Landscape-Level Impacts Of Mesquite Canopy Cover On Herbaceous Species Composition, D. B. Murray, C. E. Cooper
Landscape-Level Impacts Of Mesquite Canopy Cover On Herbaceous Species Composition, D. B. Murray, C. E. Cooper
IGC Proceedings (1993-2023)
Woody encroachment of mesquite (Prosopis) and acacia (Acacia) species into grasslands has widespread and ongoing impacts on grassland ecosystems. Changes in the herbaceous layer are associated with changes in the canopy cover of these sparse-canopied species, which do not exclude the herbaceous component, but often change species composition under the canopy relative to surrounding open areas. These effects are often differential based on productivity of the site and herbaceous species composition of the grassland. Here we investigated landscape-scale changes in the herbaceous composition resulting from changes in canopy cover of honey mesquite (Prosopis glandulosa) …
Investigating The Effects Of Ant-Hemipteran Mutualisms On The Invertebrate Community Structure And Their Host Plant, Honey Mesquite (Prosopis Glandulosa), Nabil Nasseri
Graduate College Dissertations and Theses
Ants are ubiquitous in most communities and many form opportunistic mutualisms with honeydew-producing hemipterans (e.g. treehoppers). Hemipterans excrete honeydew, a carbohydrate rich substance, that ants harvest and, in return, ants protect their honeydew-producing partners from parasitoids, predators, and competitors. Given the efficacy of tending ants in removing hemipteran antagonists, and the strong roles that ants play within their communities as predators, competitors, and seed dispersers, surprisingly little is known of the effects of ant-hemipteran mutualisms (AHM) on the invertebrate communities in which they are embedded or on the plants that host AHM. Using observational and manipulative field experiments, I examined …
Impact Of Ground Water Depletion On The Mesquite Community At Edwards Air Force Base, Western Mojave Desert, California, Jonathan E. Campbell, M. Rasoul Sharifi, Philip W. Rundel
Impact Of Ground Water Depletion On The Mesquite Community At Edwards Air Force Base, Western Mojave Desert, California, Jonathan E. Campbell, M. Rasoul Sharifi, Philip W. Rundel
Aliso: A Journal of Systematic and Floristic Botany
Edwards Air Force Base (EAFB) provides a habitat refugium for mesquite woodlands in the western Mojave Desert of the Antelope Valley. Although many mesquite communities in the arid southwest are considered invasive as they reduce the extent of grazing lands, the community at EAFB is composed primarily of large, widely spaced trees that provide food and shelter for local wildlife species and recreational opportunities for base personnel. Unfortunately, the range of these mesquite trees appears to be contracting as mature and old individuals dominate the community. Although anecdotal evidence suggests that the fall in the local groundwater table is responsible …
Symbiotic Effects Of The Fungus Glomus Sp. On Chromium(Iii), Chromium(Vi), And Lead(Ii) Uptake By Mesquite (Prosopis Sp.): A Novel Method To Remediate Heavy Metals, Jack A. Arias
Open Access Theses & Dissertations
The indiscriminate disposal of lead (Pb) and chromium (Cr) containing wastes has resulted in a detrimental impact on environmental health. Lead and Cr are in the EPA priority list due to their degree of toxicity on humans, animals, plants, and other living organisms. The removal of toxic wastes involves technologies that are expensive, sometimes incomplete, and could represent health hazards. In addition, site restoration after contaminant removal encompasses time and technological resources. Phytoremediation, the use of plants alone or associated with microorganisms, represents a potentially cost-effective option in the long term management of contaminated sites. Various plants known as "hyperaccumulators" …
Mesquite - Aerial Spray To Be Tested
Mesquite - Aerial Spray To Be Tested
Journal of the Department of Agriculture, Western Australia, Series 3
An intensification of the spread of Mesquite in the North-West of the State was reported by the Chief Weed Control Officer of the Department of Agriculture (Mr. G. R. W. Meadly). He stated that a spineless form of this tree had been introduced on certain North-West stations some years ago as it was thought that the plant would provide valuable topfeed in its highly nutritious pods and beans. Unfortunately, the trees had reverted to the spined type and dense thickets had developed in some areas. Approval was recently given for experiments in aerial spraying of these thickets in an attempt …
