Carnivores and ungulates in Mid-European landscape
Podhůrská, Marie ; Horáček, Ivan (advisor) ; Hart, Vlastimil (referee)
Carnivores and ungulates in Mid-European landscape Abstract The paper provides a brief survey of abundance status and population trends for most species of large mammals distributed in the Czech Republic. Abundance dynamics during past decades is discussed based on hunter statistic records covering both yearly data on hunting bags and standardized accounts of spring abundance of game animals from gamekeeper's evidence. It is documented that most of the species including regularly hunted ungulates, most of mesocarnivores and currently expanding species (racoon dog, racoon) are undergoing fluent population density increase contrasting with decrease of abundance of smaller to medium sized forms (hare, rabbit, marten, polecat). The respective data suggest that recently the community structure of large mammals has undergone considerable rearrangements. The monitoring of such phenomena is worth of a serious zoological research. The paper discussed methodological issues for such studies with particular attention to techniques of monitoring with aid of automated camera traps. Relations of the recorded faunal changes and landscapes rearrangements during past decades are also discussed. The paper is supplementing with a brief summary of two-year camera trap study in Brdy Mts. Key words: carnivora and ungulates,...

Floristic survey of natural monument Vinice (Příbram district)
Ambrožová, Veronika ; Česká, Jana (advisor) ; Petrů, Veronika (referee)
Floristic survey of the natural monument Vinice (district Příbram) was conducted during growing seasons in 2012 and 2015. The study area is located near Jince and it is important paleontological deposit of Cambrian fauna.
The aim of this thesis was a floristic inventory of vascular plant species, with a focus on validation of endangered and exotic species occurrence. The thesis also includes an evaluation of previous work results and current treatment interventions in context with the management plan.
In the natural monument Vinice, there were 61 vascular plant species inventoried on selected parts of the monitored area in 2015 (in 2012, there were 47 plans species determined, excluding families Poaceae, Juncaceae and Cyperaceae). Presence of two endangered species was confirmed in both years, while another three previously recorded (in year 2006) endangered species were not found at the study area in 2015.
Five alien species were recorded in 2015, of which the black locust (Robinia pseudacacia) and small balsam (Impatiens parviflora) are invasive nature. Potential threat to the locality can be common broom (Cytisus scoparius), although it is not considered as an invasive species in the Czech Republic.
On the basis of floristic inventories four main habitats were indicatively set (Hercynian oak - hornbeam forests, herb-rich beech forests, acidophilous thermophilous oak forests and dry acidophilous oak forests).
To preserve this valuable paleontological and also botanical site is recommended to follow the management plan for the period 2007-2016, where the appropriate interventions are described. The new management plan should emphasize the protection of paleontological deposits and the liquidation of alien species populations (including common broom) especially on rock terraces with thermophilic vegetation.
