Biological invasions are complex processes requiring coordinated and spatially targeted management. This study assessed spatiotemporal trajectories determinants of Prosopis cover in Baringo County, Kenya. Land data for every seven years between 1988 2016 revealed the presence Prosopis. We tested trajectory clusters using spatial autocorrelation overlaid categories with landscape features. Gener...

In this paper, a crude methanolic extract from the stem bark of Prosopis cineraria, a plant native of Pakistan, was tested for its possible presence of spasmolytic, bronchodilator, and vasodilator activities in an attempt to validate some of its folkloric uses. Moreover, attempts were made to provide plausible explanations of the observed biological activities. The extract caused relaxation of ...

background lead is a toxic metal with a poor electrical conductivity. this metal can be hazardous and poisonous even in low concentrations. objectives the objective of this study is the evaluation of prosopis mimosaceae sawdust as a low-cost adsorbent for removal of the lead from effluents. materials and methods the experiment was conducted in a batch system and the effect of ph, the amount of ...

Many arid grassland communities are changing from grass dominance to shrub dominance, but the mechanisms involved in this conversion process are not completely understood. Aeolian processes likely contribute to this conversion from grassland to shrubland. The purpose of this research is to provide information regarding how vegetation changes occur in an arid grassland as a result of aeolian sed...

Our objective was to determine if long-term increases in precipitation can maintain grasslands susceptible to desertification, and initiate a reversal of historic regime shifts on desertified shrublands. Perennial grass production and species richness in a multi-year wet period were hypothesized to be greater than expected based on precipitation in a sequence of dry years. These responses were ...

This study aimed to determine phenolic compounds of Artemisia spicigera (family Asteraceae) growing in East-Azarbaijan province of Iran. 20%, 40 % and 60% SPE fractions of methanolic extract of A. spicigera, were subjected to reversed phase preparative HPLC, with the mobile phase consisted of methanol and water. Structural identification of phytochemicals by spectroscopic methods including UV a...
