The Alaska subspecies of moose (Alces alces gigas) is the largest in the world; adult males weigh 1,200 to 1,600 pounds (542–725 kg), and adult females weigh 800 to 1,300 pounds (364–591 kg) [43] Alaska's substantial moose population is controlled by predators such as bears and wolves, which prey mainly on vulnerable calves, as well as by ...
When the moose population grows too high, the balsam fir population crashes, leading to a crash in the moose population, in a continuing population "see-saw". [19] Moose mostly die from the consequences of malnutrition: they become emaciated and slowed down by arthritis, until they are easy prey for a wolf pack. Also, calves suffer from ...

Western moose eat terrestrial vegetation such as forbs and shoots from willow and birch trees and aquatic plants, including lilies and pondweed. Western moose can consume up to 9,770 calories a day, about 32 kilograms (71 lb). The Western moose, like other species, lacks upper front teeth but instead has eight sharp incisors on its lower jaw ...
Data collected over 19 years at Michigan’s Isle Royale National Park shows moose have more ticks during winters following particularly warm summers, according to a study published in the peer ...
Alaska moose are sexually dimorphic with males being 40% heavier than females. [5] Male Alaska moose can stand over 2.1 m (6.9 ft) at the shoulder, and weigh over 635 kg (1,400 lb). When Alaska moose are born, they weigh on average about 28 pounds, but by five months old they can weigh up to 280 pounds. [4]
The moose calf crop has been declining since the fires of 1988. During that summer there was also high predation of moose by grizzly bears in small patches of surviving timber. The winter following the fires many old moose died, probably as a combined result of the loss of good moose forage and a harsh winter.
The greatest losses of pumas occur from predator control and sport hunting and accidents such as falls and automobile strikes. Poultry, goats, sheep, horses, dogs, cats and calves are potential ...
