  • Communities of Small Mammals in Kafue National Park and Their Response to Fire, Vegetation and Land Use
    Communities of small mammals in Kafue National Park and their response to fire, vegetation and land use DISSERTATION submitted for the degree of Doctor of Science (Dr. rer. nat.) Department of Animal Ecology and Conservation University of Hamburg Photo taken by: Neeta Simunji submitted by Ngawo Namukonde Hamburg, 2017 i Revised version Dissertation reviewers: Prof. Dr. Jörg U Ganzhorn Prof. Dr. Japhet K Mbata Date of oral defense: 24th November, 2017 ii Summary Small mammals assume multiple and cardinal roles in ecosystem functionality. They are known to influence the composition and structure of plant communities through their herbivorous and seed predation activities, as agents of soil aeration through their burrowing activities, pest controllers as the consume large amounts of insects and plant material, and as food for a variety of prey. Yet, the understanding of small mammal ecology is overshadowed by studies of large mammals as small mammals have very little tourism appeal and are often viewed as vermin benefiting from human disturbances. Even so, many small mammals are known to be highly sensitive to anthropogenic factors. This lack of information on small mammals also applies to the Kafue National Park (KNP), Zambia, including the Busanga Flood Plain as one of KNP’s critical habitats and a wetland of international importance (RAMSAR site number 1659). Not much is known about small mammals in the KNP, much less the influence of anthropogenic and non-antropogenic factors on their communities. Given that KNP is a protected area where the human foot print is minimized, anthropogenic factors that act upon the communities of small mammals include bush fires, that occur repeatedly (annually) on wildlands.

Cherry Co-supervisor: Dr. Lynda L. Sharpe March 2017 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. Janneke Rubow, March 2017 Copyright © 2017 Stellenbosch University All rights reserved Stellenbosch University https://scholar.sun.ac.za Abstract Vocal communication is important in social vertebrates, particularly those for whom dense vegetation obscures visual signals. Vocal signals often convey secondary information to facilitate rapid and appropriate responses. This function is vital in long-distance communication. The long-distance recruitment vocalisations of dwarf mongooses (Helogale parvula) provide an ideal opportunity to study informative cues in acoustic communication. This study examined the information conveyed by two recruitment calls given in snake encounter and isolation contexts, and whether dwarf mongooses are able to respond differently on the basis of these cues. Vocalisations were collected opportunistically from four wild groups of dwarf mongooses. The acoustic parameters of recruitment calls were then analysed for distinction between contexts within recruitment calls in general, distinction within isolation calls between groups, sexes and individuals, and the individuality of recruitment calls in comparison to dwarf mongoose contact calls.

  • Benefits-Of-Regulated-Hunting-For-Leopard
    CONSERVATION FORCE A FORCE FOR WILDLIFE CONSERVATION BENEFITS OF REGULATED HUNTING FOR LEOPARD (PANTHERA PARDUS) Legal, regulated tourist hunting of African leopard (Panthera pardus) benefits the species through mitigation of the primary threats: habitat loss and fragmentation; increased human populations leading to higher incidence of human-wildlife conflict; poaching and illegal wildlife trade; and prey base declines.i • Habitat: The threat of habitat loss is mitigated in part by fully-protected national parks, which provide over 400,000 km2 of relatively secure habitat for leopard across the six Southern African Development Community (SADC) countries that rely on regulated hunting to sustain their leopard and leopard prey populations.ii The national parks are > 30,000 km2 larger than in 1982, when the leopard was downlisted to “threatened” under the U.S. Endangered Species Act, and leopard are estimated to be present in most of the parks in Mozambique, Namibia, Tanzania, Zambia, and Zimbabwe.iii Regulated hunting revenues help cover the costs of policing these parks, which in most cases do not generate sufficient revenue to cover all enforcement expenses.iv • Habitat: The threat of habitat loss is further mitigated by areas dedicated to regulated hunting. In Mozambique, Tanzania, Zambia, and Zimbabwe, hunting areas include government reserves, communal wildlife management areas, and private ranches. They are substantially larger than the national parks and represent over 700,000 km2.v Leopard are estimated to be present across almost all hunting areas.vi • Habitat: According to the 2016 IUCN Red List assessment of leopard, the species’ total extant range exceeds 8.5 million km2, with between 4.3 million and 6.3 million km2 of range available in Southern and East Africa.

