Deciphering voids in Dasycladales, the case of Dragastanella transylvanica, a new Lower Cretaceous triploporellacean genus from Romania

Filippo Barattolo, Ioan Bucur & Alexandru Marian
Dragastanella transylvanica n.gen. n.sp. is described. Its calcified skeleton contains numerous voids, partly related to the moulds of soft parts of the alga, but also to lack of calcification. Interpretation of these voids, especially their attribution to original structures (e.g., primary lateral vs. reproductive organ), has important implications for the taxonomic position of the alga, even at family level. Examination of key sections that include the boundary between sterile and fertile parts of the alga...

Social groups with diverse personalities mitigate physiological stress in a songbird

Csongor I. Vágási, Attila Fülöp, Gergely Osváth, Péter Pap, Janka Pénzes, Zoltán Benkő, Ádám Lendvai & Zoltán Barta
Social groups often consist of diverse phenotypes, including personality types, and this diversity is known to affect the functioning of the group as a whole. Social selection theory proposes that group composition (i.e. social environment) also influences the performance of individual group members. However, the effect of group behavioural composition on group members remains largely unexplored, and it is still contentious whether individuals benefit more in a social environment with homogeneous or diverse behavioural composition....

Update on maxima of fine-scale vascular plant species richness in a Transylvanian steppe meadow

Jan Roleček, Pavel Dřevojan, Petra Hájková, Irina Goia & Michal Hájek
We report new maxima of vascular plant species richness ever recorded in 10-m2 plots (115 and 110 species in two adjacent plots). Both come from a steppe meadow at a well-known site Valea Lui Craiu, located in the Fânaţele Clujului grassland complex close to the city of Cluj in Transylvania, Romania, where maximum values have been observed before. We also correct the previously pub-lished maximum of 106 species, which was recorded in a 10.9-m2 plot...

Data from: Postglacial determinants of regional species pools in alpine grasslands

Aim: Alpine habitats support unique biodiversity confined to high-elevation areas in the current interglacial. Plant diversity in these habitats responds to area, environment, connectivity and isolation, yet these factors have been rarely evaluated in concert. Here we investigate major determinants of regional species pools in alpine grasslands, and the responses of their constituent species groups. Location: European mountains below 50ºN. Time Period: Between 1928 and 2019. Major Taxa Studied: Vascular plants. Methods: We compiled species...
