Nile Crocodile (Crocodylus Niloticus) Genetic Diversity and Population Structure, Within the Lower Kunene and Okavango Rivers of Northern Namibia
Nile crocodile (Crocodylus niloticus) genetic diversity and population structure, within the lower Kunene and Okavango Rivers of northern Namibia by William F. Versfeld Thesis presented in partial fulfilment of the requirements for the degree of Master of Science in the Faculty of Natural Science at Stellenbosch University Supervisor: Dr Ruhan Slabbert Co-Supervisor: Dr Clint Rhode and Dr Alison Leslie Department of Genetics Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Date: March 2016 Copyright © 2016 Stellenbosch University All rights reserved i Stellenbosch University https://scholar.sun.ac.za Abstract The Nile crocodile has experienced numerous stages of illegal hunting pressures in the mid-20th- century across most of the species’ distribution. The reduced Nile crocodile populations have shown partial recovery and it is currently considered as a “lower risk” / “least concern” species on the Red List of International Union for Conservation of Nature. In Namibia, however, the Nile crocodile is recognised as a protected game species under the Nature Conservation Ordinance No 4 of 1975, allowing trophy hunting of the species only with the issuing of a hunting licence. Census and genetic data of the Nile crocodile is limited or non-existing in Namibia and the country has recently developed a species management plan to conserve the wild populations. -

Date: March 2016 Copyright © 2016 Stellenbosch University All rights reserved Stellenbosch University https://scholar.sun.ac.za iii GENERAL ABSTRACT Fallow deer (Dama dama), although not native to South Africa, are abundant in the country and could contribute to domestic food security and economic stability. Nonetheless, this wild ungulate remains overlooked as a protein source and no information exists on their production potential and meat quality in South Africa. The aim of this study was thus to determine the carcass characteristics, meat- and offal-yields, and the physical- and chemical-meat quality attributes of wild fallow deer harvested in South Africa. Gender was considered as a main effect when determining carcass characteristics and yields, while both gender and muscle were considered as main effects in the determination of physical and chemical meat quality attributes. Live weights, warm carcass weights and cold carcass weights were higher (p < 0.05) in male fallow deer (47.4 kg, 29.6 kg, 29.2 kg, respectively) compared with females (41.9 kg, 25.2 kg, 24.7 kg, respectively), as well as in pregnant females (47.5 kg, 28.7 kg, 28.2 kg, respectively) compared with non- pregnant females (32.5 kg, 19.7 kg, 19.3 kg, respectively). -

