Covariation between intraspecific genetic diversity and species diversity within a plant functional group

摘要: 1. Species diversity and genetic are fundamental components of biodiversity. A primary goal biodiversity studies is to explain the distribution species alleles in space time. new challenge cross discipline boundaries explore relationship between these two scales diversity. 2. In biodiverse northern sandplain shrublands south-western Australia, woody shrub Banksia attenuata occurs on patchily distributed sand dunes, coexists with B. hookeriana, menziesii, small tree species, Eucalyptus todtiana Xylomelum angustifolium, which together comprise a plant functional group large shrubs/small trees. 3. Genetic variation (alleles per locus heterozygosity) 736 individuals 27 discrete dunes was assessed using 11 polymorphic microsatellite markers. For each dune, physical properties area height, (richness evenness) group, were measured. 4. Synthesis. covaried positively diversity, turn strongly dune height rather than area. The positive demonstrated here supports theory common environmental, neutral, processes acting directly or indirectly both suggests possibility predicting one component basis other.
