The southeastern U.S. is a hotspot of aquatic biodiversity and endemism in the upland and Coastal Plain regions. One component of this biodiversity is the Pygmy Sunfishes of the genus Elassoma. I used next-generation sequencing to aid in the understanding and conservation of these enigmatic fish. My first chapter focused on one of the most restricted species in the U.S. the Spring Pygmy Sunfish Elassoma alabamae. In this study I found four distinct genetic populations, evidence of founder effects, and that a newly discovered population is native. My second chapter focused on the Everglades Pygmy Sunfish Elassoma evergladei a more widespread Coastal Plain species. In that chapter, I found five unique lineages with the westernmost lineage representing an undescribed species. My third chapter focused on sequencing of the mitochondrial genome of E. alabamae for use in non-invasive detection, which can aid in discovery of new populations for this species.

The thesis focused to population ecology and genetics of subalpine species Gentiana pannonica. Pollination ecology of species and generative reproduction in different habitat (primary vs. secondary) were investigated in the field. Genetic variation and structure of G. pannonica populations were studied in three disjunct parts of its distribution range: the Eastern Alps, the Bohemian Forest, and the Giant Mts. Present distribution of G. pannonica in the central past of the Bohemian Forest were processed.

Introdução: A endometriose afeta 10 a 15% das mulheres em idade reprodutiva e há evidências crescentes de que o estresse oxidativo está envolvido na sua patogênese. Os polimorfismos na região controladora do DNA mitocondrial podem levar à replicação e à transcrição alterada dos genes mitocondriais, o que pode afetar a função mitocondrial e, consequentemente, a geração intracelular de espécies reativas de oxigênio. Descobertas recentes indicam que os polimorfismos do DNA mitocondrial (mtDNA) estão relacionados à endometriose em populações coreana e indiana. Objetivo: Avaliar a associação entre polimorfismos e haplogrupos do DNA mitocondrial e a presença de endometriose em mulheres brasileiras. Métodos: Pacientes com idade entre 18 e 50 anos foram divididas nos grupos endometriose (n = 90) e controle (n = 92). O primeiro grupo incluiu mulheres com diagnóstico histológico de endometriose e estadiamento cirúrgico, enquanto o segundo grupo incluiu pacientes submetidas à cirurgia para laqueadura tubária, leiomioma ou cistos ovarianos benignos, sem evidência de endometriose. O DNA foi extraído a partir de amostras de sangue periférico seguido do sequenciamento de Sanger e eletroforese capilar. Os polimorfismos foram determinados comparando as sequências obtidas com a Sequência padrão de Cambridge Revisada. Resultados: As frequências dos polimorfismos T16217C (14,4% vs. 5,4%; p = 0,049), G499A (13,3% vs. 4,3%; p = 0,038), T236C (5,6% vs. 0%; p = 0,028) e G185A (6,7% vs. 0%; p = 0.013) foram maior no grupo endometriose em comparação ao grupo controle, respectivamente, enquanto as frequências dos polimorfismos T146C (18,9% vs 32,6%; p = 0,042) e 573.2C (5,6% vs. 29,3%; p < 0.001) foram menores. A distribuição dos haplogrupos foi semelhante entre os grupos endometriose e controle. Nenhuma diferença foi observada nos haplogrupos de acordo com o estádio ou localização da doença. Conclusão: Os polimorfismos T16217C, G499A, T236C e G185A do DNA mitocondrial foram relacionados à presença de endometriose, enquanto T146C e 573.2C foram relacionados à ausência de doença, em amostra de mulheres brasileiras. Não foram observadas diferenças significativas entre os haplogrupos mitocondriais / Background: There is increasing evidence that oxidative stress is a major factor in the pathogenesis of endometriosis, a prevalent disease that affects 5-15% of reproductive-aged women worldwide. Polymorphisms in the control region of mitochondrial DNA (mtDNA) can lead to the altered replication and transcription of mitochondrial genes, thereby affecting both overall mitochondrial function, and the intracellular generation of reactive oxygen species. Objective: The present study investigated whether the incidence of mtDNA polymorphisms and/or haplogroups is associated with endometriosis in a Brazilian population. Methods: Female patients (aged 18-50 years) were enrolled in the present study, and assigned to either endometriosis (n = 90) or control (n = 92) group. The former group comprised patients who had received a histological diagnosis of endometriosis and had been assigned a surgical stage, while the latter comprised patients who had undergone gynecological surgery for tubal ligation, leiomyoma, or ovarian cysts, and showed no evidence of endometriosis. DNA was extracted from peripheral blood samples, and then subjected to Sanger sequencing and capillary electrophoresis. Polymorphisms were identified by comparing the isolated mtDNA sequences with the revised Cambridge Reference Sequence. Results: The frequency of some identified polymorphisms was found to be higher in the endometriosis group than in the control group, including polymorphisms T16217C (found in 14.4% and 5.4% of endometriosis- and control-group members, respectively; p=0.049), G499A (13.3% vs. 4.3%; p=0.038), T236C (5.6% vs. 0%; p=0.028), and G185A (6.7% vs. 0%; p=0.013). In contrast, polymorphisms T146C (18.9% vs. 32.6%; p=0.042) and 573.2C (5.6% vs. 29.3%; p < 0.001) were found to occur at a lower frequency in the endometriosis compared to the control group. Observed haplogroup frequencies were similar between the endometriosis and control groups, and did not appear to be affected by either disease location and/or staging. Conclusion: mtDNA polymorphisms T16217C, G499A, T236C, and G185A were found to be associated with endometriosis, while conversely, T146C and 573.2C were shown to be associated with an absence of disease in the analyzed Brazilian population. No significant differences were observed between the mitochondrial haplogroups of patients with, versus without endometriosis
