Water fog composition was investigated at a fog harvesting installation in the coast of Atacama (North Chile). Chañaral is historically affected by mining contamination discharges. Hydro-chemical characterization of fog water from top of the mountain (where capture installation is located) and at the bottom of the mountain (after vertical transportation where an aquaponic system is located) revealed many compositional differences that compromise the use of water. High acidity and high concentrations in Cu and As in water collected on top of the mountain were found; meanwhile, acidity and Cu decreased, and As levels overpassed the drinking water standards after the vertical transportation. Collected data was assessed according to national and international regulatory standards, neutralization factors (NF), sodium adsorption ratio (SAR), and ion ratios to determine origin of contamination and suitability of destined for human consumption, irrigation, or aquaculture purposes.

The development of host fish techniques (in vivo) at the beginning of the 20th century, and the improvement of artificial culture media for in vitro culture of bivalves, provided an opportunity to identify the nutritional requirements needed to complete the life cycle of threatened freshwater bivalves. A freeze-dried extract of lambari, a Brazilian Tetra (Astyanax altiparanae), was used as an additive to the artificial culture medium M199 (Sigma®) to try to improve the survival of glochidia and the metamorphosis of Diplodon rotundus gratus and D. greeffeanus. We adjusted the pH of the culture medium to 6.8, the same value recorded at the collecting site of the bivalves. Glochidia were kept in an incubator at 18ºC. 40% of D. rotundus gratus glochidia survived, and 20% reached metamorphosis after 22 days of incubation. For D. greeffeanus 50% of the glochidia survived with 15% undergoing metamorphosis after 22 days of incubation. These results suggest an increase in the post-metamorphic survival with the use of the medium M199 supplemented with the fish extract, with a survival percentage of 75% after 30 days at the juvenile stage. Therefore, this constitutes an effective process in the preparation of in vitro cultures for freshwater mussels, particularly for D. rotundus gratus and D. greeffeanus.

O humanista português Antônio de Gouveia publicou dois livros de epigramas em latim, nos anos de 1539 e 1540, em Lyon, renomado centro da Renascença francesa. A partir de um conjunto de quatro desses poemas, imitados de Marcial, podemos constatar a importância da herança clássica na literatura daquele período e os procedimentos poéticos intertextuais que nortearam a composição dessa obra exemplar.
