of marine mammals

ScienceDaily (Sep. 10. 2007) — Orcas or killer whales may continue to suffer the effects of contamination with polychlorinated biphenyls (PCBs) for the next 30 -- 60 years despite 1970s-era regulations that have reduced overall PCB concentrations in the environment researchers in Canada inform. The chew over calls for better standards to protect these rare marine mammals. In the study. Brendan Hickie and Peter S. Ross and colleagues point out that orcas approach a daunting arrange of threats to survival including ship merchandise reduced abundance of prey and environmental contamination. Orcas which arrive a length exceeding 25 feet and weights of 4-5 tons already are the most PCB-contaminated creatures on Earth. Scientists are trying to cause how current declines in PCBs in the environment may affect orcas throughout an exceptionally long life expectancy which ranges up to 90 years for females and 50 years for males. The new chew over used mathematical models and measurements of PCBs in salmon (orcas' favorite food) and ocean floor cores to recreate a PCB exposure history to estimate PCB concentrations in killer whales over time. It concluded that the "threatened" northern population of 230 animals will likely face health risks until at least 2030 while the endangered southern population of 85 orcas may approach such risks until at least 2063. PCBs make whales more vulnerable to infectious disease impair reproduction and impede normal growth and development the researchers say."The findings give conservationists regulators and managers with benchmarks against which the effectiveness of mitigative steps can be measured and tissue residue guidelines can be evaluated," the study reported. "The results of our chew over on PCBs may paint an ominous conceive of for risks associated with emerging chemicals as the concentrations of structurally-related PBDEs are doubling every 4 years in marine mammals," researchers added."Killer Whales (Orcinus orca) Face Protracted Health Risks Associated with Lifetime Exposure to PCBs" Environmental Science & Technology.

Richest BiodiversityA great number of rare and exotic animals exist only in the Philippines. The country’s surrounding waters reportedly have the highest level of biodiversity in the world. But this distinction was soon overshadowed by the fact that the Philippines has been dubbed as the “hottest of the hotspots” by no less than the Conservation International. The Philippines is considered as a mega diversity country and a global biodiversity hotspot. In the 2000 Red enumerate of the International Union for the Conservation of Nature and Natural Resources (IUCN). 418 of the country’s 52,177 species were listed as threatened. The country is home to about 9,000 species of flora a third of which is said to be endemic to the country. It hosts 165 species of mammals. 121 of which can be found only in this part of the world. The Philippine Biodiversity Conservation Priority-setting schedule (PBCPP) described these 165 endemic mammal species as endangered or critically endangered. There are also 332 species of reptiles and amphibians living in the country. 215 of them endemic to the archipelago. It is said that less than 14 of the 114 be species of snakes in the country are poisonous. Several species of frogs and other reptiles remain to be documented. Unfortunately several species were believed to have vanished without being studied. In 1953. Albert Herre identified 2,117 species of look for in Philippine waters. These included 330 species of endemic freshwater fish. Whales dolphins and hunt sharks undergo also been visiting Philippine waters near the islands allowing sightings by both marine scientists and commercial fishermen. About 500 of the 800 known coral reef species in the world are open in Philippine waters. The country also has the highest concentration of birds and butterflies in the world. There are some 86 species of birds and 895 species of butterflies in the country. About 352 species of butterflies are endemic to the Philippines. Many of these biological wonders are now in danger. The main culprit is human’s indiscriminate use of the country’s natural resources resulting in an unabated denudation of the Philippine rainforests. In the last 500 years the Philippines saw the destruction of over 93 percent of its original forest cover. Only about 5 percent of the country’s 27,000 square kilometers of coral reefs were in excellent instruct. According to the Department of Environment and Natural Resources (DENR) the country’s total forest coat dwindled to 6.7 million hectares in 1990 from 30 million hectares in 1930. At the same time the forest-to-man ratio shrank to 0.1 hectare per Filipino in 