Phylogenetic Assessment of Freshwater Mussels <i>Castalia ambigua</i> and <i>C. inflata</i> at an Ecotone in the Paraguay River Basin, Brazil Shows That Inflated and Compressed She... by Miluska Olivera-Hyde, Eric Hallerman, Rogério Santos, Jess Jones, Brianne Varnerin, Guilherme da Cruz Santos Neto, Maria Cristina Mansur, Priscilla Moraleco, Claudia Callil

“…Our results collectively suggest that: (1) “<i>C. ambigua</i>”, “<i>C. inflata</i>”, and morphologically intermediate individuals within the upper Paraguay drainage represent one phylogenetic lineage, (2) a phylogeographic divide exists between <i>Castalia</i> populations occurring in the Paraguay and Amazon River basins, and (3) the evolutionary and taxonomic uncertainties that we have identified among <i>Castalia</i> species should be thoroughly assessed across their distribution using both morphological and molecular characters.…”

A survey of necrophagous blowflies (Diptera: Oestroidea) in the Amazonas-Negro interfluvial region (Brazilian Amazon) by Eduardo Amat, Marco Antonio Tonus Marinho, José Albertino Rafael

“…Comparison among sampled sites revealed no considerable variation in fauna composition, except for the species Eumesembrinella benoisti (Séguy 1925) and Hemilucilia sp., whose occurrence was observed only in a single locality. Apparently, Amazon rivers are not efficient geographical barriers to influence the current composition of necrophagous blowfly assemblages. …”

Multiloci analyses suggest synonymy among Rhomboplites, Ocyurus and Lutjanus and reveal the phylogenetic position of Lutjanus alexandrei (Lutjanidae: Perciformes) by Ivana Veneza, Raimundo da Silva, Danillo da Silva, Grazielle Gomes, Iracilda Sampaio, Horacio Schneider

“…For the dating of L. alexandrei, another nucleotide dataset (3.0 kb; 40 species) validated the genetic identity of this species that diverged from the sister taxon L. apodus between 2.5 - 6.5 Mya, probably as a result of the barrier caused by the muddy outflow from Orinoco and Amazon rivers along the coastal zone. This report is the most robust multiloci analysis to confirm the synonymy of the three genera of Lutjaninae from Western Atlantic and the first reliable inference about the phylogenetic relationships and origin of L. alexandrei.…”
