Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans

Integrative Zoology, EarlyView.
An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.

Gonadal Development–Related Genes and a Male‐Specific Genetic Marker Identified in the Endangered Sichuan Taimen (Hucho bleekeri)

Integrative Zoology, EarlyView.
Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

Comparative Genomics and Functional Evidence for Convergent Adaptation to Hypoxia in Mammals

Integrative Zoology, EarlyView.
This study reveals convergent selection in mammals adapted to hypoxia. Functional assays demonstrate that amino acid mutations reduce oxidative stress, attenuate hypoxia‐induced injury, and modulate the hypoxia‐inducible transcription factor (HIF)‐driven hypoxic response.

Contrastive ecoacoustic indices: Large‐scale global soundscape characterization with contrastive inference

Methods in Ecology and Evolution, EarlyView.
Abstract Ecoacoustics mainly aims at monitoring soundscapes by means of non‐invasive protocols. Despite the widespread adoption of machine and deep learning techniques, existing ecoacoustic models predominantly rely on supervised learning and, consequently, face two primary limitations: (1) the necessity of annotated data; and (2) the restriction to ...

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 ...
