Data from: Logging and fire regimes alter plant communities

Elle J. Bowd, David B. Lindenmayer, Sam C. Banks & David P. Blair
Disturbances are key drivers of plant community composition, structure and function. Plant functional traits, including life forms and reproductive strategies are critical to the resilience and resistance of plant communities in the event of disturbance. Climate change and increasing anthropogenic disturbance are altering natural disturbance regimes, globally. When these regimes shift beyond the adaptive resilience of plant functional traits, local populations and ecosystem functions can become compromised. We tested the influence of multiple disturbances, of...

Data from: More partners, more ranges: generalist legumes spread more easily around the globe

Tia L. Harrison, Anna K. Simonsen, John R. Stinchcombe & Megan E. Frederickson
How does mutualism affect range expansion? On one hand, mutualists might thrive in new habitats thanks to the resources, stress tolerance, or defense provided by their partners. On the other, specialized mutualists might fail to find compatible partners beyond their range margins, limiting further spread. A recent global analysis of legume ranges found that non-symbiotic legumes have been successfully introduced to more ranges than legumes that form symbioses with rhizobia, but there is still abundant...

Data from: Taxon cycle predictions supported by model-based inference in Indo-Pacific trap-jaw ants (Hymenoptera: Formicidae: Odontomachus)

Pável Matos-Maraví, Nicholas J. Matzke, Fredrick J. Larabee, Ronald M. Clouse, Ward C. Wheeler, Daniela Magdalena Sorger, Andrew V. Suarez & Milan Janda
Non-equilibrium dynamics and non-neutral processes, such as trait-dependent dispersal, are often missing from quantitative island biogeography models despite their potential explanatory value. One of the most influential non-equilibrium models is the taxon cycle, but it has been difficult to test its validity as a general biogeographical framework. Here, we test predictions of the taxon-cycle model using six expected phylogenetic patterns and a time-calibrated phylogeny of Indo-Pacific Odontomachus (Hymenoptera: Formicidae: Ponerinae), one of the ant genera...

Data from: How to quantify (the response to) sexual selection on traits

Jonathan M. Henshaw, Michael D. Jennions & Loeske E. B. Kruuk
Natural selection operates via fitness components like mating success, fecundity and longevity, which can be understood as intermediaries in the causal process linking traits to fitness. Sexual selection occurs when traits influence mating or fertilisation success, which, in turn, influences fitness. We show how to quantify both these steps in a single path analysis, leading to better estimates of the strength of sexual selection. Our model controls for confounding variables, such as body size or...

Data from: Diversification across biomes in a continental lizard radiation

Lauren G. Ashman, Jason G. Bragg, Paul Doughty, Mark Norman Hutchinson, Sarah Bank, Nick Matzke, Paul M. Oliver, Craig Moritz, N. J. Matzke & P. Oliver
Ecological opportunity is a powerful driver of evolutionary diversification, and predicts rapid lineage and phenotypic diversification following colonisation of competitor-free habitats. Alternatively, topographic or environmental heterogeneity could be key to generating and sustaining diversity. We explore these hypotheses in a widespread lineage of Australian lizards: the Gehyra variegata group. This clade occurs across two biomes: the Australian monsoonal tropics (AMT), where it overlaps a separate, larger bodied clade of Gehyra and is largely restricted to...

Data from: Guidelines and considerations for designing field experiments simulating precipitation extremes in forest ecosystems

Heidi Asbjornsen, John L. Campbell, Katie A. Jennings, Matthew A. Vadeboncoeur, Cameron McIntire, Pamela H. Templer, Richard P. Phillips, Taryn L. Bauerle, Michael C. Dietze, Serita D. Frey, Peter M. Groffman, Rosella Guerrieri, Paul J. Hanson, Eric P. Kelsey, Alan K. Knapp, Nathan G. McDowell, Patrick Meir, Kimberly A. Novick, Scott V. Ollinger, Will T. Pockman, Paul G. Schaberg, Stan D. Wullschleger, Melinda D. Smith & Lindsey E. Rustad
1. Context. Precipitation regimes are changing in response to climate change, yet understanding of how forest ecosystems respond to extreme droughts and pluvials remains incomplete. As future precipitation extremes will likely fall outside the range of historical variability, precipitation manipulation experiments (PMEs) are critical to advancing knowledge about potential ecosystem responses. However, few PMEs have been conducted in forests compared to short-statured ecosystems, and forest PMEs have unique design requirements and constraints. Moreover, past forest...

