When bulls are competing for the same cow, they may use their antlers to fight off their opponents. After the mating season, bulls drop their antlers. They regrow them again in the spring. The young calves stay with their mothers for a year before venturing off to live a solitary lifestyle.
Moose can live more than 20 years in the wild, but many begin to suffer the symptoms of old age before then. A more typical lifespan is 10 to 12 years. Massive and majestic, moose are a cherished wildlife icon of North America. Moose often roam through residential areas looking for food, and motorists occasionally collide with them.
Hunting and habitat degradation are major threats to moose, but now climate change has caused moose populations in Minnesota to fall dramatically. Moose are being hurt by overheating, disease , and tick infestation— all tied to warming temperatures.
Overheating : Heat affects moose directly. These big mammals require cool climates to thrive, and summer heat stress leads to dropping weights, a fall in pregnancy rates, and increased vulnerability to disease. When it gets too warm, moose typically seek shelter rather than foraging for nutritious foods needed to keep them healthy.
Many New Hampshire cows have been under the weight necessary to successfully bear calves the last few years and are producing fewer calves than they did a decade ago. Many biologists are concerned that they will have a difficult time adapting to climatic variability. Too Many Ticks: Warmer winters have also caused spikes in the tick populations, further devastating the moose population. Ticks leave moose weakened from blood loss, and many die of anemia.
Ticks also leave moose more vulnerable to exposure in the winter after their attempt to rub off the ticks leaves them with hairless patches. The New Hampshire moose population has plummeted by more than 40 percent in the last decade from more than 7, moose to just 4, today, and biologists attribute some of this decline to increasing parasite loads influenced by shorter winters caused by climate change.
Wildlife watching and hunting are not just recreational pastimes; they are also a major contributor to the local economy, with wildlife-associated expenditures bringing in hundreds of millions of dollars to states like New Hampshire. In New Hampshire, declining moose numbers have lead to a 80 percent reduction in moose hunting permits, down from in to just in As the moose population drops, the recreational activities and associated revenue surrounding the species is sure to follow.
To ensure the survival of cherished wildlife species like the moose, policies and practices are needed to address climate change.
This includes reducing carbon pollution as well as adopting climate-smart approaches to wildlife conservation. We must make a serious effort to reduce carbon pollution at every level—from the choices we make in our households to the policies we adopt as a nation.
For most people, moose are a pretty foreign concept, but for some, they're part of everyday life. Moose are the largest members of the deer family, weighing as much as pounds; they can grow to be 5 to 6. This does not include a raised head or antlers, so it's safe to say that the majority of moose tower over all non-basketball players.
With huge size comes a huge appetite. Moose are browsers and will casually devour 73 pounds a day in the summer and 34 pounds in the winter. They eat an assortment of shrubs, woody plants, and aquatic vegetation; in the winter, their diet is more restricted, so they eat the buds of plants.
Moose are formidable opponents with sharp hooves that can kick with tremendous force, but even they have predators. A pack of wolves or a black bear is no match for a healthy adult moose, so bears and wolves typically pick off the young, sick, and old. And even though moose are powerful and quite large, a single bite can do one in: There's a good chance the bite will cause an infection that eventually kills the animal up to two weeks later.
Moose also have a much smaller menace to worry about: parasites. Brain worm Parelaphostrongylus tenuis is a parasite contracted from eating snails.
The infectious larvae migrate to the moose's brain and cause neurological damage. Another tiny nuisance is the winter tick. Tick infestations depend on the weather and habitat: Harsh winters mean less ticks the following year; when ticks fall off animals to complete their cycle and there's still snow on the ground, they die. So hard, long winters are great news for moose. When fighting off predators, the antlers, or paddles, don't come into play as much as you would think; a moose's first line of defense is its sharp hooves, which are capable of mortally wounding a wolf or bear.
