The effects of domestication on animals’ behaviors and morphology are well known and documented. Changes due to domestication include higher sociability, decreased fearfulness, and increased boldness. These changes have been documented in the chicken breed known as White Leghorn (Gallus gallus domesticus), which is a domesticated relative to the Red Junglefowl (Gallus gallus). Though domestication have altered the chicken’s behavior, its effect on the cognitive learning capabilities of the chicken is still unclear, which is the focus of the study. Two tests were conducted in this study: associative learning and spatial learning. The fowls natural desire to remain close to other fowl was used as the main motivation for completing the tests. The associative learning test was performed by testing the two breeds of associating an item with finding their way to their flock. The spatial learning test was performed by measuring the time needed for an individual to return to their flock from behind an obstacle. For the associative learning test, a significant difference between the cognitive learning capability of the two breeds could be found for part 2 (tests 11-20), as well between part 1 and part 2 within the breed White Leghorn. Between the sexes no significant difference could be seen, but within the females, a significant difference was detected between part 1 and part 2. For the spatial learning test, no significant difference could be found between the two breeds nor the sexes. No correlation could be found between associative- and spatial learning test on an individual level. Due to few significant results, further studies should be conducted to confirm the effects of domestication on learning.

The question of horse domestication have long been debated and discussed amongst scholars. There have been serval theories about when and where horse domestication first took place and when horses became our loyal companions that we build a lot of our society around. The Eurasian steppes have long been subject of these discussions. Within recent years a lot of DNA- studies have been done on the subject to try to answer these questions. In 2018 a DNA-study showed that the prewalski horse, who have been thought to be the last wild horse on earth, is ancestors to the horses found at Botai. The Botai culture has long been thought to be the origin of domesticated horses. In 2021 even more shocking discoveries came to light. It was revealed that all modern day horses comes from the same genetic line called DOM2. The DOM2 linage originates from the lower Volga-Don region and started to spread across Eurasia around 2000 BC. These revelations made people reevaluate previous assumptions concerning early use of horses, like the Yamnaya culture expansion to Europe which was previously believed to have taken place on horseback. This study aims to address the impact of new DNA studies on our understanding of horse domestication and its spread, analysing various theories, DNA research, and archaeological findings. / Frågan om hästdomesticering har länge debatterats och diskuterats bland forskare. Det har funnits flera teorier om när och var hästdomesticering först ägde rum, och när hästarna blev våra trogna följeslagare som vi byggde mycket av vår samhällsstruktur kring. Den eurasiska stäppen har länge varit föremål för dessa diskussioner. Inom de senaste åren har många DNA- studier gjorts om ämnet för att försöka besvara dessa frågor. År 2018 visade en DNA-studie att przewalski hästen, som man tidigare trott var den sista vilda hästen i världen, är en ättling till hästarna som hittats vid Botai. Botaikulturen har länge förmodats vara ursprunget till domesticerade hästar. År 2021 fördes ännu mer chockerande upptäckter fram i ljuset. Det avslöjades att alla moderna hästar kommer från samma genetiska linje som kallas DOM2. DOM2-linjen har sitt ursprung i nedre Volga-Don-regionen och började sprida sig över Eurasien cirka 2000 f.Kr.. Denna upptäckt fick människor att omvärdera tidigare antaganden kring tidig användning av hästar, som yamnayakulturens expansion till Europa som tidigare trotts ha skett till häst. Denna studie syftar till att adressera de nya DNA-studiernas påverkan på vår förståelse av hästdomesticering och dess spridning, analysera olika teorier, DNA- forskning och arkeologiska fynd.

The Inferno from La Commedia, by Dante Alighieri has been translated into Japanese about a dozen times in the past 110 years. In this comparative analysis, seven of those are analysed and compared with regards to how cultural terms were translated and to what degree the different translators tried to make a word-by word translation for certain selected passages. Nine such passages, with a total of 93 lines were chosen. About 60 words were analysed per translator and the main goal was to determine whether if they have a tendency towards foreignisation or domestication. A Natural Language Processing analysis was also conducted to assess the similarity of translations in terms of word usage. Besides the oldest translation, which is quite different when it comes to both word usage and grammar and is therefore considered an outlier, two main groups emerge. One that tends to translate more word-by-word than the other, which is freer. All in the first group imitate the Italian pronunciation of cultural terms using katakana, while most in the latter prefer the current Japanese term. In between these groups appears one translator, which is more consequently following the change of words in a similar way like Dante did when referring to Virgilio, while others tend to use the same word several times.

