Albatrosses in decline from fishing and environmental change
November 21, 2017 01:49 PM - British Antarctic Survey

The populations of wandering, black-browed and grey-headed albatrosses have halved over the last 35 years on sub-antarctic Bird Island according to a new study published today (20 November) in the journal Proceedings of the National Academy of Sciences.

In bee decline, fungicides emerge as improbable villain

When a Cornell-led team of scientists analyzed two dozen environmental factors to understand bumblebee population declines and range contractions, they expected to find stressors like changes in land use, geography or insecticides.

Three studies from UTA's clear lab detect harmful pathogenic bacteria in Texas groundwater near natural gas extraction sites

Three new research studies from the University of Texas at Arlington have found harmful pathogenic bacteria in Texas groundwater near unconventional natural gas extraction sites.

NASA Links Port-City Sea Levels to Regional Ice Melt
November 21, 2017 11:13 AM - NASA Jet Propulsion Laboratory (JPL)

new NASA tool links changes in sea level in 293 global port cities to specific regions of melting land ice, such as southern Greenland and the Antarctic Peninsula. It is intended to help coastal planners prepare for rising seas in the decades to come.

Researcher seeks to protect where the wild things walk
November 21, 2017 08:06 AM - University of British Columbia

UBC research is paving the way for a route that will serve as a pilot project to protect green space and allow wildlife to move throughout the Okanagan Valley.

Kelowna was identified in the 2016 Stats Canada census as one of the fastest-growing cities in Canada. With growth comes development and UBC Professor Lael Parrott says the region is in danger of fragmenting low-elevation ecosystems and losing the habitat and movement routes needed by wildlife, especially on the east side of Okanagan Lake.

Nebraska Approves Keystone XL, But Requires Different Route Through State
November 20, 2017 05:44 PM - Yale Environment 360

Nebraska regulators have given the final approval for the Keystone XL pipeline to run through their state, eliminating the last major regulatory obstacle preventing the completion of the 1,179-mile pipeline system that would help carry tar sands oil from Alberta, Canada to refineries in Texas.

Study Pinpoints Arctic Shorebird Decline
November 20, 2017 05:40 PM - Wildlife Conservation Society

A new study co-authored by WCS (Wildlife Conservation Society) addresses concerns over the many Arctic shorebird populations in precipitous decline. Evident from the study is that monitoring and protection of habitat where the birds breed, winter, and stopover is critical to their survival and to that of a global migration spectacle.

Researchers pin down one source of a potent greenhouse gas
November 20, 2017 01:47 PM - Ohio State University

A study of a Lake Erie wetland suggests that scientists have vastly underestimated the number of places methane-producing microbes can survive—and, as a result, today’s global climate models may be misjudging the amount of methane being released into the atmosphere.

Thinking Big by Burning Small

A recent paper by scientists from Wits University in South Africa shows how creative fire management can increase habitat for wildebeest and other grazing animals in national parks.

As Oceans Warm, the World's Kelp Forests Begin to Disappear
November 20, 2017 12:26 PM - Yale Environment 360

A steady increase in ocean temperatures — nearly 3 degrees Fahrenheit in recent decades — was all it took to doom the once-luxuriant giant kelp forests of eastern Australia and Tasmania: Thick canopies that once covered much of the region’s coastal sea surface have wilted in intolerably warm and nutrient-poor water. Then, a warm-water sea urchin species moved in. Voracious grazers, the invaders have mowed down much of the remaining vegetation and, over vast areas, have formed what scientists call urchin barrens, bleak marine environments largely devoid of life.
