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: Corrections for rooting volume and plant size reveal negative effects of neighbour presence on root allocation in pea

Bin J. W. Chen, Heinjo J. During, Peter J. Vermeulen, Hans De Kroon, Hendrik Poorter & Niels P. R. Anten
Plants are able to detect the presence of their neighbours belowground. The associated root responses may affect plant performance, plant-plant interactions and community dynamics, but the extent and direction of these responses is heavily debated. Some studies suggest that plants will over-proliferate roots in response to neighbours at the expense of reproduction, which was framed as a “tragedy of the commons”. Others proposed an “ideal free distribution” hypothesis, stating that plants produce roots simply as...

Data from: Coverage of the 2011 Q fever vaccination campaign in the Netherlands, using retrospective population-based prevalence estimation of cardiovascular risk-conditions for chronic Q fever

Background: In 2011, a unique Q fever vaccination campaign targeted people at risk for chronic Q fever in the southeast of the Netherlands. General practitioners referred patients with defined cardiovascular risk-conditions (age >15 years). Prevalence rates of those risk-conditions were lacking, standing in the way of adequate planning and coverage estimation. We aimed to obtain prevalence rates retrospectively in order to estimate coverage of the Q fever vaccination campaign. Methods: With broad search terms for...

Data from: Native and non-native plants provide similar refuge to invertebrate prey, but less than artificial plants

Bart M.C. Grutters, Bart J.A. Pollux, Wilco C.E.P. Verberk, Elisabeth S. Bakker, Bart M. C. Grutters, Bart J. A. Pollux & Wilco C. E. P. Verberk
Non-native species introductions are widespread and can affect ecosystem functioning by altering the structure of food webs. Invading plants often modify habitat structure, which may affect the suitability of vegetation as refuge and could thus impact predator-prey dynamics. Yet little is known about how the replacement of native by non-native vegetation affects predator-prey dynamics. We hypothesize that plant refuge provisioning depends on (1) the plant’s native status, (2) plant structural complexity and morphology, (3) predator...

Data from: Diversity effects on root length production and loss in an experimental grassland community

Liesje Mommer, Francisco M. Padilla, Jasper Van Ruijven, Annemiek Smit-Tiekstra, Hannie De Caluwe, Frank Berendse & Hans De Kroon
Advances in root ecology have revealed that root standing biomass is higher in species-rich plant communities than in species-poor communities. Currently, we do not know whether this below-ground diversity effect is the result of enhanced root production or reduced root mortality or both, which is essential information to understand ecosystem functioning, as it determines C sequestration and N dynamics in soil. Minirhizotron observations were combined with root coring in five different plant communities (four monocultures...

Survey of British calcareous grasslands, 1990 and 2007

T.C.G. Rich, E.A. Cooper, J.S. Rodwell, A.J.C. Malloch, L.J.L. Van Den Berg, P. Vergeer, S.M. Smart, D Guest & M.R Ashmore
Vegetation species and soil data from a large national survey of calcareous grasslands, carried out in Great Britain in 1990-1993 (referred to as 1990) and 2006-2009 (referred to as 2007). Up to 128 12x12m plots were surveyed from across the country, selected on the basis of being representative of the calcareous grassland type. Details about plant species and soils were collected using standardized survey methods. The 1990 survey was completed under a contract from the...

Data from: Direct and indirect effects of nursery habitats on coral-reef fish assemblages, grazing pressure, and benthic dynamics

Alastair R. Harborne, Ivan Nagelkerken, Nicholas H. Wolff, Yves-Marie Bozec, Martijn Dorenbosch, Monique G. G. Grol & Peter J. Mumby
Migrating species are common within seascapes, but the potential for these movements to alter the populations and functional roles of non-migrating species (e.g. by increasing predation) is rarely investigated. This study considers whether the presence of nursery habitats (mangroves and seagrass) simply enhances the abundance of nursery-using parrotfishes and piscivores on nearby coral reefs, or also affects other parrotfishes. Data from 131 reef sites and multiple seascape configurations across 13 degrees of latitude were used...

Data from: Mental illness, poverty and stigma in India: a case control study

Jean-Francois Trani, Parul Bakhshi, Jill Kuhlberg, Sreelatha S. Venkataraman, Hemalatha Venkataraman, Nagendra N. Mishra, Nora E. Groce, Sushrut Jadhav & Smita Deshpande
Objective: To assess the effect of experienced stigma on depth of multidimensional poverty of persons with severe mental illness (PSMI) in Delhi, India, controlling for gender, age and caste. Design: Matching case (hospital)–control (population) study. Setting: University Hospital (cases) and National Capital Region (controls), India. Participants: A case–control study was conducted from November 2011 to June 2012. 647 cases diagnosed with schizophrenia or affective disorders were recruited and 647 individuals of same age, sex and...

Data from: Stability of phase relationships while coordinating arm reaches with whole body motion

Romy S. Bakker, Luc P. J. Selen & W. Pieter Medendorp
The human movement repertoire is characterized by the smooth coordination of several body parts, including arm movements and whole body motion. The neural control of this coordination is quite complex because the various body parts have their own kinematic and dynamic properties. Behavioral inferences about the neural solution to the coordination problem could be obtained by examining the emerging phase relationship and its stability. Here, we studied the phase relationships that characterize the coordination of...

Data from: Frontoparietal structural connectivity mediates the top-down control of neuronal synchronization associated with selective attention

Tom Rhys Marshall, Til Ole Bergmann & Ole Jensen
Neuronal synchronization reflected by oscillatory brain activity has been strongly implicated in the mechanisms supporting selective gating. We here aimed at identifying the anatomical pathways in humans supporting the top-down control of neuronal synchronization. We first collected diffusion imaging data using magnetic resonance imaging to identify the medial branch of the superior longitudinal fasciculus (SLF), a white-matter tract connecting frontal control areas to parietal regions. We then quantified the modulations in oscillatory activity using magnetoencephalography...
