Human footprint driving mammal extinction crisis – News

Human impacts are the biggest risk factor in the possible extinction of a quarter of all land-based mammals, according to a University of Queensland study.

Researchers compared a 16-year trend in the global human footprint with the extinction risk of around 4500 country-based mammal species.

UQ School of Earth and Environmental Sciences Adjunct Fellow Dr Moreno Di Marco said the analysis redefined how we looked at mammal extinctions.

"We live in an era when one in every

"To get a clearer idea of Det er systematisk, der fører til disse nedfald, vi besluttede at kombinere mapping af menneskelige pres med udløbsrisikovurderingsdata for dyrearter. "

De forskere fandt at human footprint var stærkt forbundet med udryddelsesrisiko cha nge for country-based mammals ̵

1; more than any other variable they tested.

"Human impacts in areas originally in a natural or semi-natural state – those with a footprint of only three or below on a zero-to -50 scale – was the main driver of extinction risk change in mammal species, "Dr. Di Marco said.

" In terms of conservation efforts, it makes us look twice at what high impact human activities really are, since even seemingly low-level impacts are decimating species. "

UQ's Professor James Watson said the findings were invaluable for future conservation efforts.

" What we have created has huge potential to provide rapid assessment of species extinction risk, without having to go through extensive expert consultation every time, "he said.

" It has the potential to change how we assess biodiversity conservation status globally. "

" The international community has a mission to prevent the decline of species, and

"The need to see the big picture before it's too late."

The study has been published in Nature Communications (DOI: 10.1038 / s41467-018-07049-5).
