“Projected Global Loss of Mammal Habitat Due to Land-Use and Climate Change”



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.

“Too much biodiversity can be bad for some ecosystems”


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.

“Scientists: Border wall could threaten endangered species, environment”


The variety of habitat and ecosystems found along the U.S.-Mexico border make the region uniquely biodiverse.

“Sixth mass extinction of wildlife also threatens global food supplies”

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.

“Faulty fossil record analysis plagues studies of evolution, biodiversity”


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.

“Majority of potential UK fracking sites are rich in important wildlife”

Scientists say that almost two-thirds of the areas that have been labelled as suitable for shale gas extraction have levels of biodiversity equal to or above the national average, according to a new analysis of records collected from across the country.

“Agrichemicals and ever more intensive farming will not feed the world”

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.

“Agriculture and overuse greater threats to wildlife than climate change – study”

The African wild dog is one of more than 4,600 species under threat from land conversion for food, fodder or fuel crops.


Agriculture and the overexploitation of plants and animal species are significantly greater threats to biodiversity than climate change, new analysis shows.

“Biodiversity is below safe levels across more than half of world’s land – study”

Enormous swaths of dry forest in Paraguay’s sparsely populated Chaco Boreal region have been cleared for cattle ranching


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.
