1. Sexual and reproductive traits of the pearl oyster shrimp Pontonia margarita (Decapoda: Palemonidae), symbiotically inhabiting the mantle cavity of the rugose pen shell Pinna rugosa (Bivalvia: Pinnidae)
ABSTRACT Symbiosis between decapods and mollusks provides a unique opportunity to examine some of the evolutionary strategies employed by marine invertebrates. We describe the sexual and reproductive traits of the pearl oyster shrimp, Pontonia margarita Verril, 1869, found symbiotically inhabiting the mantle cavity of the rugose pen shell, Pinna rugosa Sower

2. Diversity of coastal mysids from Pulau Tinggi, Sultan Iskandar Marine Park, Malaysia
ABSTRACT A checklist of the order Mysida from Pulau Tinggi, Sultan Iskandar Marine Park, Johor, Malaysia is presented. With the aid of an epibenthic sledge, a total number of 9,239 mysids were collected during years 2012-2013 from two fixed stations of seagrass bed in Pulau Tinggi. So far there are 13 species, 10 genera, and 6 subfamilies of mysids. Of these

3. Composition and abundance of decapod crustaceans in mixed seagrass meadows in the Paraguaná Peninsula, Venezuela
ABSTRACT Thalassia testudinum and Halodule wrigthii are the dominant seagrasses in the Caribbean, being common across shallow shorelines, either as monospecific or as intermixed meadows. Among the macrofauna associated with these beds, crustaceans are considered essential for the whole ecosystem functioning. However, knowledge about the associated community

4. Pedological Studies of Subaqueous Soils as a Contribution to the Protection of Seagrass Meadows in Brazil
ABSTRACT: Seagrass meadows are considered one of the most important and valuable ecosystems on the planet, but also one of the most threatened. Missing knowledge about their existence and their subtidal nature are the main reasons for the lack of information about seagrass soils, especially in Brazil and other tropical areas. This study discussed the paradox

5. Seagrass and Submerged Aquatic Vegetation (VAS) Habitats off the Coast of Brazil: state of knowledge, conservation and main threats
Resumo Pradarias de gramas marinhas e vegetação aquática submersa (VAS) estão entre os ecossistemas mais ameaçados do planeta, gerando preocupação sobre o equilíbrio dos ecossistemas costeiros e a sustentabilidade das pescarias. A presente revisão avaliou o estado do conhecimento sobre as pradarias marinhas e VAS do Brasil, considerando as respostas

6. Habitat selection of the pink shrimp Farfantepenaeus paulensis and the blue crab Callinectes sapidus in an estuary in southern Brazil: influence of salinity and submerged seagrass meadows
This study was conducted in two estuarine inlets (Saco da Mangueira and Saco do Arraial) at the Patos Lagoon estuary, southern Brazil. The changes in relative abundance and size of post-larvae and juvenile shrimp Farfantepenaeus paulensis and juvenile blue crab Callinectes sapidus were compared, considering the influence of salinity and the presence of subme

7. Quantification and classification of the main environmental impacts on a Halodule wrightii seagrass meadow on a tropical island in northeastern Brazil
Múltiplos mecanismos estressores têm causado em todo mundo declínio das angiospermas marinhas, que são vulneráveis a pressões ambientais e/ou antrópicas. A perda de prados de Halodule wrightii tem sido relatada para o litoral da Ilha de Itamaracá (Nordeste do Brasil). O presente estudo identificou os principais fatores antrópicos que influenciaram n

8. Projeto raia de fogo: aspectos populacionais da raia de fogo (Dasyatis marianae Gomes, Rosa &Gadig, 2000) e pesca de elasmobrânquios no complexo recifal do Parracho de Maracajaú
The species Dasyatis marianae inhabits coastal areas associated with coral reefs, considered endemic to the northeast of Brazil, occurring from the State of Maranhão to the south of Bahia. Specimens of this species are commonly sighted by divers and fishermen in the area of Maracajaú reefs, a complex reef that is part of the Environmental Protection Area o

9. Biological activities of the sulfated polysaccharide from the vascular plant Halodule wrightii
A sulfated polysaccharide (SPSG) was successfully isolated from seagrass Halodule wrightii Asch., Cymodoceaceae, and its antioxidant and anticoagulant activities were investigated. The data presented here showed that the SPSG is a 11 kDa sulfated heterogalactan with a sulfatation degree of 20.63% and it also contains glucose and xylose. SPSG antioxidant acti

10. Spatial and temporal structure of fish assemblages in a hyperhaline coastal system: Ría Lagartos, Mexico
The spatial and temporal fish species assemblages were analyzed throughout two annual cycles (2004-2005 and 2007-2008) in the Ría Lagartos Lagoon system, Mexico, via non-parametric multivariate analyses. We compared density and biomass of fish species among five habitat types defined by combinations of structure and environmental characteristics (hyperhalin

11. Small scale change in mollusk diversity along a depth gradient in a seagrass bed off Cabo Frio, (Southeast Brazil)
Há pouco conhecimento sobre a comunidade animal em bancos de fanerógamas marinhas no Atlântico sudeste. O presente estudo teve como objetivo caracterizar e quantificar assembléias de Mollusca nesses habitats únicos, utilizando uma escala espacial sensível suficiente para relacionar mudança na estrutura da assembléia aos gradientes em exposição ao a
