As Arctic warms, caribou and muskoxen slow biodiversity loss
Diversity declined by about 0.85 species per decade when herbivores were excluded, whereas this decline was only about 0.33 species per decade when they were allowed to graze. The scientists attributed this to herbivores keeping species such as shrubs, dwarf birch and gray willow in check so that other plants could better flourish.

Rare butterflies thriving after reintroduction bid
The large heath butterfly was once so widespread that it was locally named the Manchester argus. But its habitat was wrecked by the 19th Century arrival of the Liverpool and Manchester Railway. Wildlife experts said they were "optimistic" about the species, which is now "breeding strongly".

We’ve pumped so much groundwater that we’ve nudged the Earth’s spin, says new study
By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the Earth tilted nearly 80 centimeters (31.5 inches) east between 1993 and 2010 alone, according to a new study published in Geophysical Research Letters.

How traditional Indigenous education helped four lost children survive 40 days in the Amazon jungle
Indigenous children typically learn from an early age how to open paths through dense vegetation, how to tell edible from non-edible fruits. They know how to find potable water, build rain shelters and set animal traps. They can identify animal footprints and scents—and avoid predators such as jaguars and snakes lurking in the woods.

Urban great tits less stressed than their countryside cousins, finds study
"The great tit's high cognitive capacity means it is highly adaptable, and urban great tits seem to have adapted so well to the new environment that they are not stressed by high population density. Another possible explanation is that it was the most intelligent and most flexible individuals who succeeded in colonizing urban environments in the first place," says Anders Brodin, biologist at Lund University.

Climate change has increased diversity of butterflies in Sweden and Finland, may have major ecosystem consequences
New research shows that butterflies have expanded their ranges over the past 120 years to cope with a warmer climate in Sweden and Finland. Although driven by a warmer climate, range expansions have also been influenced by human land use and vary according to species thermal tolerances and habitat preferences.
