RSG Book Template 2011 V4 051211 IUCN IUCN, International Union for Conservation of Nature, helps the world find pragmatic solutions to our most pressing environment and development challenges. IUCN works on biodiversity, climate change, energy, human livelihoods and greening the world economy by supporting scientific research, managing field projects all over the world, and bringing governments, NGOs, the UN and companies together to develop policy, laws and best practice. IUCN is the world’s oldest and largest global environmental organization, with more than 1,200 government and NGO members and almost 11,000 volunteer experts in some 160 countries. IUCN’s work is supported by over 1,000 staff in 60 offices and hundreds of partners in public, NGO and private sectors around the world. IUCN Species Survival Commission (SSC) The SSC is a science-based network of close to 8,000 volunteer experts from almost every country of the world, all working together towards achieving the vision of, “A world that values and conserves present levels of biodiversity.” Environment Agency - ABU DHABI (EAD) The EAD was established in 1996 to preserve Abu Dhabi’s natural heritage, protect our future, and raise awareness about environmental issues. EAD is Abu Dhabi’s environmental regulator and advises the government on environmental policy. It works to create sustainable communities, and protect and conserve wildlife and natural resources. EAD also works to ensure integrated and sustainable water resources management, and to ensure clean air and minimize climate change and its impacts. Denver Zoological Foundation (DZF) The DZF is a non-profit organization whose mission is to “secure a better world for animals through human understanding.” DZF oversees Denver Zoo and conducts conservation education and biological conservation programs at the zoo, in the greater Denver area, and worldwide. Over 3,800 animals representing more than 650 species call Denver Zoo home. A member of the World Association of Zoos and Aquariums (WAZA), Denver Zoo’s accreditation from the Association of Zoos and Aquariums (AZA) assures the highest standards of animal care. A leader in environmental action, Denver Zoo was the first U.S. zoo to receive ISO 14001 sustainability certification for its entire facility and operations and in 2011 was voted the greenest zoo in the country. The ISO 14001 international certification ensures the zoo attains the highest environmental standards. Since 1994, Denver Zoo has participated in well over 550 conservation projects in 55 countries. In 2011 alone, Denver Zoo participated in 70 projects in 20 countries and spent well over US$ 1 million to support wildlife conservation in the field. Re-introduction Specialist Group (RSG) The RSG is a network of specialists whose aim is to combat the ongoing and massive loss of biodiversity by using re-introductions as a responsible tool for the management and restoration of biodiversity. It does this by actively developing and promoting sound inter-disciplinary scientific information, policy, and practice to establish viable wild populations in their natural habitats. i ii The designation of geographical entities in this book, and the presentation of the material, do not imply the expression of any opinion whatsoever on the part of IUCN or any of the funding organizations concerning the legal status of any country, territory, or area, or of its authorities, or concerning the delimitation of its frontiers or boundaries.

  • Fisheries Across the Eastern Continental Divide
    Fisheries Across the Eastern Continental Divide Abstracts for oral presentations and posters, 2010 Spring Meeting of the Southern Division of the American Fisheries Society Asheville, NC 1 Contributed Paper Oral Presentation Potential for trophic competition between introduced spotted bass and native shoal bass in the Flint River Sammons, S.M.*, Auburn University. Largemouth bass, shoal bass, and spotted bass were collected from six sites over four seasons on the Flint River, Georgia to assess food habits. Diets of all three species was very broad; 10 categories of invertebrates and 15 species of fish were identified from diets. Since few large spotted bass were collected, all comparisons among species were conducted only for juvenile fish (< 200 mm) and subadult fish (200-300 mm). Juvenile largemouth bass diets were dominated by fish in all seasons, mainly sunfish. Juvenile largemouth bass rarely ate insects except in spring, when all three species consumed large numbers of insects. In contrast, juvenile shoal bass diets were dominated by insects in all seasons but winter. Juvenile spotted bass diets were more varied- highly piscivorous in the fall and winter and highly insectivorous in spring and summer. Diets of subadult largemouth bass were similar to that of juvenile fish, and heavily dominated by fish, particularly sunfish. Similar to juveniles, diets of subadult shoal bass were much less piscivorous than largemouth bass. Crayfish were important components of subadult shoal bass diets in all seasons but summer. Insects were important components of shoal bass diets in fall and summer. Diets of subadult spotted bass were generally more piscivorous than shoal bass, but less than largemouth bass.

  • Petition to List the Relict Leopard Frog (Rana Onca) As an Endangered Species Under the Endangered Species Act
    BEFORE THE SECRETARY OF INTERIOR PETITION TO LIST THE RELICT LEOPARD FROG (RANA ONCA) AS AN ENDANGERED SPECIES UNDER THE ENDANGERED SPECIES ACT CENTER FOR BIOLOGICAL DIVERSITY SOUTHERN UTAH WILDERNESS ALLIANCE PETITIONERS May 8, 2002 EXECUTIVE SUMMARY The relict leopard frog (Rana onca) has the dubious distinction of being one of the first North American amphibians thought to have become extinct. Although known to have inhabited at least 64 separate locations, the last historical collections of the species were in the 1950s and this frog was only recently rediscovered at 8 (of the original 64) locations in the early 1990s. This extremely endangered amphibian is now restricted to only 6 localities (a 91% reduction from the original 64 locations) in two disjunct areas within the Lake Mead National Recreation Area in Nevada. The relict leopard frog historically occurred in springs, seeps, and wetlands within the Virgin, Muddy, and Colorado River drainages, in Utah, Nevada, and Arizona. The Vegas Valley leopard frog, which once inhabited springs in the Las Vegas, Nevada area (and is probably now extinct), may eventually prove to be synonymous with R. onca. Relict leopard frogs were recently discovered in eight springs in the early 1990s near Lake Mead and along the Virgin River. The species has subsequently disappeared from two of these localities. Only about 500 to 1,000 adult frogs remain in the population and none of the extant locations are secure from anthropomorphic events, thus putting the species at an almost guaranteed risk of extinction. The relict leopard frog has likely been extirpated from Utah, Arizona, and from the Muddy River drainage in Nevada, and persists in only 9% of its known historical range.

