The post-embryonic ontogeny of the early Cambrian trilobite Estaingia bilobata from South Australia: trunk development and phylogenetic implications
<p>Trilobites are one of the most diverse and abundant fossil groups from the early Palaeozoic, and as such are useful for answering important questions about early animal evolution, including developmental processes. Ontogenetic information for a large number of trilobite species has been published, but cases where multiple articulated specimens are known across the full range of developmental stages are rare. The early Cambrian (Series 2, Stage 4) Emu Bay Shale biota from Kangaroo Island (South Australia) is numerically dominated by trilobites, particularly articulated specimens of the ellipsocephaloid <i>Estaingia bilobata</i>, which are present in densities of >600 individuals per square metre on certain bedding planes. Here we describe the essentially complete post-embryonic ontogenetic series of <i>E. bilobata</i> from the Emu Bay Shale, and investigate patterns of growth relating to articulation and segmentation in this early Cambrian arthropod. <i>Estaingia bilobata</i> exhibits the hypoprotomeric mode of growth, with the epimorphic phase (the cessation of trunk segment generation) reached prior to the onset of the holaspid period. The meraspid pygidium had an extended equilibrium period where anterior segment release into the thorax was matched by sub-terminal segment generation. Previously undocumented morphological features of <i>E. bilobata</i>, including the hypostome and bispinose pleural tips in holaspides, are also described. The growth characteristics and morphological features of <i>E. bilobata </i>documented herein strengthen close phylogenetic relationships between the Estaingiidae, Ellipsocephalidae and Xystriduridae.</p>

Data from: An assessment of ancient DNA preservation in Holocene-Pleistocene fossil bone excavated from the world heritage Naracoorte Caves, South Australia
Although there is a long history of research into the fossil deposits of the Naracoorte Caves (South Australia), ancient DNA (aDNA) has not been integrated into any palaeontological study from this World Heritage site. Here, we provide the first evidence of aDNA preservation in Holocene- and Pleistocene-aged fossil bone from a deposit inside Robertson Cave. Using a combination of metabarcoding and shotgun next-generation sequencing approaches, we demonstrate that aDNA from diverse taxa can be retrieved from bulk bone as old as 18 600 cal a BP. However, the DNA is highly degraded and contains a lower relative proportion of endogenous sequences in bone older than 8400 cal a BP. Furthermore, modelling of DNA degradation suggests that the decay rate is rapid, and predicts a very low probability of obtaining informative aDNA sequences from extinct megafaunal bones from Naracoorte (ca. 50 000 cal a BP). We also provide new information regarding the past faunal biodiversity of Robertson Cave, including families that have not been formerly described in the fossil record from here before. Collectively, these data demonstrate the potential for future aDNA studies to be conducted on material from Naracoorte, which will aid in the understanding of faunal turnover in southern Australia.
Data from: Comparative analysis indicates historical persistence and contrasting contemporary structure in sympatric woody perennials of semi-arid south-west Western Australia
We used a comparative approach to assess congruence of phylogeographic and genetic structure and diversity, demographic signals, and ratios of pollen to seed dispersal, in the context of species-specific life-history traits, for two widespread sympatric perennial plant species. We sampled Grevillea paradoxa and Melaleuca nematophylla across the species' ranges throughout the Transitional Rainfall Zone and extending slightly into the Arid Zone of south-west Western Australia. Both species exhibited range-wide phylogeographic and contemporary genetic structure. Moderate haplotype diversity centred in populations on Banded Ironstone Formation (BIF) outcrops and within the Murchison River gorge supports a hypothesis of historical persistence and evolution in these mesic refugia. These features are likely to play important roles in evolutionary persistence with ongoing climate change. There was little evidence of particularly complex demographic histories for the region. More limited haplotype diversity, as well as more limited nuclear genetic diversity and connectivity, in G. paradoxa was consistent with predictions from life-history traits of shorter lifespan, lower fecundity, more limited seed dispersal, and shorter plants, but inconsistent with a prediction of greater pollen dispersal by bird pollinators. Low pollen to seed dispersal ratios suggest seed dispersal plays a greater than expected role in maintaining connectivity in this semi-arid landscape. The study highlights a need for research that integrates aspects of seed ecology and seed and pollen dispersal as well as phylogeographic and genetic patterns in Gondwanan shrublands and other semi-arid landscapes globally.
