Man is not the only animal to dominate the Earth. Pheidole ants have spread over all the livable continents. They are so common that a walk in a tropical forest means some are killed by just stepping forward. There are 1,200 species of the genus Pheidole . Each has developed to exist in a particular niche of the ecosystem. In a study of 300 species it has been found that certain species evolved similar characteristics independently. Species proliferated dramatically - from one to 600 species in the Americas. The evolutionary goal was to dominate all niches, first in the New World then in the Old. Expansion across one was independent of the other. Evolution took its own course. Ants are essential for healthy ecosystems. They aerate the soil, disperse seeds and help move nutrients. In biomass they equate with all vertebrates. Their study is indeed important ✴ Biology by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia...

Something has been living out there without our knowledge. Yes, it could be called a monster - a very small one. It is in fact a new species of lizard. A team of scientists from the University of Adelaide has discovered a new kind of Varanus lizard. It was found living in a remote part of the Dampier Peninsula in Western Australia. Consequently, it has named the Dampier Peninsula goanna ( Varanus sparnus ). There are now a total of 77 species of the "genus Varanus ". Sparnus is the smallest found so far. The lizard burrows under the ground beneath hard surface objects like stone and wood. Not much is known about its living habits because it moves very fast. The new species seems to be localized, existing only on the Dampier Peninsula. There are no doubt more currently unknown animals in the region. ✴ Biology by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.co...

There are many species of dolphin. To most people they look much alike. We know that they are very intelligent and like to be in the presence of Man, even if it is only following boats A new species has been identified off northern Australia. It could have always been there or moved there from somewhere else. They are in the "hump" class, having a raised portion below the dorsal fin. Scientists are treating the dolphin as a new species which makes three species of Indo-Pacific humpback. There are four kinds of humpback in total including the eastern Atlantic type, Sousa teuszi l.   Apparently, naming of the "new" species is a complex process based on the previously used naming practice, behavior of the animal itself and its habitat. Discovery of the northern Australian dolphin came about by the first intense study into the humpback genus. It involved examination of 180 skulls and 235 tissue samples. http://www.adventure--australia.blogspot....
