The Ecology of Large-Spotted Genets Within an Urban Landscape and to Determine What Factors Facilitate Their Ability to Persist in an Urban Environment
i The ecology of large-spotted genets within an urban landscape Craig D. Widdows Submitted in fulfilment of the academic requirements for the degree of Doctor of Philosophy In the Discipline of Ecological Sciences School of Life Sciences College of Agriculture, Science and Engineering University of KwaZulu-Natal Pietermaritzburg Campus 2015 i ABSTRACT Urbanization is one of the most damaging and rapidly expanding forms of anthropogenic landscape modification and is having profound consequences on biodiversity worldwide. The global increase in urbanization has resulted in exclusion of many carnivore species from human- altered landscapes due to a variety of anthropogenic impacts. However, despite the negative impacts of urbanization on carnivores, certain species such as large-spotted genets (Genetta tigrina) exhibit an ability to persist within urban areas. Despite their extensive distribution range, large-spotted genets are poorly studied in comparison to other African carnivores, with a handful of studies conducted on genetics, activity patterns and diet. Furthermore, no studies have focused on their ecology in an urban environment. There have been increasing reports of large-spotted genets within urban areas throughout KwaZulu-Natal, South Africa. The mosaic of patches of native vegetation within this urban landscape provides habitats for a variety of wildlife species. The main aim of the study was to investigate the ecology of large-spotted genets within an urban landscape and to determine what factors facilitate their ability to persist in an urban environment. Residential interviews were conducted to ascertain information pertaining to behavioural observations, land use as well as wildlife conflict and public perceptions of genets. Chi-square (2) goodness-of-fit tests were used to determine significant differences in the frequency of responses. -

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.

Educator Packet
Educator Packet Animal Survival Strategies Grade Level: 4th Grade (can be adapted to 2nd and 3rd grade) Overview: Students will observe pieces of art from the Art and Animal exhibit and learn about various Ohio wildlife species and the ways they adapt to survive extremes in weather and environments. Materials: Wildlife board game and handout on animal traits. Content Standards: Science: Changes in an organism’s environment are sometimes beneficial to its survival and sometimes harmful. Plants and animals have life cycles that are part of their adaptations for survival in their natural environments. Organisms that survive pass on their traits to future generations Social Studies: Places and Regions: The regions of the United States known as the North, South and West developed in the early 1800s largely based on their physical environments and economies. Human Systems: People have modified the environment since prehistoric times. There are both positive and negative consequences for modifying the environment in Ohio and the United States. Background/Key Ideas: Students will play a game that includes reproductions of several pieces of art from the exhibit Art and the Animal. All pieces are images of animals that can be found in Ohio. Students will use previous knowledge and deductive reasoning to match the correct facts (classifications, and characteristics) to each animal. After completion of the game, facts about adaptation will be further addressed with a silly exercise where the classroom teacher is outfitted with various props which represent each of the animals from the game. Procedures: Introduction: “Hello and welcome to another round of Adapt to Survive; the game where you compete to match Ohio’s wildlife to the correct category. -

Aspects of the Ecology of Spotted Hyena (Crocuta Crocuta) in Relation to Prey Availability, Land Use Changes and Conflict with Humans in Western Zimbabwe
Aspects of the ecology of spotted hyena (Crocuta crocuta) in relation to prey availability, land use changes and conflict with humans in western Zimbabwe Mlamuleli Mhlanga Submitted in fulfilment of the academic requirements for the degree of DOCTOR OF PHILOSOPHY In the Discipline of Ecological Sciences In the School of Life Sciences College of Agriculture, Engineering and Science University of KwaZulu-Natal Pietermaritzburg Campus 2018 ii ABSTRACT Patch selection by carnivores is affected by various factors including availability of prey and denning areas, extent of vegetation cover, competition from sympatric large carnivores and anthropogenic habitat change among other variables. Understanding the influence of such factors is fundamental in the management of the carnivores. The study investigated spotted (i) hyena occupancy and (ii) co-occurrence with mesocarnivores in Zambezi National Park, Matetsi Safari (hunting) Area and Dimbangombe Ranch (mixed livestock and wildlife) in western Zimbabwe during the dry and wet seasons of 2014 and 2015 using camera traps. First, habitat characteristics, potential major prey and possible disturbance factors were modelled using the occupancy modelling approach to quantify habitat occupancy of the spotted hyena. It was found that the spotted hyena mean site occupancy was high (ψ = 0.617, SE = 0.147 and ψ = 0.502, SE = 0.107 for wet and dry seasons respectively). Furthermore, spotted hyena habitat occupancy increased in clayey soil and grasslands in the national park and hunting area, a behaviour attributed to denning preferences and possibly prey movement. Management priorities should focus on improving habitats for wild prey outside protected areas while preserving clayey areas for enhanced productivity of the spotted hyena inside protected areas. -

Web Ecology 7: 53–62. Trophic niche partitioning between two native and two exotic carnivores in SW Portugal Maria João Santos, Bruno Miguel Pinto and Margarida Santos-Reis Santos, M. J., Pinto, B. M. and Santos-Reis, M. Trophic niche partitioning between two native and two exotic carnivores in SW Portugal. – Web Ecol. 7: 53–62. The introduction of exotic species is one of the most pervasive consequences of the increased human mobility. The most known negative effects are the decrease or extinc- tion of natives. The common-genet, Genetta genetta, and the Egyptian mongoose, Her- pestes ichneumon, were introduced in the Iberian Peninsula in the 15th and 19th centu- ries, respectively. The competitive exclusion principle defines that two ecologically simi- lar species cannot coexist. Thus, some degree of partitioning has to occur in species realized niche, which can occur at the trophic level. To test this hypothesis of partitio- ning we compared the diet of these two exotic species with that of two native species (stone marten, Martes foina, and red fox, Vulpes vulpes). The results show a high degree of overlap (>45%) between the diets of species similar in their feeding strategies (arbore- al and ground feeding). Nonetheless, at the finer scale of prey consumed at the species level some differences are found between the native and exotic species. These results suggest that if coexistence is due to trophic niche partitioning it only occurs at the level of the consumed species. However, coexistence may also be due to a combination of different strategies (home-range size, time and space use) that structured the different realized niches of each species. -

M. PADIAL,E.AÂVILA,andJ.M.GIL-SAÂNCHEZ Group for the study and conservation of nature Signatus and Department of Animal Biology, University of Granada, Spain. Receipt of Ms. 31. 01. 2001 Acceptance of Ms. 30. 07. 2001 Abstract The feeding habits of two carnivorous opportunists, red fox 3Vulpes vulpes) and stonemarten 3Martes foina), have been compared in two Mediterranean mountain habitats 3mesic and xeric), lo- cated in the Sierra Nevada National Park 3SE Spain), between April 1997 and March 1998. The ana- lysis of scats revealed a very important interspecific trophic niche overlap in the mesic habitat. In the xeric habitat the differences were significant and the overlap moderate. Seasonal variations ex- isted in the degree of overlap, which reached its highest level in winter in the mesic habitat and in spring in the xeric habitat. The results indicated that the availability of food in each habitat was important in determining the divergence of the diets. Thus, in the mesic habitat, competition could be possible, although it was not important enough to cause a habitat segregation. Martens seemed to be more adaptive than foxes, probably due to their smaller size and arboreal life, allowing them to exploit fruit which is not as profitable for the fox. Foxes based their diet on small mammals, car- rion and cultivated fruit in both habitats.
