Shining Gum

The complete geographic range of Eucalyptus nitens s. lat. (shining gum) was sampled to determine the pattern of variation in adult and seedling morphology. Analyses of the different data sets indicated the presence of two distinct taxa: one, characterised by denticulate adult leaf margins, is described as E. denticulata sp. nov.; the other, characterised by entire leaf margins, is E. nitens s. str. Many other characters distinguish the two taxa. Mature trees of E. denticulata have leaves with higher oil gland density, longer peduncles, more cup-shaped rather than barrel-shaped fruit, more frequently exserted valves, and rounded and longer flower buds compared with E. nitens s. str. Seedlings of the two species can be distinguished mainly on the basis that those of E. denticulata have longer internodes and leaves which clasp the stem to a lesser extent. The major occurrence of E. denticulata is on the Errinundra Plateau, East Gippsland, with limited occurrences in the Baw Baw Ranges and Central Highlands of Victoria. Eucalyptus nitens s. str. is found in isolated stands in New South Wales and Victoria. The two species are allopatric, with the exception of the Baw Baw Ranges and Central Highlands of Victoria where some stands are mixed. Eucalyptus nitens s. str. is also geographically variable, comprising three distinct geographic races: northern and central New South Wales, southern New South Wales, and the Baw Baw Ranges and Central Highlands of Victoria.

Spousal Homicide

Frequencies of homicide victimization of wives and husbands, while cohabiting and when separated, are reported for all spousal homicides known to the police in Canada (1974-1990), in New South Wales, Australia (1968-1986), and in Chicago (1965-1990). In all three data sets, the degree to which spousal homicide victimization was female-biased was significantly greater when the couple were estranged than when they were coresiding. Victim counts and population-at-large estimates of coresiding and separated nowmarried spouses were combined to estimate differential homicide rates incurred by coresiding and estranged married persons. Wives in all three countries incurred substantially elevated risk when separated as compared to when coresiding.

PurposePeople with intellectual disability (ID) experience high rates of physical and mental health problems, while access to appropriate healthcare is often poor. This cohort was established to develop an epidemiological profile related to the health, health service use, disability services, mortality and corrective services records of people with ID.ParticipantsThe cohort contains 92 542 people with ID (40% females) with a median age of 23 years (IQR: 12–43 years) and 2 004 475 people with a neuropsychiatric or developmental disorder diagnosis (50% females) with a median age of 51 years (IQR: 29–73 years) from New South Wales, Australia. The whole sample contains records for 2 097 017 individuals with most data sets spanning financial years 1 July 2001 to 30 June 2016. A wide range of data from linked population data sets are included in the areas of disability, health, corrective services and targeted specialist support services in public schools, Public Guardian and Ombudsman services.Findings to dateThis study includes one of the largest cohorts of people with ID internationally. Our data have shown that the presence of ID is significantly associated with emergency department presentations and psychiatric readmissions after the first psychiatric admission based on a subcohort of people with a psychiatric admission. Adults with ID experience premature mortality and over-representation of potentially avoidable deaths compared with the general population.Future plansWithin the health service system, we will examine different components, that is, inpatient, emergency adult services, children and younger people services and costs associated with healthcare as well as mortality, cause and predictors of death. The neuropsychiatric and developmental disorders comparison cohort allows comparisons of the physical health, mental health and service use profiles of people with ID and those with other neuropsychiatric disorders.

Observation Period

In a Belah - Rosewood woodland in western New South Wales, stocking with feral goats over a four year period effected changes in the composition of the tree and shrub component. The most readily browsed tree was Rosewood and mature trees of this species were stripped of foliage to a height of 2 m. At an early stage Desert broombush (Templetonia egena) and young Warrior bush (Apophyllum anomalum) were severely damaged and young Yarran (Acacia homalophylla) and Belah defoliated. Most defoliated Yarran died within the observation period. Two shrubs regarded as weed species, Punty bush (Cassia eremophila var. platypoda) and Desert cassia (C. eremophila var. coriacea) were heavily browsed in the third year and subsequently eliminated. The weed shrub Turpentine (Eremophila sturtizl was not browsed at any time.

