Summary: Located in Southeast Brazil, the Paraiba do Sul River Basin is crucial as a freshwater source for over 14.3 million people. Concerns arise due to population growth and increased demand for water, as well as the combined impact of land use changes and climate change on water availability. This study uses a crop simulation model to analyze the water requirements of paddy rice under different climate scenarios and land use projections, estimating water footprints and exploring sustainable production practices. It is found that implementing rational soil fertility and water management can significantly boost productivity and reduce water use, compensating for the expected decrease in rice production caused by urban sprawl.

Summary: The middle Paraiba do Sul River region, home to Brazil's largest steel industry, has experienced accelerated sedimentation in reservoirs due to industrial activities. This study aimed to determine the sediment accumulation rate using Pb-210 dating. The results showed a significant increase in sediment accumulation rate over the years. Chromium and zinc concentrations decreased, indicating improvements in environmental policies. Mercury concentrations were attributed to changes in sediment granulometry caused by land use transformations.

Summary: The intraspecific variation of the gross morphology of the retractor muscle was studied in Parathyone braziliensis and Thyonidium seguroensis. Contrary to early expectations, anatomical evidence did not support the idea that the point of origin of the retractor muscle and the split of the muscle bands could be used as age-related or taxonomic characters to differentiate species.

Summary: The taxonomic status and distribution of some species of the genus Emerita in the western Atlantic were uncertain. A thorough examination of morphological differences and genetic markers revealed a new species, Emerita almeidai, along the Brazilian coast. Molecular phylogenetic analysis showed that individuals previously identified as E. portoricensis were actually divided into two clades, one from the Brazilian coast and the other from Central America. This study increases the number of species in the genus Emerita to 12, with different distributions in the Atlantic, Indo-Pacific, and eastern Pacific.

Summary: We compared the fecundity and reproductive effort of two hermit crab species, Clibanarius antillensis and Calcinus tibicen, distributed along the Brazilian coast. Samples were collected at two locations separated by approximately 3000 km - Pedra Rachada Beach (Ceara) in the NE region and Araca Beach/Grande Beach (Sao Paulo) in the SE region. The results showed higher values for females of both species collected in the SE localities, with the presence of aberrant eggs affecting the reproductive parameters in NE females and resulting in lower reproductive effort. The variation in reproductive performance may be related to the latitudinal location and habitat characteristics.
