In 2006, Alpha Wildlife Resarch & Management Ltd. published a field guide for BC Timber Sales (BCTS), Kootenay Business Area to assist planners and field crews in recognizing species and plant communities at risk in their operating areas (Proulx and Bernier 2006a). Recently, BCTS decided to update this field guide. This report is an addendum to Proulx and Bernier’s (2006a) field guide. 1.1 Selection of Species and Communities at Risk for this Report Species and plant communities at risk that were included in this report belonged to at least one of the following categories (see Proulx and Bernier 2006 for definitions): • COSEWIC – endangered, threatened or species of concern. • IWMS (Identified Wildlife Management Strategy). • CDC red- and blue- listed animals, red-listed plants, and red-listed plant communities. A total of 45 SAR were selected for this project (Table 1): 29 invertebrates, 1 amphibians/reptiles, 10 birds, 4 mammals, 0 plants, and 1 plant community. As in Proulx and Bernier (2006a), fish species at risk were not considered for this report 1.2 Accounts The development of the accounts took into consideration RISC standard for species accounts (RISC 1999). The format of this document was further modified using Proulx and Bernier’s (2006b) template. The accounts were developed in the context of an identification guide to help foresters to identify species and plant communities. The accounts therefore focused on a description of the species/plant communities and the sites where they may be found. The accounts were written using information from scientific publications, general field guides, and the CDC website. The quality and quantity of information varied significantly among accounts. While complete information is usually available for vertebrates, little is known about invertebrates at risk (particularly freshwater mollusks). In some cases, we had to use poor-quality photographs or drawings to describe invertebrates.

  • A Reconnaissance of Population Genetic Variation in Arctic and Subarctic Sulfur Butterflies (Colias Spp.; Lepidoptera, Pieridae)
    1614 A reconnaissance of population genetic variation in arctic and subarctic sulfur butterflies (Colias spp.; Lepidoptera, Pieridae) Christopher W. Wheat, Ward B. Watt, and Christian L. Boutwell Abstract: Genotype–phenotype–environment interactions in temperate-zone species of Colias Fabricius, 1807 have been well studied in evolutionary terms. Arctic and alpine habitats present a different range of ecological, especially thermal, conditions under which such work could be extended across species and higher clades. To this end, we survey variation in three genes that code for phosphoglucose isomerase (PGI), phosphoglucomutase (PGM), and glucose-6-phosphate dehydrogenase (G6PD) in seven arctic and alpine Colias taxa (one only for G6PD). These genes are highly polymor- phic in all taxa studied. Patterns of variation for the PGI gene in these northern taxa suggest that the balancing selec- tion seen at this gene in temperate-zone taxa may extend throughout northern North America. Comparative study of these taxa may thus give insight into the mechanisms driving genetic differentiation among subspecies, species, and broader clades, supporting the study of both micro- and macro-evolutionary questions. Résumé : L’étude des interactions génotype–phénotype–environnement chez les papillons Colias Fabricius, 1807 de la région tempérée s’est faite dans une perspective évolutive. Les habitats arctiques et alpins offrent une gamme différente de conditions écologiques et, en particulier, thermiques dans lesquelles un tel travail peut s’étendre au niveau des espè- ces et des clades supérieurs. Dans ce but, nous avons étudié la variation de trois gènes — ceux de la phosphoglucose isomérase (PGI), de la phosphoglucomutase (PGM) et de la glucose-6-phosphate déshydrogénase (G6PD) — chez sept taxons de Colias arctiques et alpins (un seul taxon pour G6PD).

  • Appendix A: Common and Scientific Names for Fish and Wildlife Species Found in Idaho
    APPENDIX A: COMMON AND SCIENTIFIC NAMES FOR FISH AND WILDLIFE SPECIES FOUND IN IDAHO. How to Read the Lists. Within these lists, species are listed phylogenetically by class. In cases where phylogeny is incompletely understood, taxonomic units are arranged alphabetically. Listed below are definitions for interpreting NatureServe conservation status ranks (GRanks and SRanks). These ranks reflect an assessment of the condition of the species rangewide (GRank) and statewide (SRank). Rangewide ranks are assigned by NatureServe and statewide ranks are assigned by the Idaho Conservation Data Center. GX or SX Presumed extinct or extirpated: not located despite intensive searches and virtually no likelihood of rediscovery. GH or SH Possibly extinct or extirpated (historical): historically occurred, but may be rediscovered. Its presence may not have been verified in the past 20–40 years. A species could become SH without such a 20–40 year delay if the only known occurrences in the state were destroyed or if it had been extensively and unsuccessfully looked for. The SH rank is reserved for species for which some effort has been made to relocate occurrences, rather than simply using this status for all elements not known from verified extant occurrences. G1 or S1 Critically imperiled: at high risk because of extreme rarity (often 5 or fewer occurrences), rapidly declining numbers, or other factors that make it particularly vulnerable to rangewide extinction or extirpation. G2 or S2 Imperiled: at risk because of restricted range, few populations (often 20 or fewer), rapidly declining numbers, or other factors that make it vulnerable to rangewide extinction or extirpation. G3 or S3 Vulnerable: at moderate risk because of restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors that make it vulnerable to rangewide extinction or extirpation.

Mead (1852-1936) visited central Colorado from June to September 1871 to collect butterflies. Considerable effort has been spent trying to determine the identities of the butterflies he collected for his future father-in-law William Henry Edwards, and where he collected them. Brown (1956) tried to deduce his itinerary based on the specimens and the few letters etc. available to him then. Brown (1964-1987) designated lectotypes and neotypes for the names of the butterflies that William Henry Edwards described, including 24 based on Mead’s specimens. Brown & Brown (1996) published many later-discovered letters written by Mead describing his travels and collections. Calhoun (2013) purchased Mead’s journal and published Mead’s brief journal descriptions of his collecting efforts and his travels by stage and horseback and walking, and Calhoun commented on some of the butterflies he collected (especially lectotypes). Calhoun (2015a) published an abbreviated summary of Mead’s travels using those improved locations from the journal etc., and detailed the type localities of some of the butterflies named from Mead specimens.
