Husbandry Guidelines for (Reptilia:Emydidae) Husbandry Guidelines For Indian Star Tortoise Geochelone elegans (Reptilia:Emydidae) Compiler: Claire Draper Date of Preparation: 30th April 2010 Western Sydney Institute of TAFE, Richmond RUV 30204 Certificate III Captive Animals Lecturer/s: Graeme Phipps, Jacki Salkeld, Brad Walker DISCLAIMER 2 OCCUPATIONAL HEALTH AND SAFETY RISKS One of the biggest OHS risks associated with keeping Indian Star Tortoises in captivity is the possible link between tortoises and the Salmonella Bacteria. Almost all chelonians carry salmonella bacteria within their intestinal tracts, and will usually never suffer any health problems during their life; however Salmonella can be a problem for humans. This is where practicing proper tortoise hygiene and acknowledging common-sense precautions to prevent the spread of Salmonella infection should come into your animal husbandry. What is Salmonella?: Salmonella is a m icroscopic, l iving b acterium, w hich i s m ost c ommonly heard about in unc ooked poultry but i s al so c ommonly f ound in tortoise f aeces and any thing contaminated by your tortoise’s faeces such as the water-dish. Salmonellosis is the infection cause by the salmonella bacteria, which can affect humans, sometimes fatally.111 What are the symptoms of Salmonellosis?: The average person with a healthy immune system may experience fever, diarrhoea, abdominal cramps, headache, chills, and nausea if they have contracted Salmonellosis. These symptoms can appear within 8 to 72 hours after getting infected, and go away after about 4 to 7 days – often with no medical treatment. How does Salmonellosis infection in humans from tortoises occur? Contracting a Salmonellosis infection from a tortoise may occur in three ways: 1. First, the tortoise may roam around in its captive environment, but outside of its enclosure, and leave a trail of salmonella behind. 2. Second, tortoise equipment (terrariums, vivariums, water-dishes, food bowls) might come in contact with human food preparation areas or human eating dishes during cleaning. 3. Third and most common, when you touch a tortoise or some salmonella-contaminated material, i.e. faeces, dirty water-dishes, enclosure substrate, and then transfer the bacteria on your hand to your mouth, eyes, or open wound (scratches, cuts etc.) on your body. What precautions can be taken to prevent Salmonellosis infection? 1. Personal hygiene should be of a high standard at all times. 2. Wear disposable gloves during animal handling or enclosure cleaning, or ensure that all exposed parts of the body are thoroughly washed with an anti-bacterial soap and hot water for at least 20 seconds. 3. Keep all cuts, abrasions, etc. clean and dry and covered by a suitable waterproof dressing. 4. If possible change clothing before and after work and ensure that clothing is thoroughly cleaned after use. 5. Any sick tortoises should be segregated or isolated and treated with caution. 6. Protective clothing should be worn, especially when handling sick or infected animals. Waterproof aprons and boots should be thoroughly washed and disinfected after use. 7. Keep a set of dishes and cleaning materials, such as sponges, that only get used for tortoise use. Never store them with dishes and sponges used for human use. 8. Have a separate area for all tortoise washing tasks, cleaning of dishes, furniture, equipment, tortoise food preparation and human food preparation and cleaning to prevent any cross contamination. • Even though separate areas are used, make sure any sinks, surface that have come in contact with possibly contaminated liquids, substrates or equipment, are 3 sterilised with hot water and a bleach solution or Animal House Veterinary Disinfectant. 9. Ensure arrangements are in place for disposal of any possibly infected materials safely. 10. Never ignore and always suspect any symptoms or lesions such as: - 'Flu-like' (fevers); chills, sweats, fatigue & depressions; unexplained weight losses; gastrointestinal upsets e.g. Diarrhoea, nausea, sickness; muscle aches and stiffness; muscle spasms; hydrophobia; jaundice; conjunctivitis, fits; septic lesions; skin rashes, etc.; and any respiratory problems.16,46,49,58,60 4 TABLE OF CONTENTS 1 INTRODUCTION............................................................................................................................... 8 2 TAXONOMY .................................................................................................................................... 10 2.1 NOMENCLATURE ........................................................................................................................ 10 2.2 SUBSPECIES ................................................................................................................................ 10 2.3 RECENT SYNONYMS ................................................................................................................... 10 2.4 OTHER COMMON NAMES ........................................................................................................... 11 3 NATURAL HISTORY ..................................................................................................................... 11 3.1 MORPHOMETRICS ....................................................................................................................... 12 3.1.1 Mass And Basic Body Measurements ................................................................................... 12 3.1.2 Sexual Dimorphism ............................................................................................................... 13 3.1.3 Distinguishing Features ........................................................................................................ 13 3.2 DISTRIBUTION AND HABITAT ..................................................................................................... 16 3.3 CONSERVATION STATUS ........................................................ERROR!

