Abstract:

As ecosystems become increasingly fragmented, there has been a proliferation of research into fields such as resource use, movement ecology and habitat connectivity. To understand how species may adapt to threats associated with habitat fragmentation it is necessary to study these processes in dispersing individuals. However, this is seldom done. Dispersal is one of the most important life-history traits involved in species persistence and evolution, but the consequences of dispersal are determined primarily by those that survive to reproduce. Although dispersal is most effectively studied as

Abstract:

Single-species research dominates the field of ecology; however there is a growing appreciation of the importance of a multi-species approach to holistic conservation. Carnivores exert a top-down control on other species, and are vital components of stable ecosystem functioning. Physiologically adapted for predation upon other animals, competition between carnivores can be particularly aggressive; frequently resulting in mortality, and even population suppression. Big cat research has historically focused on those species that are most easily observable; in particular the lion Panthera leo. Th

Providing captive animals with optimal welfare is a key aim of zoos and aquariums and has traditionally been evaluated through “input measures”. These measures are important but fail to capture the experience of the animal, a critical component of welfare. This project is a first step towards developing “output measures” - positive animal-based metrics – to be used as a benchmark to assess the welfare. This study provided a thorough account of captive lion behaviour in modern facilities and compared this behaviour to that of wild conspecifics. Nine adult African lions from three facilities wer

Abstract Lion populations in West and Central Africa are small and fragmented. In areas where park management is weak, threats will likely facilitate the extinction of the lion. Wildlife management requires knowledge of the population estimate. The population of lions in Waza National Park (Waza NP) was assessed by individual identification of members in the population. The population was assessed to comprise of 14–21 adult individual lions. The age structure was skewed towards adults; cubs comprised 22% of all lions identified while the sex ratio was 1 : 3.

Abstract:

This thesis combines behavioral observations of African lions (Panthera leo) with genetic analyses, in an attempt to clarify causes and consequences of lion group living. The numerous complex cooperative behaviors of lions present an excellent opportunity to investigate the evolution and maintenance of group living. This thesis focuses on female group living and male dispersal patterns. Lion sociality is found to be more complex than previously thought. Short dispersal distances result in strong kinship ties among prides, creating the potential for kin selection to operate among prides. Simult

Fear of predation can have a major impact on the behaviour of prey species. Despite recent codifying of the concept of the ecology of fear, there has been relatively little focus on how these ideas apply to large carnivore species which, although not prey sensu stricto, may experience fear as a result of threats from humans. This thesis argues that large mammalian carnivores are subject to a Landscape of Fear similar to that described for prey species, and will respond behaviourally to fear of human-caused mortality. The idea of a "Landscape of Coexistence" is introduced to denote the perceive

Intraguild competition and predation have been recognised as important ecological factors influencing the population dynamics of carnivores. The effects of these interactions are often asymmetrical due to a size-related dominancy hierarchy.

Here I investigate the ecological and behavioural mechanisms by which cheetahs (Acinonyx jubatus) coexist with competitively stronger lions (Panthera leo) and spotted hyaenas (Crocuta crocuta).

The aim of this thesis was to process the data and information with predictive capabilities of breeding lion (Panthera leo) and tiger (Panthera tigris) in the Czech zoos including their subspecies. The results was based on the yearbooks of the Union of Czech and Slovak Zoos (UCSZOO), and I try complemented it with adequate information from bulletins of an expert commission UCSZOO for subfamilies Pantherinae and Acinonynchinae: Baghira 1/2004 - 11/2014. I assessed the development of the last 24 years (1990 - 2014). If possible I complete it with a brief summary of the relevant facts from the hi

Thesis (MTech. degree in Game Range Management.)--Tshwane University of Technology, 2010.<br>Lion (Panthera leo) social organisation in the Northern Tuli Game Reserve, Botswana, and the Venetia Limpopo Nature Reserve, South Africa, was investigated. Situated 20 km apart, the Northern Tuli Game Reserve is predominantly unfenced with unrestricted animal movements, as opposed to the Venetia Limpopo Nature Reserve which is completely fenced. Historically both lion populations have faced various but similar pressures such as safari hunting, snaring, poisoning and killing due to perceived conflict w

Abstract:

Nos últimos anos a estrutura e o funcionamento dos ecossistemas têm-se alterado a uma velocidade alarmante, em grande parte devido à extinção de inúmeras espécies. Portanto, cabe-nos a todos, enquanto sociedade, tomar medidas que visem o controlo desta situação, uma vez que é o Homem o maior responsável por esta crise. No que respeita à conservação de espécies animais, os zoos e os médicos veterinários são hoje ferramentas indispensáveis e têm vindo a adotar novas funções no seguimento da problemática da extinção. A conservação é um tema complexo e extenso e como tal, seria extremamente dífi

While many studies have been done on Lions, relatively little work has been conducted on how they interact with local habitats and the factors of importance in determining home ranges and territories. The interactions between predators and patchily distributed resources and the basic tenets of Ideal Free Distribution theory have been used in this study as the basis in explaining how lions distribute themselves in space and why they choose particular areas above others in regards territory location. The study was conducted in the Hluhluwe-Umfolozi Park, South Africa and involved the use of hist

While a decrease of wild felid population has led to disruption of conservation programme, recent studies have shown the importance of immune regulation for determining health outcomes and co-infection. Immunoglobulin G is important for detecting and evaluating responses to infectious diseases and vaccination. But, there is limited information on felid immunoglobulins and their role for functional immunity. This study aimed at isolating and characterizing lion’s immunoglobulin G. Lions’ sera (n = 68) were processed using the MagReSyn® magnetic beads and the final protein concentra

Abstract:

African Lions (Panthera leo) are an keys species in many natural ecosystems in Africa and provide income and ecosystem services to many human communities. They directly limit herbivore populations, which in turn maintain grasslands and associated systems. Those ecosystems have degraded in recent decades and the concurrent decline in lion population is believed to play a role. I investigated factors affecting lion behaviour and ecology including the effect of seasonal variation in wild prey herd size. Current levels of herbivore prey are significantly low

Abstract:

This thesis addresses the question of whether Serengeti lions choose foraging sites that facilitate the capture of prey, or whether they choose foraging sites where prey are most abundant. The alternate choices between good habitats and high prey densities have rarely been addressed in resource selection studies of predators. The observed distributions of kills and scavenges by lions were compared to the predictions of two alternate hypotheses; (a) if lions forage in areas that facilitate the capture of prey, such as areas with cover, then more kills and scavenges should occur in these areas t

Abstract:

Mycobacterium bovis is the causative agent of bovine tuberculosis (BTB) which has a diverse host range. The maintenance host of BTB in South Africa is the African buffalo (Syncerus caffer). It is believed that lions get infected by feeding on infected buffalo or through wounds. The spread of the disease amongst lions has raised concern regarding the future of the animals and the impact on tourism in the country. Diagnoses of tuberculosis in free ranging wildlife is often dependent on post-mortem samples due to logistical challenges, the use of the lion specific interferon gamma release

Abstract:

The ecological role of apex predators in ecosystems is increasingly recognized not only as a result of their affects on prey species, but also on the numbers and behaviour of other predator species within their guilds. In an African context, dominant apex predators such as lions (Panthera leo) and spotted hyaenas (Crocuta crocuta) have been implicated in limiting endangered intraguild species such as wild dogs (Lycaon pictus) via direct intraguild interactions, such as interference and predation. As a result of this it has been predicted that spatial and temporal refugia are critical for wild