  • Big Cats in Africa Factsheet
    INFORMATION BRIEF BIG CATS IN AFRICA AFRICAN LION (PANTHERA LEO) Famously known as the king of the jungle, the African lion is the second largest living species of the big cats, after the tiger. African lions are found mostly in savannah grasslands across many parts of sub-Saharan Africa but the “Babary lion” used to exist in the North of Africa including Tunisia, Morocco and Algeria, while the “Cape lion” existed in South Africa. Some lions have however been known to live in forests in Congo, Gabon or Ethiopia. Historically, lions used to live in the Mediterranean and the Middle East as well as in other parts of Asia such as India. While there are still some Asian Lions left in India, the African Lion is probably the largest remaining sub species of Lions in the world. They live in large groups called “prides”, usually made up of up to 15 lions. These prides consist of one or two males, and the rest females. The females are known for hunting for prey ranging from wildebeest, giraffe, impala, zebra, buffalo, rhinos, hippos, among others. The males are unique in appearance with the conspicuous mane around their necks. The mane is used for protection and intimidation during fights. Lions mate all year round, and the female gives birth to three or four cubs at a time, after a gestation period of close to 4 months (110 days). Lions are mainly threatened by hunting and persecution by humans. They are considered a threat to livestock, so ranchers usually shoot them or poison carcasses to keep them away from their livestock.

  • Panthera Pardus) and Its Extinct Eurasian Populations Johanna L
    Paijmans et al. BMC Evolutionary Biology (2018) 18:156 https://doi.org/10.1186/s12862-018-1268-0 RESEARCH ARTICLE Open Access Historical biogeography of the leopard (Panthera pardus) and its extinct Eurasian populations Johanna L. A. Paijmans1* , Axel Barlow1, Daniel W. Förster2, Kirstin Henneberger1, Matthias Meyer3, Birgit Nickel3, Doris Nagel4, Rasmus Worsøe Havmøller5, Gennady F. Baryshnikov6, Ulrich Joger7, Wilfried Rosendahl8 and Michael Hofreiter1 Abstract Background: Resolving the historical biogeography of the leopard (Panthera pardus) is a complex issue, because patterns inferred from fossils and from molecular data lack congruence. Fossil evidence supports an African origin, and suggests that leopards were already present in Eurasia during the Early Pleistocene. Analysis of DNA sequences however, suggests a more recent, Middle Pleistocene shared ancestry of Asian and African leopards. These contrasting patterns led researchers to propose a two-stage hypothesis of leopard dispersal out of Africa: an initial Early Pleistocene colonisation of Asia and a subsequent replacement by a second colonisation wave during the Middle Pleistocene. The status of Late Pleistocene European leopards within this scenario is unclear: were these populations remnants of the first dispersal, or do the last surviving European leopards share more recent ancestry with their African counterparts? Results: In this study, we generate and analyse mitogenome sequences from historical samples that span the entire modern leopard distribution, as well as from Late Pleistocene remains. We find a deep bifurcation between African and Eurasian mitochondrial lineages (~ 710 Ka), with the European ancient samples as sister to all Asian lineages (~ 483 Ka). The modern and historical mainland Asian lineages share a relatively recent common ancestor (~ 122 Ka), and we find one Javan sample nested within these.

  • The 2008 IUCN Red Listings of the World's Small Carnivores
    The 2008 IUCN red listings of the world’s small carnivores Jan SCHIPPER¹*, Michael HOFFMANN¹, J. W. DUCKWORTH² and James CONROY³ Abstract The global conservation status of all the world’s mammals was assessed for the 2008 IUCN Red List. Of the 165 species of small carni- vores recognised during the process, two are Extinct (EX), one is Critically Endangered (CR), ten are Endangered (EN), 22 Vulnerable (VU), ten Near Threatened (NT), 15 Data Deficient (DD) and 105 Least Concern. Thus, 22% of the species for which a category was assigned other than DD were assessed as threatened (i.e. CR, EN or VU), as against 25% for mammals as a whole. Among otters, seven (58%) of the 12 species for which a category was assigned were identified as threatened. This reflects their attachment to rivers and other waterbodies, and heavy trade-driven hunting. The IUCN Red List species accounts are living documents to be updated annually, and further information to refine listings is welcome.
