“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.

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.

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.

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”

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

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.

In the 300 years since the Swedish naturalist Carolus Linnaeuspioneered scientific classification, we might have managed to recognise only 2% of Earth’s biodiversity.
