Human pressure on the environment is driving a global decline of biodiversity. Anticipating whether this trend can be reverted under future scenarios is key to supporting policy decisions. We used the InSiGHTS framework to model the impacts of land-use and climate change on future habitat availability for 2,827 terrestrial mammals at 15 arcmin resolution under five contrasting global scenarios based on combinations of representative concentration pathways and shared socio-economic pathways between 2015 and 2050. Mammal habitat declined globally by 5%–16% depending on the scenario. Africa (with declines up to 25%) and South America were the most affected regions. African insectivores, primates, Australian carnivorous marsupials and marsupial moles, and South American opossums declined the most. Tackling this loss would require a mix of actions across scales, including a global shift toward sustainability, addressing land-use change in sub-Saharan Africa, and helping endemic species track climate change in South America.
Conservation efforts on coasts around the UK have helped rare marine life including seahorses and basking sharks make an unexpected comeback.
New research suggests it’s possible to have too much biodiversity. In lab tests, scientists in Switzerland showed elevated levels of biodiversity can destabilize ecosystems under certain conditions.
The variety of habitat and ecosystems found along the U.S.-Mexico border make the region uniquely biodiverse.
The sixth mass extinction of global wildlife already under way is seriously threatening the world’s food supplies, according to experts.
There are tens of thousands of wild or rarely cultivated species that could provide a richly varied range of nutritious foods, resistant to disease and tolerant of the changing environment. But the destruction of wild areas, pollution and overhunting has started a mass extinction of species on Earth. The focus to date has been on wild animals – half of which have been lost in the last 40 years – but the new report reveals that the same pressures are endangering humanity’s food supply, with at least 1,000 cultivated species already endangered.
Researchers in England believe at least 150 studies on evolution and biodiversity penned since 2007 stand on shaky scientific ground — built on poor analysis and flawed assumptions.
The authors of a new study, published in the journal Methods in Ecology and Evolution, argue recent attempts to “correct” the fossil record have further perverted it.
Just when climate change demands a more diverse and adaptable food system, resilient to changing conditions, agriculture is being dragged further down an ever-narrowing agroindustrial route.
Habitat destruction has reduced the variety of plants and animals to the point that ecological systems could become unable to function properly, with risks for agriculture and human health, say scientists.
