Wylie and James W. Bates.. ............................................................79 Editor's Note Readers of this year's Transactions will note that major papers precede Progress Reports, a reverse order from that in prior Transactions. Several considerations necessitate this change. Some persons outside the DBC have been unaware that our published papers (but not Progress Reports) undergo peer review. Peer review has been used for a number of years, but has not been reflected in the limited number of names listed under the Editorial Committee. Major con- tributors, but not necessarily all participants, to the editorial process have been listed. In academic institutions and some agencies, publications are regarded as fundamenral evidence of a professional's productivity. In such instances, only papers published in reputable, refereed journals are given credence. Some persons have presented excellent papers at the annual meeting, but have declined to publish their results in the Transactions because their Department Chairman or supervisor considered the Transactions to be a non- refereed journal. In reality, our review process is equivalent to that of a number of well known journals having larger audiences. The inclusion of Progress Reports is unusual in scientific journals, but is not unique to the DBC Transactions. The archaeological journal, American Antiquity, contains a section on Cur- rent Research, which summarizes projects by regions of the country. Owing to the long term nature of bighorn studies, timely dissemination of new information by means of Progress Reports often can aid other workers and save them substantial time. Earlierprocedures of plac- ing non-reviewed Progress Reports in the front of the Transactions also may have helped pro- mote misconceptions. I have therefore clearly separated reviewed papers from non-reviewed Progress Reports. I also have taken the liberty of judging whether a manuscript is a paper or a progress report, although some authors may not concur with my choices. If the review process is working, it should lead to rejection of manuscripts that contain no the content and aesthetic qualities of the Transactions. It is my hope that our peer review pro- cess will continue to elevate the quality of papers appearing in the Transactions while being fair snd sensitive to all concernea. DESERT BIGHORN COUNCIL 1979 TRANSACTIONS -1- more than 20 million years ago during the Early Miocene Age THE EVOLUTION, [Figure 11. However, it appears that the first true sheep, or members of the genus Ovis, did not appear until about 2.5 SYSTEMATICS, AND million years ago during the Early Pleistocene or 'Glacial' Epoch, which also is synonymous with the Late Pliocene [Flint CYTOGENETICS OF OVlS 19711. The fossil record of Ovis is fragmentary, and concrete data J. Juan Spillett relating to its mode of evolution are scanty. Thus, there is con- Uinta National Forest siderable debate and much speculation as to the evolution and Provo, Utah taxonomic relationships of Ovis. Some authorities speculate Thomas D. Bunch that true sheep originated from Rupicaprini or goat-antelopes International Sheep and Goat Institute [Thenius and Hofer 19601; whereas, others believe that Ovis Department of Animal, Dairy, and Veterinary Sciences originated from Aoudad or Barbary sheep [Ammotragus] or an Utah State University Ammotragus-like ancestor [Geist 1971, Bunch et al. 19761. Logan, Utah 84322 There also is considerable speculation and confusion as to the Abstract. True sheep [Ovis] originated somewhere in south- relationship of Ovis to the following Rupicaprids: 11Chamois central Asia during the Pleistocene Epoch approximately 2.5 [Rupicapra rupicapra], which inhabits the Alps, Apennines and million years ago and were dispersed throughout most of the Carpathians to the Caucasus Mountains in Asia Minor, and mountainous areas in the northern hemisphere, primarily as a the Pyrenes and Cantabrian Mountains of Spain; 21 Gorals result of geographical events such as glaciation. That, in turn, [Nemorhaedus goral], which inhabit the Himalayan Mountains resulted in considerable diversification in Ovis and in the fact east through West China and North Korea; 31 Serows that today wild sheep still have a distribution unequalled by [Capricornis sumatraensis and C. crispus], which are found any living bovid [Geist 19711. from Sumatra and the Malayan Peninsula north through Viet- nam, Thailand, Burma, Assam, the eastern Himalayas and True sheep are included in the Subfamily Caprinae, which is China, and on the islands of Formosa; and 41 The so-called further divided into four tribes [Saigini, Rupicaprini, Ovibovini, Rocky Mountain

  • Field Guide to the Sandia Mountains, Edited by Robert Julyan & Mary
    Volume 45 Issue 4 Fall 2005 Fall 2005 Field Guide to the Sandia Mountains, edited by Robert Julyan & Mary Stuever Nancy Harbert Recommended Citation Nancy Harbert, Field Guide to the Sandia Mountains, edited by Robert Julyan & Mary Stuever, 45 Nat.

