Concept Reference Code: B93WIL01NAUS Name Used in Concept Reference: Lynx canadensis Taxonomic Comments: Placed in the genus Felis by some authors. Some authors regard L. lynx, L. canadensis, and L. pardinus as conspecific (see Tumlison 1987). Jones et al. (1992) treated L. canadensis and L. lynx as conspecific. Baker et al. (2003) amd Wozencraft (in Wilson and Reeder 1993, 2005) recognized L. canadensis (North America), L. lynx (Eurasia), and L. pardinus (Portugal, Spain) as separate species. Conservation Status NatureServe Status Global Status: G5 Global Status Last Reviewed: 21Feb2000 Global Status Last Changed: 19Nov1996 Rounded Global Status: G5 - Secure Reasons: Large range in northern North America; declines have occurred in some populations, but apparently still widespread and relatively abundant in most of historic range, though population data are lacking for many areas; habitat loss/fragmentation and susceptibility to overharvest are the major concerns. In the contiguous U.S., overall numbers and range are substantially reduced from historical levels. At present, numbers have not recovered from overexploitation by both regulated and unregulated harvest that occurred in the 1970s and 1980s. Forest management practices that result in the loss of diverse age structure, fragmentation, roading, urbanization, agriculture, recreational developments, and unnatural fire frequencies have altered suitable habitat in many areas. As a result, many states may have insufficient habitat quality and/or quantity to sustain lynx or their prey. Human access into habitat has increased dramatically over the last few decades contributing to direct and indirect mortality and displacement from suitable habitat. Although legal take is highly restricted, existing regulatory http://www.natureserve.org/explorer/servlet/NatureServe?sourceTemplate=tabular_report.w... 5/1/2012 Comprehensive Report Species - Lynx canadensis Page 2 of 13 mechanisms may be inadequate to protect small, remnant populations or to conserve habitat. Competition with bobcats and coyotes may be a concern in some areas. Nation: United States National Status: N4?

