Occurrence and distribution of sarcoptic mange in wild Neotropical canids
Sarcoptic mange affects most Neotropical canid species across multiple countries. It represents a widespread yet largely overlooked conservation threat with potential for cross‐species transmission. Coordinated monitoring and management efforts are needed to understand and mitigate its impacts. Abstract Sarcoptic mange, a contagious skin disease caused

ABSTRACT This study investigated the effects of season and environmental disturbances on fish communities in neotropical rivers of the Sorocaba basin, a Sub‐Basin of the Paraná River in Southeast Brazil, based on sampling 1196 individuals from 49 species, including two non‐native and one threatened with extinction.

Beyond Occurrence: Evidence Gaps for Non‐Native Freshwater Fishes in Brazilian Drylands
ABSTRACT Non‐native freshwater fishes are widely reported in inland waters, but occurrence records are often interpreted together with stronger evidence of establishment, reproduction, spread, pathways and impacts. This can overstate what published records support, especially in regions where reservoirs, river‐basin transfers and artificial ...

We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Comparative Analysis of Correlative Modeling Methods in Predicting North American Bird Abundance
This study compares nine ecological niche model (ENM) methods to predict North American bird abundance and finds positive correlations between environmental suitability and abundance. Results highlight the potential of ENMs for abundance inference, with newer methods showing good performance and demonstrating that simpler data inputs can be effective ...

Testing the Dry Refuge Model: Paleoecological Insights From Late Pleistocene Gomphotheres in Ecuador
We present paleontological evidence that may prove the Dry Refuge Model in Ecuador during the Late Pleistocene. ABSTRACT Paleoenvironmental records indicate that Neotropical regions near the Equator experienced reduced rainfall during the Last Glacial Maximum (LGM). However, some records show conflicting environmental signals.

We synthesized 360 studies on environmental heterogeneity (EH) across taxa, regions, and disciplines. Only 10% of studies explicitly defined EH, and definitions were predominantly descriptive. We identify four operational interpretations of EH and propose a Research Roadmap linking EH metrics to five mechanistic hypotheses with testable predictions ...

Homology of the branchiostegals rays in atherinomorph fishes demonstrated by the position of the rays relative to the interhyoideus muscle. In beloniform outgroups, above, the two groups of branchiostegal rays are separated by the interhyoideus. In beloniform fishes, below, only one group of branchiostegal rays is present.
