Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

Australian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

Weaponry Investment in the Socially Monogamous Snapping Shrimp Alpheus brasileiro (Decapoda: Alpheidae)

Acta Zoologica, EarlyView.
ABSTRACT Weapons are morphological structures used by animals in various contexts, especially in intra‐specific contests and visual displays. In snapping shrimps of the genus Alpheus, particularly the monogamous species Alpheus brasileiro, both sexes bear enlarged chelipeds, potentially conferring advantages in mate competition or territorial defence ...
