Genetic diversity in some euphrates poplar (Populus euphratica O.) ecotypes in Iran using microsatellites (SSRs) markers
Euphrates poplar (Populus euphratica Oliv.) is a unique woody species which is naturally distributed in desert areas of some parts of Asia and Africa. Because of its outstanding features, it is a model plant to study environment stress tolerance. This research was conducted to evaluate the genetic variation in 12 ecotypes of P. euphratica in […]

Diversity and vegetation analysis in Delta Island, Lumbocan, Butuan city, Agusan Del Norte, Philippines
Vegetation analysis is a way to study species composition and structure of a plant community. At the mouth of the Agusan River, two deltas was formed through the accumulation of silt, sand and mud over years. The main island “Isla Noah” is a densely vegetated delta. Four 50 meter transect lines with a width of […]
Allelopathic potential of radish (Raphanus sativus L.) on germination and growth of some crop and weed plants
This study was conducted in the laboratories of Agricultural college, Salahaddin University to investigate the allelopathic potential of Raphanus sativus L. roots aqueous extracts on germination and growth of wheat, and barley crops with three endemic weed plants (Avina fatua , Phalaris minorand, Brassica napus), in order to indicate the potentiality of utilizing this extract […]
Local perceptions of climate change and adaptation strategies in the management of Acacia senegal parks in Niger
Parklands of Acacia senegal play important roles in stabilizing crops production systems and improving the resilience of rural communities in Niger. Population pressure and the effects of climate change strongly impact these parks. It’s in this context that the present study is conducted which aims to analyze the local population perceptions of climate change and […]
Taxonomic cheracterization of some moss families of Mansehra, Pakistan
This paper deals with the taxonomic studies of the representative species of five moss families; Enclyptaceae, Hedwigiaceae, Hypopterygiaceae, Splachnaceae and Timmiaceae reported from Mansehra District-Pakistan. Among these Enclyptaceae and Timmiaceae are acrocarpous while Hedwigiaceae, Hypopterygiaceae and Splachnaceae are Pleurocarpous. The aim of this study was the critical taxonomic characterization of the rare species of the […]
Evaluation of some ecological factors, physiological and morphological traits of Salvia tebesana Bunge
Study on relationships between a species with its surrounding biotic and abiotic environment provides valuable information in terms of optimum choice for utilization, propagation, breeding and domestication. For this purpose several ecological and morphological points of Salvia tebesana was studied in Tabass, where the only habitat of the plant is. It is more important that […]
Effect of anthropisation and revegetation efforts on soil bacterial community structure in Terga sandpit, Algeria
Impact of anthropisation and revegetation on soil microbial diversity was studied by characterizing bacterial community structure in a sandpit located in Terga (Algeria). Soil samples were collected from several sites: an undisturbed forest area with pristine vegetation, a site revegetated by the National Forest Services in 1998, a newly revegetated site by the introduction of […]
Structure and natural dynamics of Dodonaea viscosa communities in Malakand division, Pakistan
The present study aims to investigate the structure and natural dynamics of Dodonaea viscosa in Malakand division. For sampling a 10x10m quadrat was used and 28 stands were sampled. Various phytosociological attributes of the species were calculated. The IVI of 27 plants species was subjected to Cluster Analysis and Ordination which results into the formation […]
Role of Ephemeroptera, Plecoptera and Trichoptera (Insecta) functional feeding groups in leaf decomposition in Tropical River
The riparian vegetation along the riverbanks had an influence on Ephemeroptera, Plecoptera and Trichoptera (EPT) functional feeding groups’ composition (FFG). This is because FFG from these three orders play a major role in leaf decomposition. A study of EPT FFG on leaf breakdown was carried out on two types of leaf packs, single leaf species […]
