Doctor of Philosophy (PhD) / This thesis explores the experiences of white women who partnered Chinese men and their children in southern Australia during the late nineteenth and early twentieth centuries. It has been based on a wide range of sources, including newspapers, government reports, birth and marriage records, personal reminiscences and family lore, and highlights the contradictory images and representations of Chinese-European couples and their families which exist in those sources. It reveals that in spite of the hostility towards intimate interracial relationships so strongly expressed in discourse, hundreds of white women and Chinese men in colonial Australia came together for reasons of love, companionship, security, sexual fulfilment and the formation of family. They lived, worked and loved in and between two very different communities and cultures, each of which could be disapproving and critical of their crossing of racial boundaries. As part of this exploration of lives across and between cultures, the thesis further considers those families who spent time in Hong Kong and China. The lives of these couples and their Anglo-Chinese families are largely missing from the history of the Chinese in Australia and of migration and colonial race relations more generally. They are historical subjects whose experiences have remained in the shadows and on the margins. This thesis aims to throw light on those shadows, contributing to our knowledge not only of interactions between individual Chinese men and white women, but also of the way mixed race couples and their children interacted with their extended families and communities in Australia and China. This thesis demonstrates that their lives were complex negotiations across race, culture and geography which challenged strict racial and social categorisation.

O século XXI iniciou para a Federação Russa marcado por sensíveis mudanças, tanto no âmbito doméstico como na política externa adotada pelo país, muitas delas implementadas com o intuito de reverter os efeitos perversos de escolhas feitas durante o Governo Yeltsin (1991-1999). No plano externo, o objetivo principal da Rússia passou a ser a retomada do posto de grande potência no sistema internacional. A fim de atingir tal meta, a política externa do primeiro Governo Putin (2000-2008) e do Governo Medvedev (2008-2012) foi pautada pelas seguintes características: defesa da multipolaridade, eurasianismo, pragmatismo, a utilização da geoeconomia na política externa e maior assertividade. Nos primeiros anos do século XXI, a multipolaridade defendida por Moscou vai se tornando realidade. Com vistas a ser um dos polos desta nova configuração sistêmica de poder, o segundo Governo Putin (2012-) investe no projeto da União Eurasiana, uma organização regional que abrigará preferencialmente países do espaço pós-soviético e tem como alicerce os avanços da União Aduaneira e do Espaço Econômico Comum, organizações formadas por Rússia, Cazaquistão e Bielorrússia. A criação da União Eurasiana indica a revalorização do multilateralismo, o que em alguma extensão modifica a política externa russa, pois a ela acresce uma nova característica. Diante de tal cenário, surge a dúvida: por que o segundo Governo Putin investe na União Eurasiana e no multilateralismo? A hipótese adotada é a de que a resposta ao questionamento proposto é encontrada na análise das conjunturas regional e sistêmica nas quais a Federação Russa está inserida no início dos anos 2010. / The 21st century brought significant changes to the Russian Federation, both in the domestic and the foreign policies of the country. Most of the policies were implemented with the goal of reversing the perverse effects of the policies implemented during the Yeltsin years (1991-1999). In relation to foreign affairs, the main goal of Russia was to regain the position of a great power in the international system. In this sense, the foreign policies of the first Putin mandate (2000-2008) and of the Medvedev government (2008-2012) were guided by advocating multipolarity, eurasianism, pragmatism, economization of the foreign policy and assertiveness. In the early 21st century, the multipolarity advocated by Moscow begins to take shape. With the goal of becoming one of the poles of the new systemic configuration of power, the second Putin government (2012-) investes in the Eurasian Union project. The goal is to establish a regional organization encompassing mainly the post-soviet space countries. The organization, in turn, is based on the advancements of the Customs Union and the Common Economic Space. These two organizations include the Russian Federation, Kazakhstan and Belarus. The creation of the Eurasian Union represents the rebirth of multilateralism, which, to some extent, changes Russia’s foreign policy by adding a new trait to it. Thus, the following question arises: why does the Putin government invest in the Eurasian Union and in multilateralism? The hypothesis of the present dissertation is that the answer may be in the evaluation of the regional and systemic situations in which the Russian Federation has been inserted in the early 2010s.

