Green infrastructure has weak conceptual links with efficient biodiversity conservation.

To reverse biodiversity loss, creating resilient ecological networks has been promoted in policy and practice. However, we argue that emphasising networks within policy without clear conservation prioritisations may direct focus away from ecological processes important for population persistence. We studied the rationale for resilient ecological networks represented in a policy context, by reviewing research related to biodiversity within the concept of green infrastructure in European policy.

Pollinator-mediated effects of landscape-scale land use on grassland plant community composition and ecosystem functioning - seven hypotheses.

Environmental change is disrupting mutualisms between organisms worldwide. Reported declines in insect populations and changes in pollinator community compositions in response to land use and other environmental drivers have put the spotlight on the need to conserve pollinators. While this is often motivated by their role in supporting crop yields, the role of pollinators for reproduction and resulting taxonomic and functional assembly in wild plant communities has received less attention.

Evolutionary plant-pollinator responses to anthropogenic land-use change: impacts on ecosystem services.

Agricultural intensification at field and landscape scales, including increased use of agrochemicals and loss of semi-natural habitats, is a major driver of insect declines and other community changes. Efforts to understand and mitigate these effects have traditionally focused on ecological responses. At the same time, adaptations to pesticide use and habitat fragmentation in both insects and flowering plants show the potential for rapid evolution.

When beggars are choosers-How nesting of a solitary bee is affected by temporal dynamics of pollen plants in the landscape.

Wild bees are declining in intensively farmed regions worldwide, threatening pollination services to flowering crops and wild plants. To halt bee declines, it is essential that conservation actions are based on a mechanistic understanding of how bee species utilize landscapes. We aimed at teasing apart how foraging resources in the landscape through the nesting season affected nesting and reproduction of a solitary bee in a farmland region.

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

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 and Western Europe, overrepresenting bumblebees and raising concerns that model results may not be generalizable to other regions and taxa.

Scanning accuracy and precision in 4 intraoral scanners: an in vitro comparison based on 3-dimensional analysis.

Statement Of Problem: Intraoral scanners may use proprietary acquisition and manufacturing processes. However, limited information is available regarding their accuracy, their precision, and the influence that refraction or coating may have on their output.

Purpose: The purpose of the study was to evaluate the scanning accuracy and precision of 4 intraoral scanners and to assess the influence of different test materials and coating thicknesses.

Digitization of simulated clinical dental impressions: virtual three-dimensional analysis of exactness.

Objectives: To compare the exactness of simulated clinical impressions and stone replicas of crown preparations, using digitization and virtual three-dimensional analysis.

Methods: Three master dies (mandibular incisor, canine and molar) were prepared for full crowns, mounted in full dental arches in a plane line articulator. Eight impressions were taken using an experimental monophase vinyl polysiloxane-based material.

Computer aided analysis of digitized dental stone replicas by dental CAD/CAM technology.

Objectives: To determine the reproducibility of digitized dental stone replicas compared to the master model and the reliability of the computer aided analysis.

Methods: Four master dies, prepared for complete crowns were fabricated in presintered yttria-stabilized tetragonal zirconia (Y-TZP). Eight vinyl polysiloxane impressions (PROVIL novo; Heraeus Kulzer) were taken of each die and stone replicas were poured in type IV stone (Vel-Mix Stone; Kerr).
