Data from: High species richness and lineage diversity of reef corals in the mesophotic zone

Paul R. Muir, Carden C. Wallace, Michel Pichon & Pim Bongaerts
Coral reefs are increasingly threatened by thermal bleaching and tropical storm events associated with rising sea surface temperatures. Deeper habitats offer some protection from these impacts and may safeguard reef-coral biodiversity, but their faunas are largely undescribed for the Indo-Pacific. Here, we show high species richness of scleractinian corals in mesophotic habitats (30-125 m) for the northern Great Barrier Reef region that greatly exceeds previous records for mesophotic habitats globally. Overall, 45% of shallow reef...

Data from: An Ishihara-style test of animal colour vision

Karen L. Cheney, Naomi.F. Green, Alexander P. Vibert, Misha Vorobyev, Justin Marshall, Daniel C. Osorio & John A. Endler
Colour vision mediates ecologically relevant tasks for many animals, such as mate choice, foraging and predator avoidance. However, our understanding of animal colour perception is largely derived from human psychophysics, even though animal visual systems differ from our own. Behavioural tests of non-human animals are required to understand how colour signals are perceived by them. Here we introduce a novel test of colour vision in animals inspired by the Ishihara colour charts, which are widely...

Data from: Warming impacts on early life stages increase the vulnerability and delay the population recovery of a long-lived habitat-forming macroalga

Pol Capdevila, Bernat Hereu, Roberto Salguero-Gómez, Graciel·La Rovira, Alba Medrano, Emma Cebrian, Joaquim Garrabou, Diego K. Kersting & Cristina Linares
1. Understanding the combined effects of global and local stressors is crucial for conservation and management, yet challenging due to the different scales at which these stressors operate. Here we examine the effects of one of the most pervasive threats to marine biodiversity, ocean warming, on the early life stages of the habitat-forming macroalga Cystoseira zosteroides, its long-term consequences for population resilience and its combined effect with physical stressors. 2. First, we performed a controlled...

Data from: New small-bodied ornithopods (Dinosauria, Neornithischia) from the Early Cretaceous Wonthaggi Formation (Strzelecki Group) of the Australian-Antarctic rift system, with revision of Qantassaurus intrepidus Rich and Vickers-Rich, 1999

Matthew C. Herne, Jay P. Nair, Alistair R. Evans & Alan M. Tait
The Flat Rocks locality in the Wonthaggi Formation (Strzelecki Group) of the Gippsland Basin, southeastern Australia, hosts fossils of a late Barremian vertebrate fauna that inhabited the ancient rift between Australia and Antarctica. Known from its dentary, Qantassaurus intrepidus Rich and Vickers-Rich, 1999 has been the only dinosaur named from this locality. However, the plethora of vertebrate fossils collected from Flat Rocks suggests that further dinosaurs await discovery. From this locality, we name a new...

Data from: Adaptation to reef habitats through selection on the coral animal and its associated microbiome

Madeleine J.H. Van Oppen, Pim Bongaerts, Pedro Frade, Lesa M. Peplow, Sarah E. Boyd, Hieu T. Nim, Line K. Bay & Madeleine J. H. Van Oppen
Spatially adjacent habitats on coral reefs can represent highly distinct environments, often harbouring different coral communities. Yet, certain coral species thrive across divergent environments. It is unknown whether the forces of selection are sufficiently strong to overcome the counteracting effects of the typically high gene flow over short distances, and for local adaptation to occur. We screened the coral genome (using restriction-site-associated sequencing [RAD-seq]), and characterized both the dinoflagellate photosymbiont and tissue-associated prokaryote microbiomes (using...

Data from: Regional climate and local-scale biotic acceptance explain native-exotic diversity relationships in Australian annual plant communities

Isaac R. Towers, John M. Dwyer, John. M. Dwyer & Isaac. R. Towers
Native and exotic species richness is expected to be negatively related at small spatial scales where individuals interact, and positive at larger spatial scales as a greater variety of habitats are sampled. However, a range of native-exotic richness relationships (NERRs) have been reported, including positive at small scales and negative at larger scales. We present a hierarchical metacommunity framework to explain how contrasting NERRs may emerge across scales and study systems, and then apply this...

