New gymnospermous woods from the Permian of the Parnaíba Basin, Northeastern Brazil, Part II: Damudoxylon, Kaokoxylon and Taeniopitys

This is the second contribution on the Permian permineralized flora of the Parnaíba Basin, NE Brazil that focuses on the gymnosperm woods from the Motuca Formation. We describe five new species of gymnospermous woods Damudoxylon buritiranaense sp. nov., Damudoxylon humile sp. nov., Damudoxylon roessleri sp. nov., Kaokoxylon punctatum sp. nov. and Taeniopitys tocantinensis sp. nov., and one new form, Taeniopitys sp. 1. The woods vary widely in their anatomy, mainly in their pith features, from simple parenchymatic to solenoid piths with canals and ducts, as well as different cells, such as secretory and sclerenchymatic ones. However, they have one characteristic in common - araucarian pitting in the radial walls of the tracheids. © 2013 Elsevier B.V.

Integrated quality assessment of sediments from harbour areas in Santos-São Vicente Estuarine System, Southern Brazil

Santos-São Vicente Estuarine System is a highly populated coastal zone in Brazil and where it is located the major port of Latin America. Historically, port activities, industrial and domestic effluents discharges have constituted the main sources of contaminants to estuarine system. This study aimed to assess the recent status of sediment quality from 5 zones of Port of Santos by applying a lines-of-evidence approach through integrating results of: (1) acute toxicity of whole sediment and chronic toxicity of liquid phases; (2) grain size, organic matter, organic carbon, nitrogen, phosphorus, trace metals, polycyclic aromatic hydrocarbons, linear alkylbenzenes and butyltins; (3) benthic community descriptors. Results revealed a gradient of increasing contamination for metals and organic compounds, alongside with their geochemical carriers. Sediment liquid phases were more toxic compared to whole sediment. Low number of species and individuals indicated the impoverishment of benthic community. The use of site-specific sediment quality guidelines was more appropriate to predict sediment toxicity. The integration of results through Sediment Quality Triad approach and principal component analysis allowed observing the effects of natural stressors and dredging on sediment quality and benthic distribution. Even with recent governmental efforts to control, pollution is still relevant in Port of Santos and a threat to local ecosystems. © 2013 Elsevier Ltd.

Biologia populacional e reprodutiva do camarão sete-barbas na Baía de Santos, São Paulo

We investigated the sexual maturity, reproductive period and juvenile recruitment (both associated with salinity and temperature of bottom water) and sex-ratio of Xiphopenaeus kroyeri in Santos Bay, São Paulo. Monthly samples were obtained from June 2008 through May 2009 along four transects. Individuals were measured, sexed and the developmental stage of the reproductive system was macroscopically determined. The mean carapace length of females was larger than that of males. Females attained physiological maturity with 25.5 mm and males with 16.8 mm. The reproductive period was continuous with higher proportions of reproductive females in autumn. Although not significant, in February occurs a peak of reproductive females similar to March. An intermediate peak of these females occurs between August and October and it contributed to the recruitment in summer. The smallest amount of juveniles after the main peak of spawning (February, March and April) can be explained by migration or consequences of open access for fishery that occurs on June. The overall sex-ratio was approximately 1:1. However, when considering the spatial distribution, we observed a greater amount of reproductive females in shallow waters in the bay. The differential distribution between the sexes could be associated with appropriated areas to spawn. The current legal off-season occurs between March and May, and, according to our results of the frequency of reproductive females, we suggest the inclusion of February in the off-season.
