Influence of Habitat and Predation on Population Dynamics of the Freshwater Turtle Myuchelys Georgesi
Herpetologica, 69(1), 2013, 46–57 Ó 2013 by The Herpetologists’ League, Inc. INFLUENCE OF HABITAT AND PREDATION ON POPULATION DYNAMICS OF THE FRESHWATER TURTLE MYUCHELYS GEORGESI 1,2,4 1,3 SEAN J. BLAMIRES AND RICKY-JOHN SPENCER 1School of Biological Sciences A08, University of Sydney, NSW 2006, Australia. 2Department of Life Science, Tunghai University, 181 Section 3, Taichung-kan Road, Taichung City, Taiwan 407-04, R.O.C. 3School of Science and Health, Wildlife and Aquatic Ecology Group (Native and Pest Animal Unit), University of Western Sydney, Locked Bag 1797, Penrith NSW 2751, Australia ABSTRACT: Demographic models identify whether animals are vulnerable to local extirpation, but including all ecological parameters across life history stages may be impeded by practical difficulties. When processes acting on certain life stages cannot be measured, extrapolations are often made. A previous study documented that the range of the turtle Myuchelys georgesi is restricted to the Bellinger River, New South Wales, Australia, and its population is stable. We assessed whether M. georgesi selects certain habitats by comparing their distribution among different water holes. We assessed the threat of catfish predation by examining the stomach contents of catfish specimens. We then evaluated whether threats to M. georgesi were likely to have been underestimated by extending our previous demographic model. We did this by revising the previous estimates of adult, juvenile, and hatchling survivorship under hypothetical variations in water hole use and in the presence or absence of catfish predators. We found that M. georgesi preferentially uses moderate to deep water holes. We also found that although catfish 250À400 mm consume hatchling or juvenile turtles, those . -
Photographic Evidence of Nectar-Feeding by the White-Throated Treecreeper Cormobates Leucophaea

Frith Photographic Evidence of Nectar-feeding by the White-throated Treecreeper Cormobates leucophaea CLIFFORD B. FRITH P.O. Box 581, Malanda, Queensland 4885 (Email: [email protected]) Summary. An individual of the north-eastern Australian subspecies of the White-throated Treecreeper Cormobates leucophaea minor was closely observed and photographed while clearly feeding upon nectar from the flowers of an Umbrella Tree Schefflera actinophylla. Although the few other records of nectar-feeding by treecreepers (Family Climacteridae) are reviewed, this note presents the first substantiated evidence of nectar-feeding by Australasian treecreepers. The most recent review of the biology of the Family Climacteridae as a whole described treecreepers as taking nectar from flowers at times (Noske 2007). However, few published records of nectar-feeding by any of the six Australian treecreeper species exist. Of the five species of the genus Climacteris, only one (the Brown Treecreeper C. picumnus) is known to occasionally drink nectar from ironbarks such as Mugga Eucalyptus sideroxylon (V. & E. Doerr, cited in Higgins et al. 2001) and from paperbarks (Orenstein 1977). The Black-tailed Treecreeper C. melanura has been observed feeding on the Banksia-like inflorescences of the FRITH: AUSTRALIAN 104 White-throated Treecreeper Eating Nectar FIELD ORNITHOLOGY Bridal Tree Xanthostemon paradoxus, another myrtaceous species (R. Noske pers. comm.). The White-throated Treecreeper Cormobates leucophaea was recently described as ‘Almost wholly insectivorous, mainly bark-dwelling ants; occasionally take some plant material’ (Higgins et al. -

Preliminary Determination
NSW SCIENTIFIC COMMITTEE Preliminary Determination The Scientific Committee, established by the Threatened Species Conservation Act 1995 (the Act), has made a Preliminary Determination to support a proposal to list the Western Sawshelled Turtle Myuchelys bellii (Gray, 1844) as an ENDANGERED SPECIES in Part 1 of Schedule 1 of the Act, and as a consequence, to omit reference to Bell’s Turtle Myucheles belli (Gray, 1844) from Part 1 of Schedule 2 (Vulnerable species) of the Act. Listing of Endangered species is provided for by Part 2 of the Act. The Scientific Committee has found that: 1. The Western Sawshelled Turtle Myuchelys bellii (Gray, 1844) (family Chelidae) is a medium- sized freshwater chelid turtle, reaching a maximum straight line carapace size of ~230 mm in males and ~300 mm in females (Cogger 2014; Chessman 2015). Cogger (2014) describes this species as “similar in most respect to [the Saw-Shelled Turtle Myuchelys latisternum] Wollumbinia latisternum. Like the latter it is brown above, whitish below, the two colours usually forming a sharply defined line on the side of the face and throat at the level of the angle of the jaws. Usually a distinct yellow stripe from the angle of the jaws, especially in the young. Shell above broadly oval, expanded posteriorly, with a serrated hind edge, except in larger specimens. Plaston moderate, nearly twice as long as broad, the front and rear lobes tapering from the bridge. Intergular shield as wide as or wider than each gular shield. Neck above with conspicuous sharp pointed tubercles. No alveolar ridge on the maxilla. Macrocephaly does not occur. -

