Herbivore Diversity Helps Maintain Arctic Tundra Diversity
A long-term experiment in southwestern Greenland reveals that the presence of musk oxen and caribou helps stave off declines in Arctic tundra diversity brought on by climate change.
When the Woods Get Noisy, the Animals Get Nervous
New study uses trail cameras and speakers to isolate what human sounds do to animals.
Mapping Beaver Dams with Machine Learning
A new model deploys a neural network to spot beavers’ engineering exploits in aerial and satellite imagery, an approach that should aid studies of ecosystem and landscape change.
Veterinary Antibiotics Reduce Soil Carbon Sequestration Capacity
Livestock grazing areas sequester less carbon than those under wild herbivores.
Making Sense of the Great Barrier Reef’s Mysterious Green Donuts
Researchers set sail to the Great Barrier Reef to study how ring-shaped algae deposits formed and evolved, what feeds them, and the diversity of creatures that call them home.
Munching Moose Cool Forest Floors
By making clear-cut forests patchier, moose create a reflective surface that bounces back sunlight and keeps temperatures down.
Ants Aren’t Adapting to Warmer Temperatures
Foraging in hotter-than-desired temperatures could negatively affect ants’ biology and the forest ecosystems that they support.
喷气推进的被囊动物在海洋碳循环中的作用
新研究表明,广泛分布的胶质浮游动物的大量繁殖,连同它们的粪便、每日的垂直迁移和它们的尸体一起,增加了海洋的碳输出。
