Skull shape of a widely-distributed, endangered marsupial reveals little evidence of local adaptation between fragmented populations

Pietro Viacava, Vera Weisbecker, Simone P. Blomberg, Gabriele Sansalone, Thomas Guillerme, Skye F. Cameron, Robbie S. Wilson & Matthew J. Phillips
The biogeographical distribution of diversity among populations of threatened mammalian species is generally investigated using population genetics. However, intraspecific phenotypic diversity is rarely assessed beyond taxonomy-focused linear measurements or qualitative descriptions. Here, we use a technique widely used in the evolutionary sciences – geometric morphometrics – to characterize shape diversity in the skull of an endangered marsupial, the northern quoll, across its 5,000 km distribution range along Northern Australia. Skull shape is a proxy for...

ISIMIP3b ocean input data

Matthias Büchner
The Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) provides a framework for the collation of a consistent set of climate impact data across sectors and scales. It also provides a unique opportunity for considering interactions between climate change impacts across sectors through consistent scenarios.
The ISIMIP3b part of the third simulation round is dedicated to a quantification of climate-related risks at different levels of global warming and socio-economic change. ISIMIP3b group I simulations are based on historical...

Data from: Giant coral reef fishes display markedly different susceptibility to night spearfishing

Alan R. Pearse, Richard J. Hamilton, John Howard Choat, John Pita, Glenn Almany, Nate Peterson, Grant S. Hamilton & Erin E. Peterson
The humphead wrasse (Cheilinus undulatus) and bumphead parrotfish (Bolbometopon muricatum) are two of the largest, most iconic fishes of Indo-Pacific coral reefs. Both species form prized components of subsistence and commercial fisheries and are vulnerable to overfishing. C. undulatus is listed as Endangered and B. muricatum as Vulnerable on the IUCN Red List of Threatened Species. We investigated how night spearfishing pressure and habitat associations affected both species in a relatively lightly exploited setting; the...

Data from: Spatial heterogeneity in species composition constrains plant community responses to herbivory and fertilization

Dorothee Hodapp, Elizabeth T. Borer, W. Stanley Harpole, Eric M. Lind, Eric W. Seabloom, Peter B. Adler, Juan Alberti, Carlos A. Arnillas, Jonathan D. Bakker, Lori Biederman, Marc Cadotte, Elsa E. Cleland, Scott Collins, Philip A. Fay, Jennifer Firn, Nicole Hagenah, Yann Hautier, Oscar Iribarne, Johannes M.H. Knops, Rebecca L. McCulley, Andrew MacDougall, Joslin L. Moore, John W. Morgan, Brent Mortensen, Kimberly J. La Pierre … & Johannes M. H. Knops
Environmental change can result in substantial shifts in community composition. The associated immigration and extinction events are likely constrained by the spatial distribution of species. Still, studies on environmental change typically quantify biotic responses at single spatial (time series within a single plot) or temporal (spatial beta-diversity at single time points) scales, ignoring their potential interdependence. Here, we use data from a global network of grassland experiments to determine how turnover responses to two major...

Data from: Mobile phones as monitors of personal exposure to air pollution: is this the future?

Mawutorli Nyarku, Mandana Mazaheri, Rohan Jayaratne, Matthew Dunbabin, Mahmudur M. Rahman, Erik Uhde & Lidia Morawska
Mobile phones have a large spectrum of applications, aiding in risk prevention and improving health and wellbeing of their owners. So far, however, they have not been used for direct assessment of personal exposure to air pollution. In this study, we comprehensively evaluated the first, and the only available, mobile phone - BROAD Life - equipped with air pollution sensors (PM2.5 and VOC), to answer the question whether this technology is a viable option in...

Data from: Priorities and motivations of marine coastal restoration research

Elisa Bayraktarov, Shantala Brisbane, Phoebe J Stewart-Sinclair, Audrey Van Herwaarden, Keila Stark, Valerie Hagger, Carter S Smith, Kerrie A Wilson, Catherine E Lovelock, Chris Gillies, Andrew D L Steven & Megan I Saunders
Active restoration is becoming an increasingly important conservation intervention to counteract the degradation of marine coastal ecosystems. Understanding what has motivated the scientific community to research the restoration of marine coastal ecosystems and how restoration research projects are funded is essential if we want to scale-up restoration interventions to meaningful extents.Here, we systematically review and synthesize data to understand the motivations for research on the restoration of coral reefs, seagrass, mangroves, saltmarsh, and oyster reefs....

