Numerical cladistic and phenetic analyses were undertaken on morphometric data from 22 Western Australian populations of the southern Australian shrub Boronia inornata and from the southern Western Australian tree Eucalyptus diptera and its unnamed allies. The E. diptera species complex includes four taxa, three of which are at present unnamed. These species are largely allopatric, although in one location the ranges of two species overlap. Two subspecies of Boronia inornata are described and one of them, subsp. leptophylla, contains three informal variants. Subsp. inornata and two of the variants of subsp. leptophylla are restricted to Western Australia. One variant of subsp. leptophylla is sympatric with subsp. inornata in Western Australia and also occurs in southern South Australia. The events which gave rise to the four species of the E. diptera complex and to the subspecies and variants of B. inornata occurred within the semiarid mallee zone of Western Australia, probably during the Quaternary. Speciation has occurred in a replacement pattern across the southern transitional rainfall zone, which is reflected in at least one other, unrelated taxon.

Cryptes utzoni Lin, Kondo & Cook sp. n. (Hemiptera: Coccidae) is described based on adult female morphology and DNA sequences from mitochondrial and nuclear loci. This Australian endemic species was found on the stem of Acacia aneura (Fabaceae) in Western Australia. All phylogenetic analyses of three independent DNA loci show that C. utzoni is closely related to C. baccatus (Maskell), the type and only species of Cryptes Maskell, 1892. The adult female of C. utzoni is described and illustrated and a table is provided of the characters that differ among adult females of the two species of Cryptes now recognised (C. baccatus and C. utzoni) and a morphologically similar Western Australian species, Austrolichtensia hakearum (Fuller). There is deep genetic divergence in COI among samples of C. baccatus, suggesting the possibility of a species complex in this taxon.

An account is given of the environmental features. the intertidal ecology. and the biogeographical relationships of the coast of the State of South Australia . The central and western coasts of South Australia are similar ecologically in comparable areas . In the supralittoral Melaraphe unifasciata (Gray) is dominant (except where conditions are very calm) and at high levels on very exposed coasts Calothrix fasciculata C. Agardh is found. The littoral zone where the coast is most exposed consists of barnacles-Chamaesipho in the upper littoral, Catophragmus in the mid littoral, and Balanus in the lower littoral-but where the coast is more sheltered it consists of molluscs in the upper and mid littoral and algae (Corallina, Gelidium, or Hormosira) in the lower littoral. In the upper sublittoral fucoid algae or in calm regions marine angiosperms are dominant. The south-east coast, however, differs in some respects from the central and west coasts. The number of barnacles found in the littoral zone is much reduced and the giant brown algae, Durvillea potatorum Areschoug and Macrocystis angustifolia Bory, are dominant in the upper sublittoral. This is associated with slightly lower sea temperatures. Sheltered coasts are more prominent in South Australia than in the eastern States of Australia. These include the shores of Spencer and St. Vincent Gulfs, the northern shores of Kangaroo I., and a number of scattered bays. The similarities between the coasts of South Australia and Victoria (Bennett and Pope 1953) are greater than the differences. Consequently the proposal of Bennett and Pope to recognize the Victorian and Tasmanian coasts as the Maugean Biogeographical Provinoe and the South Australian and the south-west Western Australian coasts as the Flindersian Province appears to be unjustified. It is suggested that the Naugean is best regarded as a subprovince with the Flindersian. The latter includes most of the coast of southern Australia. Considerable differences are noticeable between the organisms which inhabit the rocky coast of South Australia and the south coast of Western Australia. The available evidence indicates that a transition from the Flindersian to the tropical Dampierian Province occurs along the south and west coasts of Western Australia. The terms "Indo-Australian Province" and "Baudinian Province" have been proposed by previous authors to describe this transitional region. The Flindersian Province appears to be intermediate between cold-temperate and warm-temperate regions, becoming distinctly cool-temperate in Tasmania. It is relatively distinct from the warm-temperate Peronian Province of the coast of New South Wales.