USFWS (Federal Register, 27 May 1997) determined that listing of the contiguous U.S. population is warranted but precluded by other higher priority actions. USFWS (Federal Register, 8 July 1998) proposed listing the U.S. lower 48 population segment as threatened. USFWS (Federal Register, 8 July 1999) extended for not more than six months a decision to list the contiguous United State population segment as a threatened species; this extension was made to allow time to resolve a dispute over the status of the U.S. lower 48 lynx population. USFWS (2000) determined threatened status for the contiguous U.S. distinct population segment of L. canadensis. USFWS (2006) designated critical habitat for the contiguous U.S. distinct population segment. In total, approximately 1.841 square miles (4,768 square kilometers) fall within the boundaries of the critical habitat designation, in three units in the States of Minnesota, Montana and Washington (Federal Register, 9 November 2006). NatureServe Global Conservation Status Factors Range Extent: >2,500,000 square km (greater than 1,000,000 square miles) Range Extent Comments: Throughout Alaska and Canada (except arctic islands) south through the Rocky Mountains, northern Great Lakes region, and northern New England. Also northern Eurasia if regarded as conspecific with LYNX LYNX (=FELIS LYNX). See U.S. Fish and Wildlife Service (1998) for information on distribution and relative abundance in the contiguous U.S. Considered historically resident in 16 states represented by five ecologically distinct regions: Cascade Range (Washington, Oregon), northern Rocky Mountains (northeastern Washington, southeastern Oregon, Idaho, Montana, western Wyoming, northern Utah), southern Rocky Mountains (southeastern Wyoming, Colorado), northern Great Lakes (Minnesota, Wisconsin, Michigan ), and northern New England (Maine, New Hampshire, Vermont, New York, Pennsylvania, Massachusetts). Resident populations currently exist only in Maine, Montana, Washington, and possibly Minnesota; considered extant but no longer sustaining self-support populations in Wisconsin, Michigan, Oregon, Idaho, Wyoming, Utah, and Colorado; may be extirpated from New Hampshire, Vermont, New York, Pennsylvania, and Massachusetts (U.S. Fish and Wildlife Service 1998). See Stardom (1988 COSEWIC report) for information on distribution and relative abundance in Canada, where still widespread and relatively abundant in most of historic range. See USFWS (2000) for a state-by-state review of historical and current distribution. Number of Occurrences: 81 to >300 Number of Occurrences Comments: Unknown, but numerous--Nearctic (or Holarctic) distribution. Population Size: 10,000 to >1,000,000 individuals Population Size Comments: Total population size is unknown, but it varies cyclically with availability of food; total probably is at least in the hundreds of thousands during population peaks, based on annual harvests in Canada that periodically exceed 50,000 (Nowak 1991). British Columbia population was estimated to vary between 200,000 and 250,000 (Goodchild and Munro 1980). See Stardom (1988 COSEWIC report) for information on status in Canada. In the contiguous U.S., total population size is unknown, but probably less than 2,000. Colorado: only 18 positive recordrds; none since 1973; proposing to reintroduce lynx (Colorado Division of Wildlife 1997). Idaho: less than 100 individuals (C. Harris, pers. comm., 1997). Maine: less than 200 individuals (C. McLaughlin, pers. comm., 1997). Oregon: perhaps fewer than 75 individuals (E. Gaines, pers. comm., 1997). Utah: very rare, few if any extant occurrences (G. Oliver, pers. comm., 1997). Montana: 740-1040 individuals (B. Giddings, pers. comm., 1998). Washington: 72-191 individuals (Washington Department of Wildlife 1993, Washington Department of Natural Resources 1996). Wyoming: less than 100 individuals (B. Oakleaf, pers. comm., 1998). Periodic increases in lynx numbers may be accentuated by dispersal of transient animals from Canadian populations (U.S. Fish and Wildlife Service 1998). It has been suggested that, because lynx occurrence throughout much of the continguous U.S. is on the southern periphery of the species' range, the presence of lynx is solely a consequence of dispersal from Canada and that most of the U.S. may never have supported self-sustaining, resident populations over time (U.S. Fish and Wildlife http://www.natureserve.org/explorer/servlet/NatureServe?sourceTemplate=tabular_report.w... 5/1/2012 Comprehensive Report Species - Lynx canadensis Page 3 of 13 Service 1998). Overall Threat Impact Comments: In determining threatened status for the contiguous U.S. distinct population segment, USFWS (2000) cited the inadequacy of existing regulatory mechanisms. "Current U.S. Forest Service Land and Resource Management Plans include programs, practices, and activities within the authority and jurisdiction of federal land management agencies that may threaten lynx or lynx habitat. The lack of protection for lynx in these plans render[s] them inadequate to protect the species" (USFWS 2000). Past extensive logging that eliminated habitat for lynx and snowshoe hare was detrimental. Habitat has been lost due to suppression of forest fires and ecological succession to

  • 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.

  • Description of the Final Stadium Larva (Odonata: Libellulidae)
    ------- Received 22 May 2003; revised and accepted 06 October 2003------- Nesciothemis farinosa: description of the final stadium larva (Odonata: Libellulidae) Frank Suhling', Carsten Schutte' & Ole Muller' ' lnstitut fUr Geookologie, Technische Universitat Braunschweig, Langer Kamp 19c, D-381 02 Braunschweig, Germany. <e-mail [email protected]> ' Birkenweg 6d, D-15306 Libbenichen, Germany. Key words: Odonata, dragonfly, Nesciothemis farinosa, larval description, notes on ecology and development. ABSTRACT A written description and illustrations of the final stadium larva of Nesciothemis farinosa are presented, based on larvae and exuviae collected in Namibia. The larvae were reared in the laboratory until emergence. Additionally, information on larval microhabitat, behaviour and development is provided. INTRODUCTION The genus Nesciothemis Longfield, 1955 is composed of five species, N. farinosa (Forster, 1898), N. fitzgeraldi Longfield, 1955, N. minor Gambles, 1966, N. nigeriensis Gambles, 1966 and N. pujoli Pinhey, 1971 (Gambles 1966; Pinhey 1971; Dijkstra 2003) occurring in subsaharan continental Africa, Egypt and the southern Arabian Peninsula, with N. farinosa being the most widespread species, ranging from southern Africa to Egypt and Arabia (Dumont 1991; Schneider & Krupp 1993; Carfl & D'Andrea 1994; Samways 1999; Clausnitzer 2001). N. farinosa reported from western Africa (e.g. Ivory Coast, Tsuda 1991) are questionable, because they differ constantly from typical N. farinosa and might belong to N. pujoli (K.-D.B. Dijkstra in litt.). The larvae of all Nesciothemis species are hitherto not described. Here we describe the final stadium larva and exuvia of N. farinosa from material collected in Namibia. Additionally, information on the larval microhabitat, behaviour in the laboratory and develop­ ment is provided.

