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: Nature of the coupling between neural drive and force-generating capacity in the human quadriceps muscle

François Hug, Clément Goupille, Daniel Baum, Brent Raiteri, Paul Hodges, Kylie Tucker, Paul W. Hodges & Brent J. Raiteri
The force produced by a muscle depends on both the neural drive it receives and several biomechanical factors. When multiple muscles act on a single joint the nature of the relationship between the neural drive and force-generating capacity of the synergistic muscles is largely unknown. This study aimed to determine the relationship between the ratio of neural drive and the ratio of muscle force-generating capacity between two synergist muscles (vastus lateralis[VL] and medialis[VM]) in humans....

Data from: Mother-offspring distances reflect sex differences in fine-scale genetic structure of eastern grey kangaroos

Wendy J. King, Dany Garant & Marco Festa-Bianchet
Natal dispersal affects life history and population biology and causes gene flow. In mammals, dispersal is usually male-biased so that females tend to be philopatric and surrounded by matrilineal kin, which may lead to preferential associations among female kin. Here we combine genetic analyses and behavioral observations to investigate spatial genetic structure and sex-biased dispersal patterns in a high-density population of mammals showing fission–fusion group dynamics. We studied eastern grey kangaroos (Macropus giganteus) over 2...

Data from: Relative deprivation and relative wealth enhances anti-immigrant sentiments: the v-curve re-examined

Jolanda Jetten, Frank Mols & Tom Postmes
Previous research has shown that negative attitudes towards immigrants and support for anti-immigrant parties are observed both among those experiencing relative deprivation and those experiencing relative gratification (so called v-curve). Whereas the effect of relative deprivation is intuitive, the effect of relative gratification is more difficult to explain. Why would economic prosperity provoke negative attitudes towards immigrants? We first present correlational (Study 1) and experimental (Study 2) support for the v-curve. In Study 1, in...

Data from: Towards automated annotation of benthic survey images: variability of human experts and operational modes of automation

Oscar Beijbom, Peter J. Edmunds, Chris Roelfsema, Jennifer Smith, David I. Kline, Benjamin Neal, Matthew J. Dunlap, Vincent Moriarty, Tung-Yung Fan, Chih-Jui Tan, Stephen Chan, Tali Treibitz, Anthony Gamst, B. Greg Mitchell, David Kriegman & Benjamin P. Neal
Global climate change and other anthropogenic stressors have heightened the need to rapidly characterize ecological changes in marine benthic communities across large scales. Digital photography enables rapid collection of survey images to meet this need, but the subsequent image annotation is typically a time consuming, manual task. We investigated the feasibility of using automated point-annotation to expedite cover estimation of the 17 dominant benthic categories from survey-images captured at four Pacific coral reefs. Inter- and...

Data from: Direct and indirect effects of nursery habitats on coral-reef fish assemblages, grazing pressure, and benthic dynamics

Alastair R. Harborne, Ivan Nagelkerken, Nicholas H. Wolff, Yves-Marie Bozec, Martijn Dorenbosch, Monique G. G. Grol & Peter J. Mumby
Migrating species are common within seascapes, but the potential for these movements to alter the populations and functional roles of non-migrating species (e.g. by increasing predation) is rarely investigated. This study considers whether the presence of nursery habitats (mangroves and seagrass) simply enhances the abundance of nursery-using parrotfishes and piscivores on nearby coral reefs, or also affects other parrotfishes. Data from 131 reef sites and multiple seascape configurations across 13 degrees of latitude were used...

Data from: Ocean acidification induces biochemical and morphological changes in the calcification process of large benthic foraminifera

Martina De Freitas Prazeres, Sven Uthicke, John M. Pandolfi & M. Prazeres
Large benthic foraminifera are significant contributors to sediment formation on coral reefs, yet they are vulnerable to ocean acidification. Here, we assessed the biochemical and morphological impacts of acidification on the calcification of Amphistegina lessonii and Marginopora vertebralis exposed to different pH conditions. We measured growth rates (surface area and buoyant weight) and Ca-ATPase and Mg-ATPase activities and calculated shell density using micro-computer tomography images. In A. lessonii, we detected a significant decrease in buoyant...

Data from: Reef flattening effects on total richness and species responses in the Caribbean

Steven P. Newman, Erik H. Meesters, Charlie S. Dryden, Stacey M. Williams, Cristina Sanchez, Peter J. Mumby, Nicholas V.C. Polunin & Nicholas V. C. Polunin
1. There has been ongoing flattening of Caribbean coral reefs with the loss of habitat having severe implications for these systems. Complexity and its structural components are important to fish species richness and community composition, but little is known about its role for other taxa or species-specific responses. 2. This study reveals the importance of reef habitat complexity and structural components to different taxa of macrofauna, total species richness, and individual coral and fish species...

