Banking on biodiversity

The diversity of life on Earth gives ecosystems the resilience they need to thrive. Yet every day scores of plants and animals go extinct, victims of activities we humans undertake to feed, clothe, house and trans­port ourselves. How can we meet our own needs without destroying that which sustains us? The west coast of Vancouver Island in British Columbia, Canada, has a rugged, involuted shoreline, etched by fjords, sand dunes and shel­tered coves. It is sandwiched between two biospheres, the dark swelling sea and the emerald temperate rain forest, and it attracts all sorts—from salmon to surfers. As idyllic as … Read more…

US polar bears mark their territory

More than two years after Alaskan polar bears were given a protection status of “threatened species” by the US Endangered Species Act, the Obama administration set aside on Wednesday 24 November 484,330 sq kilometres — twice the size of the UK — in Alaska as “critical habitat”. Almost all of the area is offshore sea ice habitat — where polar bears spend most of their time hunting seals, breeding and travelling—in the Beaufort and Chukchi seas off Alaska’s northern coast. It also includes on-shore barrier islands and land used for making dens. About 4,800 polar bears ramble along Alaska’s ice and … Read more…

Taxonomy in Trouble in Canada

Canada is at risk of losing its taxonomic expertise, according to a report released today. The report details stagnant research funding, greying experts, a lag in digitization and a lack of support for national collections. This is threatening Canada’s understanding of its biodiversity, and the ecosystem services it provides, the report concludes. “Canadian contributions to describing new species has dropped from being 6th in the world to 14th in the last decade,” says Thomas Lovejoy, Biodiversity Chair at the Heinz Center for Science, Economics and the Environment, who chaired the panel of 14 Canadian and international experts who authored the report. “The … Read more…

Cold cash for cold science

The recent funding wrap-up from the international polar year (IPY) has left many Canadian researchers scratching their heads, trying to find a way to continue their arctic science projects. A new grant from the Natural Sciences and Engineering Research Council of Canada may help close that research-funding gap. In its announcement yesterday, NSERC opened a competition to fund large-scale research with a focus—for this round of funding—on northern earth systems. The Discovery Frontiers initiative will heft Can$4 million over five years on the successful research team to study the physical, chemical, biological and social factors that affect the North and its … Read more…

Free Radicals Radio: Bring on the bugs!

Babes in the woods Get outside Can a walk in the woods really change us? Scientists are beginning to think so. There’s evidence to suggest that being in a busy city environment can reduce the brain’s capacity to remember things and lower self-control. Kids are driven to school and back, and off to soccer practice, and then when they get home, they turn on the computer or TV and settle down to an evening of screen-tertainment. The growing children and nature movement suggests children’s problems with obesity, attention span and lack of understanding of the environment are connected to less … Read more…
