Genetic evaluation of the mating system in the blue-and-yellow macaw (Ara ararauna, Aves, Psittacidae) by DNA fingerprinting
More than 90% of birds are socially monogamous, although genetic studies indicate that many are often not sexually monogamous. In the present study, DNA fingerprinting was used to estimate the genetic relationships between nestlings belonging to the same broods to evaluate the mating system in the socially monogamous macaw, Ara ararauna. We found that in 10 of 11 broods investigated, the nestli...
متن کاملMolecular markers for population genetic analyses in the family Psittacidae (Psittaciformes, Aves)
The selection of molecular markers for population studies is an important tool for biodiversity conservation. The family Psittacidae contains many endangered and vulnerable species and we tested three kinds of molecular markers for their potential use in population studies of five psitacid species: 43 hyacinth macaws (Anodorhynchus hyacinthinus), 42 blue-and-yellow macaws (Ara ararauna), 23 red...
متن کاملIntraspecific phylogeography of the Japanese threadfin bream, Nemipterus japonicus (Perciformes: Nemipteridae), from the Persian Gulf and Indo-West Pacific: a preliminary study based on mitochondrial DNA sequence
The Japanese threadfin bream, Nemipterus japonicus, the most abundant and crucially economic Nemipterus species is widespread throughout the Indo-West Pacific. The species has been studied widely for various aspects but genetic studies are scanty. This preliminary study contributes to the species phylogeography through the study of the genetic diversity and historical demography of N. japonicus...
متن کاملPerched at the mito-nuclear crossroads: divergent mitochondrial lineages correlate with environment in the face of ongoing nuclear gene flow in an Australian bird.
Relationships among multilocus genetic variation, geography, and environment can reveal how evolutionary processes affect genomes. We examined the evolution of an Australian bird, the eastern yellow robin Eopsaltria australis, using mitochondrial (mtDNA) and nuclear (nDNA) genetic markers, and bioclimatic variables. In southeastern Australia, two divergent mtDNA lineages occur east and west of ...
متن کاملGenetic variation in the narrow-clawed crayfish (Astacus leptodactylus) populations as assessed by PCR-RFLP of mitochondrial COI gene
The genetic variation and population structure of narrow-clawed crayfish (Astacus leptodactylus) was examined by means of polymerase chain reaction (PCR) restriction fragment length polymorphism (RFLP) analysis of the cytochrome oxidase subunit I (COI) of mitochondrial DNA. A total of 194 adult specimens were collected from seven sample sites including, two in the south Caspian Sea and one each...
