Biocontrol agents, such as insects, are often released outside of their native ranges to control invasive plants. But scientists in Montana have found that through complex community interactions among deer mice, native plants and seeds, the presence of an introduced fly may exacerbate the effects of the invasive plant it was meant to control
What are the consequences of human-made tinkering with land cover and hydrology on surrounding native desert ecosystems and biodiversity? This question forms the backdrop for a case study proffered by an ASU research team and published in the journal BioScience, which found that one of the most profound impacts of urbanization is the “reconfiguration of surface hydrology.”
American Aquascapes has provided the Triangle and the Triad with custom-designed water features for 11 years. Now, the company is proud to announce its implementation of new RainBank Systems for water landscaping without...
The Ecological Society of America today criticized the Bush administration's Aug. 15 proposal to reinterpret the Endangered Species Act, which would impose regulatory changes eliminating the requirement for federal projects to undergo independent scientific review
Power-generating wind turbines have long been recognized as a potentially life-threatening hazard for birds. But at most wind facilities, bats actually die in much greater numbers
International security experts believe climate change related damage to global ecosystems and the resulting competition for natural resources may increasingly serve as triggers for wars and other conflicts in the future
New research, reported this week in the online early edition of the Proceedings of the National Academy of Sciences, finds that coal burning, primarily in North America and Europe, contaminated the Arctic and potentially affected human health and ecosystems in and around Earth's polar regions.
The impact of global warming in the Arctic may differ from the predictions of computer models of the region, according to a pair of Penn State biologists. The team -- which includes Eric Post, a Penn State associate professor of biology, and Christian Pederson, a Penn State graduate student -- has shown that grazing animals will play a key role in reducing the anticipated expansion of shrub growth in the region, thus limiting their predicted and beneficial carbon-absorbing effect.
Algae are tiny biological factories that use photosynthesis to transform carbon dioxide and sunlight into energy so efficiently that they can double their weight several times a day, producing oil in the process - 30 tim...
Human activities are cumulatively driving the health of the world's oceans down a rapid spiral, and only prompt and wholesale changes will slow or perhaps ultimately reverse the catastrophic problems they are facing.
