“…3). The sharing of fish species that have a relatively restricted distribution, such as L. weitzmani, between the uppermost tributaries of the São Francisco and Paraná rivers may be an evidence of historical relationships between these basins already proposed in previous studies (e.g., Ribeiro, 2006;Buckup, 2011;Camelier, Zanata, 2014). Unfortunately, tissue samples of the specimens from the rio São Francisco basin were not available for molecular analyses, thus the age of the split between these populations of L. weitzmani could not be estimated.…”

“…Furthermore, Glandulocaudini has an interesting distributional pattern, characterized by endemic species restricted to lowland areas along Brazilian coastal drainages and others endemic to upland areas of the Brazilian crystalline shield, in addition to species that are shared between both areas. This pattern was already used as example to explain or to propose biogeographic hypotheses (e.g., Buckup, 2011;Lima, Ribeiro, 2011;Camelier, Zanata, 2014;Ribeiro et al, 2016). Menezes et al (2008) reviewed the biogeography of the Glandulocaudini (former Glandulocaudinae), discussed some hypotheses, and suggested that additional molecular data should be used to test and better understand the evolutionary history of the group.…”

Although former studies on systematics and biogeography represent a progress on the knowledge of the tribe Glandulocaudini, none was grounded on molecular evidence. Thus, the first hypothesis of relationships for the tribe based on a multilocus analysis is presented, including all genera and most of the valid species. DNA sequences of Glandulocauda caerulea and Mimagoniates sylvicola were analyzed for the first time. A molecular clock analysis was used to estimate the origin of the Glandulocaudini and the approximate timing of cladogenetic events within the group. Glandulocaudini was recovered as monophyletic. No hypothesis recovered Glandulocauda as monophyletic, since G. melanopleura is sister to Lophiobrycon weitzmani while G. caerulea is closely related to Mimagoniates. The relationships within the latter genus were resolved. The molecular clock results indicate the origin of the Glandulocaudini during the Miocene with diversification in the group occurring from Neogene to Pleistocene. These results corroborated the hypothesis that its origin took place on the Brazilian crystalline shield with the subsequent occupation of the Atlantic Coastal drainages. Apparently, Pleistocene sea-level fluctuations might have shaped the distribution pattern of some species in Glandulocaudini.Keywords: Brazilian Crystalline Shield, Coastal Drainages, Molecular Clock, Molecular Systematics, Multilocus Analysis.Embora estudos prévios sobre sistemática e biogeografia representam um avanço no conhecimento da tribo Glandulocaudini, nenhum foi baseado em evidência molecular. Assim, a primeira hipótese de relações para a tribo com base em uma análise multilocus é apresentada, incluindo todos os gêneros e a maioria das espécies válidas. Sequências de DNA de Glandulocauda caerulea e Mimagoniates sylvicola foram analisadas pela primeira vez. Uma análise de relógio molecular foi utilizada para estimar a origem de Glandulocaudini e datas aproximadas de eventos cladogenéticos dentro do grupo. Glandulocaudini foi recuperada como monofilética. Nenhuma hipótese recuperou Glandulocauda como monofilético, uma vez que G. melanopleura é irmã de Lophiobrycon weitzmani e G. caerulea está proximamente relacionada a Mimagoniates. As relações dentro deste último gênero foram resolvidas. Os resultados do relógio molecular indicam que Glandulocaudini originouse durante o Mioceno, com diversificação dentro do grupo ocorrendo desde o Neogeno até o Pleistoceno. Estes resultados corroboram a hipótese da sua origem no escudo cristalino brasileiro, com a subsequente ocupação das drenagens costeiras atlânticas. Aparentemente, as flutuações pleistocênicas do nível do mar podem ter moldado o padrão de distribuição de algumas espécies em Glandulocaudini. Palavras-chave:

“…Those are presently limited to PAE (Parsimony Analysis of Endemicity), CADE (Cladistic Analysis of Distributions and Endemism), BPA (Brooks Parsimony Analysis) and BPA 0 . Those four methods have been applied with some degree of success and their results have been shown to contain a reasonable degree of biogeographic coherence (Hubert, Renno, 2006;Ingenito, Buckup, 2007;Buckup, 2011;Lima, Ribeiro, 2011;Schaefer, 2011;Camelier, Zanata, 2014;Matamoros et al, 2015). The use of other methods such as 3-area analysis (Nelson, Ladiges, 1991), reconciled tree analysis (Page, 1994a,b), component analysis (Nelson, Platnick, 1981) and paralogy-free subtrees (Nelson, Ladiges, 1996) would be interesting in theory, but we found that software available for their implementation cannot be reliably applied to our database, which is probably one of the largest yet assembled for any biogeographic problem.…”

