Diversity and sex differences in rectal gland volatiles of Queensland fruit fly, Bactrocera tryoni (Diptera: Tephritidae)
GC-FID profiles GC-FID analysis of rectal gland samples from flies of both sexes kept as virgin or in mixed sex groups showed up to 215 peaks with retention time (Rt) values from about 4.6 to 21 min. Only 184 of the peaks that were present in at least half the samples in at least one of the four sex/mating history categories were retained for further analysis (Table 2, Fig 1B, S1 Dataset, S2 and S3 Tables, S3 Fig).
Identifying corridors of river recovery in coastal NSW Australia, for use in river management decision support and prioritisation systems
How can corridor analysis be used to aid conservation and rehabilitation prioritisation and decision support systems? Prioritisation frameworks or protocols, employed in numerous management settings, apply predetermined criteria to rank projects in a consistent manner. In natural resource management, criteria can cover a broad spectrum of competing environmental, economic and social factors, and encompass both quantitative and qualitative factors [73, 74].

Cannabidiol but not cannabidiolic acid reduces behavioural sensitisation to methamphetamine in rats, at pharmacologically effective doses - Psychopharmacology
Abstract Rationale Cannabidiol (CBD) and cannabidiolic acid (CBDA) are non-psychoactive components of the cannabis plant. CBD has been well characterised to have anxiolytic and anticonvulsant activity, whereas the behavioural effects of CBDA are less clear. Preclinical and clinical data suggests that CBD has antipsychotic properties and reduces methamphetamine self-administration in rats.

Atmospheric dryness reduces photosynthesis along a large range of soil water deficits - Nature Communications
Abstract Both low soil water content (SWC) and high atmospheric dryness (vapor pressure deficit, VPD) can negatively affect terrestrial gross primary production (GPP). The sensitivity of GPP to soil versus atmospheric dryness is difficult to disentangle, however, because of their covariation. Using global eddy-covariance observations, here we show that a decrease in SWC is not universally associated with GPP reduction.
A large transposable element mediates metal resistance in the fungus Paecilomyces variotii
Highlights • A gene cluster in the fungus Paecilomyces variotii confers metal resistance • The gene cluster displays hallmarks of coordinated movement as a mobile element • The cluster is variably located in different genomic locations in different strains • HEPHAESTUS is an example of transposons carrying beneficial traits in eukaryotes Summary The horizontal transfer of large gene clusters by mobile elements is a key driver of prokaryotic adaptation in response to environmental stresses.
A constraint on historic growth in global photosynthesis due to increasing CO2 - Nature
Abstract The global terrestrial carbon sink is increasing1,2,3, offsetting roughly a third of anthropogenic CO2 released into the atmosphere each decade1, and thus serving to slow4 the growth of atmospheric CO2. It has been suggested that a CO2-induced long-term increase in global photosynthesis, a process known as CO2 fertilization, is responsible for a large proportion of the current terrestrial carbon sink4,5,6,7.
Trajectories of Self-Efficacy, Depressed Mood, and Anxiety From Admission to Spinal Cord Injury Rehabilitation to 1 Year After Discharge
Abstract Objective Self-efficacy (SE) is an important determinant for the psychological adjustment of people with spinal cord injury (SCI). However, little is known about the course of SE during inpatient rehabilitation up to 1 year after discharge. The aim of this study was to determine latent trajectory classes of SE, depressive mood, and anxiety in people with SCI, as well as the interrelationships between these trajectories.

Mistaken identity may explain why male sea snakes (Aipysurus laevis, Elapidae, Hydrophiinae) “attack” scuba divers - Scientific Reports
Abstract Scuba-divers on tropical coral-reefs often report unprovoked “attacks” by highly venomous Olive sea snakes (Aipysurus laevis). Snakes swim directly towards divers, sometimes wrapping coils around the diver’s limbs and biting. Based on a focal animal observation study of free-ranging Olive sea snakes in the southern Great Barrier Reef, we suggest that these “attacks” are misdirected courtship responses.

Effects of very low-carbohydrate vs. high-carbohydrate weight loss diets on psychological health in adults with obesity and type 2 diabetes: a 2-year randomized controlled trial - European Journal of Nutrition
Abstract Aims Very low-carbohydrate (LC) diets are popular for type 2 diabetes (T2DM) management; however, long-term effects on psychological health remain largely unknown. This study reports the effects of a LC diet on mood and cognitive function after 2 years and explores the potential predictors of changes in psychological health.
Tectonic cycles of the New England Orogen, eastern Australia: A Review
Abstract The New England Orogen (NEO), the youngest of the orogens of the Tasmanides of eastern Australia, is defined by two main cycles of compression–extension. The compression component involves thrust tectonics and advance of the arc towards the continental plate, while extension is characterised by rifting, basin formation, thermal relaxation and retreat of the arc towards the oceanic plate.
Mating behaviour of the marine turbellarian Macrostomum sp.: these worms suck

Kimberlite genesis from a common carbonate-rich primary melt modified by lithospheric mantle assimilation
Abstract Quantifying the compositional evolution of mantle-derived melts from source to surface is fundamental for constraining the nature of primary melts and deep Earth composition. Despite abundant evidence for interaction between carbonate-rich melts, including diamondiferous kimberlites, and mantle wall rocks en route to surface, the effects of this interaction on melt compositions are poorly constrained.

