| Abstract Amazon parrots are long-lived birds with highly developed cognitive skills, including vocal learning. Several parrot mitogenomes have been sequenced, but important aspects of their organization and evolution are not fully understood or have limited experimental support. The main aim of the present study was to describe the mitogenome of the blue-fronted Amazon, Amazona aestiva, and compare it to other mitogenomes from the genus Amazona and the order Psittaciformes. We observed that mitogenomes are highly conserved among Amazon parrots, and a detailed analysis of their duplicated control regions revealed conserved blocks. Population level analyses indicated that the specimen analyzed here seems to be close to A. aestiva individuals from Bahia... |

| Mitochondrial gene rearrangement events, especially involving tRNA genes, have been described more frequently as more complete mitochondrial genome sequences are becoming available. In the present work, we analyzed mitochondrial tRNA gene rearrangements between two bee species belonging to the tribes Apini and Meliponini within the "corbiculate Apidae". Eleven tRNA genes are in different genome positions or strands. The molecular events responsible for each translocation are explained. Considering the high number of rearrangements observed, the data presented here contradict the general rule of high gene order conservation among closely related organisms, and also represent a powerful molecular tool to help solve questions about phylogeny and evolution in... |

| We sequenced the complete mitochondrial genome of the pirarucu, Arapaima gigas, the largest fish of the Amazon basin, and economically one of the most important species of the region. The total length of the Arapaima gigas mitochondrial genome is 16,433 bp. The mitochondrial genome contains 13 protein-coding genes, two rRNA genes and 22 tRNA genes. Twelve of the thirteen protein-coding genes are coded on the heavy strand, while nad6 is coded on the light strand. The Arapaima gene order and content is identical to the common vertebrate form, as is codon usage and base composition. Its control region is atypical in being short at 767 bp. The control region also contains a conserved ATGTA motif recently identified in the Asian arowana, three conserved... |
