Invasive species have been the focus of ecologists due to their undesired impacts on environment. The extent and rapid increase in invasive plant is recognized as a natural cause global-biodiversity loss degrading ecosystem services. Biological invasions can affect ecosystems across wide spectrum bioclimatic conditions. Understanding impact climate change invasion crucial for sustainable biodiv...

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...

Prescribed burning is a commonly advocated and historical practice for control of woody species encroachment into grasslands on all continents. However, desert grasslands of the southwestern United States often lack needed herbaceous fuel loads for effective prescriptions, dominant perennial graminoids may have poor fire tolerance, and some systems contain fire-tolerant invasive species. We exa...

This study was conducted with the objective of evaluating the effect of concentrate supplementation, formulated with different ingredients (Mesquite pod meal, sorghum meal or wheat meal and mineral supplementation) on performance, intake and digestibility of nutrients in Santa Inês lambs grazing on urochloa grass during the dry season. Twentyfour uncastrated weaned Santa Inês sheep, with averag...

The antitumor activity of ethanol extract of Prosopis glandulosa Torr. (EPG) was evaluated against Ehrlich ascites carcinoma (EAC) tumor model in Swiss albino mice on dose dependent manner. The activity was assessed using survival time, average increase in body weight, hematological parameters and solid tumor volume. Oral administration of EPG at the dose of 100, 200 and 400 mg/Kg, significantl...

The widespread encroachment of woody plants throughout the semi-arid grasslands in North America has largely resulted from overgrazing by domestic livestock, fire suppression, and loss of native large and small mammalian herbivores. Burrowing-herbivorous mammals, such as prairie dogs (Cynomys spp.), help control shrub encroachment through clipping of shrubs and consumption of their seedlings, b...
