A rapid perceptual test of the other-race effect

Daniel Guilbert
This study explores the other-race effect in face recognition, using a paradigm in which two faces are presented very rapidly one after another, and participants decide whether they belong to the same person or two different people.

Mimicry in motion and morphology: do information limitation, trade-offs or compensation relax selection for mimetic accuracy?

Donald McLean & Marie Herberstein
Many animals mimic dangerous or undesirable prey as a defence from predators. We would expect predators to reliably and exclusively avoid animals that closely resemble dangerous prey, yet imperfect mimics are common. There have been many hypotheses suggested to explain imperfect mimicry, but comparative tests across multiple mimicry systems are needed to determine which are applicable, and which—if any—represent general principles of imperfect mimicry. We tested four hypotheses on Australian ant mimics and found support...

Selection for male weapons boosts female fecundity, eliminating sexual conflict in the bulb mite

Bruno Buzatto & Huon Clark
Extreme differences between the sexes are usually explained by intense sexual selection on male weapons or ornaments. Sexually antagonistic genes, with a positive effect on male traits but a negative effect on female fitness, create a negative inter-sexual correlation for fitness (sexual conflict). However, such antagonism might not be apparent if sexually selected male traits are condition-dependent, and condition elevates female fitness. Here we reveal a surprising positive genetic correlation between male weaponry and female...

Larval and metamorph traits of cane toads

Richard Shine, Uditha Wijethunga, Matthew Greenlees & Melanie Elphick
As an invasive organism spreads into a novel environment, it may encounter strong selective pressures to adapt to abiotic challenges. We examined the effect of water temperature during larval life on rates of survival and growth of the early life-history stages of cane toads (Rhinella marina) from two geographic regions (tropical vs. temperate) in the species’ invaded range in eastern Australia. If local adaptation at the southern (cool-climate) invasion front has extended the cold-tolerance of...

Fossil evidence unveils an early Cambrian origin for Bryozoa

Zhiliang Zhang, Zhifei Zhang, Junye Ma, Paul Taylor, Luke Strotz, Sarah Jacquet, Christian Skovsted, Feiyang Chen, Jian Han & Glenn Brock
Bryozoans (ectoprocts or moss animals) are aquatic, dominantly sessile, filter-feeding lophophorates that construct an organic or calcareous modular colonial (clonal) exoskeleton. The presence of six major orders of bryozoans with advanced polymorphisms in lower Ordovician rocks strongly suggests a Cambrian origin for the largest and most diverse lophophorate phylum. However, a lack of convincing bryozoan fossils from the Cambrian has hampered resolution of the true origins and character assembly of earliest members of the group....

Silencing circular RNA circ_0054537 and upregulating microRNA-640 suppress malignant progression of renal cell carcinoma via regulating neuronal pentraxin-2 (NPTX2)

Long Pei, Xianqiang Lv, Gaopei Jia, Xiaoliang Tan, Ming Li & Aili Zhang
Hsa_circ_0054537 (circ_0054537) is a novel tumor-related circular RNA in renal cell carcinoma (RCC), and we intended to ascertain its dysregulation and functions in RCC malignant progression, as well as the underlying mechanism via serving as competing endogenous RNA (ceRNA). In this research, using real-time quantitative PCR, we found circ_0054537 was upregulated in RCC tissues and cells, and distributed throughout the cytoplasm. Then, functional effects of circ_0054537 in RCC were detected using cell counting kit-8, transwell,...

Genomic and transcriptomic data for the frog Platyplectrum ornatum

Scott Edwards, Sangeet Lamichhaney, Renee Catullo, Scott Keogh, Simon Clulow & Tariq Ezaz
The diversity of genome sizes across the tree of life is of key interest in evolutionary biology. Various correlates of variation in genome size, such as accumulation of transposable elements or rate of DNA gain and loss, are well known, but the underlying molecular mechanisms that drive or constrain genome size are poorly understood. Here we study one of the smallest genomes among frogs characterized thus far, that of the ornate burrowing frog (Platyplectrum ornatum)...

