patterns of taxonomic effort in tetrapods

Conservation Biology, EarlyView.
Abstract Subspecies have been used in conservation biology to account for intraspecific patterns in genetic diversity, which is crucial to long‐term population viability. Although over 3200 subspecies are currently assessed by the International Union for Conservation of Nature Red List, their biological relevance remains controversial.
