The Afrotropic subgenus Deranchylaeus; of the colletid bee genus Hylaeus is revised for the first time on the basis of all the available type material. Here, 28 new synonymies were detected: Prosopis flaviscutum Alfken and Hylaeus graaffi Cockerell = H. curvicarinatus (Cameron); H. microstictus Cockerell = dregei (Strand); H. bequaertianus Bridwell and H. ogilviei Cockerell = H. gabonicus (Vach...

The air dried leaves of Prosopis juliflora Swartz DC., commonly known as Vilayati Kikar was analyzed for chemical composition. The results revealed the quantitative analysis of following classes of natural constituents: flavonoids, alkaloids, saponins, phenols and tannins in the range of (16 ± 0.39), (3.6 ± 0.06), (2.2 ± 0.23), (0.66 ± 0.11) and (0.33 ± 0.07) % respectively. The crude fiber and...

Herbivory by rodents, lagomorphs and insects may locally constrain woody plant seedling establishment and stand development. Recruitment may therefore depend either upon plant tolerance of herbivory, or low herbivore abundance, during seedling establishment. We tested potential herbivory tolerance by quantifying growth, biomass allocation, and survival of defoliated Prosopis glandulosa seedling...

Prosopis chilensis, also named Chilean algarrobo, is a leguminous tree, described as highly tolerant to heat shock, water deficit, salinity and injury stress. The objective of this research was to investigate the germination and growth responses of seeds, seedlings and young plants of P. chilensis under increasing concentrations of N a Cl. Six groups of P. chilensis seeds were germinated. One g...

Seedlings of 2 varieties of honey mesquite (Prosopis glandulosa var. glandulosa and P. glandulosa var. torreyana) were exposed to 2 concentrations of atmospheric carbon dioxide (CO2) (368 and 704 lmol mol ) in environmentally controlled glasshouses under near-optimal temperature and soil water conditions to determine if CO2 enrichment alters aboveand belowground growth responses. CO2 enrichment...

Prosopis denudans, an extreme xerophyte shrub, is consumed by ungulates and threatened by firewood gathering, because it is one of the preferred species used by Mapuche indigenous people of Patagonia. In a scenario of uncontrolled use of vegetation, it is very difficult to develop a conservation plan that jointly protects natural resources and its users. We performed a field experiment to asses...

A phytochemical study of the methanol-soluble fraction of an aqueous extract of a sample of Psittacanthus calyculatus collected from the host plant Prosopsis laevigata (Smooth Mesquite) using several techniques, including co-chromatography coupled with UV detection, chromatographic purifications and IR, NMR and MS studies, resulted in the identification of gallic acid, two flavonol-3-biosides a...

Abstract. Trees of the genus Prosopis from Americas, were introduced in Eastern Africa 1970s to mitigate land degradation and its associated disservices. However, over time these trees have spread invaded valuable grasslands croplands consequently led significant use cover (LULC) changes livelihood stress. Early detection invasive species is essential for formulating effective management strate...