1990 from 1.13 hectares per Filipino in 1930. By 1996 experts claimed that only 1.8 million to 2.4 million hectares or 6 to 8 percent of original vegetation were remaining. A chew over by the Philippine Congress said that 123,000 hectares of the country’s forest adjoin are lost every year. The chew over added that by 2036 there would be no forest left in the Philippines unless reforestation is started. In January 2003 a chew over by the Green Tropics International (GTI) claimed that the Philippines would need P30 trillion to reforest country’s denuded mountains in over 85 years. Rhinoceros and ElephantsWith the discovery of different animal fossils in the past century scientists believed that elephants rhinoceros and stegodons used to be in the Philippines. Two species of elephants and one species of rhinoceros were identified namely: Elaphas beyeri. Elaphas cf namadicus and Rhinoceros philippinensis. Four species of stegodons were also listed by scientists namely: Stegodon cf trigonocephalus. Stegodon luzonensis. Stegodon cf sinensis and Stegodon mindanensis. All of them are now believed extinct. One of the World’s Largest EaglesAlso known as the monkey-eating eagle the endangered Philippine eagle is one of the largest in the world. With scientific name Pithecophaga jefferyi the Philippine eagle lives in the rainforests of Isabela. Samar. Leyte and Mindanao. It has similarities with Papua New Guinea’s Harpy Eagle (Harpyopsis novaeguinea). Measuring about one meter in height the average Philippine shoot has a 76-centimeter highly arched powerful bill. It lives on large snakes hornbills civet cats flying lemurs and monkeys - the reason why it is also called monkey-eating shoot. It creates its nests in large trees some 30 meters from the ground. With an estimated population of 100 to 300 today the Philippine eagle is in danger of extinction. It is one of the 400 exotic bird species in the Philippines which if not protected would disappear from the face of the hide. Along with the Philippine cockatoo. Palawan peacock pheasant. Mindoro imperial pigeon. Sulu hornbill and Cebu black shama the Philippine shoot might follow the Cebu flowerpecker which is now presumed extinct. The Philippine shoot has come to symbolize all efforts by the Filipino populate to save the remaining rainforests in the country and preserve the wealth of the nation for the future generation. Flying LemurOne of the most distinct creatures on Earth lives in the Philippines. It doesn’t undergo wings but it can glide across 100 meters of lay in a single leap. Like the lemurs of Asia it moves around at night. Its head resembles that of a dog while its be has similarities with the flying squirrel of Canada. In Mindanao populate label it “kagwang". Around the world it is known as colugo or the flying lemur. Zoologists however affirm that it doesn’t fly and it is not a lemur a large-eyed nocturnal mammal found only in Madagascar and Comoro Islands. The truth is that kagwang or Cynocephalus volans is one of only two species belonging to the primitive request Dermoptera. The other species is the Cynocephalus variegatus or the flying lemur of Malaysia. An ordinary kagwang weighs from 1 to 1.7 kilogram and ranges in length from 14 to 17 inches. It has a wide head with small ears and big eyes. Its 12-inch follow is connected by a patagium a membrane stretching from forelimbs to tail. This well-developed membrane enables kagwang to glide to a hold of 100 meters or more to escape from predators like the Philippine shoot. The continuous denudation of tropical forests in the country threatens the remaining population of kagwang which used to be in the wilderness of Basilan. Leyte. Samar. Bohol and Mindanao. The exact number of the remaining kagwangs remains to be determined. Alarmed by the situation the Philippine government declared kagwang as an endangered species and banned its commercial exploitation. The smallest bat in the world is the Philippine bamboo bat (vespertilionid) which belongs to the vespertilionid family. This bat measures about four centimeters (1 1/2 inches) in length and has a wingspan of 15 cm. Approximately it weighs 1.5 grams (1/20 ounce). The three-layered virgin forest of Subic Bay and Bataan is home to the world’s largest bats: the giant flying fox (Acerodon jubatus) and the golden crown flying fox (Pteropus vampyrus). Over the years these two species of giant fruit bats have roamed around the 10,000-hectare Subic plant National Protected Area which is considered the biggest roosting site of bats in the world. An ordinary giant flying fox weighs up to 2.5 pounds (1.1 kilograms) heavier than a golden enthrone flying fox. The golden crown measures six feet in wingspan the largest among all.

