FRESHWATER CRAYFISH (FAMILY PARASTACIDAE) OF QUEENSLAND WITH AN ApPENDIX DESORIBING OTHlm AV5'lHALIAN SPEClEf'. By E. F. HIEK. (;ommonwealth Scientific and Industrial l~csearch Organization - Divhdon of Entomology, Canberra, A.C.T. (Figures 1-13.) Freshwater crayfish occur in almost every body of fresh water from artificial damfl and natural billabongs (I>tanding water) to headwater creeks and large rivers (flowing water). Generally the species are of considerable size and therefore easily collected, but even so many of the larger forms are unknown scientifically. This paper deals with all the species that have been collected from Queensland. It also includes a few species from New South Wales and other States. No doubt additional species will be found and some of the mOre variable series, at present included under the one specific namc, will be further subdivided. From Queensland nine species are described as new, making a total of seventeen species (of three genera) recorded from that State. The type localities of all but two of these species are in Queensland but some are not restricted to the State. Clark's 1936 and subsequent papers have been used as the basis for further taxonomic studies of the Australian freshwater crayfish.

  • Geographical Distribution Patterns of South American Side-Necked Turtles (Chelidae), with Emphasis on Brazilian Species

    Geographical Distribution Patterns of South American Side-Necked Turtles (Chelidae), with Emphasis on Brazilian Species

    Rev. Esp. Herp. (2005) 19:33-46 Geographical distribution patterns of South American side-necked turtles (Chelidae), with emphasis on Brazilian species FRANCO LEANDRO SOUZA Universidade Federal de Mato Grosso do Sul, Centro de Ciências Biológicas e da Saúde, Departamento de Biologia, 79070-900 Campo Grande, MS, Brazil (e-mail: [email protected]) Abstract: The Chelidae (side-necked turtles) are the richest and most widespread turtle family in South America with endemic patterns at the species level related to water basins. Based on available literature records, the geographic distribution of the 22 recognized chelid species from South America was examined in relation to water basins and for the 19 Brazilian species also in light of climate and habitat characteristics. Species-distribution maps were used to identify species richness in a given area. Parsimony analysis of endemicity (PAE) was employed to verify the species-areas similarities and relationships among the species. For Brazilian species, annual rainfall in each water basin explained 81% of variation in turtle distribution and at a regional scale (country-wide) temperature also influenced their distribution. While rainfall had a significant positive relationship with species number in a given area, a negative but non-significant relationship was identified for temperature. Excepting an unresolved clade formed by some northern water basins, well-defined northern-northeastern and central-south groups (as identified for water basins) as well as biome differentiation give support to a hypothesis of a freshwater turtle fauna regionalization. Also, a more general biogeographical pattern is evidenced by those Brazilian species living in open or closed formations.

The aim of this study was to analyze the precision of the portable refractometer in determining the concentration of total serum proteins in Podocnemis expansa and Phrynops geoffroanus. A total of 26 animals were used. The blood samples were collected from the supraoccipital sinus and stored in tubes without anticoagulant. Total serum protein was determined using both the biuret reaction and refractometry. The total serum protein mean concentration (g dL-1) with biuret method and refractometry for P. expansa were 3.16 and 3.2; and for P. geoffroanus were 3.56 and 2.72, respectively. These results indicate that total serum protein values can be determined with precision in P. expansa and P. geoffroanus using a portable refractometer.

Abstract. A recent field trip to Rote (Pulau Rote; Roti) Island involving these authors has confirmed that two morphologically distinct forms of Chelodina exist there; leading here to a formal description and diagnosis of Chelodina mccordi roteensis ssp. nov. from eastern Rote Island, Indonesia.

Web: www.wb2020.qld.gov.au/icm/mrccc/main.htm Abstract The banks of the Mary River and its tributaries were once covered with rainforest species that protected the banks from erosion during floods. However these streams have generally become wider and shallower as a result of clearing, with many banks actively eroding, destroying valuable ecosystems and river flats in the process. The Mary Catchment has been identified in studies as an aquatic biodiversity hotspot and contains a number of endemic endangered species. Over the past decade, millions of dollars in government funding for river restoration has helped landholders and other interested community members to establish programs for restoration of the Mary River catchment. In 2004, the Mary River community was awarded the coveted National Rivercare Award. Now legislative and policy changes empowering the State Government and water corporations to capture, store and transfer large quantities of water out of the catchment into the proposed South East Queensland water grid, place these successful restoration activities and the community that has participated since 1995 at risk. This paper describes restoration works conducted in the Mary Catchment, and outlines the present and future impacts of the Traveston Crossing Dam proposal on the catchment, the restoration projects and communities. Keywords Traveston Crossing, endangered species, Ramsar wetlands Introduction South East Queensland is one of the fastest growing areas in Australia.

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.
