Zhodnocení významu vybraných druhů skladištních škůdců v uplynulých 10 letech
Čížek, Lukáš
In thesis, I engage in the most significant storage pest, their description and division into pest with evolution inside food and outside food. My thesis describes risks and damages that may be caused by pest. It informs of characteristics of direct and undirect damages and physical, chemical and biological risks. I briefly deal with the different methods of monitoring and protection materials from storage pest. The questionnaire for the company Agrospol Knínice u Boskovic is included in my thesis. It finds out what kinds of pest are most occurred during years and what preventive measures were performed against them.

Changes of biodiversity and composition of insect communities during restoration of tropical environments
Halamová, Pavla ; Tropek, Robert (advisor) ; Čížek, Lukáš (referee)
in English Tropical rainforests are the richest habitats, but most endangered habitats on the world as well. Given the current global trend of deforestation, successful restoration of secondary forests is necessary for maintaining the rich fauna and flora of tropical rainforests. Insects are the most diverse group of animals in the tropics and they have crucial roles in an ecosystem functioning. Restoration interventions in degraded forests are nowadays more common and case studies are involving insect communities, however no review of them has been conducted. The aim of this thesis was to summarize the results of hitherto published studies dealing with the insect responses to the restoration of the tropical rainforests. With the emphasis on logged forests and lands converted for agriculture, the insect species richness, abundance, diversity, and the changes of composition were studied. If ecological conditions are suitable, insect species richness, abundance, diversity, and similarity of composition tend to increase towards primary forests for majority of insect groups. However, we observe some differences across groups of insects, based on the type and severity of disturbance, and on specific conditions on the site. Keywords: insect recovery, tropical rainforest, disturbance, species diversity,...

Methodology for management of species rich (open) forests
Čížek, Lukáš ; Šebek, Pavel ; Bače, R. ; Beneš, Jiří ; Doležal, J. ; Dvorský, M. ; Miklín, J. ; Svoboda, M.
The methodology describes the importance of open woodlands for biodiversity, the history and current state of the open woodlands in the Czech Republic, and management strategies that can be used in restoration, maintenance, and conservation of forests with open structure of the canopy. The methodology serves as general guidelines for managers on sites where open woodlands or their associated specialized species are still present.

Factors affecting the composition of insect communities on carcases of small mammals
Máslo, Petr ; Šípek, Petr (advisor) ; Čížek, Lukáš (referee)
This thesis describes invertebrate community on cadavers of small mammals, in particulat how cadaver size influences abundace, density, species richness and composition of the necrobiont community. Cadaver size preference of present insects is also described. Field experiments were performed in 2014 in meadow habitats in spring, summer and autumn season. Cadavers were chosen in three weight groups: mice (20 g), small rats (100 g) and large rats (400 - 500 g). Invertebrate abundance increases with cadaver mass, density of the community remains constant. Larger cadavers also have higher species richness. Most dominant ecological guild are necrophages, represented mosty by blow flies (Calliphoridae). Cadaver size preference of recorded insects differ, necrophagous and predatory taxa tend to prefer larger cadavers. Omnivorous carrion beetles (Silphidae: Nicrophorus) prefer small cadavers. Sex of the carrion beetles (Silphidae) does not affect their cadaver size preference, males and females of particular species have very similar preferences. Keywords Ephemeral resource patch, cadaver, necrobiont, size, abundace, diversity, competition, insect communities

Guidebook to care for populations of the Alpine Longhorn Beetle (Rosalia alpina)
Čížek, Lukáš ; Drag, Lukáš ; Hauck, David ; Foltan, P. ; Okrouhlík, J.
This guidebook to care for populations of the Alpine Longhorn Beetle (Rosalia alpina) is based on the most recent scientific information available on biology and habitat requirements of the species. It also incorporates state of art knowledge on dynamics of its habitats and management of of sites inhabited by the species, including measures such as active creation of its habitat trees. The guidebook thus delivers effective guidelines for care for populations of this „priority“ species protected by European Union. The application of active and passive management measures described within this guide will ensure survival existing populations of this highly threatened species as well as their spread to wider surroundings of currently inhabited sites.

Guidebook to care for populations of the Great Stag Beetle (Lucanus cervus)
Čížek, Lukáš ; Konvička, Ondřej ; Hauck, David ; Foltan, P. ; Okrouhlík, J.
This guidebook to care for populations of the Great Stag Beetle (Lucanus cervus) is based on the most recent scientific information available on biology and habitat requirements of the species. It also incorporates state of art knowledge on dynamics of its habitats and management of of sites inhabited by the species. The guidebook thus delivers effective guidelines for care for populations of this icon of biodiversity associated with dead wood and open woodlands. The application of active management measuresa described within the guide will ensure survival existing populations of this species.

Guidebook to care for populations of the Flat Bark Beetle (Cucujus cinnaberinus)
Čížek, Lukáš ; Hauck, David ; Konvička, Ondřej ; Foltan, P. ; Okrouhlík, J.
This guidebook to care for populations of the Flat Bark Beetle (Cucujus cinnaberinus) is based on the most recent scientific information available on biology and habitat requirements of the species. Since the beetle currently spreads in Central Europe, no specific measures are needed to support its populations at most sites. Basic rules proposed in the guide should be applied at sites designed for protections of the Flat Bark Beetle. And since the pressure on exploitation of renewable resources might soon result in decrease of dead wood availability in the region, thus leading to decline of the beetle populations. In such case, the rules presented in the guide should be applied to woodlands inhabited by the species.
