Brunnichia ovata (Walter) Shinners is a native, perennial, woody vine with the potential to become an aggressive competitor of the federally endangered shrub Lindera melissifolia (Walt.) Blume. Our study simulated habitat disturbances to hydrologic regime and light availability that may occur...

The indigenous forage species such as Buffel grass (Cenchrus ciliaris) are capable of surviving with less water than most introduced species such as Rhodes grass (Chloris gayana) and alfalfa. However, the productivity of Buffel grass as a function of the amount of water applied is unknown. A case...

Parasitism by the root-parasitic plant, Striga (Striga hermonthica L.), is a main threat to pearl millet production in sub-Saharan Africa and nutrient deficiency aggravates this problem, often leading to complete failure of pearl millet crops. Like many other species, pearl millet secretes...

During 2009-2011, six species of energy grass were introduced to 5 ecological regions of Guangxi Province, i.e., Nanning City, Lingyun County, Tiandeng County, Gongcheng County and Pubei County. The introduced species included Pennisetum purpureum cv. Red and Guimin, [P. purpureum cv. Mott×(...

Increases in the concentration of atmospheric CO₂ and plant invasion are two important problems that face humans worldwide. In some plants, exposure to a short-term elevated concentration of CO₂ (SE [CO₂]) promotes photosynthesis, but the promotion of elevated [CO₂] (E [CO₂]) to photosynthesis...

The knowledge of phenotypic variation in the European range of the highly allergenic Ambrosia artemisiifolia L. (common ragweed) is not entirely complete, even though it is an invasive species of utmost concern. We hypothesized the prevalence of phenotypic differentiations between common ragweed...

Climatic changes can severely impact the biological and physical components of our earth. Invasive species are considered a threat to native species owing to their competitiveness. The changing climate particularly the increasing CO₂ levels in the atmosphere can increase the proliferation of...

Research is needed to look for plants or lines that can thrive on soils affected by water deficit or other constraints. The present work investigated the potentiality of Saccharum spontaneum L. spp. aegyptiacum (Willd.) Hack., a lignocellulosic, perennial, rhizomatous, no-food crop in semi-arid...

Trait differences between invasive and native species are believed to be closely related to whether the former are successful. However, few studies have measured trait differences between invasive and native species directly under field conditions or during long term experiments. We examined the...

Cardoon (Cynara cardunculus) is a herbaceous perennial plant in the vegetable, artichoke, wild or garden, which belongs to the Compositae family (Asteraceae Compositae-and more precisely Cynara species) and is grown specifically for the production of biomass (solid bio fuel as a pellet, or solid...
