Detection and variation of the crayfish plague pathogen in selected crayfish populations
Mojžišová, Michaela ; Petrusek, Adam (advisor) ; Buřič, Miloš (referee)
Crayfish plague is an emerging disease caused by the oomycete Aphanomyces astaci, a pathogen listed among the 100 World's Worst Invasive Alien Species. It was introduced into Europe in the second half of 19th century from North America and caused collapses of European native crayfish populations. Nowadays, A. astaci is widespread in Europe and has spread also to other parts of the world, threatening all susceptible crayfish of non-North American origin. The aims of this MSc thesis were 1) to provide information about crayfish plague outbreaks from recent years, and by using microsatellite and mtDNA markers reveal A. astaci genotypes involved; 2) to test healthy-looking indigenous crayfish for potential occurrence of chronic infections by A. astaci in Czechia. Six new crayfish plague outbreaks were confirmed from 2016 to 2018, involving at least five distinct pathogen strains. My results provide first evidence of the A. astaci genotype group D causing Astacus astacus and Austropotamobius torrentium mass mortalities in Czechia. MtDNA sequencing revealed two haplotypes of the D haplogroup, indicating two independent sources of infection presumably either from ornamental crayfish or spreading from neighbouring countries. The genotype group A was recorded in two A. astacus mortalities and genotype group...

Year with animals in kindergarten Čechtice
MOJŽÍŠOVÁ, Michaela
This bachelor thesis leads to establishing of yearlong project for children from kindergarten in Čechtice, in which there are introduced selected animals species living in the neighbourhood of kindergarten in Čechtice to children. The aim of this thesis is both introduce animals to children and especially establish positive relationship to living creatures and to nature all around them. This work contains theoretical and practical part. The theoretical part is focused on problematics of including animals to kindergartens education and its appropriateness both according to various criteria regarding to needs and capabilities of preschool children and in compliance with Framewok Education Programme for preschool education. In addition it includes information about key animal species. There is described yearlong project in the practical part, which is bound with the class mascot centipede Jůlie and focused on integrated education of children. There are also characteristics of each selected animal with descriptions of activities and reflection.

Revenue assurance methodology
Mojžíšová, Michaela ; Dvořáček, Jiří (advisor) ; Hnilica, Jiří (referee) ; Novotná, Markéta (referee)
Práce se zabývá návrhem uceleného teoreticko-metodologického rámce nové podnikové funkce revenue assurance pro telekomunikační společnosti, které usilují o systematický a koncepční přístup k zajištění a maximalizaci příjmů. Popsány jsou role revenue assurance funkce v podniku, cíle, vývojová stádia. Dále jsou popsány hrozby a konkrétní podoby úniků a nadhodnocení příjmů. Podrobně je rozebrána metodika pro plnění úkolů revenue assurance a techniky pro eliminaci úniků a nadhodnocení příjmů. Práce obsahuje také výsledky empirického průzkumu funkce revenue assurance mezi telekomunikačními společnostmi v roce 2003 a 2004.
