Abstract Mitigating the effects of global change on biodiversity requires its understanding in the past. The main proxy of plant diversity, fossil pollen record, has a complex relationship to surrounding vegetation and unknown spatial scale. We explo

Abstract One promising area in understanding the responses of plants to ongoing global climate change is the adaptative effect of polyploidy. This work examines whether there is a coupling between the distribution of cytotypes and their biogeographic

Here I report the first find of Ophrys insectifera in Ukraine since 1920. A single individual was found at its last recorded site, Chortova Hora near Rohatyn (Ivano-Frankivsk Region). The species occurs in a steppe meadow habitat situated in the lowe

Aim Pollen has been used before to reconstruct Holocene plant diversity changes in broadly delimited regions such as continents and countries. In this study we ask whether finer-scale differences in plant diversity, which are of interest to biogeogra

The extreme species richness of some temperate grasslands is a globally relevant yet understudied phenomenon. Until now, few records from thoroughly sampled, though not permanently fixed, vegetation plots were available. We therefore established a ne

Oak-hornbeam forests (order Carpinetalia) are a widespread vegetation type in central Europe. As vegetation ecologists focused on them since the pioneering times of vegetation research, many syntaxonomic units are described. However, classification s

Aims: Western Podolia is one of several regions in the Eurasian forest-steppe zone where diverse steppe vegetation has been relatively well preserved. Our aims were to describe compositional turnover of steppe vegetation along different environmental

Here we report the first find of a rare grass Festuca amethystina L. in the Transylvanian Basin. The species was found at Dealul Furcilor, a hill that is part of SCI Movilele de la Paucea near the city of Medias, in tall-forb vegetation classified as