Data from: Taphonomy of Isisfordia duncani specimens from the Lower Cretaceous (upper Albian) portion of the Winton Formation, Isisford, central-west Queensland

Caitlin E. Syme & Steven W. Salisbury
Taphonomic analysis of fossil material can benefit from including the results of actualistic decay experiments. This is crucial in determining the autochthony or allochthony of fossils of juvenile and adult Isisfordia duncani, a basal eusuchian from the Lower Cretaceous (upper Albian) distal-fluvial-deltaic lower Winton Formation near Isisford. The taphonomic characteristics of the I. duncani fossils were documented using a combination of traditional taphonomic analysis alongside already published actualistic decay data from juvenile Crocodylus porosus carcasses....

Data from: Pattern edges improve predator learning of aposematic signals

Naomi F. Green, Holly H. Urquhart, Cedric P. Van Den Berg, N. Justin Marshall & Karen L. Cheney
Edges are salient visual cues created by abrupt changes in luminance and color, and are crucial in perceptual tasks such as motion detection and object recognition. Disruptively colored animals exploit edge detection mechanisms to obscure their body outline and/or to conceal themselves against their background. Conversely, aposematic species may use contrasting patterns with well-defined edges to create highly salient, memorable warning signals. In this study, we investigated how the amount of internal pattern edge, colored...

Data from: Assessment of plasma proteomics biomarker’s ability to distinguish benign from malignant lung nodules

Gerard A. Silvestri, Nichole T. Tanner, Paul Kearney, Anil Vachani, Pierre P. Massion, Alexander Porter, Steven C. Springmeyer, Kenneth C. Fang, David Midthun, Peter J. Mazzone, D. Madtes, J. Landis, A. Levesque, K. Rothe, M. Balaan, B. Dimitt, B. Fortin, N. Ettinger, A. Pierre, L. Yarmus, K. Oakjones-Burgess, N. Desai, Z. Hammoud, A. Sorenson, R. Murali … & F. Allison
Background: Lung nodules are a diagnostic challenge, with an estimated yearly incidence of 1.6 million in the United States. This study evaluated the accuracy of an integrated proteomic classifier in identifying benign nodules in patients with a pretest probability of cancer (pCA) ≤ 50%. Methods: A prospective, multicenter observational trial of 685 patients with 8- to 30-mm lung nodules was conducted. Multiple reaction monitoring mass spectrometry was used to measure the relative abundance of two...

Data from: Accurate predictions of coexistence in natural systems require the inclusion of facilitative interactions and environmental dependency

Malyon D. Bimler, Daniel B. Stouffer, Hao Ran Lai & Margaret M. Mayfield
1. Coexistence between plant species is well known to depend on the outcomes of species interactions within an environmental context. The incorporation of environmental variation into empirical studies of coexistence are rare, however, due to the complex experiments needed to do so and the lack of feasible modelling approaches for determining how environmental factors alter specific coexistence mechanisms. 2. In this paper, we present a simple modelling framework for assessing how variation in species interactions...

Data from: Using virtual reality to estimate aesthetic values of coral reefs

Julie Vercelloni, Sam Clifford, M. Julian Caley, Alan R. Pearse, Ross Brown, Allan James, Bryce Christensen, Tomasz Bednarz, Ken Anthony, Manuel González-Rivero, Kerrie Mengersen & Erin E. Peterson
Aesthetic value, or beauty, is important to the relationship between humans and natural environments and is, therefore, a fundamental socioeconomic attribute of conservation alongside other ecosystem services. However, beauty is difficult to quantify and is not estimated well using traditional approaches to monitoring coral reef aesthetics. To improve the estimation of ecosystem aesthetic values, we developed and implemented a novel framework used to quantify features of coral reef aesthetics based on people’s perceptions of beauty....

