Some animals help fight climate change by boosting the amount of carbon dioxide that plants, algae and bacteria absorb from the atmosphere.
Pollutants that build up in night air can break down the scents that attract pollinating hawkmoths to primrose blooms, disrupting their pollination.
Called lianas,these vines are growing out of control. They may cause tropical forests to absorb less carbon dioxide — worsening climate change.
A vast swath of ocean surrounds Antarctica, hidden under the ice. Here, strange creatures burrow into the dark underbelly of a floating glacier.
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.
