A high degree of variation was found in the plastral formula and in the shape and size of the intergular scute. This study suggests that the Amazon population of matamatas is different from the Orinoco population in the following characters: shape ofthe carapace, plastral pigmentation, and coloration on the underside of the neck. Additionatly, a preliminary analysis indicates that the two populations could be separated on the basis of the allometric growth of the carapace in relation to the plastron.

Demographic Consequences of Superabundance in Krefft's River
i The comparative ecology of Krefft’s River Turtle Emydura krefftii in Tropical North Queensland. By Dane F. Trembath B.Sc. (Zoology) Applied Ecology Research Group University of Canberra ACT, 2601 Australia A thesis submitted in fulfilment of the requirements of the degree of Masters of Applied Science (Resource Management). August 2005. ii Abstract An ecological study was undertaken on four populations of Krefft’s River Turtle Emydura krefftii inhabiting the Townsville Area of Tropical North Queensland. Two sites were located in the Ross River, which runs through the urban areas of Townsville, and two sites were in rural areas at Alligator Creek and Stuart Creek (known as the Townsville Creeks). Earlier studies of the populations in Ross River had determined that the turtles existed at an exceptionally high density, that is, they were superabundant, and so the Townsville Creek sites were chosen as low abundance sites for comparison. The first aim of this study was to determine if there had been any demographic consequences caused by the abundance of turtle populations of the Ross River. Secondly, the project aimed to determine if the impoundments in the Ross River had affected the freshwater turtle fauna. Specifically this study aimed to determine if there were any difference between the growth, size at maturity, sexual dimorphism, size distribution, and diet of Emydura krefftii inhabiting two very different populations. A mark-recapture program estimated the turtle population sizes at between 490 and 5350 turtles per hectare. Most populations exhibited a predominant female sex-bias over the sampling period. Growth rates were rapid in juveniles but slowed once sexual maturity was attained; in males, growth basically stopped at maturity, but in females, growth continued post-maturity, although at a slower rate. -
Can Unwanted Suburban Tortoises Rescue Native Hawaiian Plants?
CAN UNWANTED SUBURBAN TORTOISES RESCUE NATIVE HAWAIIAN PLANTS? by David A. Burney, James O. Juvik, Lida Pigott Burney, and Tomas Diagne 104 THE TORTOISE ・ 2012 hrough a series of coincidences, surplus pet tortoises in Hawaii may end up offering a partial solution to the seemingly insurmountable challenge posed by invasive plants in the Makauwahi Cave Reserve Ton Kaua`i. This has come about through a serendipitous intersection of events in Africa, the Mascarene Islands, North America, and Hawaii. The remote Hawaiian Islands were beyond the reach of naturally dispersing island tortoises, but the niches were apparently still there. Giant flightless ducks and geese evolved on these islands with tortoise-like beaks and other adaptations as terrestrial “meso-herbivores.” Dating of these remarkable fossil remains shows that they went extinct soon after the arrival of Polynesians at the beginning of the last millennium leaving the niches for large native herbivores entirely empty. Other native birds, including important plant pollinators, and some plant species have also suffered extinction in recent centuries. This trend accelerated after European settlement ecosystem services and a complex mix of often with the introduction of many invasive alien plants conflicting stakeholder interests clearly requires and the establishment of feral ungulate populations new paradigms and new tools. such as sheep, goats, cattle, and European swine, as Lacking any native mammalian herbivores, the well as other insidious invasives such as deer, rats, majority of the over 1,000 native Hawaiian plant mongoose, feral house cats, and even mosquitoes, species on the islands have been widely regarded which transmit avian malaria to a poorly resistant in the literature as singularly lacking in defensive native avifauna. -

Origins of Endemic Island Tortoises in the Western Indian Ocean: a Critique of the Human-Translocation Hypothesis
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2017 Origins of endemic island tortoises in the western Indian Ocean: a critique of the human-translocation hypothesis Hansen, Dennis M ; Austin, Jeremy J ; Baxter, Rich H ; de Boer, Erik J ; Falcón, Wilfredo ; Norder, Sietze J ; Rijsdijk, Kenneth F ; Thébaud, Christophe ; Bunbury, Nancy J ; Warren, Ben H Abstract: How do organisms arrive on isolated islands, and how do insular evolutionary radiations arise? In a recent paper, Wilmé et al. (2016a) argue that early Austronesians that colonized Madagascar from Southeast Asia translocated giant tortoises to islands in the western Indian Ocean. In the Mascarene Islands, moreover, the human-translocated tortoises then evolved and radiated in an endemic genus (Cylindraspis). Their proposal ignores the broad, established understanding of the processes leading to the formation of native island biotas, including endemic radiations. We find Wilmé et al.’s suggestion poorly conceived, using a flawed methodology and missing two critical pieces of information: the timing and the specifics of proposed translocations. In response, we here summarize the arguments thatcould be used to defend the natural origin not only of Indian Ocean giant tortoises but also of scores of insular endemic radiations world-wide. Reinforcing a generalist’s objection, the phylogenetic and ecological data on giant tortoises, and current knowledge of environmental and palaeogeographical history of the Indian Ocean, make Wilmé et al.’s argument even more unlikely.

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. -

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.
