CHARISMATIC PREDATORS IN MODERN AFRICA: SPOTTED HYENA (CROCUTA CROCUTA) AND HUMAN COEXISTENCE IN THE NORTHERN TULI GAME RESERVE, BOTSWANA By Jazmin Castillo A THESIS Presented to the Faculty of The Graduate College at the University of Nebraska In Partial Fulfillment of the Requirements For the Degree of Master of Science Major: Natural Resource Sciences Under the Supervision of Professors John P. Carroll and John P. DeLong Lincoln, Nebraska May, 2020 CHARISMATIC PREDATORS IN MODERN AFRICA: SPOTTED HYENA (CROCUTA CROCUTA) AND HUMAN COEXISTENCE IN THE NORTHERN TULI GAME RESERVE, BOTSWANA Jazmin Castillo, M.S. University of Nebraska, 2020 Advisors: John P. Carroll and John P. DeLong Increasing human populations has led researchers to investigate the impacts of high human population density and its impact on carnivore populations. Spotted hyenas (Crocuta crocuta) hold a unique place in African ecosystems due to being a very successful top predator with an adaptable diet whereas other top predators, like the African lion, are rapidly decreasing in abundance. We investigated past and current spotted hyena abundance within the Northern Tuli Game Reserve to better aid in wildlife management. Spotted hyenas showed no significant difference in the change in population abundance throughout the different years of the study (2008-2016). Spotted hyena populations also showed no preference in habitat types between river and upland sites whereas brown hyenas had greater detections in river sites. Spotted hyena distribution was negatively impacted by villages and proximity to the border and positively impacted by ecotourism camps and cattle posts. With the decline in riverine habitat and humans influencing wildlife space usage, it is important to further investigate whether certain areas within the reserve require different management zones for a better balance in a limited space surrounded by various human infrastructure. i DEDICATION Les dedico este proyecto a ustedes quienes dejaron todo atrás para dar me una buena vida y oportunidad.

  • Resource Partitioning Between Black-Backed Jackal and Brown Hyaena in Waterberg Biosphere Reserve, South Africa

Email: [email protected] * Correspondence author Keywords: apex predators, dietary niche, human modification, resource partitioning. Abstract Understanding resource partitioning by predators is important for understanding coexistence patterns, with this becoming more relevant as historical food webs are altered through human impacts. Using scat analysis, we investigated the diet overlap of two sympatric meso-carnviores, the black-backed jackal Canis mesomelas and brown hyaena Hyaena brunnea, in Waterberg Biosphere Reserve, South Africa. Scats (n = 30 jackal, 42 brown hyaena) were collected in April 2012 from game and livestock farms. When comparing main prey categories (medium-large mam- mal, small mammal, fruit, invertebrate, reptile, and bird) we found little difference in diets, with both carnivores con- suming predominantly medium-large mammals (10-100kg). Bushbuck Tragelaphus scriptus was the most commonly consumed large mammal species for both predators. Jackal and brown hyaena had, on average, 1.3 and 1.4 main prey categories per scat respectively which resulted in diet diversities of 3.9 for jackal and 2.5 for brown hyaena.

    Use of Analgesics in Exotic Felids Formatted: Centered Edward C. Ramsay, DVM Professor, Department of Small Animal Clinical Sciences, University of Tennessee, and Consulting Veterinarian, Knoxville Zoological Gardens, Knoxville, Tennessee. Corresponding address: Ed Ramsay Dept. of Sm Animal Clin Sci C247, Veterinary Teaching Hospital University of Tennessee Knoxville, TN 37996-4544 Phone: 865-755-8219 FAX: 865-974-5554 Email: [email protected] 2 Treatment of pain in domestic and non-domestic cats has been a challenge for the clinician. Many cat species are stoic and show few or very subtle external signs of pain. Additionally, the adverse effects of nonsteroidal antiinflammatory drugs (NSAIDs) in domestic cats are well documented and have discouraged many practitioners from trying novel NSAID’s in exotic felids. As in other animals, each cat’s response to pain and analgesics will vary, necessitating an individualized treatment plan. As a rule, always treat painful felids to effect, and not by rote reliance on published dosages. It is frequently necessary to try different agents and combinations to find which produces the optimal analgesic effect in exotic felids. In order to minimize adverse effects, it is desirable to work toward treatment with the lowest effective dose when treating chronic pain. Non-steroidal Antiinflammatory Drugs NSAIDs are antiinflammatory drugs which act both centrally and peripherally. The primary effects are believed to be caused by their ability to inhibit cyclooxygenase (COX) enzymes in the arachidonic acid metabolism cascade. The COX-1 isoform is regarded as constitutive (continuously expressed) and is responsible for many homeostatic processes, such as maintenance of gastric mucosal integrity, platelet function, and renal autoregulation.

