These elephants remained solitary or associated in mixed-age and mixed-sex groups within the forested areas.

Environmental and anthropogenic factors have not just degraded elephant habitats and left them stressed, but also changed their social behaviour, notes a recent study conducted by the National Institute of Advanced Studies (NIAS), Bengaluru.

The savanna is not an easy place to live, even for African elephants, the largest land animals on earth. If it's a challenge for these 7,000-pound giants, what's it like for their newborn babies?

Elephant extinction in the Congo basin could accelerate climate change by allowing 7% more greenhouse gases into the atmosphere, according to a study published in Nature Geoscience.

This would mean an extra 3 billion tons of harmful carbon entering the atmosphere, lead researcher Fabio Berzaghi told The Independent.

A thrilling journey into the minds of African elephants as they struggle to survive.
If, as many recent nonfiction bestsellers have revealed, animals possess emotions and awareness, they must also have stories. In "The White Bone," a novel imagined entirely from the perspective of African elephants, Barbara Gowdy creates a world whole and separate that yet illuminates our own.

The discovery could have implications for trophy hunters, who target the biggest and oldest bulls.

Measuring 10 feet tall at the shoulder and weighing over 6 tons, Matt the African savanna elephant is one of the largest land animals on Earth. And though the pachyderm is as old as 52, he still puts an incredible amount of energy into mating.

Elephant trunks derive power and finesse by simulating bone joints

Submitted by Naturenomics Team on Tue, 25/06/2019 - 10:04

Researchers find that an elephant’s trunk forms a kind of joint to pick up small pieces of food, a technique they say could be used as inspiration for robotic arms.

A team of researchers led by Jianing Wu at the Georgia Institute of Technology, Georgia, USA, videoed an African elephant (Loxodonta africana) eating small pieces of food and measured the force its trunk exerted throughout the exercise. They found that the animal swept the food into piles and then formed a joint to pick up as much as possible at once.
