Modelled mid-trophic pelagic prey fields improve understanding of marine predator foraging behaviour

David Green, Sophie Bestley, Rowan Trebilco, Stuart Corney, Patrick Lehodey, Clive McMahon, C. Guinet & Mark A. Hindell
Biophysical interactions are influential in determining the scale of key ecological processes within marine ecosystems. For oceanic predators, this means foraging behaviour is influenced by processes shaping the distribution of prey. However, oceanic prey is difficult to observe and its abundance and distribution is regionally generalised. We use a spatiotemporally resolved simulation model to describe mid-trophic prey distribution within the Southern Ocean and demonstrate insights that this modelled prey field provides into the foraging behaviour...

Does rapid utilisation of elevated nutrient availability allow eucalypts to dominate in the tropical savannas of Australia?

Harinandanan Paramjyothi, Brett Murphy, Michael Lawes, Natalie Rossitet-Rachor & Anna Richards
Northern Australia's savannas are amongst the most fire-prone biomes on Earth, and are dominated by eucalypts (Eucalyptus and Corymbia spp.). It is not clear what processes allows this group to dominate under such extreme fire frequencies and if a superior ability to compete for nutrients and water might play a role. There is evidence that eucalypts are adapted to frequent fires; juvenile eucalypts escape the fire trap by growing rapidly in height between fires. However,...

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...

Long non-coding RNA XIST promotes the progression of esophageal squamous cell carcinoma through sponging miR-129-5p and upregulating CCND1 expression

Haoran Wang, Haomiao Li, Yongkui Yu, Qingfeng Jiang, Ruixiang Zhang, Haibo Sun, Wenqun Xing & Yin Li
Long non-coding RNA (lncRNA) X inactive specific transcript (XIST) has been identified as an oncogenic lncRNA in a series of human cancers, including esophageal squamous cell carcinoma (ESCC). In this study, we aimed to further explore the underlying mechanism of XIST on ESCC progression. qRT-PCR assay was used to determine the levels of XIST and miR-129-5p. Western blot analysis was performed to assess cyclin D1 (CCND1) expression. Bioinformatic analysis was performed using starBase v2.0 software....

Data from: Oxidative stress delays development and alters gene expression in the agricultural pest moth, Helicoverpa armigera

, Bill James, Karl Gordon, Tom Walsh & Angela McGaughran
Stress is a widespread phenomenon that all organisms must endure. Common in nature is oxidative stress, which can interrupt cell homeostasis to cause cell damage and may be derived from respiration or from environmental exposure through diet. As a result of the routine exposure from respiration, many organisms can mitigate the effects of oxidative stress, but less is known about responses to oxidative stress from other sources. Helicoverpa armigera is a major agricultural pest moth...

Natural enemy-herbivore networks along local management and landscape gradients in urban agroecosystems

Stacy Philpott, Azucena Lucatero, Peter Bichier, Monika Egerer, Shalene Jha, Brenda Lin & Heidi Liere
Ecological networks can provide insight into how biodiversity loss and changes in species interactions impact the delivery of ecosystem services. In agroecosystems that vary in management practices, quantifying changes in ecological network structure across gradients of local and landscape composition can inform both the ecology and function of productive agroecosystems. In this study, we examined natural enemy-herbivore co-occurrence networks associated with Brassica oleracea (cole crops), a common crop in urban agricultural systems. Specifically, we investigated...

Data from: Parallel evolution of bower-building behavior in two groups of bowerbirds suggested by phylogenomics

Per G. P. Ericson, Martin Irestedt, Johan A. A. Nylander, Les Christidis, Leo Joseph & Yanhua Qu
The bowerbirds in New Guinea and Australia include species that build the largest and perhaps most elaborately decorated constructions outside of humans. The males use these courtship bowers, along with their displays, to attract females. In these species, the mating system is polygynous and the females alone incubate and feed the nestlings. The bowerbirds also include 10 species of the socially monogamous catbirds in which the male participates in most aspects of raising the young....

