Mini-Mouse is a bad mom

A team of scientists at the University of Rochester Medical Center discovered that mice without the TR4 gene are born smaller, less fertile, and have poor parenting skills. The miniature mice exhibit reduced nest-building, nursing, and offspring care, resulting in high pup mortality rates.

Multi-species herbivore outbreak follows El Niño drought in Panama

A multi-species herbivore outbreak occurred in Panama following an El Niño drought, causing moth larvae to devour 250% more leaf material than usual. The short-lived event was brought under control quickly by natural predators and diseases, but highlights the potential impact of climate change on forest ecosystems.
