A Tale of Appendages: Investigating Limb and Tail Variation in Salamanders

Integrative Zoology, EarlyView.
We analyzed limb and tail proportions in 44% of known salamander species using a phylogenetic comparative approach. Our results revealed significant variation among families and ecological groups, with aquatic species showing longer limbs and basal lineages having shorter tails.

Uncovering the Process of Sexual Segregation: Male Early‐Life Individual Tactics Shape Its Onset and Affect Phenotypic Quality in a Large Mammal

Integrative Zoology, EarlyView.
Early‐life traits significantly influence sexual segregation patterns and phenotypic quality in male fallow deer. Males in better condition and those more risk‐prone left natal groups earlier with fewer returns to natal groups. However, males with frequent excursions back to natal groups compensated for initial body condition disadvantages.

The Wonder Years: A Demographic Approach to Revisit the Age‐at‐Size Conundrum in Amphibians

Integrative Zoology, EarlyView.
We combined repeated body size measurements of marked individuals of unknown age throughout their adult life with growth records of individuals marked as postmetamorphic juveniles and recaptured years later as sexually mature adults, focusing on 10 amphibian species in central Spain.

BirdNET: Automated Detection for Monitoring Critically Endangered Lemurs from the Maromizaha Forest

Integrative Zoology, EarlyView.
In this study, we evaluated the effectiveness of integrating PAM with BirdNET, a convolutional neural network originally developed for avian vocalization detection, to monitor two critically endangered lemurs, Indri indri and Varecia variegata, in Madagascar's Maromizaha rainforest.

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

Integrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.