Analysis of RNA-seq, DNA target enrichment, and Sanger nucleotide sequence data resolves deep splits in the phylogeny of cuckoo wasps (Hymenoptera: Chrysididae)

Thomas Pauli, Karen Meusemann, Sandra Kukowka, Manuela Sann, Alexander Donath, Christoph Mayer, Jan Philip Oeyen, Yolanda Ballesteros, Alexander Berg, Eric Van Den Berghe, Hermes Escalona, Adalgisa Guglielmino, Manfred Niehuis, Massimo Olmi, Lars Podsiadlowski, Carlo Polidori, Jeroen De Rond, Paolo Rosa, Thomas Schmitt, Franco Strumia, Mareike Wurdack, Shanlin Liu, Xin Zhou, Bernhard Misof, Ralph Peters … & Oliver Niehuis
The wasp family Chrysididae (cuckoo wasps, gold wasps) comprises exclusively parasitoid and kleptoparasitic species, many of which feature a stunning iridescent coloration and phenotypic adaptations to their parasitic life style. Previous attempts to infer phylogenetic relationships among the family’s major lineages (subfamilies, tribes, genera) based on Sanger sequence data were insufficient to statistically resolve the monophyly and the phylogenetic position of the subfamily Amiseginae and the phylogenetic relationships among the tribes Allocoeliini, Chrysidini, Elampini, and...

These changes will occur at global, national, and local scales. They will create opportunities and challenges for all food and fibre industries and farm businesses. They will also impact on Australian lifestyles, landscapes, communities, and wider society and economy. In order to better understand these evolving changes, this report...

Maintenance of variation in virulence and reproduction in populations of an agricultural plant pathogen

Anik Dutta, Daniel Croll, Bruce A. McDonald & Luke G. Barrett
Genetic diversity within pathogen populations is critically important for predicting pathogen evolution, disease outcomes, and prevalence. However, we lack a good understanding of the processes maintaining genetic variation and constraints on pathogen life‐history evolution. Here, we analyzed interactions between 12 wheat host genotypes and 145 strains of Zymoseptoria tritici from five global populations to investigate the evolution and maintenance of variation in pathogen virulence and reproduction. We found a strong positive correlation between virulence (amount...

Around the world in 10 million years: rapid dispersal of a kleptoparasitoid spider wasp (Pompilidae: Ceropales)

Juanita Rodriguez, Sarah Bank, Cecilia Waichert, Carol Von Dohlen & James Pitts
Aim: Our aim was to estimate the historical biogeography of the kleptoparasitoid genus Ceropales and to determine the processes leading to its current worldwide distribution. We tested hypotheses of dispersal and vicariance scenarios underlying its widespread distribution. Location: Worldwide. Methods: Data from two nuclear markers (the D2–D3 regions of the 28S ribosomal RNA and long-wavelength rhodopsin) and one mitochondrial marker (cytochrome c oxidase I) for 52 specimens of Ceropales were used to reconstruct a dated...

Evolving thermal thresholds explain the distribution of temperature sex reversal in an Australian dragon lizard

Meghan Castelli, Arthur Georges, Caitlin Cherryh, Dan Rosauer, Stephen Sarre, Isabella Contador-Kelsall & Clare Holleley
Aim: Species with temperature-dependent sex determination (TSD) are particularly vulnerable to climate change because a resultant skew in population sex ratio can have severe demographic consequences and increase vulnerability to local extinction. The Australian central bearded dragon (Pogona vitticeps) has a thermosensitive ZZ male/ZW female system of genetic sex determination (GSD). High incubation temperatures cause reversal of the ZZ genotype to a viable female phenotype. Nest temperatures in the wild are predicted to vary on...

Identification of Y chromosome markers in the eastern three-lined skink (Bassiana duperreyi) using in silico whole genome subtraction

Duminda Dissanayake, Clare Holleley & Arthur Georges
Background: Homologous sex chromosomes can differentiate over time because recombination is suppressed in the region of the sex determining locus, leading to the accumulation of repeats, progressive loss of genes that lack differential influence on the sexes and sequence divergence on the hemizygous homolog. Divergence in the non-recombining regions leads to the accumulation of Y or W specific sequence useful for developing sex-linked markers. Here we use in silico whole-genome subtraction to identify putative sex-linked...
