Digitonthophagus gazella (F.) has been widely introduced to the New World and both natural dispersal and intentional releases continue. In this study, we compare a population of D. gazella from South Africa and from the island of Vieques, Puerto Rico, using amplified fragment length polymorphism (AFLP) analysis. Genetic diversity was found to be high in both South Africa (H = 0.3623) and Vieque...

Many studies in the fields of genetic epidemiology and applied population genetics are predicated on, or require, an assessment of the genetic background diversity of the individuals chosen for study. A number of strategies have been developed for assessing genetic background diversity. These strategies typically focus on genotype data collected on the individuals in the study, based on a panel...

Methods We sequenced 867 and 789 nucleotides of cytochrome oxidase I from an average of 19 and 20 individuals for C. meadii and P. smintheus, respectively, from each of the same 18 localities. From the sequence data, we calculated measures of genetic diversity within each population (H, h), genetic divergence among populations (FST), and tested for geographic structure through an analysis of mo...

The genetic diversity and structure of the ant Atta robusta were assessed by ISSR (inter-simple sequence repeats) in 72 colonies collected from 10 localities in the Brazilian states of Espírito Santo (48 colonies) and Rio de Janeiro (24 colonies). The ISSR pattern included 67 bands, 51 of them (76.1%) polymorphic. Analysis of molecular variance (AMOVA) revealed a high level (57.4%) of inter-pop...

to finding out the genetic structure of iranian native horses, as animal blood samples were obtained from diverse areas of iran, in addition, 114 sequences of equine d-loop region were obtained from genbank. total dna of the samples were extracted through salting out procedure and utilized as template for amplification and sequencing of the d-loop region of mtdna. sequence analysis of the 247-b...

Bean leaf beetle, Cerotoma trifurcata (Forster) (Coleoptera: Chrysomelidae), is a common pest of soybean in the Midwest United States. However, there are currently no reports on the genetic variability of C. trifurcata. This study examined 15-30 individuals from 25 sample locations to estimate genetic variability and gene flow within and among C. trifurcata from across the Mid- west. Amplified ...
