Knowing which direction to go in order to reach a food location or home is important for many animal species, including humans. For human foragers who travel long distances every day hunting and gathering, orientation skills are essential. Haneul Jang and her colleagues from the Max Planck Institute for Evolutionary Anthropology set out to study … Read more
Just as humans are usually left- or right-handed, other species sometimes prefer one appendage, or eye, over the other. A new study reveals that American robins that preferentially use one eye significantly more than the other when looking at their own clutch of eggs are also more likely to detect, and reject, a foreign egg … Read more
Climate change can threaten species and extinctions can impact ecosystem health. It is therefore of vital importance to assess to which degree animals can respond to changing environmental conditions – for example by shifting the timing of breeding – and whether these shifts enable the persistence of populations in the long run. To answer these … Read more
Tourists on safari can provide wildlife monitoring data comparable to traditional surveying methods, suggests research appearing July 22 in the journal Current Biology. The researchers analyzed 25,000 photographs from 26 tour groups to survey the population densities of five top predators (lions, leopards, cheetahs, spotted hyenas, and wild dogs) in northern Botswana, making it one of … Read more
Described in 1981, the genus Biswamoyopterus is regarded as the most mysterious and rarest amongst all flying squirrels. It comprises two large (1.4-1.8 kg) species endemic to southern Asia: the Namdapha flying squirrel (India) and the Laotian giant flying squirrel (Lao PDR). Each is only known from a single specimen discovered in 1981 and 2013, … Read more
The microscopic protists Rhodelphis limneticus and Rhodelphis marinus are genetically ‘sisters’ to red algae, but couldn’t be more different. Red algae are fleshy, large organisms with a simple genome that perform photosynthesis, just like plants. Rhodelphis are single-cell predators with a large, complex genome. The two protists have a chloroplast, though it is not photosynthetic anymore, pointing to their close ties … Read more
In previous studies, males have been found to kill when females will not mate with them if they are still caring for an offspring sired by their previous partner. Dieter Lukas and Elise Huchard have now looked into infanticide by female mammals. “Across mammals, females are more likely to commit infanticide when conditions are harsh … Read more
Africa has new purple-clad warriors more than 200 feet beneath the ocean’s surface. Deep-diving scientists from the California Academy of Sciences’ Hope for Reefs initiative and the University of Sydney spotted dazzling fairy wrasses – previously unknown to science – in the dimly lit mesophotic coral reefs of eastern Zanzibar, off the coast of Tanzania. The multicolored … Read more
Crouching in the boot-sucking mud of the Baylands Nature Preserve in Palo Alto, Manu Prakash, associate professor of bioengineering at Stanford University, peered through his Foldscope – a $1.75 origami microscope of his own invention – scrutinizing the inhabitants of the marsh’s brackish waters. With his eye trained on a large single-cell organism, called Spirostomum, he watched it do something … Read more
Gorillas have more complex social structures than previously thought, from lifetime bonds forged between distant relations, to “social tiers” with striking parallels to traditional human societies, according to a new study. The findings suggest that the origins of our own social systems stretch back to the common ancestor of humans and gorillas, rather than arising … Read more