Neural signatures of vigilance decrements predict behavioural errors before they occur

Hamid Karimi-Rouzbahani, Alexandra Woolgar & Anina Rich
Abstract- There are many monitoring environments, such as railway control, in which lapses of attention can have tragic consequences. Problematically, sustained monitoring for rare targets is difficult, with more misses and longer reaction times over time. What changes in the brain underpin these “vigilance decrements”? We designed a multiple-object monitoring (MOM) paradigm to examine how the neural representation of information varied with target frequency and time performing the task. Behavioural performance decreased over time for...

Evaluating evidence of mitonuclear incompatibilities with the sex chromosomes in an avian hybrid zone

Daniel Hooper, Kelsie A Lopez, Callum S McDiarmid, Simon Griffith & Irby Lovette
The exploration of hybrid zones and the intergenomic conflicts exposed through hybridization provide windows into the processes of divergence and speciation. Sex chromosomes and mitonuclear incompatibilities have strong associations with the genetics of hybrid dysfunction. In ZW sex-determining systems, maternal co-inheritance of the mitochondrial and W chromosomes immediately exposes incompatibilities between these maternal contributions of one species and the Z chromosome of another. We analyze mitochondrial and Z chromosome admixture in the long-tailed finch (Poephila...

Avian vampire fly (Philornis downsi) intensity and mortality

Lauren K Common, Petra Sumasgutner, Rachael Y Dudaniec, Diane Colombelli-Negrel & Sonia Kleindorfer
In invasive parasites, generalism is considered advantageous during the initial phase of introduction. Thereafter, fitness costs to parasites, such as host-specific mortality, can drive parasites towards specialism to avoid costly hosts. It is important to determine changes in host specificity of invasive populations to understand host-parasite dynamics and their effects on vulnerable host populations. We examined changes in mortality in the introduced avian vampire fly (Philornis downsi) (Diptera: Muscidae), a generalist myasis-causing ectoparasite, between 2004...

Diet shift in a non-anadromous salmon: the effect of length on increased piscivorous feeding and trophic position.

Daniel Johnson & Drew Allen
Trophic ecology via isotope analysis is a functional way to predict the position of a consumer within the ecosystem it inhabits (Post, 2002). For this study, I aim to define trophic position changes and fish predation or piscivorous feeding in relation to size increase in a population of non-anadromous kokanee salmon (Oncorhynchus nerka), in the Jo-Jo Lake of south-west Alaska. Previous studies have shown these fish to exhibit planktivorous feeding, with some exceptions (Nelson JS,...

The aims of this scoping review are to first, identify the current literature investigating mental health literacy of primary school teachers; second, describe any available evidence-based interventions including how they were designed and by whom; and finally, provide recommendations for future research in this area.

A fossil-calibrated time-tree of all Australian freshwater fishes

Amy Tims, Simon Ho & Peter Unmack
Australian freshwater fishes are a relatively species-poor assemblage, comprising a small number of Gondwanan lineages and a number of groups derived from repeated freshwater invasions by marine ancestors. In addition to being a comparatively small assemblage, they are both highly endemic and highly threatened. However, a comprehensive phylogeny for these taxa is lacking, which has hampered efforts to study their phylogenetic diversity, distribution of extinction risk, speciation rate, and rates of trait evolution. Here, we...

Rates of attraction of cane toad tadpoles to chemicals

Richard Shine
Chemical cues produced by late-stage embryos of the cane toad (Rhinella marina) attract older conspecific larvae, which are highly cannibalistic and can consume an entire clutch. To clarify the molecular basis of this attraction response, we presented captive tadpoles with components present in toad eggs. As previously reported, attractivity arises from the distinctive toxins (bufadienolides) produced by cane toads, with some toxins (e.g., bufagenins) much stronger attractants than others (e.g., bufotoxins). Extracts of frozen toad...
