Data for: Substantial intraspecific trait variation across a hydrological gradient in northern Australian fishes

Osmar Luiz, Julian Olden, Mark Kennard, David Crook, Michael Douglas, Thor Saunders, Dion Wedd, Brendan Adair & Alison King
Trait-based models of ecological communities and ecosystem functioning often fail to account for intraspecific variation in functional traits, assuming that intraspecific variability is negligible compared to interspecific variability. However, this assumption remains poorly tested across vertebrate animals where past studies routinely describe species according to mean trait values without explicit consideration of individual trait variability. We assessed nine functional traits for 4,254 individuals belonging to 15 freshwater fish species from 11 families in Northern Australia,...

Different genes are recruited during convergent evolution of pregnancy and the placenta

Charles Foster, James Van Dyke, Michael Thompson, Nicholas Smith, Colin Simpfendorfer, Christopher Murphy & Camilla Whittington
The repeated evolution of the same traits in distantly related groups (convergent evolution) raises a key question in evolutionary biology: do the same genes underpin convergent phenotypes? Here, we explore one such trait, viviparity (live birth), which, qualitative studies suggest, may indeed have evolved via genetic convergence. There are 150 independent origins of live birth in vertebrates, providing a uniquely powerful system to test the mechanisms underpinning convergence in morphology, physiology, and/or gene recruitment during...

Data from: Seasonal and functional variation in the trophic base of intermittent Alpine streams

Andre Siebers, Amael Paillex & Christopher Robinson
In high-altitude Alpine streams, seasonal cycles of snowmelt, glacial melt, and rainfall drive variation in the availability of algal food resources. Yet high-altitude streams also exhibit varying degrees of flow intermittency, from solely winter-drying streams to others that dry periodically throughout summer and autumn. These environmental drivers may interact in different ways to determine the functional trophic base of macroinvertebrates inhabiting high-altitude streams. Here, we estimated the proportional contribution of autochthonous resources to the assimilated...

MO2, behaviour data and supplementary material for the first physiological evidence of sleep in sharks

Michael Kelly, Selwyn Collins, John Lesku, Jan Hemmi, Shaun Collin & Craig Radford
Sharks represent the earliest group of jawed vertebrates and as such, they may provide original insight for understanding the evolution of sleep in more derived animals. Unfortunately, beyond a single behavioural investigation, very little is known about sleep in these ancient predators. As such, recordings of physiological indicators of sleep in sharks have never been reported. Reduced energy expenditure arising from sustained restfulness and lowered metabolic rate during sleep have given rise to the hypothesis...

Data from: Low-cost automated flight intercept trap for the temporal sub-sampling of flying insects attracted to artificial light at night

Kylie Robert, Alicia Dimovski, Joel Robert & Stephen Griffiths
Sampling methods are selected depending on the targeted species or the spatial and temporal requirements of the study. However, most methods for passive sampling of flying insects have poor temporal resolution because it is time consuming, costly and/or logistically difficult. Effective sampling of flying insects attracted to artificial light at night (ALAN) requires sampling at user-defined time points (nighttime only) across well-replicated sites resulting in major time and labor-intensive survey effort or expensive automated technologies....

Diverse parentage relationships in paternal mouth-brooders

Janine Abecia, Alison King, Osmar Luiz, David Crook, Dion Wedd & Sam Banks
While mouthbrooding is not an uncommon parental care strategy in fishes, paternal mouthbrooding only occurs in eight fish families and little studied. The high cost of paternal mouthbrooding to the male implies a low risk of investment in another male’s offspring but genetic parentage patterns are poorly known for paternal mouthbrooders. Here we used single nucleotide polymorphism (SNP) genetic data to investigate parentage relationships of broods of two mouthbrooders of northern Australian rivers, mouth almighty...

Birds and insects respond differently to combinations of semi-natural features in farm landscapes

Mark Hall, Dale Nimmo & Andrew F Bennett
Semi-natural features among farmland have a key role in maintaining wildlife in rural landscapes. Practical conservation requires knowledge of which combinations of features are of greatest value and whether this differs among faunal groups. We used a ‘landscape’ approach to investigate the relative importance to birds and insects (bees, flies, wasps) of combinations of three wooded features typical of farmland in south-eastern Australia: scattered trees, wooded roadsides and wooded streamside vegetation. We selected 44 landscapes...

