Population biology and evolutionary genetics of southern right whale (Eubalaena australis)
Nevečeřalová, Petra ; Hulva, Pavel (advisor) ; Galov, Ana (referee) ; Robovský, Jan (referee)
Southern right whale (Eubalaena australis) is a species from the Balaenidae family with a range in the southern hemisphere, which evolved in connection with Neogene climate oscillations. Its population biology involves migration between coastal waters of South America, southern Africa, Australia and New Zealand to its high-latitude foraging and feeding grounds in the Southern Ocean. Intensive historical hunting from the 18th to 19th century has impacted the population dynamics of baleen whales substantially. After the whaling moratorium, the species has been recovering from the heavy exploitation, however, recently it is facing anthropogenic changes, such as climate change. The South African population, considered to be the largest one globally and intensively studied for the last several decades, is showing an increase in the calving interval, a decline in female condition and a dramatic shift in migration routes since 2010, possibly as a consequence of significant changes in marine food webs. Methods of molecular ecology were applied to monitor the population genetics and its dynamics not only in the context of the global population but also to compare different time periods - 1990s and 2010s. The majority of the samples were collected noninvasively in cooperation with commercial whale-watching...

The effects of ageing on working age populations that developed and developing countries face: study case of Czech republic and the United Mexican States
Aldama Gonzalez, Hector Santiago
Ageing has always been part of human life; for the first time in history elderly people will soon become the largest group in most societies around the world. This research focuses on highlighting the challenges that developed and developing countries face with the aging of the population. The theoretical part is directed to the understanding of the aging of the population as well as its implication among developed and developing countries. The practical part focuses on a comparison of the aging of the population in the Czech Republic and the United Mexican States through an analysis of quantitative data over the performance of the labor force and general population of Czechia and Mexico with indicators obtained from government institutions specialized in the compilation of population censuses of the last 20 years. The emphasis of this work is to focus on understanding the effects that aging has over society. Unless mechanism such as the creation of new public policies, a positive net migration balance and stable fertility rates are taken to solve the effects of the ageing of the population, the aging of the population will reduce the working age population in the Czech Republic and in the United Mexican States.
Sociodemografická analýza Uzbekistánu
Abdukakhkhorova, Dilafruz
The diploma thesis deals with the socio-demographic analysis of Uzbekistan in the years 1991-2021. This work follows the development of indicators related to the number of inhabitants, mortality, birth rate and fertility, marriage, divorce rate and migration. The aim of the work is to identify problems associated with labor migration and propose possible solutions based on socio-demographic analysis. The development of individual indicators is evaluated with regard to the main causes and the overall development of Uzbekistan. A cluster analysis was used for a multi-criteria view of the selected indicators, which enabled a continuous view of the monitored country through the given indicators. The conclusion of the work consists of a summary of the most important findings and a proposal of recommendations that could improve the situation in the monitored country.
Studium prevalence a subtypové diverzity střevního prvoka rodu Blastocystis sp. ve zdravé lidské populaci v České republice
BROŽOVÁ, Kristýna
Blastocystis sp. is a common intestinal protist colonizing the human intestine. Its role in the human gut ecosystem remains unclear. Here, we aimed to expand the knowledge of the epidemiology of Blastocystis sp. in the gut-healthy humans in the Czech Republic, including the distribution of its subtypes, the correlation between its occurrence and several factors such as lifestyle, contact with animals, age, and sex. A total of 288 stool samples were obtained from asymptomatic individuals over the entire age-range and 136 samples from animals with which the volunteers were in frequent contact. All samples were examined in parallel by PCR and xenic in vitro culture.

Integration of Migrants into the Czech Society
Pokorný, Martin ; Havlík, Radomír (advisor) ; Kubišová, Zuzana (referee)
The aim of my diploma work is to study the subject of integration of foreigners into the Czech society. For that purpose I intend to use research questionnaires and to compare my results with results of other researches conducted by NGOs. Secondary aim is to map legal status of foreigners in the Czech Republic, historical reasons for migration and its development, and the composition of migrating population in Europe. Furthermore, I will focus on access to health and social insurance and to the health care system as well as on education and work opportunities which foreigners have in the Czech Republic.
