Marcus, John C. Morris, Katrina Paumier, Chengjie Xiong, Ricardo Allegri, Sarah B. Berman, William Klunk, James Nobel, John Ringman, Bernardino Ghetti, Martin Farlow, Reisa Anne Sperling, Jasmeer Chhatwal, Stephen Salloway, Neil R. Graff-Radford … & Randall J. Bateman
Objective: To assess the onset, sequence and rate of progression of comprehensive biomarker and clinical measures across the spectrum of Alzheimer disease using the Dominantly Inherited Alzheimer Network (DIAN) study and compare these to cross-sectional estimates. Methods: We conducted longitudinal clinical, cognitive, cerebrospinal fluid (CSF) and neuroimaging assessments (mean of 2.7 (+/- 1.1) visits) in 217 DIAN participants. Linear mixed effects models were used to assess changes in each measure relative to individuals’ estimated years...

Data from: Fern and lycophyte diversity in the Pacific Northwest: patterns and predictors

Melanie A. Link-Perez & Shawn W. Laffan
Recent floristic efforts in the Pacific Northwest (PNW) have made it possible to characterize the broad-scale patterns of fern and lycophyte diversity across this geologically-complex region of western North America. The physiography of the PNW has been developing for over 200 million years, but Pleistocene glaciation-induced migrations and recolonizations have strongly influenced the assembly of the flora. With the high dispersal potential of spores, distribution patterns of pteridophytes may represent habitat suitability more than dispersal...

Data from: Below-ground processes control the success of an invasive seaweed

Paul E. Gribben, Torsten Thomas, Antonio Pusceddu, Lisa Bonechi, Silvia Bianchelli, Emanuela Buschi, Shaun Nielsen, Chiara Ravaglioli & Fabio Bulleri
1. Whilst the successful establishment and spread of invasive species can be determined by above ground processes, results are often equivocal. Emergent research, mostly from terrestrial ecosystems, demonstrates that below-ground processes (nutrient cycling, chemical properties) under microbial control can mediate interactions between native and invasive plants. Because microbes can control similar sediment properties in marine ecosystem that influence plant fitness, we argue that below-ground properties should also exert strong control interactions between native and invasive...

Data from: Isolation by environment in the highly mobile olive ridley turtle (Lepidochelys olivacea) in the eastern Pacific

Clara J. Rodriguez-Zarate, Jonathan Sandoval-Castillo, Erik Van Sebille, Robert G. Keane, Axayácatl Rocha-Olivares, José Urteaga & Luciano B. Beheregaray
Spatial and temporal scales at which processes modulate genetic diversity over the landscape are usually overlooked, impacting the design of conservation management practices for widely distributed species. We examine processes shaping population divergence in highly mobile species by re-assessing the case of panmixia in the iconic olive ridley turtle from the eastern Pacific. We implemented a biophysical model of connectivity and a seascape genetic analysis based on nuclear DNA variation of 634 samples collected from...

Data from: NIHSS cut-point for predicting outcome in supra- vs infra-tentorial acute ischemic stroke

Sohei Yoshimura, Richard I. Lindley, Cheryl Carcel, Shoichiro Sato, Candice Delcourt, Xia Wang, John Chalmers & Craig S. Anderson
Objective: To determine the optimal cut-point on the National Institutes of Health Stroke Scale (NIHSS) for predicting poor 90-day clinical outcome in patients with supra- and infra-tentorial acute ischemic stroke (AIS). Methods: Data are from participants of the alteplase-dose arm of the randomised controlled trial, Enhanced Control of Hypertension and Thrombolysis Stroke Study (ENCHANTED). Associations between baseline characteristics of clinically-defined supratentorial and infratentorial AIS patients and poor functional outcome, defined by scores 3-6 on the...

Data from: Two sources of bias explain errors in facial age estimation

Colin W.G. Clifford, Tamara Watson, David White & Tamara L. Watson
Accurate age estimates underpin our everyday social interactions, the provision of age-restricted services and police investigations. Previous work suggests that these judgments are error-prone, but the processes giving rise to these errors are not understood. Here we present the first systematic test of bias in age estimation using a large database of standardized passport images of heterogeneous ages (n = 3948). In three experiments we tested a range of perceiver age groups (n = 84),...

Data from: Computer simulations show that Neanderthal facial morphology represents adaptation to cold and high energy demands, but not heavy biting

Stephen Wroe, William C.H. Parr, Justin A. Ledogar, Jason Bourke, Samuel P. Evans, Luca Fiorenza, Stefano Benazzi, Jean-Jacques Hublin, Chris Stringer, Ottmar Kullmer, Michael Curry, Todd C. Rae, Todd R. Yokley & William C. H. Parr
Three adaptive hypotheses have been forwarded to explain the distinctive Neanderthal face: 1) an improved ability to accommodate high anterior bite forces, 2) more effective conditioning of cold and/or dry air, and, 3) adaptation to facilitate greater ventilatory demands. We test these hypotheses using three-dimensional models of Neanderthals, modern humans, and a close outgroup (H. heidelbergensis), applying finite element analysis (FEA) and computational fluid dynamics (CFD). This is the most comprehensive application of either approach...

