Published Uncovering plant invasions in the tropics
(via sciencedaily.com) An international collaboration of scientists has created the first inventory of flora introduced to the tropics, filling a knowledge gap about invasive plants in the tropics.
Published Discovery of world's oldest DNA breaks record by one million years
(via sciencedaily.com) Two-million-year-old DNA has been identified -- opening a 'game-changing' new chapter in the history of evolution. Microscopic fragments of environmental DNA were found in Ice Age sediment in northern Greenland. Using cutting-edge technology, researchers discovered the fragments are one million years older than the previous record for DNA sampled from a Siberian mammoth bone. The ancient DNA has been used to map a two-million-year-old ecosystem which weathered extreme climate change.
Published Dinosaurs were on the up before asteroid downfall
(via sciencedaily.com) Dinosaurs dominated the world right up until a deadly asteroid hit the earth, leading to their mass extinction, some 66 million years ago, a landmark study reveals. Fresh insights into dinosaurs' ecosystems -- the habitats and food types that supported their lives -- suggests that their environments were robust and thriving, right up until that fateful day, at the end of the Cretaceous period.
Published Rhino conservation in Nepal creates a burden for communities, infrastructure and other species, study warns
(via sciencedaily.com) Efforts to conserve rhinos in Nepal have put a burden on communities, infrastructure and other wildlife in Nepal, a new study warns.
Published New research shows people, wildlife, and marine environment benefit when island-ocean connections are restored
(via sciencedaily.com) A new perspective shows that linking land and sea through coordinated conservation efforts may offer unrealized and amplified benefits for biodiversity, human wellbeing, climate resilience and ocean health, and provides a microcosm for the untapped potential of ecosystem restoration on a larger scale.
Published Large terrestrial mammals are more vulnerable to the acoustic impact of drones than to the visual impact, study finds
(via sciencedaily.com) Original source Large terrestrial mammals are vulnerable to the acoustic sounds of drones, technological systems which are increasingly used to study the wildlife in open habitats such as the savanna and marshes, according to a new study.
Published Mammoth problem with extinction timeline
(via sciencedaily.com) Original source Paleontologists say environmental DNA is not always helpful in identifying when animals like mammoths went extinct because genetic material found in sediment could have come from animals that died thousands of years earlier.
