Prediction of pregnancy following transfer of in‐vitro produced embryos using recipient health records, accelerometer sensors and meteorological data in Australian dairy cows

Australian Veterinary Journal, EarlyView.
Embryo transfer (ET) in dairy cattle has long been used for the dissemination of elite genetics. However, achieving consistently high pregnancy rates remains a major challenge, particularly in high‐producing lactating dairy cows receiving in‐vitro produced (IVP) embryos.

Why Social Egg Freezing for Single Women Should Not Be Prohibited: A Confucian Perspective

Bioethics, EarlyView.
ABSTRACT Beginning with a recent high‐profile case in mainland China, this paper argues that the current prohibition on social egg freezing for single women cannot be justified from a Confucian ethical perspective. We first explain why Confucian ethics provides a normatively appropriate and socially salient framework for evaluating reproductive policy ...

Pubertal Dynamics of Sertoli and Leydig Cell Dysfunction in Klinefelter Syndrome

Clinical Endocrinology, EarlyView.
ABSTRACT Context Klinefelter syndrome (KS), defined by a 47, XXY karyotype, is commonly associated with progressive testicular failure. The precise timing of Sertoli and Leydig cell dysfunction during puberty remains unclear. Objective To determine the onset and progression of testicular insufficiency during puberty in KS, and to assess whether ...

Larval character evolution in Holometabola (Insecta)

Cladistics, EarlyView.
Abstract Larvae, a novel type of immature stage, are a crucial innovation of the Holometabola. Larval features therefore provide key evidence for reconstructing evolutionary transformations in this megadiverse group. Here we present the first formal reconstruction of larval character evolution, using maximum parsimony and Bayesian ancestral‐state ...

Genomics‐informed management of ex situ populations

Conservation Biology, EarlyView.
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

The Effect of Familiarity Among Social Partners on the Jumping Behavior of Amazon Mollies

Ethology, EarlyView.
Pairs of familiar or nonfamiliar clonal Amazon mollies were tested in individual bowls, from which they could only escape from by jumping. Familiar pairs remained together significantly more than non‐familiar ones. Other behavioral aspects, such as timing and direction of jumps was not affected by familiarity.