Uncertainty in identifying Allocasuarina shrubs of the North Coast botanical region of New South Wales and south-eastern Queensland prompted investigation of species limits using morphological and cytological data. PATN analysis using 36 morphometric characters, seedling morphology and cytogenetic analysis supported the existing circumscription of A. defungens and A. simulans. Trees of A. littoralis were observed throughout the study area and the distinct morphology of the diploid and polyploid forms is noted. Further work is required to establish whether these differences are consistent over the full range of the species. Shrubby plants of A. sect. Cylindropitys, other than the above species, growing along the NSW North Coast are currently known by several names, including A. defungens×A. littoralis. These plants were found to be morphologically most similar to A. emuina and A. thalassoscopica from south-eastern Queensland and to have similar phenotypes. Allocasuarina thalassoscopica is recircumscribed on morphological characters to encompass these shrubby plants in New South Wales and A. emuina and A. thalassoscopica from south-eastern Queensland. A key is provided for identification of plants of A. sect. Cylindropitys. Counts of chromosomes found that recircumscribed A. thalassoscopica is tetraploid and A. defungens is triploid at Nabiac but tetraploid at Khappinghat Nature Reserve. The results of the present study are consistent with a hypothesis of parallel evolution, which is possibly due to edaphic factors and requires further study.

We investigated the composition and distribution of bird assemblages in the continuous Pilliga woodlands of north-west New South Wales in relation to floristic assemblages and disturbance (logging, fire and grazing) patterns. Box-ironbark woodlands contained high densities of White Cypress Pine Callitris glaucophylla and Narrow-leaved Ironbark Eucalyptus crebra, had a sparse, depauperate understorey, and were associated with frequent, intense logging and infrequent fires (due to fire exclusion and the use of grazing for fuel reduction). Box-ironbark woodlands were characterized by high frequencies of 12 bird species that occurred throughout the Pilliga and low frequencies of many other species. Blakely's Red Gum E. blakelyi woodlands typical of creeks and Broad-leaved Ironbark E. fibrosa woodlands typical of poor soils contained lower densities or smaller trees of C. glaucophylla and E. crebra, had a moderately dense, diverse understorey, and were associated with infrequent low-intensity logging and moderately frequent wildfire. Bird species assemblages of Broad-leaved Ironbark woodlands were similar to those of box-ironbark woodlands. Blakely's Red Gum woodlands were characterized by 36 bird species that were virtually absent from box-ironbark and Broad-leaved Ironbark woodlands, including 10 threatened and declining species. The 10 are among 48 woodland species that are known or thought to be declining and that are dependent on woodlands with mature trees and grassy or patchy grass/shrub understorey. We conclude that these species have declined in the Pilliga and will continue to decline under existing disturbance regimes, particularly in box-ironbark woodlands. We suggest adaptive management strategies for maintaining and rehabilitating their habitats.

AbstractThe effects of past glaciation in what is now Australian territory were first recognized on Macquarie Island, probably by David Ramsay, in 1821. The recognition by Darwin in 1836, and reporting by Milligan in 1848 of ice-transported pebbles and boulders in late Palaeozoic marine rocks in Tasmania, showed on the one hand participation in and on the other familiarity with the controversy in Great Britain at that time on the origin of erratics and drift currents. Reports by Clarke (1852), Daintree in 1859, Selwyn (1860), and Gould (1860) of the effects of land ice on Mount Koscuisko (New South Wales), Bacchus Marsh (Victoria), Inman Valley (South Australia), and the Central Highlands (Tasmania), respectively, reflect the increasing recognition in Great Britain of the erosional and depositional effects of glaciers. Daintree, Selwyn, and Gould were all closely connected with A.C. Ramsay, the main British protagonist of the glacial theory at the time, whereas David Ramsay and Milligan were probably influenced by Robert Jameson of Edinburgh.
