Recent research on environmental DNA (eDNA), genetic material shed by organisms into their environment that can be used for sensitive and species-specific detection, has focused the ability to collect airborne eDNA released plants carried wind use in terrestrial plant populations, including detection of invasive endangered species. Another possible application is detect changes communities resp...

Biochar may improve soil hydrology by altering soil porosity, density, hydraulic conductivity, and water-holding capacity. These properties are associated with the grain size distributions of both soil and biochar, and therefore may change as biochar weathers. Here we report how freeze-thaw (F-T) cycling impacts the grain size of pine, mesquite, miscanthus, and sewage waste biochars under two d...

A commonly observed preferential association was quantified between mature native mesquite (Prosopis articulata) trees and the seedlings of six cactus species (Pachycereus pringlei, Opuntia cholla, Lophocereus schottii, Machaerocereus gummosus, Lemaireocereus thurberi, Mammilaria sp.) in a previously-disturbed area of the Sonoran Desert of Baja California, Mexico. We hypothesized that, in addit...

In this research, the uptake of Cu, Mo, Zn, As(III) and Cr(VI) by mesquite (Prosopis spp.) roots and shoots from two different sources was studied. The first source was seeds collected from plants grown in mine tailings in Arizona, USA (Seeds A) and the other source was seeds from a commercial vendor (Seeds B). In addition, the effects of above mentioned elements on plant growth and nutrient up...

Composite edible coatings were formulated with candelilla wax alone, and candelilla wax blended with beeswax, white mineral oil and oleic acid (2:1 ratios) as the lipid phase, and mesquite gum as the structural material and their corrected water vapor permeability (WVPc) were determined. The coatings were applied to Persian limes and their effect upon physiological weight loss, color and chemic...

the aim of this work was to optimize the coagulation-flocculation (cf) process applied tomunicipal wastewaters (ww). optimization of cf was performed to minimize chemical oxygen demand(cod), turbidity, sludge produced, and some metals in sludge. a box-behnken design was used to evaluate the effects and interactions of three factors such as type of biopolymer (guar, mesquite seed gum and opuntia...
