(07/02/2009) This is by no means a new battle: in fact, Tasmanian industrial foresters and environmentalists have been fighting over the issue of clearcutting the island’s forests for decades. The battle—some would probably prefer 'war'—is over nothing less than the future of Tasmania. Some Tasmanians see the rich forests that surround them in terms of income, dollars and cents; they see money literally growing on trees, or more appropriately growing on monoculture plantations and government owned native forests. They see the wilderness of Tasmania as an exploitative resource.
(06/29/2009) Often we hear about endangered species—animals or plants on the edge of extinction—however we rarely hear about endangered environments—entire ecosystems that may disappear from Earth due to humankind’s growing footprint. Tropical dry forests are just such an ecosystem: with only 2 percent of the world’s tropical dry forest remaining it is one of the world’s most endangered ecosystems. A newly established organization, the Azuero Earth Project, is working not only to preserve some of the world’s last tropical dry forest on the Azuero peninsula in Panama, but also to begin restoration projects hoping to aid both the forest’s viability and the local people. Edwina von Gal, a landscape designer, is one of the founders of the Azuero Earth Project, as well as president of the organization.
(06/25/2009) The first global study of open ocean (pelagic) sharks and rays found that 32 percent of the species are threatened with extinction largely due to overfishing and bycatch, making pelagic sharks and rays more threatened than birds (12 percent), mammals (20 percent), and even amphibians (31 percent), which are considered to be undergoing an extinction crisis. The situation worsens when only sharks taken in high-seas fisheries are considered: 52 percent of these species are threatened.
(06/25/2009) Between 1700 and 1850 forest cover in India and China plummeted, falling from 40-50 percent of land area to 5-10 percent. Forests were cut for agricultural use across Southeast Asia to feed a growing population, but the changes from forests to crops had unforeseen consequences. A new study published in the Proceedings of the National Academy of Sciences links this deforestation across Southeast Asia with changes in the Asian Monsoon, including significantly decreased rainfall.
(06/24/2009) The theory of shifting baselines was first elucidated by scientists exploring urban children’s perception of nature in 1995. In the same year, marine biologist Daniel Pauly coined the term ‘shifting baselines’. Since then the idea of humans perceiving nature inaccurately, through ‘shifting baselines’, has taken the conservation world by storm: the theory appeared to describe a commonly noticed problem regarding people’s view of the natural world around them. However, the theory had yet to be tested in a scientific manner: were people actually undergoing shifting baselines or was something else going on? For the first time a new paper in Conservation Letters empirically tests the shifting baselines theory.
(06/23/2009) A lot of time, effort, and funds have been spent on programs evaluating the threat of extinction to species around the world. Yet insects have not benefited from these programs, which have largely focused on more 'charismatic' species such as mammals, birds, amphibians, and reptiles. This gap is clearly shown by the fact that 42 percent of vertebrates have been assessed by the International Union for the Conservation of Nature (IUCN), and only 0.3 percent of invertebrates.
(06/22/2009) Evolution is often thought of being a slow-process, taking thousands, if not millions, of years. However a new study in The American Naturalist found that Trinidadian guppies underwent evolution in just eight years, or thirty generations. Less than a decade ago Swanne Gordon, a graduate student at UC Riverside, and her team introduced Trinidadian guppies into the Damier River in the Caribbean island of Trinidad. They placed the guppies above a waterfall to allow them to flourish in a largely predator-free environment.
(06/21/2009) The decades-long conflict in Cambodia devastated not only the human population of the Southeast Asian country but its biodiversity as well. The conflict led to widespread declines of species in the once wildlife-rich nation while steering traditional society towards unsustainable hunting practices, resulting in a situation where wildlife is still in decline in Cambodia, according to a new study from researchers with the World Wildlife Fund (WWF).
(06/18/2009) While the use of synthetic fertilizer has greatly increased agricultural production globally—helping to feed a global population that is not slowing down—it has brought with it high environmental costs. Fertilizer runoff has polluted many coastal regions creating ‘dead zones’ where the ocean is starved of oxygen by the influx of nitrogen. Synthetic fertilizers have also polluted the air with ammonia, and sent emissions of nitrous oxide into the atmosphere, contributing to global warming.
