Chromosomal Evolution in Raphicerus Antelope Suggests Divergent X
www.nature.com/scientificreports OPEN Chromosomal evolution in Raphicerus antelope suggests divergent X chromosomes may drive speciation through females, rather than males, contrary to Haldane’s rule Terence J. Robinson1*, Halina Cernohorska2, Svatava Kubickova2, Miluse Vozdova2, Petra Musilova2 & Aurora Ruiz‑Herrera3,4 Chromosome structural change has long been considered important in the evolution of post‑zygotic reproductive isolation. The premise that karyotypic variation can serve as a possible barrier to gene fow is founded on the expectation that heterozygotes for structurally distinct chromosomal forms would be partially sterile (negatively heterotic) or show reduced recombination. We report the outcome of a detailed comparative molecular cytogenetic study of three antelope species, genus Raphicerus, that have undergone a rapid radiation. The species are largely conserved with respect to their euchromatic regions but the X chromosomes, in marked contrast, show distinct patterns of heterochromatic amplifcation and localization of repeats that have occurred independently in each lineage. We argue a novel hypothesis that postulates that the expansion of heterochromatic blocks in the homogametic sex can, with certain conditions, contribute to post‑ zygotic isolation. i.e., female hybrid incompatibility, the converse of Haldane’s rule. This is based on the expectation that hybrids incur a selective disadvantage due to impaired meiosis resulting from the meiotic checkpoint network’s surveillance of the asymmetric expansions of heterochromatic blocks in the homogametic sex. Asynapsis of these heterochromatic regions would result in meiotic silencing of unsynapsed chromatin and, if this persists, germline apoptosis and female infertility. Te chromosomal speciation theory 1,2 also referred to as the “Hybrid dysfunction model”3, has been one of the most intriguing questions in biology for decades. -

Gaits and Their Development in the Infraorder Pecora by Anne Innis
Gaits and Their Development in the Infraorder Pecora by Anne Innis Dagg, M.A. THESIS Presented to the Faculty of Graduate Studies of the University of Waterloo in partial ful fillmenc of the requirements for the degree of Doctor of Philosopty in Biolog The University of Waterloo February, 1967 The University of Waterloo requires the signature of all persons using this thesis. Please sign below, and give address and date. I hereby declare that I am the sole a�thor of this thesis. I authorize the University of Waterloo to lend it to other institutions or individuals for the purpose of scholarly research. Signature Abstract The gaits of twenty-eight species of the Infraorder Pecora are analyzed from motion picture sequences comprising over 45,000 frames. For each gait the percentage time spent on the various supporting legs during each stride and the order in which the combinations of supporting legs were used are tabulated. When possible the times for the strides are calculated. The walk patterns of each of the four families studied are shown to be statistically distinctive. Within each family, those members that live where the vegetation is so dense that they must rely on hearing to warn them of danger use a more stable walk than those species that inhabit open grasslands. A stable walk is that in which diagonal legs are used in·preference to lateral legs and three or four supporting legs are used rather than two. With a more stable walk, 4 species is able to pause quickly and to flee instantly if danger thr�atens. -
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. -

Box 32379, Lusaka, Zambia; 4Kavango Transfrontier Wild Animal, Gaborone, Botswana Abstract: Babesia spp. were detected from 4 asymptomatic pukus captured on a game ranch in central Zambia in Octo- ber 2008. Blood smears were examined in 4 species of aymptomatic free-ranging antelopes, namely the puku (Kobus vor danii), reedbuck (Redunca arundinum), bushbuck (Tragelaphus sylvaticus), and kudu (Tragelaphus strepsiceros), and showed the presence of Babesia parasites only in the puku. In the puku, the prevalence of babesiosis was estimated at 33.3% (n=12), while the overall prevalence in all examined animals was 8.5% (n=47). The parasites showed morphologi- cal characteristics of paired ring-like stages with the length varying between 1.61 µm and 3.02 µm (mean=2.12 µm, n= 27; SD=0.76 µm). Both the infected and non-infected pukus showed good body condition scores (BCS), while the domi- nant tick species detected from all animals were Rhipicephalus appendiculatus, Rhipicephalus spp., and Boophilus spp. -

Implications for the Conservation of Key Species in the Udzungwa Mountains, Tanzania
Genetic Patterns in Forest Antelope Populations: Implications for the Conservation of Key Species in the Udzungwa Mountains, Tanzania Submitted by Andrew Edward Bowkett, to the University of Exeter as a thesis for the degree of Doctor of Philosophy in Biological Sciences In September 2012 This thesis is available for Library use on the understanding that it is copyright material and that no quotation from the thesis may be published without proper acknowledgement. I certify that all material in this thesis which is not my own work has been identified and that no material has previously been submitted and approved for the award of a degree by this or any other University. Signature: ………………………………………………………….. ABSTRACT The field of conservation genetics, in combination with non-invasive sampling, provides a powerful set of tools for investigating the conservation status and natural history of rare species that are otherwise difficult to study. A systematic literature review demonstrated that this is certainly the case for many forest- associated antelope species, which are poorly studied and yet constitute some of the most heavily hunted wildlife in Africa. The aim of the present study was to use non-invasive sampling to investigate genetic patterns in forest antelope populations in the high-biodiversity Udzungwa Mountains, Tanzania, within the context of the conservation of these species and the wider ecosystem. Genetic information was derived from faecal samples collected across the Udzungwa landscape and assigned to five antelope species (N = 618, collected 2006-09). Faecal pellet length was measured for a subset of samples but statistical assignment to species by this method proved unreliable. -

On the Use of the IUCN Status for the Management of Trophy Hunting
CSIRO PUBLISHING Wildlife Research, 2012, 39, 711–720 http://dx.doi.org/10.1071/WR12121 On the use of the IUCN status for the management of trophy hunting Lucille Palazy A,B,C, Christophe Bonenfant A, Jean-Michel Gaillard A and Franck Courchamp B ALaboratoire Biométrie et Biologie Évolutive, UMR CNRS 5558, University Claude Bernard Lyon 1, 43 boulevard du 11 novembre 1918, 69622 Villeurbanne Cedex, France. BLaboratoire Écologie, Systématique et Evolution, UMR CNRS 8079, University Paris Sud, 91405 Orsay Cedex, France. CCorresponding author. Email: [email protected] Abstract Context. Whether trophy hunting is beneficial or a threat to the conservation of species is an open and hotly debated question. The International Union for Conservation of Nature (IUCN) is in charge of assessing the need for species protection at the global scale and providing a useful guide for sustainable exploitation and conservation. Consideration of the IUCN status in wildlife management and its consequences on the attractiveness of trophy-hunted species remains to be quantified. Aims. The present study investigated the link between the IUCN status of the trophy species and its exploitation in 124 taxa. We expected that the number of trophies should be inversely correlated with the IUCN vulnerability status across species. Methods. Using the database of the Safari Club International, one of the largest hunting associations worldwide, we investigated the effect (1) of the first status attribution and (2) of an upgrade of the IUCN status on the number of trophies recorded by the Safari Club International, by comparing the average number of trophies 5 years before and after a status change. -