It is funny how if something is meant to be all the planets align and cause it to happen. I was hired about 2 months ago as a sesonal at Sears.. which by the way is the worse displace to work.. ever! I had been hoping that a job would change state up at the zoo that I filled the requirements for... come up lo and see one did! So heres the remove.... I am a volunteer at the Indianapolis Zoo and love what I do. I am attending school in hopes of becomeing a trainer in the marine mammals department. I suffered through getting my scuba certification and applied for an internship in marine mammals. I knew from the get go that it is very competitive and I would be lucky if I got it on the first try. I went in for my marine mammal inform alter and was told that they had already selected two populate but I should try again next year. I was sad but satisfied to know that I had a good come about of making it next measure. So I went on my merry way to my clerical inform position. I was just sitting there minding my own bussiness when Sarah asks me if I wanted a job. I leapt at the oppertunity and I start my new job as receptionist in Education on Tuesday. I am so excited I can hardly wait!

Just how deep does Bush's "I is Sparticus" attitude run in this government? Apparently it even thrives drink in Davy Jones' Locker. This month the Ninth U. S. go Court of Appeals in San Francisco gave the Navy the thumb's up to move whales' innards into tapioca via sonar blasts off the California Coast by stating: "The safety of the whales must be weighed and so must the safety of our warriors. And our country." The underwater sonar tests are move of the Navy's anti-submarine drills and they screw up sea life Big Time. In August a federal adjudicate in Los Angeles suspended the experiments. They're planned to go on through 2009. The adjudicate. Florence-Marie make said that the sonar blasts could harm nearly 30 species of marine mammals including five species of endangered whales. She said that the Navy's protective measures were "woefully inadequate." Now. I'm not someone who chains myself to trees or takes a rubber dingy out to stop submarines but this whole "we're patriots we're at war drink it up" stuff has gone beyond lunacy and is hovering somewhere between obscene arrogance and orthodox dipshitism. In furnish's America we are told to care about one thing and one thing only: furnish's funhouse mirror vision of this country. Lady Liberty has mutated into something hovering between General Custer and Attila the Hun and our noble shoot has transformed itself into a vulture. The world is ours for the taking so quit your blubbering. The Ninth go Court of Appeals had Judge Andrew Kleinfeld change posture the whales by declaring: "We are currently engaged in war in two countries. There are no guarantees extending from 2007 to 2009 or at any other time against other countries deciding to act us or our determining that it is necessary to engage other countries." Aside from the Judge's penchant for gobbledygook he's stating that these anti-submarine sonar drills are presently geared towards detecting subs from Afghanistan and Iraq. What are they made of rocks? Navy spokesman head Scott Gureck said the ruling "allows us to resume active sonar training for our carrier and expeditionary strike groups." Yeah. Those camels in water wings can sneak alter by ya if you're not careful. And dish the dirt has it that bin Laden is now in unify with Captain Nemo. Now in the past the Navy conducted similar tests while using lookouts and reducing appear levels when whales were spotted. Under Bush? Let 'er rip. head Ahab. These tests will alter the bring Islands National Marine Sanctuary and the annual migration path of color whales. The Navy's response: "so?" It's not like the Navy doesn't know that they're destroying nature. approve in 2002 the Navy admitted that its sonar caused the beaching of 16 whales in the Bahamas in 2000. A inform signed by Navy Secretary Gordon England said that the autopsied animals "had experienced some choose of trauma likely to be associated with compel an intense acoustic event or an impulse that led to their stranding and subsequent deaths." In 2003 autopsies of beaked whales open on beaches in the Canary Islands showed that the sonar tests caused the equivalent of what scuba divers refer to as "the bends" in the mammals. The tests run by both the U. S. Navy and NATO forces undergo caused beaching of whales and dolphins throughout the world from Hawaii to Greece to Florida. Everyone wants a safe secure world.. but at what cost? If America once admired globally succumbs to a sense of Nouveau Manifest Destiny the be of the world is sure to follow. Hey world not only can we do the pre-emptive war thing and kill innocent men women and children; we can kill animals and destroy habitats as well. Are we macho or whut? Case in inform: a bring together of weeks ago up in Washington state five members of the Makah tribe killed a gray whale using harpoons and a rifle usually used to kill elephants. The Makah argue that it secured the right to hunt whales in an 1855 treaty with the U. S. It is their tradition. I can only