Data from: Matching symbiotic associations of an endangered orchid to habitat to improve conservation outcomes

Noushka Reiter, Ann C. Lawrie & Celeste C. Linde
Background and Aims: An understanding of mycorrhizal variation, orchid seed germination temperature and the effect of co-occurring plant species could be critical for optimising conservation translocation of endangered plants with specialised mycorrhizal associations. Methods: Focussing on the orchid Thelymitra epipactoides we isolated mycorrhizal fungi from ten plants within each of three sites; Shallow Sands Woodland (SSW), Damp Heathland (DH) and Coastal Heathland Scrub (CHS). Twenty-seven fungal isolates were tested for symbiotic germination under three temperature...

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: Transgenerational effects of maternal sexual interactions in seed beetles

Susanne R.K. Zajitschek, Damian K. Dowling, Megan L. Head, Eduardo Rodriguez-Exposito & Francisco Garcia-Gonzalez
Mating bears large costs to females, especially in species with high levels of sexual conflict over mating rates. Given the direct costs to females associated with multiple mating, which include reductions in lifespan and lifetime reproductive success, past research focused on identifying potential indirect benefits (through increases in offspring fitness) that females may accrue. Far less attention has been given to understanding how costs of sexual interactions to females may span across generations. Hence, little...

Data from: The unexpected genetic mating system of the red‐backed toadlet (Pseudophryne coriacea): a species with prolonged terrestrial breeding and cryptic reproductive behaviour

Daniel M. O'Brien, J. Scott Keogh, Aimee J. Silla & Phillip G. Byrne
Molecular technologies have revolutionised our classification of animal-mating systems, yet we still know very little about the genetic-mating systems of many vertebrate groups. It is widely believed that anuran amphibians have the highest reproductive diversity of all vertebrates, yet genetic mating systems have been studied in less than one percent of all described species. Here, we use SNPs to quantify the genetic-mating system of the terrestrial breeding red-backed toadlet Pseudophryne coriacea. In this species, breeding...

Data from: From unburnt to salvage logged: quantifying bird responses to different levels of disturbance severity

David B. Lindenmayer, Lachlan McBurney, David Blair, Jeff Wood & Sam C. Banks
1. Forests worldwide are increasingly subject to natural and human disturbances, including wildfires and logging of varying intensity and frequency. Understanding how biodiversity responds to different kinds and combinations of natural and human disturbance is critical to enhanced forest management. 2. We completed an eight-year study of bird responses across a spectrum of disturbance types in Australian Mountain Ash (Eucalyptus regnans) forests following wildfires in 2009. 3. We found evidence of a gradient in bird...

Data from: The global geography of human subsistence

Michael C. Gavin, Patrick H. Kavanagh, Hannah J. Haynie, Claire Bowern, Carol R. Ember, Russell D. Gray, Fiona M. Jordan, Kathryn R. Kirby, Geoff Kushnick, Bobbi S. Low, Bruno Vilela & Carlos A. Botero
How humans obtain food has dramatically reshaped ecosystems and altered both the trajectory of human history and the characteristics of human societies. Our species’ subsistence varies widely, from predominantly foraging strategies, to plant-based agriculture and animal husbandry. The extent to which environmental, social, and historical factors have driven such variation is currently unclear. Prior attempts to resolve long-standing debates on this topic have been hampered by an over-reliance on narrative arguments, small and geographically-narrow samples,...