(06/17/2009) Government officials and scientists released a 196 page report detailing the impact of global warming on the U.S. yesterday. The study, commissioned in 2007 during the Bush Administration, found that every region of the U.S. faces large-scale consequences due to climate change, including higher temperatures, increased droughts, heavier rainfall, more severe weather, water shortages, rising sea levels, ecosystem stresses, loss of biodiversity, and economic impacts.
(06/16/2009) Near the once-contentious border of Ecuador and Peru in the mountainous forests of the Cordillera del Condor, scientists from Conservation International (CI) conducted a Rapid Assessment Program (RAP), uncovering what they believe are several new species, including four amphibians, one lizard, and seven insects. The team focused on the Upper Nanharitza River Basin, which has been geologically isolated from the rest of the Andes, giving it broad potential for new species.
(06/16/2009) It could be a plot of a (bad) science-fiction film: a man-made disaster creates spawns of millions upon millions of jellyfish which rapidly take over the ocean. Humans, starving for mahi-mahi and Chilean seabass, turn to jellyfish, which becomes the new tuna (after the tuna fishery has collapsed, of course). Fish sticks become jelly-sticks, and fish-and-chips becomes jelly-and-chips. The sci-fi film could end with the ominous image of a jellyfish evolving terrestrial limbs and pulling itself onto land—readying itself for a new conquest.
(06/14/2009) The first ever comprehensive survey of caribou worldwide (known as reindeer in Europe) has found that the species has suffered a staggering decline. Researchers from the University of Alberta discovered that the caribou population has fallen 60 percent in half as many years. The study published in Global Change Biology points to global warming and industrial development as the reasons behind the decline.
(06/11/2009) A new species of moth with brilliantly-colored pink wings has been discovered at 7,700 feet in the Chiricahua Mountains of southern Arizona. "This large moth flew in and we didn't think much of it because there is a silk moth very much like it, a Doris silk moth that feeds on pines that has dark wings with pink on the hind wings. It's fairly common there," said University of Arizona biologist, Bruce Walsh, who discovered the species.
(06/11/2009) The Wildlife Conservation Society (WCS) announced yesterday the discovery of eastern lowland gorilla nests in an unexplored area of the Democratic Republic of Congo (DRC), expanding the range of this little-known subspecies by 30 miles (50 kilometers). The eastern lowland gorilla, also known as Grauer’s gorilla, is currently listed as Endangered in the IUCN Red List. Scientists estimate that the gorilla has as few as 8,000 individual left. Although closely related to mountain gorillas, the eastern lowland gorilla is the world’s largest living primate, weighing over 500 pounds at maximum, and is endemic to the DRC.
(06/10/2009) Three different species of frogs have been discovered living in the dung of the Asian elephant in southeastern Sri Lanka. The discovery—the first time anyone has recorded frogs living in elephant droppings—has widespread conservation implications both for frogs and Asian elephants, which are in decline. "I found the frogs fortuitously during a field study about seed dispersal by elephants," Ahimsa Campos-Arceiz, a research fellow from the University of Tokyo, told Monagaby.com.
(06/10/2009) Researchers from the British Antarctic Survey (BAS) have uncovered a novel way to locate the world’s largest penguin’s breeding sites, employing satellite imagery they seek out Emperor penguin guano, droppings which show up starkly on the otherwise unsullied white sea ice of Antarctica. Searching for the penguins themselves had proven too difficult, since the birds’ black-and-white coloring allowed them to blend in with the shadows made by the ice. The penguin droppings however are light-brown—a colors that has no other source on sea ice, besides guano.
(06/09/2009) It has been estimated that Afghanistan only has 100 snow leopards left, however photos from camera traps placed by the Wildlife Conservation Society (WCS) show that there may be hope for snow leopards in the war-torn nation after all. Working in Afghanistan’s Wakhan Corridor, WCS set up five camera traps. Four of the five camera traps took photos of snow leopards, including 22 images in total.
(06/09/2009) The 2009 IUCN Red List for birds broke records by listing more Critically Endangered birds than ever before. Despite this, there were individual species that bucked the global trend: Lear’s Macaw Anodorhynchus leari, a bright blue parrot from northeastern Brazil, was one of these. Due to effective conservation measures the parrot’s population has reached nearly a thousand birds (up from a low of just a hundred individuals in 1989), and therefore was moved down the list, from Critically Endangered to Endangered.
