Some Tuco‐Tucos Hide More Than Others: An Integrative Approach Reveals Cryptic Diversity in Ctenomys (Rodentia: Ctenomyidae) From Central Argentina

open access: yesIntegrative Zoology, EarlyView.
Here, we adopt an integrative framework (molecular phylogenetics and geometric morphometrics) to reassess patterns of diversity and differentiation across this region. We analyzed cytochrome b sequences and quantified cranial shape variation. Our analyses indicate the presence of three species groups (mendocinus, talarum, and tucumanus) and two ...

Mapping diversity through geographical, environmental and attribute spaces

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Understanding biodiversity patterns requires integrating information across the interrelated dimensions that organize life. Species occupy specific regions in geographic space, respond to environmental conditions and vary within attribute (or trait) spaces that are shaped by their ecological and evolutionary histories.

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

open access: yesAnimal 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 ...

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

open access: yesConservation 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 ...
