The moon is known for its tidal effects. But its light also can exert a powerful influence on animals large and small.
Excessive groundwater use could push more than half of the regions that depend on water pumped up from underground aquifers past an environmental tipping point by 2050. That could threaten aquatic ecosystems around the world.
Bits of plastic pollution in the ground caused earthworms to lose weight. That could hurt the worms’ ability to make soil healthy, and may explain why plants were stunted.
Wetlands are land areas that are flooded with water some or all of the time. They’re more than just wet, though. They filter water, shelter young animals and much more.
Plants and animals are moving toward the poles, changing timing of important events and more — all in response to climate change.
Citizen scientists can help with climate and conservation research by counting birds, taking pictures of flowers and deciphering old weather records.
A new survey of life on Earth finds that plants and microbes dominate. But even though humans are in the minority, they still play a major role.
When sea ice goes missing in the Arctic, every part of the ecosystem feels the effects.
Mud from Antarctica’s Lake Mercer surprised scientists with what appeared to be the carcasses of tiny animals. A neighboring lake had only microbes.
