Question: 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?

Temperate coniferous forest is a terrestrial biome found in temperate regions of the world with warm summers and cool winters and adequate rainfall to sustain a forest.  In most temperate coniferous forests, evergreen conifers predominate, while some are a mix of conifers and broadleaf evergreen trees and/or broadleaf deciduous trees. Temperate evergreen forests are common in the coastal areas of regions that have mild winters and heavy rainfall, or inland in drier climates or mountain areas.  Temperate coniferous forests are only found in the Northern Hemisphere in North America, Europe, and Asia.  A separate ecoregion, the tropical coniferous forests, occurs in more tropical climates. <SEP> 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. <SEP> Temperate forests correspond to forest concentration formed in the northern and southern hemisphere, or in temperate regions.  It is the same as a tropical forest except for the climate and some of the animals adaptations.  Main characteristics include: wide leaves, large and tall trees, large wild canopy and non seasonal vegetation.  Temperate forests can be further distinguished by weather patterns and geographical features that favor the predominance of certain kinds of trees.  In temperate coniferous forests, evergreen conifers predominate, while in temperate broadleaf and mixed forests, a more even distribution exists between evergreen trees and deciduous trees.  Temperate deciduous forests, a subgroup of temperate broadleaf forests, consist of trees that lose their leaves every year.  Finally, temperate rainforests typically have heavy rainfall and dense humidity.  But in some temperate forests there are just trees with needles and do not shed their leaves during the winter, so the climate is a little different and not as cold.  They are also known as montane forests. <SEP> The moose (North America) or elk (Eurasia), "Alces alces", is the largest extant species in the deer family.  Moose are distinguished by the broad, flat (or "palmate") antlers of the males; other members of the family have antlers with a dendritic ("twig-like") configuration.  Moose have been reintroduced to some of their former habitats.  Currently, most moose are found in Canada, Alaska, New England, Fennoscandia, Baltic States, and Russia.  Their diet consists of both terrestrial and aquatic vegetation.  The most common moose predators are the gray wolf along with bears and humans. Unlike most other deer species, moose are solitary animals and do not form herds.  Although generally slow-moving and sedentary, moose can become aggressive and move quickly if angered or startled.  Moose typically inhabit boreal forests and temperate broadleaf and mixed forests of the Northern Hemisphere in temperate to subarctic climates. Hunting and other human activities have caused a reduction in the size of the moose's range over time.  Their mating season in the autumn features energetic fights between males competing for a female.
