species diversity
The world is in the midst of an ecological explosion with devastating implications. Thousands of species of microbes, plants, and animals are being introduced, both deliberately and inadvertently, to new land areas, seas, and freshwaters. In many regions, these new colonists are running wild, disrupting the dynamics of ecosystems, pushing native species toward extinction, and causing billions...
A study was conducted to identify the role of community forests in the conservation of faunal diversity in various community forests practiced in the Satbariya Range Post of Dang district. The study aimed to understand and evaluate the role of community forests in biodiversity, especially faunal conservation efforts. Different methods such as questionnaire survey, group discussion and...
A total of 30 fish species from different sampling stations were recorded. Psilorhynchoides pseudecheneis, endemic fish of Nepal, was recorded from all seven stations, which can be considered as a common species of the study area. Recorded fish species were classified into two orders and five families. Order Cypriniformes comprised of four families: Cyprinidae, Cobitidae,...
Seventy-nine Actinomycetes were isolated from soils of Kalapatthar (5545m), Mount Everest region. Twenty seven (34.18%) of the isolates showed an antibacterial activity against at least one test-bacteria among two Gram positive and nine Gram negative bacteria in primary screening by perpendicular streak method. Thirteen (48.15%) showed antibacterial activity in secondary screening. The...
Visualising the present biodiversity status of Nepal, an integrated approach comprising of biodiversity documentation, bio-prospecting, sustainable utilisation and conservation has become an urgent need. Realising the importance of medicinal plants altogether 45 plants were collected from Khumbu region with the altitudinal variation of 2582m to 4470m. Among the collected plant species 12...
Nepal hosts 16 plant species of CITES appendix. The CITES appendix II includes Cyathea spp. (tree fern, Family Cyatheaceae) and the appendix III includes Cycas pectinata (Family Cycadaceae). During an ecological survey of Churiya hills of eastern Nepal, these two rare and endangered plants have been recorded in their natural habitats. The Churiya in eastern Nepal...
Biodiversity offsets are measurable CONSERVATION OUTCOMES resulting from actions designed to compensate for significant residual adverse biodiversity impacts arising from project development6 after appropriate prevention and MITIGATION measures have been taken. The goal of biodiversity offsets is to achieve NO NET LOSS and preferably a NET GAIN of biodiversity on the ground with respect to...
The present work enumerates a total 26 desmids (Chlorophyta) from ponds and reservoirs in and around Koshi Tappu Wildlife Reserve, Nepal. They belong to 8 genera i.e. Closterium (4), Euastrum (4), Micrasterias (3), Cosmarium (7), Staurastrum (3), Onychonema (2), Hyalotheca (1), and Desmidium (2). Of these, 11 taxa are new...
The present paper deals with 37 taxa, 18 genera, 32 species, 4 varieties and 1 forma explored from southern Himanchal Pradesh of India. These taxa are represented by Microcystis, Chroococcus, Aphanocapsa, Aphanothece, Merismopedia, Coelosphaerium, Gomphosphaeria, Stichosiphon, Oscillatoria, Lyngbya, ...
Conservation and management of rangelands require clear understanding of species composition. The objective of this paper is to show the differences in species composition, abundance, mean cover and height between the grazed and ungrazed plots in a specific pasture of Lo Manthang VDC in Upper Mustang. Two seasons' data were collected during July (wet season) and November (dry season) 2005....
