Rangeland degradation has been identified as a serious concern in alpine regions of western China on the Qinghai-Tibetan plateau (QTP). Numerous government-sponsored programs have been initiated, including many that feature long-term grazing prohibitions and some that call for eliminating pastoralism altogether. As well, government programs have long favored eliminating plateau pikas (Ochotona ...

Overabundant generalist herbivores can facilitate non-native plant invasions, presumably through direct and indirect modifications to the environment that affect plant performance. However, ecophysiological mechanisms behind ungulate-mediated plant invasions have not been well-studied. At a long-term Odocoileus virginianus (white-tailed deer) exclusion site in a temperate deciduous forest, we q...

We investigated the suitability of Acacia spirorbis Labill., a tropical ectomycorrhizal (ECM) tree, as nurse plant to improve growth Tristaniopsis calobuxus Brongn. & Gris seedlings for restoration nickel mines in New Caledonia. Rehabilitation Caledonia is major concern. In such harsh soil conditions, symbiosis important tree growth, survival, and resistance. To ecological Caledonia, new te...

Specialty forages are those that do not have a wide application in animal production systems of Texas. Other than beef cattle, systems that use cultivated forage can be considered atypical in our state. These include white-tailed deer, game birds (quail or turkey), exotic game, goats, sheep, domesticated rabbits or any other species that is primarily an herbivore. These animals generally requir...

continuous desertification of arable lands mandates use of low quality/ saline water for irrigation, especially in regions experiencing water shortage. using low quality/ saline water for irrigation imposes more stress on plants that are already under stress in these regions. thus, a logical solution will be to find a salt/ drought-tolerant plant species that will survive/sustain under such str...

1. Predators can reduce herbivory and increase plant biomass by consuming herbivores, lowering individual herbivore feeding rates, or both. We tested whether the presence of predators increases plant quality by non-consumptively reducing grazing pressure and thereby weakening the strength of the induced response in plant chemical defences. 2. We performed a 42-day outdoor mesocosm experiment in...

Biotic interactions assembling plant communities can be positive (facilitation) or negative (competition) and operate simultaneously. Facilitative interactions and posterior competition are among the mechanisms triggering succession, thus representing a good scenario for ecological restoration. As distantly related species tend to have different phenotypes, and therefore different ecological re...

Forest rangelands are an important component of extensive goat production in the Mediterranean region. The aim this study was to survey floristic composition, lifespan, life forms, phytogeographic relationships, palatability degree, and forage availability forest Northern Morocco. To achieve goal, a plant species inventory carried out, digital herbarium constructed. Forage estimated using quadr...

Catalan spring onions, or “calcots”, are a very popular kind of vegetables obtained by special agronomic practices that avoid photosynthesis and subsequent metabolism by the Allium cepa plants. They have been considered for more than a century harmless for pets, as pleasant odour and sweet taste differ so largely from any other onion that can be ingested by children and adults in huge quantitie...
