Humans may be accelerating the rate at which organic matter decomposes in rivers and streams on a global scale, according to a new study. That could pose a threat to biodiversity in waterways around the world and increase the amount of carbon in Earth's atmosphere, potentially exacerbating climate change. The study is the first to combine a global experiment and predictive modeling to illustrate how human impacts to waterways may contribute to the global climate crisis.

A new model reassesses the proportion of terrestrial and marine species threatened with extinction by climate change. While the forecasts of traditional models estimate that the diversity of terrestrial species in tropical areas could decrease by 54% between now and 2041-2060, this model is more moderate, predicting a decrease of 39%. Nevertheless, this proportion remains alarming and confirms the importance of taking urgent measures to mitigate climate change and its impact on biodiversity.

Using ancient DNA extracted from the toe bone of a museum specimen, biologists have sequenced the genome of an extinct, flightless bird called the little bush moa, shedding light into an unknown corner of avian genetic history. The work is the first complete genetic map of the turkey-sized bird whose distant living cousins include the ostrich, emu, and kiwi.

According to a paper, climate and weather predictions of increased rainfall will lead to an exponential expansion of land-locked lakes on the Tibetan Plateau, resulting in major land loss and related economic, environmental and climatic impacts.

To achieve global biodiversity targets, conservationists and governments must prioritize the establishment and effective management of large, interconnected protected areas with high ecological integrity, researchers argue in a new essay.

The diversity and ecological functionality of bird communities in tropical agroforestry systems are shaped by the surrounding landscape, in particular the extent and composition of the forest.

Scientists discover 'zoned development' in dinosaur skin, with zones of reptile-style scales and zones of bird-like skin with feathers. A new dinosaur skin fossil has been found to be composed of silica -- the same as glass.

A recent boom in the purple sea urchin population off the southern Oregon Coast appears to have had an indirect and negative impact on the gray whales that usually forage in the region, a new study shows.

The study's findings show mergansers arrived in the New Zealand region at least seven million years ago from the Northern Hemisphere, in a separate colonisation event to that which led to the Brazilian merganser.
