The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project

Lawrence N. Hudson, Tim Newbold, Sara Contu, Samantha L. L. Hill et autres

The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land …

Predicting bee community responses to land-use changes: Effects of geographic and taxonomic biases

Adriana De Palma, Stefan Abrahamczyk, Marcelo A. Aizen, Matthias Albrecht et autres

Land-use change and intensification threaten bee populations worldwide, imperilling pollination services. Global models are needed to better characterise, project, and mitigate bees' responses to these human impacts. The available data are, however, geographically and taxonomically unrepresentative; most data are from North America …

Correction: Corrigendum: Delivery of crop pollination services is an insufficient argument for wild pollinator conservation

David Kleijn, Rachael Winfree, Ígnasi Bartomeus, Luísa G. Carvalheiro et autres

Nature Communications 6: Article number: 7414 (2015); Published: 16 June 2015; Updated: 18 February 2016. The authors inadvertently omitted Kimiora L. Ward, who managed and contributed data, from the author list. This has now been corrected in both the PDF and HTML …

Delivery of crop pollination services is an insufficient argument for wild pollinator conservation

David Kleijn, Rachael Winfree, Ígnasi Bartomeus, Luísa G. Carvalheiro et autres

There is compelling evidence that more diverse ecosystems deliver greater benefits to people, and these ecosystem services have become a key argument for biodiversity conservation. However, it is unclear how much biodiversity is needed to deliver ecosystem services in a cost-effective way. …

PREDICTS: site-level summary biodiversity and pressure data

Lawrence N. Hudson, Tim Newbold, Sara Contu, Samantha L. L. Hill et autres

This dataset contains site-level summaries of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The …

The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts

Lawrence N. Hudson, Tim Newbold, Sara Contu, Samantha L. L. Hill et autres

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets …

De rol van ouders in het stopproces van jeugdige veelpleger

L. Volkert, Jort Verhulst

Achtergrond Onderzoek toont aan dat jeugdige veelplegers (JVP’s) vaak afkomstig zijn uit problematische gezinnen. Onderzoeksvragen In dit onderzoek wordt allereerst gekeken of stoppers afkomstig zijn uit de minst problematische gezinnen. Daarnaast wordt onderzocht of ouders door het aanpassen van negatieve opvoedingsfactoren, of …

Interactive effects of landscape context constrain the effectiveness of local agri‐environmental management

Elena D. Concepción, Mario Dı́az, David Kleijn, Andràs Báldí et autres

Summary 1. Ecological theory predicts that the effectiveness of local agri‐environmental management to enhance species richness at field scales will be the highest at intermediate levels of landscape complexity because of nonlinear effects of landscape context on field‐scale diversity. 2. We examined …

Long‐term changes in plant diversity of grasslands under agricultural and conservation management

G.R. de Snoo, Nick Naus, Jort Verhulst, Jasper van Ruijven et autres

Abstract Question In many industrialized countries biodiversity is declining. Although changes in species composition and species richness have been documented for many individual systems, little long‐term research has been done on a regional scale. We compared the temporal patterns of plant diversity …

Flip angle optimization for dynamic contrast-enhanced MRI-studies with spoiled gradient echo pulse sequences

Dieter De Naeyer, Jort Verhulst, Wim Ceelen, Patrick Segers et autres

Spoiled gradient echo pulse (SPGRE) sequences are commonly used in dynamic contrast-enhanced MRI (DCE-MRI) studies to measure the contrast agent concentration in a tissue of interest over time. However, due to improper tuning of the SPGRE parameters, concentration uncertainty can be very …
