Phylogenetic and Functional Originality Shape Species Positions in Flea–Mammal Networks Across Biogeographic Realms

open access: yesIntegrative Zoology, EarlyView.
The relationship between the position of a flea species in the networks and its functional originality was found to be consistently positive in all realms, independently of which originality index was used. ABSTRACT We investigated the relationships between a species’ network position (measured as the combined normalized degree, species strength, and ...

Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

open access: yesIntegrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

Stable Isotope Analysis as a Tool to Prevent Illicit Wildlife Trade of Songbirds in Brazil

open access: yesAnimal Conservation, EarlyView.
Feather isotopes provide clear differences between wild and captive songbirds in Brazil. Combining multiple isotopes improved classification accuracy and revealed individuals falsely declared as captive‐bred. These results demonstrate the potential of isotope analysis to detect wildlife laundering in the bird trade.

When “Rescue” Means Exile: The Urgency of Science‐Based Protocols for Large Carnivore Interactions and Coexistence in the Neotropics

open access: yesAnimal Conservation, EarlyView.
Using the recent case of an Andean jaguar translocated hundreds of kilometers to a distinct savanna ecosystem in Colombia, we critique the prevalent “Reactive Removal” model often framed misleadingly as “rescue.” We contrast this approach, which disregards local adaptation, creates ecosystem mismatches, and blocks natural range recovery, with a needed “
