Other claims from this paper (13)
- Observation Phylogenetic analyses revealed eight distinct species within P. eugyrium and P. subeugyrium.
- Observation Accessions previously assigned to P. eugyrium form three allopatric lineages associated with temperate Europe, eastern North America and eastern Asia.
- Observation Accessions assigned to P. subeugyrium contain five phylogenetic lineages.
- Observation Three of the P. subeugyrium lineages occur under harsh Asian continental climates from cool-temperate to Arctic regions.
- Observation The remaining two P. subeugyrium lineages have more oceanic North Atlantic and East Asian distributions.
- Observation Niche identity and similarity tests suggested no similarity in the distributions of phylogenetically related lineages.
- Observation Niche tests revealed the identity of two East Asian Pseudohygrohypnum species.
- Observation Niche tests revealed similarity of two pairs of unrelated Pseudohygrohypnum species.
- Observation A morphological survey confirmed the distinctness of all eight phylogenetic lineages.
- Observation Pseudohygrohypnum appalachianum and P. orientale are described as new species for North American and East Asian plants.
- Observation Phylogenetic dating suggests that diversification of subaquatic Pseudohygrohypnum lineages appeared in the late Miocene.
- Observation Mesophilous Pseudohygrohypnum species split before Miocene cooling.
- Mechanism Radiation of the P. subeugyrium complex in temperate Asia might have been driven by progressive cooling, aridification and increased seasonality and gradients.
