An analysis of the population structure of the tanaid Sinelobus cf. stanfordi was performed at Pinheiros River mangrove, Guaratuba Bay, Paraná State, southern Brazil (25°49′S 48°34′W). Fifteen samples of 12 × 12 cm were obtained bimonthly from the surface of galleries (interconnected burrow complex) constructed by the adult mangrove crab Ucides cordatus from June 2007 to April 2008. The carapace length (CL) of a total of 714 tanaids was measured. Tanaids were divided into four demographic categories: males (M), ovigerous females (OV), preparatory females (PREP) and non-reproductive individuals (NREP) with a mean CL of 0.55, 0.49, 0.48 and 0.43 mm, respectively. In the NREP group, specimens smaller than 0.32 mm were classified as juveniles. NREP predominated in all sampling months, and among sexually mature individuals, a strong predominance of females was observed throughout the study period. Temporal fluctuations in abundance were observed, with a peak in August 2007. The reproductive period of this species is continuous, with a peak in the summer, like most S. cf. stanfordi populations.
Coleções científicas são fundamentais aos estudos da biodiversidade e desde 2014, o “Instituto de Estudos do Mar Almirante Paulo Moreira (IEAPM)” mantém um acervo científico dedicado aos organismos bentônicos e incrustantes, objetivando garantir informações para as linhas de pesquisa relacionadas a Taxonomia/Sistemática, Filogeografia, Biogeografia e Bioinvasão. No momento, a coleção científica contém cerca de 1.200 espécimes dos principais grupos taxonômicos bentônicos, como Algae, Porifera, Cnidaria, Polychaeta, Mollusca, Crustacea, Bryozoa, Ascidiacea, além de uma coleção de tecidos. Os moluscos são a parte mais representativa do acervo, correspondendo a aproximadamente 32%,especialmente Gastropoda e Bivalvia, com destaque para as famílias Mytilidae, Ostreidae, Vermetidae e Calyptraeidae. A Coleção Científica do IEAPM representa um importante panorama da biodiversidade marinha, principalmente para o Estado do Rio de Janeiro.
