Microplastic pollution reduces energy production in a microscopic creature found in freshwater worldwide, new research shows. Paramecium bursaria contain algae that live inside their cells and provide energy by photosynthesis. The results of a NEW STUDY showed a 50% decline in net photosynthesis—a major impact on the algae's ability to produce energy and release oxygen

We are a species that is superb at killing, says veteran oceanographer, who calls for us to stop treating fish like crops and give them the respect they deserve

The IPBES #PandemicsReport is one of the most scientifically robust examinations of the evidence and knowledge about links between pandemic risk and nature since the COVID-19 pandemic began - with 22 of the world's leading experts from fields as diverse as epidemiology, zoology, public health, disease ecology, comparative pathology, veterinary medicine, pharmacology, wildlife health, mathematical modelling, economics, law, and public policy as authors of the report. The expertise of the 22 authors was further augmented by contributions and knowledge resources from the Convention on Biological Diversity, the Intergovernmental Panel on Climate Change, the Convention on International Trade in Endangered Species, the United Nations Convention to Combat Desertification, and the World Health Organization - as well as a peer review process.

The world may be facing a devastating “hidden” collapse in insect species due to the twin threats of climate change and habitat loss.

Only rarely does a book truly change the world. In the nineteenth century, such a book was Charles Darwin’s On the Origin of Species. For the twentieth century, it was The Limits to Growth. Not only did this best-selling 1972 publication help spur the environmental movement, but it showed that the underlying dynamics of the modern industrial world are unsustainable on the timescale of a couple of human lifetimes. This was profoundly important information, and it was delivered credibly and clearly, so that every policy maker could understand it.

Tree diversity is fundamental for forest ecosystem stability and services. However, because of limited available data, estimates of tree diversity at large geographic domains still rely heavily on published lists of species descriptions that are geographically uneven in coverage. These limitations have precluded efforts to generate a global perspective. Here, based on a ground-sourced global database, we estimate the number of tree species at biome, continental, and global scales. We estimated a global tree richness (≈73,300) that is ≈14% higher than numbers known today, with most undiscovered species being rare, continentally endemic, and tropical or subtropical. These results highlight the vulnerability of global tree species diversity to anthropogenic changes.

New research sees two-thirds of mollusc types only found living by hydrothermal vents added to IUCN’s red list of endangered species

It may take bees multiple generations to recover from being exposed to insecticides even just once, research shows. A new research, published in PNAS, shows that even a single exposure to insecticides in a bee’s first year of life affects offspring production, and since the effects of the pesticides are cumulative, this results in an overall decrease in population

There is a myth about human beings that withstands all evidence. It’s that we always put our survival first. This is true of other species. When confronted by an impending threat, such as winter, they invest great resources into avoiding or withstanding it: migrating or hibernating, for example. Humans are a different matter.

The ivory-billed woodpecker, along with 22 other species of birds, fish, mussels and other wildlife, is set to be declared extinct and removed from the endangered species list, US federal wildlife officials announced Wednesday.

A new conservation tool could help put thousands of threatened animal and plant species on the road to recovery, allowing creatures such as the Sumatran rhino and the California condor to flourish once again.

The spread of electrical lighting is blocking out the stars and threatens the health of many species … including humans. Now our national parks plan to take back the night

Humans will cause so many mammal species to go extinct in the next 50 years that the planet's evolutionary diversity won't recover for 3 to 5 million years, a team of researchers has found.
