VISUAL RECOGNITION OF THE STATIONARY ENVIRONMENT IN LEOPARD FROGS
Leopard frogs (Rana pipiens) rely on vision to recognize behaviorally meaningful aspects of their environment. The optic tectum has been shown to mediate the frog's ability to recognize and respond to moving prey and looming objects. Nonetheless, atectal frogs are still able to appropriately …

Tails through time: leopard population dynamics in the Little Karoo
… can offer refuge for large carnivores, however leopards (Panthera pardus), can persist outside of these areas and often occupy mixed-use landscapes. Our understanding of how leopards persist over time in mixed-use landscapes is limited, especially in the semi-arid regions of southern Africa. …

A genetic perspective on leopard (Panthera pardus) conservation units across southern Africa
… Africa be considered one conservation unit for leopards (Panthera pardus pardus). This proposal does not take into consideration the likelihood of existing population genetic structure across an increasingly fragmented landscape. Further complicating regional leopard conservation is the …

Leopard population dynamics, trophy hunting and conservation in the Soutpansberg Mountains, South Africa
… interviews in order to investigate leopard population density and dynamics, human-leopard conflict and the potential and effectiveness of trophy hunting as a conservation tool for leopards in the Soutpansberg Mountains, Limpopo Province, South Africa. Results from camera trapping …

The Leopard Men of the Eastern Congo (ca. 1890-1940): history and colonial representation
… research begins with a sculpture representing a “Leopard Man”, threatening to attack a sleeping victim, at the Royal Museum for Central Africa, Belgium. Recently this colonial icon was criticised for presenting a racist image. Leopard men killed on behalf of chiefs in the east of Congo (ca. …

Shark Sim: A Procedural Method of Animating Leopard Sharks Based on Raw Location Data
<p>Fish such as the Leopard Shark (Triakis semifasciata) can be tagged on their fin, released back into the wild, and their location tracked though technologies such as autonomous robots. Timestamped location data about their target is stored. We present a way to procedurally generate an animated …

Estimating leopard density in a coastal protected area of the Western Cape, South Africa
Leopards (Panthera pardus), like many other large carnivores, are facing increasing threats including habitat degradation, illegal hunting, and persecution for perceived or actual livestock depredation. Protected areas remain the cornerstone of conservation efforts throughout the world but they are …

Chemical communication in a declining North American anuran amphibian, the northern leopard frog (lithobates pipiens)
… and functional implications of northern leopard frog (Lithobates pipiens) CRs, identified through collaboration, by conducting a phylogenetic analysis for each CR type identified using a Maximum Likelihood approach (Chapter 1). I incorporated amino acid CR sequences spanning aquatic, …

Scale and impact of the illegal leopard skin trade for traditional use in southern Africa
While leopards (Panthera pardus) currently occupy the most extensive geographic range of all large felids, they are also suffering the highest rate of current range loss amongst large terrestrial carnivores. This is primarily because most leopards still range outside of formally protected areas …

The application of spatial capture-recapture models to investigate leopard ecology and conservation in South Africa
… observe, and hence monitor, in wild populations. Leopards (Panthera pardus) are an iconic and threatened species whose conservation is hampered by a lack of robust population data, in part due to their sparse populations and cryptic nature. I used cameratrap surveys from 27 protected areas in …

The conservation of the snow leopard (panthera uncia) and an action plan for the Indian Himalaya population
The snow leopard (Panthera uncia) inhabits the high-altitude mountains of Central Asia, with 2,710 to 3,386 individuals remaining in the wild. Snow leopards were previously listed as an endangered species on the IUCN Red List, but 2017 saw the species demoted to vulnerable following a reassessment …

Under the skin of a culture: perceptions of fake leopard skin alternatives in the Shembe Baptist Church
Since prehistoric times, big cats such as leopards have had symbolic importance in human culture. They are prized as symbols of power, nobility, ferocity and very often, masculinity. Religious groups have also been known to wear animal skin as part of their ceremonial regalia, typically for …
