The importance of various habitats for fish in reservoirs
Šmejkal, Marek ; Prchalová, Marie (advisor) ; Vašek, Mojmír (referee)
Fish distribution in reservoirs is not homogeneous. Fish usually occur in upper parts of reservoirs on the longitudinal axis, where is also the greatest concentration of nutrients. Fish abundance and biomass as well as the trophy are declining towards the dam part. On the vertical axis, most fish occur above the thermocline, where temperature and concentration of dissolved oxygen reach the highest values. Fish community is changing also in time. Shortly after impoundment, the riverine species are dominating the community and later, generalist species prevail. Generally, we can distinguish pelagic and bentic habitats within the reservoir. There are species in reservoirs that occur almost strictly in pelagic habitat like asp and bleak and benthic species like ruffe and perch. Most species occur in both types of habitats (bream, roach, pikeperch, European catfish, white bream). Migrations between habitats occur on daily and on seasonal basis. On daily basis, we distinguish diel horizontal migration, in which fish shift between pelagic and benthic habitats. Diel vertical migration, when fish change depths, is not so significant in Czech reservoirs. Motivations for these diel migrations are food aviability, predation pressure and water temperature. Seasonal migrations comprise spawning migrations and winter...
Company culture and communication in construction engineering
Kuxová, Hana ; Smejkal, Marek (referee) ; Linkeschová, Dana (advisor)
The aim of this thesis is to define the corporate culture and communication in construction companies. The thesis contains definition of both terms. Evaluation of corporate cultures and communication in individual companies will be based on a quantitative questionnaire survey. Individual questions will have their own comments and at the end I will evaluate which of the cooperating companies has the best corporate culture and communication. I will also provide recommendations for possible changes. The cooperating companies are: DELTA Projektconsult, s.r.o .; KOMFORT, a.s .; OHL ŽS, a.s. The aim of the thesis is to theoretically define the topic of the importance of corporate culture and communication in the construction industry. In the practical part, then carry out a research investigation, analyze its results and assess their practical application in the construction area.
Ichthyological survey of the asp spawning stock in the Švihov Reservoir in 2018
Šmejkal, Marek ; Bartoň, Daniel ; Blabolil, Petr ; Kolařík, Tomáš ; Soukalová, Kateřina ; Děd, Vilém ; Šmejkalová, Z. ; Kočvara, Luboš ; de Moraes, Karlos Ribeiro ; Kortan, D. ; Duras, J. ; Kubečka, Jan
The aim of the study was to evaluate the results of the asp population development in relation to the current fishery management and to develop proposals for the management of this predatory species in the future.
