Global wildlife populations down by half since 1970: WWF

Read the full story from Planet Ark.

The world populations of fish, birds, mammals, amphibians and reptiles fell overall by 52 percent between 1970 and 2010, far faster than previously thought, the World Wildlife Fund said on Tuesday.

The conservation group’s Living Planet Report, published every two years, said humankind’s demands were now 50 percent more than nature can bear, with trees being felled, groundwater pumped and carbon dioxide emitted faster than Earth can recover.

Audubon to protest bird ‘death trap’ stadium design

Read the full story from Minnesota Public Radio.

The Minneapolis chapter of the Audubon Society is organizing a protest at the new Vikings stadium this weekend calling on the Minnesota Sports Facilities Authority and the Minnesota Vikings to change the design of the new billion dollar stadium.

The stadium’s open interior and lights may attract birds, who can be killed or injured when they fly into the transparent glass.

More Than Half Of North American Birds In Trouble Thanks To Climate Change

As the world gets warmer, the Baltimore oriole will no longer be found in Maryland. The Mississippi kite will move north, east and pretty much out of its namesake state. And the California gull will mostly be a summer stranger to the Golden State.

Those are among the conclusions in a new National Audubon Society report that looks at the potential effects of global warming on birds by the year 2080.

Avian Knowledge Network (AKN)

The Avian Knowledge Network (AKN) is a partnership of people, institutions and government agencies supporting the conservation of birds and their habitats based on data, the adaptive management paradigm, and the best available science. AKN partners act to improve awareness, purpose, access to, and use of data and tools at scales ranging from individual locations to administrative regions (e.g., management areas, states, countries) and species ranges. The Illinois Natural History Survey is a network partner.

AKN’s resources include data sets and data manipulation tools. You can also add your data.

What We Know About Entanglement and Ingestion: New NOAA reports sum up the state of science on entanglement and ingestion

The NOAA Marine Debris Program, in partnership with the National Centers for Coastal Ocean Science, has published reports that assess the current state of science on two marine debris impacts: ingestion and entanglement.

The reports examine existing scientific literature to determine what we know about these impacts, as well as gaps in knowledge and how they may be addressed.

Reports

Entanglement of Marine Species in Marine Debris with an Emphasis on Species in the United States
From reports in the United States, at least 115 marine species are impacted by entanglement, including mammals, turtles, birds, fish, and crabs. Most marine debris entanglement reports involved pinnipeds, particularly northern fur seals and Hawaiian monk seals, as well as sea turtles. Worldwide, at least 200 species are impacted.

Occurrence of Health Effects of Anthropogenic Debris Ingested by Marine Organisms
An estimated 26 marine mammal species, including toothed whales, manatees, and multiple seal species, as well as all sea turtle species have been confirmed to ingest marine debris. Over one-third of sea bird species ingest plastic. Research to-date has characterized the types, sources and impacts of ingestible debris, yet the overall effects on animals remain poorly understood.
