The great auk was gobbled up by sailors. Now the importance of such species is highlighted in a study proving how the barren wastes are transformed into a green land where Inuits and Vikings found a haven.
Tiger, leopard and dhole! Carnivores, large and small, govern resources across the whole spectrum of natural habitats, whether terrestrial or marine. Here they interact to give real meaning to the word ecology. Camera traps are proving invaluable for relieving our ignorance of all communities of animals and plants, whether threatened like these, or simply our local wood. We love the tiger, Panthera tigris, the leopard, Panthera pardus and the dhole, Cuon alpinus, (http://www.earthtimes.org/conservation/dhole-cuon-alpinus/2076/ ) and you can read that from our frequent stories on them! Here we study them as an unusual grouping, now called a carnivore guild.
Have we got the answer to urban living when we solve the huge losses of hedgehogs in suburban neighbourhoods? The adoption of wild roofs and city ecoscapes in general brings some species to the new city. We have forgotten some animals that might just help clear the pests from our gardens or maintain plants and birdlife in some ways that we have found impossible. Natural habitat has been replaced largely with novel human solutions that need time to prove themselves. Emotionally, many would give the hedgehog their garden-vote, but the population has decreased so much, it could be too late to bring them back.
When dolphins are 'rescued' in various countries, the car given seems to be ill-considered. We are simply looking at the success rate which is reported to be low, in most places. They could even end up in commercial aquarium shows, but they certainly rarely make it back to the sea.
