Understanding the scale of marine population connectivity is critical for conservation and sustainable management resources. For many species adults are benthic relatively immobile, so patterns larval dispersal recruitment provide key to understanding connectivity. Contrary previous expectations, recent studies have often detected unexpectedly low fine-scale structure in sea, leading a paradigm shift how systems viewed. Nonetheless, link between underlying physical biological processes has...
Abstract Revealing the determinants of virome composition is central to placing disease emergence in a broader evolutionary context. Fish are most species-rich group vertebrates and so provide an ideal model system study factors that shape compositions their evolution. We characterized viromes nineteen wild-caught species marine fish using total RNA sequencing (meta-transcriptomics) combined with analyses sequence protein structural homology identify divergent viruses often evade...
Background Climate change will lead to intense selection on many organisms, particularly during susceptible early life stages. To date, most studies the likely biotic effects of climate have focused mean responses pooled groups animals. Consequently, extent which inter-individual variation mediates different has not been tested. Investigating this is important, since some individuals may be preadapted future scenarios. Methodology/Principal Findings We examined effect CO2-induced pH changes...
Signals in intraspecific communication should be inherently honest; otherwise the system is prone to collapse. Theory predicts, however, that honest signalling systems are susceptible invasion by cheats, extent of which largely mediated fear reprisal. Cuttlefish facultatively change their shape and colour, an ability evolved avoid predators capture prey. Here, we show this tactically employed male mourning cuttlefish ( Sepia plangon ) mislead conspecifics during courtship a specific social...
Aquaculture is the fastest growing industry worldwide. Aquatic diseases have had enormous economic and environmental impacts in recent past emergence of new aquatic pathogens, particularly viruses, poses a continuous threat. Nevertheless, little known about diversity, abundance evolution fish viruses. We used meta-transcriptomic approach to help determine virome seemingly healthy sold at market Sydney, Australia. Specifically, by identifying quantifying virus transcripts we aimed (i) viruses...
Determining the small-scale movement patterns of marine vertebrates usually requires invasive active acoustic tagging or in-water monitoring, with inherent behavioural impacts those techniques. In addition, these techniques rarely allow direct continuous assessments recording environmental interactions, especially for highly mobile species. Here, we trial a novel method assessing using an unmanned aerial vehicle that could complement longer-term tracking approaches. This approach is unlikely...
Citizen science can increase the scope of research in marine environment; however, it suffers from necessitating specialized training and simplified methodologies that reduce output. This paper presents a simplified, novel survey methodology for citizen scientists, which combines GoPro imagery structure motion to construct an ortho-corrected 3D model habitats analysis. Results using coral reef habitat were compared surveys conducted with traditional snorkelling methods benthic cover,...

The life-history strategies of some species make them strong candidates for rapid exploitation novel habitat under new climate regimes. Some early-responding may be considered invasive, and negatively impact on 'naïve' ecosystems. barrens-forming sea urchin Centrostephanus rodgersii is one such species, having a high dispersal capability high-latitude range margin limited only by developmental temperature threshold. Within this species' in eastern Australian waters, temperatures have...
Great hammerhead sharks Sphyrna mokarran are the largest member of Sphyrnidae, yet roles these large in food webs coastal ecosystems still poorly understood. Here we obtained samples muscle, liver and vertebrae from S. (234-383 cm total length; LT ) caught as by-catch off eastern Australia used stable-isotope analyses δ15 N, δ13 C δ34 S to infer their resource use any associated ontogenetic patterns. The results indicated apex predators primarily relying on other rays for diet, with a...
The way an animal behaves in its habitat provides insight into ecological role. As such, collecting robust, accurate datasets a time-efficient manner is ever-present pressure for the field of behavioural ecology. Faced with shortcomings and physical limitations traditional ground-based data collection techniques, particularly marine studies, drones offer low-cost efficient approach range coastal environments. Despite being widely used to monitor animals, they currently remain underutilised...
Abstract Biological invasions are among the biggest threats to freshwater biodiversity. This is increasingly relevant in Murray–Darling Basin, Australia, particularly since introduction of common carp (Cyprinus carpio). invasive species now occupies up ninety per cent fish biomass, with hugely detrimental impacts on native fauna and flora. To address ongoing carp, cyprinid herpesvirus 3 (CyHV-3) has been proposed as a potentially effective biological control agent. Crucially, however, it...
Abstract Background Childhood cancer survivors are vulnerable to long-term treatment-related health conditions, which can lead poor quality of life. Little data exist on the overall Australian and New Zealand childhood or survivors’ motivations for attending survivorship clinics. Methods This study administers a cross-sectional questionnaire ≥5 years from their primary diagnosis. We compared participant-reported number late effects by diagnosis, identified clinical (eg, treatment)...
Larvae of the Australian sea urchin Holopneustes purpurascens are induced to settle and metamorphose (termed settlement herein) by a water-soluble compound produced red alga Delisea pulchra, main host plant new recruits. The cue for H. had previously been identified as floridoside-isethionic acid complex, this paper presents evidence correcting that finding. actual D. pulchra was isolated from polar extract cation-exchange chromatography histamine, using one- two-dimensional nuclear magnetic...
