Document Delivery and Resource Sharing: Global Perspectives

This publication is intended to provide librarians, library practitioners, as well as teachers, researchers, and students of universities and research organizations and other interested parties, a foundation in resource sharing principles, practices and management. This publication provides an overview of where things stand today with resource sharing, including key trends, challenges, opportunities, and priorities. The publication seeks to address international resource sharing, exploring the current state of European and international resource sharing systems and the governing laws and regulations and includes case studies and best practices from various countries

Document Delivery and Resource Sharing

Cette publication a été réalisée dans le cadre du projet HERMES, qui vise à fournir aux établissements d’enseignement un accès de haute qualité, rapide et gratuit à la connaissance. La capacité à mettre en œuvre et à partager une vision globale et des compétences étendues sur le partage des ressources accompagné d’un système open source pour favoriser un accès efficace à la connaissances pour tous est ainsi visé

Benchmarking plant diversity of Palaearctic grasslands and other open habitats

Abstract Aims: Understanding fine-grain diversity patterns across large spatial extents is fundamental for macroecological research and biodiversity conservation. Using the GrassPlot database, we provide benchmarks of fine-grain richness values of Palaearctic open habitats for vascular plants, bryophytes, lichens and complete vegetation (i.e., the sum of the former three groups). Location: Palaearctic biogeographic realm. Methods: We used 126,524 plots of eight standard grain sizes from the GrassPlot database: 0.0001, 0.001, 0.01, 0.1, 1, 10, 100 and 1,000 m² and calculated the mean richness and standard deviations, as well as maximum, minimum, median, and first and third quartiles for each combination of grain size, taxonomic group, biome, region, vegetation type and phytosociological class. Results: Patterns of plant diversity in vegetation types and biomes differ across grain sizes and taxonomic groups. Overall, secondary (mostly semi-natural) grasslands and natural grasslands are the richest vegetation type. The open-access file ”GrassPlot Diversity Benchmarks” and the web tool “GrassPlot Diversity Explorer” are now available online (https://edgg.org/databases/GrasslandDiversityExplorer) and provide more insights into species richness patterns in the Palaearctic open habitats. Conclusions: The GrassPlot Diversity Benchmarks provide high-quality data on species richness in open habitat types across the Palaearctic. These benchmark data can be used in vegetation ecology, macroecology, biodiversity conservation and data quality checking. While the amount of data in the underlying GrassPlot database and their spatial coverage are smaller than in other extensive vegetation-plot databases, species recordings in GrassPlot are on average more complete, making it a valuable complementary data source in macroecology
