Data from: Tracking population genetic signatures of local extinction with herbarium specimens

Christoph Rosche, Annnett Baasch, Karen Runge, Philipp Brade, Sabrina Träger, Christian Parisod & Isabell Hensen
Background and Aims Habitat degradation and landscape fragmentation dramatically lower population sizes of rare plant species. Decreasing population sizes may, in turn, negatively affect genetic diversity and reproductive fitness which can ultimately lead to local extinction of populations. Although such extinction vortex dynamics have been postulated in theory and modelling for decades, empirical evidence from local extinctions of plant populations is scarce. In particular, comparisons between current vs. historical genetic diversity and differentiation are lacking...

Seed traits matter—Endozoochoric dispersal through a pervasive mobile linker

Jonas Stiegler, Katrin Kiemel, Jana Eccard, Christina Fischer, Robert Hering, Sylvia Ortmann, Lea Strigl, Ralph Tiedemann, Wiebke Ullmann & Niels Blaum
Although many plants are dispersed by wind and seeds can travel long distances across unsuitable matrix areas, a large proportion relies on co-evolved zoochorous seed dispersal to connect populations in isolated habitat islands. Particularly in agricultural landscapes, where remaining habitat patches are often very small and highly isolated, mobile linkers as zoochorous seed dispersers are critical for the population dynamics of numerous plant species. However, knowledge about the quali- or quantification of such mobile link...

Pflanzengesellschaft des Jahres 2021: Hartholz-Auenwald (Ficario-Ulmetum)

Werner Härdtle, Erwin Bergmeier, Andreas Fichtner, Thilo Heinken, Norbert Hölzel, Dominique Remy, Simone Schneider, Angelika Schwabe, Sabine Tischew & Hartmut Dierschke
Hardwood floodplain forests (Ficario-Ulmetum, Syn.: Querco-Ulmetum), being amongst the most endangered plant communities in Germany, have been selected as ‘Plant community of the year 2021’ by the Floristisch-soziologische Arbeitsgemeinschaft. Hardwood floodplain forests are temperate low-land broad-leaved forest ecosystems typical of extensive river valleys. In Central Europe, stands represent biodiversity hotspots for woody species (as habitats for rare tree species such as Ulmus laevis and Populus nigra), but also host numerous fungi and animal species typical...

Ackerwildkraut-Vegetation der Kalkäcker (Caucalidion): Pflanzengesellschaft des Jahres 2022

Erwin Bergmeier, Stefan Meyer, Fionn Pape, Hartmut Dierschke, Werner Härdtle, Thilo Heinken, Norbert Hölzel, Dominique Remy, Angelika Schwabe, Sabine Tischew & Simone Schneider
Als Pflanzengesellschaft des Jahres 2022 ist die Ackerwildkraut-Vegetation der Kalkäcker, der Ver- band Caucalidion, ausgewählt worden. In diesem Übersichtsartikel stellen wir den Verband vor und betrachten dabei seine Artenzusammensetzung und -diversität, Verbreitung, standörtliche und pflanzen- soziologische Variabilität, das Ökosystem „Kalkacker”, die früher und heute wirksamen Faktoren des Ackerbaus und die Ursachen des massiven Rückgangs in den letzten Jahrzehnten. Schließlich beleuch- ten wir Optionen zur Erhaltung und Wiederherstellung artenreicher Caucalidion-Vegetation und der von ihnen abhängigen Lebensgemeinschaften....
