Marine animals have been following their preferred climate for millions of years

Current global warming has far-reaching ecological consequences, also for the Earth’s oceans. Many marine organisms are reacting by migrating towards the poles. Researchers at Geozentrum Nordbayern at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now discovered that marine animals have been migrating for millions of years when the temperature on Earth increases or decreases.

Researchers use LiDAR to locate invasive fish and preserve a national treasure

For decades the National Park Service has been locked in a battle against lake trout, an invasive fish with a voracious appetite that has overtaken Yellowstone Lake and upended its formerly thriving ecosystem. According to new research, an aircraft-mounted instrument could offer a faster way to locate and capture the non-native fish during the brief weeks each year when they come into shallow water to spawn.

78,000-year cave record from East Africa shows early cultural innovations

An international, interdisciplinary group of scholars working along the East African coast have discovered a major cave site which records substantial activities of hunter-gatherers and later, Iron Age communities. Detailed environmental research has demonstrated that human occupations occur in a persistent tropical forest-grassland ecotone, adding new information about the habitats exploited by our species, and indicating that populations sought refuge in a relatively stable environment. Prior to this cave excavation, little information was available about the last 78,000 years from coastal East Africa, with the majority of archaeological research focused on the Rift Valley and in South Africa.
