One common goal in evolutionary biology is the identification of genes underlying adaptive traits of evolutionary interest. Recently next-generation sequencing techniques have greatly facilitated such evolutionary studies in species otherwise depauperate of genomic resources. Kangaroo rats (Dipodomys sp.) serve as exemplars of adaptation in that they inhabit extremely arid environments, yet req...

Introducción. Los cultivos de cobertura aportan múltiples beneficios al agroecosistema, como lo es la disminución poblaciones nematodos fitoparásitos, debido a su imposibilidad reproducirse en plantas no susceptibles. La selección una adecuada debe considerar ausencia reproducción los nematodos, ya que coberturas moderadamente susceptibles podrían comprometer ciclos cultivo posteriores. Objetiv...

Plant responses to air pollution have been extensively studied in urban environments. Nevertheless, detailed and holistic studies assessing their retaliation contaminants are still limited. The present study evaluates the effect of criteria pollutants (SO2, NO2, PM10 O3) on overall biochemistry resource allocation strategy plants order categorize dominant roadside species (Mangifera indica, Psi...

Unlike distinct species, closely related species offer a great challenge for phylogeny reconstruction and species identification with DNA barcoding due to their often overlapping genetic variation. We tested a sibling species group of pine moth pests in China with a standard cytochrome c oxidase subunit I (COI) gene and two alternative internal transcribed spacer (ITS) genes (ITS1 and ITS2). Fi...

Aim of this study was to determine the Antimicrobial, Cytotoxicity and Antioxidant activities of the stem of Ravenia spectabilis. For this study, the dried stem’s powder of Ravenia spectabilis was subjected to cold extraction with methanol and partitioned with n-hexane, carbon tetrachloride and chloroform. The crude methanolic extracts and its n-hexane, carbon tetrachloride, chloroform soluble ...
