Ecological characteristics of Panicum turgidum in hormozgan province
Panicum turgidum is one of the most important species of Hormozgan coastal rangelands, playing an important role in terms of soil conservation and forage production. This research was conducted in 2011 to investigate the ecological characteristics of Panicum turgidum in Hormozgan. In this research, the distribution map of the species was prepared initially and then […]
Investigation on density, cover and production changes and the effect of soil texture on these factors in sagebrush steppe rangelands of Esfahan province
In order to study the vegetation changes of Esfahan sagebrush rangelands and the role of environmental factors on these changes, four sites located in the steppe region were selected. Alavijeh and Charmshahr had a light soil texture, while the soil texture of Dorr and Baghsorkh was heavy. The quantities of density, canopy cover and plant […]
Morphological, meristic characteristics and mtDNA analysis of Hampala Fish (Hampala macrolepidota Kuhl & Van Hasselt 1823) from ranau lake, Indonesia
Hampala (Hampala macrolepidota) in Ranau Lake is locally known by three size-based names: small size as Kemencut, medium as Arongan and large as Sebarau. To know whether these local names are the same or different species, morphometric measurements, meristic counts and mtDNA analysis were carried out. Five individuals of each size, 157–172 mm total length […]
A review of behavioural ecology and conservation of large predators inhabiting the Central Karakoram National Park (CKNP)
The Central Karakoram National Park (CKNP) stretching across 10,000 km2 of the total 72,496km2 of Gilgit-Baltistan is the largest protected area of Pakistan. Been established in 1993; the national park is yet beyond of catering vital information on ecological features. The park provides sanctuary to the snow leopard Panthera uncia and the grey wolf Canis […]
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. […]
