Interisland Variability of Dune Plant Community Structure
INTERISLAND VARIABILITY OF DUNE PLANT COMMUNITY STRUCTURE ON VIRGINIA’S BARRIER ISLANDS Justin K. Shafer Old Dominion University, 2010 Director: Dr. Frank P. Day The barrier islands of the Virginia Coast Reserve LTER site provide an opportunity to study interisland variability of dune plant communities. My research focused on the variation in biomass and diversity of communities among islands a...
متن کاملFragmentation affects plant community composition over time
across ecosystems. In part this deficit is due to the fact that the most frequently used metric in long term datasets, species richness, obscures compositional shifts (Magurran and Henderson 2010, Dornelas et al. 2014). Importantly, changes in community composition can have cascading effects on ecosystem properties (Tabarelli et al. 2012), highlighting a pressing need for a better understanding...
متن کاملEffects of plant host species and plant community richness on streptomycete community structure.
We investigated soil streptomycete communities associated with four host plant species (two warm season C4 grasses: Andropogon gerardii, Schizachyrium scoparium and two legumes: Lespedeza capitata, Lupinus perennis), grown in plant communities varying in species richness. We used actinobacteria-selective PCR coupled with pyrosequencing to characterize streptomycete community composition and str...
متن کاملSoil shapes community structure through Wre
Recurrent wildWres constitute a major selecting force in shaping the structure of plant communities. At the regional scale, Wre favours phenotypic and phylogenetic clustering in Mediterranean woody plant communities. Nevertheless, the incidence of Wre within a Wre-prone region may present strong variations at the local, landscape scale. This study tests the prediction that woody communities on ...
متن کاملCo-community Structure in Time-varying Networks
Networks consisting of vertices and edges connecting some pairs of vertices are powerful abstractions of relational data, hence have become very popular tools in many fields including sociology, biology and physics [1]. The characteristic of community structure in networks, i.e., networks are naturally divided into modules or communities, has attracted huge attention in the past decade which ca...
