Image 1 - Climate Change To Blame For Dead African Trees
2011-12-12 10:20:24

Trees are dying in the Sahel, a region in Africa south of the Sahara Desert, and human-caused climate change is to blame, according to a new study led by a scientist at the University of California, Berkeley. "Rainfall in the Sahel has dropped 20-30 percent in the 20th century, the world's most severe long-term drought since measurements from rainfall gauges began in the mid-1800s," said study lead author Patrick Gonzalez, who conducted the study while he was a visiting scholar at UC...

Led by scientists at Woods Hole Research Center A new study released today in the EarlyView of Ecology Letters addresses forest productivity trends in Alaska, highlighting a shift in biomes caused by a warming climate. The findings, conducted by scientists at the Woods Hole Research Center and three other institutions based in Alaska and France, linked satellite observations with an extensive and unique tree-ring data set. Patterns observed support current hypotheses regarding increased...

From 1999 to 2009, an average of one new species of plant or animal was discovered every three days in the Amazon region, according to a report released Tuesday by environmental watchdog WWF. The report, which was entitled "Amazon Alive: A Decade of Discoveries 1999-2009" and compiled as part of the group's Living Amazon Initiative, "clearly shows the incredible diversity of life in the Amazon," Francisco Ruiz, the head of the project, said in a statement. As part of the Living Amazon...

Vegetation around the world is on the move, and climate change is the culprit, according to a new analysis of global vegetation shifts led by a University of California, Berkeley, ecologist in collaboration with researchers from the U.S. Department of Agriculture Forest Service. In a paper published today in the journal Global Ecology and Biogeography, researchers present evidence that over the past century, vegetation has been gradually moving toward the poles and up mountain slopes, where...

Having a large-scale boreal forest biomass inventory would allow scientists to understand better the carbon cycle and to predict more accurately Earth's future climate. However, obtaining these maps has been wrought with difficulty "“ until now. A new processing algorithm has been developed using stacks of images from the Advanced Synthetic Aperture Radar (ASAR) on ESA's Envisat satellite that allows for the retrieval of boreal forest biomass well beyond the levels that have been...

New study finds that the average ecosystem will need to shift about a quarter mile per year to keep pace with global climate change From beetles to barnacles, pikas to pine warblers, many species are already on the move in response to shifting climate regimes. But how fast will they - and their habitats - have to move to keep pace with global climate change over the next century? In a new study, a team of scientists including Dr. Healy Hamilton from the California Academy of Sciences have...

In the first systematic analysis of threats to the biodiversity of the world's mediterranean-climate regions, scientists at The Nature Conservancy and UC Davis report that these conservation hotspots are facing significant and increasing pressure. The study, which appears in this week's edition of the journal Diversity and Distributions, is part of a global conservation assessment of the rare mediterranean biome."Throughout human history, the mild climates of mediterranean regions have...

How best to map "Ëœboreal' or northern forest with spaceborne radar is the focus of an ESA campaign currently underway in northern Sweden. By answering this question, the campaign addresses one of the key objectives of the candidate Earth Explorer BIOMASS mission. BIOMASS is one of six candidate Earth Explorer missions that has just completed assessment study and will be presented to the science community at a User Consultation Meeting in January 2009. Up to three of the...

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...

Kazakh Uplands
2013-04-18 23:02:25

The Kazakh Uplands, known also as the Kazakh Hummocks, is a large peneplain formation that stretches throughout the central and eastern regions of Kazakhstan. It’s made up of low mountain oases and elevated plains, and contains large deposits of coal within the north and copper within the south. Rare species, such as the Asiatic Cheetah, may still reside in this region. Several notable cities, including the country’s capital, Astana, are located there. A portion of the Kazakh Uplands...

Oceania is one of Earth's eight ecozones. It is the smallest ecosystem found on the planet. Oceania is unique as it is the only ecosystem that does not include any continental land mass. This bioregion includes the Pacific Ocean islands of Micronesia, Fijian Islands, and most of Polynesia (except for New Zealand). This is also the youngest ecozone. While the other ecozones include fragments of ancient continents and land masses, Oceania is composed of volcanic islands and coral atolls that...
