Ecological differentiation and sympatry of cryptic species in the Sphagnum magellanicum complex (Bryophyta).

Journal Article American journal of botany · September 2024 PremiseSphagnum magellanicum (Sphagnaceae, Bryophyta) has been considered to be a single semi-cosmopolitan species, but recent molecular analyses have shown that it comprises a complex of at least seven reciprocally monophyletic groups, that are d ...

Parallel patterns of genetic diversity and structure in circumboreal species of the Sphagnum capillifolium complex.

Journal Article American journal of botany · May 2024 PremiseShared geographical patterns of population genetic variation among related species is a powerful means to identify the historical events that drive diversification. The Sphagnum capillifolium complex is a group of closely related peat mosse ... Full text Cite

The Sphagnum cuspidatum complex: phylogeny, species delimitation, and morphology

Journal Article Biological Journal of the Linnean Society · April 1, 2024 The use of species as a concept is an important metric for assessing biological diversity and ecosystem function. However, delimiting species based on morphological characters can be difficult, especially in aquatic plants that exhibit high levels of varia ... Full text Cite

Clonality, local population structure and gametophyte sex ratios in cryptic species of the Sphagnum magellanicum complex.

Journal Article Annals of botany · October 2023 Background and aimsSphagnum (peatmoss) comprises a moss (Bryophyta) clade with ~300-500 species. The genus has unparalleled ecological importance because Sphagnum-dominated peatlands store almost a third of the terrestrial carbon pool and peatmoss ... Full text Cite

Sphagnum diabolicum sp. nov. and S. magniae sp. nov.; morphological variation and taxonomy of the "S. magellanicum complex"

Journal Article Bryologist · February 20, 2023 Until a few years ago, Sphagnum magellanicum was understood to be a single widespread species with an intercontinental range. Recent work by Norwegian sphagnologists showed that S. magellanicum s.str. is restricted to southern South America and plants know ... Full text Cite

Newly identified sex chromosomes in the Sphagnum (peat moss) genome alter carbon sequestration and ecosystem dynamics.

Journal Article Nature plants · February 2023 Peatlands are crucial sinks for atmospheric carbon but are critically threatened due to warming climates. Sphagnum (peat moss) species are keystone members of peatland communities where they actively engineer hyperacidic conditions, which improves their co ... Full text Cite

Phylogenomic structure and speciation in an emerging model: the Sphagnum magellanicum complex (Bryophyta).

Journal Article The New phytologist · November 2022 Sphagnum magellanicum is one of two Sphagnum species for which a reference-quality genome exists to facilitate research in ecological genomics. Phylogenetic and comparative genomic analyses were conducted based on resequencing data from 48 samples and RADs ... Full text Cite

Morphological-molecular incongruence in Sphagnum majus ssp. majus and ssp. norvegicum

Journal Article Bryologist · April 1, 2022 Species delimitation is problematic in many plant groups and among the mosses, Sphagnum is one of the more contentious genera because of high levels of morphological variation. The allopolyploid species, Sphagnum majus, comprises one such problematic compl ... Full text Cite
