Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

Ibis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Critical tipping points in dung beetle communities: Implications for conservation in the Atlantic Forest biome

Insect Conservation and Diversity, EarlyView.
Minor land‐use changes consistently lead to abrupt biodiversity shifts across all diversity dimensions, favoring generalist dung beetle species while excluding sensitive specialists. These shifts are observed at lower environmental change rates than previously considered, with significant changes apparent after just 25% habitat loss.

Commercial clays in cosmetic formulations for hair care: Characterization and application to improve the mechanical properties of hair fibre

International Journal of Cosmetic Science, EarlyView.
The shampoo and conditioner bar formulations enhanced hair gloss, promoting softness, improved cuticle alignment, and effective protection of hair shafts against external aggressors. Findings from mechanical properties measurements indicate that the clay‐containing formulations enhance the mechanical strength of hair, contributing to stronger and more ...

Stayability in the Era of Early‐Challenged Females: Genetic Parameters and Correlations With Economically Relevant Traits

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study aimed to estimate the variance components, heritabilities and genetic correlations between four new different categories of stayability (STAY48‐2, STAY48‐3, STAY54‐2, STAY54‐3) with weight at 240 days of age (W240), weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at puberty in males (APM ...
