<scp>ReSurveyEurope</scp>: A database of resurveyed vegetation plots in Europe

AbstractAimsWe 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.ResultsReSurveyEurope 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.ConclusionsReSurveyEurope 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.</jats:sec

Gorham-Stout Disease Presenting as Acute Unilateral Proptosis

Gorham-Stout disease (GSD) is a rare angiomatous disorder characterized by osteolysis. We report the case of a 66-year-old woman who developed sudden left eye proptosis and facial pain. Neuroimaging demonstrated a destructive mass involving the roof and lateral wall of the left orbit with adjacent abnormal orbital soft tissue. An initial biopsy of the soft tissue was nondiagnostic; however, transcranial biopsy of the orbital roof revealed an intraosseous cavernous angioma, with infiltration of orbital fat by angiomatous tissue. Despite resection of the orbital roof and lateral wall, the orbital lesion continued to expand, leading to signs of a compressive optic neuropathy. The patient then reported severe back pain, prompting imaging that demonstrated disseminated bony involvement of the axial skeleton, eventually leading to the diagnosis of GSD. The patient was treated with a bisphosphonate and a vascular endothelial growth factor inhibitor with stabilization of disease
