Molecular Phylogeny of Cryptonanus (Didelphidae: Thylamyini): Evidence for a re...
Fegies, Ana Cláudia [UNESP]; Carmignotto, Ana Paula; Perez, Manolo Fernandez; Guilardi, Mariana Dias; Lessinger, Ana CláudiaMade available in DSpace on 2021-06-25T11:02:17Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-09-01; Systematic revisions of South American marsupials have contributed to our knowledge about genus and species diversity in the last decades, including studies of the most recently described genus Cryptonanus (Didelphidae), currently comprising four recognized species. Herein we provide the first phylogeny...
Interspecific genetic differences and historical demography in South American a...
Souza, Fernando Henrique Santos de; Perez, Manolo Fernandez; Bertollo, Luiz Antônio Carlos; Oliveira, Ezequiel Aguiar de; Lavoué, SébastienThe South American arowanas (Osteoglossiformes, Osteoglossidae, Osteoglossum) are emblematic species widely distributed in the Amazon and surrounding basins. Arowana species are under strong anthropogenic pressure as they are extensively exploited for ornamental and food purposes. Until now, limited genetic and cytogenetic information has been available, with only a few studies reporting to their genetic divers...
Historical demography and climate driven distributional changes in a widespread...
Oliveira, Ezequiel Aguiar de; Perez, Manolo Fernandez; Bertollo, Luiz Antônio Carlos; Gestich, Carla C.; Ráb, Petr; Ezaz, Tariq Tariq; Souza, F. H.S.The Neotropical region exhibits the greatest worldwide diversity and the diversification history of several clades is related to the puzzling geomorphologic and climatic history of this region. The freshwater Amazon ecoregion contains the main hydrographic basins of the Neotropical region that are highly dendritic and ecologically diverse. It contains a rich and endemic fish fauna, including one of its most ico...
Deciphering the evolutionary history of arowana fishes (Teleostei, osteoglossif...
Cioffi, Marcelo de Bello; Ráb, Petr; Ezaz, Tariq Tariq; Bertollo, Luiz Antônio Carlos; Lavoué, Sébastien; Oliveira, Ezequiel Aguiar de; Sember, AlexandrArowanas (Osteoglossinae) are charismatic freshwater fishes with six species and two genera (Osteoglossum and Scleropages) distributed in South America, Asia, and Australia. In an attempt to provide a better assessment of the processes shaping their evolution, we employed a set of cytogenetic and genomic approaches, including i) molecular cytogenetic analyses using C-and CMA3/DAPI staining, repetitive DNA mappi...
Estudo de estrutura genética da espécie de Cactácea colunar Pilosocereus machri...
Perez, Manolo FernandezUniversidade Federal de Minas Gerais; Pilosocereus machrisii is a columnar cacti with natural fragmented distribution; restrict to campos rupestres vegetation patches or rocky outcrops on the Cerrado domain; in Central and eastern Brazil. These features makes P. machrisii an appropriate biological model for population genetic studies aiming to gather information on population structure; since small and isolated...
