Handling mean–variance scaling in intraspecific trait variability and implications for trait–environment analyses

Methods in Ecology and Evolution, EarlyView.
Abstract Trait‐based ecology increasingly relies on measures of intraspecific trait variability to estimate how trait diversity within species varies across species and environmental gradients. Yet variance and related metrics are often interpreted without considering their intrinsic dependence on the mean, as described by the empirical Taylor's power ...

Balancing Fire Regimes and Population Dynamics for the Conservation of a Microendemic Lizard From a Biodiversity Hotspot

Animal Conservation, EarlyView.
Disturbance from fire mediates a potential ecophysiological trade‐off between adult performance and juvenile recruitment in the microendemic lizard Ameivula jalapensis. While open, burned habitats enhance adult thermoregulation and condition, unburned patches remain critical for juvenile thermal optima.

The Bidirectional Association Between MASLD and Male Hypogonadism: An Updated Meta‐Analysis

Andrology, EarlyView.
ABSTRACT Background Metabolic dysfunction‐associated steatotic liver disease (MASLD) and male hypogonadism are increasingly prevalent, metabolically interrelated conditions. Testosterone (T) deficiency has been implicated in hepatic lipid dysregulation, insulin resistance, and visceral adiposity, whereas MASLD may impair the hypothalamic–pituitary ...

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.

Functional Morphology of the Thoracic Limb in the Silky Anteater (Cyclopes didactylus): A Comparative Study With Tamandua tetradactyla

Acta Zoologica, EarlyView.
ABSTRACT The order Xenarthra presents unique morphophysiological adaptations related to its specialized ecological niches. This study investigates the functional morphology and comparative myology of the thoracic limb in Cyclopes didactylus (silky anteater) and Tamandua tetradactyla (southern tamandua) to elucidate how muscle arrangements support ...
