Animals lose fear of predators rapidly after they start encountering humans

Most wild animals show a suite of predator avoidance behaviors such as vigilance, freezing, and fleeing. But these are quickly reduced after the animals come into contact with humans through captivity, domestication, or urbanization, according to a new study.

Wild birds as offerings to the Egyptian gods

Millions of mummified ibis and birds of prey, sacrificed to the Egyptian gods Horus, Ra or Thoth, have been discovered in the necropolises of the Nile Valley. Such a quantity of mummified birds raises the question of their origin: were they bred, like cats, or were they hunted? According to a team of scientists that carried out extensive geochemical analyses on mummies, they were wild birds.

Fungi in a warmer world

(Northumbria University ) Scientists from universities in the UK, US and Argentina are joining forces in a $1m research project to discover what impact an increase in global temperatures could have on the millions of species of fungi around the world.

40% of O’ahu, Hawai’i beaches could be lost by mid-century

The reactive and piecemeal approach historically used to manage beaches in Hawai’i has failed to protect them. If policies are not changed, as much as 40% of all beaches on O’ahu, Hawai’i could be lost before mid-century, according to a new study.

Male baboons with female friends live longer

Opposite-sex friendships can have non-romantic benefits. And not just for people, but for our primate cousins, too. A 35-year study of 542 baboons finds that males that have close female friends have higher rates of survival. Previous studies have assumed that males befriend females to protect their offspring, or to boost their chances of mating later on. But the new study points to an additional benefit: female friends may help them live a longer life.

Australia Declares its Largest Feral Predator-Free Safe Haven – in Massive Mallee Cliffs National Park

Just in time for September and Biodiversity Month, conservationists in Australia announced they have eradicated all feral cats and foxes from a vast 9,570-hectare area, creating the largest feral predator-free safe haven on the country’s mainland. This, in turn, paves the way for the largest re-wilding project ever to be undertaken in the state of […]

Like humans, chimpanzees can suffer for life if orphaned before adulthood

A new study shows that orphaned male chimpanzees are less competitive and have fewer offspring of their own than those who continue to live with their mothers. The remaining puzzle is, what is it that their mothers provide that keeps chimpanzees healthy and competitive?

How researchers look at the bird brain in action

How do birds make decisions and which brain regions are particularly active when they solve tasks? Researchers are investigating these questions. So far, only anesthetized birds and therefore passive experiments could be examined using the functional magnetic resonance imaging (fMRI). Thus, the examination of brain processes during active tasks was not possible. Now the researchers have constructed an experimental set-up which allows them to carry out fMRI examinations on awake pigeons and thus also investigate cognitive processes for the first time.
