Graph of the Day: Major threats to bees in Europe

19 March 2015 (IUCN) – With the majority (56.7%) of European bee species being listed as Data Deficient, any overview of the threats to the continental apifauna will necessarily be incomplete. However, for conservation and management of bee diversity to be undertaken effectively, it is critical to have a clear understanding of taxonomy and ecology […]

Acidic oceans implicated in Earth's worst mass extinction – ‘These findings may help us understand the threat posed to marine life by modern-day ocean acidification’

By Will Dunham; Editing by Mohammad Zargham9 April 2015 WASHINGTON (Reuters) – It is one of science’s enduring mysteries: what caused the worst mass extinction in Earth’s history. And, no, it is not the one that wiped out the dinosaurs. Scientists said on Thursday that huge amounts of carbon dioxide spewed from colossal volcanic eruptions […]

As Arctic sea ice dwindles, polar bears won’t survive on land – ‘Why would anyone think this nutritionally poor environment suddenly could support whole populations of the world’s largest bears?’

1 April 2015 (Polar Bears International) – Scientists have known for years that polar bears forced ashore in summer by melting sea ice may feed on foods like bird eggs, berries, and small mammals. But would polar bears be able to survive in a warming Arctic by eating land-based foods? The short answer: no. A […]

Massive amounts of fresh water, glacial melt pouring into Gulf of Alaska – Melt adds 57 cubic kilometers of water per year

CORVALLIS, Oregon, 19 March 2015 (OSU) – Incessant mountain rain, snow and melting glaciers in a comparatively small region of land that hugs the southern Alaska coast and empties fresh water into the Gulf of Alaska would create the sixth largest coastal river in the world if it emerged as a single stream, a recent […]

Nitrogen emissions in smog threatens to ‘massacre’ world’s forests – ‘If the situation remains as it is, most forests in southern China will be destroyed within decades’

By Stephen Chen29 March 2015 (SCMP) – Thick smog could kill off most southern China’s natural forests within decades and threatens trees around the world unless nations take action, say scientists. A 13-year study by Chinese scientists has revealed strong evidence to show the danger is being caused by nitrogen emissions in the atmosphere. “It […]

Graph of the Day: Drivers of declines in status for pollinator birds and mammals

10 February 2015 (Conservation Letters) – Drivers of declines in status for pollinator birds (1988-2012) and mammals (1996-2008). ABSTRACT: Biodiversity is declining, with direct and indirect effects on ecosystem functions and services that are poorly quantified. Here we develop the first global assessment of trends in pollinators, focusing on pollinating birds and mammals. A Red […]

Graph of the Day: Californian anchovy (Engraulis mordax) depletion, 1950-2012

25 March 2015 (Desdemona Despair) – The Pew Charitable Trusts support excellent ongoing research on the state of the oceans, and recently Pew’s Paul Shively wrote a good story on the current mass-starvation event among California sea lions (“Starving pups: It’s more than a sea lion problem”). Mr. Shively observes that in addition to sardines, […]

Sea lion strandings on San Diego beaches reach record numbers – ‘They’ve been very malnourished and in some cases, bags of bones’

By Dave Schwab26 March 2015 (SD News) – A surprising influx of malnourished and dehydrated sea lions has SeaWorld San Diego and its trainers working overtime to nurse them back to health before returning them to the wild. More than 550 marine mammals have been rescued so far in 2015, which is more than double […]

Graph of the Day: Deforestation inside and outside riparian protected areas in the Brazilian Amazon, 1988-2010

ABSTRACT: Brazilian environmental law imposes more restrictions on land-use change by private landowners in riparian forests than in non-riparian forest areas, reflecting recognition of their importance for the conservation of biodiversity and key ecosystem services. A 22-year time series of classified Landsat images was used to evaluate deforestation and forest regeneration in riparian permanent preservation […]

Starving pups: It’s more than a sea lion problem

By Paul Shively23 March 2015 (Pew Charitable Trusts) – Here on the West Coast, sea lions evoke plenty of emotions. Some people love them, while others see them as a nuisance. Whatever your view, it’s unsettling to see hundreds of emaciated sea lion pups turning up along the California coast in what could be one […]
