Aim: Biodiversity hot-spots are regions containing evolutionary heritage from ancient or recent geological epochs, i.e. evolutionary 'museums' or 'cradles', respectively. We hypothesize that: (1) there are also 'museums' and 'cradles' within regions - some species pools of particular habitat types contain angiosperm (flowering plants) lineages from ancient geological epochs, others from recent epochs; (2) habitat-specific abiotic factors control the number of angiosperm lineages from a given epoch contained in a given habitat species pool. Location: The flora of the Netherlands. Methods: We studied the world's largest vegetation-plot database and a new, uniquely resolved dated angiosperm phylogeny available for the Netherlands. We characterized species pools of habitat types by a novel concept: epoch-specific lineage diversities. Results: We found that species pools of most habitat types were characterized by over- or underrepresentation of lineages from at least one epoch, dating back to the origin of angiosperms. These patterns are not captured by mean lineage ages. Abiotic environments explained on average 56% and up to 75% of the variance in the number of lineages per epoch, but with opposing effects of the same factor for different epochs. Specifically, warm and dry habitats tend to contain lineages dating back to warm and dry epochs. Identifying lineages from sets of random time intervals rather than from a set of geological epochs significantly reduced relationships with the environment. Main conclusions: Within a region, habitat types differ significantly in the evolutionary heritage they contain from different geological epochs, and these differences are controlled by the environment.

Plantengemeenschappen spelen bij veel ecosysteemfuncties en -diensten een cruciale rol. De bijdrage van plantensoorten hangt af van functionele eigenschappen als het aanbod van nectar en stuifmeel in bloemen. Lokale plantengemeenschappen verschillen sterk in het spectrum aan eigenschappen van de soorten en inzicht in deze variatie kan helpen bij duurzaam beheer en gebruik van deze functionele diversiteit. Stilgestaan wordt bij factoren die de variatie in het aanbod van nectar en stuifmeel in graslanden beïnvloeden.

In dit rapport wordt beschreven hoe in 2007 de rapportage aan de Europese Commissie in het kader van de Habittarichtlijn zal worden uitgevoerd voor habitattypen. Het betreft de eerste keer dat de Europese lidstaten over de staat van instandhouding van habitattypen rapporteren (de zogenaamde nulmeting). De vereisten van de Europese rapportage en de methoden en bronnen die gebruikt worden door Nederland, worden toegelicht.

In August 1991 Bupleurum falcatum was found on the Sint Pietersberg near Maastricht in the Dutch province of Limburg; it is likely that the establishment of Bupleurum falcatum here is spontaneous, as can be concluded from the distribution pattern of this species in the surrounding countries, as well as from the habitat of this locality (chalk grassland). Apart from a population in a so-called ‘orchid garden’, where it was (unintentionally) planted out together with the orchids, this species was considered not occurring in the Netherlands. By checking the plant collection of the Rijksherbarium in Leiden, however, it appeared that a specimen of Bupleurum falcatum was present, collected by J. Bloeme in 1965 from a locality at the eastern slope of the Jeker river near Chateau Neercanne; only a few hundred meters from the new site.

This is a dataset of Ellenberg-type indicator values for European vascular plant species described in this article: Tichý L., Axmanová I., Dengler J., Guarino R., Jansen F., Midolo G., Nobis M.P., Van Meerbeek K., Aćić S., Attorre F., Bergmeier E., Biurrun I., Bonari G., Bruelheide H., Campos J.A., Čarni A., Chiarucci A., Ćuk M., Ćušterevska M., Didukh Y., Dítě D., Dítě Z., Dziuba T., Fanelli G., Fernández-Pascual E., Garbolino E., Gavilán R.G., Gégout J.-C., Graf U., Güler B., Hájek M., Hennekens S.M., Jandt U., Jašková A., Jiménez-Alfaro B., Julve P., Kambach S., Karger D.N., Karrer G., Kavgacı A., Knollová I., Kuzemko A., Küzmič F., Landucci F., Lengyel A., Lenoir J., Marcenò C., Moeslund J.E., Novák P., Pérez-Haase A., Peterka T., Pielech R., Pignatti A., Rašomavičius V., Rūsiņa S., Saatkamp A., Šilc U., Škvorc Ž., Theurillat J.-P., Wohlgemuth T. & Chytrý M. (2023) Ellenberg-type indicator values for European vascular plant species. Journal of Vegetation Science, 34, e13168. https://doi.org/10.1111/jvs.13168 The dataset contains: 1) Harmonized Ellenberg-type indicator values for light, temperature, moisture, reaction, nutrients, and salinity for European vascular plants. 2) Original indicator values from 13 datasets of Ellenberg-type indicator values: - Germany (Ellenberg & Leuschner 2010) - Austria (Karrer 1992) - Cantabrian Range (Jiménez-Alfaro et al. 2021) - Czech Republic (Chytrý et al. 2018) - European mires (Hájek et al. 2020) - France (Julve 2015) - Great Britain (Hill et al. 2000) - Greece (South Aegean) (Böhling et al. 2002) - Hungary (Borhidi 1995) - Italy (Guarino & La Rosa 2019, modified) - Saline habitats (Dítě et al. 2023) - Switzerland and the Alps (Landolt et al. 2010) - Ukraine (Didukh 2011) 3) Species nomenclature is standardized according to the Euro+Med PlantBase (http://europlusmed.org)., The final version of the paper (accepted 8th Dec 2022; published 22nd Dec 2022). Difference from version 1.0: Minor changes in newly added species values calculated from co-occurrence with other species in the EVA database. They were corrected using straight-line calibration.