Data from: Good parenting may not increase reproductive success under environmental extremes

Rebecca J. Fox, Megan L. Head & Iain Barber
For species exhibiting parental care, the way in which parents adjust care behaviour to compensate for environmental change potentially influences offspring survival and, ultimately, population viability. Using the three-spined stickleback (Gasterosteus aculeatus) – a species in which males provide parental care by building and tending a nest and fanning the eggs – we examined how low dissolved oxygen (DO) levels affect paternal care, embryo development and survival. While levels of nest tending were unaffected by...

Data from: Predation risk for reptiles is highest at remnant edges in agricultural landscapes

Nicole A. Hansen, Chloe F. Sato, Damian R. Michael, David B. Lindenmayer & Don A. Driscoll
Preventing biodiversity loss in fragmented agricultural landscapes is a global problem. The persistence of biodiversity within remnant vegetation can be influenced by an animal's ability to move through the farmland matrix between habitat patches. Yet, many of the mechanisms driving species occurrence within these landscapes are poorly understood, particularly for reptiles. We used scented and unscented plasticine lizard models and wildlife cameras to (a) estimate predation risk of reptiles in four farmland types (crop field,...

Data from: Host-plant dissections reveal contrasting distributions of Crematogaster ants and their symbionts in two myrmecophytic Macaranga species

Mickal Y.I. Houadria, Petr Klimes, Tom M. Fayle & Penny J. Gullan
1. Ant–plant mutualisms are among the most widespread and ecologically important insect–plant interactions in the tropics. The multitrophic mutualism involving Macaranga plants (Euphorbiaceae) and Crematogaster ants (Formicidae) is the most diverse in Southeast Asia. This interaction also includes trophobiotic scale insects (Coccidae) and nematodes inhabiting ant refuse piles. 2. Here we compared two myrmecophytic systems, Macaranga trachyphylla with Crematogaster captiosa (Mt+Cc) and M. beccariana with C. decamera (Mb+Cd), using a fine-scale dissection of the stems....

Data from: Necrobiome framework for bridging decomposition ecology of autotrophically and heterotrophically derived organic matter

Mark Eric Benbow, Philip S. Barton, Michael D. Ulyshen, James C. Beasley, Travis L. DeVault, Michael S. Strickland, Jeffery K. Tomberlin, Heather R. Jordan & Jennifer L. Pechal
Decomposition contributes to global ecosystem function by contributing to nutrient recycling, energy flow and limiting biomass accumulation. The decomposer organisms influencing this process form diverse, complex, and highly dynamic communities that often specialize on different plant or animal resources. Despite performing the same net role, there is a need to conceptually synthesize information on the structure and function of decomposer communities across the spectrum of dead plant and animal resources. A lack of synthesis has...

Data from: Ageing with a silver-spoon: a meta-analysis of the effect of developmental environment on senescence

Eve B. Cooper, Loeske E.B. Kruuk & Loeske E. B. Kruuk
What determines variation between individuals in how they senesce, and are environmental conditions experienced during development relevant to late-life performance? We report a meta-analysis of studies of wild populations to determine how the quality of the environment experienced during development affects rates of survival and reproductive senescence. From studies of 14 bird or mammal species, we calculated effect sizes for the interaction between the effects of environmental quality during development and age in predicting survival...

Data from: Do migratory and resident birds differ in their responses to interacting effects of climate, weather and vegetation?

David B. Lindenmayer, Peter Lane, Claire N. Foster, Martin J. Westgate, Chloe Sato, Karen Ikin, Mason Crane, Damian Michael, Dan Florance, Ben C. Scheele & Daniel Florance
Aim: Knowledge of the individual and collective effects of habitat, weather variability, and climate on bird populations is limited, with the result that species vulnerability to the collective impacts of global change is poorly understood. We quantified the effects of interactions between these potential drivers on the occurrence of resident, migratory, and nomadic birds in Australian temperate woodlands. Location: A 1.8 million hectare temperate woodland belt in south-eastern Australia. Time period: 2002-2015. Major taxa studied:...

