An additional 17 km of native prairie is noted on the Vantage Pipeline Project (Jacques Whitford – Axys 2009) in contiguous portions of pipeline that could not be assessed in 2010. This area will be assessed in 2011. The construction and operation of the Project may contribute to the direct and indirect losses or alteration of plant species and their associated vegetation, the further fragmentation of native prairie, and the introduction of noxious and invasive non-native species. The field work in 2010 was limited by difficulities in obtaining land access, and the timing of the field surveys. Additionally, pipeline route revisions have been made after field work was completed. Consequently, not all quarter sections traversed by the Project were ground-truthed or surveyed. Due to the senescence of vegetation, some tracts of native prairie to which access was granted, were also not surveyed in 2010. Approximately 75 % of the vegetation and rare plant surveys for the identified areas of native prairie were completed in 2010. An additional 10.9 % of the entire pipeline, which may also contain areas of native prairie remains to be assessed or surveyed in 2011. A total of 22 rare plant species were identified during the 2010 field surveys. An additional species has previously been reported to be in the vicinity of the pipeline route, but was not found in 2010. Although rare ecological communities are not currently tracked in Saskatchewan, eight communities of interest were identified along the Project route. The data collected during the 2010 surveys will be used to determine priority areas for rare plant surveys in 2011. Surveys will include early-season rare plant surveys for the complete route, as well as late-season surveys for the areas of the route that were not surveyed in 2010. Survey sites will include a sample of all landuse types to ensure the detection of any rare species, which may occur. Additionally, communities of interest will be confirmed and mapped in detail for those communities that are determined to be distinctive. Given some discrepancies in the location of the proposed pipeline, and possible errors, which GPS accuracy may have introduced, surveyed areas will be analyzed to ensure that the surveyed sites reflect the actual route of the pipeline. There were 29 noxious weed species identified during the intial baseline weed surveys conducted in 2010. Weed surveys will continue in 2011 for those areas that were not accessible in 2010, and a preconstruction weed survey will be completed prior to construction. Mitigation measures to minimize disturbance to native vegetation have been described in the Vegetation section of the Environmental and Socio-Economic Assessment (Section 13.3.5) and the Environmental Protection Plan (EPP) (Appendix A). Site specific mitigation measures have not been identified at this time, and will be determined at the conclusion of the 2011 field surveys. 23 Vantage Pipeline Project Environmental and Socio-Economic Assessment Appendix I: Vegetation Baseline Information and Field Results 5 REFERENCES 5.1 Literature Cited Adams, B.W., Poulin-Klein, L., Moisey, D., and R.L.

We depended on 80 qualitative and quantitative morphological characters with 172 character states. The genetic polymorphism and gene diversity was assessed using five polymorphic inter simple sequence repeat primers. Based on Morphological observations, the studied species were separated into two groups, the first combines L. perenne, L. multiflorum and L. rigidum, where, L. perenne is more associated to L. multiflorum than to L. rigidum; the second combines L. temulentum and L. persicum; to some extent geographical distribution influenced the relationships among the populations. High degree of gene diversity with polymorphism percentage of 95.62% was detected among the studied species. Genetically, high degrees of genetic distance are observed among the studied populations; the geographical distribution has a great influence on the population’s relationships.

Hilu Eric P. Beers Carla V. Finkielstein Jill C. Sible December 2, 2011 Blacksburg, Virginia Keywords: (phylogeny, missing data, caryophyllids, trnK intron, matK, RNA editing, gnetophytes) Copyright 2011, Sunny Sheliese Crawley Rethinking phylogenetics using Caryophyllales (angiosperms), matK gene and trnK intron as experimental platform Sunny Sheliese Crawley ABSTRACT The recent call to reconstruct a detailed picture of the tree of life for all organisms has forever changed the field of molecular phylogenetics. Sequencing technology has improved to the point that scientists can now routinely sequence complete plastid/mitochondrial genomes and thus, vast amounts of data can be used to reconstruct phylogenies. These data are accumulating in DNA sequence repositories, such as GenBank, where everyone can benefit from the vast growth of information. The trend of generating genomic-region rich datasets has far outpaced the expasion of datasets by sampling a broader array of taxa. We show here that expanding a dataset both by increasing genomic regions and species sampled using GenBank data, despite the inherent missing DNA that comes with GenBank data, can provide a robust phylogeny for the plant order Caryophyllales (angiosperms). We also investigate the utility of trnK intron in phylogeny reconstruction at relativley deep evolutionary history (the caryophyllid order) by comparing it with rapidly evolving matK. We show that trnK intron is comparable to matK in terms of the proportion of variable sites, parsimony informative sites, the distribution of those sites among rate classes, and phylogenetic informativness across the history of the order.

THOMAS Institute of Botanical Training, LLC 111 County Road 3260 Salem, Missouri 65560 [email protected] ABSTRACT An annotated checklist of the 2,961 vascular taxa comprising the flora of Missouri is presented, with conservatism rankings for Floristic Quality Assessment. The list also provides standardized acronyms for each taxon and information on nativity, physiognomy, and wetness ratings. Annotated comments for selected taxa provide taxonomic, floristic, and ecological information, particularly for taxa not recognized in recent treatments of the Missouri flora. Synonymy crosswalks are provided for three references commonly used in Missouri. A discussion of the concept and application of Floristic Quality Assessment is presented. To accurately reflect ecological and taxonomic relationships, new combinations are validated for two distinct taxa, Dichanthelium ashei and D. werneri , and problems in application of infraspecific taxon names within Quercus shumardii are clarified.

Phylogenetic analysis of the matK sequences alone and in combination using maximum parsimony methods produced monophyletic lineage of Amaranthaceae-Chenopodiaceae. Our results indicated that a polyphyletic Celosieae as sister to an Amaranthus-Chemissoa lineage. Subfamily Amaranthoideae is paraphyletic to the core Gomphrenoids. This study also shows that the polyphyly of Amarantheae is apparent and so is the polyphyly of Amaranthinae.

  • 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.