Knowledge of the distribution and biology in Western Australia of species of Coptotermes has been very incomplete and in some respects erroneous, due partly to a lack of collecting and partly to the fact that the genus is notoriously difficult taxonomically. This genus, which includes the most destructive Australian termites, is represented in the State by four species and one subspecies. The form raffrayi previously thought to be a good species occurring sympatrically with acinaciformis is shown to be a subspecies of the latter form intergrading with it through a wide zone of intermediate forms and replacing it geographically in the wetter south-western corner of the State. C. michaelseni is restricted to south-western Australia and previous records from South Australia, Victoria, and Queensland are shown or considered to be misidentifications of C. frenchi. C. frenchi is definitely recorded from Western Australia for the first time. The separation of these two species by microscopical measurements is discussed. The fourth species is the recently discovered and described C. brunneus. The known Western Australian distributions of all species except C. brunneus are given. New biological data for all species are recorded, particularly on tree species attacked, dispersal of alates, and construction of mounds. C. acinaciformis builds symmetrical domed mounds in parts of southern Western Australia. Mound nests had not previously been recorded in 'the State and they differ considerably in construction from those recorded from the Northern Territory and north Queensland. C. frenchi is here definitely recorded as a mound builder. The mound-building habit erroneously attributed in the literature to C. michaelseni is shown to be due to the confusion of this species with frenchi. Photographs of mounds of C. acinaciformis raffrayi, C. frenchi, and C. brunneus are published for the first time.

Crested terns breeding in the Fremantle area of south-western Australia nest over an 8-month period, from early April to early November. However, laying is markedly bimodal, with subseasons in autumn and spring. Observations of individually marked breeding crested terns indicated a sedentary population utilizing a number of alternative, traditional colony sites all of which were within the study area. Individual crested terns tended to lay in the same part of the season as in the previous year. Colonies made up of terns with similarly phased reproductive cycles formed at different times within the protracted laying period. Individuals completed only one nesting cycle within a season, remaining in breeding condition for approximately 11-13 weeks. Breeding cycles were broadly circannual but potentially sub-annual. Despite superficial similarities at the populational level, this laying pattern differs markedly from that recorded for the silver gull in the same area. The pattern of breeding shown by crested terns therefore provides a second model to explain the double-nesting phenomenon observed in a number of seabird species on the western Australian coastline.

The brush-tailed possum (T. vulpecula) from Western Australia was found to be nearly 150 times more resistant to fiuoroacetate intoxication in vivo than the same species from South Australia. Acetone powder preparations from the liver of animals from both populations showed similar abilities to convert fiuoroacetate into fiuorocitrate. Aconitate hydratase activity in liver preparations from both Western Australian and South Australian animals was similarly and competitively inhibited by fiuorocitrate. Both animals were capable of defiuorinating fiuoroacetate at similar rates by a glutathione-dependent enzymic mechanism resulting in the formation of free fiuoride ion and S-carboxymethylcysteine. Glutathione was also capable of partial protection against the toxic effects of fiuoroacetate in vitro by a further unelucidated mechanism.

A morphological review of the diminutive annual species from the Stylidium despectum R.Br. group (Stylidiaceae) is presented. Twelve species are recognised, of which 10 are endemic in the south-west of Western Australia and two are widespread across southern temperate Australia. Following examination of type material, herbarium collections and field observations, a change of circumscription is presented for S. despectum and S. inundatum R.Br. The former name is applied to a widespread species that occurs in Western Australia, South Australia, Victoria, New South Wales and Tasmania, and is characterised by scattered or rosetted leaves, pink and/or white corolla lobes in a fan-shaped arrangement, and an immobile floral column. S. brachyphyllum Sond. is newly placed into synonymy under S. despectum and a lectotype selected. S. inundatum is redefined as a south-western Australian endemic with scattered leaves, vertically-paired or evenly spreading corolla lobes, and a mobile floral column. A lectotype is designated for S. inundatum, and S. sidjamesii Lowrie & Kenneally is treated as conspecific. S. beaugleholei J.H.Willis is confirmed for Western Australia, South Australia, Victoria and Tasmania. S. asymmetricum Wege, a new and apparently rare species from the Northern Jarrah Forest in south-western Australia, is formally described and revised descriptions are provided for S. longitubum Benth., S. pygmaeum R.Br., S. rhipidium F.L.Erickson & J.H.Willis, S. roseoalatum F.L.Erickson & J.H.Willis, S. roseonanum Carlquist, S. tinkeri Lowrie & Kenneally, S. utricularioides Benth. and S. xanthopis F.L.Erickson & J.H.Willis. A lectotype is designated for S. longitubum Benth. and S. utricularioides var. rosulatum Mildbr. is newly placed into synonymy under S. roseoalatum. A key to species is provided, along with photographs to aid identification. Further field-based studies are required to refine the taxonomy of this group and to better understand the distribution, rarity and conservation status of some of the taxa. In Western Australia, seven species are listed as being of conservation concern, of which S. asymmetricum, S. tinkeri and S. xanthopis require immediate further survey to ascertain whether they should be given Threatened Flora status.

