dc.description.abstract | The fishes of the order Perciformes are characterized as an important model for
understanding the genetic structure of marine populations, because besides they
present examples of conservation chromosomal, also they present the karyotype
diversification for some groups. Gobiidae family is the most specious in the marine
environment. Among its representatives, many species are part of a cryptic fauna
little noticed and studied, a wide distribution with behavioral and reproductive
characteristics, that make them conducive to the action of biogeographical barriers.
Morphologically this family presents reduced body structures through simplification
and regressions. Despite their importance in evolutionary inferences, cytogenetics
data are incipient facing their species diversity, especially with western Atlantic
species. In order to estimate the evolutionary diversity in Gobiidae, it were developed
cytogenetic analysis and the standards body, through geometric morphometrics in
five species on the Brazilian coast, Coryphopterus glaucofraenum, Bathygobius
mystacium, B. soporator, Ctenogobius smaragdus e C. Boleosoma. The data show
significant karyotype and morphological diversity among the species. The pericentric
inversions and mergers play an important role in chromosomal evolution of this
family, causing karyotypic structural and numerical differences in all species.
Karyotypic and morphological comparisons among geographic samples of B.
soporator from the coast of Maranhão, Rio Grande do Norte and Bahia showed
cytogenetics patterns commons, but different morphological patterns. A sample from
the Atol das Rocas revealed conspicuous morphological and karyotypic
differentiation of another continental populations, confirming the presence of a new
island species. The approaches done reveal diversification consistent with
characteristics of a group of low vagile and largely able to environmental selection
due from peculiar ecological requirements | |
