Species Distribution Models Reveal the Resilience of Protected Areas for Conserving an Endemic Amazonian Canid

Animal Conservation, EarlyView.
This graphical abstract illustrates the impacts of climate change on the distribution of the Amazon‐endemic canid Atelocynus microtis, highlighting projected habitat loss under future scenarios (SSP2–4.5 and SSP5–8.5). Despite substantial reductions in suitable habitat, a significant proportion remains within Protected Areas, emphasizing their critical

Hidden Losses: Assessing the Risk of Coextinction Among Ectoparasitic Flies and Their Bat Host Species in Brazil

Animal Conservation, EarlyView.
The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).

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 ...

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.