For more information, please contact [email protected], [email protected], [email protected]. 1120 NATURAL RESOURCES JOURNAL [Vol. 45 Field Guide to the Sandia Mountains. Edited by Robert Julyan & Mary Stuever: Albuquerque: University of New Mexico Press, 2005. Pp. 255. $19.95 spiral-bound paperback. This easy-to-absorb handbook does not pretend to be an exhaustive manual to the Sandia Mountains. Early on, editor Robert Julyan, who is best known for his book The Place Names of New Mexico, makes it clear that the intention among the guide's many contributors is to provide an introduction to the various elements that combine to make up the Sandia Mountains, a compact mountain range that provides the eastern backdrop for Albuquerque. With hundreds of plants and animals, not to mention microbes and soil types, Julyan points out that it would be impossible to represent them all in a guidebook. Therefore, the book focuses on the species and features that visitors are most likely to encounter. Because of the range's proximity to Albuquerque, a city of nearly 500,000 people, it is probably trampled on more than any other mountains in the state.

The age assigned to the Kinney Brick Quarry (early-middle Virgilian) has long been based more on its inferred lithostratigraphic position than on biostratigraphic indicators at the quarry. We have developed three datasets —-stratigraphic position, fusulinids and conodonts— that in- dicate the Kinney Brick Quarry is older, of middle Missourian (Kasimovian) age.

Email: [email protected] "Member, Rocky Mountain Outdoor Writers and Photographers, 1330 West Gold Street, Butte, MT 59701. Email: [email protected] Using repeatable protocols, a survey ofArgali sheep (Ovis nnimon) in Mongolia was conducted across their range during November 2002. A country-wide population of 20,226 was estimated. Approximately 7% of Mongolia's 34,873 sq. km Agali range was surveyed. This was Mongolia's first repeatable survey for monitoring purposes. Other population estimates have been made, but the survey protocols were not given, making them unrepeatable and unusable for monitoring population trend. Population trend was established for a number of specific survey sites by comparing data collected during this survey with those done earlier in which the protocols were described. Population levels in some areas were depressed while in other areas population trend was stable or increasing. If the Mongolian Government implements a country-wide and site-specific Argali sustainable use management plan, potentially between 202-404 trophy rams could be harvested annually.

    EURASIAN MIDDLE AND LATE MIOCENE HOMINOID PALEOBIOGEOGRAPHY AND THE GEOGRAPHIC ORIGINS OF THE HOMININAE by Mariam C. Nargolwalla A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Graduate Department of Anthropology University of Toronto © Copyright by M. Nargolwalla (2009) Eurasian Middle and Late Miocene Hominoid Paleobiogeography and the Geographic Origins of the Homininae Mariam C. Nargolwalla Doctor of Philosophy Department of Anthropology University of Toronto 2009 Abstract The origin and diversification of great apes and humans is among the most researched and debated series of events in the evolutionary history of the Primates. A fundamental part of understanding these events involves reconstructing paleoenvironmental and paleogeographic patterns in the Eurasian Miocene; a time period and geographic expanse rich in evidence of lineage origins and dispersals of numerous mammalian lineages, including apes. Traditionally, the geographic origin of the African ape and human lineage is considered to have occurred in Africa, however, an alternative hypothesis favouring a Eurasian origin has been proposed. This hypothesis suggests that that after an initial dispersal from Africa to Eurasia at ~17Ma and subsequent radiation from Spain to China, fossil apes disperse back to Africa at least once and found the African ape and human lineage in the late Miocene. The purpose of this study is to test the Eurasian origin hypothesis through the analysis of spatial and temporal patterns of distribution, in situ evolution, interprovincial and intercontinental dispersals of Eurasian terrestrial mammals in response to environmental factors. Using the NOW and Paleobiology databases, together with data collected through survey and excavation of middle and late Miocene vertebrate localities in Hungary and Romania, taphonomic bias and sampling completeness of Eurasian faunas are assessed.