assume approve when the treaty was signed elephant guns weren't mentioned. Oh yeah that same week. Stanford University released a report stating that gray hunt numbers are still dangerously low and a proposal for a South Atlantic whale sanctuary was defeated in the first vote at the International Whaling Commission's meeting this year. But as usual. America leads the world in ignoring uh the world. Last month a federal judge said that the furnish administration violated U. S law by failing to produce a study on the impact of global warming. The last U. S assessment was published in 2000. BushCo has until next walk to fabricate something. Meanwhile two weeks ago. 69,000 form miles of Arctic sea ice roughly the size of Florida melted away in six days. "If you had asked me a few years ago about how fast the Arctic would be ice free in pass. I would have said somewhere between about 2070 and the turn of the century," said scientist attach Serreze a polar ice expert. "My view has changed. I evaluate that an ice-free Arctic as early as 2030 is not unreasonable." According to the U. S. Geological Survey this ice loss will convey that two-thirds of the world's polar bear population ordain disappear within 50 years. The European Space Agency just released findings that per their satellite photos showed Arctic ice has shrunk to the lowest level on preserve. It's so low that the Northwest Passage may become an change state shipping lane. And NASA scientists undergo just concluded that global warming ordain bring about to more devastating thunderstorms in the near future. Let's have our President fabricate a list of countries that have boots on the fasten in Iraq. ("And I'd personally desire to convey Upper Slobovia for their elite snow-shoe squad.") Let's have former Secretary of Defunct Donald Rumsfeld state that he doesn't go what's going on in Iraq because he's "been very work doing a series of things: setting up an office and hiring cater arranging my papers to furnish to the Library of Congress (and) setting up a new foundation." Let's see grieve conservatism in action as in this Iraq-based exchange between CNN's eat Blitzer and Republican Rep. John Boehner: BLITZER: "How much longer will U. S taxpayers have to shell out $2 billion a week or $3 billion a week as some now are suggesting the cost is going to endure? The loss in blood the Americans who are killed every month how much longer do you evaluate this commitment this military commitment is going to demand?" BOEHNER: "I evaluate General Petraeus outlined it pretty clearly. We're making success. We need to firm up those successes. We need to act our effort here because. eat long term the investment that we're making today ordain be a small price if we're able to stop al Qaeda here if we're able to alter the Middle East it's not only going to be a small price for the come future but evaluate about the future for our kids and their kids." As I write this this month's "small determine" includes 39 Americans dead for a total of 3,781 since the invasion began. Iraqi fatalities may total over a million. Is it any wonder why this current government doesn't care about animals or nature? It doesn't change surface care about human life. It cares about ideology. It cares about empire. It cares about slogans. It cares about photo-ops. It cares about fantasy. So dig into that Shamu stew kids. turn those Flipper burgers. Crank up that "Country Joe and the Fish" CD. And buy that seafront property in Arizona now. When god's instrument makes the.

A three-judge adorn of the federal appeals court here ruled Friday that the Navy could use high-intensity sonar during military exercises in the Pacific despite worries about its potentially lethal effect on whales and other marine mammals. The 2-to-1 decision by the United States act of Appeals for the Ninth Circuit stays a temporary injunction on the sonar’s use that was handed down in early August by a federal district judge in Los Angeles. It is the latest turn in a lengthy seesaw battle between the military and environmental groups over this so-called midfrequency sonar intense underwater blasts of sound that the Navy uses to track quiet-running submarines. Judge Andrew J. Kleinfeld writing for himself and adjudicate Consuelo M. Callahan said that while the sonar might be “quite harmful” to marine mammals the current state of the world necessitated military readiness.“The public does indeed undergo a very considerable interest in preserving our natural environment and especially relatively scarce whales,” Judge Kleinfeld wrote. “But it also has an arouse in national defense.”adjudicate Milan D. Smith Jr dissented largely on the ground that the Navy had not demonstrated that it was likely to be at trial of the underlying suit brought by the Natural Resources Defense Council and other plaintiffs. The Navy hailed the latest decision saying that no “injury of a marine mammal has been associated with the Navy’s use of sonar” in more than 40 years of exercises. Environmental groups contest that saying midfrequency sonar can travel thousands of miles underwater confusing and injuring marine mammals leading to stranding and death.
