In temperate forests, herbs comprise up to 90% of species richness yet received less attention, and their community structure, diversity patterns, driving mechanisms still remain understudied. We provide a phytosociological overview herb stratum develop vegetation model characterize designate groups interpret distribution patterns. Multivariate analyses – classification (TWINSPAN) ordination (i...

BACKGROUND AND AIMS Plant parasitism and arbuscular mycorrhizal (AM) associations have many parallels and share a number of regulatory pathways. Despite a rapid increase in investigations addressing the roles of AM fungi in regulating interactions between parasitic plants and their hosts, few studies have tested the effect of AM fungi on the initiation and differentiation of haustoria, the para...

DNA barcoding is expected to be one of the most promising tools in biological taxonomy. However, there have been no agreements on which core barcode should be used in plants, especially in species-rich genera with wide geographical distributions. To evaluate their discriminatory power in large genera, four of the most widely used DNA barcodes, including three plastid regions (matK, rbcL, trnH-p...

Accurate identification of Arctic plant species is critical for understanding potential climate-induced changes in their diversity and distributions. To facilitate rapid identification we generated DNA barcodes for the core plastid barcode loci (rbcL and matK) for 490 vascular plant species, representing nearly half of the Canadian Arctic flora and 93% of the flora of the Canadian Arctic Archip...

Contribution des explorateurs français à l'étude de la flore l'Asie Centrale: les collections d'herbier Guillaume Capus (1857-1931). Les explorations en Asie Centrale entre 1880 et 1887 ont notamment abouti une collection remarquable 3000 spécimens d'herbiers, toujours conservés dans l'Herbier Paris (France). récoltes sa première exploration été rapidement déterminées par un autre botaniste fra...
