The Arctic Flora of Canada and Alaska Project.

<b>Abstract:</b><div>The Arctic Flora of Canada and Alaska project aims to produce a new flora treating all vascular plants (ca. 800 species) in the Arctic ecozone in Canada and northern Alaska. Our research team includes botanists from Canada, Norway, and the United States, and is being led by researchers at the Canadian Museum of Nature. We are using a web platform to move the Flora beyond traditional standards, and to produce a treatment that is digital and interactive, taking full advantage of current web and database technologies. The flora will include parallel taxon descriptions, dichotomous keys, detailed nomenclatural data, common names, information on traditional uses, taxonomic comments, and will be richly illustrated with photographs taken in the field and of herbarium specimens showing characters important for accurate identification. Tracking specimens examined will allow future verification of distributional and descriptive data, and will facilitate production of dynamic distribution maps. The Arctic Flora of Canada and Alaska website (http://arcticplants.myspecies.info) will be updated with content on an ongoing basis. The Flora will eventually serve as the key source of information for anybody who requires accurate and up-to-date information on the Arctic flora, including those involved in Arctic terrestrial monitoring, students in the north and elsewhere, and the international botanical community. It will also serve as an up-to-date source of baseline information on plant biodiversity in one of the worlds’ most climate-threatened ecosystems.<div><i><br></i></div><div><i>Poster presented at the XIX International Botanical Congress, Shenzhen, China, 23–29 July 2017. </i></div></div

Vascular plant biodiversity and floristics of the Canadian Arctic

<p><b>Abstract:</b></p><p>Despite nearly 200 years of exploration, substantial gaps remain in our understanding of the diversity and distribution of the vascular plant flora of the Canadian Arctic, which comprises over one third of the global Arctic ecozone. Detailed information on the diversity and distribution of Arctic plants is urgently needed to understand the potential impacts of climate change on the region’s flora. Since 2008 we have been conducting detailed floristic surveys in botanically-understudied regions of the Canadian Arctic. The comprehensive baseline data of our >8000 new collections, all housed in the National Herbarium of Canada and other herbaria in Canada and internationally, adds important knowledge to our understanding of Arctic plant biodiversity. Many of our collections represent first records for specific areas, others represent the second or third collections of poorly-known species at the edge of their ranges in the Canadian Arctic, and many fill in gaps in the known distributions of Arctic species. We will summarize our floristic work to date in the context of current understanding of the Canadian Arctic flora, with a focus on our many particularly noteworthy discoveries. </p><p><i>Poster presented at XIX International Botanical Congress, Shenzhen, China, 23–29 July 2017.<br></i></p><p><br></p><p><br></p

A molecular phylogenetic study of temperate grasses in Poeae chloroplast group 1 (Poaceae: Pooideae: Poeae) based on nuclear ribosomal and plastid DNA sequence data

<div><b>Abstract:</b><br></div>We conducted phylogenetic analyses of >2500 new DNA sequences from nuclear ribosomal (ITS and ETS) and five plastid regions to clarify relationships within and among genera and subtribes that are part of the grass tribe Poeae chloroplast group 1 and allies. A large clade comprises the subtribes Agrostidinae and Calothecinae, neither of which is monophyletic. The type species of Deyeuxia is allied with species of Calamagrostis s.s., thus Deyeuxia is a synonym of Calamagrostis, and relationships among species of Calamagrostis s.str. and related genera are mostly poorly resolved. Agrostis and Polypogon are distinct from Calamagrostis s.s. but are not reciprocally monophyletic. Species of Agrostis and Polypogon are intermixed in a strongly supported clade in plastid trees, including Lachnagrostis, and there is incongruence among data partitions in a subset of species. Ammophila and Calamagrostis s.str. are not distinguished as separate genera, and Calamagrostis coarctata, Dichelachne, Echinopogon and Relchela are closely related. Taxa of Sesleriinae are allied with Aveninae s.s. (Arrhenatherum, Avena, Helictotrichon, Tricholemma) in nuclear ribosomal trees, and with taxa of chloroplast group 2 in plastid trees. Koeleriinae is strongly supported and includes two major subclades: clade A comprises Avellinia, Gaudinia, Graphephorum and Trisetum sect. Trisetum p.p. (nuclear trees), Koeleria, Rostraria, Trisetaria, Trisetum sect. Trisetum p.p. and Trisetum sect. Trisetaera, and Koeleriinae clade B comprises Calamagrostis/Deyeuxia p.p., Graphephorum and Trisetum sect. Trisetum p.p. (plastid trees), Peyritschia, Leptophyllochloa, Sphenopholis, Trisetopsis and Trisetum sect. Deschampsioides. Within each clade most aspects of relationship are unresolved, and conflict between data partitions is identified. Affinities of Lagurus ovatus with respect to Aveninae s.s. and Koeleriinae are incongruent in nuclear ribosomal and plastid trees. All but one of the eight sampled species of Deyeuxia sect. Stylagrostis are part of the Deschampsia lineage, and these are transferred to Deschampsia. Substantial changes to the current classification will be needed to produce generic circumscriptions consistent with phylogenetic evidence.<div><br></div><div><i>Presentation delivered at XIX International Botanical Congress, Shenzhen, China, 23–29 July 2017, in a symposium entitled "Poaceae: systematics and phylogeny of major lineages".</i> </div><div><i><br></i></div><div><b>Related publication:</b></div><div>Saarela JM, Bull RD, Paradis MJ, Ebata SN, Peterson PM, Soreng RJ, Paszko B, .