Data from: Multidimensional analyses of physical performance reveal a size dependent trade-off between suites of traits

Jordan E. Charters, Jaime Heiniger, Christofer J. Clemente, Skye F. Cameron, Ami F. Amir Abdul Nasir, Amanda C. Niehaus & Robbie S. Wilson
1. Animal movement is multidimensional and complex, and to understand the motor system of wild animals in the context of their natural ecology, we must analyze how suites of performance traits both mutualistically and antagonistically affect function —a necessity highlighted by previous work on performance trade-offs. 2. Evidence from some studies of human athletes using multidimensional analyses of performance suggests that overall quality among individuals can mask functional trade-offs within them, yet no studies have...

Data from: Cyclic population dynamics and density-dependent intransitivity as pathways to coexistence between co-occurring annual plants

Daniel B. Stouffer, Claire E. Wainwright, Thomas Flanagan & Margaret M. Mayfield
1. Recent studies have brought renewed attention to the importance of complex species interactions - notably intransitive interactions - to patterns of plant community diversity. One underappreciated avenue through which intransitivity can occur is through cyclic population dynamics. Though such cyclic intransitive relationships have been extensively studied in predator-prey systems, evidence of their importance in competitive communities, notably plant communities, is more limited. Most studies of coexistence in plant communities assume fixed-point coexistence even while...

Data from: Environmentally induced development costs underlie fitness tradeoffs

Gregory M. Walter, Melanie J. Wilkinson, J. David Aguirre, Mark W. Blows, Daniel Ortiz-Barrientos & Greg M. Walter
Local adaptation can lead to genotype‐by‐environment interactions, which can create fitness tradeoffs in alternative environments, and govern the distribution of biodiversity across geographic landscapes. Exploring the ecological circumstances that promote the evolution of fitness tradeoffs requires identifying how natural selection operates and during which ontogenetic stages natural selection is strongest. When organisms disperse to areas outside their natural range, tradeoffs might emerge when organisms struggle to reach key life history stages, or alternatively, die shortly...

Data from: Groundwater enhances aboveground growth in mangroves

Matthew A. Hayes, Amber Jesse, Nina Welti, Basam Tabet, David Lockington & Catherine E. Lovelock
1. Groundwater flow through coastal wetlands plays an important role in the maintenance of productivity of intertidal ecosystems. Groundwater can reduce salinity and increase nutrient availability which can enhance plant growth and alter plant biomass allocation patterns. 2. Here, we used stable isotopes of oxygen and hydrogen to assess how groundwater influences belowground and aboveground growth in the widespread mangrove species Avicennia marina. 3. We found source water within tree stems varied seasonally, with non-saline...

Data from: Without management interventions, endemic wet-sclerophyll forest is transitioning to rainforest in World Heritage listed K’gari (Fraser Island), Australia

Vithya Krishnan, Nicole Robinson, Jennifer Firn, Grahame Applegate, John Herbohn & Susanne Schmidt
Wet-sclerophyll forests are unique ecosystems that can transition to dry-sclerophyll forests or to rainforests. Understanding of the dynamics of these forests for conservation is limited. We evaluated the long-term succession of wet-sclerophyll forest on World Heritage listed K’gari (Fraser Island)the world’s largest sand island. We recorded the presence and growth of tree species in three 0.4 hectare plots that had been subjected to selective logging, fire, and cyclone disturbance over 65 years, from 1952 to...

Data from: Geometric models to explore mechanisms of dynamic shape change in skeletal muscle

Taylor J.M. Dick, James M. Wakeling & Taylor J. M. Dick
Skeletal muscle bulges when it contracts. These 3-dimensional (3D) dynamic shape changes play an important role in muscle performance by altering the range of fascicle velocities over which a muscle operates. However traditional muscle models are 1D and cannot fully explain in vivo shape changes. In this study we compared medial gastrocnemius behaviour during human cycling (fascicle length changes and rotations) predicted by a traditional 1D Hill-type model and by models that incorporate 2D and...

