Abstract (sommario):

Wollemia nobilis (Wollemi pine), an araucariaceous plant, whose closest known relatives are from the Jurassic period, occurs in the Wollemi National Park near Sydney, Australia. This tree is host to many endophytic fungi, including Pestalotiopsis guepinii which produces taxol, an important anticancer drug. It was shown by immunological, spectroscopic and chromatographic means to be identical with authentic taxol obtained from Taxus brevifolia (Pacific yew). Since the Wollemi pine does not produce taxol, how might a taxol-producing fungus be present in this unusual tree? Spores of P. guepinii possess several appendages which strongly interact with hydrophobic surfaces including plastics and the pinnae of birds’ feathers. Scanning electron microscopy of the conidia of P. guepinii clearly shows the spores on the feathers of a green-checked conure and a cockatiel. Conceivably, the fungus may have acquired the ability to produce taxol from a foreign or local yew and then is carried to the Wollemi pine site by native birds.

Abstract (sommario):

The critically endangered Wollemia nobilis W.G. Jones, K.D. Hill & J.M. Allen is endemic to Wollemi National Park north of Sydney (Australia). All known wild individuals are restricted to four sites in a single canyon system. W. nobilis can reproduce sexually but at all sites individual clumps can be multi-stemmed from a common base. In the first genetic study of this species, no genetic variation was found across multiple genetic marker types representing hundreds of nuclear loci, indicating this species is characterised by very low genetic variation. In this study we searched for variation across the chloroplast using shotgun sequencing, bioinformatic extraction of chloroplast DNA and variant detection. Six chloroplast single nucleotide polymorphisms were detected, producing three chlorotypes. Chlorotype 1 is found in every individual surveyed at Sites 1 and 3, and in individuals from Sites 2 and 4. Chlorotype 2 – the most distinct chlorotype – was found in two individuals from Site 4. Chlorotype 3 consists of a single difference from Chlorotype 1 and may represent a somaclonal mutant. These findings will guide management and translocation of this critically endangered species. This study provides a practical template that is highly informative and easily applicable to other taxa in similar circumstances.

Abstract (sommario):

Whether the eastern quoll (Dasyurus viverrinus) is extinct on mainland Australia, particularly New South Wales (NSW), is the focus of this study. The species declined rapidly during the mid to late 1800s in parts of south-east Australia and in the early 1900s around Bega (New South Wales). The last definite live individual was recorded at Vaucluse, NSW in 1963. The recent emergence of a specimen from Barrington Tops, NSW, in 1989 caused much public interest and enabled us to seek reports of sightings after we advertised publicly for any records. Here we document numerous post-1963 records, the most noteworthy including: a photograph of an eastern quoll (reported to be taken in 2013 in the Nungatta area of NSW), records from Wollemi National Park (2002 and 2006) and multiple observations from the 1990s from around Barrington Tops and Carrai. There has been insufficient recent mammal survey effort to definitively support these public reports but at this stage there are sufficient recent credible records to consider that this species may not be extinct on mainland Australia.

Abstract (sommario):

The south-eastern Australian helicarionid clade currently comprises six genera of snails and semislugs united by genital characters, including an epiphallic flagellum that produces a spiraling, spinose spermatophore, the absence of an epiphallic caecum, and the presence of at most a very short vagina. We comprehensively revise the taxonomy of this group based on comparative analyses of key morphological features and mitochondrial markers COI and 16S, revise the placement of several species described recently on the basis of shell morphology alone, and describe new taxa. The snail genus Brevisentis is monophyletic as currently understood, but includes an additional undescribed species from Wollemi National Park, New South Wales. Mysticarion is shown to contain four arboreal semislugs with wide, disjunct ranges, including one new species (Mysticarion obscurior sp. nov.). We synonymise Fastosarion staffordorum with Mysticarion hyalinus. The semislug Desidarion is synonymised with Parmavitrina, and we describe two new species of this genus, P. flavocarinata sp. nov. and P. maculosa sp. nov. The semi-arboreal semislug Cucullarion is herein included in the south-eastern Australian helicarionid clade based on morphological and genetic evidence, despite its more northerly distribution. Two small semislugs so far placed in Peloparion do not group together and a new genus, Ubiquitarion gen. nov., is described for Peloparion iridis. All of these genera, together with the semislug Helicarion (not included here), form a monophyletic radiation endemic to southeastern Australia.

Abstract (sommario):

This study covers the following aspects of mine water management at the Clarence Colliery, located at the headwaters of the Wollangambe River, N.S.W. The Wollangambe River flows through the World Heritage listed areas of the Blue Mountains and Wollemi National Parks. 1. Quantification of the impact of discharge of treated mine water on the Wollangambe River, through analysis of sediment metal concentrations. 2. Investigation of the possible sources and causes of acid mine drainage within the mine. 3. Review of the current treatment process employed at the mine, as well as a review of other possible treatment options for avoidance or treatment of acid mine drainage. 4. Recommendation of a strategy for improving the process of mine water management at the colliery. The study reveals problems discovered from the investigation and describes the findings and recommendations.
