Taxonomic and phylogenetic composition show biotic resistance to exotic invasion in acid seep springs

Abstract Background Few studies have incorporated the evolutionary insights provided by analysis of phylogenetic structure along with community composition to assess effects exotic invasion on freshwater wetlands. Here, we taxonomic and relationships among acid seep springs investigate potential homogenization or resistance communities due an grass. Results Multivariate analyses indicated differences in dispersion springs, associated gradients soil moisture, canopy cover, diversity. By contrast, univariate showed diversity but not springs. Conclusions Despite invasion, individual remained taxonomically phylogenetically distinct from each other. Taxonomic metrics revealed different aspects composition, reinforcing importance including both plant for understanding assembly following management purposes. Within appear be driven more through environmental filtering light moisture than competitive grass support Elton’s biotic hypothesis.
