The baseline inventory of the plant biodiversity of central karakorum national park Gilgit-Baltistan (District Hunza Nagar) Pakistan
The baseline study of the flora of Central Karakorum National Park (CKNP) was carried out by field’s trips conduct in the different seasons of the years. The study area was thoroughly surveyed throughout the year to ensure the collection of maximum diversity. The current study focus to the flowering biodiversity exists in the study area. […]
Estimation of genetic diversity among Berberis spp. From Karakoram Mountain Ranges using morpho-pathological and floral characters
The present research describes genetic diversity analyses of medicinally important Berberis species (spp.) from great mountainous altitude i.e. Karakoram Mountain Ranges. High range (0-100%) of Genetic Distance estimates using 31 morphological, pathological and floral characters indicated possibilities of improving the material using genetic selection in Berberis spp. Eleven Berberis accessions were classified in 2 main […]
Evaluation of plant diversity indices and the biomass of Pistacia atlantica under drought stress in grazing and enclosed area (case study: Tag-e Ahmad Shahi, Nehbandan, Iran)
Preparing floristic composition is very important to determine vegetation potential in an area to achieve the best pasture management. In order to plant identification in grazing and enclosed areas (each 4 hectares) 40 plots were established (10*10 m) in Tag-e Ahmad Shahi, Nehbandan. This area has involved in a long period of drought and grazing […]
Biodiversity evaluation of rangelands ecosystems to achieve sustainable development (case study: Dastgerd watersed, Birjand, Iran)
Taken literally, the aim of biodiversity monitoring is to track changes in the biological integrity of ecosystems. Biodiversity monitoring within the rangelands may encompass many aspects and is clearly a very complex task. This study was conducted on rangelands of Dastgerd watershed with the objective of the determining the floristic composition, species diversity, richness and […]
Plant diversity and distribution of weeds in winter season crops of agro-ecosystems in Bilaspur district, Chhattisgarh
A field survey was conducted at five different sites in Bilaspur district Chhattisgarh, during winter season of 2011-12 to identify the diversity and distribution of weed species growing in association with cultured crops and to determine their competitive ability against the infesting weeds. Present study deals with diversity and distribution of weeds in agriculture fields […]
Foraging and pollination activity of Apis mellifera adansonii Latreille (Hymenoptera: Apidae) on flowers of Allium cepa L. (Liliaceae) at Maroua, Cameroon
To evaluate the impact of Apis mellifera adansonii (Hymenoptera: Apoïdae) on fruit and seed of Allium cepa its foraging and pollinating activities were studied in Maroua, from November 2010 to April 2011 and 2012. Treatments included unlimited floral access by all visitors, bagged flowers to avoid all visits and limited visits of A. m. adansonii. […]

The current baseline study of agro-diversity was carried out in the different seasons of the year 2013. The study area was thoroughly surveyed throughout the year to ensure the collection of maximum agro diversity. The current study focus to provide inventory of 74 cultivated flowering plant diversity exists in the study area. For this purpose […]
Morphological variability survey of cyanobacterium Anabaena sp. ISC55 in liquid mixotrophe treatment
The variety of phenotypes of cyanobacteria is accompanied by morphological plasticity changing accordingly to different environmental or culture conditions. In this research, the effect of different treatments of liquid mixotrophe on morphological responses, structural changes and biometrical of Anabaena sp. ISC55 were studied. This investigation was performed in time periods of weekly and daily. Due […]
Diversity and ecological characteristics of family papilionaceae at district nowshera, Khyber Pakhtunkhwa, Pakistan

The members of this family were found in abundance that why infective amount of species were identified, 4 species belong to genus Medicago, 3 species from Vicia, Phaseolus and Lathyrus. 2 species from Trifolium, […]
Effects of planting-hole size, composting animal manure and sack on survival and growth of Eucaliptus camaldulensis, Ziziphus spina- christi and Pistasia atlantica planted in Mehran Plain, Iran
This study tested three methods thought to maintain soil moisture availability and thereby improve the performance of three species (Eucaliptus camaldulensis, Ziziphus spina-christi and Pistasia atlantica) when planted in permanent landscape of Mehran plain: increased planting-hole size, composting animal manure and sack addition. Seedlings of the three species were grown in two planting-hole sizes (30*30*30 […]
