Question
Recently there was a rare discovery with a 72 year old hunter and a White tailed deer in Cleburne County Arkansas. In essay form, what was that amazing find and why is It so tare. What wear some physiological factor that may have a fleeted this rarity? Also compare and contrast this feat with that of Reindeer? Lastly, how many occurrences has this rarity been documented in Arkansas The Shrew is a rather unique mammal that has a rather unique lifestyle. How does Its lifestyle effect its heart and metabolism. What is its heart rate? What does it have to do to maintain this lifestyle? Compare this with that of a humming bird? They have a higher metabolic rate than any other animal. The heart of the masked shrew, heats 800 times a minute, considerably faster than that of the hummingbird. Shrews must eat 80 90% of their own body weight in food daily. Most will starve to death if deprived of food for half a day. I hay eat anything available, but prefer small animals; they are economically important as destroyers of insects and slugs that harm crops. Hummmgb.rds have an optimal fuel use strategy that power s their high energy lifestyle, maximizes fat storage, and minimizes unnecessary weight gain all at the same time Discuss the effects of hibernation on mammalian metabolism and circulation. During hibernation the mammals metabolic rate drops significantly. Metabolism is the body's process of converting food into energy. When the metabolic rate decreases, the body can survive with less food. hibernating animals consume large of food in the months before hibernationExplanation / Answer
1.)
White-tailed deer are the smallest members of the North American deer family. Adult white-tail deer have reddish-brown coats in summer. The color fades to a duller grayish-brown in winter. Male deer, called bucks, are easily distinguished in the summer and fall by their large set of antlers. New antlers are grown annually and fall off in the winter.Whitetail deer are the most nervous and shy of the deer. White-tail deer wave their tails characteristically from side to side when they are startled. They are very agile and may bound at speeds of up to 30 miles per hour through the forest.
White tailed deer are usually born with a number of deformities that make it tough for these rare deer to survive in the wild, and this fawn has several of them, including a malformed spine and legs, a severe overbite, and a mostly white coat.
White-tailed deer live in meadows and forests, and they have poor adaptations for snow, whereas reindeer live in cold areas and have special split hooves for walking on ice and snow. Both male and female reindeer also have antlers. In contrast, only the male of the species for White-tailed deer have antlers.
reindeer have much thicker fur than their white-tailed cousins. This helps reindeer handle the harsh, cold-weather climates they live in. The White-tailed Deer live in areas of Canada and in the United States, including warmer states, such as Louisiana.
The white-tailed deer is the most common type of deer in the United States, and it is also the most iconic, most people recognize it from the movie “Bambi.”
Reindeer have special noses that warm the air they breathe in before it reaches their lungs. This makes it easier for them to breathe air in freezing locations.
Another important difference between deer and reindeer is that the term "deer" refers to a family, where reindeer is a particular species. Although the term “deer” usually refers to common species such as the White-tailed Deer and not reindeer, technically reindeer are a type of deer.
2.)
Animals like shrews have very unique lifestyle and they have very fast metabolisms. Shrews must eat 80-90 % of their own body weight in food daily. Most will starve to death if deprived of food for half a day. They eat anything available, but prefer small animals; they are economically important as destroyers of insects and slugs that harm crops.Shrews are easily startled and will jump, faint, or drop dead at a sudden noise. The Etruscan Shrew (Suncus etruscus) which at about 3.5 cm and 2 g is the smallest living terrestrial mammal.Unlike most mammals, some species of shrew are venomous. Shrew venom is not conducted into the wound by fangs, but by grooves in the teeth. The venom contains various compounds and the contents of the venom glands of the American short-tailed shrew are sufficient to kill 200 mice by intravenous injection.Whereas rodents have gnawing incisors that grow throughout life, the teeth of shrews wear down throughout life.They have a higher metabolic rate than any other animal. The heart of the masked shrew, Sorex cinereus, beats 800 times a minute, considerably faster than that of the hummingbird.
The Etruscan shrew favors warm and damp habitats covered with shrubs, which it uses to hide from predators. Areas where open terrain such as grasslands and scrub meet deciduous forests are usually inhabited. It can be found at sea level but is usually confined to the foothills and lower belts of mountain ranges, though has been found up to 3,000 m (9,800 ft) above sea level. It colonizes riparian thickets along the banks of lakes and rivers, as well as human-cultivated areas (abandoned gardens, orchards, vineyards, olive groves and edges of fields). The shrew, however, avoids intensively cultivated areas, as well as dense forests and sand dunes It is poorly adapted to digging burrows, so arranges its nests in various natural shelters, crevices and others uninhabited burrows. They frequent rocks, boulders, stone walls and ruins, darting quickly in and out between them.
3.) Mammals such as bears, bats, and squirrels hibernate when food becomes scarce. By hibernating, these mammals can survive the food shortage and emerge from their nests when resources are plentiful again. Each animal's hibernation behavior differs, but the effects of hibernation on their metabolism, heart rate and other body processes are similar
Metabolism : During hibernation, the mammal’s metabolic rate drops significantly. Metabolism is the body's process of converting food into energy. When the metabolic rate decreases, the body can survive with less food. Hibernating animals consume large quantities of food in the months before hibernation begins. Because they do not use all of the energy from this food, the extra food is converted into a thick layer of fat. While they hibernate, this fat layer is slowly used up by their body to keep their vital processes functioning.
Circulation : To conserve energy, hibernating animals’ bodies slow down. Respiration rates decline dramatically. Bears normally take 6 to 10 breaths a minute but during hibernation, that drops to less than 2 breaths per minute. Heart rate also drops since blood does is not pumped as rapidly through the body, as less oxygenation and energy need to be delivered to the cells. The Illinois Department of Natural Resources Hibernation Guide says heart rates for the average hibernating animal can drop from 100 to 4 or 5 beats per minute. With bears, the heart rate slows but not as greatly. Bear heart rates drop from around 50 to fewer than 20 beats per minute during hibernation.
