Thus it can be considered that the northern population has more genetic variation than the southern population. Various reasons can be accounted for this genetic variation such as mutation in migration because of changed habitat, inbreeding within the southern population, as well as the genetic mechanisms such as genetic drift and gene flow bringing in forces like founder effect and population bottleneck. Therefore it can be concluded that the highway construction has impacted the genetic variations of the populations of Crotalus atrox.
Crotalus atrox is an eminent species in semiarid communities, deserts of North America and reside in various regions. Although this specific rattlesnake’s species are not regarded as endangered, however, investigating this species will aid in the development of better protection and conservation practices (Brennan, 2008). The heterozygosity of Crotalus atrox, the Western Diamond-backed Rattlesnake’s two populations has been explored in order to ascertain if any change has occurred within the microsatellite diversity amongst the chosen two populations of Crotalus atrox. Investigation of microsatellite diversity leads to better comprehension of genetic fitness and variation within the species. It also provides an opportunity to penetrate on ways of conservation to prevent endangerment caused by the human made (anthropogenic) barriers, which are introduced into the natural habitats.
There have been various studies done to explore the influence of anthropogenic barriers on the lives of various organisms. Landscape genetics reveals the way landscape features may impact the population structure by associating genetic discontinuities with environmental or landscape features. These features include climatic, edaphic, biotic and other ...Download file to see next pagesRead More

On the other hand, yield stress is the point at which a material permanently deforms (Lees, 2011). Stress often causes a material to stretch, which ultimately makes it to strain. In this case, strain it measures the extent a material is stretched.

For the first cycle, the mass of the water alone is the mass of the crucible lid and hydrate, less the mass of the crucible lid and residue after heating. That gives 22.678 – 22.460 = 0.218. The mass of the hydrated salt is the mass of the crucible lid and hydrated salt, less

Since 19th century scientists were aware of some unique identity of an individual which distinguish from others, like finger prints. In 1970, DNA was established as key element in human life and which makes individual as unique creature. Variability in DNA sequences among individual to individual have attracted forensic experts to develop technique based on DNA to identify individual or criminal similar to finger prints.
