Wild Species 2010 the GENERAL STATUS of SPECIES in CANADA
Wild Species 2010 THE GENERAL STATUS OF SPECIES IN CANADA Canadian Endangered Species Conservation Council National General Status Working Group This report is a product from the collaboration of all provincial and territorial governments in Canada, and of the federal government. Canadian Endangered Species Conservation Council (CESCC). 2011. Wild Species 2010: The General Status of Species in Canada. National General Status Working Group: 302 pp. Available in French under title: Espèces sauvages 2010: La situation générale des espèces au Canada. ii Abstract Wild Species 2010 is the third report of the series after 2000 and 2005. The aim of the Wild Species series is to provide an overview on which species occur in Canada, in which provinces, territories or ocean regions they occur, and what is their status. Each species assessed in this report received a rank among the following categories: Extinct (0.2), Extirpated (0.1), At Risk (1), May Be At Risk (2), Sensitive (3), Secure (4), Undetermined (5), Not Assessed (6), Exotic (7) or Accidental (8). In the 2010 report, 11 950 species were assessed. Many taxonomic groups that were first assessed in the previous Wild Species reports were reassessed, such as vascular plants, freshwater mussels, odonates, butterflies, crayfishes, amphibians, reptiles, birds and mammals. Other taxonomic groups are assessed for the first time in the Wild Species 2010 report, namely lichens, mosses, spiders, predaceous diving beetles, ground beetles (including the reassessment of tiger beetles), lady beetles, bumblebees, black flies, horse flies, mosquitoes, and some selected macromoths. The overall results of this report show that the majority of Canada’s wild species are ranked Secure. -

Endemic Genera of Bryophytes of North America (North of Mexico)
Preslia, Praha, 76: 255–277, 2004 255 Endemic genera of bryophytes of North America (north of Mexico) Endemické rody mechorostů Severní Ameriky Wilfred Borden S c h o f i e l d Dedicated to the memory of Emil Hadač Department of Botany, University Boulevard 3529-6270, Vancouver B. C., Canada V6T 1Z4, e-mail: [email protected] Schofield W. B. (2004): Endemic genera of bryophytes of North America (north of Mexico). – Preslia, Praha, 76: 255–277. There are 20 endemic genera of mosses and three of liverworts in North America, north of Mexico. All are monotypic except Thelia, with three species. General ecology, reproduction, distribution and nomenclature are discussed for each genus. Distribution maps are provided. The Mexican as well as Neotropical genera of bryophytes are also noted without detailed discussion. K e y w o r d s : bryophytes, distribution, ecology, endemic, liverworts, mosses, reproduction, North America Introduction Endemism in bryophyte genera of North America (north of Mexico) appears not to have been discussed in detail previously. Only the mention of genera is included in Schofield (1980) with no detail presented. Distribution maps of several genera have appeared in scattered publications. The present paper provides distribution maps of all endemic bryophyte genera for the region and considers the biology and taxonomy of each. When compared to vascular plants, endemism in bryophyte genera in the region is low. There are 20 genera of mosses and three of liverworts. The moss families Andreaeobryaceae, Pseudoditrichaceae and Theliaceae and the liverwort family Gyrothyraceae are endemics; all are monotypic. A total of 16 families of mosses and three of liverworts that possess endemic genera are represented. -
On the Evolution and Circumscription of the Neckeraceae (Musci)
J. Hattori Bot. Lab. No. 76: 13- 20 (Oct. 1994) ON THE EVOLUTION AND CIRCUMSCRIPTION OF THE NECKERACEAE (MUSCI) JOHANNES ENROTH 1 ABSTRACT. The family Neckeraceae (Musci) contains the traditional subfamilies Neckeroideae and Thamnobryoideae ("Thamnioideae"). The family must be defined mainly on gametophyte characters, since the sporophytes display great plasticity. A few gametophyte characters critical in the definition of the Neckeraceae are pointed out. A list of the 23 genera provisionally accepted in the family is provided. The key word in understanding the evolution of the Neckeraceae is reduction, implying anatomical and morphological reduction in both generations. For example, the evolution of the peri stome shows a reduction series from the generalized perfect hypnoid type (e.g., Thamnobryum Nieuwl.) to various reduced "neckeroid" types (e.g., Neckera Hedw. and Neckeropsis Reichardt). Several primitive versus advanced character states in the gametophytes and sporophytes of neckera ceous mosses are briefly discussed. Hypnodendron (C. Mull.) Lindb. ex. Mitt. and Climacium Web. & Mohr. are provisionally recognized as outgroups. It is emphasized that the evolution of the two gener ations have not always progressed at same "rate", since there exist genera with a primitive gameto phyte and an advanced sporophyte, and vice versa. INTRODUCTION To understand the present-day expression of a given natural group of organisms, one must have a good comprehension of the group's evolutionary history. This paper presents, for the first time, ideas on the evolution and their bearing on the circumscription of the iso bryalian moss family Neckeraceae. The generic relationships within the Neckeraceae have not yet been cladistically scrutinized, and global revisions are wanting for some critical genera, such as Neckera Hedw., Porotrichum (Brid.) Hampe, Porotrichodendron Fleisch., and Thamnobryum Nieuwl. -

