Expert assessment: Ocean acidification may increase 170 percent this century

Expert assessment: Ocean acidification may increase 170 percent this century

In a major new international report, experts conclude that the acidity of the world’s ocean may increase by around 170% by the end of the century bringing significant economic losses. People who rely on the ocean’s ecosystem services — often in developing countries — are especially vulnerable. A group of experts have agreed on ‘levels […]

New approach to identify possible ecological effects of releasing genetically engineered insects

New approach to identify possible ecological effects of releasing genetically engineered insects

University of Minnesota researchers have developed a new approach for identifying potential environmental effects of deliberate releases of genetically engineered (GE) insects. The researchers outline their approach in a paper in the journal Ecology and Evolution. The authors include professor of entomology David Andow and Aaron David, Joe Kaser, Amy Morey and Alex Roth — […]

Changes to fisheries legislation have removed habitat protection for most fish species in Canada

Changes to fisheries legislation have removed habitat protection for most fish species in Canada

Federal government changes to Canada’s fisheries legislation have eviscerated the ability to protect habitat for most of the country’s fish species, scientists at the universities of Calgary and Dalhousie say in a new study. The changes were politically motivated, unsupported by scientific advice — contrary to government policy — and are inconsistent with ecosystem-based management, […]

Global warming in the Canadian arctic

Global warming in the Canadian arctic

Ph.D. student Karita Negandhi and professor Isabelle Laurion from INRS’Eau Terre Environnement Research Centre, in collaboration with other Canadian, U.S., and French researchers, have been studying methane emissions produced by thawing permafrost in the Canadian Arctic. These emissions are greatly underestimated in current climate models. Their findings, published in the journal PLOS ONE, illustrate the […]

„E posibila o masiva poluare cu levigat in vecinatatea Timisoarei in urma prospectiunilor petroliere”

„E posibila o masiva poluare cu levigat in vecinatatea Timisoarei in urma prospectiunilor petroliere”

In Timis incep prospectiunile dupa petrol. SC Prospectiuni SA incepe sa caute pe cuprinsul judetului locuri unde s-ar putea gasi astfel de resurse. Nimeni nu s-a gandit insa ce se va intampla in zona Sag-Parta, acolo unde inca mai „mocneste” fosta groapa de gunoi a Timisoarei. Pana acum… pentru ca la aceasta problema s-a gandit […]

Власти Тегерана закрыли школы и детсады в связи с высоким загрязнением воздуха

Власти Тегерана закрыли школы и детсады в связи с высоким загрязнением воздуха

Как высказала Государственная радиовещательная компания Ирана, возвышенный уровень загрязнения воздуха заставил власти страны выпустить приказ о временном закрытии начальных школ и детских садов в провинции Тегеран в течение трех дней, начиная с минувшего воскресенья. В связи с загрязнением воздуха Кризисным комитетом по охране окружающей среды было еще рекомендовано сократить рабочий день в государственных учреждениях в […]

First detailed map of global forest change

First detailed map of global forest change

A University of Maryland-led, multi-organizational team has created the first high-resolution global map of forest extent, loss and gain. This resource greatly improves the ability to understand human and naturally-induced forest changes and the local to global implications of these changes on environmental, economic and other natural and societal systems, members of the team say. […]

Amazon rainforest more able to withstand drought than previously thought

Amazon rainforest more able to withstand drought than previously thought

New research suggests that the Amazon rainforest may be more able to cope with dry conditions than previously predicted. Researchers at the University of Exeter and Colorado State University used a computer model to demonstrate that, providing forest conservation measures are in place, the Amazon rainforest may be more able to withstand periods of drought […]

Evidence of 3.5-billion-year-old bacterial ecosystems found in Australia

Evidence of 3.5-billion-year-old bacterial ecosystems found in Australia

Reconstructing the rise of life during the period of Earth’s history when it first evolved is challenging. Earth’s oldest sedimentary rocks are not only rare, but also almost always altered by hydrothermal and tectonic activity. A new study from a team including Carnegie’s Nora Noffke, a visiting investigator, and Robert Hazen revealed the well-preserved remnants […]

Infected butterflies lead geneticists up the garden path

Infected butterflies lead geneticists up the garden path

For animal species that cannot be distinguished using their external characteristics, genetic techniques such as DNA barcoding can help to identify cryptic species. An international team of researchers led by the Helmholtz Center for Environmental Research (UFZ) has brought out an article in the open-access journal PLOS ONE demonstrating how a bacterial infection can mimic […]