  • The Laughing Hyena by Guy Belleranti
    Name: __________________________________ The Laughing Hyena by Guy Belleranti Have you ever heard an animal laugh? Well, if you haven't, you may want to go to your local zoo and visit the hyena exhibit. These large African mammals are known for their loud, chattering laugh! The laughing hyena is another name for the largest species of hyena, the spotted hyena. While they look kind of like very large dogs they are actually more closely related to cats. However, they aren't exactly cats either. Instead, they're in a family of their own along with their smaller relatives -- the striped and brown hyenas and the insect-eating aardwolfs. Do laughing hyenas really laugh? Their cry does sound a little like laughing, but you wouldn't confuse their voices for human beings. They also make whooping calls, groans, squeals and many other noises to communicate with one another. In fact, spotted hyenas are among Africa's most vocal animals. Spotted hyenas live in groups called clans. Some clans have over 80 members. Each clan marks out a territory and it defends against other clans. Females, who are slightly larger and more aggressive than males, are in charge of the clans. Females are also great moms. They usually give birth to two cubs, and are very protective. They provide milk to their cubs for over a year. Spotted hyenas play an important role as scavengers. They clean up predator's leftovers and even garbage left by humans. With their strong jaws and teeth they can even crush and digest bones. While they are mainly meat eaters, they occasionally eat plants, too.

    MARA PREDATOR CONSERVATION PROGRAMME QUARTERLY REPORT JULY - SEPT 2018 MARA PREDATOR CONSERVATION PROGRAMME Q3 REPORT 2018 1 EXECUTIVE SUMMARY During this quarter we started our second lion & cheetah survey of 2018, making it our 9th consecutive time (2x3 months per year) we conduct such surveys. We have now included Enoonkishu Conservancy to our study area. It is only when repeat surveys are conducted over a longer period of time that we will be able to analyse population trends. The methodology we use to estimate densities, which was originally designed by our scientific associate Dr. Nic Elliot, has been accepted and adopted by the Kenya Wildlife Service and will be used to estimate lion densities at a national level. We have started an African Wild Dog baseline study, which will determine how many active dens we have in the Mara, number of wild dogs using them, their demographics, and hopefully their activity patterns and spatial ecology. A paper detailing the identification of key wildlife areas that fall outside protected areas was recently published.

  • The Wily and Courageous Red Fox: Behavioural Analysis of a Mesopredator at Resource Points Shared by an Apex Predator
    animals Article The Wily and Courageous Red Fox: Behavioural Analysis of a Mesopredator at Resource Points Shared by an Apex Predator Eamonn Wooster *, Arian D. Wallach and Daniel Ramp Centre for Compassionate Conservation, University of Technology Sydney, P.O. Box 123, Ultimo, New South Wales 2007, Australia; [email protected] (A.D.W.); [email protected] (D.R.) * Correspondence: [email protected] Received: 21 September 2019; Accepted: 31 October 2019; Published: 4 November 2019 Simple Summary: The red fox is one of the Earth’s most widespread mammalian predators. Human globalisation has further expanded its range, so that today they are found on most continents. Despite their abundance, knowledge of fox behaviour remains limited. Most studies have observed foxes either in captivity or in their native range where both they and their predators are killed by humans. We conducted a behavioural study on foxes outside of their native range in Australia, at a unique location where all wildlife are protected. We developed an ethogram to explore fox behaviour at resource points shared with a potentially deadly apex predator, the dingo. We were surprised to find that foxes were in a confident state more often than in a cautious state, even leaving territorial markings over those of dingoes. One possible explanation for the confidence of foxes is that the social stability of both foxes and dingoes makes their world more predictable. Abstract: The red fox (Vulpes vulpes) is a widespread and ecologically significant terrestrial mesopredator, that has expanded its range with human globalisation. Despite this, we know relatively little about their behaviour under the wide range of ecological conditions they experience, particularly how they navigate the risk of encounters with apex predators.

