Data from: Spatially structured statistical network models for landscape genetics

Erin E. Peterson, Ephraim M. Hanks, Mevin B. Hooten, Jay M. Ver Hoef & Marie-Josée Fortin
A basic understanding of how the landscape impedes, or creates resistance to, the dispersal of organisms and hence gene flow is paramount for successful conservation science and management. Spatially structured ecological networks are often used to represent spatial landscape-genetic relationships, where nodes represent individuals or populations and resistance to movement is represented using non-binary edge weights. Weights are typically assigned or estimated by the user, rather than observed, and validating such weights is challenging. We...

Data from: Climate modifies response of non-native and native species richness to nutrient enrichment

Habacuc Flores-Moreno, Peter B. Reich, Eric M. Lind, Lauren L. Sullivan, Eric W. Seabloom, Laura Yahdjian, Andrew S. MacDougall, Lara G. Reichmann, Juan Alberti, Selene Báez, Jonathan D. Bakker, Marc W. Cadotte, Maria C. Caldeira, Enrique J. Chaneton, Carla M. D'Antonio, Philip A. Fay, Jennifer Firn, Nicole Hagenah, W. Stanley Harpole, Oscar Iribarne, Kevin P. Kirkman, Johannes M. H. Knops, Kimberly J. La Pierre, Ramesh Laungani, Andrew D. B. Leakey … & Elizabeth T. Borer
Ecosystem eutrophication often increases domination by non-natives and causes displacement of native taxa. However, variation in environmental conditions may affect the outcome of interactions between native and non-native taxa in environments where nutrient supply is elevated. We examined the interactive effects of eutrophication, climate variability and climate average conditions on the success of native and non-native plant species using experimental nutrient manipulations replicated at 32 grassland sites on four continents. We hypothesized that effects of...

Data from: Age and area predict patterns of species richness in pumice rafts contingent on oceanic climatic zone encountered

Eleanor Velasquez, Scott E. Bryan, Merrick Ekins, Alex G. Cook, Lucy Hurrey & Jennifer Firn
The Theory of Island Biogeography predicts that area and age explain species richness patterns (or alpha diversity) in insular habitats. Using a unique natural phenomenon, pumice rafting, we measured the influence of area, age and oceanic climate on patterns of species richness. Pumice rafts are formed simultaneously when submarine volcanoes erupt, the pumice clasts break-up irregularly, forming irregularly shaped pumice stones which while floating through the ocean are colonised by marine biota. We analyse two...

Hull fouling marine invasive species pose a very low, but plausible, risk of introduction to East Antarctica in climate change scenarios

Oakes Holland, Justine Shaw, Jonathan Stark & Kerrie Wilson
Aims: To identify potential hull fouling marine invasive species that could survive in East Antarctica presently and in the future. Location: Australia's Antarctic continental stations: Davis, Mawson and Casey, East Antarctica; and subantarctic islands: Macquarie Island and Heard and McDonald Islands. Methods: Our study uses a novel machine-learning algorithm to predict which currently known hull fouling MIS could survive in shallow benthic ecosystems adjacent to Australian Antarctic research stations and subantarctic islands, where ship traffic...

Data from: Systematic review: unmet supportive care needs in people diagnosed with chronic liver disease

Patricia C. Valery, Elizabeth Powell, Neta Moses, Michael Volk, Steven M. McPhail, Paul Clark & Jennifer Martin
Objective: People with chronic liver disease, particularly those with decompensated cirrhosis, experience several potentially debilitating complications that can have a significant impact on activities of daily living and quality of life. These impairments combined with the associated complex treatment mean that they are faced with specific and high levels of supportive care needs. We aimed to review reported perspectives, experiences and concerns of people with chronic liver disease worldwide. This information is necessary to guide...

Data from: Can impacts of climate change and agricultural adaptation strategies be accurately quantified if crop models are annually re-initialized?

Bruno Basso, David W. Hyndman, Anthony D. Kendall, Peter R. Grace & G. Philip Robertson
Estimates of climate change impacts on global food production are generally based on statistical or process-based models. Process-based models can provide robust predictions of agricultural yield responses to changing climate and management. However, applications of these models often suffer from bias due to the common practice of re-initializing soil conditions to the same state for each year of the forecast period. If simulations neglect to include year-to-year changes in initial soil conditions and water content...

Data from: Incidence and fatality of serious suicide attempts in a predominantly rural population in Shandong, China: a public health surveillance study

Jiandong Sun, Xiaolei Guo, Jiyu Zhang, Mei Wang, Cunxian Jia & Aiqiang Xu
Objectives: To estimate the incidence of serious suicide attempts (SSAs, defined as suicide attempts resulting in either death or hospitalisation) and to examine factors associated with fatality among these attempters. Design: A surveillance study of incidence and mortality. Linked data from two public health surveillance systems were analysed. Setting: Three selected counties in Shandong, China. Participants: All residents in the three selected counties. Outcome: measures Incidence rate (per 100 000 person-years) and case fatality rate...

Data from: Sharing is caring? measurement error and the issues arising from combining 3D morphometric datasets

Carmelo Fruciano, Melina A. Celik, Kaylene Butler, Tom Dooley, Vera Weisbecker & Matthew J. Phillips
Geometric morphometrics is routinely used in ecology and evolution and morphometric datasets are increasingly shared among researchers, allowing for more comprehensive studies and higher statistical power (as a consequence of increased sample size). However, sharing of morphometric data opens up the question of how much nonbiologically relevant variation (i.e., measurement error) is introduced in the resulting datasets and how this variation affects analyses. We perform a set of analyses based on an empirical 3D geometric...

Data from: Are sympatrically speciating Midas cichlid fish special? Patterns of morphological and genetic variation in the closely related species Archocentrus centrarchus

Carmelo Fruciano, Paolo Franchini, Francesca Raffini, Shaohua Fan & Axel Meyer
Established empirical cases of sympatric speciation are scarce, although there is an increasing consensus that sympatric speciation might be more common than previously thought. Midas cichlid fish are one of the few substantiated cases of sympatric speciation, and they formed repeated radiations in crater lakes. In contrast, in the same environment, such radiation patterns have not been observed in other species of cichlids and other families of fish. We analyze morphological and genetic variation in...

Dominant native and non-native graminoids differ in key leaf traits irrespective of nutrient availability

Arthur Broadbent, Jennifer Firn, James McGree, Elizabeth Borer, Yvonne Buckley, W. Stanley Harpole, Kimberly Komatsu, Andrew MacDougall, Kate Orwin, Nicholas Ostle, Eric Seabloom, Jonathan Bakker, Lori Biedermann, Maria Caldeira, Nico Eisenhauer, Nicole Hagenah, Yann Hautier, Joslin Moore, Carla Nogueira, Pablo Peri, Anita Risch, Christiane Roscher, Martin Schuetz & Carly Stevens
Aim Nutrient enrichment is associated with plant invasions and biodiversity loss. Functional trait advantages may predict the ascendancy of invasive plants following nutrient enrichment but this is rarely tested. Here, we investigate 1) whether dominant native and non-native plants differ in important morphological and physiological leaf traits, 2) how their traits respond to nutrient addition, and 3) whether responses are consistent across functional groups. Location Australia, Europe, North America and South Africa Time period 2007...
