(01/27/2009) While deforestation garners more attention from environmentalists, fragmentation of forest habitats is of significant concern to ecologists. As forest is fragmented into islands by logging, roads, agriculture, and other disturbances, edge effects alter the structure, microclimate and species composition of the forest patches, usually reducing the overall number of species. Forest specialists are most likely to suffer, losing out to "weedier" generalists and species that can tolerate forest "edge" conditions. A new study, conducted in the Brazilian Amazon, takes a detailed look at the types of birds that are likely to persist, and even thrive, in forest fragments.
How to save the Amazon rainforest
(01/04/2009) Environmentalists have long voiced concern over the vanishing Amazon rainforest, but they haven't been particularly effective at slowing forest loss. In fact, despite the hundreds of millions of dollars in donor funds that have flowed into the region since 2000 and the establishment of more than 100 million hectares of protected areas since 2002, average annual deforestation rates have increased since the 1990s, peaking at 73,785 square kilometers (28,488 square miles) of forest loss between 2002 and 2004. With land prices fast appreciating, cattle ranching and industrial soy farms expanding, and billions of dollars' worth of new infrastructure projects in the works, development pressure on the Amazon is expected to accelerate. Given these trends, it is apparent that conservation efforts alone will not determine the fate of the Amazon or other rainforests. Some argue that market measures, which value forests for the ecosystem services they provide as well as reward developers for environmental performance, will be the key to saving the Amazon from large-scale destruction. In the end it may be the very markets currently driving deforestation that save forests.
Rancher accused of ordering murder of American nun is arrested in Brazil

20 years ago the Amazon lost its strongest advocate
(12/22/2008) Twenty years ago ago today, Chico Mendes, an Amazon rubber tapper, was shot and killed in front of his family at his home. He was 44. His assassination in Xapuri, a remote town in the Brazilian state of Acre, would serve as a catalyst that led to the birth of the movement to protect the Amazon rainforest from loggers, ranchers, and developers. But the movement has stalled. Some would even say it has failed: since 1988 more than 348,000 square kilometers (134,000 square miles) of Amazon rainforest have been leveled.
Amazon rainforest damage surges 67% in 2008
(12/20/2008) The area of rainforest in the process of being deforested — razed but not yet cleared — surged in the Brazilian Amazon during 2008, according to new figures released by Brazil's National Institute for Space Research (INPE). The announcement comes shortly after the Brazilian government reported a 4 percent increase in forest clearing for the year. Using an advanced satellite system that tracks changes in vegetation cover INPE found that 24,932 square kilometers of Amazon forest was damaged between August 2007 and July 2008, an increase of 10,017 square kilometers -- 67 percent -- over the prior year. The figure is in addition to the 11,968 square kilometers of forest that were completely cleared, indicating that at least 36,900 square kilometers of forest were damaged or destroyed during the year. The sum does not include areas that may have been selectively logged for commercial timber.

Lula pledges big cuts in Amazon deforestation -- after he leaves office
(12/12/2008) Last week Brazil unveiled plans to cut deforestation substantially from a 1996-2005 baseline of 19,533 square kilometers per year. The announcement met a mixed response from conservationists. Some applauded the decision to set hard targets for reducing deforestation, others say the targets were too low and that the country should aim for zero net deforestation by 2015. Nevertheless as more details have emerged, it becomes clear that the onus for reining in deforestation falls on Brazilian President Luiz Inacio Lula da Silva's successor.
In Poznan, France pushes initiative to save rainforests
(12/08/2008) As talks for incorporating forest conservation into an international climate treaty stall in Poznan, Poland due to technical debates, France has proposed an aggressive effort to address deforestation and forest degradation through the establishment of a Global Forest Carbon Mechanism (GFCM) and potential inclusion of forestry projects in the E.U.'s emissions trading scheme (ETS) beginning in 2013.

Tropical dry forest fragments important to conserving reptile biodiversity in Colombia
(12/01/2008) An important task in tropical conservation is to understand which species are particularly vulnerable to extinction, and identify the characteristics that put them at risk. Because habitat loss and fragmentation are at the root of the global extinction crisis, an extensive collection of literature has developed around profiling species assemblages in fragmented landscapes. It is also clear that species may respond differently to fragmentation, but many species experience direct or indirect negative effects, sometimes resulting in local extirpation in habitat patches.
Lack of information may slow conservation response to amphibian crisis
(12/01/2008) The Neotropics harbor between 30-50% of the world's reptiles and amphibians, but dramatic declines in both groups have been observed over recent decades. While a number of factors have been cited, many of the causes of reptile and amphibian declines are still poorly understood. The situation is paralleled by a lack of information of the natural history, ecology, and behavior of many species.
The number of endangered amphibians in Peru may be underestimated

Breakthrough may enable reforestation using mahogany
(10/16/2008) Brazilian researchers are closer to developing a way to establish large-scale mahogany plantations, reports the ITTO in its bi-monthly update. Scientists at the Federal Rural University of Amazonia (UFRA) have found that planting a matrix of mahogany with cedar reduces the incidence of the Hypsipyla grandella caterpillar, a chief pest of mahogany that has doomed previous attempts to reforest with the valuable hardwood species.
UK government: rainforests are weapon against global warming
(10/15/2008) Protecting tropical forests will simultaneously reduce carbon emissions, support poverty reduction and help preserve biodiversity and other forest services, says a new report commissioned by the British government. The report — dubbed the "Eliasch Review" after the lead author, Johan Eliasch, a multimillionaire Swede who runs a sports equipment company and owns 162,000 hectares (400,000 acres) of rainforest in the Brazilian Amazon — takes a comprehensive look at the role forests can play in mitigating climate change. It concludes: "Urgent action to tackle the loss of global forests needs to be a central part of any future international deal on climate change"

Slowing global economy will reduce Amazon deforestation
(10/08/2008) The global financial crisis will likely slow forest clearing in the Amazon rainforest, said Brazil's environment minister. Falling commodity prices combined with tighter credit and increased aversion to risk will undermine the economics of activities — including logging and agricultural expansion — that are key drivers of deforestation in the Brazilian Amazon. Forest clearing in the region has shown an increasingly tight correlation to beef and soy prices in recent years. Both products are produced on cleared rainforest lands.
Forest corridors key to maintaining biodiversity in fragmented landscape
(10/07/2008) Alta Floresta, a region in the Brazilian Amazon state of Mato Grosso, has experienced one of the highest deforestation rates on the planet since the mid-1980s due to the influx of colonists and ranchers who converted nearly half the region's forest land to pasture and agricultural plots. The change has had significant ecological impacts, including reducing the availability of water, increasing the incidence of forest fires, fragmenting remaining forest cover, and diminishing the quality of habitat for wildlife.
Good news for amphibians: three new species and one "extinct" frog discovered
(10/01/2008) Amphibians have received a lot of bleak news recently. Last week a report from the Zoological Society of London and EDGE stated that 50 percent of Europe’s amphibians will go extinct by 2050 unless more is done for their conservation. Meanwhile a report published in August found that one in three amphibians worldwide are threatened with extinction, while 200 species have already been lost since the 1980s. Therefore the discovery of three new frog species and the rediscovery of one thought to be extinct provide a little respite from such bad tidings.
