Phylogenetic relationships between Oplophoridae, Atyidae, Pasiphaeidae, Alvinocarididae Fam. N., Bresiliidae, Psalidopodidae and Disciadidae (Crustacea caridea atyoidea)
TLDR
A seguinte classificacao filogenetica sequenciada e proposta: Superfamilia Atyoidea; Familia Oplophoridae; Familias Atyidae; Subfamilia Xiphocaridinae; GeneroXiphocaris; Subfamily Atyinae ; Familia Pasiphaeidae;fam.n. Expand
Rhodolith beds at the easternmost extreme of South America: Community structure of an endangered environment
TLDR
Phytobenthic communities associated with subtidal rhodolith beds in northeastern Brazil are described and the hypothesis that depth affects their structure is tested, finding that when depth and water transparency increased, the number of species and the abundance of macroalgae decreased. Expand
PHYLOGENETIC RELATIONSHIPS OF HIPPOLYTID GENERA, WITH AN ASSIGNMENT OF NEW FAMILIES FOR THE CRANGONOIDEA AND ALPHEOIDEA (CRUSTACEA, DECAPODA, CARIDEA)
TLDR
The traditional practice of naming monotypic taxa of suprageneric level has been avoided, yet all genealogical information indicated in the cladogram can be retrieved from the final classification proposed here for the Crangonoidea and Alpheoidea. Expand
Bioecology of the Ghost Crab Ocypode quadrata (Fabricius, 1787) (Crustacea: Brachyura) Compared with Other Intertidal Crabs in the Southwestern Atlantic
TLDR
Ghost crabs provide an alternative source of food for the ground-burrowing owl, a predator that may represent an important population controlling factor, other than the human-induced impacts on sandy beaches, according to researchers from subtropical Praia Brava, Itajaí, Santa Catarina. Expand
Population biology of Callinectes danae and Callinectes sapidus (Crustacea: Brachyura: Portunidae) in the south-western Atlantic
TLDR
In both species, a tendency was observed for the egg mass to increase with size of females, and the capture per unit of effort presented the lowest values in summer, while the largest values occurred from March, August and November. Expand
Distribution of warm water alpheoid shrimp (Crustacea, Caridea) on the continental shelf of eastern South America between 23 and 35º Lat. S
TLDR
The southern boundaries of Tozeuma serratum A. Milne Edwards, Salmoneus ortmanni (Rankin) and Processa profunda Manning & Chace have been extended to Sao Paulo, Parana and Uruguay, and Latreutes parvulus (Stimpson), previously not known beyond Sao Paulo has been found to as far south as the Province of Buenos Aires. Expand
A cladistic approach to relationships in pentastomida.
TLDR
This phylogenetic system is largely congruent with the first modern taxonomic arrangement proposed for the Pentastomida, and the internal relationships among the pentastomid subgroups have received much less attention in the past. Expand
A catalogue of Helobdella (Annelida, Clitellata, Hirudinea, Glossiphoniidae), with a summary of leech diversity, from South America
TLDR
This is the first reassessment of South American Helobdella in 27 years and a dominant feature of the South American leech fauna is the presence of many terrestrial predaceous forms. Expand
Morphological support for the phylogenetic positioning of Pentastomida and related fossils
TLDR
The results indicate that Pentastomida is a transitional group between the Arthropoda and some of the Nemathelminth groups such as Nematoda and Nematomorpha. Expand
Polychaeta, Annelida, and Articulata are not monophyletic: articulating the Metameria (Metazoa, Coelomata)
TLDR
Annelida and Polychaeta are non-monophyletic, even when including Echiura, Clitellata, and Pogonophora, and Articulata; and Owenia plus Enterocoela form a monophyletics group related to the tubicolous polychaetes. Expand
