Data from: Genome-wide association analysis of type 2 diabetes in the EPIC-InterAct study

Lina Cai, Eleanor Wheeler, Nicola D. Kerrison, Jian'an Luan, Panos Deloukas, Paul W. Franks, Pilar Amiano, Eva Ardanaz, Catalina Bonet, Guy Fagherazzi, Leif C. Groop, Rudolf Kaaks, José María Huerta, Giovanna Masala, Peter M. Nilsson, Kim Overvad, Valeria Pala, Salvatore Panico, Miguel Rodriguez-Barranco, Olov Rolandsson, Carlotta Sacerdote, Matthias B. Schulze, Annemieke M.W. Spijkeman, Anne Tjonneland, Rosario Tumino … & Nicholas J. Wareham
Type 2 diabetes (T2D) is a global public health challenge. Whilst the advent of genome-wide association studies has identified >400 genetic variants associated with T2D, our understanding of its biological mechanisms and translational insights is still limited. The EPIC-InterAct project, centred in 8 countries in the European Prospective Investigations into Cancer and Nutrition study, is one of the largest prospective studies of T2D. Established as a nested case-cohort study to investigate the interplay between genetic...

Environmental drivers of Sphagnum growth in peatlands across the Holarctic region

Fia Bengtsson, Håkan Rydin, Jennifer Baltzer, Luca Bragazza, Zhao-Jun Bu, Simon Caporn, Ellen Dorrepaal, Kjell Ivar Flatberg, Olga Galanina, Mariusz Gałka, Anna Ganeva, Irina Goia, Nadezhda Goncharova, Michal Hajek, Akira Haraguchi, Lorna Harris, Elyn Humphreys, Martin Jiroušek, Katarzyna Kajukało, Edgar Karofeld, Natalia Koronatova, Natalia Kosykh, Anna Laine, Mariusz Lamentowicz, Elena Lapshina … & Richard J. Payne
The relative importance of global versus local environmental factors for growth and thus carbon uptake of the bryophyte genus Sphagnum – the main peat-former and ecosystem engineer in northern peatlands – remains unclear. 2) We measured length growth and net primary production (NPP) of two abundant Sphagnum species across 99 Holarctic peatlands. We tested the importance of previously proposed abiotic and biotic drivers for peatland carbon uptake (climate, N deposition, water table depth, and vascular...

Temporal and spatial changes in benthic invertebrate trophic networks along a salinity gradient

Julie Garrison, Marie C. Nordström, Jan Albertsson & Francisco J. A. Nascimento
Species interactions underlie all ecosystem goods and services and are important for understanding ecosystem changes. Representing one type of species interaction, trophic networks are able to be constructed from biodiversity monitoring data and known trophic links to understand how ecosystems have changed over time. The Baltic Sea is subject to high anthropogenic pressures, and its low species diversity makes it an ideal candidate for understanding how pressures change food webs. In this study, we used...

Macroclimate drives growth of hair lichens in boreal forest canopies

Nathan Phinney, Yngvar Gauslaa, Kristin Palmqvist & Per-Anders Esseen
1. Epiphytic lichens are important biodiversity components of forest canopies worldwide, significantly contributing to ecosystem function. The relative growth rate (RGR), a measure of fitness, drives population dynamics and shapes lichens’ large-scale distributions. In a climate change scenario, we need to know how external (macro- and microclimate, and nitrogen deposition), and internal factors (cortical pigments, chlorophyll and specimen size) affect RGR in these ecologically important canopy organisms. 2. We used dominant pendulous (hair) lichens widely...

Data from: Parentage and relatedness reconstruction in Pinus sylvestris using genotyping by sequencing

David Hall, Wei Zhao, Ulfstand Wennström, Bengt Andersson Gull & Xiao-Ru Wang
Estimating kinship is fundamental for studies of evolution, conservation and breeding. Genotyping-by-sequencing (GBS) and other restriction based genotyping methods have become widely applied in these applications in non-model organisms. However, sequencing errors, depth and reproducibility between library preps could potentially hinder accurate genetic inferences. In this study, we tested different sets of parameters in data filtering, different reference populations and eight estimation methods to obtain a robust procedure for relatedness estimation in Scots pine (Pinus...

Data from: Decomposition of leaf litter mixtures across biomes: The role of litter identity, diversity and soil fauna

Shixing Zhou, Olaf Butenschoen, Sandra Barantal, I. Tanya Handa, Marika Makkonen, Veronique Vos, Rien Aerts, Matty P. Berg, Brendan McKie, Jasper Van Ruijven, Stephan Hättenschwiler & Stefan Scheu
1. At broad spatial scales, the factors regulating litter decomposition remain ambiguous, with the understanding of these factors largely based on studies investigating site-specific single litter species, whereas studies using multi litter species mixtures across sites are rare. 2. We exposed in microcosms containing single species and all possible mixtures of four leaf litter species differing widely in initial chemical and physical characteristics from a temperate forest to the climatic conditions of four different forests...

