Pharmaceutical pollution can significantly affect wild animal behaviour, including speeding up salmon migration.
Despite dutiful toad patrols, evidence suggests that the amphibians are declining in the UK.
Researchers have been estimating the vast numbers of insects, including many pollinators, migrating at one location in the Pyrenees. But climate change and habitat loss could affect their abundance.
Climate change is exposing animals to temperatures outside of their normal limits – a new study has found that insects have a particularly weak ability to adjust.
Millions of miles of fences crisscross the Earth's surface. They divide ecosystems and affect wild species in ways that often are harmful, but are virtually unstudied.