Honey bees solve a multi-comparison ranking task by probability matching
Abstract Honey bees forage on a range of flowers, all of which can vary unpredictably in the amount and type of rewards they offer. In this environment bees are challenged with maximising the resources they gather for their colony. That bees are effective foragers is clear, but how bees solve this type of complex multi-choice task is unknown. Here we challenged bees with a five-comparison choice task in which five colours differed in their probability of offering reward and punishment.
Bumble bees display cross-modal object recognition between visual and tactile senses
These bees have “seen” that before Humans excel at mental imagery, and we can transfer those images across senses. For example, an object out of view, but for which we have a mental image, can still be recognized by touch. Such cross-modal recognition is highly adaptive and has been recently identified in other mammals, but whether it is widespread has been debated. Solvi et al.

The Extended Genotype: Microbially Mediated Olfactory Communication
Highlights We have recently moved from viewing species, individuals, and their DNA as fundamental units of biological organization, to recognizing that the microbiome contributes to the macroorganism’s genome and hence its phenotype; this collective of organisms is termed the holobiont. There are complex bidirectional interactions, mediated by chemical signals, between hosts and their microbiota.

Reproductive strategy and gamete development of an invasive fanworm, Sabella spallanzanii (Polychaeta: Sabellidae), a field study in Gulf St Vincent, South Australia
Several reproductive strategies have been identified as key factors that contribute to the establishment and dispersal of invasive species in new environments. These strategies include early maturity, high reproductive capacity and flexibility in timing of reproduction. It is therefore critical to investigate the reproductive biology of target exotic species to understand their potential for population increase and invasive spread, and to inform management control strategies.
Combining dispersal, landscape connectivity and habitat suitability to assess climate-induced changes in the distribution of Cunningham’s skink, Egernia cunninghami
The ability of species to track their climate niche is dependent on their dispersal potential and the connectivity of the landscape matrix linking current and future suitable habitat. However, studies modeling climate-driven range shifts rarely address the movement of species across landscapes realistically, often assuming “unlimited” or “no” dispersal.
Gene expression allelic imbalance in ovine brown adipose tissue impacts energy homeostasis
Heritable trait variation within a population of organisms is largely governed by DNA variations that impact gene transcription and protein function. Identifying genetic variants that affect complex functional traits is a primary aim of population genetics studies, especially in the context of human disease and agricultural production traits.
Within-season variability of fighting behaviour in an Australian alpine grasshopper
Throughout the breeding season, changing environmental and biological conditions can lead to variation in the reproductive landscape of many species. In alpine environments temperature is a key driver of behaviour for small ectotherms such as insects, but variable biotic factors such as mate quality and availability can also influence behaviour. Kosicuscola tristis is a small semelparous grasshopper of the Australian alpine region. In a rare behaviour among grasshoppers, K.
Comment on “Mycorrhizal association as a primary control of the CO2 fertilization effect”
AbstractTerrer et al. (Reports, 1 July 2016, p. 72) used meta-analysis of carbon dioxide (CO2) enrichment experiments as evidence of an interaction between mycorrhizal symbiosis and soil nitrogen availability. We challenge their database and biomass as the response metric and, hence, their recommendation that incorporation of mycorrhizae in models will improve predictions of terrestrial ecosystem responses to increasing atmospheric CO2.

An Analysis of Citizen Science Based Research: Usage and Publication Patterns
The use of citizen science for scientific discovery relies on the acceptance of this method by the scientific community. Using the Web of Science and Scopus as the source of peer reviewed articles, an analysis of all published articles on “citizen science” confirmed its growth, and found that significant research on methodology and validation techniques preceded the rapid rise of the publications on research outcomes based on citizen science methods.
Mechanisms of Color Production in a Highly Variable Shield-Back Stinkbug, Tectocoris diopthalmus (Heteroptera: Scutelleridae), and Why It Matters
Theory suggests that aposematism, specifically the learned avoidance of unprofitable prey via memorable color patterns, should result in selection for pattern uniformity. However, many examples to the contrary are seen in nature. Conversely, honest sexual signals are likely to exhibit greater variation because they reflect underlying variation in mate quality.
Enhanced Australian carbon sink despite increased wildfire during the 21st century
Climate projections show Australia becoming significantly warmer during the 21st century, and precipitation decreasing over much of the continent. Such changes are conventionally considered to increase wildfire risk. Nevertheless, we show that burnt area increases in southern Australia, but decreases in northern Australia. Overall the projected increase in fire is small (0.72–1.31% of land area, depending on the climate scenario used), and does not cause a decrease in carbon storage.
