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. -

Testudines: Chelidae) of Australia, New Guinea and Indonesia
Zoological Journal of the Linnean Society, 2002, 134, 401–421. With 7 figures Electrophoretic delineation of species boundaries within the genus Chelodina (Testudines: Chelidae) of Australia, New Guinea and Indonesia ARTHUR GEORGES1*, MARK ADAMS2 and WILLIAM McCORD3 1Applied Ecology Research Group, University of Canberra, ACT 2601, Australia 2Evolutionary Biology Unit, South Australian Museum, North Terrace, Adelaide, SA 5001, Australia 3East Fishkill Animal Hospital, 285 Rt 82, Hopewell Junction NY 12533, USA Received February 2001; revised and accepted for publication June 2001 A total of 281 specimens of long-necked chelid turtles (Chelodina) were obtained from drainages of Australia, Papua New Guinea and the island of Roti in Indonesia. Ten diagnosable taxa were identified using allozyme profiles at 45 presumptive loci. Chelodina expansa, C. parkeri, C. rugosa and C. burrungandjii are in a Group A clade, C. longi- collis, C. novaeguineae, C. steindachneri, C. pritchardi and C. mccordi are in a Group B clade, and C. oblonga is in a monotypic Group C clade, with each clade thought to represent a distinct subgenus. Chelodina siebenrocki is syn- onymised with C. rugosa. An eleventh taxon, C. reimanni, could not be distinguished from C. novaeguineae on the basis of allozyme profiles, but it is morphologically distinct. Its status is therefore worthy of further investigation. Three instances of natural hybridization were detected. Chelodina rugosa and C. novaeguineae hybridize in the Gulf country of Queensland, with evidence of backcrossing to C. novaeguineae. Chelodina longicollis and C. novaeguineae hybridize in central coastal Queensland, and C. rugosa and C. burrungandjii hybridize along their zone of contact in the plateau escarpment streams and pools. -

Wells P.O. Box 826, Lismore, New South Wales Australia, 2480 Introduction As a prelude to further work on the Chelidae of Australia, the following considerations relate to the Elseya dentata species complex. See also Wells and Wellington (1984, 1985) and Wells (2002 a, b; 2007 a, b.). Elseya Gray, 1867 1867 Elseya Gray, Ann. Mag. Natur. Hist., (3) 20: 44. – Subsequently designated type species (Lindholm 1929): Elseya dentata (Gray, 1863). Note: The genus Elseya is herein considered to comprise only those species with a very wide mandibular symphysis and a distinct median alveolar ridge on the upper jaw. All members of the latisternum complex lack a distinct median alveolar ridge on the upper jaw and so are removed from the genus Elseya (see Wells, 2007b). This now restricts the genus to the following Australian species: Elseya albagula Thomson, Georges and Limpus, 2006 2006 Elseya albagula Thomson, Georges and Limpus, Chelon. Conserv.

Latitudinal Variation in Egg and Clutch Size in Turtles
Latitudinal variation in egg and clutch size in turtles JOHNB. IVERSON,CHRISTINE P. BALGOOYEN,KATHY K. BYRD,AND KELLYK. LYDDAN Department of Biology, Earlham College, Richmond, IN 473 74, U.S. A.

Zool. 71: 2448-2461. Reproductive and body size data from 169 populations of 146 species (56% of those recognized), 65 genera (75%), and 11 families (92%)of turtles were tabulated to test for latitudinal variation in egg and clutch size. Body-size-adjusted correla- tion analysis of all populations (as well as within most families) revealed (i) a significant negative relationship (r2 = 0.26) between latitude and egg size, (ii) a significant positive relationship (r2 = 0.2 1) between latitude and clutch size, and (iii) no relationship between latitude and clutch mass. Phylogenetic contrast analyses corroborated these patterns. Clutch size was also negatively correlated with egg size across all populations as well as within most families. We evaluate the applicability to turtles of hypotheses postulated to explain such latitudinal patterns for other vertebrate groups. The observed pattern may be the result of latitudinal variation in selection on egg size and (or) clutch size, as well as on the optimal trade-off between these two traits.

HO D GE S 2 1Univeristy of Newcastle, Callaghan, 2300, Australia [[email protected]]; 2Institute of Applied Ecology, University of Canberra, Canberra, ACT 2601, Australia [[email protected]] SU mm ARY . – Australia’s largest snake-necked turtle, Chelodina (Macrochelodina) expansa (Family Chelidae), occurs broadly through the inland rivers and billabongs of eastern and southeastern Australia. The species is cryptic in habit, yet occupies waters heavily exploited and regulated by humans. Traditionally considered a riverine species, recent studies demonstrate that it is more frequently represented in permanent lakes and billabongs connected to main river channels. Typical of many freshwater turtles, C. expansa displays delayed maturity and high adult survivorship. It is carnivorous and feeds primarily on fast-moving prey such as crustaceans and fish, but will also consume carrion. The reproductive biology of C. expansa sets it apart from most other turtles; in response to low temperatures, embryos enter a diapause, which enable them to survive over winter in nests, resulting in a year-long incubation period. -
