Valuing Nature From Space
2013-07-11 15:51:19

ESA Satellites show how we can promote economic development in an environmentally sustainable manner by putting a price on nature's resources. Located on the Indonesian island of Lombok, the Mount Rinjani National Park is an important ecosystem for numerous endangered plants and animals. Just outside the park's boundaries, the fertile soils are exploited for agriculture and much of the forest has been cleared away for farmland. These farms are of great importance to the local...

Climate Change Threatens Survival Of Forests On Drier, Low-elevation Sites
2013-06-28 10:10:53

Oregon State University Predicted increases in temperature and drought in the coming century may make it more difficult for conifers such as ponderosa pine to regenerate after major forest fires on dry, low-elevation sites, in some cases leading to conversion of forests to grass or shrub lands, a report suggests. Researchers from Oregon State University concluded that moisture stress is a key limitation for conifer regeneration following stand-replacing wildfire, which will likely...

New research from the University of Guelph, published Tuesday in the journal Biodiversity and Conservation, says that allowing industrial extraction in a northern Ontario old-growth red pine forest – the largest remaining in the world – would significantly threaten biodiversity in Canada. The study says Wolf Lake Forest Reserve is a “scientifically irreplaceable system.” “Wolf Lake Forest deserves intensive study, monitoring and full protection from future development,” said...

Northern Biomass Of Earth Has Been Mapped And Measured
2013-06-26 07:53:13

ESA The biomass of the northern hemisphere’s forests has been mapped with greater precision than ever before thanks to satellites, improving our understanding of the carbon cycle and our prediction of Earth’s future climate. Accurately measuring forest biomass and how it varies are key elements for taking stock of forests and vegetation. Since forests assist in removing carbon dioxide from the atmosphere, mapping forest biomass is also important for understanding the global carbon...

Young Students Challenged To Catch Bugs
2013-06-24 07:44:59

ESA Spiders, beetles and worms might look creepy, but these creatures tell us a lot about biodiversity. Students are being challenged to count the creepy-crawlies’ eyes, legs and antennae and compare them with specimens found by astronauts on an underground adventure in September. Secondary-school students can get a taste of finding new life. Young explorers aged 12–14 are being asked to face some of the challenges of the CAVES training course, a mission that sends astronauts...

Effects Of Predators On Carbon Cycle
2013-06-18 09:44:57

April Flowers for redOrbit.com - Your Universe Online The predator-prey relationship can affect the flow of carbon through an ecosystem, according to a new study from the Yale School of Forestry & Environmental Studies. The findings, published in Proceedings of the National Academy of Sciences, may offer a new way of looking at biodiversity management and carbon storage for climate change. The study examines the relationship between grasshoppers (herbivores) and spiders (predators)...

Over the years ecologists have shown how biological diversity benefits the health of small, natural communities. New analysis by ecologists at UC Santa Cruz demonstrates that even higher levels of biological diversity are necessary to maintain ecosystem health in larger landscapes over long periods of time. Think of it as patches on a quilt, says Erika Zavaleta, UCSC associate professor of environmental studies. Each patch may be a diverse habitat of plants, animals, and insects but it is...

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.