Data from: An early Cambrian chelicerate from the Emu Bay Shale, South Australia
The Emu Bay Shale Lagerstätte (Cambrian Series 2, Stage 4) occurs on the north coast of Kangaroo Island, South Australia. Over 50 species are known from here, including trilobites and non-biomineralized arthropods, palaeoscolecids, a lobopodian, a polychaete, vetulicolians, nectocaridids, hyoliths, brachiopods, sponges and chancelloriids. A new chelicerate, Wisangocaris barbarahardyae gen. et sp. nov., is described herein, based on a collection of some 270 specimens. It is up to 60 mm long, with the length of the cephalic shield comprising about 30% that of the exoskeleton. The cephalic margin has three pairs of bilaterally-symmetrical small triangular spines. A pair of small eyes is placed well forwards on the ventral margin of the cephalic shield. The trunk comprises 11 segments that increase in length while narrowing posteriorly, each possibly bearing a pair of biramous appendages; the most posterior segment is almost square whereas the others are transversely elongated. The spatulate telson is proportionately longer than in taxa such as Sanctacaris, Utahcaris and Leanchoilia. Up to eight (?four pairs) of 3 mm-long elements bearing alternating inward-curving short and long spines beneath the cephalic shield are interpreted as basipodal gnathobases, part of a complex feeding apparatus. A well-developed gut includes a stomach within the cephalic shield; it extends to the base of the telson. In a few specimens there are shell fragments within the gut, including those of the trilobite Estaingia bilobata (the most common species in the biota); these fragments have sharp margins and extend across the gut lumen. The species may have been a predator or a scavenger, ingesting material already broken up by a larger predator/scavenger. The morphology of this taxon shares many overall body features with Sanctacaris, and some with Sidneyia, particularly its gnathobasic complex. These chelicerate affinities are corroborated by phylogenetic analyses.
Data from: Persistence with episodic range expansion from the early Pleistocene: the distribution of genetic variation in the forest tree Corymbia calophylla (Myrtaceae) in south-western Australia
Phylogeographic patterns of trees in topographically subdued, unglaciated landscapes are under-reported, and might reflect population persistence and the influences of environment and distance over historical (~2.6Mya-present) and contemporary (recent generations) time-scales. We examined this hypothesis using genetic analyses of four slowly evolving non-coding chloroplast sequences and 16 nuclear microsatellites in the tree Corymbia calophylla from south-western Australia that has been unglaciated since the Permian (.300-250Mya). We found strong population differentiation for chloroplast DNA and low differentiation for nuclear loci, consistent with higher gene flow by pollen than seed. We identified three divergent chloroplast lineages distributed in central, north and south geographic regions, and diversifying from the early (.3.028Mya), mid- (.0.793Mya) and late- (.0.426Mya) Pleistocene, respectively. Moderate-high nucleotide diversity with population-specific haplotypes supported long-term persistence but diversification of lineages provided evidence of unexpected episodic range expansion. We suggest this pattern reflects environmental influences of climatic oscillations during progressive drying of south-western Australia from the early Pleistocene. Significant tests for isolation by environment for nuclear loci also supported an influence of contemporary environmental (aridity) conditions on genetic structure, but isolation by distance (IBD) was greater. Significant chloroplast and nuclear IBD suggested distance was a major influence on gene flow at both time-scales.
Data from: Hydrological conditions explain wood density in riparian plants of south-eastern Australia
1. Wood density is a key plant functional trait which integrates the trade-offs characteristic to riparian plant ecological strategies. Although high-density wood is costly to construct, it confers mechanical stiffness to stems, increasing a plant's capacity to withstand flooding, and also enables increased tolerance to water stress. For riparian plants, fluctuations in soil moisture driven by surface hydrology should therefore be an important driver of variation in wood density. 2. We asked the following questions in the study: (1) Does wood density increase with increasing frequency and magnitude of flood disturbance? (2) Does wood density increase with increasing unpredictability of water availability in the riparian zone? (3) Does dispersion of wood density peak at intermediate levels of hydrological disturbance? 3. We surveyed wood density of dominant species at 15 riparian sites along flow-gauged rivers across south-eastern Australia. Due to the broad range of hydrological variability associated with Australian river systems, this set of sites functions as a useful model for assessing the response of riparian plants to changing hydrological conditions. 4. We found wood density varied strongly along a single axis of hydrological variability. This axis integrates flood intensity and frequency with metrics of hydrological unpredictability and can be conceptualized as a gradient of environmental harshness, with higher wood density associated with harsher conditions. 5. Synthesis. Our study highlights the importance of hydrological conditions, particularly disturbance and environmental unpredictability, as determinants of ecological strategy in riparian plants. Large, rare flood events in particular appear to favour higher wood density strategies. This is likely to have significant ecological consequences for riparian plant communities in a south-east Australian context, as well as in other regions where increasing climatic variability and frequency of extreme events are hallmarks of climate change predictions.
