It is an independent committee of experts responsible for assessing the biological status of species at risk in the NWT. The Committee uses the assessments to make recommendations on the listing of species at risk. The Committee uses objective biological criteria in its assessments and does not consider socio-economic factors. Assessments are based on species status reports that include the best available Aboriginal traditional knowledge, community knowledge and scientific knowledge of the species. -

Polyploidy19 Program.Pdf
Preface Yves Van de Peer The study of polyploidy dates back more than 100 years to the work of biologists such as Hugo de Vries and G. Ledyard Stebbins Jr. It has since then been realized that polyploidy is widespread and commonplace in plants. Although polyploidy is much rarer in animals, there are also numerous cases of currently polyploid insects, fishes, amphibians and reptiles. For a long time, ancient polyploidy events, dating back millions of years, were much less well documented and it was not until the advent of genomic technologies that conclusive evidence of ancient whole genome duplications (WGD) events became available and we now have evidence for tens, or even hundreds, of ancient WGD events. Explanations of the short-term success of polyploids are usually centered on the effects of genomic changes and increased genetic variation, which are mediated by changes in gene expression and epigenetic remodeling. Increased genetic variation, together with the direct cytogenetic conse- quences of genome doubling, can potentially affect the morphology and physiology of newly formed polyploids and could lead to alterations of ecologically and envi- ronmentally suitable conditions. For instance, it has repeatedly been proposed that polyploids have increased environmental robustness than do diploids, potentially leading to evolutionary advantages during periods of environmental turmoil. More- over, polyploidy has also sometimes been linked with higher diversification rates. Long(er)-term implications of WGD might be evolutionary innovation and increase in biological complexity by the biased retention of regulatory and developmental genes, which, given time, might diversify in function or cause rewiring of gene regulatory networks. -
Nested Whole-Genome Duplications Coincide with Diversification And
ARTICLE https://doi.org/10.1038/s41467-020-17605-7 OPEN Nested whole-genome duplications coincide with diversification and high morphological disparity in Brassicaceae Nora Walden 1,7, Dmitry A. German 1,5,7, Eva M. Wolf 1,7, Markus Kiefer 1, Philippe Rigault 1,2, Xiao-Chen Huang 1,6, Christiane Kiefer 1, Roswitha Schmickl3, Andreas Franzke 1, Barbara Neuffer4, ✉ Klaus Mummenhoff4 & Marcus A. Koch 1 1234567890():,; Angiosperms have become the dominant terrestrial plant group by diversifying for ~145 million years into a broad range of environments. During the course of evolution, numerous morphological innovations arose, often preceded by whole genome duplications (WGD). The mustard family (Brassicaceae), a successful angiosperm clade with ~4000 species, has been diversifying into many evolutionary lineages for more than 30 million years. Here we develop a species inventory, analyze morphological variation, and present a maternal, plastome-based genus-level phylogeny. We show that increased morphological disparity, despite an apparent absence of clade-specific morphological innovations, is found in tribes with WGDs or diversification rate shifts. Both are important processes in Brassicaceae, resulting in an overall high net diversification rate. Character states show frequent and independent gain and loss, and form varying combinations. Therefore, Brassicaceae pave the way to concepts of phy- logenetic genome-wide association studies to analyze the evolution of morphological form and function. 1 Centre for Organismal Studies, University of Heidelberg, Im Neuenheimer Feld 345, 69120 Heidelberg, Germany. 2 GYDLE, 1135 Grande Allée Ouest, Québec, QC G1S 1E7, Canada. 3 Department of Botany, Faculty of Science, Charles University, Benátská 2, 128 01, Prague, Czech Republic. -
A Record of Silene Viscaria (L.) Jess. (Caryophyllaceae) with Achromatic Flowers in the Mordovia State Nature Reserve (Central Russia)
