Abstract Seaports are introduction hotspots for invasive alien species (IAS). This is especially true rodents, which have accompanied humans around the globe since earliest days of ocean-going voyages. The rapid spread IAS soon after arrival in a new environment facilitated by further human-mediated transport or landscape features, like roads. By measuring genetic diversity and structure to investigate dispersal pathways, we gained insight into transport, establishment stages biological...
The large amphibian genomes contain numerous repetitive DNA components that have played an important role in the karyotypic diversification of this vertebrate group. Hypotheses based on presumable primitive karyotype (2n = 20) anurans family Pipidae suggest they evolved principally through intrachromosomal rearrangements. Pipa is only South American pipid, while all other genera are found Africa. divergence lineages from African ones occurred at least 136 million years ago and thought to had...
The genus Rhinella is one of the most diverse groups bufonid toads, currently composed by 93 valid species and naturally distributed throughout different Neotropical ecoregions. Here, we analyze nine Brazilian populations toads representing margaritifera marina groups. These new data include first description R. hoogmoedi proboscidae karyotypes, as well other taxonomically unresolved forms. Chromosomal analysis revealed pronounced chromosomal uniformity (2n=22), including diploid number...
Kingfishers comprise about 115 species of the family Alcedinidae, and are an interesting group for cytogenetic studies, they among birds with most heterogeneous karyotypes. However, cytogenetics knowledge in is extremely limited. Thus, aim this study was to describe karyotype structure Ringed Kingfisher ( Megaceryletorquata Linnaeus, 1766) Green Chloroceryleamericana Gmelin, 1788) also compare them related order identify chromosomal rearrangements. The presented 2n = 84 had 94. increase...
O gênero Akodon é um dos mais diversificados da América do Sul, com 41 espécies reconhecidas, e se distribui ao longo de todo o continente, indo Colômbia até a Argentina. As desse são morfologicamente muito similares, por isso citogenética uma ferramenta chave para identificação específica. objeto deste estudo, espécie A. montensis, possui cariótipo padrão 2n=24 NA=42. De modo geral conjunto cromossômico deve manter constante fim evitar erros na formação gametas garantir assim viabilidade...
Neste trabalho didático, é apresentada uma alternativa para o ensino das alterações cromossômicas numéricas, as aneuploidias. A atividade proposta na forma de um jogo cujas cartas, contendo cromossomos são combinadas aos pares durante a montagem do cariótipo, originando assim diferentes Além proporcionar momento descontração, também favorece participação ativa dos alunos construção conhecimento e no desenvolvimento estratégias dinamizar aplicação.