Developmental Cost Theory predicts thermal environment and vulnerability to global warming

Dustin Marshall, Amanda Pettersen, Michael Bode & Craig White
Metazoans must develop from zygotes to feeding organisms. In doing so, developing offspring consume up to 60% of the energy provided by their parent. The cost of development depends on two rates: metabolic rate, which determines the rate that energy is used; and developmental rate, which determines the length of the developmental period. Both development and metabolism are highly temperature-dependent such that developmental costs should be sensitive to the local thermal environment. Here we develop,...

Data from: Managing seagrass resilience under cumulative dredging affecting light: predicting risk using dynamic Bayesian networks

Paul Pao-Yen Wu, Kathryn McMahon, Michael A. Rasheed, Gary A. Kendrick, Paul H. York, Kathryn Chartrand, M. Julian Caley & Kerrie Mengersen
Coastal development is contributing to ongoing declines of ecosystems globally. Consequently, understanding the risks posed to these systems, and how they respond to successive disturbances, is paramount for their improved management. We study the cumulative impacts of maintenance dredging on seagrass ecosystems as a canonical example. Maintenance dredging causes disturbances lasting weeks to months, often repeated at yearly intervals. We present a risk-based modelling framework for time varying complex systems centred around a dynamic Bayesian...

Data from: Genomic evidence for the parallel evolution of coastal forms in the Senecio lautus complex

Federico Roda, Luke Ambrose, Gregory M. Walter, Huanle L. Liu, Andrea Schaul, Andrew Lowe, Pieter B. Pelser, Peter Prentis, Loren H. Rieseberg & Daniel Ortiz-Barrientos
Instances of parallel ecotypic divergence where adaptation to similar conditions repeatedly cause similar phenotypic changes in closely related organisms are useful for studying the role of ecological selection in speciation. Here we used a combination of traditional and next generation genotyping techniques to test for the parallel divergence of plants from the Senecio lautus complex, a phenotypically variable groundsel that has adapted to disparate environments in the South Pacific. Phylogenetic analysis of a broad selection...

Data from: Passive acoustics and sound recognition provide new insights on status and resilience of an iconic endangered marsupial (koala Phascolarctos cinereus) to timber harvesting

Bradley S. Law, Traecey Brassil, Leroy Gonsalves, Paul Roe, Anthony Truskinger & Anna McConville
Retention forestry aims to mitigate impacts of native forestry on biodiversity, but data are limited on its effectiveness for threatened species. We used acoustics to investigate the resilience of a folivorous marsupial, the koala Phascolarctos cinereus, to timber harvesting where a key mitigation practice is landscape exclusion of harvesting. We deployed acoustic recorders at 171 sites to record male bellows (~14,640 hours) for use in occupancy modelling and for comparisons of bellow rate (bellows night-1)....

Data from: Herbivory and eutrophication mediate grassland plant nutrient responses across a global climatic gradient

T. Michael Anderson, Daniel M. Griffith, James B. Grace, Eric M. Lind, Peter B. Adler, Lori A. Biederman, Dana M. Blumenthal, Pedro Daleo, Jennifer Firn, Nicole Hagenah, W. Stanley Harpole, Andrew S. MacDougall, Rebecca L. McCulley, Suzanne M. Prober, Anita C. Risch, Mahesh Sankaran, Martin Schütz, Eric W. Seabloom, Carly J. Stevens, Lauren L. Sullivan, Peter D. Wragg & Elizabeth T. Borer
Plant stoichiometry, the relative concentration of elements, is a key regulator of ecosystem functioning and is also being altered by human activities. In this paper we sought to understand the global drivers of plant stoichiometry and compare the relative contribution of climatic vs. anthropogenic effects. We addressed this goal by measuring plant elemental (C, N, P and K) responses to eutrophication and vertebrate herbivore exclusion at eighteen sites on six continents. Across sites, climate and...