    International Journal ofOdonatology 4 (2): 93-105,2001 © 2001 Backhuys Publishers. 93 Description of the larva of Somatochlora hineana with a key to the larvae of the North American species of Somatochlora (Odonata: Corduliidae) Everett D. Cashatt & Timothy E. Vogt Zoology Section, Illinois State Museum Research and Collection Center, 1011 East Ash, Springfield, IL 62703 <cashatt@ museum. state.il. us> Received 06 March 200 I ; revised and accepted 28 April 200 I. Key words: Odonata, dragonfly, Somatochlora hineana, larva, description, key, North America. Abstract A detailed description of the final stadium of Somatochlora hineana, with brief notes on the penultimate stadium, is presented. An illustration of the entire larva and separate line drawings of the labium and dorsal and lateral views of the abdomen are also included. The habitat of the larva is discussed briefly. Combinations of diagnostic characters are used for distinguishing the S. hineana larva from its allied congeners. A key to the known Somatochlora larvae of North American species is given. Introduction Somatochlora hineana was described by Williamson (1931) from a series of adults from Logan Co., Ohio, USA. Subsequently, this species has been documented from the following states and counties: Alabama: Jackson; Illinois: Cook, DuPage, Will; Indiana: Lake; Michigan: Alpena, Mackinac, Presque Isle; Missouri: Reynolds; Ohio: Lucus, Williams; and Wisconsin: Door, Ozaukee (U.S. Fish and Wildlife Service in prep). Recent attempts to confirm the presence of this species in Alabama, Indiana, and Ohio have been unsuccessful. Habitat and behavior were discussed briefly by Vogt & Cashatt (1994). It was listed as Endangered by the United States Fish and Wildlife Service in 1995 (Federal Register 60# [ 17]: 5267 -5272) because of its narrow ecological requirements and vulnerability to habitat degradation and destruction.

  • ARTHROPODA Subphylum Hexapoda Protura, Springtails, Diplura, and Insects
    NINE Phylum ARTHROPODA SUBPHYLUM HEXAPODA Protura, springtails, Diplura, and insects ROD P. MACFARLANE, PETER A. MADDISON, IAN G. ANDREW, JOCELYN A. BERRY, PETER M. JOHNS, ROBERT J. B.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

May And approved by _____________________________________ _____________________________________ _____________________________________ _____________________________________ New Brunswick, New Jersey January, 2016 ABSTRACT OF THE DISSERTATION THE LIFE HISTORY, BEHAVIOR AND CONSERVATION OF THE TIGER SPIKETAIL DRAGONFLY (CORDULEGASTER ERRONEA HAGEN) IN NEW JERSEY by DAVID PAUL MOSKOWITZ Dissertation Director: Dr. Michael L. May This dissertation explores the life history and behavior of the Tiger Spiketail dragonfly (Cordulegaster erronea Hagen) and provides recommendations for the conservation of the species. Like most species in the genus Cordulegaster and the family Cordulegastridae, the Tiger Spiketail is geographically restricted, patchily distributed with its range, and a habitat specialist in habitats susceptible to disturbance. Most Cordulegastridae species are also of conservation concern and the Tiger Spiketail is no exception. However, many aspects of the life history of the Tiger Spiketail and many other Cordulegastridae are poorly understood, complicating conservation strategies. In this dissertation, I report the results of my research on the Tiger Spiketail in New Jersey. The research to investigate life history and behavior included: larval and exuvial sampling; radio- telemetry studies; marking-resighting studies; habitat analyses; observations of ovipositing females and patrolling males, and the presentation of models and insects to patrolling males.