(06/08/2009) After highly-publicized poisonings of lions in Kenya’s national parks, the Kenyan Parliament has begun addressing longstanding concerns regarding the pesticide Furadan. Since 1995 Furadan has been used to illegally kill 76 lions, 15 hyenas, 24 hippos, over 250 vultures, and thousands of other birds in Kenya. These numbers are likely low due to under-reporting, according to Kenya-based conservation organization, 
(06/08/2009) In April marine scientist Jennifer Jacquet made the case on her blog Guilty Planet that people should abstain from eating seafood to help save life in the ocean. With fish populations collapsing worldwide and scientists sounding warnings that ocean ecosystems—as edible resources—have only decades left, it is perhaps surprising that Jacquet’s call to abstain from consuming seafood is a lone voice in the wilderness, but thus far few have called for seafood lovers to abstain.
(06/08/2009) Individual bats have the ability to tell the difference between other bats just by the sound of their voice, according to a study published in PLoS Computational Biology. Researchers from the University of Tuebingen, Germany found that the greater mouse-eared bat could distinguish between their fellows’ echolocation calls. A subject bat was tested by having to select between two others depending on their calls. The subject bats chose correctly over 80 percent of the time.
(06/08/2009) Thirty-three species are included in Afghanistan’s first-ever listing of protected wildlife. Well-known animals like the snow leopard, wolves, and brown bears received full legal protection from hunting and harvesting alongside lesser-known species like the paghman salamander, goitered gazelle, and Himalayan elm tree. The protected species list consists of twenty mammals, seven birds, four plants, one amphibian, and one insect.
(06/04/2009) The cuckoo bird is famous for its parental strategy: rather than raise its own children it infiltrates the nest of an unsuspecting bird of a different species, replacing that bird’s eggs with its own; when the cuckoo babies are born the ‘adoptive’ parents end up unwittingly rearing young that is not theirs. However, at least one bird species—the reed wabler—has learned to defend itself against such clever incursions.
(06/03/2009) Watch any nature documentary and it’s sure to include pulse-pounding footage of large herbivores migrating across African plains, Asian steppe, or the Arctic tundra. The images have become iconic: wildebeest forging a crocodile-inhabited river, caribou breaking through snow fields, Saiga running over tall grass. Despite such images of plenty, migrations are declining across the world, and in six cases have disappeared entirely.
(06/02/2009) As Africa’s birds are forced to move habitats due to climate change, a new study finds that the continent’s current park system will continue to protect up to 90 percent of bird species. "We looked at bird species across the whole network of protected areas in Africa and the results show that wildlife conservation areas will be essential for the future survival of many species of birds,” said Dr. Stephen Willis from Durham University. "Important Bird Areas (IBAs) will provide new habitats for birds that are forced to move as temperatures and rainfall change and food sources become scarce in the areas where they currently occur. Protected areas are a vital conservation tool to help birds adapt to climate change in the 21st century."
(06/01/2009) It is unlikely that world government will keep their pledge to protect 10 percent of every ecological region by 2010, according to a new study published in Biological Conservation. This goal is just one of many agreed upon by world governments through the Convention on Biological Diversity. With less than a year to the goal’s deadline, the study found that half of the world’s ecoregions are currently below the 10 percent threshold.
(05/31/2009) Restoration efforts can return polluted or degraded landscapes to previous states in less than a lifetime, according to study Yale School of Forestry and Environmental Studies. The study rebuts a common assumption that ecosystem recovery takes centuries, even millennia.
(05/31/2009) The European beaver has been reintroduced into a loch in western Scotland. Eleven individual beavers were released on Friday, May 29th by the Scottish Beaver Trial (SBT), a project run by the Scottish Wildlife Trust, the Royal Zoological Society of Scotland and the Forestry Commission Scotland. The beaver was hunted to extinction throughout Britain during the Middle Ages for its fur. The last record of a beaver in Britain was made in 1526.
(05/28/2009) Scientists have long recognized ‘coextinctions’ as a major concern when it comes to the current mass extinction crisis. Despite such recognition, however, the role of coextinctions remains largely mysterious and little-studied. A new paper attempts to address this by settling what is known (and unknown) about the phenomenon of coextinctions and where research needs to go next.
