The crowd wave at sporting events in not an entirely human thing. Prairie dogs do the "jump-yip". This keeps others involved and tells an individual how alert others are. It begins like the human wave. One or two will start doing it and at first it is ignored. Then it takes on a mind of its own and soon all are doing it. The wave is just as noisy as the human wave with loud yips coming from everywhere. Prairie dogs use their whole body to make the sound. They raise there front legs then lower them with a "wee-oo" call in sequence. Like humans prairie dogs live in towns. It was believed to be a warning call of the presence of predators, but prairie dogs continue the wave whether a predator is there or not. It is a social activity to test the alertness of others. If fellow animals do not respond a prairie dogs will not forage very much. On the other hand, if everyone is at it, they assume they can eat in safety. Somehow they are making a judgement about

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

Why do Whales beach themselves? The theory is that some coastal regions are shallow so sonar does not bounce back to the animals to tell them to keep away. This is only a theory. There seems to be no way of stopping the mammals from laying themselves on the sand to die a painful death. Dragging them out to sea is an attempt to save them, but they continue toward the beach again within hours. A few days ago killer whales beached themselves on sandbars near Fraser Island. Three of them died. Fishermen have been told to keep their boats well away from the animals. They are trying to find deeper water. The hope is that open sea will attract them and they will move away from the shallow sand. Apparently when a whale beaches, the whole pod panics. The presence of boats, particularly motorized ones, stresses them more. One would have thought that evolution would have "bred" out the beaching trait. The numbers who die each year on beaches is obviously not high enough to

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

Bushmeat is not just a problem in Africa. Asian countries have the same problem, as the demand for meat from wild animals increases. Taking animals from tropical forest changes the whole ecosystem. It is common sense really. As the number of creatures feeding on vegetation and other animals decline there is an abundance of vegetation growth and remaining fauna.  More growth kills off food for these animals. While some plants increase, others decline.  Even the amount of vegetation not consumed can fall.  Uneaten vegetation crowds out growth for all, so saplings do not grow tall. Plants need animals to disperse seeds. Consequently, the variety of plants falls. Just two decades ago the Lambir Hills National Park in Sarawak was pristine. There was an abundance of animals and trees. Now all the large animals have been killed off by hunters after a profit. Once such dramatic change occurs there is no way back. The large animals will not breed back to original numbers. The damage

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

Many animals do better when they live alongside humans. One seldom thinks of spiders though. If you travel overseas you soon discover the huge spiders in rented accommodation. Research has shown that these frightening but usually friendly creatures do grow larger in warm homes. They don't have to be living inside the houses either. Just staying close to warm building is sufficient. The golden orb spider was placed in particular external environment and data were collected. Those near buildings were larger and fatter than their bush cousins. Living in the middle of a car park with the heat given off by cars made them bigger as well. Though many people fear them, urban spiders are harmless. They keep pest insects in check. If they weren't there, we would probably be "eaten alive" by flies and gnats. Rather than spraying and crushing them, put them outside and send them on their way. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspo

During the Middle-Late Pleistocene, one million to 10,000 years ago, more than 50 species of animal disappeared, the last to do so 46.4 thousand years from the present. The reason for the demise of the giant creatures is hotly debated. Some scientists claim that the spread of Man across the globe was the cause. This is suspect, however, because there were so few of them. Killing the odd animal would not have made a significant impact. Many believe that the end date for megafauna is incorrect. As stated above, the theory that humans killed them off by definition means that people and animals lived side-by-side for a considerable time. Evidence in Australia certainly points to this - 13 species of large animals were here on human arrival. Moreover, the people mainly relied on subsistence strategies for food. Their weapons were not very efficient. A boomerang is highly inaccurate and the range of a spear is limited. Megafauna died out over a long period of time, not all at a s

Sheep are not entirely "group" animals. They can be selfish. Each sheep seeks to get to the middle of the pack. The center of the flock is safest from predators. Individual sheep do not care about those on the outside being taken by wolves, for example. Flock behavior has been analysed. The group moves forward as individuals move away from the sheepdog to the center of the group. Flocks are not homogeneous. Sheep continue to struggle to get to the center as the flock as a whole moves. It is now believed that many wild group animals behave in this way. Wildebeests moving away from lions probably act in a similar manner. Pigeons, crabs and seals have been observed acting selfishly. Now the theory is proved. GPS tracking devices were attached to 46 sheep. Then an Australian Kelpie sheep dog took control of the flock. By monitoring sheep movement every second, the belief became solid fact. Sheep either move in a line from the sheep dog to the center of the flock, sca

