<p>The threats of human encroachment and climate change are increasing and understanding the interplay between genetic diversity, fitness, and ecological variation has become critical for predicting adaptive responses and species extinction risk. Decreasing genetic diversity, owing to population decline or inbreeding, can be detrimental at the level of the individual, population, or species. One of the major challenges for evolutionary and conservation biologists is identifying the specific genetic components that influence inter-individual variation in fitness remains. As a direct link between genetic-make up and individual fitness, the Major Histocompatibility Complex (MHC) is critical to the activation of the adaptive immune system. Biologist have suggested that in addition to influencing an individual's health, variation at the MHC may be related to an individual's survival and reproductive success. Here, I test this hypothesis using two populations of ring-tailed lemurs (<italic>Lemur catta</italic>) at long-term study sites to achieve individual and population-level comparisons of MHC diversity and to integrate new genetic technology with behavioral, ecological, and environmental data. First, I address the difficulty of genotyping large populations at hypervariable genes by using next generation sequencing and suggest improvements to current methods. Second, I describe patterns of variation at the MHC-DRB 2nd exon, including diversity between alleles, individuals, and populations. Next, I examine the relationship between MHC-DRB diversity and measures of immunocompetence, parasitism, and survival within a broader framework of ecological variability across captive and wild conditions. Because the MHC is also thought to be important in mate choice and reproduction, I use an experimental approach in captive individuals to investigate possible mechanisms of MHC-based signaling through olfactory communication. Lastly, I link a female's MHC genotype to her reproductive success in the wild and explore if this relationship is altered by environmental stressors. The results of this dissertation emphasize the increasing feasibility of using genetic approaches to investigate the fitness correlates of genetic diversity non-model systems. These advances are critical for future studies and the integration of behavioral, ecological, and genetic perspectives in semi-natural and wild environments.</p> / Dissertation

Essa região possui baixos índices de cobertura vegetal nativa, e, diante desse cenário que pode ocasionar desequilíbrio ambiental com prejuízo às atividades humanas e também devido às obrigações previstas em leis, faz-se necessário a definição de áreas nas quais as ações de restauração ecológica devem acontecer com prioridade. Para tanto, utilizou-se a metodologia de Combinação Linear Ponderada, em que as variáveis escolhidas são combinadas, atribuindo-se pesos para cada uma delas de forma a se obter o resultado final. Foram utilizados como fontes de informação e análise os dados de Fragilidade Natural à Erosão, Vulnerabilidade Natural dos Aquíferos à Poluição, Áreas de Preservação Permanente, Inventário Florestal, Conectividade do Estado de São Paulo, Unidades de Conservação e Áreas declaradas como prioritárias por outros instrumentos e definição dos pesos para as variáveis utilizadas foi feita a partir de uma matriz AHP (Analytic Hierarchy Process). Num primeiro momento, os dados foram combinados, gerando uma hierarquização em cinco classes, e partir dessa, foram destacadas as áreas com extensão superior a 5 hectares e que estivesse na classe de maior prioridade. Os resultados mostraram que há áreas prioritárias por toda extensão da UGRHI 22, com destaque para as APPs de forma geral e para as UPHs Baixo Paranapanema Margem Direita, Tributários do Rio Paraná e Santo Anastácio. Concluiu-se que os dados gerados representam adequadamente as áreas prioritárias na área da UGRHI e pela necessidade de implantação de projetos de restauração ecológica nos locais indicados. / This work aimed to identify areas for ecological restoration into the of UGRHI 22, located in Pontal do Paranapanema, in the western of the São Paulo State, Brazil. This region has low indices of native vegetation cover and, in face of this scenario that can cause environmental imbalance and affect human activities and also due to legal obligations, it is necessary to define areas in which ecological restorations actions must take place prioritarily. To achieve the results, the Weighted Linear Combination methodology was used, which means that the chosen variables are combined, and weights were assigned for each one of that. The definition of these weights was made by the application of and AHP (Analytic Hierarchy Process) matrix and the data used as sources of information and to the analysis in this work were: Natural Fragility to Erosion, Natural Pollution Aquifer Vulnerability, Permanent Protection Area, Forest Inventory, Connectivity from the São Paulo State, Conservation Units and Areas that were declared as priority by other instruments. At first, the data were combined in order to generate a five classes hierarchy map, and then, the areas within the highest priority class and with extension larger than 5 hectares were selected. The final results showed that are priority areas throughout the extension of the UGRHI 22, with emphasis on the Permanent Protected Areas and the UPHs Right Margin of Lower Paranapanema, Tributaries of Parana River and Santo Anastacio. It was concluded that the results properly represent the priority areas in the UGRHI and the need to implement restoration projects in these places.
