Data from: Environmental changes drive the temporal stability of semi-arid natural grasslands through altering species asynchrony

Zhuwen Xu, Haiyan Ren, Mai-He Li, Jasper Van Ruijven, Xingguo Han, Shiqiang Wan, Hui Li, Qiang Yu, Yong Jiang & Lin Jiang
Stability is an important property of ecological systems, many of which are experiencing increasing levels of anthropogenic environmental changes. However, how these environmental changes influence ecosystem stability remains poorly understood. We conducted an 8-year field experiment in a semi-arid natural grassland to explore the effects of two common environmental changes, precipitation and nitrogen enrichment, on the temporal stability of plant above-ground biomass. A split-plot design, with precipitation as the main plot factor and nitrogen as...

Data from: Functional responses of multi-taxa communities to disturbance and stress gradients in a restored floodplain

Bertrand Fournier, François Gillet, Renée-Claire Le Bayon, Edward A. D. Mitchell & Marco Moretti
1. Trait-based approaches can reveal the mechanisms through which disturbances or stress impact communities, allowing comparisons of the role of different mechanisms in shaping communities among taxonomic groups. Such information can lead to higher comparability, transferability and predictability of the outcome of restoration projects. However, multitaxa trait-based approaches were rarely used in the context of ecosystem restoration. 2. We investigated the responses to environmental gradients of seven taxa (vascular plants, staphylinid and carabid beetles, spiders,...

Data from: Efficient detection of novel nuclear markers for Brassicaceae by transcriptome sequencing

Reinhold Stockenhuber, Stefan Zoller, Rie Shimizu-Inatsugi, Felix Gugerli, Kentaro K. Shimizu, Alex Widmer & Martin C. Fischer
The lack of DNA sequence information for most non-model organisms impairs the design of primers that are universally applicable for the study of molecular polymorphisms in nuclear markers. Next-generation sequencing (NGS) techniques nowadays provide a powerful approach to overcome this limitation. We present a flexible and inexpensive method to identify large numbers of nuclear primer pairs that amplify in most Brassicaceae species. We first obtained and mapped NGS transcriptome sequencing reads from two of the...

Data from: Peatland vascular plant functional types affect methane dynamics by altering microbial community structure

Bjorn J. M. Robroek, Vincent E. J. Jassey, Martine A. R. Kox, Roeland L. Berendsen, Robert T. E. Mills, Lauric Cécillon, Jéremy Puissant, Marion Meima–Franke, Peter A. H. M. Bakker, Paul L. E. Bodelier & Marion Meima-Franke
1. Peatlands are natural sources of atmospheric methane (CH4), an important greenhouse gas. It is established that peatland methane dynamics are controlled by both biotic and abiotic conditions, yet the interactive effect of these drivers is less studied and consequently poorly understood. 2. Climate change affects the distribution of vascular plant functional types (PFTs) in peatlands. By removing specific PFTs, we assessed their effects on peat organic matter chemistry, microbial community composition and on potential...

Data from: Subordinate plants mitigate drought effects on soil ecosystem processes by stimulating fungi

Pierre Mariotte, Bjorn J. M. Robroek, Vincent E. J. Jassey & Alexandre Buttler
The subordinate insurance hypothesis suggests that highly diverse communities contain greater numbers of subordinate species than less diverse communities. It has previously been reported that subordinate species can improve grassland productivity during drought, but the underlying mechanisms remain undetermined. Using a combination of subordinate species removal and summer drought, we show that soil processes play a critical role in community resistance to drought. Interestingly, subordinate species drive soil microbial community structure and largely mitigate the...

Data from: Biological introduction threats from shipping in a warming Arctic

Chris Ware, Jørgen Berge, Anders Jelmert, Steffen M. Olsen, Loïc Pellissier, Mary Wisz, Darren Kriticos, Georgy Semenov, Slawomir Kwasniewski & Inger G. Alsos
Several decades of research on invasive marine species have yielded a broad understanding of the nature of species invasion mechanisms and associated threats globally. However, this is not true of the Arctic, a region where ongoing climatic changes may promote species invasion. Here, we evaluated risks associated with non-indigenous propagule loads discharged with ships' ballast water to the high-Arctic archipelago, Svalbard, as a case study for the wider Arctic. We sampled and identified transferred propagules...

Data from: Cold temperature extremes during spring do not limit the range shift of Mediterranean pines into regions with intermittent frost

Christoph Bachofen, Thomas Wohlgemuth, Jaboury Ghazoul & Barbara Moser
Bioclimatic envelope models have predicted latitudinal range shifts of tree species in Europe following climate change. Accordingly, Mediterranean species will be able to migrate northwards if climatic conditions become warmer and dryer. Frost, on the other hand, is an important and recurring factor in temperate and boreal regions causing damage to buds and leaves, and potentially limiting the survival of Mediterranean tree species or populations at higher latitudes. Since species distribution models rely on average...

Data from: Convergent losses of decay mechanisms and rapid turnover of symbiosis genes in mycorrhizal mutualists

Annegret Kohler, Alan Kuo, Laszlo G. Nagy, Emmanuelle Morin, Kerrie W. Barry, Francois Buscot, Bjorn Canback, Cindy Choi, Nicolas Cichocki, Alicia Clum, Jan Colpaert, Alex Copeland, Mauricio D. Costa, Jeanne Dore, Dimitrios Floudas, Gilles Gay, Mariangela Girlanda, Bernard Henrissat, Sylvie Herrmann, Jaqueline Hess, Nils Hogberg, Tomas Johansson, Hassine-Radhouane Khouja, Kurt LaButti, Urs Lahrmann … & Francis Martin
To elucidate the genetic bases of mycorrhizal lifestyle evolution, we sequenced new fungal genomes, including 13 ectomycorrhizal (ECM), orchid (ORM) and ericoid (ERM) species, and five saprotrophs, which we analyzed along with other fungal genomes. Ectomycorrhizal fungi have a reduced complement of genes encoding plant cell wall–degrading enzymes (PCWDEs), as compared to their ancestral wood decayers. Nevertheless, they have retained a unique array of PCWDEs, thus suggesting that they possess diverse abilities to decompose lignocellulose....

Data from: The response of the alpine dwarf shrub Salix herbacea to altered snowmelt timing: lessons from a multi-site transplant experiment

Janosch Sedlacek, Julia A. Wheeler, Andrés J. Cortés, Oliver Bossdorf, Guenter Hoch, Christian Lexer, Sonja Wipf, Sophie Karrenberg, Mark Van Kleunen & Christian Rixen
Climate change is altering spring snowmelt patterns in alpine and arctic ecosystems, and these changes may alter plant phenology, growth and reproduction. To predict how alpine plants respond to shifts in snowmelt timing, we need to understand trait plasticity, its effects on growth and reproduction, and the degree to which plants experience a home-site advantage. We tested how the common, long-lived dwarf shrub Salix herbacea responded to changing spring snowmelt time by reciprocally transplanting turfs...

Data from: Soil nutrients influence growth response of temperate tree species to drought

Mathieu Lévesque, Lorenz Walthert & Pascale Weber
Soil properties can buffer forest response to global climate change. However, it is unclear how soil characteristics, water availability and their interactions can affect drought response of trees. The aim of this study was to assess the influence of soil nutrients and physical soil properties on the growth sensitivity of Fagus sylvatica, Quercus spp., Fraxinus excelsior, Abies alba, Picea abies and Pinus sylvestris to drought in Central Europe. Yearly growth data from increment cores were...
