Data from: Parasitoid wasps indirectly suppress seed production by stimulating consumption rates of their seed-feeding hosts

Xinqiang Xi, Nico Eisenhauer & Sun Shucun
1. In parasitoid–herbivore–plant food chains, parasitoids may be simultaneously linked with both herbivore hosts and plants, as occurs when herbivores attacked by parasitoids continue to consume plants although they are destined to die. This peculiar property may cause parasitoids to confer a differential trophic cascading effect on plants than that known for typical predators. 2. We hypothesized that larval koinobiont parasitoids would confer an immediate negative effect on plant seed production by stimulating consumption of...

Data from: Globally, functional traits are weak predictors of juvenile tree growth, and we do not know why

1. Plant functional traits, in particular specific leaf area (SLA), wood density and seed mass, are often good predictors of individual tree growth rates within communities. Individuals and species with high SLA, low wood density and small seeds tend to have faster growth rates. 2. If community-level relationships between traits and growth have general predictive value, then similar relationships should also be observed in analyses that integrate across taxa, biogeographic regions and environments. Such global...

Data from: Cascading effects of belowground predators on plant communities are density-dependent

Madhav Prakash Thakur, Martina Herrmann, Katja Steinauer, Saskia Rennoch, Simone Cesarz & Nico Eisenhauer
Soil food webs comprise a multitude of trophic interactions that can affect the composition and productivity of plant communities. Belowground predators feeding on microbial grazers like Collembola could decelerate nutrient mineralization by reducing microbial turnover in the soil, which in turn could negatively influence plant growth. However, empirical evidences for the ecological significance of belowground predators on nutrient cycling and plant communities are scarce. Here, we manipulated predator density (Hypoaspis aculeifer: predatory mite) with equal...

Data from: Individual behaviour mediates effects of warming on movement across a fragmented landscape

Andrew D. Barnes, Ina-Kathrin Spey, Lena Rohde, Ulrich Brose & Anthony I. Dell
Global warming and habitat fragmentation impose dramatic and potentially interactive impacts on ecosystems. Warming induces shifts in species' distributions as they track temperature changes, but this can be hindered in fragmented landscapes. Corridors connecting habitat patches might ameliorate the combined effects of fragmentation and global warming. Using novel automated tracking methods, the movement of woodlice (Oniscus asellus) ranging in body size from 15·3 to 108·6 mg was quantified across a temperature range from 15 to...

Data from: Disturbance alters beta-diversity but not the relative importance of community assembly mechanisms

Jonathan A. Myers, Jonathan M. Chase, Raelene M. Crandall & Iván Jiménez
1.Ecological disturbances are often hypothesized to alter community assembly processes that influence variation in community composition (β-diversity). Disturbance can cause convergence in community composition (low β-diversity) by increasing niche selection of disturbance-tolerant species. Alternatively, disturbance can cause divergence in community composition (high β-diversity) by increasing habitat filtering across environmental gradients. However, because disturbance may also influence β-diversity through random sampling effects owing to changes in the number of individuals in local communities (community size) or...

Data from: Genetic differentiation within multiple common grassland plants supports seed transfer zones for ecological restoration

Walter Durka, Stefan G. Michalski, Kenneth W. Berendzen, Oliver Bossdorf, Anna Bucharova, Julia-Maria Hermann, Norbert Hölzel & Johannes Kollmann
Ecological restoration of grasslands is increasingly based on regional seeds derived from predefined seed transfer zones. However, the degree and spatial pattern of genetic differentiation among provenances of different seed transfer zones is largely unknown. We assessed the genetic differentiation among eight out of 22 German seed transfer zones for seven common grassland species (Arrhenatherum elatius, Centaurea jacea, Daucus carota, Galium album, Hypochaeris radicata, Knautia arvensis and Lychnis flos-cuculi) using AFLP markers. We analysed genetic...

Data from: Ecologically diverse and distinct neighbourhoods trigger persistent phenotypic consequences, and amine metabolic profiling detects them

Françoise Hennion, Isabelle Litrico, Igor Bartish, Alexandra Weigelt, Alain Bouchereau & Andreas Prinzing
1.Global change triggers rapid alterations in the composition and diversity of plant communities which may change ecosystem functioning. Do changes in community diversity also change traits persistently, i.e. does coexistence with numerous or functionally or phylogenetically distinct species trigger, in a given focal species, trait shifts that persist? 2.We studied the grass Dactylis glomerata. Dactylis was grown in experimental plots with different species compositions for five years, sampled, cloned and grown in a common garden....
