Ecologically sustainable retention forestry supports spider biodiversity in the Lower Morava UNESCO Biosphere Reserve

open access: yesInsect Conservation and Diversity, Volume 17, Issue 6, Page 1001-1015, November 2024.
Natural and commercial forests had comparable alpha‐ and beta‐diversity of ground‐dwelling spiders in the pre‐harvest year. Dispersed retention exhibited higher alpha‐ and beta‐diversity of ground‐dwelling spiders compared with clear‐cuts. Dispersed retention hosted species typical of both forests and (semi‐) open habitats, including threatened species,

Numerical Modeling of Potential Large Wood Entrainment in Rivers: Application of Hybrid Modeling in the Inter‐Dam Reach of the Dyje River, Czechia

open access: yesWater Resources Research, Volume 60, Issue 4, April 2024.
Abstract Mobilization of large wood in river channels during floods represents a hazardous factor, augmenting flood risk and endangering infrastructures such as bridges, weirs, and reservoir dams. A hybrid modeling approach combining numerical models with field‐based surveys has been recently used to elucidate the processes of LW entrainment and ...
