Are platypus endangered skin#
All animals leave traces of their DNA behind-in skin cells, hair, feces, or mucus, for example. The innovation of our scientists and partners gives hope for the species. By identifying where this unique mammal still exists, conservation efforts can be focused on these areas. GAPS will allow researchers to comprehensively map the current distribution of platypuses in southeastern Australia. San Diego Zoo Wildlife Alliance collaborates with our partners on the largest survey ever undertaken for platypuses: the Great Australian Platypus Search (GAPS). As climate change devastates Australian freshwater habitat with worrying speed, the platypus is left with nowhere to go. Drought, wildfires, and the resulting soil erosion are also some of the effects of global climate change, destroying water systems that were once considered permanent and causing food shortages for the species. Extreme flooding during breeding season may displace or drown juvenile platypuses in nursery burrows. These tiny, curious creatures are no match for intensified weather events caused by a changing climate. Non-native fish pose another threat: some species compete with platypuses for their favorite invertebrate prey, crawfish, making it more difficult for platypuses to find food. Dams, irrigation projects, and urban water projects directly change the flow of water, often altering the habitat so that it can no longer support a platypus population.
Agriculture, forestry, and urbanization are all claiming former wilderness habitats-in Australia, as in other places around the world. Platypuses are uniquely adapted for their homes, but these spaces are rapidly vanishing as human populations encroach. They navigate deep, murky water and detect the miniscule movements of shellfish and insects with ease. Though bizarre in appearance, platypuses are perfectly designed for their Australian freshwater habitats. With a paddle-shaped tail, sleek fur, webbed feet, and a wide bill, these venomous, egg-laying mammals are truly one-of-a-kind. "Particularly in South Australia, we know the platypus used to extend along the Murray River but are now in some areas practically extinct," Dr Bino said.IUCN Conservation Status: Near Threatened The struggling Murray-Darling River system has already claimed some South Australian platypus populations. The study anticipates platypus will become "locally extinct" in up to 40 per cent of the areas it currently lives. The study found that under current climate change and threat projections, the platypus population could decline by up to 73 per cent over the next 50 years, and their spread shrink by as much as 56 per cent.Įven if threats to the species were limited to current levels, the number of platypus would decline by between 47 per cent to 66 per cent and their population spread shrink by 22 per cent. The platypus was once considered widespread across eastern Australia and Tasmania but its "cryptic" nocturnal nature means knowledge of its population and spread has been limited until now. "We might wake up one day and realise, like the koalas, all of a sudden the platypus is critically endangered," lead researcher Dr Gilad Bino told AAP on Monday.
