There is no way that Australia can prevent the extinction of some native animal species. Some can  be preserved with a national gene bank. Though a seed bank has already been set up to save native flora, nothing is planned for fauna. Present debate is centered on the loss of the northern and southern gastric brooding frog. If a gene bank had existed the frog would have been preserved. Australia has the worst record of native animals going extinct than anywhere else, not something to be proud of. Over 40 birds and mammals have disappeared since European settlement. Because government has been slow in allocating resources, private organizations have started gene banks. Indeed Taronga Conservation society Australia has stored genes from 20 native animals. This is far from adequate. Over 2,000 species need preservation. With the Taronga Conservation Society Australia, the Animal Gene Storage and Resource Centre of Australia at Monash University has a total of 100 endangered sp

As meteorologists tell us that natural disasters are becoming regular occurrences due to climate change, so the threat to certain animals species increases. Marine animals are in serious danger. The sea is warming up. It is accepted that whales beaching themselves is "normal". However, dugong doing the same thing is not. CSIRO which is always at the forefront of Australian research says that south-eastern and north-western sea regions around Australia have become significantly warmer. As some species move or even die out and new species arrive the ecological dynamic is disrupted. Death from new diseases becomes the norm. New species eat the food that native creatures eat, so marine animals that have been in the same place for thousands of years are doubly threatened. The future looks bleak. The climate could level off and remain changed but stabilize. On the other hand, change could be ongoing and the variation in marine species could decline. This could affect fo

Endangered species in Australia tend to be those that do not fair well in human affection. Plenty is spent on koalas because they are seen as cuddly. In reality though they are not. Indeed, if one attempts to pick up a wild koala it goes on an all out attack if it cannot get away. Some endangered animals are not exactly ugly. The grey-headed flying fox, a bat, is quite cute as shown in the photo.  It is just not in the mainline thinking of people. The average person knows very little about it. Many cringe when the word "bat" is mentioned. They do carry some diseases, but cases where bats pass these on to humans are quite rare. The grey-headed bat is Australia's largest and is responsible for pollination of many plants, mostly trees. There are more than 19,000 threatened species in Australia, 1,000 of them mammals. Some species that could be saved with a small amount of money are not helped, while others such as koalas get too much money. Koalas are being pampe

Australia's slaughter of wildlife continues despite warnings from CSIRO. Nearly half of Australian mammals will end their existence very soon. Zoologist Fred Ford said 11 extinctions have occurred in recent years in the south-eastern forests of Australia. The reserve system is not working. They are just for show. Plants are doing well because they are surviving outside and inside reserves. Nothing is being done to protect small native mammals. Reserves are havens for introduced feral animals and invasive weeds. Rangers are not being trained to look after the endangered species. Money should be allocated more efficiently. With all the money put into reserves there must be more positive outcomes. Native animal need to be researched and the data must be analyzed. Records should be kept to formulate action. An astounding 65 per cent of reptiles in Australia have been discovered in the last 35 years. The public has not been adequately informed of this. http://www.adventure--australia

Pink dolphins who live off the coast of China are in serious decline. In 2003 there were 158 of them. Now that figure has fallen below 78. The numbers are estimates because they are always on the move. Samuel Hung chairman of the Hong Kong Dolphin Conservation Society says government action is needed to save the species. The dolphins bring tourists to Hong Kong so there is private money that could be used, though major government funding was needed to take effect immediately. Waters near Hong Kong are polluted and young dolphins die from toxins in their mother's milk. It accumulates in seawater. Dolphins right across the world are getting diseases from pollution. Industrial fishing also kills thousands every year. A new species of dolphin has been found off the southern coast of Australia. The Burrunan dolphin ( Tursiops australia ) is in small numbers due to polluted runoff into the sea. The mysterious problem of dolphin beachings continues. Noise of the

Animals are going extinct, though some are still turning up. This is true. In the past 100 years many species have been declared extinct. Oddly, a third of these have been found still living. Many have not been seen for a very long time. This is the reason for them still being around. The okapi a zebra-like animal was recently re-found in the Congo. In Cuba the solenodon "rat" was seen jumping around. Another find was the Indonesian Talaud Flying Fox. In Australia the rock rat was identified. And the Christmas Island shrew came to light. This is embarrassing for the conservationists about to meet in Japan at the United Nations Summit on Biodiversity. It appears that emotion has won out over rationality. It is too easy to make predictions about what will happen in the future. With climate change, little real knowledge is available to researchers, though change is occurring. Perhaps now more cautious steps will be taken. http://www.adventure--australia.blogspot.com/ http

