I. Morphology and Histochemistry ROBERT D. ROMANOWSKI, DONALD E. THOMPSON, AND PHILIP A. MADDEN National Animal Parasite Laboratory, Veterinary Sciences Research Division, ARS, USDA, Beltsville, Maryland 20705. ABSTRACT: Morphological, histochemical, and ultrastructural studies show that the excretory gland cells of Stephanurus dentatus contain granules resembling the secretory granules of various exocrine and endo- crine glands. The granules are eosin and PAS positive. Glycogen, acid mucopolysaccharides, and lipids were not detected histochemically. Therefore, the granules are thought to contain glycoprotein. From this evidence it is postulated that the excretory gland cells have a secretoiy function.

  • Disaggregation of Bird Families Listed on Cms Appendix Ii
    Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

  • Assessment and Conservation of Threatened Bird Species at Laojunshan, Sichuan, China
    CLP Report Assessment and conservation of threatened bird species at Laojunshan, Sichuan, China Submitted by Jie Wang Institute of Zoology, Chinese Academy of Sciences, Beijing, P.R.China E-mail:[email protected] To Conservation Leadership Programme, UK Contents 1. Summary 2. Study area 3. Avian fauna and conservation status of threatened bird species 4. Habitat analysis 5. Ecological assessment and community education 6. Outputs 7. Main references 8. Acknowledgements 1. Summary Laojunshan Nature Reserve is located at Yibin city, Sichuan province, south China. It belongs to eastern part of Liangshan mountains and is among the twenty-five hotspots of global biodiversity conservation. The local virgin alpine subtropical deciduous forests are abundant, which are actually rare at the same latitudes and harbor a tremendous diversity of plant and animal species. It is listed as a Global 200 ecoregion (WWF), an Important Bird Area (No. CN205), and an Endemic Bird Area (No. D14) (Stattersfield, et al . 1998). However, as a nature reserve newly built in 1999, it is only county-level and has no financial support from the central government. Especially, it is quite lack of scientific research, for example, the avifauna still remains unexplored except for some observations from bird watchers. Furthermore, the local community is extremely poor and facing modern development pressures, unmanaged human activities might seriously disturb the local ecosystem. We conducted our project from April to June 2007, funded by Conservation Leadership Programme. Two fieldwork strategies were used: “En bloc-Assessment” to produce an avifauna census and ecological assessments; "Special Survey" to assess the conservation status of some threatened endemic bird species.

  • The Generic Taxonomy of Parrotbills (Aves, Timaliidae)
    FORKTAIL 25 (2009): 137–141 The generic taxonomy of parrotbills (Aves, Timaliidae) JOHN PENHALLURICK and CRAIG ROBSON The parrotbills are typically considered to contain just three genera: Conostoma, Paradoxornis and Panurus. Discounting Panurus from consideration (it has recently been shown to have a distant relationship to the babblers), we maintain a single species in Conostoma, C. aemodium, and assign the species currently lumped into Paradoxornis among seven genera that fall into two groups based in part on size: the first group (which also includes Conostoma) consists of Hemirhynchus (for paradoxus and unicolor); Psittiparus (for gularis, margaritae, ruficeps and bakeri) and Paradoxornis (for flavirostris, guttaticollis and heudei); the second comprises Chleuasicus (for atrosuperciliaris), a new genus Sinosuthora (for brunnea, webbiana, alphonsiana, conspicillata, zappeyi and przewalskii), Neosuthora (for davidiana) and Suthora (for fulvifrons, verreauxi, nipalensis, humii, poliotis, ripponi and beaulieui). INTRODUCTION to reflect this distant relationship. We will go through the genera we propose, giving the full citation for the generic Earlier accounts of the parrotbills, such as Sharpe (1883), name, plus synonyms, and listing the species we assign to Hartert (1907), Hartert and Steinbacher (1932–38), and each genus, and its subspecies, with detailed distribution Baker (1930), treated them in multiple genera, but in provided for both monotypic species and subspecies. recent works (Deignan 1964, Dickinson 2003, Robson 2007) the great majority have been placed in Paradoxornis. This arrangement goes back to Delacour (1946), who THE GENERA AND SPECIES assigned all taxa except Great Parrotbill Conostoma aemodium and Bearded Reedling Panurus biarmicus to Conostoma Hodgson, 1842 Paradoxornis. His explanation for this radical move was Conostoma Hodgson, 1842 [‘1841’], Journal of the Asiatic brief, and roughly translates as follows: Society of Bengal 10: 856.

CROIX RIVER DRAINAGE FINAL REPORT Submitted to: Lee Ann Pfannmuller Nongame Wildlife Program Minnesota Department of Natural Resources Box 7, 500 Lafayette Road St. Paul, Minnesota 55146 Submitted by: Jay T. Hatch, Ph.D. Division of Science, Business, and Mathematics General College University of Minnesota 216 Pillsbury Dr. SE Minneapolis, MN 55455 February 24, 1986 Introduction One of the most abundant and ubiquitous groups of nongame fishes found in Minnesota is the darter group (Percidae: Etheostomatini). These lively and colorful fishes inhabit nearly all of our streams and rivers and many of our lakes (Eddy and Underhill, 1974). We know in general that darters play an important role in the trophic structure of stream ecosystems (Cummins 1980), and we know that some species are important indicators of general water quality (Gerking 1945; Smith 1971; Pflieger 1975; Burr 1980; Karr 1981). Yet, we know very little about the specific life histories of the darters of our state, and we know even less about how their resource utilization patterns change with changes in habitat and community structure. To date, only three life history studies have been cared out on Minnesota darter populations. Erickson (1977) studied the banded darter (Etheostoma zonale) in the Cannon River; Coon (1982) studied several aspects of the comparative ecology of the rainbow (E. coeruleum), fantail (E. flabellare) and Johnny (E. nigrum) darters in the Root River; and Hatch (1982, 1986) studied the gilt darter (Percina evides) in the St.
