Classification of the high‐rank syntaxa of the Central and Eastern Balkan dry grasslands with a new hierarchical expert system approach

open access: yesApplied Vegetation Science, Volume 27, Issue 2, April/June 2024.
We classified the dry grasslands of the Central and Eastern Balkan Peninsula with a large dataset and a new classification approach, called iterative cluster optimisation for hierarchical expert systems (ICO‐HES). We distinguish and describe 12 alliances, placed in eight orders and four classes, with one alliance and one order new to science.

Trophic level and specialization moderate effects of habitat loss and landscape diversity on cavity‐nesting bees, wasps and their parasitoids

open access: yesInsect Conservation and Diversity, Volume 17, Issue 1, Page 65-76, January 2024.
Differences in species responses with regard to their trophic level, food and habitat specialization, and to habitat loss from local to landscape scales are poorly understood. Using cavity‐nesting communities of bees, wasps and their parasitoids on calcareous grasslands as a model system, we found that species from higher trophic levels experienced ...
