Transformation of butterfly fauna on a middle scale: Situation in the South Bohemian Region.
ZAPLETAL, Michal
This thesis summarises historical and recent information on the distribution of butterflies in South Bohemian region, based on 130 records from literature, collections and recording reports, amassed during Mapping of Czech Republic butterflies. Historical and present distributions of each of 130 butterfly species found in their region are displayed on distribution maps. Out of the 130 species, 42,1 % is already extinct, while 24,1 % is threatened to some extend. Comparison with the situation in entire Czech Republic reveals a higher rate of extinctions, which is probably a function of smaller total area. Compared with the Czech Republic total, xerophilous species suffered higher losses in South Bohemia, whereas species of mesic habitats are relatively less endangered and for peat bogs specialists, the region represents a major refugium. Priorities for further research and active conservation measures are discussed.

Deposition ozone flux over a Norway spruce forest and correlation with
Zapletal, M. ; Cudlín, Pavel ; Chroust, P. ; Urban, Otmar ; Pokorný, Radek ; Edwards-Jonášová, Magda ; Czerný, Radek ; Janouš, Dalibor ; Taufarová, Klára ; Medlen, A. ; Večeřa, Zbyněk ; Mikuška, Pavel ; Skácel, F.
Measured and modelled results of ozone deposition and stomatal flux to a Norway spruce forest in locality Bílý Kříž in July and August 2008 were compared. Enhanced concentration of ozone decreased net ecosystem production, especially at higher temperatures and high intensity of global radiation.

Rodents as a forest pest species
Heroldová, Marta ; Suchomel, J. ; Zejda, J. ; Obdržálková, D. ; Zapletal, M.
Dynamic of rodents species in forest as well as in the fields was evaluated. Impact of rodent species on forest or orchard young trees was found to be in positive correlation with their density. Individual species of rodents and their foraging ecology in relationship to impact on forest regeneration was discussed. In case of common vole strong impact on orchard trees in case of high population densities and long and snowy winters was stated. Importance of long time monitoring with possibility to predict rodents gradation was stressed on.