Alien predators are the main danger to the survival of Australia's native wildlife. Foxes and cats are clearing many areas of native animals. Indeed, Australian fauna has been the hardest hit in the world. Bettongs (rat-kangaroo) and wombats for example are oblivious to the danger when a cat or fox is present. Australian prey have developed camouflage to defend themselves from native predators, but alien predators can see through this. Thousands of years of isolation have made native fauna vulnerable. Other continents have long had the cat, goat, grey squirrel, mouse, pig, rabbit, red deer, red fox and ship rat, so their native animals have learned to survive and avoid extinction.  Responsibility lies clearly with early European immigrants.  The damage was done a few hundred years ago. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://adventure--aust

The argument continues over whether humans were responsible for the extinction of megafauna. Giant emus, large kangaroos, marsupial lions and diprodons were destroyed by Aboriginals in Australia according to new research. This claim is based on fungi in dung of herbivores. For 130,00 years, despite dry periods, charcoal and pollen levels in dung remained the same until Aboriginals arrived. This means that climate change was not responsible for the extinction of megafauna 40,000 years ago. There is a problem with this. When Captain Cook arrived in Australia the Aboriginal population was extremely low. Forty thousand years ago there would have been only a few hundred thousand of them. How could this low number possibly destroy all of the large animals? Some megafauna would have survived in regions where Aboriginals did not go. Australia is a very large continent. It is claimed that when the megafauna died out the vegetation changed with more fires, and eucalyptus forests spr

Knowledge about ancient animals is going in leaps and bounds. Every month or so something new is discovered. Tyrannosaurus rex , for example, had a bite far stronger than imagined previously. The "Terminator" pig-like Archaeotherium was assumed to have the strongest bite of all. This view has now changed. Tyrannosaurus rex was no wimp. It could take chunks of meat out of living victims. In-depth research was done on the head of the ancient beast. A computer simulation with skeleton and muscles showed a tremendous bite of 1350 kilograms of force. This was at the back of the mouth where the bite was strongest. To put this into perspective, modern crocodiles and alligators have a bite of about 1,200 kilogram. The shark is feared, but it has a bite of only 300 kilograms. Dinosaurs were really frightening animals when all animals were very large. Man would have been out of place in such an environment. With animals having tremendous biting power humans would not ha

Hunting animals don't just eat what they "bump into". They select "who" they need to eat to maintain a healthy diet. This gives them a better chance of growing strong and big so they can reproduce and pass on their genes. A team from the University of Sydney, Oxford University, Aarhus University (Denmark) and Exeter University researched the ground beetle (Anchomenus dorsalis). Beetles were divided into three groups: one had a selection of bugs offered to them; the second group had high-protein food; and the third had high-fat offerings. The latter two groups did not fair very well. Those in the first group did very well. They chose ants, slugs, moths, aphids and beetle larvae as they wanted and produced more eggs than the other two. It was known that herbivore and omnivore insects ate varied diets. This study confirms the view that all animals select their food due to inner craving created by the body based on the body's immediate needs. The pr

A study on lungfish, bony fish and cartilaginous fish has a great deal to offer in understanding development of legs for life on land. Lungfish are ancient ancestors of tetrapods - four legged animals. Walking on their fins and breathing air, lungfish bravely moved onto the land. Research has relied on bones preserved as fossils, but muscles cannot be "saved" in this way. A fetus shows ancient stages in a creatures development. This is why a human fetus seems to be reptile-like in its early stages. Examining muscle development of modern lungfish is very informative. Tests were also done on cartilaginous fish such as sharks and ordinary fish. Embryos of cartilaginous and bony fish were genetically altered to promote growth of precursor pelvic fins that in lungfish became legs. Engineered cells were made to emit red and green light. The study on muscles highlighted the fact that bony fish evolved legs while cartilaginous fish did not. Pelvic muscles of bony fish are a