Over the past twenty years there has been an exponential increase in the investigation of maternal effects. Understanding the adaptive function of maternal allocation strategies is integral to interpreting the evolutionary outcomes of sexual selection. Thus, model animal systems that facilitate experimental manipulation and controlled investigation of the physiological and behavioural mechanisms underlying maternal effects are important to evolutionary biologists. The zebra finch (Taeniopygia guttata) has been used as a model to investigate avian life-history, signalling behaviour, neurophysiology, mate choice, and more recently, maternal effects. However, a potentially influential and rarely addressed problem with this species is the process of domestication. Within this thesis we aimed to both test current predominant maternal allocation hypotheses, but for the first time in both domesticated and wild zebra finches. Chapter 2 develops on earlier work using domesticated zebra finches that has demonstrated differential allocation of maternally derived yolk androgens and antioxidants in eggs dependent on paternal attractiveness. This chapter specifically tests the ratio of these two yolk resources within individual eggs and shows that the balance of androgens to antioxidants varies by offspring sex and paternal attractiveness. Specifically, we found that mothers allocated a smaller androgen to antioxidant ratio to daughters when paired to green ringed (unattractive) males compared to red ringed (attractive) males. This pattern was reversed for sons, where mothers allocated a larger ratio of androgen to antioxidant when paired to red ringed (attractive) compared to green ringed (unattractive) males. We also show that brood sex ratio depended on both female condition and male attractiveness. It is concluded that investigating female allocation of individual resources within egg yolks may lead to incorrect assumptions on offspring fitness consequences, and that individual female state is an important consideration when predicting a resource allocation strategy. Throughout this thesis colour bands are used as a method to manipulate male attractiveness. In chapter 3 the influence of these bands was further tested to elucidate whether they affect male behaviour or quality. Wild birds were used for this chapter as preferences for bands based on colour have only once been demonstrated in wild birds and it was felt this should also be replicated. We confirmed a female preference for males based on colour bands worn in mate choice trials, with red bands preferred over green. Interestingly, we also found that colour of bands worn by males for an extended period in the single sex aviary influenced both their song rate and condition. Males that had worn red bands sang more in mate choice trials than both green banded or un-banded males. In addition red banded males were found to be in significantly better physical condition. These data suggest that earlier experiments in which it has been assumed that colour bands do not manipulate any form of intrinsic male quality should be re-evaluated. The final two data chapters, 4 and 5, return to investigating maternal allocation in response to male attractiveness, but for the first time in wild birds. Chapter 4 presents an experiment that was conducted on a wild, nest box breeding population of birds. Maternal resources allocation was investigated in both an experimental manipulation of male attractiveness, and also by correlating resource allocation with paternal phenotypic traits. A limited sample size meant few conclusions could be drawn from the experimental study, but significant positive correlations were found between both egg size and yolk testosterone (T) concentration and male phenotypic traits. This suggested that wild zebra finches may follow a positive investment strategy but requires further investigation. In chapter 5 experiments were repeated on wild birds that had been brought into captivity, to allow both an improved sample size and further control of influential environmental features. Again, female allocation strategies are tested using colour bands to manipulate male attractiveness, to allow direct comparisons with work on domesticated zebra finches. We found that females laid significantly heavier eggs for attractive compared to unattractive males, supporting the positive investment hypothesis. In addition we found an interaction between offspring size and paternal attractiveness treatment, with daughters of red banded (attractive) males being smaller than sons. This experiment is the first to demonstrate the influence of colour bands on maternal allocation in wild zebra finches and also provides further support for the positive investment hypothesis in this species. The final chapter discusses how overall patterns of female allocation were shown to be similar among wild and domesticated populations. It is concluded that demonstrated variations between populations and/or contexts reported in these studies cannot be explained by inherent differences between wild and domesticated individuals. Thus, the zebra finch remains a robust and reliable model for testing the evolution of avian maternal allocation strategies.

