Gas turbines provide a means of transferring energy from a pressurized fluid to mechanical energy in the form of a rotating shaft. The gas turbine compresses ambient air in a compressor and then channels the compressed air into a combustion chamber.
The cane toad is an old species. A fossil toad (specimen UCMP 41159) from the La Venta fauna of the late Miocene of Colombia is indistinguishable from modern cane toads from northern South America.he cane toad is native to the Americas, and its range stretches from the Rio Grande Valley in South Texas to the central Amazon and southeastern Peru. This area encompasses both tropical and semiarid environments.

We know that toads poison their predators, but this seems to allow other prey species to bounce back.It is a rare piece of solid evidence for an invasive species causing what is called a âtrophic cascadeâ in the wild, researchers say, where killing off top predators has unexpected effects throughout an ecosystem.he toxic cane toad introduced to Australia in the 1930s is causing ripples through the ecosystem in ways rarely seen when invasive species spread.
