Reproduction in Domestic Animals, Volume 61, Issue 6, June 2026.ABSTRACT In a stallion breeding‐soundness examination, testicular volume may be estimated either from total scrotal width or by measuring the height, width and length of both testes. This study aimed to determine whether testicular morphometric parameters obtained by ultrasonography fluctuate throughout the year, and whether these variations affect ...

Sexual selection in a transparent worm : insights from fluorescent sperm [PDF]
, 2015 Sexual selection is a potent source of selection underlying the evolution of sexual dimorphism, reproductive strategies and mating systems. Although sexual selection was initially thought to occur exclusively at the pre-copulatory stage (e.g., contests ...

Imaging and genetic toolbox to study Arabidopsis embryogenesis
New Phytologist, Volume 250, Issue 3, Page 1483-1491, May 2026.Summary Embryogenesis in the model plant Arabidopsis thaliana provides a framework for understanding how cell polarity and patterning coordinate with hormonal signalling to establish the plant body plan. Following fertilisation, the zygote divides asymmetrically to generate apical and basal lineages, establishing the apical–basal axis that defines ...

Occurrence and evolution of cannibal behaviour in extant snakes
Biological Reviews, Volume 101, Issue 2, Page 644-664, April 2026.ABSTRACT Extant snakes (Serpentes) are a highly diverse group of squamate reptiles, which have independently evolved key morphological adaptations to consume a large variety of vertebrate and invertebrate prey. While these predator–prey interactions have been widely addressed by several studies, little is known regarding the occurrence of cannibal ...

Pronounced within-individual plasticity in sperm morphometry across social environments
, 2016 Sperm morphometry (i.e., size and shape) and function are important determinants of male reproductive success and are thought to be under stabilizing selection.
