pygmy phenotype
2014-08-21 03:00:37

A'ndrea Elyse Messer, Penn State The small body size associated with the pygmy phenotype is probably a selective adaptation for rainforest hunter-gatherers, according to an international team of researchers, but all African pygmy phenotypes do not have the same genetic underpinning, suggesting a more recent adaptation than previously thought. "I'm interested in how rainforest hunter-gatherers have adapted to their very challenging environments," said George H. Perry, assistant professor...

Ineffective Management Causing Tropical Grassy Ecosystems To Be Threatened
2014-03-13 14:50:41

University of Liverpool Tropical grassy areas in India, Australia, and South America store around 15% of the world’s carbon Scientists at the University of Liverpool have found that tropical grassy areas, which play a critical role in the world’s ecology, are under threat as a result of ineffective management. According to research, published in Trends in Ecology and Evolution, they are often misclassified and this leads to degradation of the land which has a detrimental effect...

Mountainous Ecosystems Acted Like A Thermostat For Millions Of Years
2014-02-06 14:21:46

University of Oxford For the first time, scientists have discovered how tree roots in the mountains may play an important role in controlling long-term global temperatures. Researchers from Oxford and Sheffield Universities have found that temperatures affect the thickness of the leaf litter and organic soil layers, as well as the rate at which the tree roots grow. In a warmer world, this means that tree roots are more likely to grow into the mineral layer of the soil, breaking down rock...

Fungi Plays Role As Rainforest 'Diversity Police'
2014-01-23 12:54:43

University of Oxford The Oxford University-led research found that fungi regulate diversity in rainforests by making dominant species victims of their own success. Fungi spread quickly between closely-packed plants of the same species, preventing them from dominating and enabling a wider range of species to flourish. "In the plant world, close relatives make bad neighbours," said Dr Owen Lewis of Oxford University's Department of Zoology, who led the study. "Seedlings growing near...

Plant Mapping Project Highlights Where Rarest Species Thrive
2013-10-17 15:35:22

Lee Rannals for redOrbit.com - Your Universe Online An international group of researchers has created the most comprehensive map of rare plants to date. The new map, published in Ecology Letters, shows how climate stability plays a crucial role in the distribution of plants on Earth. It shows that rare species in the Americas are located in California, Mexico, the Caribbean islands, parts of the Andes mountains, the south of South America, and the region around Rio de Janeiro. "This...

Scientists Turn To The Phonebook To Name 101 New Beetle Species
2013-03-28 09:33:58

April Flowers for redOrbit.com - Your Universe Online Tropical rainforests are known to harbor a high biodiversity of untold species, many of them unknown and unnamed by scientists as of yet. Insects, especially beetles, make up a large proportion of this undiscovered life on Earth. Experts in remote tropical countries' fauna such as the wilderness of New Guinea, Alexander Riedel of the Natural History Museum Karlsruhe (SMNK) and Michael Balke of the Zoological State Collection Munich...

Amazon Deforestation Threatens Microbial Life
2012-12-25 05:22:39

April Flowers for redOrbit.com - Your Universe Online A troubling loss of diversity among the microbial organisms responsible for a functioning ecosystem is accompanying deforestation in the Amazon rainforest, an international team of microbiologists led by the University of Massachusetts, Amherst, has discovered. "We found that after rainforest conversion to agricultural pastures, bacterial communities were significantly different from those of forest soils. Not only did the pasture...

Plants´ ability to absorb increased levels of carbon dioxide in the air may have been overestimated, a new University of Minnesota study shows. The study, published this week in the journal Nature Climate Change, shows that even though plants absorb large amounts of carbon dioxide and actually can benefit from higher levels of it, they may not get enough of the nutrients they need from typical soils to absorb as much CO2 as scientists had previously estimated. Carbon dioxide...

Scientists at Aarhus University have spearheaded research results that shed new light on the processes forming the composition of species assemblages in the tropics Scientists at Aarhus University have spearheaded research results that shed new light on the processes forming the composition of species assemblages in the tropics. "It comes as a surprise to us that climate change over millions of years still leaves a signature in the composition of species assemblages we see today. If...

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...

The Amazon Rainforest (known as Floresta Amazônica or Amazônia in Portuguese, and Selva Amazónica or Amazonia in Spanish), also known as Amazonia, or the Amazon Jungle, is a moist broadleaf forest that covers almost all of the Amazon Basin in South America. The basin consists of 1.7 billion acres, of which 1.4 billion acres is rainforest. This rainforest covers nine nations (Brazil, Peru, Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana). Brazil contains...

Deforestation
2009-05-27 18:12:50

Deforestation is the act or process of removing trees from forested lands by cutting or burning. There are many reasons for deforestation. Logs are sold as a commodity and cleared lands can be used for pastures and human settlements. The damage caused by deforestation, however, can be great. If land is not somewhat reforested it can cause damage to habitats for wildlife and other plant life, affect the aridity of the region, and possibly encourage degradation into wasteland. Due to negligent...
