Full textAbstract:
A list of 37 species of ptyctimous mites from the State of Victoria, Australia, is provided. Seven species new for science are described and further seven are recorded for the first time in Victoria. The genus Arphthicarus has been discovered in Victoria and is represented by two new species. Zoogeographical distribution of each species is provided. Analysis of the ptyctimous fauna from four Victorian areas (Otway Ranges, Yarra Ranges, Errinundra Plateau and Strzelecki Ranges) has revealed that four species occur in a large number of specimens in one of the areas. Similarity analyses indicate that the faunas of Errinundra Plateau and Yarra Ranges are the most similar. An overview of state of knowledge on the ptyctimous mites from State of Victoria, Australia and Australasian Region is presented.

The rate and spatial scale at which natural environments are being modified by human land-uses mean that a regional or national perspective is necessary to understand the status of the native biota. Here, we outline a landscape-based approach for using data from the ‘New Atlas of Australian Birds’ to examine the distribution and status of avifauna at a regional scale. We use data from two bioregions in south-east Australia – the Gippsland Plain and the Strzelecki Ranges (collectively termed the greater Gippsland Plains) – to demonstrate this approach. Records were compiled for 57 landscape units, each 10′ latitude by 10′ longitude (~270 km2) across the study region. A total of 165 terrestrial bird species was recorded from 1870 ‘area searches’, with a further 24 species added from incidental observations and other surveys. Of these, 108 species were considered ‘typical’ of the greater Gippsland Plain in that they currently or historically occur regularly in the study region. An index of species ‘occurrence’, combining reporting rate and breadth of distribution, was used to identify rare, common, widespread and restricted species. Ordination of the dataset highlighted assemblages of birds that had similar spatial distributions. A complementarity analysis identified a subset of 14 landscape units that together contained records from at least three different landscape units for each of the 108 ‘typical’ species. When compared with the 40 most common ‘typical’ species, the 40 least common species were more likely to be forest specialists, nest on the ground and, owing to the prevalence of raptors in the least common group, take prey on the wing. The future status of the terrestrial avifauna of the greater Gippsland Plains will depend on the extent to which effective restoration actions can be undertaken to ensure adequate representation of habitats for all species, especially for the large number of species of conservation concern.

Abstract This study considered the degree of genetic variation for diameter (DBH), basic density (BD), predicted pulp yield (PPY), fibre length (FL), microfibril angle (MFA) and cellulose content (CC) amongst eight subraces of Eucalyptus globulus growing in a field trial in NW Tasmania. There were significant subrace effects for BD, FL and CC. This variation affected the relative profitability of the subraces for pulp production. On average, the most profitable subraces (on NPV/ha over the base population mean) were Strzelecki Ranges ($862.04), Western Otways ($657.80) and Strzelecki Foothills ($576.81). The genetic control (heritability) of variation in DBH, FL and MFA was moderate (0.15 < h2< 0.27), while control for BD, PPY and CC was high (h2> 0.40). Genetic correlations between growth and wood properties were not statistically significant, except for DBHMFA (-0.86). Most genetic correlations amongst wood properties were outside the parametric space (< -1 or >1), but there were significant correlations between BDMFA (-0.70) and PPY-CC (0.82). The empirical response to selection on an index based on a pulp wood objective (which included volume and basic density) resulted in a gain of 4.3% for DBH, 7.9% for BD and marginal changes for all other traits, with a net impact in profit of $1,270/ha. However, future profit calculations will need to consider the effect of FL, MFA and CC on the economics of wood processing to fully evaluate the economic impact of breeding.

"Identification of key environmental variables associated with the presence of Toothed Leionema (Leionema bilobum serrulatum) in the Strzelecki Ranges, Victoria, Australia." Australian Journal of Botany 59, no. 3 (2011): 207. http://dx.doi.org/10.1071/bt10197.
Full textAbstract:
Toothed Leionema is one of four subspecies of Leionema bilobum from the Rutaceae family. A dense shrub or small tree, growing to ~4 m high, it is a poorly investigated species which is considered rare in Victoria, Australia. This paper presents the results of a study using Geographical Information Systems and Weights-of-Evidence predictive modelling to assess the importance of seven environmental factors in determining habitat suitability for this species in the Strzelecki Ranges, Victoria. This method is particularly useful in understanding the distribution of rare species, especially where the ecology of the species of interest is not well understood. Of the seven environmental factors considered here, four were found to be important: elevation, aspect, distance to water and distance to plantation (disturbed) areas. The modelling results indicate that areas with elevations between 350 and 550 m and a dominant south-western aspect that are close to plantation areas (within 700 m), and to water (within 1100–1200 m), provide potentially suitable habitat for Toothed Leionema in the region.