Wild Species 2015 the GENERAL STATUS of SPECIES in CANADA
Wild Species 2015 THE GENERAL STATUS OF SPECIES IN CANADA Canadian Endangered Species Conservation Council National General Status Working Group This report is a product from the collaboration of all provincial and territorial governments in Canada, and of the federal government. Canadian Endangered Species Conservation Council. 2016. Wild Species 2015: The General Status of Species in Canada. National General Status Working Group: 128 pp. Available in French under title: Espèces sauvages 2015: la situation générale des espèces au Canada. ii Abstract In this report, the conservation status of 29 848 species has been assessed in Canada among 34 different taxonomic groups: selected macrofungi, macrolichens, bryophytes, vascular plants, sponges, corals, freshwater bivalves, terrestrial and freshwater snails and slugs, spiders, mayflies, dragonflies and damselflies, stoneflies, grasshoppers and relatives, lacewings, beetles, ants, bees, yellowjacket wasps, caddisflies, moths and butterflies, scorpionflies, black flies, mosquitoes, horse flies, bee flies, flower flies, decapods, sea cucumbers, sea urchins, fishes, amphibians, reptiles, birds, and mammals. Results indicate that the majority of species in Canada are secure. In fact, among species that are critically imperiled, imperiled, vulnerable, apparently secure or secure, 80% of species have a national rank of apparently secure or secure. However, 1659 species were identified as may be at risk in Canada. Of these, 1032 species have only a small part of their range in Canada (10% or less) and 498 are intermediary (from 11% to 74%). However, 129 species have 75% or more of their range in Canada, of which 99 species are thought to be endemic to Canada. A priority score was determined for each of the 1659 species that may be at risk, and 296 species had the highest priority scores (between 1 and 5). -

Canadian Biodiversity: the IUCN Red List and SARA
Canadian Biodiversity : The IUCN Red List and SARA Bombus terricol a , photo by Tom Murray – Discover Life Debborah Donnelly University College Dublin World Heritage Conservation May 27 , 2016 D. Donnelly 1 Introduction Canadian biodiversity is extensive , and is subjected to many of the same g lobal pressures that effect all non - human species. The IUCN Red List was developed to inform and encourage governments to take action in a prioritised fashion, in order to address those species most at risk. This paper shall i dentify the differences betwee n the IUCN Red List and the Canadian Species at Risk Act (SARA) registr y with regards to Canadian taxa, as well as the major threats facing them. A spreadsheet will be included with information gleaned from both databases for conducting analysis, and in or der to c ompare and contrast the results for Canada with the IUCN list of global priorities. IUCN Red List Criteria The IUCN (2012: 14 - 15) provides definitions for the criteria following: “ Least Concern (LC) - A taxon is Least Concern when it has been evalu ated against the criteria and does not qualify for Critically Endangered, Endangered, Vulnerable or Near Threatened. Widespread and abundant taxa are included in this category. Near Threatened (NT) - A taxon is Near Threatened when it has been evaluated ag ainst the criteria but does not qualify for Critically Endangered, Endangered or Vulnerable now, but is close to qualifying for or is likely to qualify for a threatened category in the near future . Vulnerable (VU) - A taxon is Vulnerable when the best avai lable evidence indicates that it meets any of the criteria A to E for Vulnerable (see Section V), and it is therefore considered to be facing a high risk of extinction in the wild.
