Evolution of litter size in hystricomorph rodents
Cingelová, Alexandra ; Dušek, Adam (advisor) ; Špoutil, František (referee)
The suborder Hystricomorpha is an ideal model group for the study of rodent life-history evolution due to its wide distribution, great diversity of inhabited ecosystems and social systems. By tracking several factors, it was possible to determine the key factors that influenced litter size during evolution. The data set contained 75 of the total 292 species of the suborder. The average litter size, female and male body size, level of sexual dimorphism, level of sociality, type of reproductive system, level of parental care, presence of multipaternity, type of habitat and food were assigned to each species based on the information obtained from the available literature. The analysis included a statistical part calculated using general linear mixed models, and a phylogenetic part including parsimonious mapping of characters onto the phylogenetic tree and linear regression using phylogenetic independent contrasts. Social factors like degree of sociality, sexual dimorphism and reproductive system significantly influenced litter size at birth. Multipaternity also had an influence, but less than the first three factors. Ecological factors, food and environment, had no effects unless they were combined with the effect of family. It is therefore possible to assume that ecological factors have influenced...

Activating Practises in Nursing Homes for Elderly People
MAŠKOVÁ, Zdeňka
This Bachelor Thesis focuses on activating practices in nursing homes for elderly people. The aim of the Thesis is to map all aspects of providing this activation. Chapter 1 characterizes old age and the ageing process and describes the changes occurring in old age as well as the basic needs of the elderly. Chapter 2 deals with the importance of knowing the life history of each senior and motivations for meaningful activation. Chapter 3 describes the individual activating practices with a description of the benefits, or possible negative effects, on users of residential service Activations help and support the consolidation and development of physical and mental strength, as well as maintaining or improving self-sufficiency. The efforts to activate elderly people must fully respect the individual abilities and requirements of each person as not everyone is happy to participate in therapeutic practices. Activations have an irreplaceable role in comprehensive care for the elderly in residential facilities. Nursing homes offer a variety of activities and possibilities for spending leisure time. Care in nursing homes aims to make the last stage of life easier and more pleasant for their elderly residents and helps them to use all the abilities each has in order to gain a sense of self-worth, meaningful life and harmony.

Plant responses to deer browsing and the consequences for further browsing
Dudlová, Tamara ; Lepková, Barbora (advisor) ; Štenc, Jakub (referee)
(English) The bachelor thesis focuses on the interaction of plants and herbivores, specifically deer. The main question is if (and possibly how) the changes induced in the plants by deer browsing affect the probability of re-browsing. I tried to answer the question by reviewing published literature. Plants respond to browsing by tolerance (compensatory growth) or resistance (production of defensive chemical compounds), depending on the plant's life strategy. Tolerance prevails in adult woody plants and grasses; resistance prevails in young woody plants and forbs. In resistant plants, browsing increases the content of phenolic substances and decreases the cellulose content, while tolerant species react in the opposite way. It is the contents of these substances, which are negatively correlated, that are key to food selection by deer. Large species of deer generally prefer plants with more cellulose, which they are able to digest efficiently. Smaller species prefer plants with lower cellulose content and higher concentration of simple sugars. These more nutritious plants are protected from browsing by phenolic substances, which smaller deer species are able to neutralize more effectively. Only a few studies have addressed the issue of re-browsing of the same plants, and their results are ambiguous....

Indian Partition - life histories in the context of geopolitical developments
Mubeenová, Geti ; Novotný, Josef (advisor) ; Hons, Pavel (referee)
The following thesis focuses on the long-term consequences of Partition of India on a micro-level. The thesis examines the life-history of a family that has been spatially divided owing to the decision of some family members who decided to migrate from India to Pakistan. Current, and past familial relations as well as the relationship of the spatially displaced family, specifically focusing on the relationship of the Indo-Pakistani family parts have been analysed. The life history is understood as a possible way how to explain Partition. Partition is presented in its broader historical-geographical context, specifically, the decolonization of the Indian subcontinent. The thesis incorporates selected approaches that establish a multi-dimensional framework and its interactions. The critical geopolitical approach explains the political standpoints of former political leaders as well as preconditions of Partition. The New histories approach gives way to personal spoken historical testimonies of family members in both countries, that apply nationalised representations of Partition and family ties. Additionally, feminist perspectives insight into how all three generations of the family understand and perceive topics important to the family's history, including how do they define 'home'. From a long-term...

Reproductive biology and sexual dimorphism in the lizard Lepidophyma smithii (Squamata: Xantusiidae)
Kukačková, Dominika ; Kratochvíl, Lukáš (advisor) ; Frynta, Daniel (referee)
The squamata reptiles present a wide array of reproductive strategies. In the genus Lepidophyma from the neotropical family Xantusiidae, there are 19 species, all of them live- bearing and diploid. Obligatory unisexuality is also present in some species. This obligatory unisexuality did not evolve via hybridization, which is unique among vertebrates. The genus thus presents a very interesting, but still poorly little explored group. Only recently our team has discovered a facultative unisexuality in Lepidophyma smithii. The unisexually produced offsprings are not fully homozygous are of both sexes, which is unique for vertebrates as well. The aim of my work is to describe the basic reproductive biology of this species, e.g. the relationship between female size and clutch size and offspring size. Additionally, my work focuses on sexual dimorphism. I tested whether L. smithii is dimorphic in body length and head size. These traits are often sexually dimorphic in squamatesu. Also, I documented the ontogeny of sexual dimorphism and reconstructed growth curves for males and females.

Ecology of Veliidae and Mesoveliidae (Heteroptera: Gerromorpha)in Central Europe
DITRICH, Tomáš
Ecology of Veliidae and Mesoveliidae (Hemiptera: Heteroptera: Gerromorpha) was studied in selected European species. The research of these non-gerrid semiaquatic bugs was especially focused on voltinism, overwintering with physiological consequences and wing polymorphism with dispersal pattern. Hypotheses based on data from field surveys were tested by laboratory, mesocosm and field experiments. New data on life history traits and their ecophysiological consequences are discussed in seven original research papers (four published journal papers, two submitted papers and one communication in conference proceedings), creating core of this thesis.

Narrative journey to the childhood
Čmejrková, Světla
Narrative activity of the authors of written autobiographies is viewed as an attempt to transform their life stories into texts, to communicate their experience, and to construct their identity through narratives. The genre of written autobiography is analyzed from the point of view of its temporal structure, focalization and ethic stance.