Fossils from the Eocene of South Australia and Western Australia and the Oligo–Miocene of Victoria represent the first known Australian leaf fossils of subfamily Persoonioideae, tribe Persoonieae. Persoonieaephyllum blackburnii sp. nov. is described from Middle Eocene Nelly Creek sediments near Lake Eyre, South Australia. Persoonieae are an important clade for understanding vegetation transitions in Australasia. The Nelly Creek leaf fossils are small (~6mm wide) and belong to an assemblage that has some characteristics of open vegetation, which is also inferred for the Oligo–Miocene of the Latrobe Valley, Victoria. In contrast, the Western Australian Late Eocene Persoonieae occur with diverse Lauraceae and other elements now typical of closed rainforests, and may, therefore, have been derived from communities that are unlike those in which most Persoonieae now occur. All fossil Persoonieae leaves so far known are hypostomatic (or virtually so), a state of stomatal distribution now only found in species of reasonably mesic habitats in New Zealand, New Caledonia and eastern Australian eucalypt forests. The ancestral state of stomatal distribution in Persoonieae leaves is unclear, but evidence suggests ancient associations of amphistomaty with open habitats, evolutionary loss of adaxial stomata in more closed vegetation, and the evolution of pronounced xerophylly within south-western Australian heathlands.

P.-Cambridge, 1870), are re-illustrated and re-diagnosed, and complementary molecular data for 14 species and seven genes are analysed with Bayesian methods. Members of thenigrum-group are of long-standing conservation significance, andI.nigrumis the only spider in Australia to be afforded threatened species status under both State and Commonwealth legislation. Two other species,I.formosumRix & Harvey,sp. n.andI.kopejtkaorumRix & Harvey,sp. n., are also formally listed as Endangered under Western Australian State legislation. Here we significantly relimitI.nigrumto include only those populations from the central and central-western Wheatbelt bioregion, and further document the known diversity and conservation status of all known species.

The trapdoor spider family Migidae has a classical Gondwanan distribution and is found on all southern continents except the Indian region. The Australian fauna consists of three genera including Moggridgea O. P. Cambridge from south-western Australia and Kangaroo Island, South Australia; Moggridgea is otherwise widespread throughout Africa. The sole named species of Moggridgea from Western Australia, M. tingle Main, and its unnamed relatives are the subject of the present paper, which was stimulated by concern for the long-term persistence of populations, and the discovery of deep genetic divergences between populations. A phylogeny of the Western Australian species relative to African and South Australian Moggridgea was generated using molecular COI and ITS rDNA data, and based on both molecular and morphological criteria we conclude that the Western Australian taxa should be removed from Moggridgea and transferred to a new genus, Bertmainius. The seven species are delimited using both morphological and molecular criteria: B. tingle (Main) (the type species), and six new species, B. colonus, B. monachus, B. mysticus, B. opimus, B. pandus and B. tumidus. All seven species are considered to be threatened using IUCN criteria, with the major threatening processes being inappropriate fire regimes and climate change.

Christian missionaries played an important role in the Australian nation building that started in the nineteenth century. This essay explores the multifaceted and complex cultural encounters in the context of two aboriginal missions in Australia in the nineteenth century. More specifically, the essay explores the New Norcia mission in Western Australia in 1846-1900 and the Lutheran mission in South Australia in 1838-1853. The essay begins with an overview of the history of the two missions followed by a discussion of the key faces of the cultural encounters that occurred in the course of the missions. This is followed by theological reflections on the encounters in dialogue with contemporary theology, particularly the works of Robert Schreiter.