Though there are worries over extinction of all animals, it is reptiles who are in most danger. Some reptiles are pretty, but for the most part they are seen as ugly. Because of this they lose out on conservation funding. This is serious with one in five reptile species predicted to die out. People are moving into previously pristine regions of the tropics to log valuable trees and to practice logging. The conclusion about endangered reptiles has been reached by 200 of the world's scientific experts. Funding is not enough. We need to change human behavior. This of course means changing human needs, which is more challenging. Concentrating on saving turtles is good for them. Other reptiles, however, remain at risk. The living and reproductive systems of many reptiles is still unknown. Out of sight, out of mind leads to extinction. Reptiles tend to live in the toughest of environments. Such specialization does result in their demise when humans change the habitat. Tho

Australia is fighting against the spread of red fire ants. This pest has invaded other countries such as the US. Nothing seems to work to stop their malicious takeover. They give a nasty bite. It was thought to be a simple kind of ant but studies have shown it to be a complex creature. It has two distinct variants in its social structure. Normally colonies keep their distance. On the other hand, many colonies do form a supercolony where queens work together and breed in safety. Ants of the supercolony do kill queens of isolated colonies. The ants are different genetically. Queens of individual colonies are fatter. This is to feed the first larvae when they start the colony. Queens who work together never need the "boost" fat. The change of a single gene dramatically changes physicality and behavior. It is contentious as to whether there will be an evolutionary winner. We just do not know at this stage. It is hoped that chemicals producing violent behavior can

Not much can be done about saving endangered species when the great majority of people "don't give a damn". Like global warming many just do not want to hear the truth. Money is not forthcoming for conservation. Stopping animals from going extinct is only being done on a piecemeal basis. We have to choose what to save. This really means that the blame for the loss of some animals lies solely with Mankind. Just who is to decide the fate of creatures is not yet known. It will have to be bodies that receive funding for such purposes. They are probably doing the selection process as we speak. If what is to be saved and what is to be lost was publicly known there would probably be an outcry - everyone has their favorites. More funding is the answer of course. Whether times be good or bad giving money for conservation has never been popular. Other things seem more important. It is really inevitable that prioritizing what goes extinct will occur. The global warming

Birds are the most diverse creatures on Earth.  Not only have they changed into different species on large continents, they have also adapted specifically to environments on islands. A new classification system is in the form of a circle with increasing diversity as one moves out in time from the center.  different types of birds are correctly located on the figure covering a period of 50 million years. There is not one specific ancestor.  "Base" species take the form  of a circle of time moving out from the center and new kinds of birds branch off directly to the outer edge.  Fast evolving birds are in red; slower ones are drawn in blue. Significantly birds such as woodpeckers often split into new species, while hornbills, for example, did not.  There was more diversification in the Western Hemisphere.  Furthermore, species did not proliferate in the tropics because the climate remained stable there over a long period. http://www.adventure--australia.blogspot.com/ http:/

Why bother to be hygienic. We can feed cattle all sorts of filthy stuff, and when we eat it we still remain fit and healthy. This is the message being sent by the president of company Bioniche. In order to promote his new product the president is making dramatic claims. Cattle can all be vaccinated against e.coli, can eat anything and wander around in rubbish, apparently. Such is Mr Rick Culbert's faith in the success rate of his product. The e.coli "bug" lives in all of us both humans and animals. Only dangerous species make us sick. This vaccine will kill all e.coli in the body. Wait a minute! Don't antibiotics kill useful flora in the gut, so we must not take them regularly? What happens to a cow with no e.coli in its system is unknown. Eating such "clean" meat could be dangerous to our health. Outbreaks of food poisoning occur in every country. The fight for cleanliness in food handling must continue. If beef is guaranteed free of e.coli wo

Something is going on out there. Mysterious deaths of particular species of animals occur regularly. Recently dolphins died in their hundreds while thousands of pelicans died off the coast of Lima, Peru. This was followed by thousands of crustaceans dying. The crustacean affected is red krill. It is known that some species of dolphin eat this food. Pelicans also surface feed for krill.  Why would a food source die after poisoning other animals? These deaths are not being caused directly by humans with perhaps chemicals or pesticides. The reason is the ocean off the coast of Lima is warming up. Krill have been moving closer to the coast to avoid the heat. Environmentalists blame offshore oil exploration. The government says they died of natural causes, but the seemingly static La Niña with cool weather in the western Pacific (oddly currently warm in the east) is not natural. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://

Tyrannosaurus rex did not roam ancient Australia. Perhaps another animal had already filled the niche. A new kind of dinosaur could have been the Australian killer and scavenger. The animal had stubby arms and could not live in central Australia because it was a vast desert. The abelisaurid was a strange looking creature but it was the top killer. They not only dominated Australia. Their presence was felt right across the Southern Hemisphere. Different species of the animal reigned in various regions. The 21 foot long abelisaurid enjoyed a hot climate that changed from very wet to dry. They existed for a long time, right back to Pangea the supercontinent. Like Tyrannosaurus rex they had a vicious bite. Abelesaurids had arms even less useful than Tyrannosaurus rex : abelesaurids had no wrists. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://adven

