ReSurveyEurope: A database of resurveyed vegetation plots in Europe

Aims: We introduce ReSurveyEurope - a new data source of resurveyed vegetation plots in Europe, compiled by a collaborative network of vegetation scientists. We describe the scope of this initiative, provide an overview of currently available data, governance, data contribution rules, and accessibility. In addition, we outline further steps, including potential research questions. Results: ReSurveyEurope includes resurveyed vegetation plots from all habitats. Version 1.0 of ReSurveyEurope contains 283,135 observations (i.e., individual surveys of each plot) from 79,190 plots sampled in 449 independent resurvey projects. Of these, 62,139 (78%) are permanent plots, that is, marked in situ, or located with GPS, which allow for high spatial accuracy in resurvey. The remaining 17,051 (22%) plots are from studies in which plots from the initial survey could not be exactly relocated. Four data sets, which together account for 28,470 (36%) plots, provide only presence/absence information on plant species, while the remaining 50,720 (64%) plots contain abundance information (e.g., percentage cover or cover-abundance classes such as variants of the Braun-Blanquet scale). The oldest plots were sampled in 1911 in the Swiss Alps, while most plots were sampled between 1950 and 2020. Conclusions: ReSurveyEurope is a new resource to address a wide range of research questions on fine-scale changes in European vegetation. The initiative is devoted to an inclusive and transparent governance and data usage approach, based on slightly adapted rules of the well-established European Vegetation Archive (EVA). ReSurveyEurope data are ready for use, and proposals for analyses of the data set can be submitted at any time to the coordinators. Still, further data contributions are highly welcome.OA-hybri

Allelopathic effect of Salix caprea litter on late successional plants at different substrates of post-mining sites - pot experiment studies

The willow Salix caprea is a common colonizer of post-mining sites including those in the Sokolov coal mining district (Czech Republic) where this study was conducted. In one bioassay and two pot experiments, we investigated the effect of S. caprea litter on three plant species (Arrhenatherum elatius, Plantago lanceolata, and Lotus corniculatus) that commonly grow in late successional stages on these sites

Plant-soil interactions in succession on post-mining sites

Field observation and manipulative experiments were carried out to describe and test important processes affecting the plant succession on Sokolov post-mining sites. Examined was mainly effect of dominant tree species (which are planted or spontaneously established) on understory plants, litter decomposability and effect of earthworms (Lumbricidae) on late successional plant species

Allelopathic effect of <i>Salix caprea</i> litter on late successional plants at different substrates of post-mining sites: pot experiment studies

The willow Salix caprea L. is a common colonizer of post-mining sites including those in the Sokolov coal mining district (Czech Republic) where this study was conducted. In one bioassay and two pot experiments, we investigated the effect of S. caprea litter on three plant species ( Arrhenatherum elatius (L.) P. Beauv. ex J. Presl &amp; C. Presl, Plantago lanceolata L., and Lotus corniculatus L.) that commonly grow in late successional stages on these sites. In a sandy soil, leachate from fresh S. caprea litter reduced the number of germinated individuals (experiment 1) and shoot and root growth (experiment 2). In the clayey substrate originally unaffected by the S. caprea (experiment 3) leachate suppressed germination of all three species, but no reduction of biomass (both aboveground and belowground) was observed. Biomass was enhanced, however, in substrate that was naturally enriched with S. caprea litter (i.e., substrate collected on the same locality as previously mentioned substrate but beneath the S. caprea shrubs). Salix caprea therefore can suppress the establishment of new plants that arrive as seeds, but this suppression may only occur with seeds that directly contact the litter. When S. caprea litter is incorporated into the substrate, it can considerably improve substrate quality and the growth of successional plants. </jats:p
