Colorado Aspens Destroyed By Hotter Temperatures
2013-02-12 09:23:19

Alan McStravick for redOrbit.com - Your Universe Online Two brothers at the Carnegie Institution for Science have undertaken the study of the widespread die-off of Colorado aspen trees. Their most recent study, published online in the journal Global Change Biology, follows on the heels of a previous study they did. Their last study explored two competing theories for how forest trees tend to die off in drought conditions. The first theory suggested that trees actually starved to death...

Antarctica's Salty Don Juan Pond Offers Watery Hope For Mars
2013-02-07 15:42:19

Lawrence LeBlond for redOrbit.com - Your Universe Online Several bodies of water around the world are known for their salty content. Among the most well-known are the Great Salt Lake in Utah and the Dead Sea. But these bodies of water pale in comparison to Don Juan Pond in Antarctica, known as the saltiest body of water on Earth. The pond, situated in the McMurdo Dry Valleys of the harsh, icy continent, keeps from freezing because of its salt-rich composition. But why this landlocked...

Intense Rainfall In The Ebro Basin Is Becoming Less Frequent
2013-02-05 11:25:23

FECYT - Spanish Foundation for Science and Technology Researchers from CSIC's Aula Dei Experimental Station in Zaragoza, Spain have confirmed that the frequency of intense rainfall has been decreasing in the Ebro basin since 1955. Despite what it may seem, intense rain is becoming rarer in the Ebro basin according to two studies carried out by Spanish researchers from the Department of Soil and Water of CSIC's Aula Dei Experimental Station in Zaragoza. Their results have been published...

Understanding how our water catchments react to natural disturbances, may offer hydrologists greater insight into how to manage our water supplies. Key to this, is an understanding of the steady state and why water responds differently in different circumstances. Dr Tim Peterson, from the School of Engineering at the University of Melbourne has offered new theories that will lead to a deeper knowledge of how water catchments behave during wet and dry years. His research was published...

Clean Water Systems & Stores Inc has released a new free guide for drought stricken areas of North America that details how homeowners and business that rely on well water can cut the amount of waste water being produced by their water softeners and automatic filter systems. Santa Cruz, CA (PRWEB) January 23, 2013 According to the The National Integrated Drought Information System, the 2013 American Drought is a record-breaking expansion of the drought that started in 2010, after the...

There Is A Limit For How Long Plants Can Adapt To Drought
2013-01-23 13:50:15

University of Arizona Plants can adapt their demand for water depending on how much is available - However, this resilience has a limit, and prolonged drought conditions threaten the survival of plant communities, especially in more arid areas Scientists with the U.S. Department of Agriculture, or USDA, and their partners have determined that water demand by many plant communities can fluctuate in response to water availability, indicating a capacity for resilience even when changing...

Plant Water Demands Shift With Water Availability Confirmed By USDA Study
2013-01-22 13:59:07

U.S. Department of Agriculture (USDA) Plants can adapt to extreme shifts in water availability, such as drought and flooding, but their ability to withstand these extreme patterns will be tested by future climate change, according to a study by U.S. Department of Agriculture (USDA) scientists and their cooperators. The study was published this week in Nature by a team of Agricultural Research Service (ARS) scientists led by Guillermo Ponce Campos and Susan Moran and an Australian...

Endorheic Basin
2013-04-18 22:40:14

An endorheic basin, from the Ancient Greek endon, meaning “within” and rhein, meaning “to flow”, is a closed drainage basin that holds onto water and does not allow outflow to other external bodies of water, such as oceans or rivers, but joins instead into lakes or swamps, seasonal or permanent, that equilibrate via evaporation. Basins such as these might also be referred to as closed or terminal basin or as internal drainage systems. Usually, water that has built up in a drainage...

A drainage divide, water divide, divide, or watershed is the line that separates neighboring drainage basins. In flat country the divide may be invisible (just a notional line on the ground either side of which water starts its journey to different waterways). While, in hilly country, the divide lies along peaks and ridges. Drainage divides are important geographical, and sometimes political boundaries. Roads and railways often follow divides to minimize slopes and marshes and rivers....

The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...

Environmental Science

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...
