Landscape rehabilitation following mining is required to be resilient disturbance impacts such as fire, drought and disease. As companies undergo the process of certification mine closure, there are notable knowledge gaps on ecological risks associated with mature rehabilitated landscapes, based largely assumption that analogous reference communities. However, response fire across a range lands...
Producers have the possibility to combat human-induced dryland salinity by planting salt-tolerant plants such as saltbush. Saltbush has the potential to be used as a source of food for livestock at a time and place where pasture is not viable. However, saltbush contains high concentrations of sodium chloride salt and some other anti-nutritional factors that have the potential to affect feed and...
Esparcet is not inferior to alfalfa in terms of fodder mass productivity, its nutritional value, content protein and other nutrients. The main tasks creating varieties sainfoin are the selection new, with high productivity green seeds, ecologically adapted, a sufficiently plasticity wide variation environmental conditions cultivation zones, varieties. purpose research assess plasticity, stabili...
Mineral composition of dry Tamarindus indica LINN pulp and seeds was evaluated on samples collected from three different agro-ecological zones of Uganda (Lake Victoria Crescent, and Eastern and West Nile). The objective of the study was to evaluate the mineral composition of T. indica pulp and seed samples from across Uganda's different agro-ecological zones and land use types. Separately groun...
Plant can alter reproductive strategies for adaptation to different environments. However, alterations in flowering strategies and sexual allocation for the same species growing in different environments still remain unclear. We examined the sexual reproduction parameters of Caragana stenophylla across four climatic zones from semi-arid, arid, very arid, to intensively arid zones in the Inner M...
conservation and restoration of biodiversity is very important for degraded rangeland ecosystems. it is necessary to assess the potential of soil seed bank as a major source of species. in this study, the soil seed bank size and composition were compared between exclosure and grazed areas. this was done in chahar-bagh rangelands in golestan province. soil was sampled in exclosure and grazing fr...
Shrubs of the Great Basin desert in Utah are subjected to a prolonged summer drought. One potential consequence of drought is a reduced water transport capability of the xylem. This is due to drought-induced cavitation. We used the centrifuge method to measure the vulnerability of root and stem xylem to cavitation in six native shrub species. The shrubs fall into three categories with regards t...
