Resumo: | It is extremely important the knowledge about ecological characteristics in different biomes and how each population behaves to adversities of the environment they live in. It has been observed that some tick species widely distributed may have genetic and / or biological differences between populations. The tick Amblyomma parvum has a wide distribution Neotropical with an extensive list of hosts. To try to elucidate these gaps on the subject, studies were developed in Laborat?rio de Ixodologia and Biologia Molecular in Departamento de Parasitologia Animal in Universidade Federal Rural do Rio de Janeiro. When comparing the life cycle of this parasite from three colonies of different locations (Pantanal Sul-matogrossense, Cerrado, Goias and Chaco, Argentina) it was observed that the complete cycle of A. parvum was completed in an average period of 104.2; 99.6 and 100.7 days for the Pantanal, Chaco and Cerrado respectively. We conclude that the biological parameters of the three populations are quite similar. It is also not fully understood as terrestrial arthropods survive the temporary flooding following heavy rains then the purpose of the second chapter was to compare the effect of immersion in the life cycle in order to respond to water stress can affect and/or changes in the reproductive efficiency. It can be observed that the Pantanal population was more sensitive to immersion even though the observation ecdysis in group 96 hours. Despite this in group 48 of the Pantanal population there was no continuation of the cycle while the Chaco and Cerrado populations continued its cycle even after the nymphs remain submerged 48 hours. It can be observed that from 72 hours immersion causes a deleterious effect on this species. The results reported here suggest that the ability to survive underwater for a period is a additional aspect of the biology of this species of tick. With respect to the molecular analysis was demonstrated in literature genetic divergence (3.0 to 3.7%) of A. parvum Argentinean and Brazilian. However, analysis of a single gene is not robust enough to make inferences about the significance of the genetic differences between different populations, so new sequences of molecular markers obtained from A. parvum belonging to different locations in Argentina and Brazil have been evaluated. Results for the genes 12S and COI there was a significant difference point of to consider them as distinct species in South America, 3.8% and 7.1% respectively. But when we observe the results for the ITS2 gene there was not enough difference to characterize different species. View of these biological and molecular results are recommended further analysis with new samples of new locations in order to elucidate this question about the possibility of this kind in South America be different species. |

View of these biological and molecular results are recommended further analysis with new samples of new locations in order to elucidate this question about the possibility of this kind in South America be different species.? de suma import?ncia o conhecimento sobre caracter?sticas ecol?gicas em diferentes biomas e como cada popula??o se comporta frente a adversidades do meio em que vive. Tem-se observado que algumas esp?cies de carrapatos amplamente distribu?dos podem apresentar diferen?as gen?tica e/ou biol?gicas entre as popula??es. O carrapato Amblyomma parvum possui uma ampla distribui??o Neotropical com uma lista extensa de hospedeiros. Para tentar elucidar essas lacunas sobre o assunto, estudos foram desenvolvidos nos Laborat?rios de Ixodologia e Biologia Molecular do Departamento de Parasitologia Animal da Universidade Federal Rural do Rio de Janeiro. Ao comparar o ciclo biol?gico deste parasito proveniente de tr?s col?nias de distintas localidades (Pantanal Sul-matogrossense, Cerrado goiano e Chaco argentino) observou-se que o ciclo completo de A. parvum foi completado em um per?odo m?dio de 104,2; 99,6 e 100,7 dias para os biomas Pantanal, Chaco e Cerrado respectivamente. Conclui-se que os par?metros biol?gicos das tr?s popula??es s?o bastante semelhantes. Tamb?m n?o ? totalmente compreendido como artr?podes terrestres sobrevivem ?s inunda??es tempor?rias que seguem fortes chuvas ent?o o objetivo do segundo cap?tulo foi comparar o efeito da imers?o sob o ciclo de vida a fim de responder como o estresse h?drico