ative and naturalized plant diversity are positively correlated in scrub communities of California and Chile
An emerging body of literature suggests that the richness of native and naturalized plant species are often positively correlated. It is unclear, however, whether this relationship is robust across spatial scales, and how a disturbance regime may affect it. Here, I examine the relationships of both richness and abundance between native and naturalized species of plants in two mediterranean scru...
متن کاملPhylogenetic patterns differ for native and exotic plant communities across a richness gradient in Northern California
The assembly of local communities is the result of the tension between local, often negative, and possibly deterministic interactions, and larger-scale environmental or dispersal constraints or stochastic events (Berlow, 1997; Levine, 2000; Lovette & Hochachka, 2006). Larger-scale environmental conditions and dispersal limitation filter a larger pool of potential colonists into one that include...
متن کاملAssembly of Plant Communities
• Communities are located within a larger species pool of potential colonists. The study of community assembly considers the mechanisms by which local communities are formed from the species pool. • Dispersal from the species pool, abiotic tolerance of colonists, and biotic interactions can all influence membership in local communities. • Phenotypic similarities and differences of co-occurring ...
متن کاملSensitive Plant Communities
Over half of the southern landscape is forested, but nearly all of the land has been modified considerably, especially during the centuries following European settlement (See history chapters). Such extensive changes in the southern landscape have contributed to the threatened status of many plant and animal species that are now protected under the Endangered Species Act. Additionally these cha...
متن کاملPlant Communities in Eastern Mongolia
In this contribution is presented a phytosociological description of plant communities, recorded in the phytogeographical district of Eastern Mongolia, including parts of the Dornod (Eastern) and the Choybalsan aymags. The whole district is characterized by steppe vegetation. Other vegetation types, like elm (Ulmus pumila) bush vegetation, shrubbery on sandy and rocky sites, Salix miyabeana bus...
