Each tail flap uses less than half as much energy than swimming solo, making it easier for fish to catch their breath after an underwater sprint.
This environmental DNA can aid in conserving species that are hard or dangerous to observe.
Giant kelp are at risk due to climate change and human activities. In New Zealand, a community effort is rebuilding these underwater algal forests.
Although many of the world's forests have gotten less fragmented since 2000, tropical forests have gotten more chopped up, putting animals at risk.
Challenges from human-caused climate change, deforestation and degradation leave the fate of this vast forest uncertain.
Ecological relationships between predators and their prey drive the evolution of plants, animals and microbes.
All the species in an ecosystem and the feeding relationships between them get summed up with this handy picture.
Marine ecosystems may have been back in action just a million years after the most severe extinction event known.
Wildfires are so important for many ecosystems that sometimes professionals set them on purpose.
