Chromosomal analysis in Crotophaga ani (Aves, Cuculiformes) reveals extensive genomic reorganization and an unusual Z-Autosome Robertsonian translocationn
Kretschmer, Rafael; Gunski, Ricardo José; Garnero, Analía del Valle; Freitas, Thales Renato Ochotorena de; Toma, Gustavo Akira; Cioffi, Marcelo de Bello; Oliveira, Edivaldo Herculano Corrêa; O’Connor, Rebecca E.; Griffin, Darren K. (2021) [Artigo de periódico]Although cytogenetics studies in cuckoos (Aves, Cuculiformes) have demonstrated an interesting karyotype variation, such as variations in the chromosome morphology and diploid number, their chromosome organization and ... -
Chromosomal polymorphism and comparative chromosome painting in the rufous-collared sparrow (Zonotrichia capensis)
Bulau, Sandra Eloisa; Kretschmer, Rafael; Gunski, Ricardo José; Garnero, Analía del Valle; O’Brien, Patricia C.M.; Smith, Malcolm A. Fergunson; Oliveira, Edivaldo Herculano Corrêa; Freitas, Thales Renato Ochotorena de (2018) [Artigo de periódico]Zonotrichia capensis is widely distributed in the Neotropics. Previous cytogenetic studies demonstrated the presence of polymorphisms in two chromosome pairs (ZCA2 and ZCA4). Here, we report results based on comparative ... -
A Comprehensive Cytogenetic Analysis of Several Members of the Family Columbidae (Aves, Columbiformes)
Kretschmer, Rafael; Furo, Ivanete de Oliveira; Gomes, Anderson José Baia; Kiazim, Lucas Gem; Gunski, Ricardo José; Garnero, Analía del Valle; Pereira, Jorge C.; Smith, Malcolm A. Fergunson; Oliveira, Edivaldo Herculano Corrêa; Griffin, Darren K.; Freitas, Thales Renato Ochotorena de; O’Connor, Rebecca E. (2020) [Artigo de periódico]The Columbidae species (Aves, Columbiformes) show considerable variation in their diploid numbers (2n = 68–86), but there is limited understanding of the events that shaped the extant karyotypes. Hence, we performed whole ... -
Descripción cariotípica de Spheniscus magellanicus (Spheniscidae)
Ledesma, Mario A.; Freitas, Thales Renato Ochotorena de; Silva, Juliana da; Silva, Fernanda Rabaioli da; Gunski, Ricardo José (2003) [Artigo de periódico]En este trabajo se describe por primera vez el cariotipo y el patrón de bandas C de Spheniscus magellanicus. Se tomaron muestras de sangre periférica de tres hembras y cuatro machos en Imbé (Rio Grande do Sul, Brasil). ... -
Interspecies chromosome mapping in Caprimulgiformes, Piciformes, Suliformes, and Trogoniformes (Aves): cytogenomic insight into microchromosome organization and karyotype evolution in birds
Kretschmer, Rafael; Souza, Marcelo Santos de; Furo, Ivanete de Oliveira; Michael N. Romanov; Gunski, Ricardo José; Garnero, Analía del Valle; Freitas, Thales Renato Ochotorena de; Oliveira, Edivaldo Herculano Corrêa; O’Connor, Rebecca E.; Griffin, Darren K. (2021) [Artigo de periódico]Interchromosomal rearrangements involving microchromosomes are rare events in birds. To date, they have been found mostly in Psittaciformes, Falconiformes, and Cuculiformes, although only a few orders have been analyzed. ... -
Novel insights into chromosome evolution of Charadriiformes: extensive genomic reshuffling in the wattled jacana (Jacana jacana, Charadriiformes, Jacanidae)
Kretschmer, Rafael; Souza, Marcelo Santos de; Barcellos, Suziane Alves; Degrandi, Tiago Marafiga; Pereira, Jorge C.; O’Brien, Patricia C.M.; Smith, Malcolm A. Fergunson; Gunski, Ricardo José; Garnero, Analía del Valle; Oliveira, Edivaldo Herculano Corrêa; Freitas, Thales Renato Ochotorena de (2020) [Artigo de periódico]The order Charadriiformes comprises three major clades: Lari and Scolopaci as sister group to Charadrii. Until now, only three Charadriiformes species have been studied by chromosome painting: Larus argentatus (Lari), ... -
Repetitive DNAs and shrink genomes: a chromosomal analysis in nine Columbidae species (Aves, Columbiformes)
Kretschmer, Rafael; Oliveira, Thays Duarte de; Furo, Ivanete de Oliveira; Silva, Fabio Augusto Oliveira; Gunski, Ricardo José; Garnero, Analía del Valle; Cioffi, Marcelo de Bello; Oliveira, Edivaldo Herculano Corrêa; Freitas, Thales Renato Ochotorena de (2018) [Artigo de periódico]An extensive karyotype variation is found among species belonging to the Columbidae family of birds (Columbiformes), both in diploid number and chromosomal morphology. Although clusters of repetitive DNA sequences play an ...