Ce travail vise une meilleure compréhension de l'adaptation aux conditions d'élevage par une approche comportementale basée sur la comparaison de diverses populations de téléostéens pour trois espèces, l'une marine, le bar (Dicentrarchus labrax), les deux autres d'eau douce, l'omble chevalier (Salvelinus alpinus) et la truite commune (Salmo trutta). La thèse s'articule en deux parties qui ont permis : 1) de tester des facteurs biotiques et abiotiques sélectionnés en fonction de leur importance en élevage du bar et de l'omble chevalier. 2) de caractériser les effets de la domestication sur le comportement par le biais d'une comparaison entre des bars ou des truites sauvages et domestiqués à des âges différents et dans des contextes variables (challenges, labyrinthe). Dans la première partie, les travaux réalisés sur l'omble chevalier ont montré que la présence d'un refuge artificiel durant la phase de nutrition endogène induisait une forte diminution de la mobilité accompagnée de meilleures performances de croissance et d'une survie plus importante, que la taille de l'œuf et l'environnement social jouaient un rôle important sur le comportement alimentaire et la mobilité des juvéniles dans les semaines qui suivent la première nutrition exogène. Les travaux réalisés sur le bar ont montré qu'un aliment végétal ne modifiait pas les capacités d'apprentissage en condition d'auto-alimentation ni leurs capacités cognitives en situation de test en labyrinthe, mais qu'il semble réduire l'activité de nage et la libération à court terme du cortisol. Une autre expérience a montré que la pratique du tri et l'environnement social qui en résulte, en conditions d'auto-alimentation, a peu d'influence sur la demande, le rythme, le gaspillage alimentaires, la structure sociale, les performances de croissance et le statut physiologique. Une période de trois semaines de jeûne, enfin, ne modifie pas la structure sociale et les manipulateurs principaux sont les mêmes avant et après cette période, ce qui pourrait être lié à l'existence de traits de personnalité basés sur le pourcentage d'activation de la tige tactile du dispositif d'auto-alimentation. Dans la seconde partie de la thèse, l'expérience sur la truite a mis en évidence un effet de la domestication sur l'activité de nage avant et après application d'un stress lumineux, en utilisant un matériel biologique contrôlé par génotypage (vitesse angulaire plus élevée chez les individus sauvages, vitesse moyenne et distance parcourue plus importantes chez les individus domestiqués). Les expériences réalisées sur le bar ont comparé des populations sauvages capturées à l'état larvaire dans le milieu naturel à des populations standard industrielles. La première a montré l'influence combinée de l'âge et de mécanismes d'ordre ontogénique sur l'activité de nage et le taux de réponse de fuite (diminution chez les deux catégories de larve). L'impact de la domestication se traduit par des différences entre individus sauvages et domestiquées (vitesse angulaire et vigilance plus élevés chez les individus sauvages). En situation de labyrinthe, la domestication ne semble pas avoir d'influence sur le grégarisme et la cognition chez le bar, mais il existe une forte variabilité individuelle. La discrimination de la familiarité, enfin, n'a pu être mise en évidence que chez les individus domestiqués.L'approche comportementale a permis de révéler une plasticité en réponse à quelques facteurs abiotiques et abiotiques, qui constitue un véritable levier adaptatif pour les téléostéens en élevage. L'effet de la domestication sur le comportement a également été démontré ainsi que l'influence de l'âge et des mécanismes ontogéniques dont la nature reste à déterminer. Cette thèse s'inscrit dans la lignée des travaux qui vise à sélectionner les téléostéens sur leurs traits de personnalité dans l'optique d'une adaptation optimale en élevage ou dans la perspective de programmes de repeuplement.

