Effects of the environment on species richness and composition of vascular plants in Manaslu Conservation Area and Sagarmatha region of Nepalese Himalaya / RAI, S.K. in BANKO JANAKARI - वनको जानकारी : A Journal of Forestry Information for Nepal, 26: 1 (2016)

Title : Effects of the environment on species richness and composition of vascular plants in Manaslu Conservation Area and Sagarmatha region of Nepalese Himalaya Material Type: printed text Authors: RAI, S.K., Author ; SHARMA, S., Author ; J. P. Gajurel, Author ; SHRESTHA, K.K., Author ; M. P. Nobis, Author ; C. Scheidegger, Author ; S. Devkota, Author Publication Date: 2016 Article on page: 3-16 p. Languages : English (eng) Keywords: Canonical correspondence analysis, elevation, generalized linearmodel, land use types, multivariate analysis, species richne Abstract: This study analyzed how the environmental conditions constrained the species
richness and composition in the four river valleys of Central Nepal i.e. two from
Manaslu Conservation Area (MCA) and two from Sagarmatha region. Topographical,
bioclimatic and measured variables were used to analyze their effects on the
vascular plant diversity along elevation and land use gradients. Altogether, 148 plots
were established at five elevation levels between 2,200 m and 3,800 m above the
mean sea level. Four land use types namely crop field, meadow, exploited forest
and natural forest were sampled at each elevation level. Altogether, 790 species of
vascular plants belonging to 114 families were recorded; Asteraceae had the highest
number of species (84) followed by Rosaceae (52) and Poaceae (50). Explorative
data analysis of species composition by canonical correspondence analysis (CCA)
showed that the topographical variables explained the composition better than both
the bioclimatic set of variables and the logger data. However, all groups of variables
revealed significant effects on species composition. Generalized Linear Model
(GLM) also revealed significant effects of elevation, land-use types, slope angle,
aspect, temperature and precipitation on species richness.ssLink for e-copy: http://lib.frtc.gov.np/elibrary/?r=573

Title : The frequency and relationship of flowering plants on the distribution pattern of Ophiocordyceps sinensis (Yarchagunbu) in the highlands of Dolpa district, Nepal Material Type: printed text Authors: S. Devkota, Author Publication Date: 2009 Article on page: 29-36 p Languages : English (eng) Keywords: Alpine zone, flora, Ophiocordyceps sinensis, pasture management, Yarsagumba Abstract: Ophiocordyceps sinensis (Berk.) G.H. Sung, J.M. Sung, Hywell-Jones & Spatafora is a highly valuable medicinal fungus. Biologically it is an entomopathogenic, entomophagous or entomophilous fungus. In order to investigate different floral associations with O. sinensis, and to know different threats to pasture biodiversity, research was conducted in three pastures of Raha and Majphal Village Development Committees of Dolpa district. The study revealed that Juncus thomsonii and Bistorta macrophylla were the principal plant associates with O. sinensis as they dominated the alpine pasture vegetation. This research also highlighted the need for some proactive solutions along with conservation awareness program as important management initiatives to ensure ecological balance of O. sinensis.
