The species Diaptomus (Eodiaptomus) lumholtzi Sars and D. (Tropodiaptomus) australis (Kiefer) are redescribed and figured. Both species are recorded from numerous new localities in northern Australia. The southern limit of distribution of D. lumholtzi is discussed in relation to the northern limit of Boeckella. A single example of the coexistence of D. lumholtzi with Boeckella triarticulata, and three examples of coexistence of D. lumholtzi with Calamoecia are cited.

Abstract Results of a stratigraphic and tectonic study of the Mourotte syncline, Provence, France, divide the structure into three parts. The northern part is composed of Hauterivian littoral beds containing Danian dinosaur eggs. The Danian limestone-sandstone series disappears at La Neuve while the marly upper Danian beds continue to the extreme northern limit of the syncline. In the central part the Hauterivian wedges out, and toward its southern limit the substratum is entirely upper Jurassic. In the southern part, the Danian limestones are only visible on the northeast border. Bird eggs collected in the area assign the southern part of the syncline to the Thanetian. Overturning is less noticeable in the north, becoming acute toward the south where the syncline is tightly overturned.

The effects of climate change are becoming apparent in the biosphere. In the 20th century, South Korea experienced a 1.5 °C temperature increase due to rapid industrialization and urbanization. If the changes continue, it is predicted that approximately 15–37% of animal and plant species will be endangered after 2050. Because butterflies act as a good indicator for changes in the temperature, the distribution of butterflies can be used to determine their adaptability to climate patterns. Local meteorological data for the period 1938–2011 were used from the National Forest Research Institute of Korea. Local temperature data were additionally considered among the basic information, and the distribution patterns of butterflies were analyzed for both the southern and northern regions. Southern butterflies (with northern limit) tend to increase in number with significant correlation between the temperature and number of habitats (p < 0.000), while northern butterflies (with southern limit) show no statistical significance between the temperature and number of habitats, indicating their sensitivity to temperature change. This finding is in accordance with the conclusion that southern butterflies are more susceptible to climate change when adapting to local environments and expanding their original temperature range for survival, which leads to an increase in the numbers of their habitats.

A taxonomic treatment is presented for all Polygala L. species of northern Australia (north of 26°S). In total, 45 species are treated, of which 44 are native and 36 are endemic to Australia. Twenty-six new species and four new varieties are described. A key to all 50 Australian species is provided, including six introduced species (five of which are restricted to southern states of Australia and are not treated here in detail). Lectotypes are here designated for five names. Nomenclatural issues regarding P. linariifolia Willd., P. glaucoides L. and P. triflora L. are discussed.

Species belonging to the genus Laonice (Polychaeta: Spionidae) from continental shelf and slope depths off western and northern Australia are described. Three species are new to science (L. lemniscata, L. insolita, L. pectinata), two additional species of uncertain identity are recognised from incomplete material and are similar to existing species. A key is provided to allow identification of all six Laonice species known from Australia. Also, a new standard for the observation of hooded hooks in Laonice is established. One of the Australian species, L. quadridentata, belongs to a group of Laonice species with fused prostomium and peristomium. These species are of great morphological similarity and several are reported to exhibit ontogenetic and individual variability and we discuss the significant taxonomic problems that are a consequence of that variability. The faunas of the continental margin of western and northern Australia were poorly sampled prior to the extensive surveys that generated our study material; this study and other current work suggests that our present estimates of species richness of the Australian marine invertebrate fauna significantly underestimate species richness, perhaps by as much as 50%.

This is the first book to deal exclusively with the Australian members of the Family Ardeidae (herons, egrets and bitterns). It gives a comprehensive, easy-to-read account of their origins, classification and biology, and explains the features that distinguish them from other birds. The book devotes a major chapter to the 14 Australian species, covering their distribution and movements, feeding, breeding, population dynamics and conservation. Some of Australia’s herons have become very scarce in the southern half of the continent and are at risk of national or local extinction. In northern Australia heron habitats and resources are largely pristine and consequently this region accommodates large numbers of certain species. A final chapter on population and conservation provides a useful summary of the present status of the Australian herons, some of whom are thriving and others who are in a very precarious position.

