[Global Warming: Man or Myth?] Climate Change Impact on Oceans & Shallow Seas « Global Warming ...: Organisms are moving towards higher latitudes and are causing massive changes in ecosystems as they do.  There are also numerous examples of novel communities within ecosystems that are popping up which have no known precedent. For example, the black spined sea urchin has migrated south from New South Wales and is increasingly removing Tasmania’s kelp forests and replacing them with “barrens”.  Another examples include the spread of the oyster parasite Perkinsus marinus across a 500-km range of the northeastern United States during pronounced warming in 1990 and 1991  and the temperature susceptibility of red abalone in California to a fatal rickettsial infection (Ibid).

[Wired.co.uk RSS] Can ecosystem engineering prevent ecological catastrophe?: In Tucson, those ignored habitats are backyards, schoolyards and the mosaic of neighbourhoods and businesses typical of America’s suburban sprawl. Rosenzweig wants to arrange their habitats with a program built on a database of life-history characteristics on 300 local plant species, plus natural history records gathered from a century of research on Tumamoc Hill, an 870-acre island of relatively undisturbed desert west of downtown.

[The Lost Girls] Florida Keys Marine Ecosystem: Ride Safely Through Blue Rider ...: In fact, many irresponsible recreational riders aren’t aware of their boating obligation to get up to speed on this unique habitat.  And their riding is one of the main causes of habitat loss or damage and endangered species. From scarring seagrass beds to stirring up the ocean floor, and from tearing up plant life to hitting water animals, irresponsible boaters unfortunately make their irreversible mark.

[TreeHugger] Hawaiian Coral Saved by Freezing Sperm : TreeHugger: As corals face a daily bashing through warm, polluted waters, the scientists at University of Hawaii at Manoa and the Smithsonian Institution are building up a bank of frozen sperm and embryos of Hawaiian coral species, just in case. The diversity of coral species is vital to Hawaii's marine ecosystems, providing the habitat necessary for the survival of the myriad of fish, crustacean and plant species around the islands.

[Consortium for Ocean Leadership] Creation of the First Frozen Repository for Hawaiian Coral: Saving reef habitat alone will not stop corals' decline because many of the most serious threats are global rather than local. Done properly over time, researchers can store samples of frozen material and place them back into ecosystems to infuse new genes and vigor into natural populations, thereby enhancing the health and viability of wild stocks.

[Care2 News Network] Protect Marin County's San Geronimo Valley Ecosystem ! TAKE ...: It directly impacts tens of thousands of Marin residents and millions of other Americans who annually visit Samuel P. Taylor State Park, National Park Service lands, and Tomales Bay, who come to enjoy our common public resources that include viewing salmon, and being able to have their children swim and play in and along the Lagunitas Creek that is not degraded by the documented dangerously high levels of fecal coliform, sediment and nutrients from failed septic systems, and poor land use practices occurring in the San Geronimo Valley.

[Global Warming: Man or Myth?] Climate Change Impact on Freshwater Wetlands, Lakes & Rivers ...: Significant climatic changes, which most scientists agree are now driven primarily by human-generated greenhouse gases, are already under way in the Champlain Basin: mean annual air temperatures warmed by 2.1°F (1.2°C) between 1976 and 2005, with the most significant seasonal warming during summer and autumn.  Total annual precipitation during that time period was approximately 3 inches greater than it was during the preceding 8 decades.  Freeze-up on Lake Champlain is happening two weeks later than in the early 1800s””that is, in the increasingly rare winters when ice covers the main body of the lake at all.  Rising surface water temperatures may increase the stability and duration of warm-season stratification in Lake Champlain, potentially making the lake more susceptible to nuisance phytoplankton blooms and low-oxygen (“hypoxic”) conditions.

[Davtra's Blog] Biodiversity: Its Importance and the Global Conservation Resource ...: Wilson and his team in 2007 developed a framework that offers an improvement over approaches that only focus on land acquisition or species richness and do not account for threats. They discovered that one could protect many more plant and vertebrate species by addressing specific threats, such as invasive species control, than by relying solely on the acquisition of land for protected areas.

[Greenopolis: LiteGreen Blog] Butterflies, Bees Most Important To Ecosystem Survival ...: You can earn points by recycling in our Greenopolis Recycling Kiosks, blogging and commenting on Greenopolis and by recycling at home in selected cities. These points can then be traded in on coupons for meals, entertainment, discounts and more.

[Pakcikayo The Blog] Wetland Ecosystem Conservation: A Review | Pakcikayo The Blog: For example, Lindeman (1942) defined ecosystems as “…the system composed of physical, chemical, and biological processes active within a space/time unit.” Regardless of whether the emphasis is on biotic components or abiotic characteristics and processes of ecosystems, both remain integral to the concept of ecosystem. Rowe (1961) emphasized this when he defined ecosystems as “…a three dimensional segment of the earth where life forms and the environment interact.”

[Info] Ecologist Job Description, Education and Training Requirements ...: Like most of the other environmental careers, the professional field of ecology did not really grow popular until the late 1960s and early 1970s. Before then, some scientists and others had tried to warn the public about the ill effects of industrialization, unchecked natural resource consumption, overpopulation, spoiling of wilderness areas, and other thoughtless misuse of the environment.

[TreeHugger] New Research Claims Woolly Mammoths Were Killed Off by... Trees ...: There's always been uncertainty about what caused the extinction of the iconic woolly mammoth. One of the leading hypotheses so far was that humans were a primary cause of their decline because of over-hunting and competition for land, but new research by scientists at Durham University is challenging that view.

[India Current Affairs] India Current Affairs » Blog Archive » PROTECTION OF WILDLIFE AND ...: viii.                        The Centrally Sponsored Scheme of ‘Integrated Development of Wildlife Habitats’ was modified in 2008 to accord better protection and conservation to wildlife in the country by adding two new components to the existing components viz’Protection of Wildlife outside Protected Areas’

[NewWest.Net All Headlines] It's Disney Vs. Rangeland Destruction in Nevada's Wildlife Refuges ...: The genetic relationship of modern horses and their ancestors that went extinct really doesn't matter and neither does what caused that extinction. What matters is that the plant communities in Western North America went through radical changes since the last ice age about 13000 years ago in response to a significantly warmer and dryer climate and that rapid evolution was under a regime without horses.
