  • Friday Night Auction
    GETTING YOUTH OUTDOORS Welcome Dear Friends and Fellow Outdoor Supporters, Welcome and thank you for supporting the second annual Heartland DSC Banquet! Heartland DSC is excited to state that during the last year we were able to successfully pursue our mission of “Getting Youth Outdoors” by exposing kids to hunting and fishing that may have not otherwise had the opportunity. Highlights of the past year included a youth fishing tournament, certification of new young hunters during our hunter education course, a youth shooting clinic and Heartland DSC sponsored youth hunts. For many of the young participants it was their first time doing these types of activities. We took a large step in providing hunting opportunities for young people by securing exclusive access to a tract of land teaming with deer and turkey. This provides us the ability to offer youth hunting in a well-controlled environment. While our efforts are focused on all youth, we are putting a special emphasis on introducing outdoor activities to those youth that may not otherwise have the opportunity due to disabilities, lack of accessibility, or other life circumstances. We have worked hard to attract outstanding auction items from reputable outfitters and donors who have graciously donated to the organization’s mission. Heartland DSC encourages you to place your bids with confidence and in the spirit of providing the funds necessary to further the organization’s objectives while obtaining goods and services for your enjoyment. Again, thank you for your support and have a wonderful evening!

  • Reproductive Seasonality in Captive Wild Ruminants: Implications for Biogeographical Adaptation, Photoperiodic Control, and Life History
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2012 Reproductive seasonality in captive wild ruminants: implications for biogeographical adaptation, photoperiodic control, and life history Zerbe, Philipp Abstract: Zur quantitativen Beschreibung der Reproduktionsmuster wurden Daten von 110 Wildwiederkäuer- arten aus Zoos der gemässigten Zone verwendet (dabei wurde die Anzahl Tage, an denen 80% aller Geburten stattfanden, als Geburtenpeak-Breite [BPB] definiert). Diese Muster wurden mit verschiede- nen biologischen Charakteristika verknüpft und mit denen von freilebenden Tieren verglichen. Der Bre- itengrad des natürlichen Verbreitungsgebietes korreliert stark mit dem in Menschenobhut beobachteten BPB. Nur 11% der Spezies wechselten ihr reproduktives Muster zwischen Wildnis und Gefangenschaft, wobei für saisonale Spezies die errechnete Tageslichtlänge zum Zeitpunkt der Konzeption für freilebende und in Menschenobhut gehaltene Populationen gleich war. Reproduktive Saisonalität erklärt zusätzliche Varianzen im Verhältnis von Körpergewicht und Tragzeit, wobei saisonalere Spezies für ihr Körpergewicht eine kürzere Tragzeit aufweisen. Rückschliessend ist festzuhalten, dass Photoperiodik, speziell die abso- lute Tageslichtlänge, genetisch fixierter Auslöser für die Fortpflanzung ist, und dass die Plastizität der Tragzeit unterstützend auf die erfolgreiche Verbreitung der Wiederkäuer in höheren Breitengraden wirkte. A dataset on 110 wild ruminant species kept in captivity in temperate-zone zoos was used to describe their reproductive patterns quantitatively (determining the birth peak breadth BPB as the number of days in which 80% of all births occur); then this pattern was linked to various biological characteristics, and compared with free-ranging animals. Globally, latitude of natural origin highly correlates with BPB observed in captivity, with species being more seasonal originating from higher latitudes.

The deer was treated with enrofloxacin (5 mg/kg) and ivermectin (0.2 mg/kg) with no response. The animal underwent two surgical procedures to remove purulent material and perform adequate antisepsis as well as several antimicrobial therapies, with satisfactory results in a period of 68 days.

Universidade Federal de Pernambuco, 55608-680 Vitoria de Santo Antao — PE, Brazil Abstract The small red brocket deer Mazama bororo is one of the most endangered deer in the Neotropics. The great morphological similarities with three other sympatric brocket deer species, coupled with the fact that they inhabit densely forested habitats complicate detection and prevent the use of traditional methodologies for accurate identification of species. The ability to determine the presence of this endangered species in an area is crucial for estimating its distribution range, and is critical for establishing conservation management strategies. Here we describe a fast and reliable noninvasive genetic method for species identification of Mazama species from faeces.

ABSTRACT. Neotropical deer species have broad geographic ranges in vulnerable Latin American ecosystems. Habitat destruction and overhunting have limited deer species to a portion of their historical ranges. Our aims are to provide an overview of the current state of knowledge of Neotropical deer species systematics and evo- lutionary history, and to discuss their current conservation status.

  • Gallina & Mandujano
    Mongabay.com Open Access Journal - Tropical Conservation Science Vol. 2 (2):116-127, 2009 Special issue: introduction Research on ecology, conservation and management of wild ungulates in Mexico Sonia Gallina1 and Salvador Mandujano1 1 Departamento de Biodiversidad y Ecología Animal, Instituto de Ecología A. C., km. 2.5 Carret. Ant. Coatepec No. 351, Congregación del Haya, Xalapa 91070, Ver. México. E‐mail: <[email protected]>; <[email protected]> Abstract This special issue of Tropical Conservation Science provides a synopsis of nine of the eleven presentations on ungulates presented at the Symposium on Ecology and Conservation of Ungulates in Mexico during the Mexican Congress of Ecology held in November 2008 in Merida, Yucatan. Of the eleven species of wild ungulates in Mexico (Baird´s tapir Tapirus bairdii, pronghorn antelope Antilocapra americana, American bison Bison bison, bighorn sheep Ovis canadensis, elk Cervus canadensis, red brocket deer Mazama temama, Yucatan brown brocket Mazama pandora, mule deer Odocoileus hemionus, white-tailed deer Odocoileus virginianus, white-lipped peccary Tayassu pecari and collared peccary Pecari tajacu), studies which concern four of these species are presented: Baird’s tapir and the white lipped peccary, which are tropical species in danger of extinction; the bighorn sheep, of high value for hunting in the north-west; and the white-tailed deer, the most studied ungulate in Mexico due to its wide distribution in the country and high hunting and cultural value. In addition, two studies of exotic species, wild boar (Sus scrofa) and red deer (Cervus elaphus), are presented. Issues addressed in these studies are: population estimates, habitat use, evaluation of UMA (Spanish acronym for ‘Wildlife Conservation, Management and Sustainable Utilization Units’) and ANP (Spanish acronym for ‘Natural Protected Areas’) to sustain minimum viable populations, and the effect of alien species in protected areas and UMA, all of which allow an insight into ungulate conservation and management within the country.