Data from: Seascapes as drivers of herbivore assemblages in coral reef ecosystems

George Roff, Sonia Bejarano, Mark Priest, Alyssa Marshell, Iliana Chollett, Robert S. Steneck, Christopher Doropoulos, Yimnang Golbuu & Peter J. Mumby
Herbivorous fish maintain a critical ecosystem function on coral reefs by grazing algae and maintaining highly productive algal turf assemblages. Current paradigms implicate habitat complexity, predation and primary productivity as major drivers of the distribution and abundance of herbivorous fish, yet little is known about the relative contribution of these factors. Here, we compare bottom-up and top-down drivers of notional herbivore assemblages across an environmental gradient of wave exposure in the Palau archipelago. We surveyed...

Data from: The influence of distance to perennial surface water on ant communities in Mopane woodlands, northern Botswana

Fredrik Dalerum, Tarryn Anne Retief, Carl Peter Havemann, Christian T. Chimimba, Benrdt Janse Van Rensburg & Berndt Janse Van Rensburg
Studies of biodiversity along environmental gradients provide information on how ecological communities change in response to biotic and abiotic factors. For instance, distance to water is associated with several factors that shape the structure and the functioning of ecosystems at a range of spatial scales. We investigated the influence of distance to a perennial water source on ant communities in a semi-arid savanna in northern Botswana. Ant abundance, taxonomic richness and both alpha and beta...

Data from: Do slower movers have lower reproductive success and higher mutation load?

Carly B. Walsh & Katrina McGuigan
Deleterious mutations occur frequently in eukaryotes, resulting in individuals carrying multiple alleles that decrease their fitness. At a population level, if unchecked, accumulation of this mutation load can ultimately lead to extinction. How selection counters the accumulation of mutation load, limiting declines in population fitness, is not well understood. Here, we use manipulative experiments in zebrafish (Danio rerio) to investigate the opportunities for selection on mutation load. Inducing high mutation load through mutagenesis, we applied...

Data from: Avoided emissions and conservation of scrub mangroves: a potential Blue Carbon project in the Gulf of California, Mexico

M. Fernanda Adame, Eduardo Najera, Catherine E. Lovelock & Chris J. Brown
Mangroves are considered ideal ecosystems for Blue Carbon projects. However, because of their short stature, some mangroves (“scrub” mangroves, < 2m) do not fulfil the current definition of “forests” which makes them ineligible for emission reduction programs such as REDD+. Short stature mangroves can be the dominant form of mangroves in arid and poor nutrient landscapes, and emissions from their deforestation and degradation could be substantial. Here, we describe a potential Blue Carbon project in...

Data from: Prediction error and repetition suppression have distinct effects on neural representations of visual information

Matthew F. Tang, Cooper A. Smout, Ehsan Arabzadeh & Jason B. Mattingley
Predictive coding theories argue that recent experience establishes expectations in the brain that generate prediction errors when violated. Prediction errors provide a possible explanation for repetition suppression, where evoked neural activity is attenuated across repeated presentations of the same stimulus. The predictive coding account argues repetition suppression arises because repeated stimuli are expected, whereas non-repeated stimuli are unexpected and thus elicit larger neural responses. Here we employed electroencephalography in humans to test the predictive coding...

Data from: Landscape-specific thresholds in the relationship between species richness and natural land cover

Jeremy S. Simmonds, Berndt J. Van Rensburg, Ayesha I. T. Tulloch & Martine Maron
1. Thresholds in the relationship between species richness and natural land cover can inform landscape-level vegetation protection and restoration targets. However, landscapes differ considerably in composition and other environmental attributes. If the effect of natural land cover on species richness depends on (i.e. interacts with) these attributes, and this affects the value of thresholds in this relationship, such dependencies must be considered when using thresholds to guide landscape management. 2. We hypothesised that the amount...

Data from: Cultural revolutions reduce complexity in the songs of humpback whales

Jenny A. Allen, Ellen C. Garland, Rebecca A. Dunlop & Michael J. Noad
Much evidence for non-human culture comes from vocally learned displays, such as the vocal dialects and song displays of birds and cetaceans. While many oscine birds use song complexity to assess male fitness, the role of complexity in humpback whale (Megaptera novaeangliae) song is uncertain due to population-wide conformity to one song pattern. Although songs change gradually each year, the eastern Australian population also completely replaces their song every few years in cultural ‘revolutions’. Revolutions...
