NASA Satellites Calculate Damage Of Previously Undiscovered Amazon Wildfires
2013-06-09 07:46:38

redOrbit Staff & Wire Reports — Your Universe Online A previously undetected type of wildfire occurring in the Amazon region is responsible for far more rainforest loss than deforestation in recent years, NASA scientists have discovered using innovative new satellite techniques. Known as “understory fires,” these wildfires have long remained undetected because they are located below the forest treetops, explained Tamarra Kemsley of Nature World News. However,...

Fires Burning In Northern Saskatchewan
2013-06-07 14:21:15

NASA NASA's Aqua satellite collected this natural-color image with the Moderate Resolution Imaging Spectroradiometer, MODIS, instrument on June 05, 2013. Actively burning areas, detected by MODIS´s thermal bands, are outlined in red. All three fires noted here are more than 100 hectares in size (>247 acres). According to the Government of Saskatchewan's wildfire website, this area of the province has been designated an "observation zone." This means in this area there are fewer...

Amazon Tree Seeds Become Smaller, Weaker Because Of Bird Decline
2013-05-31 11:39:54

April Flowers for redOrbit.com - Your Universe Online Over the last century, the disappearance of large, fruit-eating birds from the tropical forests of Brazil has caused the region´s forest palms to produce smaller, less successful seeds, according to an international team of researchers. The findings, published in Science, provide evidence that human activity can trigger fast-paced evolutionary changes in natural populations. Mauro Galetti, biological sciences professor from the...

A new study, published 28 May in the open access journal PLOS Biology, has revealed the potential importance of rare species in the functioning of highly diverse ecosystems. Using data from three very different ecosystems–coral reefs, tropical forests and alpine meadows–a team of researchers led by David Mouillot at the University of Montpellier 2, France, has shown that it is primarily the rare species, rather than the more common ones, that have distinct traits involved in...

Determining How Nature's Benefits Link To Human Well-being
2013-05-23 12:16:52

Michigan State University What people take from nature — water, food, timber, inspiration, relaxation — are so abundant, it seems self-evident. Until you try to quantitatively understand how and to what extent they contribute to humans. In today's world, where competition for and degradation of natural resources increases globally, it becomes ever more crucial to quantify the value of ecosystem services — the precise term that defines nature's benefits, and even more...

IUCN Develops New Red List For Endangered Ecosystems
2013-05-09 13:06:08

Brett Smith for redOrbit.com - Your Universe Online The International Union for Conservation of Nature (IUCN) Red List is widely considered to be the most comprehensive inventory of endangered and threatened species and the international organization is currently developing a similar list for the world´s fragile ecosystems. A new study in the open-access journal PLoS ONE, lays out a foundation of criteria for the list and applies these criteria to 20 ecosystems around the world....

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...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
