The need of more rigorous assessments of marine species introductions: a counter example from the Brazilian coast.
Aplysina Nardo (Porifera, Verongida, Aplysinidae) from the Brazilian coast with description of eight new species
The authors' analyses revealed marked within individual variation for most species in characters associated to the spongin fibres, suggesting a low diagnostic strength for this set of characters in Aplysina.
Shallow-water Aplysina Nardo (Aplysinidae, Verongida, Demospongiae) from the São Sebastião Channel and its environs (Tropical southwestern Atlantic), with the description of a new species and a…
Two species of Aplysina Nardo, 1834 are described in this article, Aplysina caissara sp. n. and A. fulva (Pallas, 1766). Additionally, a possible third species was identified as A. aff. cauliformis.…
Trichoptera (Insecta) from Pernambuco State, northeastern Brazil
We present here the first list of species of Trichoptera (Insecta) from Pernambuco State, northeastern Brazil, as well as new records of caddisfly species for the country. This study is based on…
Cytotoxic alkylpiperidine alkaloids from the Brazilian marine sponge Pachychalina alcaloidifera.
Results support the hypothesis of a common biogenetic origin for the Haplosclerida bis-piperidine and bis- pyridine alkaloids.
Chemical variability within the marine sponge Aplysina fulva
New species of Radiospongilla (Porifera: Spongillidae) from Brazilian inland waters
A new species of Radiospongilla is described from 28 specimens collected between May 2007 to April 2010 from channels and ponds at the Aquaculture Station of Universidade Federal Rural de Pernambuco, Rio do Prata Basin, Recife, Pern Ambuco State, Brazil.
Freshwater Sponge Tubella variabilis Presents Richer Microbiota Than Marine Sponge Species
New information is presented on the composition of the microbial community found in freshwater spongees, which is diverse, abundant and distinct from some marine sponges, and the antimicrobial activity observed from the bacterial strains might play an important role in shaping microbial communities of the environment.
Clathria (Clathria) Schmidt, 1862 from Brazil with description of a new species and a review of records (Poecilosclerida: Demospongiae: Porifera).
The new species of Clathria (Clathria) differs from the other species by overall morphology and presence of auxiliary tylostrongyle megascleres.
Three new species of Tetilla Schmidt, 1868 (Tetillidae, Spirophorida, Demospongiae) from Bahia, northeastern Brazil
Three new species of Tetilla are described from stretches of the coast of Bahia, northeastern Brazil, all collected in shallow waters and soft bottoms, and one identification key to the Tetilla species occurring in the Atlantic Ocean is provided.
