Hormonal and developmental regulation of sex-specific traits in squamate reptiles
Defence status: DEFENDED(Univerzita Karlova, Přírodovědecká fakulta, 2025)Date of defense: 28. 3. 2025The persistent puzzles of sexual dimorphism in reptiles - especially regarding sex-specific differences in body size, and male-typical traits such as behaviour and colouration - continue to intrigue researchers. This ... -
Úloha ARE5 ABCF proteinů v antibiotické rezistenci a regulaci u rodu Streptomyces
Defence status: DEFENDED(Univerzita Karlova, Přírodovědecká fakulta, 2025)Date of defense: 28. 3. 2025Microorganisms need to quickly adapt to environmental changes, which leads to optimization of their gene expression and its manifestation in various phenotypic traits. The dynamics and complexity of this plasticity are not ... -
Studium genetického pozadí solidních tumorů
Defence status: DEFENDED(Univerzita Karlova, Přírodovědecká fakulta, 2025)Date of defense: 28. 3. 2025Abstract The dissertation discusses different methodological approaches for detection of various genetic alterations in three types of solid tumors: thyroid, colorectal and pancreatic. Modern oncological research is based ... -
Bioinformatic evaluation of mass spectrometric data obtained by analysis of proteins modified by reactive oxygen species
Defence status: DEFENDED(Univerzita Karlova, Přírodovědecká fakulta, 2025)Date of defense: 28. 3. 2025The field of structural mass spectrometry (MS) is a rapidly developing area comprising of many versatile techniques for the characterisation of biomolecules under native or near-native conditions. Among them, reactive ... -
O původu organických aerosolů v ČR
Defence status: DEFENDED(Univerzita Karlova, Přírodovědecká fakulta, 2025)Date of defense: 28. 3. 2025The chemical composition of atmospheric aerosols (AA) has been shown to exert a significant influence on human health and atmospheric phenomena over the course of several decades. Consequently, there is a growing emphasis ... -
The occurrence of sunning clusters as a part of thermoregulation in red wood ants Formica polyctena
Defence status: DEFENDED(Univerzita Karlova, Přírodovědecká fakulta, 2025)Date of defense: 27. 3. 2025The occurrence of sunning clusters in red wood ants is a remarkable phenomenon and it is a ubiquitous behavior observed in all nests we studied. This specific behavior is supposed to play an important role in the nest ... -
Studium struktury a interakcí proteinů pomocí hmotnostní spektrometrie - vývoj metod a jejich aplikace.
Defence status: DEFENDED(Univerzita Karlova, Přírodovědecká fakulta, 2025)Date of defense: 28. 3. 2025Despite significant advancements in structural biology methods, studying the structure, dynamics and interaction mechanisms of protein and nucleic acid complexes remains a challenging process. This is illustrated by the ... -
Preparation and characterization of functionalized surfaces for desorption-ionization mass spectrometry
Defence status: DEFENDED(Univerzita Karlova, Přírodovědecká fakulta, 2025)Date of defense: 28. 3. 2025Structural proteomics combined with mass spectrometry, is a rapidly evolving scientific discipline that focuses on the characterization of the three-dimensional structures of proteins, as well as their dynamics. However, ... -
The Vanishing Agent: Analysis of Causality in Biology
Defence status: DEFENDED(Univerzita Karlova, Přírodovědecká fakulta, 2025)Date of defense: 27. 3. 2025The Vanishing Agent: Analysis of Causality in Biology Summary I am trying to show how the autonomy of both biology, and the concept of organisms it uses, depend on the notion of causality. The physicalist takeover of biology ... -
Biodiversity and speciation in moss-inhabiting flea beetles (Coleoptera: Chrysomelidae: Alticini)
Defence status: DEFENDED(Univerzita Karlova, Přírodovědecká fakulta, 2025)Date of defense: 27. 3. 2025Abstract. Flightless insects are both a striking evolutionary model, and a source of unknown species diversity challenging to taxonomists. This thesis explores the evolution, biodiversity, and biogeography of moss-inhabiting ...
