The schedule of growth, reproduction and survivorship of an individual are the key components of life history, which reflect fitness performance of a genotype. Examining the variation in life history performance among genotypes provides an avenue for which genotypic fitness differences can be compared. The parthenogenetic freshwater zooplankton, Daphnia pulicaria, is a model organism to investigate and disentangle the genotypic from the phenotypic influences of life history variation. While Daphnia spp. life history has been extensively studied, few have examined the effect of low food concentrations on life history traits. Since Daphnia spp. are frequently subjected to periods food limitation caused by natural phytoplankton cycles, it is necessary to understand how individuals respond in low food environments in order to obtain an accurate representation of life history responses among genotypes. In this study, I conducted a set of highly controlled laboratory experiments using multiple genotypes of Daphnia pulicaria under a range of food-limited conditions in order to gain insight into the environmental and genotypic responses of life history traits. I measured a suite of life history traits, growth, reproduction and survivorship, as discrete elements for each individual and synthesized these traits into a representation of the life history schedule. This provided an accurate method to compare genotypes and allowed for identification of trade-offs between life history traits. My results indicate a significant effect of low food concentration on life history traits, causing a decrease in performance of all traits. Additionally, genotypic differences occurred in most traits, however these differences only manifested within the intermediate food levels. There were no genotypic differences in daily reproductive rate, indicating that genotypes only differ in the number of individuals reproducing within an environment. Allocation-based trade-offs among these life history traits were examined within a genotype, however the only trade-off identified was between reproduction and survivorship and this only manifested at low food levels. Even though these genotypes do not co-exist in the same lakes, similar patterns occurred in trade-offs among genotypes. This potentially indicates that trade-offs among genotypes occur due to the same physiological mechanisms witnessed at the individual level. / Thesis (Master, Biology) -- Queen's University, 2011-08-14 11:32:27.808

Esta dissertação analisa as memórias do general e agente secreto francês, Paul Aussaresses, veterano da Resistência Francesa na Segunda Guerra Mundial e das guerras da Indochina (1946-1954) e da Argélia (1954-1962). Sua competência como agente de informação adquirida nesses eventos o tornaram elemento importante dentro dos Serviços Secretos franceses. Em virtude de sua especialidade, a doutrina da guerra revolucionária um método militar não convencional de luta contra insurgentes que pressupõe prisões arbitrárias, tortura, execuções sumárias e terror psicológico sobre a população Aussaresses ministrou cursos na escola de agentes especiais norte-americana, Fort Bragg, na Carolina do Norte, entre 1961 e 1963 (no contexto da Guerra do Vietnã), bem como no Brasil durante a ditadura civil-militar, onde foi adido entre 1973 e 1975. Além disso, comerciou armas e realizou missões delicadas pela França em diversos países. Foi um anônimo até os 82 anos quando, em novembro de 2000, deu ao jornal Le Monde um depoimento sobre as torturas e execuções sumárias sistemáticas que praticara na Argélia. Suas memórias, publicados depois disso, mostram outra imagem da França, bem como desvendaram seu sistema de ação durante a Guerra Fria. No primeiro capítulo, fazemos uma descrição do seu contexto de atuação profissional. No segundo, analisamos suas memórias propriamente ditas, tirando delas o modus operandi dos franceses no contexto da Guerra Fria. No terceiro, analisamos a influência francesa nas forças armadas brasileiras bem como as relações entre a ditadura brasileira e a democracia francesa, com foco nas questões militares e econômicas sugeridas pelas memórias do General / This dissertation analyzes the memories of the General and french secret agent, Paul Aussaresses, veteran of the French Resistance in World War II and the wars in Indochina (1946-1954) and Algeria (1954-1962). His competence as information agent, acquired in these events, turned him an important element within the French Secret Service. Because of his specialty: the doctrine of revolutionary war (an unconventional military method of fighting against insurgents, that assumes arbitrary arrests, torture, summary executions and psychological terror on the population), Aussaresses taught courses in the North American school of special agents, in Fort Bragg, North Carolina, between the years of 1961 and 1963 (in the context of the Vietnam War), as well as in Brazil during the civil-military dictatorship, where he was military attaché between 1973 and 1975. Moreover, he traded weapons and conducted, to France, undercover missions in several countries. He lived in anonymity until 82 years old when, In November of 2000, he gave to the newspaper Le Monde a testimonial about the systematic torture and summary executions that had practiced in Algeria. His memories, published after this, show another image of France as well as uncovered its system of military action during the Cold War. In the first chapter of this dissertation, we make a description of the context of his professional practice. In the second, we analyze his memories, extracting them the modus operandi of the France in the context of the Cold War. In the third, we analyze the french influence in the brazilian armed forces and the relations between the brazilian dictatorship and french democracy, always with the focus in the military and economic matters suggested by the memories of the General Aussaresses