  • Transmission Rates of the B Chromosome of Myrmeleote7tix Maculatus (Orthoptera: Acrididae) M
    Heredity (1984), 53 (2), 259—268 1984. The Genetical Society of Great Britain THEEFFECT OF TEMPERATURE ON MEIOTIC TRANSMISSION RATES OF THE B CHROMOSOME OF MYRMELEOTE7TIX MACULATUS (ORTHOPTERA: ACRIDIDAE) M. W. SHAW* AND G. M. HEWIU School of Biological Sciences, University of East Anglia, Norwich NR3 7 TJ, U. K. Received19.xii.83 SUMMARY Meiotic drive of B-chromosomes in Myrmeleotettix maculatus females decreased slightly during the course of egg-laying but was not detectably different under different temperature regimes. A proportion of males, however, showed substan- tially reduced transmission of the B chromosome when maintained at lower temperatures. This could explain some of the geographic variation in B chromo- some frequency that has been observed. 1. INTRODUCTION The B chromosome polymorphism of the heathiand grasshopper Myr- meleotettix maculatus is restricted to the southern and central parts of the U.K., although the animal itself is much more widespread (e.g., Hewitt and John, 1967). This restricted range may be due in part to historical and geographical accidents—there is evidence that in at least one part of the boundary of the B chromosome distribution the B may still be spreading (Shaw, 1983). However, it is also likely that the equilibrium B frequency varies from place to place. For example, Hewitt and Ruscoe (1971) examined both microclimatic variables and B frequency in a series of populations along a 1 km transect in the Welsh hills near Aberystwyth. It was clear that where the microclimate was cooler, the B frequency was lower. This suggests that the B might be restricted to the southern U.K.

  • 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.

Loppnow IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Advised by Paul A. Venturelli February 2017 © Grace L. Loppnow 2017 Acknowledgements “Nobody achieves anything alone.” -Leslie Knope, Parks and Recreation That is certainly true of this dissertation, which would not have been possible without the collaboration and support of many. First, a huge thank you to my advisor, Paul Venturelli. From our first meeting onward, you have gone out of your way to make grad school an enjoyable experience. Thank you for building me into a scientist, and for always encouraging me to grow. Thanks especially for knowing when to push me and when to let me hole up in “the writing cave.” When I was choosing an advisor 6 years ago, someone warned me that joining a new lab might be difficult. I found it to be quite the opposite. I’ve enjoyed growing with you, and have benefitted from your mentorship right from the start. Most of all, thank you for always having a sense of humor. Google will never be the same… Special thanks to my advisory committee: Bruce Vondracek, Ray Newman, Don Pereira, Tom Hrabik, and a guest appearance by Przemek Bajer. Your insights and willingness to help have been of great assistance. Thanks also to the fellow students who accompanied me on this journey. I’d like to acknowledge the support and fellowship of my “academic brothers and sisters,” my labmates: Kyle Chezik, Jason Papenfuss, Fernanda Cabrini Araujo, Cha Thao, Andrew Honsey, Megan Tomamichel, Leslie Schroeder, Tim Martin, Nate Huempfner, Natnael i Hamda, and Manu Garcia.

Biodiversity Data Journal 2: e1093. doi: 10.3897/BDJ.2.e1093 Abstract The potential fish species pool of the Kubo, Tochikura, and Ichinono river systems (tributaries of the Iwai River, Kitakami River drainage), Iwate Prefecture, northern Japan, was compared with the observed ichthyofauna by using historical records and new field surveys. Based on the literature survey, the potential species pool comprised 24 species/ subspecies but only 20, including 7 non-native taxa, were recorded during the fieldwork. The absence during the survey of 11 species/subspecies from the potential species pool suggested either that sampling effort was insufficient, or that accurate determination of the potential species pool was hindered by lack of biogeographic data and ecological data related to the habitat use of the species. With respect to freshwater fish conservation in the area, Lethenteron reissneri, Carassius auratus buergeri, Pseudorasbora pumila, Tachysurus tokiensis, Oryzias latipes, and Cottus nozawae are regarded as priority species, and Cyprinus rubrofuscus, Pseudorasbora parva, and Micropterus salmoides as targets for removal.

Rivers in the Japanese archipelago, separated from the continent of Asia by about 17 Ma, have experienced an intermittent exchange of freshwater fish taxa through a narrow land bridge generated by lowered sea level. As the Korean Peninsula and Japanese archipelago were not covered by an ice sheet during glacial periods, phylogeographical analyses in this region can trace the history of biota that were, for a long time, beyond the last glacial maximum. In this study, we analyzed the phylogeography of four freshwater fish taxa, Hemibarbus longirostris, dark chub Nipponocypris temminckii, Tanakia ssp. and Carassius ssp., whose distributions include both the Korean Peninsula and Western Japan. We found for each taxon that a small component of diverse Korean clades of freshwater fishes Citation: Taniguchi, S.; Bertl, J.; migrated in waves into the Japanese archipelago to form the current phylogeographic structure of Futschik, A.; Kishino, H.; Okazaki, T.