Combined genotype and phenotype analyses reveal patterns of genomic adaptation to local environments in the subtropical oak Quercus acutissima

Jie Gao, Zhi Long Liu, Wei Zhao, Kyle W. Tomlinson, Shang-Wen Xia, Qing-Yin Zeng, Xiao-Ru Wang & Jin Chen
Understanding the effects of the demographic dynamics and environmental heterogeneity on the genomic variation of forest species is important not only for uncovering the evolutionary history of the species but also for predicting their ability to adapt to climate change. In this study, we combined a common garden experiment with range-wide population genomics analyses to infer the demographic history and characterize patterns of local adaptation in a subtropical oak species, Quercus acutissima. We scanned about...

This dataset is grids of peatland extent, peat depth, peatland organic carbon storage, peatland total nitrogen storage and approximate extent of ombrotrophic/minerotrophic peatlands. The grids are geotiff files in 10 km pixel resolution projected in the World Azimuthal Equidistant projection. Note that the peat depth grid shows potential peat depth everywhere,also where there is no peatland cover. For files on peatland organic carbon, total nitrogen extent and extent of ombrotrophic/minerotrophic peatlands, there are separate files...

Data from: Ecological speciation in European whitefish is driven by a large‐gaped predator

Gunnar Öhlund, Mats Bodin, Karin Nilsson, Sven-Ola Öhlund, Kenyon Mobley, Alan Hudson, Mikael Peedu, Åke Brännström, Pia Bartels, Kim Præbel, Catherine Hein, Petter Johansson & Göran Englund
Lake‐dwelling fish that form species pairs/flocks characterized by body size divergence are important model systems for speciation research. Although several sources of divergent selection have been identified in these systems, their importance for driving the speciation process remains elusive. A major problem is that in retrospect, we cannot distinguish selection pressures that initiated divergence from those acting later in the process. To address this issue, we studied the initial stages of speciation in European whitefish...

A new, undescribed species of Melanocharis berrypecker from western New Guinea and the evolutionary history of the family Melanocharitidae

Borja Milá, Jade Bruxaux, Guillermo Friis, Katerina Sam, Hidayat Ashari & Christophe Thébaud
Western New Guinea remains one of the last biologically underexplored regions of the world, and much remains to be learned regarding the diversity and evolutionary history of its fauna and flora. During a recent ornithological expedition to the Kumawa Mountains in West Papua, we encountered an undescribed species of Melanocharis berrypecker (Melanocharitidae) in cloud forest at an elevation of 1200 m asl. Its main characteristics are iridescent blue-black upperparts, satin-white underparts washed lemon yellow, and...

Stochastic processes and ecological connectivity drive stream invertebrate community responses to short-term drought

Romain Sarremejane, Amélie Truchy, Brendan McKie, Heikki Mykrä, Richard Johnson, Ari Huusko, Ryan Sponseller & Timo Muotka
1. Community responses to and recovery from disturbances depend on local (e.g. presence of refuges) and regional (connectivity to recolonization sources) factors. Droughts are becoming more frequent in boreal regions, and are likely to constitute a severe disturbance for boreal stream communities where organisms largely lack adaptations to such hydrological extremes. 2. We conducted an experiment in 24 seminatural stream flumes to assess the effects of local and regional factors on the responses of benthic...

This project started in October 2015 with a crazy idea : prepare and submit a funding application for an international, multidisciplinary and non-traditional scientific outreach project… within the next 48 hours. Well, it worked out. A group of highly motivated young researchers from Canada and Europe united to combine arts and science and produce a series of outreach comic strips about permafrost (frozen ground). The aim of the project is to present and explain scientific...

Spatial point pattern analysis of traces (SPPAT): an approach for visualizing and quantifying site-selectivity patterns of drilling predators

Alexis Rojas, Gregory Dietl, Michal Kowalewski, Roger W. Portell, Austin Hendy & Jason Blackburn
Site-selectivity analysis in drilling predation may provide useful behavioral information of a predator interacting with its prey. However, traditional approaches exclude some spatial information (i.e., oversimplified trace position) and are dependent on the scale of analysis (e.g., arbitrary grid system used to divide the prey skeleton into sectors). Here we introduce the spatial point pattern analysis of traces (SPPAT), an approach for visualizing and quantifying the distribution of traces on shelled invertebrate prey, which includes...

Data from: Estimating density from presence/absence data in clustered populations

Magnus Ekström, Saskia Sandring, Anton Grafström, Per-Anders Esseen, Bengt Gunnar Jonsson & Göran Ståhl
1. Inventories of plant populations are fundamental in ecological research and monitoring, but such surveys are often prone to field assessment errors. Presence/absence (P/A) sampling may have advantages over plant cover assessments for reducing such errors. However, the linking between P/A data and plant density depends on model assumptions for plant spatial distributions. Previous studies have shown, for example, how that plant density can be estimated under Poisson model assumptions on the plant locations. In...

Supplementary materials for: Long term effects of cholinesterase inhibitors on cognitive decline and mortality

Hong Xu, Sara Garcia-Ptacek, Linus Jönsson, Wimo Anders, Nordström Peter & Maria Eriksdotter
Objective: Cholinesterase inhibitors (ChEIs) are the mainstay treatment of Alzheimer’s dementia (AD), but their long-term effectiveness is uncertain. This study aims is to investigate whether ChEIs are associated with slower cognitive decline in AD, and decreased risk of severe dementia or death. Methods: AD patients from the Swedish Dementia Registry (SveDem) starting on ChEIs within three months of the dementia diagnosis were included and compared to non-treated AD patients. In a propensity score matched cohort,...
