The Wildlife Conservation Society launched a global effort today to take direct responsibility for the continued survival of some of the world’s most endangered tortoises and freshwater turtles.
There have been many scientific studies looking at the levels of toxic mercury (Hg) in fish. After all, fish can end up directly on our plate. However, far fewer studies have examined Hg levels in aquatic insects. This is a significant oversight because aquatic insects are an important source of Hg to fish and even terrestrial wildlife.
While many enjoyed a mild winter and an early spring with record-breaking temperatures, the warm weather also prompted many bugs to show up earlier than usual. The question is, will bug populations be larger this summer?
Research to green alternative energy technologies has led to a dye-sensitized solar cell that uses a bacteria and dye to generate energy. It is also friendlier to the environment and living organisms.
Global warming may initially make the grass greener, but not for long, according to new research conducted at Northern Arizona University. The study, published this week in Nature Climate Change, shows that plants may thrive in the early stages of a warming environment but begin to deteriorate quickly
In a new study reported in Nature, climate scientist Rob DeConto and colleagues propose a new mechanism, changes in the Earth’s tilt and orbit, to explain the source of carbon that fed extreme warming events about 55 million years ago and a sequence of similar, smaller warming events afterward.

Fishing for herring, anchovy, and other “forage fish” in general should be cut in half globally to account for their critical role as food for larger species, recommends an expert group of marine scientists in a report released today.
Recent research indicates advancing sustainability in the area of curriculum is falling behind other efforts to incorporate sustainability in the higher ed setting, such as in facilities planning. This two-part series will look at a few of WIU's curriculum-oriented and academic programs designed to help incorporate sustainability in formal instruction. Part 1 is available at http://www.newswise.com/articles/view/586292/
Evidence from fossilized raindrop impressions from 2.7 billion years ago indicates that an abundance of greenhouse gases most likely caused the warm temperatures on ancient Earth.
Delicate wetland ecosystems that offer important wildlife habitats are threatened from multiple sources. One is the rapid expansion of nonnative, invasive plants that choke out natural species and alter the wetlands. Perennial pepperweed poses such a threat to seasonal wetlands in California and other western states.
Specialists agree that environmental intelligence must be a national priority, as it is essential to protecting our citizens, economy, and national security. Lack of information – particularly from Earth-orbiting sensors and systems -- could have devastating consequences, chiefly in the area of risk management.
Wildlife does not respect property boundaries. Therefore, protecting endangered species cannot be accomplished on government-owned lands alone. The cooperation and assistance of private landowners is essential. However, some landowners see government biodiversity programs, such as the Endangered Species Act, as a threat to independent management of their property.
The Wildlife Conservation Society and partners signed an agreement this month that will safeguard some 80,000 acres of intact forest in Guatemala in the heart of the sprawling Maya Biosphere Reserve.

The water flowing through Venice’s famous canals laps at buildings a little higher every year – and not only because of a rising sea level. Although previous studies had found that Venice has stabilized, new measurements indicate that the historic city continues to slowly sink, and even to tilt slightly to the east.

Some 32 social scientists and researchers from around the world, including a Senior Sustainability Scholar at Arizona State University, have concluded that fundamental reforms of global environmental governance are needed to avoid dangerous changes in the Earth system. The scientists argued in the March 16 edition of the journal Science that the time is now for a “constitutional moment” in world politics.

Wild orangutans that have come into contact with eco-tourists over a period of years show an immediate stress response but no signs of chronic stress, unlike other species in which permanent alterations in stress responses have been documented, new research from an Indiana University anthropologist has found.
People in the US may be at higher risk for Chagas disease than previously understood. A new study finds that 38% of kissing bugs collected in Arizona and California contained human blood and that more than 50% of the bugs also carried the parasite that causes this life-threatening disease. This upends the view that US kissing bug species don’t regularly feed on people and suggests that Chagas could spread, driven north by climate change.
New research has found that one type of pavement sealcoat, common on driveways and parking lots throughout the nation, has significant health and ecosystem implications.

A team of researchers has just published a new paper, lead authored by Boston University Professor of Earth Sciences Richard W. Murray, that provides compelling evidence from marine sediment that supports the theory that iron in the Earth’s oceans has a direct impact on biological productivity, potentially affecting the amount of carbon dioxide in the atmosphere and, in turn, atmospheric temperature. These findings have been published in the March 11, 2012 online edition of the journal Nature Geoscience.