Morphometric analysis of lungfish endocasts elucidates early dipnoan palaeoneurological evolution

Alice Clement, Tom Challands, Richard Cloutier, Laurent Houle, Per Ahlberg, Shaun Collin & John Long
Lungfish (Dipnoi) are lobe-finned fish (Sarcopterygii) that have persisted for over 400 million years from the Devonian Period to present day. They are the extant sister group to tetrapods and thus have the ability to provide unique insight into the condition of the earliest tetrapods as well as their own evolutionary history. The evolution of their dermal skull and dentition is relatively well understood, but this is not the case for the central nervous system....

Calculating bond dissociation energies of X-H (X = C, N, O, S) bonds of aromatic systems via DFT: A detailed comparison of methods

Quan V. Vo, Adam Mechler, Nguyen Thi Hoa & Nguyen Quang Trung
In this study, the bond dissociation energy (BDE) values of X-H (X = C, N, O, S) bonds of aromatic compounds were computed by using 17 different DFT functionals, namely M08-HX, M06-2X, M05-2X, M06, M05, BMK, MPW1B95, B1B95, B98, B97-2, LC-wPBE, B3LYP, cam-B3LYP, B2PLYP, MPWB1K, BB1K, BB95, within the basis set range 6-31G(d), 6-31+G(d), 6-31+G(d,p), 6-311G(d,p) and 6-311++G(d,p). The results show that the 6-31G(d) is the most convenient basis set to perform the BDE calculations...

Can fire-age mosaics really deal with conflicting needs of species? A study using population hotspots of multiple threatened birds

Simon Verdon & Michael Clarke
Locations that support high densities of a species (“population hotspots”) have a disproportionate influence on species’ persistence. In fire-prone ecosystems, managers attempting to promote population hotspots of multiple species must understand how hotspot locations might shift with post-fire succession and how much overlap exists in the locations of population hotspots for multiple species. Mangers are then tasked with resolving fire-management conflicts in overlapping locations. We studied three co-occurring threatened bird species in a fire-prone ‘mallee’...

Sex-specific splicing of Z- and W-borne nr5a1 alleles suggests sex determination is controlled by chromosome conformation

Xiuwen Zhang, Susan Wagner, Clare Holleley, Janine Deakin, Kazumi Matsubara, Ira Deveson, Deni O'Meally, Hardip Patel, Tariq Ezaz, Zhao Li, Chexu Wang, Melanie Edwards, Jennifer Marshall Graves & Arthur Georges
Pogona vitticeps has female heterogamety (ZZ/ZW) but the master sex determining gene is unknown, as is the case for all reptiles. We show that nr5a1, a gene that is essential in mammalian sex determination, has alleles on the Z and W chromosomes (Z-nr5a1 and W-nr5a1), which are both expressed and can recombine. Three transcript isoforms of Z-nr5a1 were detected in gonads of adult ZZ males, two of which encode a functional protein. However, ZW females...

The global distribution of known and undiscovered ant biodiversity

Jamie Kass, Benoit Guénard, Kenneth Dudley, Clinton Jenkins, Fumika Azuma, Brian Fisher, Catherine Parr, Heloise Gibb, John Longino, Philip Ward, Anne Chao, David Lubertazzi, Michael Weiser, Walter Jetz, Robert Guralnick, Rumsaïs Blatrix, James Des Lauriers, David Donoso, Christos Georgiadis, Kiko Gomez, Peter Hawkes, Robert Johnson, John Lattke, Joe MacGown, William Mackay … & Evan Economo
Invertebrates constitute the majority of animal species and are critical for ecosystem functioning and services. Nonetheless, global invertebrate biodiversity patterns and their congruences with vertebrates remain largely unknown. We resolve the first high-resolution (~20-km) global diversity map for a major invertebrate clade, ants, using biodiversity informatics, range modeling, and machine learning to synthesize existing knowledge and predict the distribution of undiscovered diversity. We find that ants and different vertebrate groups have distinct features in their...
