ABSTRACT.A new molecular phylogeny for akodontine rodents from Brazil was proposed. The phylogenetic tree was enriched with the area of occurrence and with information on the karyotype of the samples. Based on this enriched tree, and with a described methodology, hypotheses were proposed on the karyotype and area of occurrence of the ancestors of each Clade. Thus it was possible to discuss hypotheses on chromosome evolution of the group, and on dispersion events from the "area of original differentiation" of akodontines in the Andes. Chromosome evolution started with high diploid numbers (2n=52) and showed a tendency to reduction (until 2n=14 in more recent clades). Independent side-branches of the tree showed 2n reduction and in one case the 2n increased. At least four dispersion events from the Andes down to South-eastern Brazil were proposed. The results should suggest the direction of new studies on comparative karyology. KEYWORDS.Brazilian akodontines, chromosome evolution, biogeography, molecular phylogeny. RESUMO. Filogenia molecular, cromossomos e dispersão em akodontinos do Brasil (Rodentia, Sigmodontinae).Uma nova filogenia molecular para roedores akodontinos do Brasil é proposta. A árvore filogenética foi enriquecida com a área de ocorrência e com informações sobre o cariótipo das amostras. Baseado nisto, e com a metodologia descrita, foram propostas hipóteses sobre as características do cariótipo e sobre a área de ocorrência dos ancestrais de cada clado. Assim, foi possível discutir hipóteses sobre evolução cromossômica do grupo, e sobre eventos de dispersão a partir da área de diferenciação original dos akodontinos nos Andes. A evolução cromossômica começou com números diplóides altos (2n=52) e mostrou uma tendência a redução (até 2n=14 em clados mais recentes). Ramos independentes da árvore mostraram redução do 2n e num caso aumentou o numero diplóide. Foram propostos pelo menos quatro eventos de dispersão dos Andes até o Brasil Sul-Oriental. Os resultados indicam a direção de novos estudos em cariologia comparada. PALAVRAS-CHAVE.Akodontinos do Brasil, evolução cromossômica, biogeografia, filogenia molecular.

“…Geological evidence suggests that alterations in central South America occurred gradually, first, with the development of the Amazon River (late Miocene) and later with alteration of its drainage patterns, from the western Andes to northeastern Amazonia, between the late and post Pleistocene (Rasanen et al, 1987;Smith and Patton, 1993;Hoorn et al, 1995;daSilva and Patton, 1998). These events led to cladogenesis of the Brazilian and Andean Clades and are reflected in the high degree of genetic differentiation among populations in the Brazilian Clade, leading to the occurrence of at least four closely related population groups with 5.25% nt divergence within this clade (Fig.…”

Cytochrome b DNA sequence data (ca. 1,140 bp) of 44 Alouatta caraya, including 42 specimens from three localities of Brazil and two from Bolivia, were used for phylogenetic reconstructions and population studies. Seventeen haplotypes were identified, eight of which were present in more than one individual. Seven of these eight haplotypes were shared by individuals from a same locality and one by individuals from two localities. We found 26 variable sites along the entire gene, consisting of 18 transitions and eight transversions; most replacements occurring at the third codon position (65.39%) in contrast to first and second positions (26.92 and 7.69%, respectively). In the sample collected at Chapada dos Guimarães (Brazil), nucleotide and haplotype diversity estimates were pi=0.002325 and h=0.8772, respectively. Maximum parsimony analysis grouped all haplotypes in two clades, separating Bolivian haplotypes from Brazilian haplotypes, the grouping of which did not show a straightforward correspondence with geographic distribution. Median-joining and TCS network pointed to haplotypes 11 or 12 as the most likely ancestral ones. Mismatch distribution and the goodness-of-fit test (SSD estimate=0.0027; P=0.6999) indicated that the population from Chapada dos Guimarães experienced a demographic expansion, in agreement with the median-joining star-like pattern, although this finding could not be confirmed by Fu's F(s) test.
