Suggested Guidelines for Reptiles and Amphibians Used in Outreach
RECOMMENDATIONS FOR REPTILES AND AMPHIBIANS USED IN OUTREACH PROGRAMS Compiled by Diane Barber, Fort Worth Zoo Originally posted September 2003; updated February 2008 INTRODUCTION This document has been created by the AZA Reptile and Amphibian Taxon Advisory Groups to be used as a resource to aid in the development of institutional outreach programs. Within this document are lists of species that are commonly used in reptile and amphibian outreach programs. With over 12,700 species of reptiles and amphibians in existence today, it is obvious that there are numerous combinations of species that could be safely used in outreach programs. It is not the intent of these Taxon Advisory Groups to produce an all-inclusive or restrictive list of species to be used in outreach. Rather, these lists are intended for use as a resource and are some of the more common species that have been safely used in outreach programs. A few species listed as potential outreach animals have been earmarked as controversial by TAG members for various reasons. In each case, we have made an effort to explain debatable issues, enabling staff members to make informed decisions as to whether or not each animal is appropriate for their situation and the messages they wish to convey. It is hoped that during the species selection process for outreach programs, educators, collection managers, and other zoo staff work together, using TAG Outreach Guidelines, TAG Regional Collection Plans, and Institutional Collection Plans as tools. It is well understood that space in zoos is limited and it is important that outreach animals are included in institutional collection plans and incorporated into conservation programs when feasible. -
ECUADOR – Galapagos Giant Tortoises Stolen From
CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA NOTIFICATION TO THE PARTIES No. 2018/076 Geneva, 30 October 2018 CONCERNING: ECUADOR Galapagos giant tortoises stolen from breeding center 1. This Notification is being published at the request of Ecuador. 2. The CITES Management Authority of Ecuador informed the Secretariat that on 27 September 2018, the Galapagos National Park Directorate filed a criminal complaint in Ecuador following the theft of 123 live Galapagos giant tortoises (Chelonoidis niger) from the Galapagos National Park breeding center on Isabela Island. 3. The Galapagos giant tortoise (Chelonoidis niger1) is included in CITES Appendix I. 4. The stolen tortoises range from one to six years in age. One-year-old Galapagos giant tortoises may be around six centimetres in carapace length and weigh an estimated 200 grams. A six-year-old Galapagos giant tortoise could range from 12 to 30 centimetres in carapace length, and weigh around two kilograms. 5. The likely market for the stolen specimens is outside of Ecuador, and the CITES Management Authority of Ecuador therefore requests that the present Notification be distributed as widely as possible among police, customs and wildlife enforcement authorities. 6. Parties are requested to inform the CITES Management Authority of Ecuador should any permits or certificates regarding trade in these specimens be received. The Management Authority of Ecuador also requests that CITES Management Authorities do not approve any export, import or re-export permit applications related to this species before consulting with the CITES Management Authority of Ecuador. 7. Parties that seize illegally traded specimens of Chelonoidis niger are also requested to communicate information about these seizures to the Management Authority of Ecuador. -
Indian Freshwater Turtles, Which Are Usually Bigger
Fantastic Facts Indian Part 3 Freshwater Turtles Conservation / Threat Status of Turtles Many turtles, terrapins and tortoises are threatened with extinction, that is, dying out completely. Listed below are the turtles discussed in this article (from Part 1 to 3), with their status, or prospects of survival. Name Status (Global) Assam Roofed Turtle Endangered Cochin Forest Cane Turtle Endangered Crowned River Turtle Vulnerable Rock Terrapin Near Threatened Indian Flapshell Turtle Least Concern Indian Softshell Turtle Vulnerable Indian Narrow-headed Softshell Turtle Endangered Red-crowned Roofed Turtle Critically Endangered Northern River Terrapin Critically Endangered THE CATEGORIES Critically Endangered -- This is the highest category that a species can be assigned before “extinction”. It represents a “last ditch” effort to provide a warning to wildlife agencies and governments to activate management measures to protect the species before it disappears from the face of the earth. When a species is Critically Endangered, usually its chances of living for the next 100 years are very low. Often, its chances of surviving even for 10 years are not good at all ! Endangered -- This is the second highest threat category that a species can be assigned before it becomes further threatened e.g. Critically Endangered or Extinct. When a species is Endangered, its chances of survival as a species for the next 100 years are low. Vulnerable -- The IUCN Red List defines Vulnerable as when a species is not Critically Endangered or Endangered, but is still facing a high risk of extinction in the wild. This is the first threat category for ranking a species when it has some serious problems from human-related threats. -

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. -

Species Description Taxonomy Distribution
Gopher Tortoise Species Description Tortoises can be observed on all major landmasses in the world except for Australia and Antarctica. The Gopher Tortoise (Gopherus polyphemus) is one of four species that lives only in North America. It has a large dark-brown to grayish shell, elephantine limbs and a large grayish-black rounded head. Its shovel-like forefeet are used to excavate burrows that provide shelter (Ernst et al., 1994). The Gopher Tortoise can reach lengths of more than 35 centimeters and weigh over 10 kilograms, Photo: Pete Oxford and there are physical differences between males and females. Female tortoises have a flattened bottom shell, or plastron, and a small tail whereas males exhibit a highly concave plastron and large tail. Male Gopher Tortoises also have two visible scent glands beneath the chin (Ernst et al., 1994). Taxonomy The generic name of the Gopher Tortoise, Gopherus, is derived from the word gopher that was used to describe the burrowing habits of this species. The species name polyphemus refers to a cave-dwelling mythical creature (Ashton and Ashton, 2008). Daudin was the first to describe the Gopher Tortoise as polyphemus in 1802. Rafinesque used this species as the type or standard to define the features of Gopherus and assign this generic name to the North American tortoises (Schmidt, 1953). All four species in this genus exhibit adaptations for burrowing such as claws and flattened forelimbs. However, they can be distinguished based on anatomical features including limb-bone and skull structure (Ernst et al., 1994). The Gopher Tortoise is most closely related to the larger Mexican or Bolson Tortoise (G.
