The polar desert biome of the Canadian high Arctic Archipelago is currently experiencing some of the great- est mean annual air temperature increases on the planet, threatening the stability of ecosystems residing above temperature-sensitive permafrost. 2. Ice wedges are the most widespread form of ground ice, occurring in up to 25% of the world’s terrestrial near-surface, and their melting (thermokarst) may catalyse a suite of biotic and ecological changes, facilitating major ecosystem shifts. 3. These unknown ecosystem shifts raise serious questions as to how permafrost stability, vegetation diversity and edaphic conditions will change with a warming high Arctic. Ecosystem and thermokarst processes tend to be examined independently, limiting our understanding of a coupled system whereby the effect of climate change on one will affect the outcome of the other. 4. Using in-depth, comprehensive field observations and a space-for-time approach, we investigate the highly structured landscape that has emerged due to the thermokarst-induced partitioning of microhabitats. -
Université De Montréal Inuit Ethnobotany in the North American
Université de Montréal Inuit Ethnobotany in the North American Subarctic and Arctic: Celebrating a Rich History and Expanding Research into New Areas Using Biocultural Diversity par Christian H. Norton Département de sciences biologiques Faculté des arts et des sciences Mémoire présenté à la Faculté des études supérieures en vue de l’obtention du grade de maîtrise en sciences biologiques Novembre 2018 © Christian H. Norton 2018 2 Résumé Historiquement, l'utilisation des plantes par les Inuits était considérée comme minimale. Notre compréhension de l'utilisation des plantes par les Inuits a commencé par suite de la prise en compte de concepts tels que la diversité bioculturelle et les espèces clés, et ces nouvelles idées ont commencé à dissiper les mythes sur le manque d’importance des plantes dans la culture inuite. Les Inuits peuvent être regroupés en quatre régions en fonction de la langue: l'Alaska, l'Arctique ouest canadien, l'Arctique et la région subarctique est canadienne et le Groenland. Le chapitre 1 passera en revue la littérature sur l'utilisation des plantes inuites de l'Alaska au Groenland. Au total, 311 taxons ont été mentionnés dans les quatre régions, ce qui correspond à 73 familles. Les niveaux de diversité étaient similaires dans les quatre régions. Seuls 25 taxons et 16 familles étaient communs à toutes les régions, mais 50%-75% des taxons et 75%-90% familles étaient signalés dans au moins deux régions, et les régions voisines ont généralement un chevauchement plus élevé que les régions plus éloignées. De la même manière, les Inuits des quatre régions ont indiqué comestible, médecine, incendie et design comme principales catégories d'utilisation, ainsi qu'une différenciation commune claire en ce qui concerne les taxons utilisés à des fins spécifiques. -

Kholodny Institute of Botany, National Academy of Sciences of Ukraine, Tereshchenkivska 2, Kyiv 01601, Ukraine, e-mail: [email protected], [email protected], [email protected] Abstract: Pollen grains of 10 species of Pedicularis occurring in Ukraine were investigated using light and scanning electron microscopy. Palynological data on 6 species are reported for the first time. General pollen morphology of the genus Pedicularis is presented. Three types of apertures (2-syncolpate, 3-colpate, and 3-syncolpate) and seven subtypes of sculpture (3-syncolpate pilate, 3-syncolpate microscabrate-tubeculate, 2-syncolpate microscabrate, 2-syncolpate microscabrate-tubeculate, 2-syncolpate microscabrate-tubeculate-perforate, 2-syncolpate microfoveolate, and 2-syncolpate microscabrate-perforate) are indentified. The subgenus Pedicularis is heterogeneous in its types of apertures and sculpture of the surface, which indicates the need of further taxonomic revision of the group.

An Illustrated Key to the Alberta Figworts & Allies
AN ILLUSTRATED KEY TO THE ALBERTA FIGWORTS & ALLIES OROBANCHACEAE PHRYMACEAE PLANTAGINACEAE SCROPHULARIACEAE Compiled and writen by Lorna Allen & Linda Kershaw April 2019 © Linda J. Kershaw & Lorna Allen Key to Figwort and Allies Families In the past few years, the families Orobanchaceae, Plantaginaceae and Scrophulariaceae have under- gone some major revision and reorganization. Most of the species in the Scrophulariaceae in the Flora of Alberta (1983) are now in the Orobanchaceae and Plantaginaceae. For this reason, we’ve grouped the Orobanchaceae, Plantaginaceae, Phrymaceae and Scrophulariaceae together in this fle. In addition, species previously placed in the Callitrichaceae and Hippuridaceae families are now included in the Plantaginaceae family. 01a Plants aquatic, with many or all leaves submersed and limp when taken from the 1a water; leaves paired or in rings (whorled) on the stem, all or mostly linear (foating leaves sometimes spatula- to egg-shaped); fowers tiny (1-2 mm), single or clustered in leaf axils; petals and sepals absent or sepals fused in a cylinder around the ovary; stamens 0-1 . Plantaginaceae (in part) . - Callitriche, Hippuris 01b Plants emergent wetland species (with upper stems and leaves held above water) or upland species with self-supporting stems and leaves; leaves not as above; fowers larger, single or in clusters; petals and sepals present; stamens 2-4 (Hippuris sometimes emergent, but leaves/ fowers distinctive) . .02 2a 02a Plants without green leaves . Orobanchaceae (in part) . - Aphyllon [Orobanche], Boschniakia 02b Plants with green leaves . 03 03a Leaves all basal (sometimes small, unstalked stem leaves present), undivided (simple), with edges ± smooth or blunt-toothed; fowers small (2-5 mm wide), corollas radially symmetrical, sometimes absent. -

