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...

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...
