dna dna Relatedness among thermoactinomyces species thermoactinomyces candidus as a synonym of thermoactinomyces vulgaris and thermoactinomyces thalpophilus as a synonym of thermoactinomyces sacchari
2000Co-Authors: Jung-hoon Yoon, Yong Kook Shin, Yong-ha ParkAbstract:DNA-DNA Relatedness of all validly described Thermoactinomyces species was determined to infer the genetic relationships between them. The levels of DNA-DNA Relatedness among the type strains of Thermoactinomyces species ranged from 2-5 to 92.8%. Based on DNA Relatedness data, the type strains of Thermoactinomyces intermedius, Thermoactinomyces putidus, Thermoactinomyces dichotomicus and Thermoactinomyces peptonophilus were considered to be distinct species of the genus Thermoactinomyces. However, the relationship between the type strains of Thermoactinomyces vulgaris and Thermoactinomyces candidus and the relationship between the type strains of Thermoactinomyces sacchari and Thermoactinomyces thalpophilus were reevaluated from levels of DNA-DNA Relatedness. The independent DNA Relatedness values between Thermoactinomyces vulgaris KCTC 9076T and Thermoactinomyces candidus KCTC 9557T were 90.8 and 92.8%. Thermoactinomyces thalpophilus KCTC 9789T and Thermoactinomyces sacchari KCTC 9790T exhibited independent values of 85.6 and 87.3%. Accordingly, on the basis of DNA-DNA Relatedness data together with 16S rDNA sequence data determined recently, it is proposed that Thermoactinomyces candidus should be considered as a synonym of Thermoactinomyces vulgaris and Thermoactinomyces thalpophilus be considered as a synonym of Thermoactinomyces sacchari.

DNA-DNA Relatedness among Thermoactinomyces species: Thermoactinomyces candidus as a synonym of Thermoactinomyces vulgaris and Thermoactinomyces thalpophilus as a synonym of Thermoactinomyces sacchari
2000Co-Authors: Jung-hoon Yoon, Yong Kook Shin, Yong-ha ParkAbstract:DNA-DNA Relatedness of all validly described Thermoactinomyces species was determined to infer the genetic relationships between them. The levels of DNA-DNA Relatedness among the type strains of Thermoactinomyces species ranged from 2.5 to 92.8%. Based on DNA Relatedness data, the type strains of Thermoactinomyces intermedius, Thermoactinomyces putidus, Thermoactinomyces dichotomicus and Thermoactinomyces peptonophilus were considered to be distinct species of the genus Thermoactinomyces. However, the relationship between the type strains of Thermoactinomyces vulgaris and Thermoactinomyces candidus and the relationship between the type strains of Thermoactinomyces sacchari and Thermoactinomyces thalpophilus were reevaluated from levels of DNA-DNA Relatedness. The independent DNA Relatedness values between Thermoactinomyces vulgaris KCTC 9076(T) and Thermoactinomyces candidus KCTC 9557(T) were 90.8 and 92.8%. Thermoactinomyces thalpophilus KCTC 9789(T) and Thermoactinomyces sacchari KCTC 9790(T) exhibited independent values of 85.6 and 87.3%.

genetic evidence of extra pair paternity and intraspecific brood parasitism in the monk parakeet
2013Co-Authors: Maria Carla De Aranzamendi, Juan Martinez, Juan F Masello, Enrique H BucherAbstract:Introduction: The monk parakeet (Myiopsitta monachus) is a widespread invasive species native to southern South America that has become established in many regions of the world. Monk parakeets breed in a large, fully enclosed structure built from twigs, which consist of one to many individual brooding chambers. The species has been considered to be socially and genetically monogamous. However, genetic Relatedness of adults to juveniles in the native area was found to be lower than expected for monogamy. To assess the significance of this discrepancy, we examined individual and population genetic patterns of microsatellite loci at two sites in Cordoba province, Argentina. Results: We sampled 154 nestlings and 42 adults in Cordoba, Argentina. Mean value of pairwise Relatedness of nestlings within chambers was about 0.40. Contrarily, Relatedness of nestlings between chambers was close to zero. We found a considerable degree of variation in nestling pairwise Relatedness and parentage within chambers, including chambers with combinations of unrelated, half-sib, and full-sib nestlings. The proportion of sibling Relatedness indicated monogamy in 47% and extra pair-paternity in 40% of the chambers. We also found intra-brood parasitism in 3% of the chambers. Conclusions: Our results indicate that the monk parakeet is sexually polygamous in its native range in Argentina, which is consistent with the observed mean value of Relatedness of adults to juveniles of about 0.4. We also confirm the existence of intra-brood parasitism. High density of monk parakeets may favor occurrence of extra-pair paternity and intra-brood parasitism in the native sites.
