Assembly of the Variscan Orogenic Wedge in the Bohemian Massif: Monazite U‐Pb Geochronology of the Tectonic Events Recorded in Saxothuringian Metasediments

open access: yesTectonics, Volume 42, Issue 4, April 2023., 2023
Abstract The geochronology of metasediments incorporated to orogenic wedges provides an important key in understanding the early evolution of collisional systems. This study reveals the timing of Variscan processes in the Saxothuringian orogenic wedge, reflecting transition from oceanic to continental subduction and collision.

Larvae of longhorned beetles (Coleoptera; Cerambycidae) have evolved a diverse and phylogenetically conserved array of plant cell wall degrading enzymes

open access: yesSystematic Entomology, Volume 46, Issue 4, Page 784-797, October 2021., 2021
We addressed the numbers, kinds and evolution of cerambycid plant cell wall degrading enzymes (PCWDEs) by surveying larval midgut transcriptomes from 23 species representing six of the eight recognized subfamilies of Cerambycidae. We identified 340 new putative PCWDEs belonging to ten carbohydrate active enzyme families, including two gene families ...

Feeding patterns of red deer Cervus elaphus along an altitudinal gradient in the Bohemian Forest: effect of habitat and season

open access: yesWildlife Biology, Volume 16, Issue 2, Page 173-184, June 2010., 2010
Abstract We studied diet composition of red deer Cervus elaphus in the Bohemian Forest by micro‐histological analysis of 207 samples of red deer faeces obtained on the Czech and the Bavarian side of the border. We carried out the research from October 2006 to February 2008, and collected samples every two months at nine monitoring plots that were ...
