Mesic forests in the North American Pacific Northwest occur in two disjunct areas: along the coastal and Cascade ranges of Oregon, Washington, and British Columbia as well as the Northern Rocky Mountains of Idaho, Montana, and British Columbia. Over 150 species or species complexes have disjunct populations in each area, and a priori hypotheses based on phytogeography and geology potentially ex...

For years, studies on the classification, evolution and geographic history of the Caribbean biota have ignited much interest, resulting in many studies addressing issues in a variety of contexts. Most of the works on biogeography of the region are predominantly on animal groups, and there is a marked deficiency in similar studies for plant groups. For instance, in the proceedings of a symposium...

The increasing number of quantitative assessments of homogenization using citizen science data is particularly important in the Neotropics, given its high biodiversity and ecological peculiarity, and whose communities may react differently to landscape changes. We looked for evidence of taxonomic homogenization in terrestrial birds by investigating patterns of beta diversity along a gradient of...

Ground-ivy ( Glechoma hederacea L.) is a widespread stoloniferous plant that grows in several ecologically diverse habitats: the open, at forest edge, and understorey. The vegetation of ground-ivy habitats was studied NE Slovenia terms floristic richness diversity, biological spectrum, phytogeography syntaxonomy. We identified five clusters distinct with occurrence ground-ivy, differentiated ac...

BACKGROUND Orchids have numerous species, and their speciation rates are presumed to be exceptionally high, suggesting that orchids are continuously and actively evolving. The wide diversity of orchids has attracted the interest of evolutionary biologists. In this study, a new orchid was discovered on Danxia Mountain in Guangdong, China. However, the phylogenetic clarification of this new orchi...
