Abstract (sommario):
A hybrid origin for a conservation listed taxon will influence its status and management options. Here, we investigate the genetic origins of a nationally endangered listed taxon—Eucalyptus paludicola—a tree that is restricted to the Fleurieu Peninsula and Kangaroo Island of South Australia. Since its description in 1995, there have been suggestions that this taxon may potentially be a stable hybrid species. Using a high throughput sequencing approach, we developed a panel of polymorphic loci that were screened across E. paludicola and its putative parental species E. cosmophylla and E. ovata. Bayesian clustering of the genotype data identified separate groups comprising E. ovata and E. cosmophylla while E. paludicola individuals were admixed between these two, consistent with a hybrid origin. Hybrid class assignment tests indicate that the majority of E. paludicola individuals (~70%) are F1 hybrids with a low incidence of backcrossing. Most of the post-F1 hybrids were associated with revegetation sites suggesting they may be maladapted and rarely reach maturity under natural conditions. These data support the hypothesis that E. paludicola is a transient hybrid entity rather than a distinct hybrid species. We briefly discuss the conservation implications of our findings.

Abstract (sommario):
Identification of Australian species of Nitella is problematic. Several species of monoecious Nitella have been described from south-eastern mainland Australia, but identification of these based on current treatments has been difficult. In response to the discovery of a new monoecious Nitella from the swamps of the Fleurieu Peninsula in South Australia, the monoecious species of Nitella from south-eastern mainland Australia were examined and compared. N. paludigena M.T.Casanova & K.G.Karol is distinguished from other monoecious species on the basis of its overall vegetative morphology and oospore morphology. N. paludigena is found in peaty tea-tree (Leptospermum sp) swamps on the Fleurieu Peninsula in South Australia, and in the south-west of Victoria. A description of the morphology and ecology of the five monoecious Nitella species from south-eastern mainland Australia is given, along with a key.

Abstract (sommario):
Morphological variation in Eucalyptus baxteri (Benth.) Maiden & Blakely ex Black is described throughout its range. There are two geographical forms, the principal differences between which are seedling morphology and the time of transition from juvenile to intermediate growth phase. The forms are hereby recognised as two species. E. baxteri s.str. has adult leaves broad near the apex, warty flower buds, often large fruits, and an early transition to intermediate foliage. It occurs in South Australia on Kangaroo Island, Fleurieu Peninsula, Barossa Range and near Wandilo, and in Victoria on the Grampian Ranges, Great Dividing Range and coastal areas, E. arenacea sp. nov. has tapering adult leaves, generally more slender, non-warty flower buds with longer, narrower pedicels and peduncles. Fruits are generally smaller with the disc less raised. Seedlings typically show a later transition to the intermediate foliage. It occurs on Mt Stapylton in the Grampian Ranges and the desert sand country of north-western Victoria and south-eastern South Australia. It is parapatric with E. baxteri on Kangaroo Island and Fleurieu Peninsula, and is restricted to sand deposits. A previous cladistic analysis suggested that E. baxteri s.l. is paraphyletic, E. arenacea sp. nov. being the sister taxon to E. baxteri s.str. and E. akina (an endemic of the Grampian Ranges). A sequence of evolutionary events is hypothesised by using the cladogram, the distribution of the taxa on different soils, and the geological history of the region.

Abstract (sommario):
This study examined parasites occurring in the insular subspecies of the western grey kangaroo, Macropus fuliginosus fuliginosus, from Kangaroo Island. A total of 25 kangaroos from three sites were examined for gastrointestinal parasites. Fifteen parasite species were identified: eight in the stomach, five in the small intestine and two in the large intestine. Parasite prevalence showed a bimodal distribution: 'satellite' species were predominantly cestodes, whereas 'core' species were nematodes. There was no evidence of co-speciation in the 12 parasite species occurring in both island and mainland western grey kangaroo subspecies. M. f. fuliginosus harboured fewer parasite species than M. f. melanops from the Fleurieu Peninsula, South Australia. This might be related to parasite prevalence and the intensity of infection in the original population of kangaroos. Alternatively, it might be related to differing environmental conditions or to chance. Host switching was evident, with Cloacina kartana, which has been recorded as a common parasite of the tammar wallaby, Macropus eugenii, also occurring in some kangaroos.

Abstract (sommario):
Over the last 200 years Australia has suffered the greatest rate of mammal species extinction of any continent. This demands extensive biodiversity research, but unfortunately has been hampered by poor documentation of Australia’s native species at the time of European colonization. Late-Holocene fossil mammal assemblages preserved in caves, rockshelters and surface lag deposits from deflated sand dunes can provide a more complete understanding of pre-European ecological conditions than can be developed from our knowledge of present biodiversity. In South Australia, few regions have experienced greater landscape modification and biodiversity loss than Yorke Peninsula. We investigate the composition, richness, evenness and age of two owl accumulations from southeastern and southwestern Yorke Peninsula and contrast them with a surface lag deposit assemblage probably accumulated by humans. We then examine the pre-European biogeography of the fauna recovered. The three assemblages have similar species richness, but differ dramatically in composition and evenness. The biases imposed by differing accumulation agents can explain compositional differences between owl and human assemblages, but not the differences between the respective owl accumulations. We argue that key substrate differences – one area is dominated by sand and the other by calcrete – have favoured distinct vegetation communities that fostered distinctly different mammal assemblages from which raptors accumulated prey. The ecological requirements of the extant mammals appear to be reflected in the fossil assemblages, providing support for the application of uniformitarian principles and confidence in the relevance of late-Holocene fossil assemblages to modern conservation and natural resource management.
