First karyotypical description of two American Ciconiiform birds, Mycteria americana (Ciconiidae) and Platalea ajaja (Threskiornithidae) and its significance for the chromosome evolutionary and biological conservation approaches

By Mercival Roberto Francisco and Pedro Manoel Galetti Junior


The karyotypes of Mycteria americana (Ciconiidae) and Platalea ajaja (Threskiornithidae) are described. Both species have a diploid number of 2n = 72. There are slight chromosome morphology differences, which could be related to distinct chromosome evolution pathways of these two families. Besides a better understanding of the chromosome relationships among Ciconiiformes, this first chromosome characterization of M. americana and P. ajaja is an important tool for the conservation of both species
