    Nile crocodile (Crocodylus niloticus) genetic diversity and population structure, within the lower Kunene and Okavango Rivers of northern Namibia by William F. Versfeld Thesis presented in partial fulfilment of the requirements for the degree of Master of Science in the Faculty of Natural Science at Stellenbosch University Supervisor: Dr Ruhan Slabbert Co-Supervisor: Dr Clint Rhode and Dr Alison Leslie Department of Genetics Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Date: March 2016 Copyright © 2016 Stellenbosch University All rights reserved i Stellenbosch University https://scholar.sun.ac.za Abstract The Nile crocodile has experienced numerous stages of illegal hunting pressures in the mid-20th- century across most of the species’ distribution. The reduced Nile crocodile populations have shown partial recovery and it is currently considered as a “lower risk” / “least concern” species on the Red List of International Union for Conservation of Nature. In Namibia, however, the Nile crocodile is recognised as a protected game species under the Nature Conservation Ordinance No 4 of 1975, allowing trophy hunting of the species only with the issuing of a hunting licence. Census and genetic data of the Nile crocodile is limited or non-existing in Namibia and the country has recently developed a species management plan to conserve the wild populations.

  • Asrsg Action Plan
    IUCN/Species Survival Commission Conservation Communications Fund Contributors In 1992, IUCN’s Species Survival Commission (SSC) established the Conservation Communications Fund to garner support for its expansive Publications Programme which promotes conservation by: (1) providing objective scientific information about biodiversity, habitats, and ecosystems; (2) identifying high priority actions for conservation; and (3) delivering the information and recommendations to natural resource managers, decision-makers, and others whose actions affect the conservation of biodiversity. The SSC’s Action Plans, occasional papers, news magazine Species, Membership Directory, and other publications are supported by a wide variety of generous donors including: The Sultanate of Oman established the Peter Scott IUCN/SSC Action Plan Fund in 1990. The Fund supports Action Plan development and implementation; to date, more than 80 grants have been made from the Fund to Specialist Groups. As a result, the Action Plan Programme has progressed at an accelerated level and the network has grown and matured significantly. The SSC is grateful to the Sultanate of Oman for its confidence in and support for species conservation worldwide. The Chicago Zoological Society (CZS) provides significant in-kind and cash support to the SSC, including grants for special projects, editorial and design services, staff secondments and related support services. The mission of CZS is to help people develop a sustainable and harmonious relationship with nature. The Zoo carries out its mission by informing and inspiring 2,000,000 annual visitors, serving as a refuge for species threatened with extinction, developing scientific approaches to manage species successfully in zoos and the wild, and working with other zoos, agencies, and protected areas around the world to conserve habitats and wildlife.

Principal threats: Habitat destruction Ecology and Natural History Tomistoma (Tomistoma schlegelii) is a freshwater, mound- nesting crocodilian with a distinctively long, narrow snout. It is one of the largest of crocodilians, with males attaining lengths of up to 5 m. The current distribution of Tomistoma extends over lowland regions of eastern Sumatra, Kalimantan and western Java (Indonesia) and Sarawak and Peninsular Malaysia (Malaysia), within 5 degrees north and south of the equator (Stuebing et al. 2006). Tomistoma apparently occurred in southern Thailand historically, but there have been no reports since at least the 1970s and it is probably extirpated there (Ratanakorn et al.

The unit, comprised of members from the Department of Forestry Species Protection and Nature Conservation (BKSDA Lampung), ALAS Indonesia and WATALA (two local groups based in Lampung), Alliance of Indonesian Journalists (AJI Lampung), and the Wildlife Conservation Society (WCS), serves as a field unit to monitor and control wildlife trade, and provides technical assistance in due legal process. In doing so, WCU works closely with law enforcement agencies across Lampung, and with other conservation groups across Sumatra. Government agencies provided important official and logistical support during this first year. WCS’s role has been to train partners, design the monitoring program, providing assistance in gathering evidence and reporting of violations, providing assistance in preparing legal briefs, publicizing the progress of cases, and serving as the coordinator for activities and planning. Local NGOs played have played an important role in obtaining confidential information using their broad network. Equally important, Alliance of Indonesian Journalists (AJI) also played an important role in monitoring the court proceedings and providing intensive media coverage.

Box 4, Mamallapuram, Tamil Nadu 603 104, S.India. *Corresponding author, R. Bonke, E-mail: [email protected] Received: 07. August 2013 / Accepted: 16. October 2014 / Available online: 17. January 2015 / Printed: June 2015 Abstract. We analysed 159 distress calls of five individuals of T. schlegelii for temporal parameters and ob- tained spectral parameters in 137 of these calls. Analyses of G. gangeticus were based on 39 distress calls of three individuals, of which all could be analysed for temporal and spectral parameters. Our results document differences in the call structure of both species. Distress calls of T. schlegelii show numerous harmonics, whereas extensive pulse trains are present in G. gangeticus. In the latter, longer call durations and longer in- tervals between calls resulted in lower call repetition rates. Dominant frequencies of T. schlegelii are higher than in G. gangeticus. T. schlegelii specimens showed a negative correlation of increasing body size with de- creasing dominant frequencies. Distress call durations increased with body size. T. schlegelii distress calls share only minor structural features with distress calls of G. gangeticus. Key words: Tomistoma schlegelii, Gavialis gangeticus, distress calls, temporal parameters, spectral parameters.