本研究以内容分析法分析台灣公共電視與TVBS新聞台晚間新聞中國際新聞的數量、編排、資訊娛樂化與馴化策略的呈現，共分析公共電視140則，TVBS新聞台80則，合共221則國際新聞。 本研究發現：1）台灣電子媒體的國際新聞在内容上依然以嚴肅的政治與經濟主題為主。然而，資訊娛樂化的主題在台灣電子媒體中依然佔相當的比例。2）商業電視台較公營電視台更常以資訊娛樂為主題與以娛樂性角度報導國際新聞。而根據本研究所發展出來的「内在資訊娛樂化指數」，商業電視台之資訊娛樂化程度較公共電視高。3）引用西方媒體如CNN與BBC的國際新聞之「内在資訊娛樂化指數」較低，而引用非西方媒體或沒有引用外國媒體的國際新聞「内在資訊娛樂化指數」則最高。4）本研究發現台灣電視國際新聞中落後國家較的資訊娛樂化程度較已發展國家與發展中國家為低。5）本研究也發現在外在資訊娛樂化的部分，台灣電子媒體在視覺包裝的使用較不常見。 本研究結果同時也指出台灣電子媒體之國際新聞的地域角度中較重視國外新聞。在馴化策略的使用中不管是地圖的使用或影響的説明都偏低，研究同時也發現在本地消息來源的使用上，台灣電子媒體均以名人與專家為主。比較公營電視台與商業電視台則發現公營電視台較重視國際新聞中本地消息來源之聲音。 / Employing content analysis, this study examines the quantity, format, infotainment phenomena and domestication strategies of international news in two Taiwan television stations. This study analyzes a total number of 221 international news, consisting 140 international news from Taiwan Public Broadcast Station, and 80 from TVBS News Channel. From this study, it is concluded that: 1) political related topic dominate Taiwan international news, however infotainment topic such as human interest, entertainment, and sports news also occupied a large part of international news in Taiwan; 2) commercial station are more vulnerable to infotainment both in news topic and news perspective than public station, and according to the “Internal Infotainment Index” developed in this study, commercial station shows a higher degree of infotainment than public station; 3) news material that comes from Western sources such as CNN and BBC shown less degree of infotainment than news material that comes from non-Western sources or original news; 4) news of developed countries and developing countries have higher degree of infotainment than less developed countries; 5) visual package such as background music and animation are not often employ in international news in Taiwan. This study also concluded that international news in Taiwan emphasizes in foreign event. The usage of map and influence as linkage of domestic audience and international news are rare. This study also found that both stations are more likely to refer to or cite local celebrities and professionals to emphasis the importance of certain international affairs; however public station is stress more on voice of local public than the commercial station in international news.

Animal domestication, the process where animals become adapted to living in proximity to humans, is associated with the alteration of multiple traits, including decreased fearfulness and stress response. With an estimated population of 50 billion, the domesticated chicken is the most populous avian species in the world. Hundreds of chicken breeds have been developed for meat and egg production, hobby or research purposes. Multidirectional selection and the relaxation of natural selection in captivity have created immense phenotypic diversity amongst domesticates in a relatively short evolutionary time. The extensive phenotypic diversity, existence of the wild ancestor, and feasibility of intercrossing various breeds makes the chicken a suitable model animal for deciphering genetic determinants of complex traits such as stress response. We used chicken domestication as a model to gain insights about the mechanisms that regulate stress response in an avian species. We studied behavioural and physiological stress response in the ancestral Red Junglefowl and one of its domesticated progenies, White Leghorn. An advanced intercross between the aforementioned breeds was later used to map genetic loci underlying modification of stress response. The general pattern of the stress response in chickens was comparable with that reported in mammals, however we identified distinctive differences in the stress modulatory pathways in chickens. We showed that changes in the expression levels of several stress modulatory genes in the brain, the pituitary and the adrenal glands underlie the observed modified stress response in domesticated chickens. Using quantitative trait loci (QTL) mapping, several QTL underlying stress induced corticosterone, aldosterone and baseline dehydroepiandrosterone (DHEA) levels were detected. As a next step, we combined QTL mapping with gene expression (eQTL) mapping and narrowed two QTL down to the putative causal genes, SERPINA10 and PDE1C. Both of these genes were differentially expressed in the adrenal glands of White Leghorn and the Red Junglefowl, had overlapping eQTL with hormonal QTL, and their expression levels in the adrenal glands were correlated with plasma levels of corticosterone and al-dosterone. These two genes thus serve as strong candidates for further functional investigation concerning modification of the stress response during domestication. This dissertation increase the knowledge about genetics and physiology of the stress response in an avian species and its modification during domestication. Our findings expand the basic knowledge about the stress response in chicken, which can potentially be used to improve welfare through appropriate genetic selection.

Today, the issues related to the presence of bears and wolves in the Czech Republic are more frequently discussed due to their occasional occurrence. The significant part of the public still considers these predators dangerous and they even think that a man is supposed to be their potential prey. A lot of surveys confirming this have been already taken, but none of them was focused on the views of primary and secondary schools students. As they are a part of the school education system, their views on the large carnivores should be mainly shaped by it. A questionnaire-based survey was used to find the attitudes of students. The first part of the questionnaire focused on the students' opinions about the dangerousness of predators, its reasons and common wolf presence in the Czech Republic. The second part of the questionnaire is focused on the domestic dog, which has wolf origins. It deals mainly with the attitudes of students to selected dog breeds, dog domestication awareness and views on the so- called "fighting breeds". This work has been aimed at identification of attitudes of the primary and secondary school students from different regions of the Czech Republic to the selected predators. The survey was also taken at primary schools in the High Tatras Mountains, an area where all the large...
