Ants hold grudges, study suggests

A team of evolutionary biologists has demonstrated that ants learn from experience. Led by Dr. Volker Nehring, research associate in the Evolutionary Biology and Animal Ecology group at the University of Freiburg, and doctoral ...

Invasive tilapia species threaten Gulf of Carpentaria ecosystems

A new study led by Griffith University has tracked two invasive fish species—the Mozambique and spotted tilapia—and found them established in the Mitchell River catchment in Northern Queensland, which flows into the Gulf ...

New orchid found on Australian island resembles a cupcake

Imagine discovering a tiny orchid perched on a tree branch in a forest. It resembles an orchid you've seen before, but something is subtly different. Could it be a new species that hasn't yet been named or described by science?

19 times a day: Male medaka mating limits revealed

Working out the kinks of mating in the animal kingdom helps to gain insights into the survival of species. Among animals that have multiple partners who deposit eggs outside their body, such as most fish, the males release ...

Why some birds choose to divorce while others mate for life

Relationship dynamics among birds can be just as complex as they are in humans. While some bird species stick with one partner for life, new research has shown others might switch partners after just one breeding season.

Your stress levels also affect your dog, heart rate study shows

Dogs have lived alongside humans for thousands of years. They have been used to hunt, guard, herd and perform many other tasks, but today they mainly act as companions. While their lives today may seem easy compared with ...

Spiders 'smell' with their legs, new research finds

Spiders have always lived alongside humans, so it's surprising how much we still don't know about them. One long-standing mystery was related to how spiders detect smells. Now, our latest research has finally uncovered the ...

Bighorn sheep face death by avalanche in Sierra Nevada range

Snow cover in the Sierra Nevada is expected to shrink overall as the climate warms, but avalanche frequency could remain the same or even increase at high elevations. That's bad news for bighorn sheep that live there, according ...

Exploring the biomechanics of rose prickles with advanced imaging

It is said that every rose has its thorn, but technically speaking, roses have prickles. Prickles are derived from the epidermis of the plant, whereas true thorns are modified stems. Rose prickles defend the plant from herbivores ...