Full textAbstract:
The nesting requirements of the yellow-tailed black-cockatoo (Calyptorhynchus funereus) were studied at 68 sites in Eucalyptus regnans forest in the Strzelecki Ranges, South Gippsland, Victoria. Nest trees were located and their characteristics related to forest stand variables. Eighteen nest hollows were found. Nest trees had a mean diameter at breast height of 2.5 m, a mean estimated age of 221 years, a mean height of 58 m and for live nest trees a mean crown diameter of 22 m. The currently proposed rotation time for silvicultural systems of 80-150 years will reduce the number of hollow-bearing trees suitable for nesting yellow-tailed black-cockatoos. Adequate numbers of trees must be retained in logged areas and wildlife corridors and reserves, and protected to ensure a continual supply for yellow-tailed black-cockatoos and other hollow-dependent species. If agonistic behaviour is operating between female yellow-tailed black-cockatoos, nesting potential may be enhanced if trees retained on coupes are evenly distributed rather than clumped. Silvicultural systems that facilitate the protection of trees retained on coupes would benefit the conservation of the yellow-tailed black-cockatoo.

Full textAbstract:
Variation in seedling abnormalities and 2- and 4-year growth were studied in a trial in north-westem Tasmania established from 594 open-pollinated families from throughout the geographical range of Eucalyptus globulus Labill. ssp, globulus and populations intergrading with other subspecies. Most (77-80%) of the total (phenotypic) variation in growth traits occurred within families. The genetic variation between families within localities (within c. 10 krn; 13-15% of the total variation), between localities within regions (within c. 100-150 km; c: 4%) and between regions (3-8%) was generally highly significant. However, regional and locality components together accounted for only a small proportion of the total phenotypic variation. Little differentiation was detected between separate sampling sites within localities. Estimates of individual narrow-sense heritabilities were markedly higher than previous reports and were 0.38 for conic volume and 0.41 for height at 4 years, assuming a coefficient of relatedness of 0.4 amongst open-pollinated sibs. On average, progenies from the Otway Ranges region were the fastest growing at the test site, followed by those from King Island. Parent trees with high breeding values were concentrated in the Otway Ranges, Strzelecki Ranges and far southeastem Tasmania with the Bass Strait island localities having intermediate frequencies. Forest fragmentation through clearing for agriculture appears to have had a deleterious effect on the quantitative genetic structure of intergrade populations consistent with high levels of inbreeding. Remnant populations tended to have higher levels of severely abnormal seedlings, higher mortality and poorer growth, and higher heritability estimates and variability both within and between families. Advanced generation hybridisation and inbreeding due to long periods of isolation in small, relict populations may also have had similar effects. Populations sampled are, therefore, likely to have markedly different levels of inbreeding which may have inflated differences between localities and may have important consequences for the exploitation of this material for breeding.