Data from: Perceived threats of infanticide reduce maternal allocation during lactation and lead to elevated oxidative damage in offspring

Teagan Gale, Michael Garratt & Robert C. Brooks
Maternal investment is costly to the mother but essential to offspring survival in altrical species. Infanticide by novel males results in loss of maternal investment, and maternal strategies have evolved to mitigate these losses. One such maternal strategy, the Bruce effect, involves spontaneous abortion by females of some mammal species when exposed to a novel male during pregnancy. In mice, the Bruce effect only occurs during early pregnancy, but we have previously found that female...

Data from: Rare long-distance dispersal of a marine angiosperm across the Pacific Ocean

Timothy M. Smith, Paul H. York, Bernardo R. Broitman, Martin Thiel, Graeme C. Hays, Erik Van Sebille, Nathan F. Putman, Peter I. Macreadie & Craig D. H. Sherman
Aim: Long-distance dispersal (LDD) events occur rarely but play a fundamental role in shaping species biogeography. Lying at the heart of island biogeography theory, LDD relies on unusual events to facilitate colonisation of new habitats and range expansion. Despite the importance of LDD, it is inherently difficult to quantify due to the rarity of such events. We estimate the probability of LDD of the seagrass Heterozostera nigricaulis, a common Australian species, across the Pacific Ocean...

Data from: Reversing functional extinction of mammals prompts a rethink of paradigms about seed fate in arid Australia

Charlotte Mills, Mike Letnic & Charlotte H. Mills
Functional extinction of once abundant species has frequently preceded understanding of their ecological roles. Consequently, our understanding of ecosystems is prone to shifting baselines because it often relies on observations made on depauperate species assemblages. In Australian deserts, current paradigms are that ants are the dominant granivores, mammals are unimportant seed predators and that myrmecochory in many Australian shrubs is an adaptation to increase dispersal distance and direct seeds to favourable germination sites. Here, we...

Data from: Primary productivity is related to niche width in the Australian Wet Tropics

Hugh M. Burley, Karel Mokany, Shawn W. Laffan, Kristen J. Williams, Dan Metcalfe, Helen T. Murphy, Andrew Ford, Tom D. Harwood & Simon Ferrier
Aim: A key ecological debate is whether ecosystem functions are distinctly influenced by biological diversity across broad scales. Although recent work has emphasized the importance of links between ecosystem functions and measures of ecological specialization as proxies of biodiversity, few studies have analysed macroecological relationships empirically in diverse environments. We tested whether gross primary productivity (GPP) in the Australian Wet Tropics (WT) was distinctly related to community‐level measures of the ecological specialization of component tree...

Data from: Multiple biological mechanisms result in correlations between pre- and post-mating traits that differ among versus within individuals and genotypes

Cristina Tuni, Chang S. Han & Niels J. Dingemanse
Reproductive traits involved in mate acquisition (pre-mating traits) are predicted to covary with those involved in fertilization success (post-mating traits). Variation in male quality may give rise to positive, and resource allocation trade-offs to negative, covariances between pre- and post-mating traits. Empirical studies have yielded mixed results. Progress is hampered as researchers often fail to appreciate that mentioned biological mechanisms can act simultaneously but at different hierarchical levels of biological variation: genetic correlations may, for...

Data from: Latitudinal variation in seagrass herbivory: global patterns and explanatory mechanisms

Adriana Vergés, Christopher Doropoulos, Rob Czarnik, Kathryn McMahon, Nil Llonch & Alistair G. B. Poore
Aim: The aim was to quantify latitudinal patterns in seagrass–herbivore interactions in the context of a warming climate. Location: We carried out a global meta‐analysis combined with a field experiment across 1,700 km and 12° of latitude in Western Australia. Time period: 1984–2014. Major taxa studied: Seagrasses. Methods: We first synthesized the global literature on herbivore exclusion experiments in seagrasses to test whether differences in herbivore impacts are related to latitude and sea surface temperature....

Data from: Recent grazing reduces reptile richness but historic grazing filters reptiles based on their functional traits

James Val, Samantha K. Travers, Ian Oliver, Terry B. Koen & David J. Eldridge
1. Grazing by mammalian herbivores can alter vegetation structure and composition. It can therefore affect critical habitat features used by native wildlife for shelter, feeding and breeding. This can have variable effects, which advantage or disadvantage particular species, depending on habitat requirements. 2. We tested the relative effects of recent and historic livestock grazing and recent rabbit and kangaroo grazing on all reptiles, and on specific groups of reptiles based on three functional traits: habitat...

