Adaptation of the Fennec Fox to the Desert

Adaptation of the Fennec Fox to the DesertHow the fennec pull a fast mavin on (Vulpes zedra) has adapted to the quit surroundThe fennec corn dodger is the cut back(p)est member of the Vulpes genus (formally in the Fennecus genus) only weighing 2.2 3.3 lbs. It is exceedingly distinguishable by its huge ears measuring 6 inches, and a carcass length of up to 16 inches. It is a nocturnal savage that waistband in its burrow and lies for the peltioustest parts of the day (The Nature of Wildworks, 2014.). It is a gameyly social brute and lives in family groups of up to 10 individuals (Fox, 1975). Formerly in the fennecus genus, it was later re-classified into the Vulpes genus which is the main taxonomic group of all foxes. Its geographic range is the north Sahara and Arabian deserts. The fox is under decline cod to being hunted for the fur and pet trade which has had significant impresss on the wild species (The Nature of Wildworks, 2014.) The fennec fox has some adaption s to living in a desert surroundings. These can be broken down into 3 categories Morphological, physiological and Behavioural.MorphologicalMorphological adaptions are changes in the animals organise that helps it adapt to the extreme point conditions of the Saharan dessert. One of the most significant morphologic adaptations that the fennec possesses is its large ears. The ears are used to dissipate erupt and maintain the best ashes temperature of the animal (Wathen, et al., 1971). The ear needs to be large to require a large surface area for heat dissipation. The statement that these truly alter the animal is not entirely unbowed, they do not cool the animal and pocket-sizeer its body temperature, but instead maintain the optimum body temperature. In a study on jack rabbits, the ears were implant to dissipate nearly 100% of all metabolic heat at air temperatures of only 30C (Wathen, et al., 1971). This is only possible if the temperature of the fox is above the enviro nmental temperature. The ears also play a faultfinding aim in nocturnal hunting (Wathen, et al., 1971). The large pinnae of the ear help master take heed number 1 level sound into the ear which gives the fennec acute hearing allowing subscribeional hearing (Ewer, 1973). This is a profound adaption for hunting at night collect to the low light levels, thus giving the fennec the ability to hunt effectively at night using sound as well as excellent night vision.The feet of the fennec are adapted to walking on the hot sand by having hairs covering their fleshy foot pads (Ewer, 1973). This prevents the foot from in reality touching the scolding sand and will prevent injury when the fox is digging its burrow and walking across the hot dessert floor. The strawman paws are specially designed for digging burrows which the fennecs live and breeds in (Ewer, 1973).The fur of the fennec like most dessert animals is vital to coping with desert life. non only does this insulate the anim al, but studies have shown that the light fur of the animal can also consider the solar radiation, then lessening the impact and reducing the heat load on the animal (Dawson Brown, 1970). This is most true in the fennec fox referable to its sandy coloured or sometimes white fur. Mean firearm the thickness of the fur is a protection from the solar radiation of the skin. By creating this barrier, the fur prevents any damage to the skin from direct solar radiation. This is because the fur, as said before, partially reflects the solar radiation while the thicker deeper fur absorbs the heat (Dawson Brown, 1970). The heat absorption also helps the fox stand the freezing dessert nights while it feeds, by preventing the fennecs core body temperature from dropping too low.PhysiologicalPhysiological adaptions are changes in the animals system processes to enable them to adapt to changes in the environment. These changes enable the fennec to adapt to the extreme environment of the North African deserts. Carnivores, just as the fennec, are give in a number of deserts around the world. A study challenge that these organisms face is the replenishment of water system. The fennec gains its water requirements just from having mostly a carnivorous diet. The fennec, by eating alone, can maintain its water ease for over 100 days without having to drink (Vaughn, et al., 2000). This is done by the fennec having rattling concent prised urine that uses the least amount of water possible to function. This conserve a vast amount of water and coupled with its very low evaporate loss. Therefore it rivals small desert rodents in its water preservation (Vaughn, et al., 2000). This relates to selective predation and an ability to feed on a enormous compartmentalization of food stuffs, while being able to become more economical with its metabolic water.The adaption of having a low basal metabolic rate is crucial to survival in dessert conditions. The fennec is no exception to this it has one of the lowest BMRs of all Vulpes species of 60.7 percent (Golightly Ohmart, 1983). This means at rest the fox only uses the minimal amount of water needed to live. This adaption allows a minimalized endogenous heat load which conserves metabolic water. This saving of water becomes critical in the desert due to the low precipitation levels and thitherfore having the adaptation of a low BMR helps maintain any dietary water acquired and conserves it.BehaviouralBehavioural adaptations are changes in the animals transmit help it survive in a certain environment. Previously, little was know about the fennec foxes diet. It was previously thought that they were primarily insectivores and had barely any variety in their diet. However, a new study has shown that they are actually timeserving feeders with food items being mostly insects, but it also feeds on small mammals and even plant material (Brahmi, et al., 2012). The study also shows that locality and teemingness of food can also change the feeding behaviour of the fennec. This adaption is critical to the survival of any dessert animals. The ability to feed on more different food sources opens up many more niches and availability for the animal to survive and feed (Brahmi, et al., 2012).Panting is an adaption that requires short shallow respiration and is solely used in heat dissipation. Panting makes use of evaporative temperature reduction of the mouth, lung and nasal mucosa. This is a very effective way of cooling down without having to sweat. This main advantage over sweating is that in sweating there is salt loss, while in panting there is not (Vaughn, et al., 2000). This is key to the survival of the fennec because of the shortage of food therefore the fennec cannot regain the salt quick than the animal uses up. If the fennec sweated this could become a huge paradox, so it has overcome this problem by making use of the more efficient panting for heat dissipation (Vaughn, et al., 2000). Fennec fox families live and thrive in burrows these help weaken the daily effects of high temperature and low humidity of the desert days. They try shelter from sun exposure and the highest temperatures of the dessert day. A study in tortoises shows that burrows provide a great place to refuge in a desert environment. The study showed that the burrow at 1000 -1200 hrs had much higher(prenominal) humidity and lower temperature than the external environment (Bulova, 2002). This lowers the total evaporate water loss which helps the animal, in this case the fennec, conserve metabolic water, which is key to desert survival. Fennecs therefore make use of the much more stable and milder environment inside the burrow. This helps shelter the fennec from extreme conditions and helps conserve water. This is due to the soil temperature maintaining perceptual constancy no matter what the conditions are outside. The burrow controls the internal environment due to the thermal insulating proper ties of the soil (Reichman Smith, 1990). Therefore the burrow is cooler during the day and bullet during the freezing desert nights.ConclusionTo conclude there are many adaptations the fennec has may that be morphological, physiological and behavioural. The adaptations are a necessity to survive in such an extreme climate, such as the dessert with high heat loads during the day, freezing temperatures in the night, food and water sources are scarce. The adaptions that the fennec utilises all boil down to protection from the incredible temperature change in the dessert, by having large ears to dissipate heat and fur that can reflect but also absorb the heat. This gives protection from solar radiation during the day, and insulating material during the night. The other main reason for having many complex adaptations is to conserve water. The fennecs metabolic water level is maintained by having a low BMR which uses less water in metabolic activity at rest, and also the concentrated u rine which reduces the loss of water via waste. In my mind the fennec fox is perfectly adapted to cope with the extremes of desert life, by imperative its water conservation and body temperature.Word count 1,508ReferencesBrahmi, K. et al., 2012.
