Wetlands may be the least understood ecosystem, but their value is immense, according to Distinguished Professor W. Carter Johnson of the South Dakota State University Department of Natural Resource Management. “Anything that affects them will have a big impact on the landscape.”
A new study calls into question the evolutionary stability of an ecological explanation of biodiversity.
Non-native invasive plants have overrun some parts of the Galapagos Islands, finds a new study by The University of Western Australia. Mandy Trueman, a PhD researcher at UWA School of Plant Biology, has led the study and has delivered a map and a related database that provides information about native species as well as introduced species.
Researchers from different universities studied the potential health and economic benefits of plans proposed on the control of air pollution in over-polluted regions of China. According to them, the costs related to the fatality and disability caused by air pollution came down by 50% in Taiyuan, China’s Shanxi Province capital between 2001 and 2010. The result of the study is published online in the Environment International journal.
A Commission led by Ohio State University Professor, William Martin and Liverpool School of Tropical Medicine Professor, Stephen Gordon, studied the health effects of indoor air pollution. The study, published in the journal - The Lancet Respiratory Medicine, estimated that solid fuels like coal, charcoal or wood are being used for heating, cooking and lighting purposes by one-third of the human population, globally.
Tufts University’s Charles C. Chester, Wildlife Conservation Society’s Jodi A. Hilty and World Commission on Protected Areas/IUCN’s Lawrence S. Hamilton have together published a new paper on conservation, climate change and connectivity in mountain regions. This study has been published in the Journal of Mountain Ecology.
Irina Ovcarenko, a scientist at Finland's MTT Agrifood Research, has as part of her thesis, conducted research on the ecology and genetic diversity of the greenhouse whitefly. Her study provides new insight about their survival in Finland and would also help in planning pest management.
Scientists at MIT, in collaboration with the Weizmann Institute of Science in Israel have discovered that corals are not as passive as previously thought. The team have found that corals manipulate their environment to force water into turbulent patterns which enables them to exchange nutrients and dissolved gases with their surroundings.
Scientists at the University of Southampton have found that the rising sea level and climate change continue to impact the coastal regions and hence appropriate measures need to be taken to better manage the effect of these climatic changes.
Nitrite-oxidising bacteria play a major role in the Earth’s natural nitrogen cycle and man-made wastewater treatment plants. For many years, it was believed that these nitrite-oxidising bacteria use only nitrite as their main source of energy. Now, researchers at the University of Vienna have demonstrated that these specialist bacteria may also use an alternative source of energy, such as hydrogen.