Annales Universitatis Paedagogicae Cracoviensis Studia Naturae, 2: 107–113, 2017, ISSN 2543-8832 DOI: 10.24917/25438832.2.8 Anatoliy A. Khapugin Joint Directorate of the Mordovia State Nature Reserve and National Park “Smolny”, Republic of Mordovia, Saransk, Russia, *[email protected]. A record of Silene viscaria (L.) Jess. (Caryophyllaceae) with achromatic flowers in the Mordovia State Nature Reserve (Central Russia) Introduction Silene viscaria (L.) Jess. (syn.: Lychnis viscaria L., Steris viscaria (L.) Ran., Viscar- ia viscosa Asch., V. vulgaris Rohl.) is a perennial 25–80 cm high herb: stem erect, green, not branching in lower portion, glabrous, upper portion of the upper in- ternodes glutinous, with two to ve distinct internodes (Clapham et al., 1981; Gu- banov et al., 2003). It inhabits dry grasslands, open forests, forest clearings, and ledges (Kurtto, Wesenberg, 2001; Gubanov et al., 2003). S. viscaria is distributed in most of Europe excluding the Iberian Peninsula, Northern Scandinavia, Northern Russia, most of South Italy, and Southern Greece (Jalas, Suominen, 1986). More- over, it is an occasional and alien garden species in eastern North America (Mor- ton, 2005). Inorescences are compound dichasia, lax or slightly congested. Each of them bear about 20–25 owers. e owers are pollinated by insects, mainly bumblebees and butteries (Jennersten, 1988). e seeds are dispersed by gravity. In most literature, the colour of S. viscaria owers is indicated as purple, purple-red, pink, or crimson (Clapham et al., 1981; Gubanov et al., 2003; Morton, 2005; Frajman et al., 2013). Only few authors indicate cases of achromatism for S. viscaria owers (Gu- banov et al., 2003; Frajman et al., 2013). -
Neobeckia Aquatica Eaton (Greene) North American Lake Cress
New England Plant Conservation Program Conservation and Research Plan Neobeckia aquatica Eaton (Greene) North American Lake Cress Prepared by: John D. Gabel and Donald H. Les University of Connecticut Storrs, Connecticut For: New England Wild Flower Society 180 Hemenway Road Framingham, MA 01701 508/877-7630 e-mail: [email protected] ! website: www.newfs.org Approved, Regional Advisory Council, 2000 SUMMARY The North American lake cress, Neobeckia aquatica (Eaton) Greene (Brassicaceae), is listed as S1 in Vermont, SH in Massachusetts, and “SH?” in Maine. Lake cress likely requires clear, slow-moving water. A requirement of sites is that they have regular fluctuations in water level. Sites are typically located in gently flowing riverine systems and have little or no shoreline development. Special threats include invasive plant species, eutrophication, and development of habitat. All extant New England element occurrences of lake cress are located in Vermont at four sites. VT.002, Orwell is characterized by small population numbers (two to five plants). The site is highly eutrophic and threatened by invasive aquatic plants (Butomus umbellatus, Lythrum salicaria, and Trapa natans). VT.006, Orwell is characterized by a relatively large population (100-500 plants). The site is threatened by invasive aquatic plants (Butomus umbellatus , Lythrum salicaria, and Trapa natans.) VT.009, Shoreham is a highly eutrophic site with 500-1000 plants in the population. VT.010, Isle La Motte represents a population located in a pristine habitat with around 500 plants. The conservation objectives for Neobeckia aquatica in New England are to: C remove the threat of invasive plants from extant lake cress populations. -

Popp, M. 2001. A revised generic classification of the tribe Sileneae (Caryophyllaceae) - Nord. J. Bot. 20: 743-748. Copenhagen. ISSN-0105-055X. A reclassification of the tribe Sileneae compatible with molecular data is presented. The genus Eudianthe (E. laeta and E. coeli-rosa) is restored. Viscaria, Ixoca (heliosperma), and Atocion together form a well supported monophyletic group distinct from Silene and Lychnis, and are recognized at generic level. With Agrostemma and Petrocoptis, the number of genera in the tribe sums up to eight. The new combinations Silene samojedora, Silene ajanensis, Lychnis abyssinica, Atocion asterias, Atocion compacta, Atocion lerchenfeldiana, and Atocion rupestris are made. B.