BAILEY USDA Forest Service, 234 Mirror Lake Road, North Woodstock, NH 03262 e-mail: [email protected] JOANN HOY 21 Steam Mill Road, Auburn, NH 03032 CHARLES V. COGBILL 82 Walker Lane, Plainfield, VT 05667 ABSTRACT. The influence of substrate lithology on the distribution of many vascular and nonvascular plants has long been recognized, especially in alpine, subalpine, and other rocky habitats. In particular, plants have been classified as dependent on high-calcium substrates (i.e., calcicoles) based on common restriction to habitats developed in calcareous rocks, such as limestone and marble. In a classic 1907 paper on the influence of substrate on plants, M. L. Fernald singled out a particular meadow on Mont de la Table in the Chic-Choc Mountains of Que´bec for its unusual co-occurrence of strict calcicole and calcifuge (i.e., acidophile) plant taxa. We re-located this site, investigated substrate factors responsible for its unusual plant diversity, and documented current plant distributions. No calcareous rocks were found on site. However, inclusions of calcareous rocks were found farther up the mountain. The highest pH and dissolved calcium concentrations in surface waters were found in a series of springs that deliver groundwater, presumably influenced by calcareous rocks up the slope. Within the habitat delineated by common occurrences of calcicole species, available soil calcium varied by a factor of five and soil pH varied by almost 1.5 units, depending on microtopography and relative connection with groundwater. -

Fens and their rare plants in the Beartooth Mountains, Shoshone National Forest, Wyoming. Gen. Tech. Rep. RMRS-GTR-369. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 110 p. Abstract Fens are common wetlands in the Beartooth Mountains on the Shoshone National Forest, Clarks Fork Ranger District, in Park County, Wyoming. Fens harbor plant species found in no other habitats, and some rare plants occurring in Beartooth fens are found nowhere else in Wyoming. This report summarizes the studies on Beartooth fens from 1962 to 2009, which have contributed to current knowledge of rare plant distributions and biodiversity conservation. The study area is the Wyoming portion of the Beartooth Mountains in the Middle Rocky Mountains. Here, we profile 18 fens that occur over the range of elevations, settings, geomorphic landforms, and vegetation. The wetland flora from these 18 fens is composed of 58 families, 156 genera, and 336 vascular plant species—more than 10 percent of the known Wyoming flora. We discuss 32 rare vascular plant species and 1 bryophyte species associated with Beartooth fens and their State and regional significance. Protection and management of Beartooth fens are addressed in guidance documents prepared by the U.S. -

Msc Thesis, Quinn Barber
Assessing the vulnerability of rare plants using climate change velocity, habitat connectivity and dispersal ability by Quinn Edward Cameron Barber A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Forest Biology and Management Department of Renewable Resources University of Alberta © Quinn Edward Cameron Barber, 2015 Abstract Climate change generally requires species to migrate northward or to higher elevation to maintain constant climate conditions, but migration requirement and migration capacity of individual species can vary greatly. Individual pop- ulations of species occupy different positions in the landscape that determine their required range shift to maintain similar climate, and likewise the mi- gration capacity depends on habitat connectivity. Here, I demonstrate an approach to quantify species vulnerabilities to climate change for 419 rare vascular plants in Alberta, Canada based on multivariate velocity of climate change, local habitat fragmentation, and migration capacity. Climate change velocities indicated that future migration requirements ranged from 1 to 5 km yr-1 in topographically complex landscapes, such as the Alberta Foothills and Rocky Mountains. In contrast, migration requirements to maintain constant climate in relatively flat Boreal Plains, Parkland and Grassland ranged from 4 to 8 km yr-1. Habitat fragmentation was also highest in these flat regions, particularly the Parkland Natural Region. Of the 419 rare vascular plants assessed, 36 were globally threatened (G1 to G3 ranking). Three of these globally threatened species were ranked as extremely vulnerable and five as highly vulnerable to the interactions among climate change velocity, habitat fragmentation and migration capacity. Incorporating dispersal characteristics and habitat fragmentation with local patterns in climate change velocity rep- resents a streamlined vulnerability assessment approach that may be applied to guide conservation actions, particularly where detailed species-specific data is limited. -
