Biodiversity surrogate effectiveness in two habitat types of contrasting gradient complexity

摘要: Enormous and increasing loss of biodiversity requires evaluation surrogate taxa as a tool for conservation biology new reserve selection, in spite the fact that this approach has become questionable. The aim study was to assess effect gradient complexity on species richness community composition among three taxonomic groups. We compared efficiency vascular plants indicate diversity cryptogams (bryophytes, lichens) snails two contrasting habitat types (treeless fens forests) within same geographic region. examined correlation their (Spearman rank correlation), (Bray–Curtis similarity, Mantel test) responses environmental variables (detrended canonical correspondence analysis). also focused Red List species. found spatial congruence studied affected by type, however were good indicator snail both habitats. Nevertheless, all significant positive correlations associated with main gradients. Although there consistency significantly cross-taxon insufficient purposes. Furthermore we confirmed necessity integration at-risk planning poor indicators total vice versa. suggest complementation existing network small-scale protected areas ecosystems, communities or In not sufficient fine-filter other taxa.