Cooper, G. T. "SEISMIC STRUCTURE AND EXTENSIONAL DEVELOPMENT OF THE EASTERN OTWAY BASIN-TORQUAY EMBAYMENT." APPEA Journal 35, no. 1 (1995): 436. http://dx.doi.org/10.1071/aj94028.
Full textAbstract:
The Eastern Otway Basin exhibits two near-or-thogonal structural grains, specifically NE-SW and WNW-ESE trending structures dominating the Otway Ranges, Colac Trough and Torquay Embayment. The relative timing of these structures is poorly constrained, but dip analysis data from offshore seismic lines in the Torquay Embayment show that two distinct structural provinces developed during two separate extensional episodes.The Snail Terrace comprises the southern structural province of the Torquay Embayment and is characterised by the WNW-ESE trending basin margin fault and a number of small scale NW-SE trending faults. The Torquay Basin Deep makes up the northern structural province and is characterised by the large scale, cuspate Snail Fault which trends ENE-WSW with a number of smaller NE-SW trending faults present.Dip analysis of basement trends shows a bimodal population in the Torquay Embayment. The Snail Terrace data show extension towards the SSW (193°), but this trend changes abruptly to the NE across a hinge zone. Dip data in the Torquay Basin Deep and regions north of the hinge zone show extension towards the SSE (150°). Overall the data show the dominance of SSE extension with a mean vector of 166°.Seismic data show significant growth of the Crayfish Group on the Snail Terrace and a lesser growth rate in the Torquay Basin Deep. Dip data from the Snail Terrace are therefore inferred to represent the direction of basement rotation during the first phase of continental extension oriented towards the SSW during the Berriasian-Barremian? (146-125 Ma). During this phase the basin margin fault formed as well as NE-SW trending ?transtensional structures in the Otway Ranges and Colac Trough, probably related to Palaeozoic features.Substantial growth along the Snail Fault during the Aptian-Albian? suggests that a second phase of extension affected the area. The Colac Trough, Otway Ranges, Torquay Embayment and Strzelecki Ranges were significantly influenced by this Bassian phase of SSE extension which probably persisted during the Aptian-Albian? (125-97 Ma). This phase of extension had little effect in the western Otway Basin, west of the Sorrel Fault Zone, and was largely concentrated in areas within the northern failed Bass Strait Rift. During the mid-Cretaceous parts of the southern margin were subjected to uplift and erosion. Apatite fission track and vitrinite reflectance analyses show elevated palaeotemperatures associated with uplift east of the Sorell Fault Zone.

Abstract Low and variable capsule and seed set is a major factor limiting seed production in Eucalyptus globulus seed orchards. This study identified the relative contribution of the maternal and paternal parent to reproductive success in E. globulus, and examined the genetic basis to the observed variation. Reproductive success was measured in terms of the number of viable seeds obtained per flower crossed. Data on the reproductive success of numerous genotypes from the Furneaux, Strzelecki Ranges and Otways races were obtained from: (i) 12 years of operational full-sib crossing; (ii) a designed fullsib diallel mating scheme; and (iii) capsule retention trials conducted over three seasons at two Tasmanian seed orchards on the same ramets of different genotypes. Analysis of the sparse operational data revealed that both male and female factors significantly affected reproductive success, accounting for 5.0% and 7.9% of the variation respectively. The more precise diallel crossing revealed that a large, and significant, proportion 55%, of the variation in reproductive success between crosses at a single site was explained by the female parent. The male parent explained only 6.7%, but this effect was not statistically significant and was related to variation in in vitro pollen germination. The significant female effect was found to be consistent at the genotype level across seasons, sites and pollination techniques suggesting a genetic basis to the variation. It is argued that selection of genetically fecund females is a key consideration in reducing costs of manual pollination for breeding and deployment purposes.

Full textAbstract:
The influence of Neogene tectonics in the SE Australian basins has generally been underestimated in the petroleum exploration literature. However, onshore stratigraphic and offshore seismic data indicates that significant deformation and exhumation (up to one km or more) has occurred during the late Tertiary-Quaternary. This tectonism coincides with a change in the dynamics of the Australian plate, beginning at around 12 Ma, resulting in a WNW–ESE compressional regime which has continued to the present day.Significant late Miocene tectonism is indicated by a regional angular unconformity at around the Mio-Pliocene boundary in the onshore and nearshore successions of the SE Australian basins.Evidence of on going Pliocene- Quaternary tectonism is widespread in all of the SE Australian basins. Late Tertiary tectonism has produced structures in the offshore SE Australian basins which have been favourable targets for petroleum accumulation (e.g. Nerita structure, Torquay Sub-basin; Cormorant structure, Bass Basin). In the offshore Gippsland Basin, most of the oil- and gas-bearing structures have grown during Oligocene-Recent time. Some Gippsland Basin structures were largely produced prior to the mid- Miocene, while others have a younger structural history. In areas of intense late Tertiary exhumation and uplift (e.g. proximal to the Otway and Strzelecki Ranges), burial/maturation models of petroleum generation may be significantly affected by Neogene uplift.Many structures produced by late Miocene-Pliocene deformation are dry. These relatively young structures may post-date the major maturation episodes, with the post-structure history of the basins dominated by exhumation and cooling.