Data from: Why does offspring size affect performance? Integrating metabolic scaling with life-history theory

Amanda K. Pettersen, Craig R. White & Dustin J. Marshall
Within species, larger offspring typically outperform smaller offspring. While the relationship between offspring size and performance is ubiquitous, the cause of this relationship remains elusive. By linking metabolic and life-history theory, we provide a general explanation for why larger offspring perform better than smaller offspring. Using high-throughput respirometry arrays, we link metabolic rate to offspring size in two species of marine bryozoan. We found that metabolism scales allometrically with offspring size in both species: while...

Data from: Strong and stable geographic differentiation of swamp buffalo maternal and paternal lineages indicates domestication in the China/Indochina border region

Yi Zhang, Yongfang Lu, Marnoch Yindee, Kuan-Yi Li, Hsiao-Yun Kuo, Yu-Ten Ju, Shaohui Ye, , Qiang Li, Yachun Wang, Vu Chi Cuong, Lan Doan Pham, Bounthong Bouahom, Bingzhuang Yang, Xianwei Liang, Zhihua Cai, Dianne Vankan, Wallaya Manatchaiworakul, Nonglid Kowlim, Somphot Duangchantrasiri, Worawidh Wajjwalku, Ben Colenbrander, Yuan Zhang, Peter Beerli, Johannes A. Lenstra … & J. Stuart F. Barker
The swamp type of the Asian water buffalo is assumed to have been domesticated by about 4000 years BP, following the introduction of rice cultivation. Previous localizations of the domestication site were based on mitochondrial DNA (mtDNA) variation within China, accounting only for the maternal lineage. We carried out a comprehensive sampling of China, Taiwan, Vietnam, Laos, Thailand, Nepal and Bangladesh and sequenced the mtDNA Cytochrome b gene and control region and the Y-chromosomal ZFY,...

Data from: Replicated analysis of the genetic architecture of quantitative traits in two wild great tit populations

Anna W. Santure, Jocelyn Poissant, Isabelle De Cauwer, Kees Van Oers, Matthew R. Robinson, John L. Quinn, Martien A. M. Groenen, Marcel E. Visser, Ben C. Sheldon & Jon Slate
Currently there is much debate on the genetic architecture of quantitative traits in wild populations. Is trait variation influenced by many genes of small effect or by a few genes of major effect? Where is additive genetic variation located in the genome? Do the same loci cause similar phenotypic variation in different populations? Great tits (Parus major) have been studied extensively in long-term studies across Europe, and consequently are considered an ecological 'model organism'. Recently,...

Data from: Prioritizing management actions for invasive populations using cost, efficacy, demography, and expert opinion for 14 plant species worldwide

Natalie Z. Kerr, Peter W. J. Baxter, Roberto Salguero-Gomez, Glenda M. Wardle, Yvonne M. Buckley & Peter W.J. Baxter
Management of invasive populations is typically investigated case-by-case. Comparative approaches have been applied to single aspects of management, such as demography, with cost or efficacy rarely incorporated. We present an analysis of the ranks of management actions for 14 species in five countries that extends beyond the use of demography alone to include multiple metrics for ranking management actions, which integrate cost, efficacy and demography (cost-effectiveness) and managers’ expert opinion of ranks. We use content...

Data from: The role of defensive ecological interactions in the evolution of conotoxins

Jutty Rajan Prashanth, Sebastien Dutertre, Ai-Hua Jin, Vincent Lavergne, Brett Hamilton, Fernanda C. Cardoso, John Griffin, Deon J. Venter, Paul F. Alewood, Richard J. Lewis & A. H. Jin
Venoms comprise of complex mixtures of peptides evolved for predation and defensive purposes. Remarkably, some carnivorous cone snails can inject two distinct venoms in response to predatory or defensive stimuli, providing a unique opportunity to study separately how different ecological pressures contribute to toxin diversification. Here, we report the extraordinary defensive strategy of the Rhizoconus subgenus of cone snails. The defensive venom from this worm-hunting subgenus is unusually simple, almost exclusively composed of αD-conotoxins instead...

Data from: Sensitivity analysis of conservation targets in systematic conservation planning

Noam Levin, Tessa Mazor, Eran Brokovich, Pierre-Elie Jablon & Salit Kark
Systematic conservation planning has rapidly advanced in the past decade and has been increasingly incorporated in multiple studies and conservation projects. One of its requirements is a quantitative definition of conservation targets. While the Convention on Biological Diversity aims to expand the world's protected area network to 17% of the land surface, in many cases such uniform policy-driven targets may not be appropriate for achieving persistence of various species. Targets are often set arbitrarily, often...

Data from: Heterogeneity of genetic architecture of body size traits in a free-living population

Camillo Bérénos, Philip A. Ellis, Jill G. Pilkington, S. Hong Lee, Jake Gratten & Josephine M. Pemberton
Knowledge of the underlying genetic architecture of quantitative traits could aid in understanding how they evolve. In wild populations, it is still largely unknown whether complex traits are polygenic or influenced by few loci with major effect, due to often small sample sizes and low resolution of marker panels. Here, we examine the genetic architecture of five adult body size traits in a free-living population of Soay sheep on St Kilda using 37 037 polymorphic...
