A new online tool reveals how more than 200 planned dams worldwide will alter river temperatures, potentially rendering waters too hot or too cold for native fish.
Understanding when and where trees die in vast tropical forests is a challenging first step toward understanding carbon dynamics and climate change.
The field of animal ecology has entered the era of big data and the Internet of Things.
