Movement, Home Range and Habitat Use in Leopard Tortoises (Stigmochelys Pardalis) on Commercial
Movement, home range and habitat use in leopard tortoises (Stigmochelys pardalis) on commercial farmland in the semi-arid Karoo. Martyn Drabik-Hamshare Submitted in fulfilment of the academic requirements for the degree of Master of Science in the Discipline of Ecological Sciences School of Life Sciences College of Agriculture, Engineering and Science University of KwaZulu-Natal Pietermaritzburg Campus 2016 ii ABSTRACT Given the ever-increasing demand for resources due to an increasing human population, vast ranges of natural areas have undergone land use change, either due to urbanisation or production and exploitation of resources. In the semi-arid Karoo of southern Africa, natural lands have been converted to private commercial farmland, reducing habitat available for wildlife. Furthermore, conversion of land to energy production is increasing, with areas affected by the introduction of wind energy, solar energy, or hydraulic fracturing. Such widespread changes affects a wide range of animal and plant communities. Southern Africa hosts the highest diversity of tortoises (Family: Testudinidae), with up to 18 species present in sub-Saharan Africa, and 13 species within the borders of South Africa alone. Diversity culminates in the Karoo, whereby up to five species occur. Tortoises throughout the world are undergoing a crisis, with at least 80 % of the world’s species listed at ‘Vulnerable’ or above. Given the importance of many tortoise species to their environments and ecosystems— tortoises are important seed dispersers, whilst some species produce burrows used by numerous other taxa—comparatively little is known about certain aspects relating to their ecology: for example spatial ecology, habitat use and activity patterns. -

Accepted 11 January 2006 Behavioural frequencies and time budgets for male and female Chersina angulata were recorded in spring, September 2004. The daily activity of the population was 10.51 ± 0.42 h (mean ± CI), but individual males and females were in the open for 2.57 ± 1.12 h and 1.58 ± 1.44 h, respectively. Both sexes spent nearly 3.5 h per day basking with 90% of the basking time in the cover of sparse vegetation. -
The Metabolic Responses of Adult Angulate Tortoises
CIBTech Journal of Zoology ISSN: 2319–3883 (Online) An Open Access, Online International Journal Available at http://www.cibtech.org/cjz.htm 2016 Vol. 5 (2) May-August, pp.61-72/Setlalekgomo and Winter Research Article THE METABOLIC RESPONSES OF ADULT ANGULATE TORTOISE (CHERSINA ANGULATA) TO VARYING AMBIENT TEMPERATURES *Setlalekgomo M.R.1 and P.E.D. Winter2 1Department of Basic Sciences, Botswana University of Agriculture and Natural Resources, Private Bag 0027, Gaborone, Botswana 2Department of Zoology, Nelson Mandela Metropolitan University, Box 77000, Port Elizabeth, 6031, South Africa *Author for Correspondence ABSTRACT Various physiological processes of ectotherms increase with increasing temperature. The effects of varying ambient temperature and gender on the metabolic rate (MR) of adult Chersina angulata were investigated. The tortoises were acclimated to 22 ± 1°C and a 14L:10D photoperiod in an environmentally controlled room prior to MR determination. Oxygen consumption (VO2) rates were determined as index of MR in fasted and resting adult tortoises at eight experimental temperatures (14°C, 18°C, 22°C, 26°C, 30°C, 35°C, 38°C and 40°C). Gender had no significant influence on the MR of C. angulata. MR increased with increasing temperature, but not consistently over the whole range of temperatures tested. MR was strongly temperature dependent, with a Q10 value of 4.13 between 14°C and 26°C. A plateau was detected within a temperature range of 26°C–38°C with a Q10 value of 1.13. The plateau may be a thermal preferendum for C. angulata which may render them advantage to forage at summer temperatures in their natural habitat in the Eastern Cape. -

TSA Magazine 2015
A PUBLICATION OF THE TURTLE SURVIVAL ALLIANCE Turtle Survival 2015 RICK HUDSON FROM THE PRESIDENT’S DESK TSA’s Commitment to Zero Turtle Extinctions more than just a slogan Though an onerous task, this evaluation process is completely necessary if we are to systematically work through the many spe- cies that require conservation actions for their survival. Determining TSA’s role for each species is important for long-term planning and the budgeting process, and to help us identify areas around the globe where we need to develop new field programs. In Asia for example, Indonesia and Vietnam, with nine targeted species each, both emerged as high priority countries where we should be working. Concurrently, the Animal Management plan identified 32 species for man- agement at the Turtle Survival Center, and the associated space requirements imply a signifi- cant investment in new facilities. Both the Field Conservation and Animal Management Plans provide a blueprint for future growth for the TSA, and document our long-term commitment. Failure is not an option for us, and it will require a significant investment in capital and expansion if we are to make good on our mission. As if to test TSA’s resolve to make good on our commitment, on June 17 the turtle conser- vation community awoke to a nightmare when we learned of the confiscation of 3,800 Palawan Forest Turtles in the Philippines. We dropped everything and swung into action and for weeks to come, this crisis and the coordinated response dominated our agenda. In a show of PHOTO CREDIT: KALYAR PLATT strength and unity, turtle conservation groups from around the world responded, deploying Committed to Zero Turtle Extinctions: these species that we know to be under imminent both staff and resources. -
Proposal for Amendment of Appendix I Or II for CITES Cop16

XXX CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA ____________________ Eighteenth meeting of the Conference of the Parties Colombo (Sri Lanka), May 2019 CONSIDERATION OF PROPOSALS FOR AMENDMENT OF APPENDICES I AND II A. Proposal The proponents propose the transfer of Geochelone elegans (Indian Star Tortoise), from CITES Appendix II to Appendix I in accordance with Article II, paragraph 1, of the Convention. Specifically, this species meets the biological criteria found in paragraphs C i) and ii) of Resolution Conf. 9.24 (Rev. CoP16), Annex 1, due to a marked decline in population sizes in the wild observed as ongoing or inferred or projected on the basis of levels or patterns of exploitation, and a high vulnerability to intrinsic (i.e. late maturity, low reproductive output, long generation time and low population recovery potential) and extrinsic (i.e. a decrease in the area and quality of habitat) factors, and a reduction in recruitment due to indiscriminate off take.