Data from: The role of red coloration and song in peacock spiders: insights into complex signaling systems

Madeline B. Girard, Michael M. Kasumovic & Damian O. Elias
Research on animal signaling enhances our understanding of links between sensory processing, decision-making, behavior, and evolution. Studies of sexually-selected signals may be particularly informative as mate choice provides access to decision patterns in the way that courtship leads to an easily observable behavioral output in choosers, i.e. mating. Male peacock spiders have some of the most elaborate and varied courtship displays known among animals. Particularly striking to human observers is the diversity of red, orange...

Data from: Maternal presence facilitates plasticity in offspring behavior: insights into the evolution of parental care

Kirke L. Munch, Daniel W.A. Noble, Luke Budd, Aryana Row, Erik Wapstra, Geoffrey M. While & Daniel W A Noble
Fundamental to the definition of parental care is that care confers benefits to the offspring. However, the mechanisms resulting in these benefits remain poorly understood, particularly in species where postnatal care is not obligatory. Here, we address this shortcoming using a lizard, Liopholis whitii, in which family life is facultative and relatively simple – extending to prolonged associations between parents and offspring within the parental territory. Using a split-clutch design, we housed offspring either with...

Data from: Elucidating biogeographical patterns in Australian native canids using genome wide SNPs

Kylie M. Cairns, Laura M. Shannon, Janice Koler-Matznick, J. William O. Ballard & Adam R. Boyko
Dingoes play a strong role in Australia’s ecological framework as the apex predator but are under threat from hybridization and agricultural control programs. Government legislation lists the conservation of the dingo as an important aim, yet little is known about the biogeography of this enigmatic canine, making conservation difficult. Mitochondrial and Y chromosome DNA studies show evidence of population structure within the dingo. Here, we present the data from Illumina HD canine chip genotyping for...

Data from: Host diet mediates a negative relationship between abundance and diversity of Drosophila gut microbiota

Berra Erkosar, Erika Yashiro, Felix Zajitschek, Urban Friberg, Alexei A. Maklakov, Jan Roelof Van Der Meer & Tadeusz J. Kawecki
Nutrient supply to ecosystems has major effects on ecological diversity, but it is unclear to what degree the shape of this relationship is general versus dependent on the specific environment or community. Although the diet composition in terms of the source or proportions of different nutrient types is known to affect gut microbiota composition, the relationship between the quantity of nutrients supplied and the abundance and diversity of the intestinal microbial community remains to be...

Data from: Web building and silk properties functionally covary among species of wolf spider

Mariángeles Lacava, Arley Camargo, Luiz F. Garcia, Martin Santana, Jian Fang, Xungai Wang & Sean J. Blamires
While phylogenetic studies have shown covariation between the properties of spider major ampullate (MA) silk and web building, both spider webs and silks are highly plastic so we cannot be sure whether these traits functionally co-vary or just vary across environments that the spiders occupy. Since MaSp2-like proteins provide MA silk with greater extensibility, their presence is considered necessary for spider webs to effectively capture prey. Wolf spiders (Lycosidae) are predominantly non-web building, but a...

Data from: Apex predator suppression is linked to restructuring of ecosystems via multiple ecological pathways

Viyanna Leo, Richard P. Reading, Christopher Gordon & Mike Letnic
Removal of apex predators can drive ecological regime shifts owing to compensatory positive and negative population level responses by organisms at lower trophic levels. Despite evidence that apex predators can influence ecosystems though multiple ecological pathways, most studies investigating apex predators’ effects on ecosystems have considered just one pathway in isolation. Here, we provide evidence that lethal control of an apex predator, the dingo (Canis dingo), drives shifts in the structure of Australia’s tropical-savannah ecosystems....

Data from: Palaeoecological inferences for the fossil Australian snakes Yurlunggur and Wonambi (Serpentes, Madtsoiidae)

Alessandro Palci, Mark N. Hutchinson, Michael W. Caldwell, John D. Scanlon, Michael S.Y. Lee & Michael S. Y. Lee
Madtsoiids are among the most basal snakes, with a fossil record dating back to the Upper Cretaceous (Cenomanian). Most representatives went extinct by the end of the Eocene, but some survived in Australia until the late Cenozoic. Yurlunggur and Wonambi are two of these late forms, and also the best-known madtsoiids to date. A better understanding of the anatomy and palaeoecology of these taxa may shed light on the evolution and extinction of this poorly...

Data from: Identification of allosteric disulphides from labile bonds in X-ray structures

Aster E. Pijning, Joyce Chiu, Reichelle X. Yeo, Jason W. H. Wong & Philip J. Hogg
Protein disulfide bonds link pairs of cysteine sulfur atoms and are either structural or functional motifs. The allosteric disulfides control the function of the protein in which they reside when cleaved or formed. Here, we identify potential allosteric disulfides in all Protein Data Bank X-ray structures from bonds that are present in some molecules of a protein crystal but absent in others, or present in some structures of a protein but absent in others. We...