Data from: Effectiveness of camera traps for quantifying daytime and nighttime visitation by vertebrate pollinators

Siegfried L. Krauss, David G. Roberts, Ryan D. Phillips & Caroline Edwards
1. Identification of pollen vectors is a fundamental objective of pollination biology. The foraging and social behavior of these pollinators has profound effects on plant mating, making quantification of their behaviour critical for understanding the ecological and evolutionary consequences of different pollinators for the plants they visit. However, accurate quantification of visitation may be problematic, especially for shy animals and/or when the temporal and spatial scale of observation desired is large. Sophisticated heat- and movement-triggered...

Data from: Neurocranial anatomy of an enigmatic Early Devonian fish sheds light on early osteichthyan evolution

Alice M. Clement, Benedict King, Sam Giles, Brian Choo, Per Ahlberg, Gavin C. Young, John A. Long & Per E Ahlberg
The skull of ‘Ligulalepis’ from the Early Devonian of Australia (AM-F101607) has significantly expanded our knowledge of early osteichthyan anatomy, but its phylogenetic position has remained uncertain. We herein describe a second skull of ‘Ligulalepis’ and present micro-CT data on both specimens to reveal novel anatomical features, including cranial endocasts. Several features previously considered to link ‘Ligulalepis’ with actinopterygians are now considered generalized osteichthyan characters or of uncertain polarity. The presence of a lateral cranial...

Data from: Fluctuating selection and its (elusive) evolutionary consequences in a wild rodent population

Timothée Bonnet & Erik Postma
Temporal fluctuations in the strength and direction of selection are often proposed as a mechanism that slows down evolution, both over geological and contemporary time-scales. Both the prevalence of fluctuating selection and its relevance for evolutionary dynamics remain poorly understood however, especially on contemporary time scales: Unbiased empirical estimates of variation in selection are scarce, and the question of how much of the variation in selection translates into variation in genetic change has largely been...

Data from: A framework for resolving cryptic species: a case study from the lizards of the Australian Wet Tropics

Sonal Singhal, Conrad J. Hoskin, Patrick Couper, Sally Potter & Craig Moritz
As we collect range-wide genetic data for morphologically-defined species, we increasingly unearth evidence for cryptic diversity. Delimiting this cryptic diversity is challenging, both because the divergences span a continuum and because the lack of overt morphological differentiation suggests divergence has proceeded heterogeneously. Here, we address these challenges as we diagnose and describe species in three co-occurring species groups of Australian lizards. By integrating genomic and morphological data with data on hybridization and introgression from contact...

Data from: The microstructure of white feathers predicts their visible and near-infrared reflectance properties

Devi Stuart-Fox, Elizabeth Newton, Raoul A. Mulder, Liliana D'Alba, Matthew D. Shawkey, Branislav Igic & Liliana D’Alba
Research on the optical properties of animal integuments, including fur, feather, skin and cuticle, has focussed almost exclusively on animal-visible wavelengths within the narrow range of 300 - 700 nm. By contrast, the near-infrared (NIR) portion of direct sunlight, spanning 700 - 2600 nm, has been largely ignored despite its potentially important thermal consequences. We quantified variation in visible and NIR reflectance and transmission for white body contour feathers of 50 bird species, and examined...

Data from: Penguin ectoparasite panmixia suggests extensive host movement within a colony

Katherine L. Moon, Ceridwen I. Fraser, Steven L. Chown & Angela McGaughran
Parasite population structure can be used to infer fine-scale movement in host species. Many penguin species form large social colonies, and are highly philopatric, returning to the same nest or burrow, along the same route, after each trip to sea. Within a colony, however, the local abundance, physical similarity, and nocturnal habits of penguins hinder the observation of fine-scale movements. To determine the extent of movement and interaction of penguins within colonies, a genotyping by...

Data from: The disproportionate importance of long-unburned forests and woodlands for reptiles

Kelly M. Dixon, Geoffrey J. Cary, Graeme L. Worboys & Philip Gibbons
1. Our understanding of the impacts of time since fire on reptiles remains limited, partly because there are relatively few locations where long-term, spatially explicit fire histories are available. Such information is important given the large proportion of some landscapes that are managed with frequent prescribed fire to meet fuel management objectives. 2. We conducted a space-for-time study across a landscape in south-east Australia where the known fire history spanned 6 months to at least...
