Utterances

Ainslie Murray
Utterances considers the role of the body in generating architectural space by actively incorporating the shadows cast by a wandering audience into the work. The currency of physical entities is called into question as shadows of the body appear to move amongst the panels even as the body itself remains distant. The creative tension between the tangible and the intangible becomes evident in the space between the perforated works and their shadows; an ambiguous architectural...

Impact of Southern Ocean convection on the climate and carbon cycle

Laurie Menviel

Conspicuous animal signals avoid the cost of predation by being intermittent or novel: confirmation in the wild using hundreds of robotic prey

Terry Ord
Social animals are expected to face a trade-off between producing a signal that is detectible by mates and rivals, but not obvious to predators. This trade-off is fundamental for understanding the design of many animal sig- nals, and is often the lens through which the evolution of alternative communication strategies is viewed. We have a reasonable working knowl- edge of how conspecifics detect signals under different conditions, but how predators exploit conspicuous communication of prey...

Lessons from a century of conservation translocations

Shane D Morris, Barry W Brook, Katherine E Moseby & Christopher N Johnson
Translocation—moving individuals for release in new locations—is among the most important conservation interventions for increasing or re-establishing populations of threatened species. However, translocations often fail. To improve their effectiveness, we need to understand the features that distinguish successful from failed translocations. Here, we assembled and analysed a global database of translocations of terrestrial vertebrates (n=514) to assess the effects of various design features and extrinsic factors on success. Unlike previous reviews, we analysed outcomes using...

Data from: Spatial phylogenetics of the North American flora

Brent Mishler, Robert Guralnick, Pamela Soltis, Stephen Smith, Douglas Soltis, Narayani Barve, Julie Allen & Shawn Laffan
North America is a large continent with extensive climatic, geological, soil, and biological diversity. That biota is under threat from habitat destruction and climate change, making a quantitative assessment of biodiversity of critical importance. Rapid digitization of plant specimen records and accumulation of DNA sequence data enable a much-needed broad synthesis of species occurrences with phylogenetic data. Here we attempted the first such synthesis of a flora from such a large and diverse part of...

Climate change, sex reversal, and lability of sex determining systems

Lisa Schwanz, Arthur Georges, Clare Holleley & Stephen Sarre
Sex reversal at high temperatures during embryonic development (e.g. ZZ females) provides the opportunity for new genotypic crosses (e.g. ZZ male x ZZ female). This raises the alarming possibility that climatic warming could lead to the loss of an entire chromosome – one member of the sex chromosome pair (the Y or W) – and the transition of populations to environmental sex determination (ESD). Here we examine the evolutionary dynamics of sex-determining systems exposed to...

Data from: The sex with the reduced sex chromosome dies earlier: a comparison across the tree of life

Zoe A. Xirocostas, Susan E. Everingham & Angela T. Moles
Many taxa show substantial differences in lifespan between the sexes. However, these differences are not always in the same direction. In mammals, females tend to live longer than males, while in birds, males tend to live longer than females. One possible explanation for these differences in lifespan is the unguarded X hypothesis, which suggests that the reduced or absent chromosome in the heterogametic sex (e.g. the Y chromosome in mammals and the W chromosome in...

Data from: Evolution of defence and herbivory in introduced plants - testing enemy release using a known source population, herbivore trials and time since introduction

Claire Brandenburger, Martin Kim, Eve Slavich, Floret Meredith, Juha-Pekka Salminen, William Sherwin & Angela Moles
The enemy release hypothesis is often cited as a potential explanation for the success of introduced plants; yet empirical evidence for enemy release is mixed. We aimed to quantify changes in herbivory and defence in introduced plants while controlling for three factors that might have confounded past studies: using a wide native range for comparison with the introduced range, measuring defence traits without determining whether they affect herbivore preferences, and not considering the effect of...