pode afetar e/ou alterar a efici?ncia reprodutiva. Pode-se observar que a popula??o Pantanal demonstrou ser mais sens?vel em rela??o ? imers?o mesmo tendo a observa??o de ecdise no grupo 96 horas. Apesar disso no grupo 48 horas da popula??o Pantanal n?o houve continua??o do ciclo enquanto que as popula??es Chaco e Cerrado continuaram seu ciclo mesmo depois que as ninfas permanecerem 48 horas submersas. Pode-se observar que a partir de 72 horas a imers?o causa um efeito delet?rio para essa esp?cie. Os resultados aqui relatados sugerem que a capacidade de sobreviver submersos por um per?odo ? um aspecto adicional da biologia dessa esp?cie de carrapato. No que diz respeito ? an?lises moleculares na literatura foi demonstrado diverg?ncia gen?tica (3,0 a 3,7%) entre A. parvum argentinos e brasileiros. No entanto, a an?lise de apenas um gene n?o ? suficiente para fazer infer?ncias robustas sobre a signific?ncia das diferen?as gen?ticas entre diferentes popula??es, ent?o novas sequ?ncias de marcadores moleculares obtidas a partir de A. parvum pertencentes a diferentes localidades da Argentina e Brasil, foram analisadas. para o gene 12S e COI houve uma diferen?a significativa a ponto de consider?-las como esp?cies distintas na Am?rica do Sul, 3,8% e 7,1% respectivamente. Mas ao observarmos os resultados para o gene ITS2 n?o houve diferen?a suficiente para caracterizar esp?cies diferentes. Diante desses resultados biol?gicos e moleculares s?o recomend?veis novas an?lises com novas amostras de novas localidades, a fim de elucidar essa d?vida sobre a possibilidade desse g?nero da Am?rica do Sul ser esp?cies diferentes.Submitted by Jorge Silva (jorgelmsilva@ufrrj.br) on 2019-11-13T18:21:08Z No. of bitstreams: 1 2015 - Michele da Costa Pinheiro.pdf: 4006380 bytes, checksum: f9fb9ac88f68d69607bb4b8d249fa6fd (MD5)Made available in DSpace on 2019-11-13T18:21:08Z (GMT).

description |
It is extremely important the knowledge about ecological characteristics in different biomes and how each population behaves to adversities of the environment they live in. It has been observed that some tick species widely distributed may have genetic and / or biological differences between populations. The tick Amblyomma parvum has a wide distribution Neotropical with an extensive list of hosts. To try to elucidate these gaps on the subject, studies were developed in Laborat?rio de Ixodologia and Biologia Molecular in Departamento de Parasitologia Animal in Universidade Federal Rural do Rio de Janeiro. When comparing the life cycle of this parasite from three colonies of different locations (Pantanal Sul-matogrossense, Cerrado, Goias and Chaco, Argentina) it was observed that the complete cycle of A. parvum was completed in an average period of 104.2; 99.6 and 100.7 days for the Pantanal, Chaco and Cerrado respectively. We conclude that the biological parameters of the three populations are quite similar. It is also not fully understood as terrestrial arthropods survive the temporary flooding following heavy rains then the purpose of the second chapter was to compare the effect of immersion in the life cycle in order to respond to water stress can affect and/or changes in the reproductive efficiency. It can be observed that the Pantanal population was more sensitive to immersion even though the observation ecdysis in group 96 hours. Despite this in group 48 of the Pantanal population there was no continuation of the cycle while the Chaco and Cerrado populations continued its cycle even after the nymphs remain submerged 48 hours. It can be observed that from 72 hours immersion causes a deleterious effect on this species. The results reported here suggest that the ability to survive underwater for a period is a additional aspect of the biology of this species of tick. With respect to the molecular analysis was demonstrated in literature genetic divergence (3.0 to 3.7%) of A. parvum Argentinean and Brazilian. However, analysis of a single gene is not robust enough to make inferences about the significance of the genetic differences between different populations, so new sequences of molecular markers obtained from A. parvum belonging to different locations in Argentina and Brazil have been evaluated. Results for the genes 12S and COI there was a significant difference point of to consider them as distinct species in South America, 3.8% and 7.1% respectively.
