palatability includes plants physical and chemical property that encourages an animal selecta plant for grazing. this study is an attempt for intruducing an indicator for determining thepalatability of rangeland plants. to do this, the relationship between palatability and foragequality of rangeland plants in karsanak rangelands of the chaharmahal-va-bakhtiari provincewas studied. first, plant ...

Tropical volcanoes are an important but understudied ecosystem, and the relationships between plant species diversity and compositional change and elevation may differ from mountains created by uplift, because of their younger and more homogeneous soils. We sampled vegetation over an altitudinal gradient on Mt. Rinjani, Lombok, Indonesia. We modeled alpha- (plot) and beta- (among plot) diversit...

recognition of habitats and conditions of species presences in differentsituations can be effective in proper utilization of vegetation. little is known about thevegetation composition of boralan mountain region located in north west of iran in theborder of turkey and azerbaijan with the altitude range of 800-2000m. the aim of thisstudy therefore was to investigate the floristic composition qua...

plants cover composition, condition, trend, production, and grazing capacity of the rangeland change annually. in this research, the role of temporal rainfall distribution on rangeland production was assessed. this research had down in the rangelands of ilam (with semiarid to semi humid climate) and qom and markazi (with arid to semiarid climate) provinces. by attention on plant cover maps in e...

Excessive herbivory can have transformative effects on forest understory vegetation, converting diverse communities into depauperate ones, often with increased abundance of non-native plants. White-tailed deer are a problematic herbivore throughout much of eastern North America and alter forest understory community structure. Reducing (by culling) or eliminating (by fencing) deer herbivory is e...

Herbivores can profoundly influence plant species assembly, including plant invasion, and resulting community composition. Population increases of native herbivores, e.g. white-tailed deer (Odocoileus virginianus), combined with burgeoning plant invasions raise concerns for native plant diversity and forest regeneration. While individual researchers typically test for the impact of deer on plan...
