| RESUMO As descargas de água doce permanentes em praias arenosas, conhecidas como sangradouros, promovem alterações em diferentes escalas espaciais e temporais sobre as características ambientais, e consequentemente sobre as populações macrobentônicas. O objetivo deste estudo foi avaliar as alterações da abundância, distribuição e estrutura populacional do isópode Tholozodium rhombofrontalis (Giambiagi, 1922) em um sangradouro permanente. Coletas sazonais foram realizadas na praia de Barrancos, cidade de Pontal do Paraná, estado do Paraná, sul do Brasil, em três locais: sangradouro (dentro do sangradouro), intermediário (a 30 m de distância do sangradouro) e distante (a 150 m de distância do sangradouro), durante as quatro estações dos anos de 2012 e 2013.... |

| Besouros da família Staphylinidae são comuns em zonas costeiras inundáveis pelas marés, como praias arenosas, manguezais, estuários e marismas. O objetivo desse trabalho foi estudar a distribuição espacial e a variação temporal da abundância ao longo de um ano, das espécies ocorrentes em duas praias arenosas (Assenodi e Cem) no Pontal do Paraná, Paraná, Brasil. Coletas semanais com um cilindro de PVC com 15 cm de diâmetro (0,017 m²) enterrado a 5 cm de profundidade, foram realizadas de janeiro a dezembro de 2012. A praia Assenodi apresentou altos valores de umidade de sedimento no supralitoral e pós-praia. Nesta praia, Bledius bonariensis foi dominante, mas também houve registro de B. fernandezi, ambas distribuídas nas porções superiores do perfil praial e... |

| Swimming crabs are commonly found in the otter-trawl shrimp fishery by-catch, which operate intensively in the Coastal Plain of Leste Beach, where is located Shangri-lá Beach (25°37'30"S and 48°25'08"W), Paraná State. This work aimed to study the population structure of Callinectes ornatus Ordway, 1863, the most abundant swimming crab in this beach. Between March 2000 and April 2001, fortnightly visits were accomplished in Shangri-lá at the fish market, where all swimming crabs of one otter-trawl were collected. The following data from each individual of C. ornatus were obtained: sex, carapace width (excluding lateral spines), weight, and the gonadal maturation stage, based on its color and size. Juveniles and mature males were dominant, mean sexual... |

| Nesta nota são apresentadas as principais características do hábictat de Diglotta brasiliensis Caron & Ribeiro-Costa, 2008, uma espécie recentemente descrita para a região Neotropical. Os indivíduos foram encontrados habitando uma faixa de aproximadamente 4 m de largura da zona intermareal superior de duas praias estuarinas (ambas localizadas no setor euhalino da baía), com as suas densidades variando de 13 a 80 indivíduos/m². Nesta faixa da praia os sedimentos estiveram compostos de areia média moderadamente a muito bem selecionada e com teor de umidade em torno de 6,5%. O teor de matéria orgânica e de carbonato de cálcio do sedimento variou entre 0,08 a 0,13% e 3,4 a 5,4%, respectivamente. Nesses locais, D. brasiliensis foi encontrada coexistindo... |

| The distribution, population dynamics and secondary production of the polychaete Euzonus furciferus was studied in Atami Beach (Southern Brazil), from February 1992 to March 1993. Euzonus furciferus Ehlers, 1897 is the only deposit feeder species of the upper intertidal region. The organisms were present in the sandy beach all over the year, concentrated in a narrow band, and reaching maximal densities of 3,029 individuals m-2. Peaks of abundance occurred in September 1992, with a mean of 681.8 individuals m-2. Recruitment occurred in winter, with a peak in July. Mean annual biomass was estimated in 0.218 gAFDW m-2, with a total annual production of 0.466 gAFDW m-2 y-1, giving a P/B ratio of 2.13 y-1. Similar values were found for a filter-feeder... |

| Mysidacea are common sublittoral crustaceans that inhabit all coasts in the world. In this study, the population characteristics and the reproductive biology of Metamysidopsis neritica Bond-Buckup & Tavares, 1992 were studied in the surf zone of a south Brazilian beach (Atami). Mysids were sampled at monthly intervals from August, 1999 to July, 2000 (total of 29,490 individuals). Individuals were classified into six population categories. The highest abundance occurred in May (8,665) and August (6,415), and lowest in September (336) and December (368). Three main generations were identified, namely the summer, fall and winter generations. The winter generation was the longest (four to five months). The fall generation lasted four months, and the... |

| The reproductive cycle of the irregular echinoid Mellita quinquiesperforata (Leske, 1778) was studied in populations from two sand beaches with different morphodynamic conditions in Parana coast, from February 1992 through July 1994. Gametogenesis was described by histological and gonad index methods and the differences between both populations were observed in the extension of nutrient storage and spawning period. Both populations exhibited a main reproductive period during spring/summer and a nutrient storage period during autumn/winter months. The spawning period at the intermediate-dissipative beach was shorter than at the reflective beach. Meanwhile, a nutrient storage stage was more extensive in the latter. Gonad index varied between both sexes and... |

| Ocean rocky formations are known as islands. When islands become completely submerged, they are called stone slabs. Like reefs, these formations alter the flux of water produced by the waves, which in turn interacts with the adjacent sediment, altering the sediment and its undulation marks. The alterations caused by the interaction between the waves and emerged or submerged rigid structures can potentially alter the composition and the distributional patterns of the infauna of the adjacent, unconsolidated substrate. In order to evaluate the strength of these alterations, we sampled the infauna and the sediment adjacent to two ocean structures, one emerged and one submerged. Collecting was performed in winter and summer, while discriminating between the... |
