A National Park in Northern Rhodesia 15
A National Park in Northern Rhodesia 15 A NATIONAL PARK IN NORTHERN RHODESIA By a Proclamation dated 20th April, 1950, the Governor of Northern Rhodesia has established a National Park, to be known as the Kafue National Park. This new park covers some 8,650 square miles roughly in the central Kafue basin, between latitudes 14° and 16° 40' S. It contains a wide range of country from the comparatively drv sandy lands of the south to the big rivers, swamps, and heavy timber of the northern section. The magnificent Kafue River dominates the whole central portion, adding scenic beauty to the attraction of wild life. The park contains representatives of most species of the fauna of Northern Rhodesia. Primates are represented by the Rhodesian Baboon, the Vervet Monkey, and the Greater and Lesser Night-Apes. There are Elephant and Black Rhinoceros, Buffalo, Lion, Leopard, Cheetah, and numbers of the smaller carnivora. Antelope include Eland, Sable, Roan, Liehtenstein's Hartebeest, Blue Wildebeest, Kudu, Defassa Waterbuck, Bushbuck, Reedbuck, Puku, Impala, Oribi, Common, Blue, and Yellow-backed Duikers, Klipspringer, and Sharpe's Stein- buck. There are Red Lechwe and Sitatunga in the Busango Swamp in the north, Hippopotamus in numbers in the Kafue and its larger tributaries. Zebra are common, Warthog and Bushpig everywhere. Birds are abundant. The park is uninhabited apart from certain small settle- ments, on a limited section of the Kafue River, belonging to the indigenous Africans under their tribal chief Kayingu. These people must be accorded their traditional local hunting rights, but such will affect only a small fraction of the whole vast wild area. -
Enclosure Size in Captive Wild Mammals. a Comparison Between UK Zoological Collections
1 ENCLOSURE SIZE IN CAPTIVE WILD MAMMALS: A comparison between UK zoological collections and the wild. JORDI CASAMITJANA1 Abstract A comparison was made between the average enclosure size of a random sample of mammals kept during the years 2000- 2001 in a random sample of UK zoological collections and the minimum home range of these taxa in the wild. Allometric laws were used to estimate the home range area, while direct observation from videotaped visits to the collections was used to estimate enclosure size area. The results showed that, as an average, the average enclosure size had an area 100 times smaller than the minimum home range. Key words: mammal, zoo, enclosure size, allometric, megafauna, captivity, home range Introduction The zoo debate Nowadays, many people choose not to go to zoos because they consider that either it is wrong to keep wild animals in captivity as a matter of principle, or the conditions the animals are kept in zoos are unacceptable. The zoo community, and its supporters, think otherwise, and this difference of opinion is what constitute the so called ‘zoo debate’. It is not unusual that people engaged in such debate try to prove their points either by quoting ‘expert’ opinion or by referring to facts, evidence and reports about zoo’s activities. However, many of these ‘facts’ are missing because no objective research has ever been developed to find them. One of the most common arguments used in the zoo debate refers to the space available to captive animals kept in zoos. The anti-zoo side of the debate often criticises enclosures for being too small, while zoo advocates tend to respond that they are big enough, or that size ‘does not matter’. -

This study aims to develop a processed product from warthog meat in the form of back bacon (Longissimus thoracis et lumborum) as a healthy alternative meat product and to determine its chemical and sensory characteristics derived from adult and juvenile boars and sows. The highest scored attributes included typical bacon and smoky aroma and flavor, and salty flavor, as well as tenderness and juiciness. Neither sex nor age influenced the bacon’s chemical composition; the bacon was high in protein (~29%) and low in total fat (<2%). Palmitic (C16:0), stearic (C18:0), linoleic (C18:2!6), oleic (C18:1!9c), and arachidonic (C20:4!6) were the dominant fatty acids. There was an interaction between sex and age for the PUFA:SFA ratio (p = 0.01). -
The Naked Mole-Rat As an Animal Model in Biomedical Research: Current Perspectives
Open Access Animal Physiology Dovepress open access to scientific and medical research Open Access Full Text Article REVIEW The naked mole-rat as an animal model in biomedical research: current perspectives Laura-Nadine Schuhmacher Abstract: The naked mole-rat (NMR) is a subterranean rodent that has gained significant Zoé Husson attention from the biomedical research community in recent years as molecular mechanisms Ewan St. John Smith underlying its unusual biology start to be unraveled. With very low external mortality, NMRs have an unusually long lifespan while showing no signs of aging, such as neuro- Department of Pharmacology, University of Cambridge, Cambridge, UK degeneration or cancer. Furthermore, living underground in large colonies (100 to 300 animals), results in comparatively high carbon dioxide and low oxygen levels, from which NMRs have evolved extreme resistance to both hypoxia and hypercapnia. In this paper we have summarized the latest developments in NMR research and its impact on biomedical research, with the aim of providing a sound background that will inform and inspire further For personal use only. investigations. Keywords: naked mole-rat, longevity, cancer, hypoxia, nociception, pain Introduction The naked mole-rat (NMR) (Heterocephalus glaber) is a subterranean mammal, which has recently gained interest from scientists across a variety of research fields. Unlike the majority of mammals, NMRs are poikilothermic and eusocial, ie, are cold-blooded and have a single breeding female within a colony.1 In addition to these features, which have limited biomedical translatability, NMRs have also evolved several physiological adaptations to habituate to their extreme environmental conditions, which have led researchers to study this mammal with the hypothesis Open Access Animal Physiology downloaded from https://www.dovepress.com/ by 131.111.184.102 on 07-Sep-2017 that by understanding the extreme biology of NMRs, more will be understood about normal mammalian physiology. -
