Data from: Sexual selection across sensory modalities: female choice of male behavioral and gustatory displays

Jacob D. Berson & Leigh W. Simmons
The role of cuticular hydrocarbons in sexual displays has received considerable interest over the last two decades. For example, multiple studies have documented significant directional and nonlinear sexual selection acting on the cuticular hydrocarbon profiles of both male and female insects. The majority of these studies have excluded other sensory modalities that may influence attractiveness, and measured selection using laboratory raised individuals. Furthermore, much of this work has been conducted using drosophilid fruit flies and...

Data from: Biotic and abiotic plant-soil feedback depends on nitrogen-acquisition strategy and shifts during long-term ecosystem development

Guochen Kenny Png, Hans Lambers, Paul Kardol, Benjamin L. Turner, David A. Wardle & Etienne Laliberté
1. Feedback between plants and soil is an important driver of plant community structure, but it remains unclear whether plant-soil feedback (PSF): (i) reflects changes in biotic or abiotic properties, (ii) depends on environmental context in terms of soil nutrient availability, and (iii) varies among plant functional groups. Because soil nutrient availability strongly affects plant distribution and performance, soil chemical properties and plant nutrient-acquisition strategies might serve as important drivers of PSF. 2. We used...

Data from: Individual dispersal decisions in a cooperative breeder: ecological constraints, the benefits of philopatry, and the social queue for dominance

Martha J. Nelson-Flower, Elizabeth M. Wiley, Thomas P. Flower, Amanda R. Ridley & Tom P. Flower
1. Delayed dispersal is a key step in the evolution of familial animal societies and cooperative breeding. However, no consensus has been reached on the ecological and social circumstances driving delayed dispersal. 2. Here we test predictions from the ecological constraints and benefits of philopatry hypotheses as well as the recently-proposed dual benefits hypothesis to better understand the evolution of group-living and cooperative breeding. Furthermore, we consider how individual social circumstances within groups affect dispersal...

Data from: Environmental DNA metabarcoding studies are critically affected by substrate selection

Adam Koziol, Michael Stat, Tiffany Simpson, Simon Jarman, Joseph D. DiBattista, Euan S. Harvey, Michael Marnane, Justin McDonald & Michael Bunce
Effective biomonitoring is critical for driving management outcomes that ensure long-term sustainability of the marine environment. In recent years environmental DNA (eDNA), coupled with metabarcoding methodologies, has emerged as a promising tool for generating biotic surveys of marine ecosystems, including those under anthropogenic pressure. However, more empirical data is needed on how to best implement eDNA field sampling approaches to maximise their utility for each specific application. The effect of the substrate chosen for eDNA...

Data from: A competitive environment influences sperm production, but not testes tissue composition, in house mice

Renée C. Firman, Francisco Garcia-Gonzalez, Leigh W. Simmons & Goncalo I. Andre
Due to the physiological cost of sperm production, males are expected to be prudent in their expenditure and adjust their investment according to current social conditions. Strategic adjustments in sperm expenditure during development can be made via changes in testes size, sperm production rates, or testes tissue composition. Here, using house mice, we test the hypothesis that elevated sperm production is driven by a plastic response in the spatial organisation of the testes. We reared...

Data from: Female control over multiple matings increases the opportunity for postcopulatory sexual selection

Clelia Gasparini & Jonathan P. Evans
It is widely acknowledged that in most species sexual selection continues after mating. Although it is generally accepted that females play an important role in generating paternity biases (i.e., cryptic female choice), we lack a quantitative understanding of the relative importance of female-controlled processes in influencing variance in male reproductive fitness. Here we address this question experimentally using the guppy Poecilia reticulata, a polyandrous fish in which pre- and postcopulatory sexual selection jointly determine male...

Data from: A comprehensive and user-friendly framework for 3D-data visualisation in invertebrates and other organisms

Thomas L. Semple, Rod Peakall & Nikolai J. Tatarnic
Methods for 3D‐imaging of biological samples are experiencing unprecedented development, with tools such as X‐ray micro‐computed tomography (μCT) becoming more accessible to biologists. These techniques are inherently suited to small subjects and can simultaneously image both external and internal morphology, thus offering considerable benefits for invertebrate research. However, methods for visualising 3D‐data are trailing behind the development of tools for generating such data. Our aim in this article is to make the processing, visualisation and...