  • Character Breakdown BANZAI a Slick Yet Childish Hyena Who Works For
    Character Breakdown BANZAI A slick yet childish hyena who works for Scar. He would be the leader of the group if hyenas weren't so lazy. Look for an outgoing and confident actor who can portray nastiness and gruffness. As Banzai is always featured with Shenzi and Ed, consider auditioning the hyenas in trios. Male or Female, Any Age ED The third member of Scar's trio of lackeys. He has a loud, cackling laugh that is his only form of communication. Ed should be played by an actor who can laugh unabashedly and communicate through physicality and facial expressions rather than words. This role can be played by a boy or girl. Male or Female, Any Age ENSEMBLE The ensemble plays various inhabitants of the Pridelands, such as giraffes, elephants, antelopes, wildebeest, and other creatures you choose to include. This group can have as few or as many performers as your production permits. There are also several moments to showcase individual dancers in "The Lioness Hunt" and "I Just Can't Wait to Be King." HYENAS Scar's army, helping carry out his evil plot to take over the Pridelands. Hyenas are mangy, mindless creatures who sing in "Be Prepared." Male or Female, Any Age LIONESSES The fierce hunters of the Pridelands and featured in "The Lioness Hunt," "The Mourning," and "Shadowland." Female, Any Age MUFASA The strong, honorable, and wise lion who leads the Pridelands. Mufasa should command respect onstage and also show tenderness with his son, Simba. Male, Any Age NALA Grows from a cub to a lioness before she confronts Scar, so cast a more mature actress to play the character beginning in Scene 10, As with older Simba and Young Simba, ensure that this switch in actors performing a single role is clear.

  • GREVY's ZEBRA Equus Grevyi Swahili Name
    Porini Camps Mammal Guide By Rustom Framjee Preface This mammal guide provides some interesting facts about the mammals that are seen by guests staying at Porini Camps. In addition, there are many species of birds and reptiles which are listed separately from this guide. Many visitors are surprised at the wealth of wildlife and how close you can get to the animals without disturbing them. Because the camps operate on a low tourist density basis (one tent per 700 acres) the wildlife is not ‘crowded’ by many vehicles and you can see them in a natural state - hunting, socialising, playing, giving birth and fighting to defend their territories. Some are more difficult to see than others, and some can only be seen when you go on a night drive. All Porini camps are unfenced and located in game rich areas and you will see much wildlife even in and around the camps. The Maasai guides who accompany you on all game drives and walks are very well trained and qualified professional guides. They are passionate and enthusiastic about their land and its wildlife and really want to show you as much as they can. They have a wealth of knowledge and you are encouraged to ask them more about what you see. They know many of the animals individually and can tell you stories about them. If you are particularly interested in something, let them know and they will try to help you see it. While some facts and figures are from some of the references listed, the bulk of information in this guide has come from the knowledge of guides and camp staff.

  • Status of the African Wild Dog in the Bénoué Complex, North Cameroon
    Croes et al. African wild dogs in Cameroon Copyright © 2012 by the IUCN/SSC Canid Specialist Group. ISSN 1478-2677 Distribution Update Status of the African wild dog in the Bénoué Complex, North Cameroon 1* 2,3 1 1 Barbara Croes , Gregory Rasmussen , Ralph Buij and Hans de Iongh 1 Institute of Environmental Sciences (CML), University of Leiden, The Netherlands 2 Painted dog Conservation (PDC), Hwange National Park, Box 72, Dete, Zimbabwe 3 Wildlife Conservation Research Unit, Department of Zoology, University of Oxford South Parks Road, Oxford OX1 3PS, UK * Correspondence author Keywords: Lycaon pictus, North Cameroon, monitoring surveys, hunting concessions Abstract The status of the African wild dog Lycaon pictus in the West and Central African region is largely unknown. The vast areas of unspoiled Sudano-Guinean savanna and woodland habitat in the North Province of Cameroon provide a potential stronghold for this wide-ranging species. Nevertheless, the wild dog is facing numerous threats in this ar- ea, mainly caused by human encroachment and a lack of enforcement of laws and regulations in hunting conces- sions. Three years of surveys covering over 4,000km of spoor transects and more than 1,200 camera trap days, in addition to interviews with local stakeholders revealed that the African wild dog in North Cameroon can be consid- ered functionally extirpated. Presence of most other large carnivores is decreasing towards the edges of protected areas, while presence of leopard and spotted hyaena is negatively associated with the presence of villages. Lion numbers tend to be lower inside hunting concessions as compared to the national parks.
