Environmental factors influencing the distribution of three species within the genus Persephona Leach, 1817 (Crustacea, Decapoda, Leucosiidae) in two regions on the northern coast of Sao Paulo State, Brazil

Patterns of spatio-temporal distribution of Brachyura are determined by the interaction among life history traits, inter and intraspecific relationships, as well as by the variation of abiotic factors. This study aimed to characterize patterns of spatio-temporal distribution of Persephona lichtensteinii, Persephona mediterranea and Persephona punctata in two regions of the northern coast of Sao Paulo State, southeastern region of Brazil. Collections were done monthly from July 2001 to June 2003 in Caraguatatuba and Ubatuba, using a shrimp fishery boat equipped with double-rig nets. The patterns of species distribution were tested by means of redundancy analysis (RDA) and generalized linear mixed models (GLMM) in relation to the recorded environmental factors (BT: bottom temperature, BS: bottom salinity, OM: organic matter and granulometry (Phi)). The most influent environmental factor over the species distribution was the Phi, and the ascendant order of influence was P. lichtensteinii, P. punctata and P. mediterranea. The greater abundance of P. mediterranea showed a conservative pattern of distribution for the genus in the sampled region. The greater occurrence of P. punctata and P. lichtensteinii, in distinct transects than those occupied by P. mediterranea, seems to be a strategy to avoid competition among congeneric species, which is related to the substratum specificity.

Urbanização, turismo e seus impactos nos recursos naturais no município de Ilhabela - SP

The urbanization process in the Brazilian cities is directly linked to its main economic activities, and causes several impacts on the natural resources. It can be seen at the city of Ilhabela, an archipelago located at the north coast of the state of São Paulo, that still has a great area of preserved Atlantic Rainforest, and where today the tourism is the main economic activity. With this in sight, this paper aimed to make a prospect of the current situation of the city, looking at the main aspects of its economic and urban development and the environmental impacts related to them. Among the aspects studied, are the irregular occupations at preservation areas on the island: the pressure on the sea ecosystems by the fishing and the boat circulation, and at the beaches by the tourists flow. Were also observed the characteristics of the city’s urban infrastructure, such as the water supply, sewer and road networks and the waste collecting. Finally, it was analyzed the way that the government acts over the preservation of the island’s natural resources, by the Municipality and the Ilhabela State Park, so that the acting of these two agents could be compared

Projeto Porto para todos: Proposta de modernização e revitalização da paisagem da área portuária de Santos-SP

O Porto de Santos, o maior e mais importante porto da América Latina, é afetado por diversos problemas que também afligem muitos portos no Brasil e no mundo, como o trânsito complicado, estacionamentos mal planejados, áreas abandonadas, deterioração das áreas urbanas próximas ao porto, além da falta de interação entre porto e a cidade, resultando em um espaço totalmente dissociado de sua vizinhança. Trabalhando o conceito do turismo na região, este trabalho propõe a revitalização e a requalificação de áreas deterioradas e ociosas da zona portuária, cuja área de atuação se concentra na faixa entre o Terminal Marítimos de Passageiros do Porto de Santos (Concais) e a área próxima ao Ferry Boat, onde ocorre a Travessia de Balsas Santos-Guarujá, propondo uma experiência única tanto para os cidadãos santistas, como para o turista que desembarca no Concais e pretende conhecer outras partes da cidade ou mesmo as praias do Guarujá. Com isso propõe a implantação de áreas ajardinadas e praças, e equipamentos de lazer e turismo entre outros, beneficiando a população, otimizando a atividade portuária e gerando mais ônus para a cidade, além de finalmente integrar eficientemente a área portuária à urbana, destacando cada vez mais os pontos fortes e característicos da cidade

Lifespan and reproductive dynamics of the commercially important sea bob shrimp Xiphopenaeus kroyeri (Penaeoidea): synthesis of a 5-year study

Population parameters of the shrimp Xiphopenaeus kroyeri (Heller, 1862) (sex ratio, length-frequency distributions (carapace length, CL), growth, lifespan, size of sexual maturity, spawning and recruitment) were analyzed in a long-term study from January 1998 through June 2003. The data on these parameters were collected and analyzed to test the hypothesis that the main period of juvenile recruitment in the bay coincides with the period of fishery closures currently designated by the Brazilian Institute of Environment and Renewable Natural Resources. Monthly collections were conducted along the southeastern Brazilian coast, using a shrimp fishing boat with “double-rig” nets sampling at stations up to 40 m depth. Sex ratios were female-biased only in zones with high reproductive activity such as in stations deeper than 15 m (χ2 test, p<0.05). The mean size of males and females was 15.3 ± 3.1 mm CL and 16.2 ± 4.7 mm CL, respectively, with size at sexual maturity estimates (CL50) of 14.8 mm for males and 15.5 mm for females. Mean growth curves provided estimates of CL∞ = 29.31 mm, k = 0.009/day, t0=−0.25 and CL∞ = 35.33 mm, k = 0.006/day, t0=−0.23 for males and females, respectively, and average lifespans of 1.35 for males and 2.12 years for females. Recruitment and abundances of reproductive females were highly correlated with the environmental factors such as higher water temperature and finer-grained bottom sediment (canonical correlation, r=0.63, p<0.001). The reproductive peaks in February-April 1998, March-May 1999 and February-May 2002 were followed by recruitment peaks in May-July 1998, July-September 1999 and April-June 2002, respectively. Thus, the proposed period of fisheries closure (March to May) does not coincide with the main recruitment periods observed for X. kroyeri.

Assessment of reproductive capacity in females of Smith, 1869 (Brachyura, Portunoidea) during a period of high reproductive activity

The reproductive capacity of the swimming crab Callinectes danae Smith, 1869 was assessed based on the reproductive investment (RI) of ovigerous females and the gonadosomatic index (GI) of non-ovigerous adult females. Crabs were collected in June 2009 with a shrimp fishing boat at Ubatuba (23° 26′S 45° 02′W) São Paulo, Brazil. Overall, 191 adult females were analyzed, of which 108 were ovigerous and 83 non-ovigerous. The size of ovigerous females ranged from 54.5 to 79.8 mm carapace width (CW) and non-ovigerous females ranged from 56.0 to 80.9 mm CW. RI values did not differ among the size classes (ANOVA, p > 0.05), with an overall mean of 15.8%. The same occurred with the Gonadossomatic index for non-ovigerous females, for which the mean value was 11.7%. The regression between the dry weight of the egg mass and the dry weight of the crab (Student’s t, p = 0.25; ttab = 1.66; tcal = 0.66) indicated an isometric relationship for the variables analyzed. The simultaneous occurrence of gonadal maturation and embryonic development in ovigerous females suggests that these crabs may spawn at least twice in the same breeding season and reveals the need for evaluation of the allocation of energy in subsequent spawns.