“…Nonetheless, it has been widely employed in the biogeography of neotropical fishes (cf. Hubert, Renno, 2006;Ingenito, Buckup, 2007;López et al, 2008;Buckup, 2011;Lima, Ribeiro, 2011;Schaefer, 2011). It seems certain that PAE is not efficient in recovering area relationships, since it does not utilize evolutionary data in any form.…”

Biogeography of Amazonian fishes: deconstructing river basins as biogeographic units

Biogeography of Amazonian fishes (2,500 species in vastly disjunct lineages) is complex and has so far been approached only partially. Here, we tackle the problem on the basis of the largest database yet on geographical distribution and phylogenetic relationships of Amazonian fishes, including all information available. Distributions of 4,095 species (both Amazonian and outgroups) and 84 phylogenetic hypotheses (comprising 549 phylogenetically-informative nodes) were compiled, qualified and plotted onto 46 areas (29 Amazonian and 17 non-Amazonian). The database was analyzed with PAE, CADE, BPA and BPA 0 , yielding largely congruent results and indicating that biogeographic signal is detectable on multiple dimensions of fish distribution, from single species ranges to cladistic congruence. Agreement is especially pronounced in deeper components, such as Trans-Andean, Cis-Andean, Western Amazon and Orinoco basins. Results show that all major Amazonian tributaries, as well as the Amazon basin itself, are non-monophyletic and constitute hybrid sets of heterogeneous biotic partitions. Amazonian drainages should not be assumed a priori as historically cohesive areas, contrary to widespread practice. Our hypothesis allows reevaluation of broader issues in historical biogeography, such as the predictive power of biogeographic hypotheses, the vicariant/ dispersal duality, the significance of widely distributed taxa, and the need for temporal dimension in biogeographic patterns. A biogeografia dos peixes amazônicos (2.500 espécies de diferentes linhagens) é complexa e até agora foi abordada apenas parcialmente. Aqui abordamos o problema com base no maior banco de dados já feito sobre a distribuição geográfica e as relações filogenéticas dos peixes amazônicos, incluindo todas as informações disponíveis. A distribuição de 4.095 espécies (tanto amazônicas como de grupos-externos) e 84 hipóteses filogenéticas (que incluíam 549 nós filogeneticamente informativos) foram compiladas e qualificadas em 46 áreas (29 amazônicas e 17 não-amazônicas). O banco de dados foi analisado a partir das metodologias PAE, CADE, BPA e BPA0, resultando em topologias amplamente congruentes e indicando que o sinal biogeográfico é detectável em múltiplas dimensões, desde a simples distribuição de peixes até em congruência cladística. A concordância topológica é especialmente pronunciada em componentes mais profundos, como as bacias Trans-Andina, Cis-Andina, Amazonas Ocidental e Orinoco. Os resultados demonstram que todos os principais afluentes amazônicos, bem como a própria bacia amazônica, não são monofiléticos e constituem conjuntos híbridos formados a partir de parcelas bióticas heterogêneas. As drenagens amazônicas não devem ser consideradas a priori como áreas historicamente coesas, contrariamente à prática generalizada. Nossa hipótese permite a reavaliação de questões mais amplas na biogeografia histórica, como o poder preditivo de hipóteses biogeográficas, a dualidade vicariante/dispersão, significância de táxons amplamente distribuídos e a n...

This study aims to provide a list of fish species from the Igaraçu River and some lakes of the lower Parnaíba River, Delta do Parnaíba, northeastern state of Piauí, Brazil. Eleven collecting points were sampled in a coastal area, in a wind farm, during the dry season in November 2011. A total of 1,023 individuals of 24 species, 13 families and 6 orders were collected. The most representative families in number of species were Characidae, Cichlidae and Curimatidae, respectively. Astyanax aff. bimaculatus, Serrapinnus piaba and Psellogrammus kennedyi presented the greatest abundance and distribution among the sampling points. Oreochromis niloticus was the only alien species captured. No fishes were captured in five sampling sites. Voucher material is deposited in a new zoological collection, “Coleção Zoológica do Delta do Parnaíba”.
