This study evaluated the population structure, growth and longevity of Xiphopenaeus kroyeri in the State of Sergipe. The obtained data were compared with other populations on a latitudinal scale in order to evaluate whether the latitudinal paradigm applies to this species. Shrimp sampling took place monthly from September 2013 to August 2014, in nine stations distributed at 5, 15 and 30 m depths, using a shrimp fishery boat equipped with a ‘double rig’ net. Sexual maturity was estimated by the logistic function y = a/(1 + b*exp(-cx)), and the sex ratio was analysed with the Chi-square test. The individual growth rate was estimated using the von Bertalanffy model, and the longevity was estimated by the inverse form of this formula. A total of 6418 (3457 females and 2961 males) was analysed. The size at onset of sexual maturity was 12 mm of carapace length (CL) for males and 12.5 mm CL for females. The total sex ratio did not differ from the expected (1:1). Males exhibited higher growth coefficients (k) and smaller asymptotic growth (CC∞ = 28.74 mm, k = 0.0081 day−1) than females (CC∞ = 30.79 mm, k = 0.0058 day−1). The estimated longevity (years) was 1.55 for males and 2.15 for females. No evident latitudinal pattern was observed regarding the size at onset of sexual maturity or the growth parameters for X. kroyeri. The information found, besides contributing to the knowledge about the biology of this shrimp, can also clarify hypotheses presented in relation to the latitudinal paradigm along the Brazilian coast.

An updated synthesis of cyanobacteria and algae information is presented for Brazil aiming to refine the data gathered to date and evaluate the progress of the biodiversity knowledge about these organisms in the country since the publication of the Catálogo de Plantas e Fungos do Brasil. The results of 2015 showed an increase of 1,250 species (35.7%) when compared to 2010, reaching a total of 4,747 species. The most diverse classes in species number were the Bacillariophyceae, Conjugatophyceae, Florideophyceae, Cyanophyceae, Dinophyceae and Euglenophyceae. Bacillariophyceae and Cyanophyceae had the highest increase in species number in the five-year interval. The Southeast and South regions were the most diverse, however, the Northeast, with the states of Piauí and Sergipe, and the Central-west region, with Mato Grosso, Goiás and Distrito Federal, also stood out in the national algal biodiversity scenario. Despite the shortage of taxonomists and limited infrastructure, the results showed a significant improvement in the knowledge regarding the diversity of cyanobacteria and algae in the country during the study period, starting to even out regional geographical differences caused by subsampling. Key words: Biodiversity, phycology. ResumoApresenta-se uma síntese atualizada de informações sobre algas no Brasil objetivando refinar os dados reunidos até o presente, bem como avaliar os avanços sobre o conhecimento da diversidade de algas no país desde a publicação do Catálogo de Plantas e Fungos do Brasil. Os resultados de 2015 mostraram um acréscimo de 1.250 espécies (35.7%) a um total de 4.747 em relação a 2010. As classes mais diversas em número de espécies foram Bacillariophyceae, Conjugatophyceae, Florideophyceae, Cyanophyceae, Dinophyceae e Euglenophyceae. Bacillariophyceae e Cyanophyceae tiveram o maior acréscimo de espécies no intervalo de cinco anos. A região Sudeste e Sul foram as mais diversas, porém, as regiões Nordeste com os estados do Piauí e Sergipe e Centro-Oeste com os estados de Mato Grosso, Goiás e Distrito Federal destacaram--se no cenário da biodiversidade nacional. Apesar da escassez de taxonomistas e da infraestrutura limitada, os resultados obtidos evidenciaram um avanço significativo no conhecimento da diversidade de algas no país nesse período de cinco anos, iniciando uma mudança quanto as diferenças geográficas regionais. Palavras-chave: Biodiversidade, ficologia.

“…The continental shelf of Sergipe is considered one of the narrower shelves of Brazil (PEREIRA et al, 2014), shallow and with reduced width, ranging between 12 and 34.9 km with a gentle slope (1:1000) (LEMOS-JUNIOR et al 2014). The coastal zone of Sergipe presents a coastline of 163 km and is confined by the São Francisco river mouth, which separates the Alagoas State, in the north and the Piauí-Fundo-Real estuarine complex mouth, which separates the Bahia State, in the south (CARVALHO and FONTES, 2007).…”

RESUMOEste estudo avaliou se a reprodução e o recrutamento temporal e espacial das principais espécies de camarões marinhos explotados no Estado de Sergipe (Xiphopenaeus kroyeri, Farfantepenaeus subtilis e Litopenaeus schmitti) estão sendo protegidos, em comparação com normativa MMA nº 14, de 14 de outubro de 2004. As coletas foram realizadas de setembro/2013 a agosto/2014 na plataforma continental de Sergipe, em nove transectos, distribuídos nas profundidades de 5, 15 e 30m, utilizando um barco camaroeiro equipado com rede de arrasto de portas. Após as coletas os indivíduos foram identificados ao nível específico, subamostrados, sexados, mensurados quanto ao comprimento da carapaça e classificados quanto à morfologia gonadal. O recrutamento e a reprodução das três espécies ocorreram continuamente ao longo do ano, apresentando picos de intensidade. Indivíduos reprodutivos e juvenis foram mais abundantes nos 30m para F. subtilis, enquanto para X. kroyeri e L. schmitti foram mais abundantes nos 5m e 15m. A atual instrução normativa protege parcialmente as categorias reprodutivas e juvenis dessas espécies, principalmente F. subtilis. Portanto, sugere-se a adequação dos períodos de defeso para as épocas de reprodução e recrutamento de F. subtilis, uma vez que a área estipulada pelo IBAMA já protege as demais espécies ao longo do ano.Palavras chave: Xiphopenaeus; Farfantepenaeus; Litopenaeus; recrutamento; período reprodutivo; pesca. ABSTRACTThis study evaluated if the temporal and spatial reproduction and recruitment of the main species of marine shrimps exploited in the state of Sergipe (Xiphopenaeus kroyeri, Farfantepenaeus subtilis, and Litopenaeus schmitti) are being protected, in relation to the closed season based on the normative instruction MMA n° 14, of October 14 th 2004. The samples were collected monthly from September 2013 to August 2014 at the continental shelf of Sergipe, in nine transects, distributed in the depths of 5, 15, and 30 m using a shrimping boat equipped with double ring nets. After sampling, we identified shrimps to the species level; subsampled, sexed them, measured carapace length, and observed the gonads. Recruitment and reproduction in the three species occur continuously, albeit with intensity peaks. Regarding space, reproductive individuals and recruits were more abundant at 30 m in the case of F. subtilis, while for X. kroyeri and L. schmitti, higher abundances were found at 5 and 15 m. The current normative instruction partially protects the reproductive and juveniles categories of these species, mainly F. subtilis. Thus, we suggest closed seasons at breeding and recruitment seasons of F. subtilis, since the area set by IBAMA already protects other species throughout the year.
