Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females

Integrative Zoology, EarlyView.
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

Integrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

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.
