“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”

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.

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.

Renowned biologist E.O. Wilson wants to set aside half of the planet as protected areas for nature. But is this possible? And, if so, how would it work?

A new study suggests our knowledge of Earth’s biodiversity is extremely limited. According to the numbers recently crunched by scientists at Indiana University, 99.999 percent of the planet’s species remain undiscovered.

“UN biodiversity report highlights failure to meet conservation targets”

International efforts to meet targets to stem the loss of wildlife and habitats are failing miserably, according to a UN report.

The Global Biodiversity Outlook 4, published as nearly 200 countries meet on Monday in South Korea in a bid to tackle biodiversity loss, paints a damning picture of governments’ efforts to meet a set of targets agreed in 2010 to slow the destruction of species’ habitats, cut pollution and stop overfishing by the end of the decade.
