Sharks are very sensitive to stress and prone to a high mortality rate after capture. Since approximately 50 million of sharks are caught as bycatch every year, and current recommendations to reduce the impact of commercial fishing strongly support immediate release, it is imperative to better understand post-release mortality caused by the stress of capture and handling. Blood samples allow the assessment of stress levels which are valuable tools to reduce mortality in commercial, recreational and scientific fishing, being essential for the improvement in those conservation measures. Biochemical analyses are widely used for sharks as stress indicators, with secondary plasma parameters (lactate, glucose and ions) being the most often employed assays. However, it is virtually impossible to determine baseline plasma parameters in free-ranging sharks, since blood withdrawal involves animal capture and restrain, which are stressful procedures. This study aims at analyzing secondary parameters of five healthy tiger sharks captured with circular hooks and handlines in Fernando de Noronha (Northeastern Brazil) and comparing them with secondary parameters of three dead tiger sharks caught off Recife (also Northeastern Brazil). The results showed that the analysis of some plasma constituents in dead animals may be an efficient tool to assess stress and lethality. However, traditional parameters such as glucose and calcium, need to be used with caution. The results also demonstrated the extreme importance of urea and phosphorus for assessing stress response and mortality in tiger sharks, both parameters frequently neglected and of utmost importance for shark’s homeostasis.

Rufocumbre gen. nov. (type species: Rufocumbre celioi sp. nov.), a new genus of Neotropical skippers belonging to the tribe Moncini is described to include five species known only from Brazil. Four new species are described: Rufocumbre celioi sp. nov. from the states of Minas Gerais, Rio de Janeiro, São Paulo, Paraná, Santa Catarina and Rio Grande do Sul; Rufocumbre emeryi sp. nov. from the states of Mato Grosso, Distrito Federal, Goiás and Minas Gerais; Rufocumbre schneideri sp. nov. from the states of Tocantins, Distrito Federal, Minas Gerais and Paraná; and Rufocumbre lucasi sp. nov. from the states of Bahia and Minas Gerais. The taxon Cumbre belli eberti Evans, 1955 is transferred to the new genus and elevated to the species level, Rufocumbre eberti (comb. nov., stat. nov.). Adults, male androconia and genitalia of both sexes are illustrated for all species.

Translationally controlled tumour protein (TCTP) is an antiapoptotic protein highly conserved through phylogeny. Translationally controlled tumour protein overexpression was detected in several tumour types. Silencing TCTP was shown to induce tumour reversion. There is a reciprocal repression between TCTP and P53. Sertraline interacts with TCTP and decreases its cellular levels. We evaluate the role of TCTP in melanoma using sertraline and siRNA. Cell viability, migration, and clonogenicity were assessed in human and murine melanoma cells in vitro. Sertraline was evaluated in a murine melanoma model and was compared with dacarbazine, a major chemotherapeutic agent used in melanoma treatment. Inhibition of TCTP levels decreases melanoma cell viability, migration, clonogenicity, and in vivo tumour growth. Human melanoma cells treated with sertraline show diminished migration properties and capacity to form colonies. Sertraline was effective in inhibiting tumour growth in a murine melanoma model; its effect was stronger when compared with dacarbazine. Altogether, these results indicate that sertraline could be effective against melanoma and TCTP can be a target for melanoma therapy.

An alternative for reducing the degree of exploitation of natural oyster banks is to use artificial seed collectors. The effectiveness of said seed collectors, however, depends on the knowledge of the cycles and abundance of larvae in the plankton. This work aimed to study the presence of larvae of the genus Crassostrea in the Guaratuba Bay, which is located on the southern coast of Brazil, using two complementary methods: 1) visual identification followed by larval counts and 2) identification of the larvae at the species level using molecular biology. Measurements of abiotic parameters related to water quality (concentration and saturation of dissolved oxygen, pH, temperature, salinity and transparency) were performed every two weeks at three sampling points (Cabaraquara, Ilha da Sepultura and Parati) from January 2010 to April 2011 (n=32), and plankton was collected in 65 µm nets for larval research. Environmental parameters, particularly pH and the concentration of dissolved oxygen, influenced the presence of mollusc larvae in the Guaratuba Bay. The highest concentrations of larvae in the plankton occurred between September 2010 and January 2011, and the variation in larval abundance was observed mainly during the warmer seasons of the year (spring and summer).

Four new Brazilian species of Ruppeliana are described and illustrated: R. barbarensis sp. nov., R. grossii sp. nov., R. longiphallus sp. nov., and R. serrana sp. nov., the first from Minas Gerais State and the other three from Rio de Janeiro State. The new taxa can be easily distinguished from other Ruppeliana species by their color pattern and male genitalia morphology. Ruppeliana coronulifera (Stål, 1862) and R. taschenbergi (Berg, 1899) are synonymized with R. signiceps (Stål, 1862). Additionally, a diagnosis of the genus and a key to species are provided.