Data from: A costly chemical trait: phenotypic condition dependence of cuticular hydrocarbons in a dung beetle

Jacob D. Berson & Leigh W. Simmons
Chemical traits are increasingly recognised as important cues used in mate choice. For example, the cuticular hydrocarbons (CHCs) of insects have been shown to influence mating success in a range of taxa. Less is known, however, about how CHCs are expressed in proportion to an individual’s condition, and consequently whether CHCs can function as condition dependent signals of quality. We investigated this question using the dung beetle, Onthophagus taurus. CHCs are subject to sexual selection...

Data from: Social cues affect quantitative genetic variation and covariation in animal personality traits

Fabian Sandro Rudin, Leigh W. Simmons & Joseph L. Tomkins
The social environment is expected to have substantial effects on behavior, and as a consequence its heritability and evolvability. We investigated these effects by exposing Australian field crickets (Teleogryllus oceanicus) to either silence or recordings of male acoustic sexual signals. We used a combined pedigree and full-sib/half-sib breeding design to estimate the repeatability, heritability, and evolvability of behaviors related to boldness, exploration, and activity. All behaviors measured were significantly repeatable in both social environments. Additionally,...

Data from: Genome sequencing and analysis of the peanut b-genome progenitor (Arachis ipaensis)

Qing Lu, Haifen Li, Yanbin Hong, Guoqiang Zhang, Shijie Wen, Xingyu Li, Guiyuan Zhou, Shaoxiong Li, Hao Liu, Haiyan Liu, Zhongjian Liu, Rajeev K. Varshney, Xiaoping Chen & Xuanqiang Liang
Peanut (Arachis hypogaea L.), an important leguminous crop, is widely cultivated in tropical and subtropical regions. Peanut is an allotetraploid, having A and B subgenomes that maybe have originated in its diploid progenitors Arachis duranensis (A-genome) and Arachis ipaensis (B-genome), respectively. We previously sequenced the former and here present the draft genome of the latter, expanding our knowledge of the unique biology of Arachis. The assembled genome of A. ipaensis is ~1.39 Gb with 39,704...

Data from: Morph-specific artificial selection reveals a constraint on the evolution of polyphenisms

Bruno A. Buzatto, Huon L. Clark & Joseph L. Tomkins
Theory predicts that the evolution of polyphenic variation is facilitated where morphs are genetically uncoupled and free to evolve towards their phenotypic optima. However, the assumption that developmentally plastic morphs can evolve independently has not been tested directly. Using morph-specific artificial selection, we investigated correlated evolution between the sexes and male morphs of the bulb mite Rhizoglyphus echinopus. Large ‘fighter’ males have a thick and sharply terminating pair of legs used to kill rival males,...

Data from: Effect of plant root symbionts on performance of native woody species in competition with an invasive grass in multispecies microcosms

Christina Birnbaum, Tim K. Morald, Mark Tibbett, Richard G. Bennett & Rachel J. Standish
The majority of terrestrial plants form mutualistic associations with arbuscular mycorrhizal fungi (AMF) and rhizobia (i.e. nitrogen fixing bacteria). Understanding these associations has important implications for ecological theory and for restoration practice. Here we tested whether the presence of AMF and rhizobia influence the performance of native woody plants invaded by a non-native grass in experimental microcosms. We planted eight plant species (i.e. Acacia acuminata, A. microbotrya, Eucalyptus loxophleba subsp. loxophleba, E. astringens, Calothamnus quadrifidus,...

Data from: Plasticity in root symbioses following shifts in soil nutrient availability during long-term ecosystem development

François P. Teste & Etienne Laliberté
1. The vast majority of terrestrial plants form root symbioses with arbuscular mycorrhizal (AM) fungi to enhance nutrient (particularly phosphorus, P) acquisition, but some plant species also form dual symbioses involving ectomycorrhizal (ECM) fungi, with a subset of those also forming triple symbioses also involving dinitrogen (N2)-fixing bacteria. Whether these plants show plasticity in root symbioses to optimise nutrient acquisition depending on the type and strength of soil nutrient limitation (e.g., N vs. P) has...