The eurasian perch (Perca fluviatilis Linnaeus, 1758) is considered as very perspective species for breeding at intensive aquaculture, where was successful domesticated. Consumption of eurasian perch is increased at present. The greatest grow of consumption is mainly in countries of alpine region and in Scandinavian countries. The aim of experiment was monitor and character spawning of domesticated eurasian perch in controlled conditions of breed. It was determinated fertility and then fertilization of eggs. The next aim was make incubation of fertilization eggs and determinate hatching. After hatch was determinated total length of larvae and its quality by the help of osmotic shock. Domesticated eurasian perch is spawned without problems in controlled conditions of breed. The resulting data of domesticated perch are worse than date of non-domesticated perch in some spawning characteristic. This problem will resolve with gaining knowledge about spawning of eurasian perch. The greatest problem is hatching of eggs, which is very low during spawning of domesticated perch.

Robust monitoring combined with genetic analyses are important approaches to protect and manage large carnivore populations successfully. The aim of this master thesis is to analyse Eurasian lynx (Lynx lynx) population within whole Slovakia for the first time using 15 microsatellite loci. Noninvasive genetics is an effective tool for monitoring animal species with large home ranges and low population densities. Noninvasive samples including feces, hair, urine and buccal swabs were collected together with tissue samples from dead (mostly roadkill) individuals. 187 samples were collected between 2017-2019, resulting in 59 successful genotypes. Two samples were incorrectly determined in the field and excluded from further analyses since they were wildcat samples. For population genetics analyses and demography, the dataset from the "Veľké šelmy 2" project was extended with 98 genotypes in collaboration with the Institute of Vertebrate Biology CAS. Overall, 68 lynx individuals were detected in the dataset of 155 genotypes. Relatedness analysis resulted in 67 significant relationships of the first degree and 9 significant relationships of the second degree. These results suggest a high relatedness among the whole population. According to the present thesis, Slovakian lynx population has the third lowest...

Global warming leads to an increased browning of lakes across the northern hemisphere. This browning can due to benthic light-limitation cause hypoxic bottom conditions which can have negative impact on the fish production in the northern lakes. In this study, I obtained data from a large-scale experiment to test if the removal of anoxic bottom conditions in the hypolimnion affects Eurasian perch (Perca fluviatilis) populations. This was done with a Before-After, Control-Impact design in two adjacent lakes by altering the oxygen conditions in the hypolimnion in one lake while the other remained as control. To analyse if experimental oxygenation of an anoxic hypolimnion altered perch performance, I analysed samples of individual growth (based on back-calculated growth from operculum bone readings), condition, diets and stomach fullness in perch before and after oxygenation from the control and impact lake. The results showed that growth, condition, and stomach fullness increased in the treatment lake but not in the control lake, suggesting that resource availability increased for perch with the removal of anoxic hypolimnion conditions. However, a decline in population abundances was also observed over time within both lakes, which may provide at least an alternative explanation of the observed responses. Still, I hypothesize that the oxygenation at least partially increased the resource abundance in brown lakes, thus increasing fish growth and size.

Movement increases the probability for an individual to find food resources, but also increase the metabolic costs and exposure to predators. Hence, swimming behavior of fish is strongly coupled to fitness. Even though swimming activity has been studied in numerous laboratory settings, less is known about in situ activity and its dependence on abiotic factors (temperature, light conditions and barometric pressure). In this study I hypothesized that the activity increases with 1) increasing temperature and decrease with 2) barometric pressure variability and 3) average light conditions (h/day). In order to test the universality of the three hypotheses I also searched for size dependent effects. Fish activity (km/day) was measured in three lakes on individual fish (N=14-21 per lake) using acoustic telemetry providing tracking of fish at a time resolution from seconds to hours. A positive correlation between temperature and swimming activity in line with my first hypothesis was only observed in one of the lakes. The activity decreased with increased variability in barometric pressure in two of the lakes, a finding supporting my second hypothesis. Meanwhile increased light conditions (h/day) decreased activity in one of the lakes, as predicted by my third hypothesis. Nevertheless, none of my hypotheses were valid in all three of the lakes and perch reacted differently to the abiotic factors. One of the possible explanations for this is the importance of size differences as I noticed that the swimming activity differed between bigger and smaller individuals. My findings suggest that not only the temperature, barometric pressure and light conditions alone predict the activity in perch, but also the fish individual size, predation and the metabolic costs linked to thermoregulation.
