Translocation of over-Breeding Species
Trans hole is the regularity to alleviate the over-breeding problem of animal besides killing them. The International inwardness for Conservation of Nature (IUCN) b pathly defines translocation as the delibe sum up and mediated app atomic number 18nt movement of wild individuals from one part of their range to another (e. g. IUCN, 1987). Translocation includes Capture and intervention, captivity or some form of prolonged restraint, transport, print into an unfamiliar location four processes. Despite its wide use and importance, translocation traditionally has a kickoff rate of success due to the effect of chronic stress.But Tufts University has done the notice on translocation and found break through the solutions (Biological Conservation Molly J. Dickens 2010). Administering anesthesia or tranquilizing during capture, reduce the risk of the animal perceive intervention and transport. Normally, Health assays, veterinary visits, or other forms of observation and intervention argon conducted during captivity, descend the total number of visits, thus decreasing added exposure to handling stress.Specific aspects of transport such as vehicle design, stacking density, ventilation, and even the quality of the road and the standard of driving should be measured before translocation. Finally, the use of a soft-release strategy, in which animals adjust to the area in a special designed cage before being released, may decrease novelty of the release site since animals will earn time to adjust to their new environment without additional stress of finding resources or facing predation. This research makes translocation be a feasible method nowadays.There are two types of strategy in translocation. Introduce to a place with similar biotic and abiotic factors but the world of over-breeding species should be small. For the advantage, animals easily adapt the new condition. But the animals still have a high breeding rate, the over-breeding problem will threaten th e ecosystem once again after a long period. Another strategy is to introduce to a place with new environment. It actually passel reduce the breeding rate effectively. But there is a lot of works should be carried out both before and after.Before animals can be introduced into an environment biologists must specialize the reason for the over-breeding and over-population problems and also assess the risk of translocation. After translocation, biologists should study the animals to discipline they are surviving and breeding in their new environment. Translocation is the most fitted for some species of animals. For example, Grey kangaroos are one of the over breeding animals. They are capable of breeding throughout the year, but most breeding occurs in summer. The female kangaroo is usually permanently pregnant, except on the day she gives birth.This leads a high birth rate. Apart from human, the effect of predatory animal on kangaroos population is limit. And also, eastern Grey K angaroos are the most social of the kangaroos and so it is rare to see one alone. One good reason to reach together in a group is that more individuals can be more attentive to possible threats from predators. As kangaroos dead from the effect of predator is low, but the high breeding rate continuously increase the population, ultimately cause over-population. But the grey kangaroos are a high adaptability species.They can still alive in the change of environment and this minimizes the effect of translocation. During a dry period, males will not produce sperm. It is suitable to relocate them to a less wet place to reduce their ability of reproduction. Kangaroos are animals that dont bubble methane. In Australia, kangaroo compete with cattle and sheep. The increase in number of kangaroos enables decrease number of sheep and cattle, and therefore reduces the release of greenhouse gases. This is the main reason wherefore we save the kangaroos rather than eating them.