Human Pressure Threaten Swayne's Hartebeest to Point of Local
Research Article Volume 8:1,2020 Journal of Biodiversity and Endangered DOI: 10.24105/2332-2543.2020.8.239 Species ISSN: 2332-2543 Open Access Human Pressure Threaten Swayne’s Hartebeest to Point of Local Extinction from the Savannah Plains of Nech Sar National Park, South Rift Valley, Ethiopia Simon Shibru1*, Karen Vancampenhout2, Jozef Deckers2 and Herwig Leirs3 1Department of Biology, Arba Minch University, Arba Minch, Ethiopia 2Department of Earth and Environmental Sciences, Katholieke Universiteit Leuven, Celestijnenlaan 200E, B-3001 Leuven, Belgium 3Department of Biology, University of Antwerp, Groenenborgerlaan 171, B-2020 Antwerpen, Belgium Abstract We investigated the population size of the endemic and endangered Swayne’s Hartebeest (Alcelaphus buselaphus swaynei) in Nech Sar National Park from 2012 to 2014 and document the major threats why the species is on the verge of local extinction. The park was once known for its abundant density of Swayne’s Hartebeest. We used direct total count methods for the census. We administered semi-structured interviews and open-ended questionnaires with senior scouts who are a member of the local communities. Historical records were obtained to evaluate the population trends of the animals since 1974. The density of the animal decreased from 65 in 1974 to 1 individual per 100 km2 in 2014 with a decline of 98.5% in the past 40 years. The respondents agreed that the conservation status of the park was in its worst condition ever now with only 2 Swayne’s Hartebeest left, with a rapid decline from 4 individuals in 2012 and 12 individuals in 2009. Mainly hunting and habitat loss, but also unsuitable season of reproduction and shortage of forage as minor factors were identified as threats for the local extinction of the Swayne’s Hartebeests. -
South Africa: Magoebaskloof and Kruger National Park Custom Tour Trip Report
SOUTH AFRICA: MAGOEBASKLOOF AND KRUGER NATIONAL PARK CUSTOM TOUR TRIP REPORT 24 February – 2 March 2019 By Jason Boyce This Verreaux’s Eagle-Owl showed nicely one late afternoon, puffing up his throat and neck when calling www.birdingecotours.com [email protected] 2 | TRIP REPORT South Africa: Magoebaskloof and Kruger National Park February 2019 Overview It’s common knowledge that South Africa has very much to offer as a birding destination, and the memory of this trip echoes those sentiments. With an itinerary set in one of South Africa’s premier birding provinces, the Limpopo Province, we were getting ready for a birding extravaganza. The forests of Magoebaskloof would be our first stop, spending a day and a half in the area and targeting forest special after forest special as well as tricky range-restricted species such as Short-clawed Lark and Gurney’s Sugarbird. Afterwards we would descend the eastern escarpment and head into Kruger National Park, where we would make our way to the northern sections. These included Punda Maria, Pafuri, and the Makuleke Concession – a mouthwatering birding itinerary that was sure to deliver. A pair of Woodland Kingfishers in the fever tree forest along the Limpopo River Detailed Report Day 1, 24th February 2019 – Transfer to Magoebaskloof We set out from Johannesburg after breakfast on a clear Sunday morning. The drive to Polokwane took us just over three hours. A number of birds along the way started our trip list; these included Hadada Ibis, Yellow-billed Kite, Southern Black Flycatcher, Village Weaver, and a few brilliant European Bee-eaters. -
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. -

We explored all of these and more during our 25-day adventure across the country. Highlights were many and included Orange River Francolin, thousands of Cape Gannets, multiple Secretarybirds, stunning Knysna Turaco, Ground Woodpecker, Botha’s Lark, Bush Blackcap, Cape Parrot, Aardvark, Aardwolf, Caracal, Oribi and Giant Bullfrog, along with spectacular scenery, great food and excellent accommodation throughout. ___________________________________________________________________________________ Despite havoc-wreaking weather that delayed flights on the other side of the world, everyone managed to arrive (just!) in South Africa for the start of our keenly-awaited tour. We began our 25-day cross-country exploration with a drive along Zaagkuildrift Road. This unassuming stretch of dirt road is well-known in local birding circles and can offer up a wide range of species thanks to its variety of habitats – which include open grassland, acacia woodland, wetlands and a seasonal floodplain.

Connochaetes Gnou – Black Wildebeest
Connochaetes gnou – Black Wildebeest Blue Wildebeest (C. taurinus) (Grobler et al. 2005 and ongoing work at the University of the Free State and the National Zoological Gardens), which is most likely due to the historic bottlenecks experienced by C. gnou in the late 1800s. The evolution of a distinct southern endemic Black Wildebeest in the Pleistocene was associated with, and possibly driven by, a shift towards a more specialised kind of territorial breeding behaviour, which can only function in open habitat. Thus, the evolution of the Black Wildebeest was directly associated with the emergence of Highveld-type open grasslands in the central interior of South Africa (Ackermann et al. 2010). Andre Botha Assessment Rationale Regional Red List status (2016) Least Concern*† This is an endemic species occurring in open grasslands in the central interior of the assessment region. There are National Red List status (2004) Least Concern at least an estimated 16,260 individuals (counts Reasons for change No change conducted between 2012 and 2015) on protected areas across the Free State, Gauteng, North West, Northern Global Red List status (2008) Least Concern Cape, Eastern Cape, Mpumalanga and KwaZulu-Natal TOPS listing (NEMBA) (2007) Protected (KZN) provinces (mostly within the natural distribution range). This yields a total mature population size of 9,765– CITES listing None 11,382 (using a 60–70% mature population structure). This Endemic Yes is an underestimate as there are many more subpopulations on wildlife ranches for which comprehensive data are *Watch-list Threat †Conservation Dependent unavailable. Most subpopulations in protected areas are stable or increasing.