Data from: Climate change impacts on marine biodiversity, fisheries and society in the Arabian Gulf

Daniel Pauly, Myriam Khalfallah, Dalal Al-Abdulrazzak, Lydia C. L. Teh, Gabriel Reygondeau, Colette C. C. Wabnitz, Maria L. Deng Palomares, Dirk Zeller, William W. L. Cheung & Vicky W. Y. Lam
Climate change - reflected in significant environmental changes such as warming, sea level rise, shifts in salinity, oxygen and other ocean conditions - is expected to impact marine organisms and associated fisheries. This study provides an assessment of the potential impacts on, and the vulnerability of, marine biodiversity and fisheries catches in the Arabian Gulf under climate change. To this end, using three separate niche modelling approaches under a 'business-as-usual' climate change scenario, we projected...

Data from: Multiple independent origins of intermediate species between Sorbus aucuparia and S. hybrida (Rosaceae) in the Baltic region

Joel Levin, Michael F. Fay, Jaume Pellicer & Mikael Hedrén
Populations intermediate between the diploid and sexual Sorbus aucuparia and the tetraploid and facultative apomictic Sorbus hybrida are scattered in coastal regions of southern Scandinavia. Our aims were to investigate whether these populations were of local and independent origins, whether they were morphologically and molecularly distinct from each other and whether they could give rise to constant offspring by apomixis. Six intermediate populations from the Baltic Sea basin were studied for variation at nuclear and...

Data from: Isolation and no-entry marine reserves mitigate anthropogenic impacts on grey reef shark behavior

Jean-Baptiste Juhel, Laurent Vigliola, Laurent Wantiez, Tom B. Letessier, Jessica J. Meeuwig & David Mouillot
Reef sharks are vulnerable predators experiencing severe population declines mainly due to overexploitation. However, beyond direct exploitation, human activities can produce indirect or sub-lethal effects such as behavioral alterations. Such alterations are well known for terrestrial fauna but poorly documented for marine species. Using an extensive sampling of 367 stereo baited underwater videos systems, we show modifications in grey reef shark (Carcharhinus amblyrhynchos) occurrence and feeding behavior along a marked gradient of isolation from humans...

Data from: The effect of uncertain bottom friction on estimates of tidal current power

Monika J. Kreitmair, Scott Draper, Alistair G.L. Borthwick & Ton S. Van Den Bremer
Uncertainty affects estimates of the power potential of tidal currents, resulting in large ranges in values reported for a given site, such as the Pentland Firth, UK. We examine the role of bottom friction, one of the most important sources of uncertainty. We do so by using perturbation methods to find the leading-order effect of bottom friction uncertainty in theoretical models by Garrett & Cummins (2005), Vennell (2010), and Garrett & Cummins (2013), which consider...

Data from: Seed moisture content as a primary trait regulating the lethal temperature thresholds of seeds.

Ryan Tangney, David J. Merritt, Joseph B. Fontaine & Ben P. Miller
1) Fire has shaped biological responses of plants and plant communities in fire-prone systems and is linked to myriad ecological processes but also frequently puts people and infrastructure at risk. Fuel or hazard-reduction burning is a common practice aimed at reducing the risk of high-severity fires, which ideally also incorporates consideration of biodiversity values. Within fire-prone systems, seed banks are often critical for plant species’ regeneration, and seeds are typically adapted to survive the passage...

Data from: Resistance of corals and coralline algae to ocean acidification: physiological control of calcification under natural pH variability

Christopher E. Cornwall, Steeve Comeau, Thomas M. DeCarlo, Billy Moore, Quentin D'Alexis & Malcolm T. McCulloch
Ocean acidification is a threat to the continued accretion of coral reefs, though some undergo daily fluctuations in pH exceeding declines predicted by 2100. We test whether exposure to greater pH variability enhances resistance to ocean acidification for the coral Goniopora sp. and coralline alga Hydrolithon reinboldii from two sites: one with low pH variability (< 0.15 units daily; Shell Island), and a site with high pH variability (up to 1.4 pH units daily; Tallon...
