'Whenever biodiversity decays, you decay': French biologist Marc-André Selosse
A leading environmentalist is warning that the destruction of the world's biodiversity is one of the defining challenges of our time – and one that deserves far greater public attention. Marc-André Selosse, a professor at the French National Museum of Natural History and the Univ
Not all green space is equal: New framework highlights overlooked ecological factors in na
A new study led by Swansea University argues that the health benefits of nature-based health care may depend not only on access to green space, but also on the biodiversity and ecological quality of the environments involved.

A bonanza for fans of the natural world: the digital library sharing 64m pages of scientif
The Biodiversity Heritage Library is an invaluable online archive of historic texts on species living and lost supplied by the world’s leading museums and universities. Now its future is in doubtSome go there to read about the wood that Victorian manufacturers used to make walkin
Restoring African landscapes with indigenous food-bearing trees
Deforestation is a major problem across Africa. It is widely recognized that deforestation harms biodiversity, but tree loss also harms dietary quality, as nutritious fruits, nuts, seeds and leaves disappear from the landscape. More than $1 billion has been pledged for landscape
Environmental DNA reveals impact of climate and humans on global river fish biodiversity
A global analysis of fish biodiversity using environmental DNA (eDNA) reveals how human activity and climate influence biodiversity patterns in river ecosystems. An international research team led by the University of Zurich, Eawag and Yunnan University has found that in warmer c
Wastewater management reverses widespread freshwater deoxygenation in China
Freshwater ecosystems worldwide have been suffering from declining oxygen levels—a trend known as deoxygenation—that threatens biodiversity, fisheries and ecosystem stability. However, a new study published in Nature Geoscience offers hope: targeted nutrient management via wastew
By saving ecosystems, environmental regulations help prevent biodiversity loss
Long-term conservation policies may help restore freshwater ecosystems and prevent extreme species loss, new research suggests.
Lake Chad supports 2.48 million waterbirds, emerging as one of Africa's top wetland refuge
A study titled "Monitoring major biodiversity stronghold in war zones: model predicts Lake Chad remains Africa's most important wetland for waterbirds" estimates that Lake Chad supports nearly 2.5 million waterbirds, making it one of the most important wetlands for birdlife in Af
How extreme weather impacts white stork survival in Bulgaria
A comprehensive 15-year study published in Biodiversity Data Journal details the growing threat of extreme weather to white storks (Ciconia ciconia) in Bulgaria. The research, which is part of the topical collection "Restoration of species of conservation importance," analyzes th
Sun-powered sponges may generate 11% of tropical coral reef productivity
Sun-powered sponges may generate 11% of tropical coral reef productivity
In marine environments, sponges tend to eat other organisms to get their nutrients. But a study published in Functional Ecology by researchers at the University of Amsterdam's Institute for Biodiversity and Ecosystem Dynamics (IBED), demonstrates how sponges may also use photosyn
Prescribed burns may generate over 20% of fine particle pollution in southeastern US
Prescribed fires are vital for reducing wildfire risk and sustaining forest biodiversity. But they also contribute significantly to air pollution and smoke exposure, according to new research from the University of Georgia. The issue is especially pertinent to the southeastern Un
