Sexual dimorphism and ancestral variation in the pectoral and pelvic girdles of modern humans
Homo, 2023 Discussions of the evolution of sexual dimorphism in torso shape and the pectoral region assume that this dimorphism exists independently of body size.

Stable isotopes reveal differences in diet among reed bunting subspecies that vary in bill size [PDF]
, 2016 Reed bunting Emberiza schoeniclus subspecies vary considerably in bill size and shape and seem to be at an early stage of speciation, in which bill might be indirectly causing reproductive isolation.

Sexual dimorphism in cancer [PDF]
Nature Reviews Cancer, 2016 The incidence of many types of cancer arising in organs with non-reproductive functions is significantly higher in male populations than in female populations, with associated differences in survival. Occupational and/or behavioural factors are well-known underlying determinants.

Respiratory‐Limbic Coupling via a Thalamic Circuit Alleviates Anxiety
Advanced Science, EarlyView.This study delineates a conserved preBötCGlu→PVT→CeA circuit that gates anxiety and respiration. Activation of this circuit is anxiolytic and respiratory‐stabilizing, while its inhibition has the opposite effect. Mechanistically, PVT exerts its anxiolytic action via a disinhibitory microcircuit: its inputs preferentially target CeL GABAergic neurons ...

Sexual Dimorphism in Fin Size and Shape in North American Killifish
Ecology and EvolutionSexual dimorphism is intriguing because it suggests that males and females differ in phenotypic optima for traits and that sex‐specific trait values can evolve despite a shared genome.

Acta Herpetologica, 2021 Intersexual morphological differences within a species occur in many traits, including body size and shape. Many processes that cause geographic variability in morphology have been proposed: population structure, phenotypic plasticity (environmental ...

Advanced Science, EarlyView.Our study identifies selenium deficiency as a hallmark of MASH pathogenesis. Dietary selenium supplementation enhances hepatic fatty acid oxidation (FAO) and attenuates MASH progression by activating the PPARα pathway via selenoprotein H (SELENOH). This selenium‐SELENOH‐PPARα nexus redefines the functional scope of selenoproteins, moving from redox ...

Are there sex differences in the body size of the Eurasian red squirrel in Slovakia? [PDF]
, 2015 Sexual dimorphism of the Eurasian red squirrel on five somatic variables (head-and-body length, tail length, hind foot length, ear length and body weight) was evaluated on 55 squirrels.

Sexual dimorphism in dinosaurs
eLife, 2023 Studying fossils from a mass-mortality event reveals evidence for sexual dimorphism and, unusually, equal numbers of males and females in a herd of dinosaurs.
