The most important environmental driver is the elevation in mountain ecosystems. It strongly influences the distribution of species richness. Species richness is an indicator of the biological diversity and ecological condition of the area. To understand the status of phytomass, species diversity, and physico-chemical properties of soil along the altitudinal gradient and its influence on […]
In order to compare the effect of sowing date on plant growth, development stages and forage yield of three Astragalus cyclophyllon G. Beek ecotypes, a study was conducted in 2010-2011 cropping years in Hanna station, Semirom county, Iran. Three Astragalus ecotypes were originated from Hanna, Golpayegan and Chadegan in Isfahan province, Iran. Seeds were sown […]
Salinity stress and drought stress are the major environmental constraint for promoting medicinal plants in the arid lands of Morocco. To extendthe cultivation of Thymus satureioides in Tafilalet zone, Morocco, we investigate (in 2020) the effects of salinity and drought stresses on seed germination traits of T. satureioides. Salinity treatments included six concentrations of NaCl […]
Global climate change has been linked to the increase in greenhouse gas (GHG) emissions. Wooded grasslands refer to an understudied landscape contributing an unknown quantity of GHGs to global climate change. The objective of this study was to determine the effects of topography and vegetation cover on carbon dioxide (CO2), methane (CH4) and nitrous oxide […]
Coronilla varia L., crown vetch, has wide adaptation, and desirable morphological characteristics for a grazing plant, tolerates short periods of overgrazing, and accordingly has potential as a forage crop. In this study, 15 traits were investigated to assess the morphological diversity of 52 populations using univariate and multivariate analyses. Crown vetch seeds provided by the […]
This study investigated the effect of grazing on plant community structure. Two adjacent areas: one grazed for five years and non-grazed were sampled in March-April 2020. On each area, three sampling sites were selected. Quadrats of 1×1m were placed at 5m intervals along 50m transects (198~ 40 transects in total). Plants were identified and percentage […]
Rangelands ecosystems play a critical role in regulating the emission and uptake of the most important Greenhouse Gases (GHGs) such as CO2, CH4, and N2O. However, the effects of grazing management on GHG fluxes in the semi-arid lands of East Africa remain unclear. The present study compared the effects of three grazing systems on cumulative […]
This research was conducted in Mustang district to see the effect of plant diversity and soil properties on aboveground biomass in altitudinal gradient. Above ground biomass estimation was done using various mathematical equations. Soil properties determination was done using calorimetric, Kjeldahl Dry-block method, feel method and core sampling methods. Simpson’s Diversity Index and Shannon-Wiener’s diversity […]
Growth season rain pulses affect biological and physiological activities of wild plants in arid and semi-arid regions. Despite of numerous reports on the effects of rain pulses on plant physiological indices, there is little information on how rain pulses may affect secondary metabolites of medicinal plants. Caper (Capparis spinosa L.) plays a critical role on […]
