This article provides brief information on the history and prominent botanists exploring the surroundings of Prague. it is dedicated to V. Skalický, who intensively studied Prague flora in the second half of the 20th century. Two new sites of C. rivulare and C. heterophyllum in Prague are described. While the occurrence of C. rivulare can be found in numerous and vital populations in the Šárecký potok valley. and Jiří Hadinec.
Understanding the history of coniferous forests and their natural changes over time is critical for proper and effective forest management. The text describes the origin and disturbance history of the mountain Norway Spruce (Picea abies) forests in the Šumava Mts. (Bohemian Forest) using tree-ring and archival documents analyses. Severe and extensive natural disturbances play and have played a fundamental role in forest structure and dynamics. Part of the territory has been shaped by forest management. and Vojtěch Čada ...

Research by the Masaryk University in Siberia is focused on ecosystems similar to Central European palaeoecosystems of the Pleistocene and Early Holocene. We mainly deal with the diversity and productivity of plant communities and their relationships to indicators of past environments (pollen deposition, mollusc assemblages). The results indicate that the best analogues of Pleistocene ecosystems are found in the Altai-Sayan region of southern Siberia. and Milan Chytrý.
Článek přináší poznatky o vznikajících mezidruhových vztazích v ekosystémech po zavlečení nového invazního druhu rostliny – netýkavky žláznaté (Impatiens glandulifera) – a uvádí některé entomologické aspekty jejího masového výskytu v novém prostředí., The impact of aphids on the invasive plant Impatiens glandulifera in the Czech Republic is shown and some entomological aspects of I. glandulifera distribution in local ecosystems are discussed., and Petr Starý, Jan Havelka.
Wetlands on arable land host ephemeral vegetation and their existence relies on soil water saturation and periodic mechanical disturbations. In this habitat, we found several rare species listed in the Black and Red List of Vascular Plants of the Czech Re - public. Evidently, wetlands on arable land deserve protection and further research is needed for their closer inspection. and Radomír Němec, Vlasta Škorpíková, Václav Křivan.
