13. Green turtles (Chelonia mydas) foraging at Arvoredo Island in Southern Brazil: genetic characterization and mixed stock analysis through mtDNA control region haplotypes
We analyzed mtDNA control region sequences of green turtles (Chelonia mydas) from Arvoredo Island, a foraging ground in southern Brazil, and identified eight haplotypes. Of these, CM-A8 (64%) and CM-A5 (22%) were dominant, the remainder presenting low frequencies (< 5%). Haplotype (h) and nucleotide ( π) diversities were 0.5570 ± 0.0697 and 0.0021 ± 0.001

19. Association of hypotalamic POMC, NPY and IRS2 with feeding behavior in norma and overweight Wistar rats / Associação do PMOC, NPY e IRS2 hipotalâmicos com padrões de comportamento alimentar em ratos wistar normais e sobrepeso
The feeding behavior of a specie is determined by a group of phylogenetic, ontogenetic, and epigenetic features, and regulated by internal and external factors to the organism. The natural phenomena that govern life in our planet are mainly periodic, and the food stocks is not an exception. Each harvest is followed by a time between harvests, and this rhythm

23. DinÃmica de nutrientes em solos arenosos adubados com esterco bovino por longos perÃodos / Dynamics of nutrients in sandy soils amended with cattle manure for long periods
Additions of farmyard manure (FYM) to the soil are a widely adopted alternative to supply nutrients, particularly nitrogen and phosphorus, in areas of subsistence agriculture in the semi-arid and agreste of Paraiba State. Additions of this residue in quantities that far exceed crop uptake, for long periods, can cause accumulation of nutrients in the soil. Th
