This master is theses describes the activity of the European badger (Meles meles) in the cadastral territory of Horní Studenec. The activity was monitored in relation to weather, time of sunrise and sunset and the moon phase in different seasons of a year. This thesis consists of two parts, practical and theoretical. The theoretical part is based on a literary research. The practical part analyzes data acquired by the author through a camera trap monitoring and personal observation at a particular badger warren. The outcome of this thesis is the finding that the following factors have influence on badger is behavior: lunar moon phase, daily minimum temperature and changes in external environment caused by human intervention.

Drosophila melanogaster has been extensively used as a model organism to study diverse facets of biology, including host-pathogen interactions and the basic biology of its pathogens. I have used the fruit fly as a model to study elementary aspects of Nora virus biology, such as the role of the different proteins encoded by the virus genome. Nora virus, an enteric virus transmitted via the feca-oral route, does not cause any obvious pathology in the fly, although the infection is persistent. Nora virus genome consists of a positive strand RNA that is translated in four open reading frames (ORF).  Since sequence homology studies did not yield much information about the different Nora virus proteins, I have used the cDNA clone of the virus to construct mutants to identify the specific function of each protein. My results have shown that, 1) The protein(s) encoded by ORF 1 are crucial for the replication of the virus genome. 2) The C-terminus of the ORF 1-encoded protein (VP1), is an inhibitor to the RNAi pathway. 3) The transmembrane domain in the N-terminus of the ORF2-encoded protein (VP2) is important for the formation of Nora virus virions. 4) The ORF 3-encoded protein (VP3) forms α-helical trimers and this protein is essential for the stability of Nora virus capsid.                                                     I have also performed RNA sequencing to investigate the transcriptional response of D. melanogaster in response to Nora virus infection and my results indicate that,                        5) The upregulation of genes related to cellular stress and protein synthesis and the downregulation of basal digestive machinery, together with the induction of upd3, implies major gut epithelium damage and subsequent regeneration.

Drosophila melanogaster has been widely used as a model organism to study the immune responses against bacteria, fungi, parasites and viruses. Here, I present a D. melanogaster virus as a model to study persistent virus infections. I have discovered and characterized the Nora virus, a small picorna-like RNA virus able to persistently infect D. melanogaster. The Nora virus genome encodes four open reading frames; a feature not present in other picorna-like viruses. The Nora virus is not closely related to any other virus family, but rather is the first virus in a new family of picorna-like viruses. The major replicative proteins of this virus are encoded in the second open reading frame and the capsid proteins are encoded in the fourth open reading frame. The sequence of the capsid proteins are not obviously related to any other previously described protein. By looking at expressed sequence tags (EST) projects, we identified an EST sequence from the parasitic wasp Nasonia which appears to encode proteins that have sequence similarity to the Nora virus capsid proteins. I have shown that the Nora virus persists in the fly intestine however I did not observe serious pathological effects in the infected flies. The virus is shed through feces and the transmission occurs horizontally via the ingestion of virus-contaminated food. Moreover, I observed variability in the viral titers among single flies of the same infected stock. Some flies are able to clear the Nora virus but not others and this phenomenon seems to be titer-dependent. Surprisingly, none of the known Drosophila antiviral responses play a role against the Nora virus. In conclusion, my work shows that studying the Nora virus interaction with the Drosophila immune system can lead to new findings on viral persistence mechanisms of RNA viruses and of Drosophila viral innate immunity.

In the middle of the nineteenth century, the train came to Sweden. It has been just over 150 years and a lot has happened. With the train and its station came more then just a means of transportation, it turned Sweden from a developing country into one of the most modern. In the small Swedish cities and on the countryside, the stations became a central node, a meeting point and a place to gather. The train passed through previously isolated areas where the stations became not only just that but also a window towards the rest of the world. This project is a study of the Swedish train station and a humble proposal on how to treat them, what to do with them and when to do it (now).