Data from: Reconstructing the evolution of giant extinct kangaroos: comparing the utility of DNA, morphology, and total evidence

Manuela Cascini, Kieren J. Mitchell, Alan Cooper & Matthew J. Phillips
Combined “total evidence” analysis of molecular and morphological data offers the opportunity to objectively merge fossils into the tree of life, and challenges the primacy of solely DNA based phylogenetic and dating inference, even among modern taxa. To investigate the relative utility of DNA, morphology, and total evidence for evolutionary inference, we sequenced the first near-complete mitochondrial genomes from extinct Australian megafauna: a 40-50 thousand year old giant short-faced kangaroo (Simosthenurus occidentalis) and giant wallaby...

Data from: Mammalian herbivores affect leafhoppers associated with specific plant functional types at different timescales

Martijn L. Vandegehuchte, Valeria Trivellone, Martin Schütz, Jennifer Firn, Frederic De Schaetzen & Anita C. Risch
1. Theory predicts that mammalian herbivores affect the quantity and quality of plants on which they preferentially feed in the short term. In the longer term, they can promote either preferred or less preferred plants, depending on whether preferred plants are adapted or sensitive to grazing. Less clear are the short- and long-term responses of herbivorous insects to mammalian herbivory, and how these responses depend on the specific plants or plant functional types on which...

Data from: Evolutionary potential of the extrinsic incubation period of dengue virus in Aedes aegypti

Yixin H. Ye, Stephen F. Chenoweth, Alison M. Carrasco, Scott Lee Allen, Francesca D. Frentiu, Andrew F. Van Den Hurk, Nigel W. Beebe & Elizabeth A. McGraw
Dengue fever is the most common arboviral disease worldwide. It is caused by dengue viruses (DENV) and the mosquito Aedes aegypti is its primary vector. One of the most powerful determinants of a mosquito's ability to transmit DENV is the length of the extrinsic incubation period (EIP), the time it takes for a virus to be transmitted by a mosquito after consuming an infected blood meal. Here, we repeatedly measured DENV load in the saliva...

Data from: Netted crop covers reduce honey bee foraging activity and colony strength in a mass flowering crop

Lisa J. Evans, Brian T. Cutting, Mateusz Jochym, Milena A. Janke, Crystal Felman, Sarah Cross, Marine Jacob & Mark Goodwin
The widespread use of protective covers in horticulture represents a novel landscape-level change, presenting challenges for crop pollination. Honey bees (Apis mellifera L) are pollinators of many crops, but their behaviour can be affected by conditions under covers. To determine how netting crop covers can affect honey bee foraging dynamics, colony health, and pollination services, we assessed the performance of 52 nucleus honey bee colonies in five covered and six uncovered kiwifruit orchards. Colony strength...

Hygroscopic growth and size distribution data for: In situ measurements of human cough aerosol hygroscopicity

Robert Groth, Luke Cravigan, Sadegh Niazi, Zoran Ristovski & Graham Johnson
The airborne dynamics of respiratory droplets, and the transmission routes of pathogens embedded within them, are governed primarily by the diameter of the particles. These particles are composed of the fluid which lines the respiratory tract, and is primarily mucins and salts, which will interact with the atmosphere and evaporate to reach an equilibrium diameter. Measuring organic volume fraction (OVF) of cough aerosol has proved challenging due to large variability and low material volume produced...

Data from: The linking of plate tectonics and evolutionary divergences

Matthew J. Phillips, Timothy J. Page, Mark De Bruyn, Joel A. Huey, William F. Humphreys, Jane M. Hughes, Scott R. Santos, Daniel J. Schmidt & Jonathan M. Waters
It is exciting to be living at a time when the big questions in biology can be investigated using modern genetics and computing. Bauzà-Ribot et al. take on one of the fundamental drivers of biodiversity, the effect of continental drift in the formation of the world’s biota, employing next-generation sequencing of whole mitochondrial genomes and modern Bayesian relaxed molecular clock analysis. Bauzà-Ribot et al. conclude that vicariance via plate tectonics best explains the genetic divergence...

