Science Daily A new study looks at the growth of global livestock farming and the threat to biodiversity, and the health risks to both humans and domesticated animals. The growth of global livestock farming is a threat to our biodiversity and also increases the health risks to both humans and domesticated animals. The patterns that link them are at the heart of a study published in Biological Conservation by a scientist from the Institute of Evolution Sciences of Montpellier (ISEM -- CNRS/Université de Montpellier/IRD/EPHE) and the French Agricultural Research Centre for International Development's (CIRAD) ASTRE laboratory.

To the untrained eye, the two species might pass as overgrown house cats. They're actually "felids" or mammals belonging to felidae , a family of wild cats.  Both live side by side in the wilds of Ontario, north of Lake Huron (see map). Researchers at the University of Trent (U of T) in Peterborough, Ontario, looked at bobcat and lynx numbers, movements and behaviour over three winters.  Their findings seem to show the bobcat holding an edge over the lynx in the struggle to survive, if not thrive in their rapidly-changing world.  The scientists are unable to give hard numbers. But, "harvest records" which document the numbers taken by trappers, offer an insight.  The lead author, Robby Marrotte, tells PinP, "We've noticed that the number of lynx harvested on traplines has decreased

New research by a team of Canadian biologists,  seems to support critics who've long argued that wolves are being sacrificed unnecessarily in efforts to save iconic mountain caribou in British Columbia and Alberta from possible extinction. Since the 80s, authorities in the two provinces have been conducting "culls" which have probably killed thousands of wolves since. Culls involve either shooting the animals from helicopters, poisoning them or, in at least one case - an eight-year campaign of sterilization. The iconic caribou. A Wikimedia photo. Yet caribou populations all over Canada, continue to plummet. Thanks to  declines in all sub-species, they're now classified, nationwide as either threatened or endangered. Some of the steepest reductions have occurred in mountainous regions in the two westernmost provinces. A few years ago, they were declared extinct south of the bor

Less than 32% of Antarctica is made up of areas that are free from human interference, and these areas are declining as human activity increases, reports a paper published in Nature. The study finds that although 99.6% of the continent can be considered to be wilderness (a relatively undisturbed environment), this area does not include much of its biodiversity. Despite Antarctica’s isolation, the continent is under increasing pressure from human activity, including scientific research, the development of infrastructure and tourism. However, the total area of wilderness on the continent is unknown, as is the extent to which Antarctica’s biodiversity is contained within this.