    Mojave National Preserve National Park Service U.S. Department of the Interior Sweeney Granite Mountains Desert Research Center Science Newsletter Updates on respiratory disease affecting desert bighorn sheep in and near Mojave National Preserve 1 1 Clinton W. Epps , Daniella Dekelaita , and Brian Dugovich2 Desert bighorn sheep (Ovis canadensis nelsoni) are an iconic mammal of the desert southwest and are found in small mountain ranges scattered across Mojave National Preserve (Preserve) and nearby desert habitats in southeastern California. In many areas, they are the only large native herbivore that can persist, inhabiting places that are too hot, dry, and sparsely vegetated for deer. California is thought to be home to ~3000-5000 desert bighorn in total (1); desert bighorn sheep are uniquely adapted for the harsh environment of the southwest deserts and populations appear to be resilient in spite of threats from poaching, climate change, drought, and habitat fragmentation (2, 3). In the Mojave Desert, bighorn sheep populations are strongly fragmented by expanses of flat desert between Figure 1. Map of Mojave National Preserve and nearby areas in southeastern California, mountain ranges, and in some cases, by showing mountain ranges (white polygons) where respiratory disease of bighorn sheep is being studied using GPS collars, remote cameras, disease screening of captured animals, behavioral and physical barriers such as fecal DNA, immunological and genetic measures, and other methods.

  • REPORT on TRANSBOUNDARY CONSERVATION HOTSPOTS for the CENTRAL ASIAN MAMMALS INITIATIVE (Prepared by the Secretariat)
    CONVENTION ON UNEP/CMS/COP13/Inf.27 MIGRATORY 8 January 2020 SPECIES Original: English 13th MEETING OF THE CONFERENCE OF THE PARTIES Gandhinagar, India, 17 - 22 February 2020 Agenda Item 26.3 REPORT ON TRANSBOUNDARY CONSERVATION HOTSPOTS FOR THE CENTRAL ASIAN MAMMALS INITIATIVE (Prepared by the Secretariat) Summary: This report was developed with funding from the Government of Switzerland within the frame of the Central Asian Mammals Initiative (CAMI) (Doc. 26.3.5) to identify transboundary conservation hotspots and develop recommendations for their conservation. The report builds on existing projects, in particular, the CAMI Linear Infrastructure and Migration Atlas (see Inf.Doc.19) and focusses on the same species and geographical area. The study was discussed during the CAMI Range State Meeting held from 25-28 September 2019 in Ulaanbaatar, Mongolia where participants reviewed the pre-identified areas. Their comments are incorporated in this report. Participants also provided new information about important transboundary sites from Bhutan, India, Nepal and Pakistan and recommended to send the report for final review to Range States and experts. It was also recommended that the final report covers all CAMI species as adopted at COP13. This report is therefore a final draft with the last step to expand the geographical and species scope and finalize the report to be undertaken after COP13. Mapping Transboundary Conservation Hotspots for the Central Asian Mammals Initiative Photo credit: Viktor Lukarevsky Report – Draft 5 incorporating comments made during the CAMI Range States Meeting on 25-28 September 2019 in Ulaanbaatar, Mongolia. The report does not yet consider the Urial, Persian leopard and Gobi bear as CAMI species pending decision at the CMS COP13, as well as the proposed expansion of the geographic and species scope to include the entire CAMI region in this study.
