CANADA

Although caribou populations are declining across most of the Canadian wilderness, research suggests British Columbia’s Klinse-Za herd has tripled in size in nine years. Two First Nations groups are responsible for protecting the herd.

ECUADOR

Researchers described two new-to-science species of glass frog–tiny, transparent amphibians living in the Andes foothills. The genomes of these two species are surprising, despite being almost identical and living on opposite sides a river valley.

SCOTLAND

New analysis of the famous “bodies in the bog” found near Edinburgh indicates that at least two–a man and a woman–were born far from their final resting place. To determine whether they were Medieval ramblers, scientists used chemical isotopes found in the teeth of the individuals.

RWANDA

Scientists in Nyungwe National Park recently captured a Hill’s horseshoe bat, a species last spotted by scientists in 1981. Researchers recorded the bat’s call to monitor its population and released it before it was released.

SPAIN

Archaeologists studying Paleolithic cave art in Cantabria found that up to a quarter of the ochre handprints placed there were made by children. These prints were probably made by blowing red pigment through hollow reeds or bone on top of a stenciled hand.

TANZANIA

A program on the semiautonomous islands of Zanzibar combines drones and a smartphone app to map malaria-carrying mosquito hotspots. The mosquitoes breed in tiny bodies of standing water, which are difficult to survey on foot–but one drone can cover more than 70 acres in about 20 minutes.
