Comparative biogeochemical studies performed on the same plant species in remote areas enable pinpointing interspecies and interregional differences of chemical composition. This report presents baseline concentrations of PAHs and trace elements in moss species Hylocomium splendens and Pleurozium schreberi from the Holy Cross Mountains (south-central Poland) (HCM) and Wrangell–Saint Elias National Park and Preserve (Alaska) and Denali National Park and Preserve (Alaska). Total PAH concentrations in the mosses of HCM were in the range of 473–2970 mg kg1 (dry weight basis; DW), whereas those in the same species of Alaska were 80–3390 mg kg1 DW. Nearly all the moss samples displayed the similar ring sequence: 3 > 4...
In North America, the last ice age is the most recent event with severe consequences on boreal species’ ranges. Phylogeographic patterns of range expansion in trembling aspen (Populus tremuloides) suggested that Beringia is likely to be a refugium and the “ice-free corridor” in Alberta may represent a region where small populations persisted during the last glacial maximum (LGM). The purpose of this study was to ascertain whether the origins of trembling aspen in western North America are reflected in the patterns of neutral genetic diversity and population structure. A total of 28 sites were sampled covering the northwestern part of aspen’s distribution, from Saskatchewan to Alaska. Twelve microsatellite markers...
Cladonia pyxidata and Cladonia pocillum are commonly referred to as "pixie cup" lichens. The species are mainly delimited by the morphology of the basal squamules, which are upright and separate or form a rosette-like pattern, respectively. Cladonia pyxidata is reported to prefer acidic soils, whereas C. pocillum grows exclusively on basic soils. By examining the morphological and genetic variation of C. pyxidata and C. pocillum , we assess their species status. We also examine whether the variation in morphology correlates with a change in soil pH. Samples from the Cladonia pyxidata group were collected from across Canada. Phylogenetic and population genetic analyses were conducted using 15 morphological characters...
Nitrogen enters terrestrial ecosystems through multiple pathways during primary succession. We measured accumulation of total soil nitrogen and changes in inorganic nitrogen (N) pools across a 300-y sequence of river terraces in northwest Alaska and assessed the contribution of the nitrogen-fixing shrub Shepherdia canadensis. Our work compared 5 stages of floodplain succession, progressing from a sparsely vegetated silt cap to dense shrubby vegetation, balsam poplar-dominated (Populus balsamifera) and white spruce-dominated (Picea glauca) mixed forests, and old-growth white spruce forest. Total soil N (0–30 cm depth) increased throughout the age sequence, initially by 2.4 g N·m−2·y−1 during the first 120 y of terrace...
The University of Alaska Anchorage, Alaska Natural Heritage Program agreed to conduct a vascular plant survey of the proposed UNAVCO Plate Boundary Observatory GPS monument site at Slope Mountain in Lake Clark National Park and Preserve. The need for a plant survey was precipitated by the discovery of a number of rare plants found on surrounding peaks during vascular plant inventories in 2003 and 2005 (see Carlson et al. 2005 for details). The survey of the UNAVCO site on the northeast peak of Slope Mountain did not reveal any imperiled or critically imperiled vascular plant species. Here, I briefly outline the background of the project and rare plant concerns in the area, location and habitat of the site, survey...

Sexual reproduction in flowering plants depends on investment in reproduction, the mode of pollen transfer, the availabilities of nutrient resources and potential mates, and the spatial scales over which these processes take place. In this thesis, I studied the general reproductive biology of Shepherdia canadensis (L.) Nutt. (Elaeagnaceae) and the suite of pollinators that visit the plants in Ivvavik National Park, Yukon, Canada. Across ten sites, I found that S. canadensis females were larger than males, but males produced more flowers than females at most sites. Males typically occurred at higher frequencies than females with the average male to female sex ratio being 1.19 ± 0.08 (mean ± SE, n = 10 sites). Both...
