BRISBANE, Australia, June 2 (UPI) -- The males of two new species of dusky antechinus discovered in Australia spend their annual mating season coupling with as many females as possible and then die within weeks -- yet that isn't what threatens the species' existence.
Researchers who discovered the two new species, one in remote Tasmania and the other in mainland Australia, already have been working to get at least one of them on the threatened species list because climate change, feral pests and development, in addition to their annual suicidal sexcapades, threaten their existence.
