the diversity and richness of species are of important components to evaluate the health of ecologic system of rangelands. this research was conducted to investigate the biodiversity in riparian and neighboring areas via comparison of indices in javaherdeh rangeland of ramsar. plot-transects was randomly used to estimate diversity, richness, dominance, and evenness indices in two regions. multi...
To achieve sustainable development as well as the conservation of natural ecosystems and their biodiversity, it is necessary to study ecological foctors and their impacts on plant species diversity. The Khorramabad-Andimeshk highway was selected in the current study to investigate the diversity of the family Brassicaceae. The length of this highway is 100 km and its height ranged from 420 to 17...
Twenty-nine genotypes of finger millet including six checks namely VL324, VL347, VL348, VL352, VL315 and VL149 were used in the present study for estimating genetic diversity. The revealed highly significant variance all fourteen traits. coefficient varied between 4.62 14.41 per cent. Grain yield plot showed highest GCV (37.33%) PCV (40.02 %) followed by biological (26.21%) (29.75%)...
In order to investigate of genetic diversity in sainfoin based on seed yield and related traits, 36 ecotypes including foreign and Iranian ecotypes, an experiment was conducted using a lattice design with two replications in researches station in Natural Resources and Agricultural Researches Center of East Azerbaijan province. Analysis of variance revealed significant genetic diversity among ec...
Studying genetic diversity is important because a decrease in genetic variability might result in a reduction of the plasticity of the crops to respond to changes in climate, pathogen populations, or agricultural practices. In this study, 72 Sardari wheat (Triticum aestivum L.) ecotypes were analyzed by AFLP markers and 17 phenotypic characters. Three pairs of EcoRI/MseI primer combinations pro...
This study aimed to investigate the effect of canopy trees and shrubs: Pistacia atlantica, Amygdalus scoparia, Amygdalus eburnean on the species diversity and richness of soil seed bank. Ten individuals of each species were selected and one quadrate was established in and outside of crown canopy of each species. In each plot, soil samples were collected from 0-5 and 5-10 cm depths. GLM was appl...

Lonicera macranthoides is an important traditional Chinese herb. The lack of information regarding the genetic structure and genetic relationships among its cultivars has hindered the conservation and utilization of this resource. This study used start codon targeted markers to assess the genetic diversity and other genetic characteristics of five single-variety L. macranthoides populations in ...

a field survey was conducted in wukari, taraba state to assess the diversity and abundance of insect species in selected habitats (residential, open field made up of grassland and an agroecosystem). sampling were done biweekly using light, pitfall and yellow pan traps set in 3 replicates, 30 m apart. insects recovered were wet preserved in 70% ethanol except butterflies and moths. representativ...
