INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated w ith a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced. 5. PLEASE NOTE: Some pages may have indistinct print. Filmed as received.

    Endangered Species

    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

  • Master List of Fishes

    Master List of Fishes

    FISHES OF THE FRESHWATER POTOMAC Compiled by Jim Cummins, The Interstate Commission on the Potomac River Basin Always DRAFT - Version 02/21/2013 The following list of one-hundred and eighteen fish species known to be present in the freshwater portions of the Potomac River basin. Included, but not numbered, are fish that once were in the Potomac but are no longer are present; eight extirpated fish species (only one of which, the log perch, was perhaps a native to the Potomac) and three with uncertain presences. The list was originally (1995) compiled through a combination of personal field experience, a search of the literature, and input from regional fisheries biologists Ed Enamait (MD), Gerald Lewis (WV), Ed Stienkoenig (VA), and Jon Siemiens (DC). However, I attempt to keep the list updated when new information becomes available, thus the list is always draft. The distribution of these fishes within the Potomac is highly variable. Many are year-round residents and are fairly wide-spread, while some, such as the torrent shiner, are only found in very limited habitats/areas. Eleven are migratory species which typically come into the river system to spawn, and nine represent occasional visitors in freshwater-tidal areas. The native or introduced status of most of these species are generally accepted, but for some species this status is an object of continued researched and therefore caution should be used in interpreting this designation, especially when noted with a “?” mark. Of the 118 species currently found in the river, approximately 80 (68%) are considered native, 23 (19%) are considered introduced, and the rest (15, or 13%) are uncertain in origin.

ZooKeys 874: 31–45. https://doi.org/10.3897/zookeys.874.35618 Abstract Species checklists and dichotomous keys are valuable tools that provide many services for ecological stud- ies and management through tracking native and non-native species through time. We developed nine drainage basin checklists and dichotomous keys for 196 inland fishes of Texas, consisting of 171 native fishes and 25 non-native fishes. Our checklists were updated from previous checklists and revised using reports of new established native and non-native fishes in Texas, reports of new fish occurrences among drainages, and changes in species taxonomic nomenclature. We provided the first dichotomous keys for major drainage basins in Texas. Among the 171 native inland fishes, 6 species are considered extinct or extirpated, 13 species are listed as threatened or endangered by U.S. Fish and Wildlife Service, and 59 spe- cies are listed as Species of Greatest Conservation Need (SGCN) by the state of Texas.

Olivero Sheldon. 2011 Resilient Sites for Species Conservation in the Northeast and Mid-Atlantic Region. The Nature Conservancy, Eastern Conservation Science. 122pp. This project was supported by a grant to the Northeast Association of Fish and Wildlife Agencies (#2008-03 Regional Focal Areas for Species of Greatest Conservation Need based on Site Adaptive Capacity, Network Resilience and Connectivity) and through funding from the Doris Duke Charitable Foundation and The Nature Conservancy. The work was made possible by data and contributions from the network of Natural Heritage Programs and NatureServe. Project Summary: Resilience concerns the ability of a living system to adjust to climate change, to moderate potential damages, to take advantage of opportunities, or to cope with consequences, in short: its capacity to adapt (IPCC 2007). In this project, we aimed to identify the most resilient examples of key geophysical settings (sand plains, granitic mountains, limestone valleys, etc.), in relation to species of greatest conservation need, to provide conservationists with a nuanced picture of the places where conservation is most likely to succeed under climate change. The central idea was that by mapping key geophysical settings and evaluating them for landscape characteristics that buffer against climate effects, we could identify the most resilient examples of each setting.
  • THREATENED and ENDANGERED SPECIES of NEW MEXICO 2008 Biennial Review and Recommendations

    THREATENED and ENDANGERED SPECIES of NEW MEXICO 2008 Biennial Review and Recommendations

    THREATENED AND ENDANGERED SPECIES OF NEW MEXICO 2008 BIENNIAL REVIEW DRAFT First Public Comment Period March 11, 2008 New Mexico Department of Game and Fish Conservation Services Division DRAFT 2008 Biennial Review of T & E Species of NM, 3/11/08 THREATENED AND ENDANGERED SPECIES OF NEW MEXICO 2008 Biennial Review and Recommendations Authority: Wildlife Conservation Act (17-2-37 through 17-2-46 NMSA 1978) EXECUTIVE SUMMARY: A total of 118 species and subspecies are on the 2008 list of threatened and endangered New Mexico wildlife. The list includes 2 crustaceans, 25 mollusks, 23 fishes, 6 amphibians, 15 reptiles, 32 birds and 15 mammals (Tables 1, 2). An additional 7 species of mammals has been listed as restricted to facilitate control of traffic in federally protected species. A species is endangered if it is in jeopardy of extinction or extirpation from the state; a species is threatened if it is likely to become endangered within the foreseeable future throughout all or a significant portion of its range in New Mexico. Species or subspecies of mammals, birds, reptiles, amphibians, fishes, mollusks, and crustaceans native to New Mexico may be listed as threatened or endangered under the Wildlife Conservation Act (WCA). During the Biennial Review, species may be upgraded from threatened to endangered, or downgraded from endangered to threatened, based upon data, views, and information regarding the biological and ecological status of the species. Investigations for new listings or removals from the list (delistings) can be undertaken at any time, but require additional procedures from those for the Biennial Review. The 2006 Biennial Review contained a recommendation for maintaining the status for 119 species and subspecies listed as threatened, endangered, or restricted under the WCA, and uplisting four species (Arizona grasshopper sparrow, Pecos bluntnose shiner, spikedace, and meadow jumping mouse ) from threatened to endangered and downlisting two species (shortneck snaggletooth and piping plover) from endangered to threatened.