Full textAbstract:
The distribution, habitat and conservation status of Notomys fuscus were determined by collating past records of the species and conducting field investigations covering areas of historical distribution and similar habitats. Detailed population sampling was carried out in two geographically distinct locations where populations appeared to be extant. Evidence of N. fuscus was found throughout the Strzelecki Desert east and south of the Strzelecki Creek in South Australia and in an isolated group of dunes south-east of the Diamantina River in south-west Queensland. Populations were located in a variety of sand dune habitats (excepting those dominated by Triodia) throughout these areas, implying that the species is a habitat-generalist with a preference for a sandy substrate. Eight floristic groups were identified from the 66 sites sampled, three of which supported N. fuscus populations. These ranged from extremely degraded dune and sand plain systems in the southern Strzelecki Desert, supporting mostly ephemeral plants, to well-vegetated dunes covered by sandhill canegrass,Zygochloa paradoxa, in south-west Queensland. However, the results suggest that the presence of consolidated dunes and perennial vegetation are important for the maintenance of stable populations. Relatively dense populations of N. fuscus were recorded only in the vicinity of major drainage systems. It is hypothesised that the higher nutrient status of the soils surrounding such systems may be an important factor affecting the distribution of N. fuscus. The study reaffirmed the species’ decline since European settlement of Australia, and recommends that the present vulnerable status of the species (IUCN Species Survival Commission (SSC) Rodent Specialist Group) be maintained.

Full textAbstract:
The intensive nature of land uses in the Strzelecki Ranges poses significant threats to landscape values and water quality. A comprehensive catchment strategy was developed based on sustainability science concepts incorporating the careful management of landscape values, proper land management approaches, and government policy and legislative change to ensure that agriculture, forestry and other land uses become sustainable in this sensitive environment. The readily measurable water quality indicators of turbidity, flow, electrical conductivity, and water temperature were used to determine the impacts of the major land uses in the Strzeleckis. From a water quality perspective, there was a trend of decreasing water quality with increasing intensity in land management. However, from a total sediment load perspective, the forest area contributed the highest total sediment load due to higher volumes of steam flow suggesting that natural processes in the Strzeleckis may remain the principal mechanisms for sediment movement within the catchment. An incidental but significant finding was extensive bioturbation along the riparian zone of the plantation area, the extent of which was not observed in the other catchments. This finding suggested that bioturbation may have been the most significant contributor to poorer water quality flowing from in the plantation catchment. The project developed insights into the major environmental processes active in the upper catchment of the Morwell River. Understanding of the contributions to total sediment loads from natural erosional processes and bioturbation, findings related to the impacts on water quality from agricultural practices, and encountering negligible impacts from conservative timber harvesting practices demonstrate that catchment management approaches need to be tailored to achieve sustainability in land uses across the landscape. Key recommendations include the re-establishment and protection of riparian zones in agricultural catchments, the careful assessment and setting of stream buffer zone widths for timber harvesting operations, and the need for further work to map the extent of natural processes such as bioturbation and stream bank erosion. To mitigate these issues, government policy and legislation will need to focus on the preservation and enhancement of the Crown land riparian zones. Recommended changes to current administrative land management arrangements for these sensitive areas include a move from licensing riparian zones for agricultural practices such as grazing to conservation.

Finding Australian Birds is a guide to the special birds found across Australia's vastly varied landscapes. From the eastern rainforests to central deserts, Australia is home to some 900 species of birds. This book covers over 400 Australian bird watching sites conveniently grouped into the best birding areas, from one end of the country to the other. This includes areas such as Kakadu in the Top End and rocky gorges in the central deserts of the Northern Territory, the Great Barrier Reef in Queensland, rainforests distributed along the eastern Australian seaboard, some of the world's tallest forests in Tasmania, the Flinders Ranges and deserts along the iconic Strzelecki and Birdsville Tracks in South Australia, and the mallee temperate woodlands and spectacular coastlines in both Victoria and south west Western Australia.
Each chapter begins with a brief description of the location, followed by a section on where to find the birds, which describes specific birdwatching sites within the location's boundaries, and information on accommodation and facilities. The book also provides a comprehensive 'Bird Finding Guide', listing all of Australia's birds with details on their abundance and where exactly to see them.
Of value to both Australian birdwatchers and international visitors, this book will assist novices, birders of intermediate skill and keen 'twitchers' to find any Australian species.
