Extreme weather such as hurricanes, torrential downpours and droughts will become more frequent in pace with global warming. Consequently, this increases the risk for species extinction, especially in bio diverse ecosystems such as coral reefs and tropical rainforests. Human impact means that flora and fauna become extinct at a rate 100-1000 times higher than normal. Climate change has been deemed as one of the main causes of species depletion. A research team in theoretical biology at...

Paris-based DIVERSITAS to spearhead global investigation into the '5 Ws' of biodiversity loss and how to mitigate it Concluding a four-year global consultation, international experts have agreed on key efforts needed to reduce the on-going loss of biodiversity and associated ecosystem services. On Day 2 of the Planet under Pressure conference in London (planetunderpressure2012.net) March 27, leaders of the global biodiversity research programme DIVERSITAS described the urgent need to...

Microorganisms play pivotal functions in nature, particularly within aquatic ecosystems. Whether in an ocean or a lake, they are key players in the food chain and the vitality of individual ecosystems. A team of researchers led by Arezoo M. Ardekani, the Rev. John Cardinal O'Hara, C.S.C., Assistant Professor of Aerospace and Mechanical Engineering at the University of Notre Dame, has shown that density stratification, a frequent feature of aquatic environments, has important ecological...

Image 1 - Past Disturbances Obscure Warming Impacts On Forests
2012-03-05 10:46:29

Past disturbances, such as logging, can obscure the effects of climate change on forest ecosystems. So reports a study just published in the Proceedings of the National Academy of Sciences. The paper, exploring nitrogen dynamics, found that untangling climate impacts from other factors can be difficult, even when scientists have access to decades of data on a forest's environmental conditions. Co-author Dr. Gene E. Likens of the Cary Institute comments, "Understanding how climate change is...

Image 1 - Unexpected Crustacean Diversity In Northern Freshwater Ecosystems
2012-03-04 06:16:02

A new species adds to evidence that subarctic regions with vanishing waters contain unique aquatic animals Freshwater ecosystems in northern regions are home to significantly more species of water fleas than traditionally thought, adding to evidence that regions with vanishing waters contain unique animal life. The new information on water fleas -- which are actually tiny crustaceans -- comes from a multi-year, international study that was published Feb. 24 in the journal Zootaxa....

Classic Model For Ecological Stability Revised
2012-02-20 04:32:08

Predator-prey relationships stabilize diverse ecosystems, according to calculation A famous mathematical formula which shook the world of ecology 40 years ago has been revisited and refined by two University of Chicago researchers in the current issue of Nature. In 1972, physicist Robert May rankled ecologists by publishing a simple model describing the relationship between diversity and stability in a theoretical ecosystem. Though ecologists had long believed that richer, more diverse...

Study suggests that plant biodiversity buffers negative climate change effects and drylands desertification An international team of researchers including Dr. Bertrand Boeken of the Jacob Blaustein Institutes for Desert Research at Ben-Gurion University of the Negev suggest in a new study that plant biodiversity preservation is crucial to buffer negative effects of climate change and desertification in drylands. The study titled, "Plant species richness and ecosystem multi-functionality...

Diverse Ecosystems Are Crucial Climate Change Buffer
2012-01-13 04:37:10

Preserving diverse plant life will help buffer the negative effects of climate change and desertification in drylands Preserving diverse plant life will be crucial to buffer the negative effects of climate change and desertification in the world's drylands, according to a new landmark study. The findings of the multi-author study, published January 12 in the journal Science, are based on samples of ecosystems in every continent except Antarctica. They confirm for the first time that...

High-priority sites for biodiversity conservation yield many of the world's ecosystem services, and ensuring that the stewards of such areas were paid by their beneficiaries could substantially alleviate poverty Land areas that are a priority for wildlife conservation provide relatively high levels of ecosystem services such as pollination, water purification, food production, and climate regulation, so safeguarding them is expected to benefit people. Assessing these benefits to...

The magnitude and depth of the Deepwater Horizon oil spill will require an unprecedented effort to determine the extent and severity of ecological damage and to develop restoration plans for affected areas in the Gulf of Mexico, says an interim report by the National Research Council.  A broad approach that focuses on repairing ecosystem processes -- such as fisheries production -- in addition to replacing natural resources damaged by the spill could offer more options for restoring the...

Rainforests
2013-04-19 19:33:20

Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...

Taiga
2013-04-19 18:21:46

Taiga, or otherwise known as boreal forest, is a biome that is characterized by coniferous forests made up mostly of spruces, larches, and pines. The taiga is the world’s largest terrestrial biome. In North America, it covers most of inland Canada and Alaska as well as portions of the extreme northern continental United States and is known as the Northwoods. It covers most of Sweden, Finland, much of Norway, lowland/coastal areas of Iceland, much of Russia, northern Kazakhstan, northern...

Environmental Science
2014-01-12 00:00:00

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...