Sexual size dimorphism is moderate, with adult males (up to 227 mm carapace length) smaller than females (up to 300 mm). The species occupies streams between 600 and 1100 m elevation that contain permanent pools deeper than about 2 m, frequently with granite boulders and bedrock, and often with underwater caverns formed by boulders, logs, and overhanging banks. In areas of lower water velocity, the typical substratum is coarse granitic sand overlain by fine silt, algal growth, and dense beds of macrophytes. -

A New Species of Bairdemys and the Paleoecology of Stereogenyina
The last marine pelomedusoids (Testudines: Pleurodira): a new species of Bairdemys and the paleoecology of Stereogenyina Gabriel S. Ferreira1, Ascanio D. Rincon´ 2, Andres´ Solorzano´ 2 and Max C. Langer1 1 Laboratorio´ de Paleontologia de Ribeirao˜ Preto, FFCLRP, Universidade de Sao˜ Paulo, Ribeirao˜ Preto, SP, Brazil 2 Laboratorio de Paleontolog´ıa, Centro de Ecolog´ıa, Instituto Venezolano de Investigaciones Cient´ıfcas (IVIC), Caracas, Venezuela ABSTRACT The extinct Stereogenyina turtles form a relatively diverse Podocnemididae lineage, with twelve described and phylogenetically positioned species. They are characterized by a wide geographic and temporal range, from the Eocene of Africa to the Pleistocene of Southeast Asia, and a peculiar palate morphology, with a secondary palate that is unique among side-necked turtles. Here, we describe a new Stereogenyina species, based on an almost complete skull from the middle Miocene Capadare Formation, of Venezuela. A new phylogenetic analysis supports the assignment of the new species to the genus Bairdemys. Based on geometric morphometrics analyses, we related the development of the stereogenyin secondary palate with the acquisition of a durophagous diet. Based on a review of the sedimentary environments where their fossils are found, we also propose that stereogenyins were a marine radiation of podocnemidid turtles, as corroborated by previous studies of fossil eggs and limb morphology. These two inferences allowed us to hypothesize that stereogenyins occupied an ecological niche similar to that of the Submitted 2 April 2015 extant Carettini sea turtles, and that the rise of the latter group may be related to the Accepted 9 June 2015 Stereogenyina diversity fall in the end of the Miocene. -

(Genus Myuchelys), with Special Reference to the Endangered M. Bellii
Vol. 17: 63–71, 2012 ENDANGERED SPECIES RESEARCH Published online April 12 doi: 10.3354/esr00417 Endang Species Res Mitochondrial variation among Australian freshwater turtles (genus Myuchelys), with special reference to the Endangered M. bellii Darren Fielder1,*, Karl Vernes1, Erika Alacs2, Arthur Georges2 1Ecosystem Management, University of New England, Armidale, New South Wales 2351, Australia 2Institute for Applied Ecology, University of Canberra, Australian Capital Territory 2601, Australia ABSTRACT: Identifying species and the relationships among them remains important for assess- ing biodiversity trends and is a critical focus for reversing global biodiversity loss. The saw-shelled turtles of Australia, in the genus Myuchelys, show cryptic diversity and include species that range from Endangered (M. bellii), through those that are locally abundant but extremely limited in dis- tribution (M. georgesi and M. purvisi) to those that are common and widespread (M. latisternum). The Endangered M. bellii is restricted to 3 small isolated populations in the headwaters of the Murray-Darling basin, in the Border, Gwydir and Namoi tributaries. There is no evidence of strong differentiation among these 3 populations based on mitochondrial DNA (mtDNA) diver- gences; rather there is only a shallow genetic structure ranging from 0.1 to 0.3% divergence. The 3 restricted and small populations of the Endangered M. bellii face a number of threatening pro- cesses and require conservation management across state boundaries as a single biological spe- cies. The mtDNA phylogeny supports previous phylogenetic findings of a deep phylogenetic divergence between M. purvisi and M. georgesi (13.5% mtDNA) and the sister taxa relationship of M. latisternum and M.
