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...

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...

In 2013, Alcoa Foundation and American Forests are partnering to plant 175,000 trees in 19 forest restoration projects around the globe. Washington, DC (PRWEB) June 05, 2013 On the United Nations World Environment Day, Alcoa Foundation and American Forests announce that through the Partnership for Trees Program, more than 175,000 trees will be planted across 19 global project sites this year. The Partnership for Trees Program is part of Alcoa Foundation´s commitment to plant 10...

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...

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...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
