Data from: Plant functional groups mediate drought resistance and recovery in a multi-site grassland experiment

Kathleen A. Mackie, Michaela Zeiter, Juliette M.G. Bloor, Andreas Stampfli & Juliette M. G. Bloor
1. Climate change predictions suggest that summer droughts will become more intense and recurrent in Europe. While drought-induced reductions in grassland primary productivity are well documented, the drivers behind drought resistance (the capacity to withstand change) and recovery (the capacity for recovery of function) of above- and belowground biomass remain poorly understood. 2. Across eight grasslands differing in plant community productivity (CP) we investigated the effects of summer drought on plant and soil microbial variables,...

Host specificity and species colouration mediate the regional decline of nocturnal moths in central European forests

Nicolas Roth, Herrman Hacker, Lea Heidrich, Nicolas Friess, Enrique García-Barros, Jan Habel, Simon Thorn & Jörg Müller
The high diversity of insects has limited the volume of long-term community data with a high taxonomic resolution and considerable geographic replications, especially in forests. Therefore, trends and causes of changes are poorly understood. Here we analyse trends in species richness, abundance and biomass of nocturnal macro moths in three quantitative data sets collected over four decades in forests in southern Germany. Two local data sets, one from coppiced oak forests and one from high...

Metabarcoding of canopy arthropods reveals negative impacts of forestry insecticides on community structure across multiple taxa

Benjamin Leroy, Sebastian Seibold, Jérôme Morinière, Vedran Bozicevic, Jessica Jaworek, Nicolas Roth, Sebastian Vogel, Sharon Zytynska, Ralf Petercord, Peter Eichel & Wolfgang Weisser
1. Insecticides used to combat outbreaks of forest defoliators can adversely affect non-target arthropods. Forest use insecticides typically suppress Lepidoptera larvae which are the keystone of the canopy community of deciduous oak forests. The abrupt removal of this dominant component of the food web could have far-reaching implications for forest ecosystems, yet it is rarely investigated in practice owing to several methodological shortcomings. The taxonomic impediment and the biased nature of arthropod sampling techniques particularly...

The impact of seat-height on 1-minute sit to stand test performance in COPD: A randomised cross-over trial

Valerie Zumbrunnen, Thomas Riegler, Sarah Haile & Thomas Radtke
Study question: Is there a difference in the number of repetitions on the 1-minute sit to stand (1MSTS) test using an individually adapted seatheight to 90-degree knee flexion (1MSTSIND), compared with the commonly used standard chair seat-height of 46cm (1MSTSSTD), in people with COPD. Intervention: After a learning 1MSTS, all participants performed two 1MSTS tests in random order on consecutive days. Participants were blinded, as they did not receive detailed information on the testing protocols....

Data from: Genetic diversity analyses reveal first insights into breed-specific selection signatures within Swiss goat breeds

Alexander Burren, Markus Neuditschko, Heidi Signer-Hasler, Mirjam Frischknecht, Irene Reber, Fiona Menzi, Cord Drögemüller & Christine Flury
We used genotype data from the caprine 50k Illumina BeadChip for the assessment of genetic diversity within and between 10 local Swiss goat breeds. Three different cluster methods allowed the goat samples to be assigned to the respective breed groups, whilst the samples of Nera Verzasca and Tessin Grey goats could not be differentiated from each other. The results of the different genetic diversity measures show that Appenzell, Toggenburg, Valais and Booted goats should be...

Data from: Species richness effects on grassland recovery from drought depend on community productivity in a multisite experiment

Biodiversity can buffer ecosystem functioning against extreme climatic events, but few experiments have explicitly tested this. Here, we present the first multisite biodiversity × drought manipulation experiment to examine drought resistance and recovery at five temperate and Mediterranean grassland sites. Aboveground biomass production declined by 30% due to experimental drought (standardised local extremity by rainfall exclusion for 72–98 consecutive days). Species richness did not affect resistance but promoted recovery. Recovery was only positively affected by...

Data from: Evolution without standing genetic variation: change in transgenerational plastic response under persistent predation pressure

Arnaud Sentis, Raphaël Bertram, Nathalie Dardenne, Felipe Ramon-Portugal, Gilles Espinasse, Ines Louit, Lucie Negri, Elena Haeler, Thomas Ashkar, Théo Pannetier, James Cunningham, Christoph Grunau, Gaël Le Trionnaire, Jean-Christophe Simon, Alexandra Margo, Benoit Pujol, Jean-Louis Hemptinne & Etienne Danchin
Transgenerational phenotypic plasticity is a fast nongenetic response to environmental modifications that can buffer the effects of environmental stresses on populations. However, little is known about the evolution of plasticity in the absence of standing genetic variation although several nongenetic inheritance mechanisms have now been identified. Here, we monitored the pea aphid transgenerational phenotypic response to ladybird predators (production of winged offspring) during 27 generations of experimental evolution in the absence of initial genetic variation...

Data from: Bioclimatic envelope models predict a decrease in tropical forest carbon stocks with climate change in Madagascar

Ghislain Vieilledent, Oliver Gardi, Clovis Grinand, Christian Burren, Mamitiana Andriamanjato, Christian Camara, Charlie J. Gardner, Leah Glass, Andriambolantsoa Rasolohery, Harifidy Ratsimba, Valéry Gond & Jean-Roger Rakotoarijaona
1. Recent studies have underlined the importance of climatic variables in determining tree height and biomass in tropical forests. Nonetheless, the effects of climate on tropical forest carbon stocks remain uncertain. In particular, the application of process-based dynamic global vegetation models have led to contrasting conclusions regarding the potential impact of climate change on tropical forest carbon storage. 2. Using a correlative approach based on a bioclimatic envelope model and data from 1771 forest plots...

Milk production and environmental conditions of mountain-pastured Braunvieh cows between 2000 and 2015

Solange Duruz & Christine Flury
This dataset is a subset of the dataset used in the associated article, linking environmental data to milk records of mountain-pastured cows between 2000 and 2015. In particular it contains information on the cow and lactation cycle (lactation number, date of calving, date of first record in the alp, average quantity of milk over 3 milk records taken in the alp) and environmental condition (temperature humidity index, cold stress index, averaged over 3 and 30...

Data from: Patterns and drivers of biodiversity-stability relationships under climate extremes

Hans J. De Boeck, Juliette M. G. Bloor, Juergen Kreyling, Johannes C. G. Ransijn, Ivan Nijs, Anke Jentsch & Michaela Zeiter
Interactions between biodiversity loss and climate change present significant challenges for research, policy and management of ecosystems. Evidence suggests that high species diversity tends to increase plant community stability under interannual climate fluctuations and mild dry and wet events, but the overall pattern of diversity–stability relationships under climate extremes is unclear. We comprehensively review results from observational and experimental studies to assess the importance of diversity effects for ecosystem function under climate extremes. Both the...