Snyder Dr. C. Richard Tracy/Dissertation Advisor May 2014 THE GRADUATE SCHOOL We recommend that the dissertation prepared under our supervision by SARAH J. SNYDER Entitled Effects of fire on desert tortoise (Gopherus agassizii) thermal ecology be accepted in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY C. Richard Tracy, Ph.D., Advisor Kenneth Nussear, Ph.D., Committee Member Peter Weisberg, Ph.D., Committee Member Lynn Zimmerman, Ph.D., Committee Member Lesley DeFalco, Ph.D., Graduate School Representative David W. Zeh, Ph. D., Dean, Graduate School May, 2014 i ABSTRACT Among the many threats facing the desert tortoise (Gopherus agassizii) is the destruction and alteration of habitat. In recent years, wildfires have burned extensive portions of tortoise habitat in the Mojave Desert, leaving burned landscapes that are virtually devoid of living vegetation. Here, we investigated the effects of fire on the thermal ecology of the desert tortoise by quantifying the thermal quality of above- and below-ground habitat, determining which shrub species are most thermally valuable for tortoises including which shrub species are used by tortoises most frequently, and comparing the body temperature of tortoises in burned and unburned habitat. To address these questions we placed operative temperature models in microhabitats that received filtered radiation to test the validity of assuming that the interaction between radiation and radiation-absorbing properties of the model can result in a single, mean radiant absorptance regardless of whether the incident solar radiation is direct unfiltered or filtered by plant canopies, using the desert tortoise as a case study.

  • Indian Star Tortoise Care
    RVC Exotics Service Royal Veterinary College Royal College Street London NW1 0TU T: 0207 554 3528 F: 0207 388 8124 www.rvc.ac.uk/BSAH INDIAN STAR TORTOISE CARE Indian star tortoises originate from the semi-arid dry grasslands of Indian subcontinent. They can be easily recognised by the distinctive star pattern on their bumpy carapace. Star tortoises are very sensitive to their environmental conditions and so not recommended for novice tortoise owners. It is important to note that these tortoises do not hibernate. HOUSING • Tortoises make poor vivarium subjects. Ideally a floor pen or tortoise table should be created. This needs to have solid sides (1 foot high) for most tortoises. Many are made out of wood or plastic. A large an area as possible should be provided, but as the size increases extra basking sites will need to be provided. For a small juvenile at least 90 cm (3 feet) long x 30 cm (1 foot) wide is recommended. This is required to enable a thermal gradient to be created along the length of the tank (hot to cold). • Hides are required to provide some security. Artificial plants, cardboard boxes, plant pots, logs or commercially available hides can be used. They should be placed both at the warm and cooler ends of the tank. • Substrates suitable for housing tortoises include newspaper, Astroturf, and some of the commercially available substrates. Natural substrate such as soil may also be used to allow for digging. It is important that the substrates either cannot be eaten, or if they are, do not cause blockages as this can prove fatal.

Palo Verde St., Phone: (480) 706-8478 Suite #1 Fax: (480) 393-3915 Gilbert, AZ 85296 Emergencies: Page (602) 351-1850 Russian Tortoise Care Scientific Taxonomy/name: Testudo horsfieldi Avg. carapace length: Males average around 5.5 inches and 1.3 pounds. Females average around 7.5 inches and 3 pounds. Natural location: Dry/arid, hot areas around the Mediterranean Sea (i.e. parts of Turkey, Afghanistan, Russia, Iran, China, and Pakistan). Russian tortoises live in burrows for nine months of the year. They are the only land tortoise (Testudo spp.) without a hinge on their plastron near the rear legs, and the only land tortoise with only four claws/toes on each foot. Temperature: 70-80 degrees Fahrenheit with basking area of 90 degrees. For tortoises kept inside, keep thermometers at various locations in the enclosure in order to check the temperature in their environment. Humidity: 30-50% (dry environment). Use a hydrometer to check humidity levels in the enclosure. Lighting: Natural sunlight (not blocked by windows) is the best source of light for tortoises (and other reptiles)! If being kept indoors during the winter or due to an illness, use a broad- spectrum heat bulb. The most efficient light source is the Exo Terra Solar Glo. It is a mercury vapor bulb that emits heat, UVB, and UVA. UV light has multiple benefits, including calcium metabolism and improved appetite and activity. Proper calcium metabolism helps protect against metabolic bone disease. Follow manufacture directions on proper installation and use a clamp lamp with a ceramic fixture to prevent melting.

  • 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.
