Mantle margin morphogenesis in Nodipecten nodosus (Mollusca: Bivalvia): new insights into the development and the roles of bivalve pallial folds
TLDR
Analysis of the mantle margin of the scallop Nodipecten nodosus shows that the middle mantle fold forms from the outer surface of the inner fold after metamorphosis and that the initial unfolded mantle margin may represent a common condition among bivalves. Expand
A new species of pentastomida infecting Tropidurus hispidus (Squamata: Tropiduridae) from Caatinga in Northeastern Brazil.
TLDR
A new species of Brazilian Raillietiella Sambon, 1910 from lungs of Tropidurus hispidus is described, with the dimensions of sharp hooks and strongly curved or "C-shaped" male copulatory spicules with knob-like posterior projection from the base towards the inner curvature of the spicule. Expand
Evaluating the taxonomic identity in four species of the lobose testate amoebae genus Arcella Ehrenberg, 1832
TLDR
In the present survey, the morphology, biometry and ecology of 2400 individuals in the genus Arcella Ehrenberg, 1832, collected from the Tiete River in Sao Paulo, Brazil are examined and 4 distinct taxa are determined, each of them encompassing a number of other non-distinct nominal taxa. Expand
Prevalence and intensity of pentastomid infection in two species of snakes from northeastern Brazil.
TLDR
These are the first data on pentastomid infection in snakes in Northeastern Brazil and both snake species comprise new host records for thepentastomids, indicating that the generalist parasites C. tetrapoda and R. furcocerca share their definitive hosts. Expand
Ultra-structure and Biometry of Three Lobose Testate Amoebae of the Family Lesquereusiidae (Tubulinea: Arcellinida) Based on Specimens from Sao Paulo, Brazil
The family Lesquereusiidae is characterized by the presence of endogenous siliceous particles aggregated to the test. This paper redescribes three species in the family, namely: Netzelia wailesiExpand
Distribution of wood-boring bivalves in the Mamanguape River estuary, Paraíba, Brazil
Wood-boring bivalves of the families Teredinidae and Pholadidae are reported for the first time in Paraíba State, north-east Brazil. During one year, molluscs were collected from mangrove tree logsExpand
The interference of methods in the collection of teredinids (Mollusca, Bivalvia) in mangrove habitats
TLDR
In the estuary of the Mamanguape River (Paraiba, Brazil), a new collection technique was developed and applied with virgin poles of mangrove trees Avicennia schaueriana, Rhizophora mangle, and Laguncularia racemosa, taking into account wood preference, water salinity and depth influence during teredinid larval settlement. Expand
Morphology, Biometry, Ecology and Biogeography of Five Species of Difflugia Leclerc, 1815 (Arcellinida: Difflugiidae), from Tiete River, Brazil
TLDR
The biometrical measures and analysis based on a large number of individuals shows that natural populations of testate amoebae may be highly variable. Expand
Taxonomic Identity in Microbial Eukaryotes: A Practical Approach Using the Testate Amoeba Centropyxis to Resolve Conflicts Between Old and New Taxonomic Descriptions
TLDR
This work examined the morphology, biometry, and ecology of 2,120 Centropyxis individuals collected from Tiete River, Sao Paulo, Brazil, and suggested an explicit and objective taxonomic practice in order to enhance the taxonomic and species concepts for microbial eukaryotes. Expand