Supplemental data: The association of dilated perivascular spaces with cognitive decline and incident dementia

Matthew Paradise, John Crawford, Ben Lam, Wei Wen, Nicole Kochan, Steve Makkar, Laughlin Dawes, Julian Trollor, Brian Draper, Henry Brodaty & Perminder Sachdev
Objective: To determine if severe perivascular space (PVS) dilation is associated with longitudinal cognitive decline and incident dementia over four and eight years respectively, we analyzed data from a prospective cohort study. Methods: 414 community dwelling older adults aged 72-92 were assessed at baseline and biennially for up to eight years, with cognitive assessments, consensus dementia diagnoses and 3T MRI imaging. The numbers of PVS in two representative slices in the basal ganglia (BG) and...

Signatures of selection in a recent invasion reveals adaptive divergence in a highly vagile invasive species

Katarina Stuart, Adam Cardilini, Phillip Cassey, Mark Richardson, William Sherwin, Lee Rollins & Craig Sherman
A detailed understanding of population genetics in invasive populations helps us to identify drivers of successful alien introductions. Here, we investigate putative signals of selection in Australian populations of invasive common starlings, Sturnus vulgaris, and seek to understand how these have been influenced by introduction history. We used reduced representation sequencing to determine population structure, and identify Single Nucleotide Polymorphisms (SNPs) that are putatively under selection. We found that since their introduction into Australia, starling...

Seed traits determine species responses to fire under varying soil heating scenarios

Ryan Tangney
1) Many plant species in fire-prone environments maintain persistence through fire via soil seedbanks. However, seeds stored within the soil are at risk of mortality from elevated soil temperatures during fire. Seeds may be protected from fire-temperature impacts by burial, however those buried too deeply may germinate but fail to emerge. Thus, successful post-fire seed regeneration is contingent upon a trade-off between burial depth and survival through fire. 2) We examined the relationships between seedling...

Data used in "Enhanced mid-depth southward transport in the Northeast Atlantic at the Last Glacial Maximum"

A high-resolution reanalysis of the East Australian Current System assimilating an unprecedented observational data set using 4D-Var data assimilation over a two-year period (2012-2013). Version 2017.

Colette Kerry, Moninya Roughan, Brian Powell & Peter Oke
For the EAC region, we combine a high-resolution state-of-the-art numerical ocean model with a variety of traditional and newly available observations using an advanced variational data assimilation scheme. The numerical model is configured using the Regional Ocean Modelling System (ROMS 3.4) and takes boundary forcing from the BlueLink ReANalysis (BRAN3). For the data assimilation, we use an Incremental Strong- Constraint 4-Dimensional Variational (IS4D-Var) scheme, which uses the model dynamics to perturb the initial conditions, atmospheric...

Environmental cues for dispersal in a filamentous fungus in simulated islands

Justin Chan, Stephen Bonser, Jeff Powell & William Cornwell
Airborne dispersal is a key part of the life history of many saprotrophic fungi. Theory suggests a transition from growth and resource capture to airborne dispersal at some point as the resource availability in a patch declines, but in the absence of an experimental model system this theory has not been empirically tested. For saprobes, resources are arrayed in an ever-shifting archipelago of islands with the quality of each island being defined by patch size...

Data from: Animal models to understand the etiology and pathophysiology in polycystic ovary syndrome

Elisabet Stener-Victorin, Vasantha Padmanabhan, Kirsty A Walters, Rebecca E Campbell, Anna Benrick, Paolo Giacobini, Daniel A Dumesic & David H Abbott
More than one out of ten women worldwide are diagnosed with the leading cause of female reproductive and metabolic dysfunction, polycystic ovary syndrome (PCOS). Despite its high prevalence, PCOS and its accompanying morbidities are likely under-diagnosed, averaging >2 years and 3 physicians changes before women are diagnosed. Despite intensive research, the underlying cause(s) of PCOS have yet to be defined. In order to understand PCOS pathophysiology, its developmental origins, and how to predict and prevent...
