Adaptability and Phenotype Plasticity of Invasive Parrots in Europe
 Nový, Jakub ; Figura, Roman (advisor) ; Makal, Jakub (referee)
The diploma thesis on Adaptability and Phenotypic Plasticity of Invasive Parrots in Europe deals with the analysis of a recent phenomenon, which is the emergence of non-native parrot populations in European cities. Until now, this issue has been studied mainly from the perspective of the fight against invasive species. So far much less is known about the ecological and ethological characteristics of these populations. Although most of the large non-indigenous populations are located in the territory of southern or northern Europe, this work also examined the observation and semi-wild population of parrots located in the Czech Republic. Research into phenotypic plasticity and overall adaptability of invasive species is also discussed here. The work includes hypotheses and theories related to the invasion process, including predictions of the future development of non-native populations.

Phenotypic plasticity of smooth muscle cells
 Misárková, Eliška ; Zicha, Josef (advisor) ; Pácha, Jiří (referee)
Vascular smooth muscle cells display a certain level of phenotype plasticity. Under specific conditions fully differentiated cells are able to undergo dedifferentiation and to restart growth and proliferation. An organ culture method is a useful technique for the analysis of dedifferentiation of vascular smooth muscle cells, because it provides an opportunity for studying the changes in cell phenotype. The aim of this study was to investigate the basic contractile characteristics in rat femoral arteries cultured for different time periods (from one to three days). In addition, the effects of fetal bovine serum (FBS), that contains various growth factors and other biological active molecules, on contractile function were studied. We also tried to attenuate cell dedifferentiation by lowering the calcium influx, because calcium is an important second messenger participating in cell growth and proliferation. To achieve this goal we used cultivation with nifedipine, a voltage-dependent calcium channel inhibitor. The cultivation without FBS slightly decreased arterial contractility, whereas the cultivation with FBS decreased arterial contractility considerably. The major change in contractility of arteries cultivated with FBS occurred approximately within 24 hours of cultivation. The cultivation with...