Glow worms can tell the time. Yes it's true! An Australian researcher has found that glow worms "light up" during daylight hours, even though they are in total darkness 24 hours a day. It is only a Tasmanian species of glow worm, however. Mainland species glow day and night. It is not known how they detect that it is daylight outside the cave. It is thought that a chimney effect occurs in a cave, whereby air is "breathed" in and out from outside. This probably causes a change in temperature. Glow worms possibly use the temperature stimulus to choose when to glow and when not to glow. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://adventure--australia.blogspot.com . . . . . . . . . . . . . . . . . .

scientists have been wrong in the past and in some cases are still wrong today. Things that have been taught as fact for centuries are now found not to be true. Cycads have been called living fossils for a very long time. However, the species that survive today were not around when dinosaurs roamed the planet. Will they find coelacanth fish, horseshoe crabs and gingko trees to also be recent branches on their family trees? Many scientists are still fighting for Pluto to be reinstated as a planet. Now cycads will be struck off the living fossil list. When a new find of an ancient individual related to humans is announced, along with the excitement is the claim that it is the missing link between Man and lesser apes. Common sense would tell us that the missing link will probably never be found. Be prepared for "truths" held for centuries to fall by the wayside. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedb

Predictions on what alien life could look like are limited: movie aliens are typically humanoid with various outer "textures". An understanding of the evolution of life forms on other planets can be gained by examining slimy mold in forests. Amoebas living in slime for the most part are single-celled creatures, but they do collect together forming complex bodies that crawl. Other groups pulsate. New work has identified signals that make the little creatures congregate together. Researchers put Phusarum polycephalum (many-headed slime mold) in a maze, then placed two pieces of food further inside the twisting corridors. The "thing" tested the paths with tendrils, backing away when it reached a dead end. Four hours later it located and devoured the food. A map of Spain was laid out and food was placed on large cities with slime mold being released to do its work. A network of tentacles spread out over the map almost exactly the same as the highway system of Spa

It is amazing that a species of dolphin has been living along the coast of Australia and scientists did not know it - until now. The Burrunan dolphin is the third new species to be identified since the 1800s. Named Tursiops australis , the new mammal is represented by two small groups living among bottle-nosed and common dolphins living off the Victorian coast. They are quite distinct from other dolphins having different body shape, skulls and DNA sequence. The discovery came as quite a shock and shows that new species of other animals could be living unidentified in regions already extensively examined. Man may be going into space but much of our planet still remains unexplored. New species still need to be classified in South America. The behavior of some creatures is not yet fully understood. For example, giant catfish in Asia are suspected of taking people swimming across rivers. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.f

It has recently been discovered that the way to fight the intrusive cane toad in Australia is to fence off all waterholes and dams. Without water they die. Another method has also been identified. A chemical that is in the toad itself is used against it. Tadpoles contain this chemical that kills toad eggs on contact. Those that survive grow at a slower rate than normal, so they are more vulnerable to predators. The chemical is harmless to native species. Ways of implementing this strategy nationwide need to be developed, but this is only a matter of time. The pest has just reached the far west coast of Australia, leaping its way across the whole country. West Australians are on search and destroy missions into the night. Queenslanders gave up on this years ago at it had no impact on their numbers. The fight continues. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.te

Australian moths and butterflies are being barcoded. There are 10,000 species in Australia and 65 per cent of them have been coded, 28,000 specimens in all. They are not flying around with a tag on them. DNA is analyzed then recorded with an image of a specimen in a barcode system. The database is a combined project by the Atlas of Living Australia (ALA) and CSIRO's Australian National Insect Collection (ANIC). It is the first time such a system has been used to categorize a group of insects in a country. This is the beginning. Plans are in train to record most organisms worldwide. The technology has been used to determine if wrongly named fish are being sold. It will be used to identify dangerous pests coming into Australia. Species will now be more effectively categorised in research. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://a

A fly is a fly and a mosquito is a, well, mosquito right? The difference isn't as distinct as that. A CSIRO research team has reached the conclusion that in evolutionary terms they are very close. They are both on the same main evolutionary branch: flies splitting of this line 175 million years ago, mosquitoes 50 million years. Flies make up a tenth of all animal species on Earth. There are 152,000 fly species in total. Flies are very interesting having three evolutionary attempts at flying until evolving with the flying method of today. Earth has had very different climates in the past. Despite dramatic changes flies survived. They can consume any nutrient rich substance available. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/http://adventure--australia.blogspot.com . . . . . . . . . . . . . . . . . .
