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?
Moose 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 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. 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. Their mating season in the autumn features energetic fights between males competing for a female.
Leucauge argyra Leucauge argyra is a spider and is known for being the host of the "Hymenoepimecis argyraphaga", a Costa Rican or Puertorican parasitoid wasp. It is found from the United States to Brazil. "Leucauge argyra" (and many other "Leucauge spp.") is known to be a colonial species, with spiders maintaining individual territories/orb webs within a scaffolding of shared support lines maintained by the group. Colonies of multi-generational individuals are often seen with some levels of size stratification (where larger individuals/adults occupy the highest web positions and smaller individuals/juveniles occupy lower web positions).
