What is the most common predator of the animal that is susceptible to the parasite Parelaphostrongylus tenuis and typically inhabit boreal forests and temperate broadleaf and mixed forests of the Northern Hemisphere in temperate to subarctic climates?
Parelaphostrongylus tenuis Parelaphostrongylus tenuis (also known as meningeal worm, brainworm, or moose illness) is a neurotropic nematode parasite common to white-tailed deer, "Odocoileus virginianus", which causes damage to the central nervous system. Moose ("Alces alces"), elk ("Cervus canadensis"), caribou ("Rangifer tarandus"), and mule deer ("Odocoileus hemionus") are also susceptible to the parasite but are aberrant hosts and are infected in neurological instead of meningeal tissue. The frequency of infection in these species increases dramatically when their ranges overlap high densities of white-tailed deer.
Mammals of Australia The mammals of Australia have a rich fossil history, as well as a variety of extant mammalian species, dominated by the marsupials, but also including monotremes and placentals. The marsupials evolved to fill specific ecological niches, and in many cases they are physically similar to the placental mammals in Eurasia and North America that occupy similar niches, a phenomenon known as convergent evolution. For example, the top predator in Australia, the Tasmanian tiger, bore a striking resemblance to canids such as the gray wolf; gliding possums and flying squirrels have similar adaptations enabling their arboreal lifestyle; and the numbat and anteaters are both digging insectivores. Most of Australia's mammals are herbivores.