Data from: \"454 sequencing of reduced representation libraries to discover single nucleotide polymorphisms (SNPs) in Megabunus harvestmen\" in Genomic Resources Notes accepted 1 December 2013 to 31 January 2014

Gregor Wachter, Birgit Schlick-Steiner, Florian Steiner & Wolfgang Arthofer
Harvestmen or daddy longlegs (Opiliones) are the third-largest and one of the oldest arachnid groups, and in recent years, there has been an increasing interest in this order. Here we use next-generation sequencing of reduced representation libraries to establish nuclear DNA markers. To the best of our knowledge this dataset represents the largest genomic resource for Megabunus harvestmen available to date.

Data from: PolyPatEx: an R package for paternity exclusion in autopolyploids

Alexander B. Zwart, Carole Elliott, Tara Hopley, David Lovell & Andrew Young
Microsatellite markers have demonstrated their value for performing paternity exclusion and hence exploring mating patterns in plants and animals. Methodology is well established for diploid species and several software packages exist for elucidating paternity in diploids, however these issues are not so readily addressed in polyploids due to the increased complexity of the exclusion problem and a lack of available software. We introduce PolyPatEx, an R package for paternity exclusion analysis using microsatellite data in...

Data from: Integrating local knowledge and research to refine the management of an invasive non-native grass in critically endangered grassy woodlands

Jennifer Firn, Emma Ladouceur & Josh Dorrough
1. Globally the prevalence and impact of invasive non-native plant species is increasing rapidly. Experimentally-based research aimed at supporting management is limited in its ability to keep up with this pace, partly because of the importance of understanding historical abiotic and biotic conditions. Contrastingly, landholders are in unique positions to witness species turnover in grasslands, adapt management practices in response, and learn from successes and failures. 2. This local knowledge could be crucial for identifying...

Data from: Development and field validation of a regional, management-scale habitat model: a koala Phascolarctos cinereus case study

Bradley Law, Gabriele Caccamo, Paul Roe, Anthony Truskinger, Traecey Brassil, Leroy Gonsalves, Anna McConville & Matthew Stanton
Species distribution models have great potential to efficiently guide management for threatened species, especially for those that are rare or cryptic. We used MaxEnt to develop a regional-scale model for the koala Phascolarctos cinereus at a resolution (250 m) that could be used to guide management. To ensure the model was fit for purpose, we placed emphasis on validating the model using independently-collected field data. We reduced substantial spatial clustering of records in coastal urban...

Data from: Valuable habitat and low deforestation can reduce biodiversity gains from development rights markets

Kate J. Helmstedt & Matthew D. Potts
1. Illegal private land deforestation threatens global biodiversity, even in areas with native habitat requirements stipulated by law. Compliance can be improved by allowing landholders to meet legal reserve requirements by buying and selling the rights to have deforested land through a Tradeable Development Rights system (TDR). While this policy mechanism may prevent native habitat area loss, the spatial pattern of reserved areas will shift, creating novel landscape patterns. The resulting altered fragmentation and connectivity...

Data from: Population structure of a global agricultural invasive pest, Bactrocera dorsalis (Diptera: Tephritidae)

Yu-Jia Qin, Matthew N. Krosch, Mark K. Schutze, Yue Zhang, Xiao-Xue Wang, Chandra S. Prabhakar, Agus Susanto, Alvin K.W. Hee, Sunday Ekesi, Kemo Badji, Mahfuza Khan, Yu-Bing Huang, Jia-Jiao Wu, Qiao-Ling Wang, Ge Yan, Li-Huan Zhu, Zi-Hua Zhao, Li-Jun Liu, Anthony R. Clarke, Zhi-Hong Li & Alvin K. W. Hee
Bactrocera dorsalis, the Oriental fruit fly, is one of the world’s most destructive agricultural insect pests and a major impediment to international fresh commodity trade. The genetic structuring of the species across its entire geographic range has never been undertaken, because under a former taxonomy B. dorsalis was divided into four distinct taxonomic entities, each with their own, largely non-overlapping, distributions. Based on the extensive sampling of six a priori groups from 63 locations, genetic...
