Resumo: | Understanding the processes that shape the current distribution patterns of species is one of the main goals of Ecology. In this thesis, we aimed to understand which factors are related to the distribution of the turtle diversity, a group of ectothermic animals whose diversity patterns are still little known, over time and space. To that end, we used distribution data from continental chelonian species, as well as life history information (habitat type and body size), and reconstructed a phylogenetic hypothesis for the group using molecular data. Turtles had a burst of lineage diversification during the irradiation of the Emydidae family, which is probably linked to an event of ecological opportunity. In addition, aquatic animals had higher rates of diversification than terrestrial animals, which helps to explain the current greater diversity of aquatic animals. Turtle richness distribution along the continents is mainly influenced by climatic variables such as temperature and precipitation, but the time when lineages first colonized the continental regions also influences this pattern. Beta diversity among chelonian communities is mainly influenced by the geographical distance between communities, and communities from different biogeographic realms are structured by different drivers. Finally, body size diversity of turtles is also influenced by temperature, and small animals are more common in cold areas. |

Nesta tese, visamos entender quais fatores estão relacionados à distribuição da diversidade de quelônios, grupo de animais ectotérmicos cujos padrões de diversidade ainda são pouco conhecidos, ao longo do tempo e do espaço. Para esse fim, usamos dados de mapas de distribuição das espécies de quelônios continentais, além de informações de história de vida (tipo de hábitat e tamanho corporal), e reconstruímos uma hipótese filogenética para o grupo usando dados moleculares. O grupo dos quelônios apresentou uma explosão de diversificação durante a irradiação da família Emydidae, o que está provavelmente ligado a um evento de oportunidade ecológica. Além disso, animais aquáticos apresentaram taxas de diversificação mais elevadas que os animais terrestres, o que ajuda a explicar a maior diversidade de animais aquáticos atuais. A distribuição da riqueza de quelônios ao longo dos continentes é influenciada principalmente por variáveis climáticas tais como temperatura e precipitação, porém o intervalo de tempo desde o qual as áreas foram colonizadas também influencia nesse padrão. A diversidade beta entre as comunidades de quelônios é influenciada principalmente pela distância geográfica entre as comunidades, e comunidades de diferentes de domínios biogeográficos são estruturadas de modo diferenciado. Finalmente, a diversidade de tamanhos corporais dos quelônios também é influenciada pela temperatura, de modo que animais menores são mais comuns em áreas mais frias.Submitted by Marlene Santos (marlene.bc.ufg@gmail.com) on 2018-07-12T20:09:09Z No. of bitstreams: 2 Tese - João Fabrício Mota Rodrigues - 2017.pdf: 7026938 bytes, checksum: bb5eb1fc81f363b414aa3c9e80fb3429 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2018-07-13T10:42:29Z (GMT) No. of bitstreams: 2 Tese - João Fabrício Mota Rodrigues - 2017.pdf: 7026938 bytes, checksum: bb5eb1fc81f363b414aa3c9e80fb3429 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2018-07-13T10:42:30Z (GMT).

Understanding the processes that shape the current distribution patterns of species is one of the main goals of Ecology. In this thesis, we aimed to understand which factors are related to the distribution of the turtle diversity, a group of ectothermic animals whose diversity patterns are still little known, over time and space. To that end, we used distribution data from continental chelonian species, as well as life history information (habitat type and body size), and reconstructed a phylogenetic hypothesis for the group using molecular data. Turtles had a burst of lineage diversification during the irradiation of the Emydidae family, which is probably linked to an event of ecological opportunity. In addition, aquatic animals had higher rates of diversification than terrestrial animals, which helps to explain the current greater diversity of aquatic animals. Turtle richness distribution along the continents is mainly influenced by climatic variables such as temperature and precipitation, but the time when lineages first colonized the continental regions also influences this pattern. Beta diversity among chelonian communities is mainly influenced by the geographical distance between communities, and communities from different biogeographic realms are structured by different drivers. Finally, body size diversity of turtles is also influenced by temperature, and small animals are more common in cold areas. |
