Karyotype description and comparative analysis in Ringed Kingfisher and Green Kingfisher (Coraciiformes, Alcedinidae)

Autor: Tiago Marafiga Degrandi, Jean Carlo Pedroso de Oliveira, Amanda de Araújo Soares, Mario Angel Ledesma, Iris Hass, Analía del Valle Garnero, Ricardo José Gunski

Publikováno v: Comparative Cytogenetics, Vol 12, Iss 2, Pp 163-170 (2018)

Kingfishers comprise about 115 species of the family Alcedinidae, and are an interesting group for cytogenetic studies, for they are among birds with most heterogeneous karyotypes. However, cytogenetics knowledge in Kingfishers is extremely limited.

Autor: Ricardo José Gunski, Andrés Delgado Cañedo, Analía Del Valle Garnero, Mario Angel Ledesma, Nestor Coria, Diego Montalti, Tiago Marafiga Degrandi

Publikováno v: Comparative Cytogenetics, Vol 11, Iss 3, Pp 541-552 (2017)

Penguins are classified in the order Sphenisciformes into a single family, Spheniscidae. The genus Pygoscelis Wagler, 1832, is composed of three species, Pygoscelis antarcticus Forster, 1781, P. papua Forster, 1781 and P. adeliae Hombron & Jacquinot,

Publikováno v: Zoologischer Anzeiger - A Journal of Comparative Zoology. 254:1-7

Repetitive DNA varies in nature and abundance, and has had an important role in genome evolution of higher eukaryotes. In the present study we analyzed the dynamics of heterochromatic regions and telomeric sequences in three endemic South American ca

Karyotype morphology suggests that the Nyctibius griseus (Gmelin, 1789) carries an ancestral ZW-chromosome pair to the order Caprimulgiformes (Aves)

Comparative Cytogenetics 6(4): 379-387

Studies of karyotype have been revealing important information on the taxonomic relationships and evolutionary patterns in various groups of birds. However, the order Caprimulgiformes is one of the least known in terms of its cytotaxonomy. So far, th

Karyotypic characterization of Trachemys dorbigni (Testudines: Emydidae) and Chelonoidis (Geochelone) donosobarrosi (Testudines: Testudinidae), two species of Cryptodiran turtles from Argentina

We describe for the first time the karyotypes of two species of Cryptodiran turtles from Argentina, namely, Trachemys dorbigni (Emydidae) and Chelonoidis (Geochelone) donosobarrosi (Testudinidae). The karyotype of T. dorbigni (2n = 50) consists of 13
