Too many male animals in zoos could hamper conservation of endangered species, warn scientists

The largest-ever study of over 2.6 million zoo birth records reveals skewed sex ratios in endangered species, from lemurs to elephants. The international team of scientists behind the study emphasise that it is vital that zoos take into account the ratios of males to females born in captivity when planning conservation projects and breeding programmes for endangered species to avoid the silent threat of having too many of one sex.

Mechanistic Insights into Feline Hypertrophic Cardiomyopathy: Pathway Analysis Highlights Age and Sex Differences

This article summarizes a study investigating molecular mechanisms in feline hypertrophic cardiomyopathy (HCM) via pathway analysis of cardiomyocyte markers. The study highlights age-related declines in gene expression, increased marker levels in HCM-affected cats, and significant sex differences with males showing higher expression. Findings emphasize continuous myocardial adaptation and the role of age and sex in disease pathogenesis. Keywords include feline HCM, cardiomyocyte gene expression, age and sex in cat heart disease, and molecular pathogenesis of feline cardiomyopathy.

Cat Brains Age Like Humans: Pet Cats as Natural Models for Human Aging

Understanding how aging progresses across species is crucial for advancing research into age-related diseases and developing effective treatments. However, identifying animal models that age in ways closely comparable to humans—especially reaching equivalent advanced ages—has remained a challenge.
