Data from: High intra-specific variation in avian body condition responses to climate limits generalisation across species

Nina McLean, Henk P. Van Der Jeugd & Martijn Van De Pol
It is generally assumed that populations of a species will have similar responses to climate change, and thereby that a single value of sensitivity will reflect species-specific responses. However, this assumption is rarely systematically tested. High intraspecific variation will have consequences for identifying species- or population-level traits that can predict differences in sensitivity, which in turn can affect the reliability of projections of future climate change impacts. We investigate avian body condition responses to changes...

Data from: Dating the species network: allopolyploidy and repetitive DNA evolution in American daisies (Melampodium sect. Melampodium, Asteraceae)

Jamie McCann, Tae-Soo Jang, Jiri Macas, Gerald M. Schneeweiss, Nicholas J. Matzke, Petr Novak, Tod F. Stuessy, Jose L. Villaseñor & Hanna Weiss-Schneeweiss
Allopolyploidy has played an important role in the evolution of the flowering plants. Genome mergers are often accompanied by significant and rapid alterations of genome size and structure via chromosomal rearrangements and altered dynamics of tandem and dispersed repetitive DNA families. Recent developments in sequencing technologies and bioinformatic methods allow for a comprehensive investigation of the repetitive component of plant genomes. Interpretation of evolutionary dynamics following allopolyploidization requires both the knowledge of parentage and the...

Data from: New information on Brindabellaspis stensioi Young, 1980, highlights morphological disparity in Early Devonian placoderms

Benedict King, Gavin C. Young & John A. Long
Acid prepared specimens of the placoderm Brindabellaspis stensioi (Early Devonian of New South Wales, Australia) revealed placoderm endocranial anatomy in unprecedented detail. Brindabellaspis has become a key taxon in discussions of early gnathostome phylogeny, and the question of placoderm monophyly versus paraphyly. The anterior orientation of the facial nerve and related hyoid arch structures in this taxon resemble fossil osteostracans (jawless vertebrates) rather than other early gnathostomes. New specimens of Brindabellaspis now reveal the previously...

Data from: True recognition of nestlings by hosts selects for mimetic cuckoo chicks

Hee-Jin Noh, Ros Gloag & Naomi E. Langmore
Cuckoos lay their eggs in other birds’ nests, whereafter the young cuckoo hatches, ejects its nestmates, and monopolizes the care of the host parents. Theory predicts that hosts should not evolve to recognize and reject cuckoo chicks because of the risk of mistakenly imprinting on a cuckoo chick in their first brood and thereafter always rejecting their own chicks. However, recent studies have revealed some hosts do reject cuckoo chicks from the nest, indicating that...

Data from: Insular biogeographic origins and high phylogenetic distinctiveness for a recently depleted lizard fauna from Christmas Island, Australia

Paul M. Oliver, Mozes P.K. Blom, Harold G. Cogger, Robert N. Fisher, Jonathan Q. Richmond, John C.Z. Woinarski & John C. Z. Woinarski
Striking faunal turnover across Asia and Australasia, most famously along the eastern edge of the Sunda Shelf or ‘Wallace’s Line’, has been a focus of biogeographic research for over 150 years. Here we investigate the origins of a highly threatened endemic lizard fauna (4 species) on Christmas Island. Despite occurring less 350 km south of the Sunda Shelf, this fauna mostly comprises species from clades centred on the more distant regions of Wallacea, the Pacific...

Data from: Phylogenomics of a rapid radiation: the Australian rainbow skinks

Jason G. Bragg, Sally Potter, Ana C. Afonso Silva, Conrad J. Hoskin, Benjamin Y.H. Bai & Craig Moritz
Background: The application of target capture with next-generation sequencing now enables phylogenomic analyses of rapidly radiating clades of species. But such analyses are complicated by extensive incomplete lineage sorting, demanding the use of methods that consider this process explicitly, such as the multi-species coalescent (MSC) model. However, the MSC makes strong assumptions about divergence history and population structure, and when using the full Bayesian implementation, current computational limits mean that relatively few loci and samples...

Data from: Environmental resource deficit may drive the evolution of intraspecific trait variation in invasive plant populations

Shuangshuang Liu, Jared Streich, Justin O. Borevitz, Kevin J. Rice, Tingting Li, Bo Li & Kent J. Bradford
Intraspecific trait variation within natural populations (i.e. intra‐population trait variation, IPTV) is the basic source for selection and can have significant ecological consequences. Higher IPTV may increase a population's niche breath and benefit interspecies competition under a resource‐limited environment, thus affecting the ability of a species to move into novel habitats. However, the reciprocal influences of variation in environmental conditions and phenotypic trait expression in spreading plant populations are not clearly defined. We propose that...

Data from: A new actinopterygian from the Late Devonian Gogo Formation, Western Australia

Brian Choo, Jing Lu, Sam Giles, Kate Trinajstic & John A. Long
The study of early actinopterygians (ray-finned fishes) from the Devonian has been hampered by imperfect preservation in the majority of taxa. The Late Devonian (early Frasnian) Gogo Formation of north-western Western Australia is notable in producing complete fossil actinopterygians with exceptional three-dimensional preservation of both the dermal and endoskeletal anatomy. Four taxa have been described and have proved invaluable in understanding the anatomy of early representatives of this clade. Here, we present a fifth Gogo...

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: 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...

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: 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: 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: 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: 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: Shock and stabilisation following long-term drought in tropical forest from 15 years of litterfall dynamics

Lucy Rowland, Antonio C. L. Da Costa, Alex A. R. Oliveira, Samuel S. Almeida, Leandro V. Ferreira, Yadvinder Malhi, Dan B. Metcalfe, Maurizio Mencuccini, John Grace & Patrick Meir
Litterfall dynamics in tropical forests are a good indicator of overall tropical forest function, indicative of carbon invested in both photosynthesising tissues and reproductive organs such as flowers and fruits. These dynamics are sensitive to changes in climate, such as drought, but little is known about the long-term responses of tropical forest litterfall dynamics to extended drought stress. We present a 15-year dataset of litterfall (leaf, flower and fruit, and twigs) from the world's only...

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: 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: 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: 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: 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: 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: 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: 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...
