Data from: Spatial and temporal aridity gradients provide poor proxies for plant-plant interactions under climate change: a large-scale experiment

Johannes Metz & Katja Tielbörger
1. Plant-plant interactions may critically modify the impact of climate change on plant communities. However, the magnitude and even direction of potential future interactions remains highly debated, especially for water limited ecosystems. Predictions range from increasing facilitation to increasing competition with future aridification. 2. The different methodologies used for assessing plant-plant interactions under changing environmental conditions may affect the outcome but they are not equally represented in the literature. Mechanistic experimental manipulations are rare compared...

Data from: Scale-dependent role of demography and dispersal on the distribution of populations in heterogeneous landscapes

Benjamin T. Martin, Sergiusz Czesny, David H. Wahl & Volker Grimm
Both dispersal and local demographic processes determine a population's distribution among habitats of varying quality, yet most theory, experiments, and field studies have focused on the former. We use a generic model to show how both processes contribute to a population's distribution, and how the relative importance of each mechanism depends on scale. In contrast to studies only considering habitat-dependent dispersal, we show that predictions of ideal free distribution (IFD) theory are relevant even at...

Data from: Community- weighted mean plant traits predict small scale distribution of insect root herbivore abundance

Ilja Sonnemann, Hans Pfestorf, Florian Jeltsch & Susanne Wurst
Small scale distribution of insect root herbivores may promote plant species diversity by creating patches of different herbivore pressure. However, determinants of small scale distribution of insect root herbivores, and impact of land use intensity on their small scale distribution are largely unknown. We sampled insect root herbivores and measured vegetation parameters and soil water content along transects in grasslands of different management intensity in three regions in Germany. We calculated community-weighted mean plant traits...

Data from: Paternal intergenerational epigenetic response to heat exposure in male Wild guinea pigs

Alexandra Weyrich, Dorina Lenz, Marie Jeschek, Tzu Hung Chung, Kathrin Ruebensam, Frank Goeritz, Katarina Jewgenow & Joerns Fickel
Epigenetic modifications, of which DNA methylation is the best studied one, can convey environmental information through generations via parental germ lines. Past studies have focused on the maternal transmission of epigenetic information to the offspring of isogenic mice and rats in response to external changes, whereas heterogeneous wild mammals as well as paternal epigenetic effects have been widely neglected. In most wild mammal species, males are the dispersing sex and have to cope with differing...

Data from: Parental environmental effects due to contrasting watering adapt competitive ability, but not drought tolerance, in offspring of a semi-arid annual Brassicaceae

Johannes Metz, Jonathan Von Oppen & Katja Tielbörger
1. Parental effects (PE) can be adaptive and improve offspring performance when parents and offspring experience similar environmental conditions. However, it is unknown whether adaptive PE exist also in habitats where such similarity is unlikely due to strong temporal variation. In particular, we do not know whether PE can adapt offspring to fluctuating levels of neighbour competition in such habitats. 2. Here, we tested for adaptive PE in terms of two key environmental factors in...

Data from: Impact of enrichment conditions on cross-species capture of fresh and degraded DNA

Johanna L. A. Paijmans, Joerns Fickel, Alexandre Courtiol, Michael Hofreiter & Daniel W. Förster
By combining high-throughput sequencing with target-enrichment (“hybridization capture”), researchers are able to obtain molecular data from genomic regions of interest for projects that are otherwise constrained by sample quality (e.g. degraded and contamination-rich samples) or a lack of a priori sequence information (e.g. studies on non-model species). Despite the use of hybridization capture in various fields of research for many years, the impact of enrichment conditions on capture success are not yet thoroughly understood. We...

Data from: Species richness, but not phylogenetic diversity, influences community biomass production and temporal stability in a re-examination of 16 grassland biodiversity studies

Patrick Venail, Kevin Gross, Todd H. Oakley, Anita Narwani, Eric Allan, Pedro Flombaum, Forest Isbell, Jasmin Joshi, Peter B. Reich, David Tilman, Jasper Van Ruijven & Bradley J. Cardinale
1.Hundreds of experiments have now manipulated species richness of various groups of organisms and examined how this aspect of biological diversity influences ecosystem functioning. Ecologists have recently expanded this field to look at whether phylogenetic diversity among species, often quantified as the sum of branch lengths on a molecular phylogeny leading to all species in a community, also predicts ecological function. Some have hypothesized that phylogenetic divergence should be a superior predictor of ecological function...

Data from: Climate impacts on trans-ocean dispersal and habitat in gray whales from the Pleistocene to 2100

S. Elizabeth Alter, Matthias Meyer, Klaas Post, Paul Czechowski, Peter Gravlund, Cork Gaines, Howard C. Rosenbaum, Kristin Kaschner, Samuel T. Turvey, Johannes Van Der Plicht, Beth Shapiro & Michael Hofreiter
Arctic animals face dramatic habitat alteration due to ongoing climate change. Understanding how such species have responded to past glacial cycles can help us forecast their response to today's changing climate. Gray whales are among those marine species likely to be strongly affected by Arctic climate change, but a thorough analysis of past climate impacts on this species has been complicated by lack of information about an extinct population in the Atlantic. While little is...

Data from: Seed dispersal by ungulates as an ecological filter: a trait-based meta-analysis

Aurélie Albert, Alistair G. Auffret, Eric Cosyns, Sara A. O. Cousins, Bram D'Hondt, Carsten Eichberg, Amy E. Eycott, Thilo Heinken, Maurice Hoffmann, Bogdan Jaroszewicz, Juan E. Malo, Anders Mårell, Maarten Mouissie, Robin J. Pakeman, Mélanie Picard, Jan Plue, Peter Poschlod, Sam Provoost, Kiowa Alraune Schulze & Christophe Baltzinger
Plant communities are often dispersal-limited and zoochory can be an efficient mechanism for plants to colonize new patches of potentially suitable habitat. We predicted that seed dispersal by ungulates acts as an ecological filter – which differentially affects individuals according to their characteristics and shapes species assemblages – and that the filter varies according to the dispersal mechanism (endozoochory, fur-epizoochory and hoof-epizoochory). We conducted two-step individual participant data meta-analyses of 52 studies on plant dispersal...

Data from: Auxotrophy and intra-population complementary in the 'interactome' of a cultivated freshwater model community

Sarahi L. Garcia, Moritz Buck, Katherine D. McMahon, Hans-Peter Grossart, Alexander Eiler & Falk Warnecke
Microorganisms are usually studied either in highly complex natural communities or in isolation as monoclonal model populations that we manage to grow in the laboratory. Here, we uncover the biology of some of the most common and yet-uncultured bacteria in freshwater environments using a mixed culture from Lake Grosse Fuchskuhle. From a single shotgun metagenome of a freshwater mixed culture of low complexity, we recovered four high-quality metagenome-assembled genomes (MAGs) for metabolic reconstruction. This analysis...
