of their natural distributions in southern Alberta, Canada. In this semi-arid area, poplars are obligate riparian species but they occupy several intergrading ecoregions. Populus deltoides Bartr. ex Marsh predominates in the warmest and driest eastern prairie ecoregions; P. balsamifera L. occupies the cooler and wetter western parkland and montane ecoregions; and P. angustifolia James and hybri...

Globally, grassland biomes form one of the largest terrestrial covers and present critical social–ecological benefits. In Kenya, Arid Semi-arid Lands (ASAL) occupy 80% landscape are for livelihoods millions pastoralists. However, they have been invaded by Invasive Plant Species (IPS) thereby compromising their ecosystem functionality. Opuntia stricta, a well-known IPS, has ASAL in Kenya poses t...

The increase in water demand regions with limited good-quality resources makes it necessary to study the effect of low-quality on plant metabolism. Therefore, objective this was evaluate and salt stress levels mineral elements accumulation toxic Na+ Cl− leaves their consequences production variables sorghum cultivar IPA SF-15. design adopted randomized blocks a factorial scheme (4 × 4), four co...

Abstract The primary objective of this study was to calculate and assess the irrigation water quality index. Furthermore, an effective method for predicting IWQI using artificial neural network (ANN) multiple linear regression (MLR) models proposed. accuracy performance each model evaluated at end paper. According calculated index based on 49 groundwater samples, Sidi El Hani aquifer good suffi...
