In conservation biology genetic diversity is recognized as an important criterion to consider when prioritizing populations for protection. Today, population genomics offers the opportunity to evaluate both neutral and adaptive components of genetic diversity directly at the genome level with molecular tools. By screening the genome with many genetic markers, it is possible to detect loci suppo...

The paper investigates communities in Nigeria specifica ecosystem with the aim of generating baseline information on the similarity and diversity of emerging plant species. Hence the Jaccard Index of similarity and diversity was used to assess the variable nature of observed post remediation soil recovery sites. The study shows that the comparative analysis using the Jaccard successio 38.08% si...

Gonabad located at Khorasan Razavi and coordinates 580 30’ N 34o 35’ E. The highest point of the zone belongs to Peak of Siah Mountain (height of 2,863 meters above sea level) and the lowest place has height of 810 meters above sea level, which is located in North West in salt desert. The mean temperature of the warmest and coldest of year is 29.3 and 3.9 respectively. Mor...

Diversity indices are frequently applied in the form of ratios of absolute diversity to the maximum diversity possible. Regardless of whether the maximum diversity is defined to be limited by the number of species or by the number of individuals present, the resultant indices can be shown to possess mathematically undesirable qualities. All such indices, including equitability as measured by Pi...

overgrazing, via harvesting of forage species and decrease the other herbs, is of progressive factors in biodiversity destroying. in order to investigate the animal grazing impacts on changing of plant structure and diversity, we selected the comparison between this effect with exclosure area, and proving of the excluded area effects on plant diversity; two sites of kojour rangeland, mazandran ...

The aim of the study was to determine the species richness (S, Chao1 index) and diversity (Shannon–Wiener H’ index, diversity profiles) of small mammal assemblages in woodland reserves in an urban agglomeration and to compare the similarity of assemblages (with the use of Ward’s method) in terms of proportions of small mammals connected to the habitats of different level of naturalness. The wor...