Acacia sensu stricto is found predominantly in Australia; however, there are 18 phyllodinous taxa that occur naturally outside Australia, north from New Guinea to Indonesia, Taiwan, the Philippines, south-western Pacific (New Caledonia to Samoa), northern Pacific (Hawaii) and Indian Ocean (Mascarene Islands). Our aim was to determine the phylogenetic position of these species within Acacia, to infer their biogeographic history. To an existing molecular dataset of 109 taxa of Acacia, we added 51 new accessions sequenced for the ITS and ETS regions of nuclear rDNA, including samples from 15 extra-Australian taxa. Data were analysed using both maximum parsimony and Bayesian methods. The phylogenetic positions of the extra-Australian taxa sampled revealed four geographic connections. Connection A, i.e. northern Australia?South-east Asia?south-western Pacific, is shown by an early diverging clade in section Plurinerves, which relates A. confusa from Taiwan and the Philippines (possibly Fiji) to A. simplex from Fiji and Samoa. That clade is related to A. simsii from southern New Guinea and northern Australia and other northern Australian species. Two related clades in section Juliflorae show a repeated connection (B), i.e. northern Australia?southern New Guinea?south-western Pacific. One of these is the ?A. auriculiformis clade', which includes A. spirorbis subsp. spirorbis from New Caledonia and the Loyalty Islands as sister to the Queensland species A. auriculiformis; related taxa include A. mangium, A. leptocarpa and A. spirorbis subsp. solandri. The ?A. aulacocarpa clade' includes A. aulacocarpa, A. peregrinalis endemic to New Guinea, A. crassicarpa from New Guinea and Australia, and other Australian species. Acacia spirorbis (syn. A. solandri subsp. kajewskii) from Vanuatu (Melanesia) is related to these two clades but its exact position is equivocal. The third biogeographic connection (C) is Australia?Timor?Flores, represented independently by the widespread taxon A. oraria (section Plurinerves) found on Flores and Timor and in north-eastern Queensland, and the Wetar island endemic A. wetarensis (Juliflorae). The fourth biogeographic connection (D), i.e. Hawaii?Mascarene?eastern Australia, reveals an extreme disjunct distribution, consisting of the Hawaiian koa (A. koa, A. koaia and A. kaoaiensis), sister to the Mascarene (R�union Island) species A. heterophylla; this clade is sister to the eastern Australian A. melanoxylon and A. implexa (all section Plurinerves), and sequence divergence between taxa is very low. Historical range expansion of acacias is inferred to have occurred several times from an Australian?southern New Guinean source. Dispersal would have been possible as the Australian land mass approached South-east Asia, and during times when sea levels were low, from the Late Miocene or Early Pliocene. The close genetic relationship of species separated by vast distances, from the Indian Ocean to the Pacific, is best explained by dispersal by Austronesians, early Homo sapiens migrants from Asia.

Dr. Guy A. K. Marshall has recently submitted to me a Trypaneid, discovered in Northern Australia by Mr. G. F. Hill. The fly is said to have been bred from larvae having habits very different from those of the related members of the family; and being moreover interesting from a morphological and biogeographical standpoint, it forms the object of the present note.

Three new sites of <em>Orobanche arenaria</em> were discovered during floristic investigations in the Wyżyna Małopolska upland in central Poland. The new localities are concentrated in the Ponidzie area (Garb Pińczowski ridge and Niecka Połaniecka basin) and form the northern limit of the geographical range of <em>O. arenaria</em>. The paper presents information on the distribution of <em>Orobanche arenaria</em> in Poland, the abundance at the sites and habitats occupied by the species.
