1. Ecologia e Conservação de Tartarugas Marinhas Através da Análise de Encalhes no Litoral Paraibano
Five sea turtle species use the Brazilian coast for reproduction and feeding: loggerhead turtle (Caretta caretta), green turtle (Chelonia mydas), leatherback turtle (Dermochelys coriacea), olive turtle (Lepidochelys olivacea) and hawksbill turtle (Eretmochelys imbricata). These species are included in the threatened categories, as much globally, according to

2. Fenologia, ecologia da polinizaÃÃo e reproduÃÃo de espÃcies de manguezal, no municÃpio de Goiana - PE
The mangal is a tropical ecosystem of the coastal and estuarine areas, and it is important to shelter the marine animals and for its reproduction, beside promote the increase of productivity of neighbor community. Its vegetation, the mangrove, is composed of a few species with proper feature, such as viviparity and aerial roots associated with breath. There

4. Gametogênese e desenvolvimento embrionário de Nausithoe aurea (Scyphozoa, Coronatae) do canal de São Sebastião - SP. / Gametogenesis and embryonic development of Nausithoe aurea (Scyphozoa, Coronatae) from the São Sebastião Channel - SP.
Nausithoe aurea Silveira &Morandini, 1997 é uma espécie metagenética e dióica com fecundação externa. Os oócitos são liberados continuamente (55 dias em laboratório), porém com grandes variações no número a cada dia. No desenvolvimento embrionário a clivagem, após o estágio de 8 células, passa de holoblástica e igual para pseudoespiral. A g

5. Hitchhiking behaviour in the obligatory upstream migration of amphidromous snails
Migratory animals endure high stress during long-distance travel in order to benefit from spatio-temporally fluctuating resources, including food and shelter or from colonization of unoccupied habitats. Along with some fishes and shrimps, nerite snails in tropical to temperate freshwater systems are examples of amphidromous animals that migrate upstream for

6. Inducible morphology, heterochrony, and size hierarchies in a colonial invertebrate monoculture.
Conditional or inducible strategies are a powerful tool for analyzing the evolution of aggressive behavior. Structures such as stolons and nematocyst-laden tentacles, induced to deter encroachment by competitors, are proportionately better represented in clonal and colonial marine invertebrates than in aclonal animals. Stolons can be produced by colonies of
