A: Because he was a little shellfish! Synopsis The overall aim of this project was to consider several freshwater invertebrates that are restricted both geographically and climatically to determine their population genetic structure, population distribution and population viability. The study was set in a framework of genetic analysis as genetics can be used to answer a whole suite of conservation focused questions. Specifically, the study concentrated on the population dynamics of three freshwater crayfish from the genus Euastacus: E. hystricosus, E. urospinosus and E. robertsi. Also, in this study I explored the role of two commensal flatworms as proxy species, to aid in disentangling the population structure of their crayfish hosts. These flatworms were Temnosewellia batiola, which is specific to E. hystricosus and Temnosewellia albata, which is specific to E.

(;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.

While recent evolutionary studies have focused on a few of these species, here we provide a comprehensive phylogenetic estimate of relationships among the species within the genus. We sequenced three mitochondrial gene regions (COI, 16S, and 12S) and one nuclear region (28S) from 40 species of the genus Euastacus, as well as one undescribed species. Using these data, we estimated the phylogenetic relationships within the genus using maximum-likelihood, parsimony, and Bayesian Markov Chain Monte Carlo analyses. Using Bayes factors to test diVerent model hypotheses, we found that the best phylogeny supports monophyletic groupings of all but two recognized species and suggests a widespread ancestor that diverged by vicariance.

  • (Decapoda: Parastacidae: Euastacus) from Northeastern New South Wales, Australia
    © Copyright Australian Museum, 2005 Records of the Australian Museum (2005) Vol. 57: 361–374. ISSN 0067-1975 New Crayfishes (Decapoda: Parastacidae: Euastacus) from Northeastern New South Wales, Australia JASON COUGHRAN School of Environmental Science and Management, Southern Cross University, Lismore NSW 2480, Australia [email protected] ABSTRACT. Routine astacological surveys in northeastern New South Wales have revealed four new species of crayfish. Three species are allied to the “setosus complex”, a group of small and poorly spinose Euastacus previously recorded only from Queensland: E. girurmulayn n.sp. from the Nightcap Range, E. guruhgi n.sp. from the Tweed volcanic plug and E. jagabar n.sp. from the Border Ranges. These three species are differentiated chiefly on features of the sternal keel, spination and antennal squame. Euastacus dalagarbe n.sp., recorded from the Border Ranges, has affinities with a growing group of crayfish displaying morphological traits intermediary between the setosus complex and more characteristically spinose Euastacus. It differs markedly in spination of the chelae, and in the nature of the lateral processes of the pereiopods. All of these taxa occur in association with the much larger and more spinose E. sulcatus. An unusual crayfish specimen of uncertain status is also discussed. COUGHRAN, JASON, 2005. New crayfishes (Decapoda: Parastacidae: Euastacus) from northeastern New South Wales, Australia. Records of the Australian Museum 57(3): 361–374. Recent taxonomic revision of the genus Euastacus (Morgan, distinct from the setosus complex, being medium to large in 1986, 1988, 1997) resulted in both the description of several size and of moderate to strong spination.

Comparing populations in fished and non-fished areas can provide information that is vital for the management and protection of species. We conducted field surveys ofEuastacus armatus in non-fished and fished reservoirs and provide comparisons with a heavily fished area of the River Murray. The non-fished population (Talbingo Reservoir) ofE. armatus exhibited almost equal sex ratios, robust normally-distributed population structure and a high proportion of mature and berried females. The parameters defining two fished populations (Blowering Reservoir and the River Murray) deviated significantly, to varying degrees, from the benchmark population (Talbingo). These differences suggest that recreational fishing may impose a considerable impact on the population parameters of E. armatus. Comparison with the benchmark defined in the present study will allow tracking of the population recovery under the new fishing regulations forE. armatus in the southern Murray-Darling Basin.

  • Biology of the Mountain Crayfish Euastacus Sulcatus Riek, 1951 (Crustacea: Parastacidae), in New South Wales, Australia

Crayfish surveys were undertaken at 245 regional sites between 2001 and 2005, and the species was recorded at 27 sites in the Clarence, Richmond and Tweed River drainages of New South Wales, including the only three historic sites of record in the state, Brindle Creek, Mount Warning and Richmond Range. The species was restricted to highland, forested sites (220–890 m above sea level), primarily in national park and state forest reserves. Adult crayfish disappear from the observable population during the cooler months, re-emerging in October when the reproductive season commences. Females mature at approximately 50mm OCL, and all mature females engage in breeding during a mass spawning season in spring, carrying 45–600 eggs. Eggs take six to seven weeks to develop, and the hatched juveniles remain within the clutch for a further 2.5 weeks. This reproductive cycle is relatively short, and represents a more protracted and later breeding season than has been inferred for the species in Queensland. A combination of infrequent moulting and small moult increments indicated an exceptionally slow growth rate; large animals could feasibly be 40–50 years old.

The listing of Endangered Species is provided for by Part 7A, Division 2 of the Act. The Fisheries Scientific Committee, with reference to the criteria relevant to this species, prescribed by Part 16 of the Fisheries Management (General) Regulation 2010 (the Regulation) has found that: Background 1) Euastacus dharawalus (Morgan, 1997), is a valid recognised taxon and is a species as defined in the Act. The species is endemic to Wildes Meadow Creek (Shoalhaven catchment) and is restricted to that part of the waterway upstream of Fitzroy Falls (a total of ~12 km of waterway with mean daily flow > 5 ML d-1). Of this, only 1 km is of high quality habitat protected within Morton National Park, 3.2 km has been inundated by Fitzroy Falls Reservoir and the remainder is within agricultural land. Existing data (McCormack, unpublished data) suggests that the extent of occurrence is estimated to be <0.1 km2. 2) Euastacus dharawalus represents a monophyletic group within the southern clade of Euastacus species, with the closest related species being Euastacus claytoni, Euastacus brachythorax, Euastacus guwinus and Euastacus yanga (Baker et al., 2004; Shull et al., 2005).
