The objective of this work was to characterize and quantify the genetic variability of 39 barley elite genotypes from a Brazilian working collection belonging to Embrapa, using RAPD (Random Amplified Polymorphic DNA) molecular markers.Genomic DNA samples were extracted from leaves of each genotype and 15 decamer primers were used to obtain RAPD mol
Fire is an important agent of disturbance in tropical savannas, but relatively few studies have analyzed how soil-and-litter dwelling arthropods respond to fire disturbance despite the critical role these organisms play in nutrient cycling and other biogeochemical processes.Following the incursion of a fire into a woodland savanna ecological reserv
Abstract Background House mice (Mus musculus) are commensals of humans and therefore their phylogeography can reflect human colonization and settlement patterns.Previous studies have linked the distribution of house mouse mitochondrial (mt) DNA clades to areas formerly occupied by the Norwegian Vikings in Norway and the British Isles.Norwegian Viki
