Description

  1. Scientific and common names
    The scientific name is Alces alces gigas, or Alces americanus, common name, Alaskan moose.

  2. Habitat and geographic range
    Alces americanus gigas mostly resides in North America primary in Alaska, Canada and the northeastern United States (Bord, 2009). Regarding their habitats, Alaskan moose preferer temperate and terrestrial regions that have seasonal snow. This includes terrestrial biomes of the tundra with low vegetation, taiga composed of coniferous and boreal forested, usually an alternation of long winters and short summer at high elevations and mountains. For survival purposes, Alaskan moose will be located near regions of water and appropriate food sources (Bord, 2009).

  3. Size / weight & lifespan
    Alaskan moose, typically have a lifespan between 15 to 20 years old; however, 50% of young calves are unable to survive due to predation risks. In a research paper published in 1978 (Franzmann, 1978) scientists measured the total length and weight of a sample population of Alaskan moose. Researcher classified the data collected by, sex, age, the month of samples, and location. In searching through various primary articles, this was the only scientific paper regarding weight and size in different conditions. Researchers concluded that measurements of total length are better indicators of growth rate than weight, and seasonal weight patterns increase from spring to late fall. The average weight and length for males were between 360kg -600kg and 2.5m to 3.2m, as for females the average weight and length was between 270kg to 400kg and 2.4m to 3.1m (Franzmann, 1978).

  4. Diet
    Alaskan moose are herbivores with strong foraging capabilities, they on average require 20kg of food per day, and their diet selection varies between twigs and stems of woody plants (Bord, 2009). In the experiments by Wam, 2010, researchers examined summer and winter diets in relation with foraging abilities in moose. Scientist conducted fieldwork to retrieve information about moose foraging abilities, they also collected sample numbers of the plants in the respective location. Researchers further completed a series of data analyses to quantify the availability of each plant in the acquired location. The evidence suggests that there was more foraging in winter months compared to summer, and that moose selection varies in plant species. For example, Willows are the most preferred plant when available. (Wam, 2010).

  5. Reproduction and communication
    Alaskan Moose bread between September and October of each year, during this time frame the female estrous cycle lasts approximately 24 days with 15 to 26 hours in heat. The average pregnancy is 231 days, once born calves remain with their mothers for approximately one year, due to that fact that the average number of offspring is one per year. These were the only results found in my literature search, located in the research paper Reproductive Characteristics of Alaskan Moose published in 1993, (Schwartz, 1993). Researcher obtained this information by observing captive and wild moose sexual interactions (Schwartz, 1993). Alaskan moose use vocalizations as communications, both sexes use a load roar to indicate a potential threat. Females use a long moan for when in estrous, this is used to attracts males, while males use a grunt to court a female or engage in male competition. Based on my search of the literature Whittle, C. L, (Whittle, 2000) research paper is the only finding on pheromones being used for communication. In which the researchers collected urine samples from captive moose and conducted a series of chemical analyses to determine the properties of the male urine. The results indicated that male urine released a strong odor that attracts females and the production of male urine is a signal to females of the male moose is in good physical conditions. This is an effective method of communication of both sexes, especially concerning increasing fitness (Whittle, 2000).

  6. Predation
    The major predators to adult Alaskan moose consist of the grey wolf, brown and black bears, coyotes, and humans. The predation risks vary in different seasons, young calves are most vulnerable to attacks by bears during spring and wolf predation is highest in the winter (Bord, 2009). The predation on adult moose by Brown bears was analysed by Dahle et al. Researcher captured moose to equip them with radio collars, necessary for tracking, they monitored the moose with aerial views. Researchers used an observational method of the tracking of the Brown bear, in order not to influence the behaviour, the researchers back-tracked the bear. The scientists recorded 0.8% of mortality rates for females and no observed deaths for males. Thus, they concluded that Brown bears are not an effective predator on adult moose since the mortality rates were so low (Dahle, 2013).

  7. Conservation status
    According to the Internal Union for Conservation of Nature (IUCN) red list, Alaskan moose are of least concern, indicating that there are no immediate threats of endangerment to the species (IUCN, 2018). The majority of the populations expanding, therefore all the common threat has little impact on the population. Intermediate threats are primary humans causing habitat alteration, as well as hunting pressures (Bord, 2009).

  8. Did you know?
    Did you know that a moose can feel at home when they are in the water? They are excellent swimmers, they can swim far distances and go underwater for more than 30 seconds (National Geographic Moose’s, 2018).
