| ABSTRACT The objective of this study was to analyze technically and economically the irrigated ‘Gália’ melon (Hybrid Nectar), cultivated in greenhouse with and without using plastic mulch covering on the soil. Simultaneously, two experiments were conducted using a completely randomized design (CRD), in which melon plants were submitted to five water availability levels, defined by 50, 75, 100, 125, and 150% of crop evapotranspiration, with four replicates. The difference between experiments were only about the soil covering with plastic mulch: with (CC) or without (SC) plastic mulch. The economically optimal irrigation depths were 208.83 and 186.88 mm, resulting in yields of 50.85 and 44.51 t ha-1 for the experiments with and without mulching,... |

| Aiming to evaluate the development of seedlings of Schinus terebinthifolius under different irrigation depth, an experiment was installed in a greenhouse. The experimental design used was randomized block consisting of 4 treatments with 3 blocks. The irrigation depths evaluated were 8, 10, 12 and 14 mm daily, respectively T1, T2, T3 and T4. Seedling production was performed in tubes with 280 cm ³ filled with pine bark basis substrate and fertilizer. The development of the seedlings, were evaluated by the following characteristics: height of aerial part (APA), diameter at breast height (D),dried mass weight of roots (PMSR), dried mass weight of aerial part (PMSPA), total dried mass (MST) and relation (h/d). The treatment T3 presented the best results in... |

| We analyzed the influence of time, tide and water depth on the activity and spatial distribution of estuarine dolphins Sotalia guianensis in Pontal Bay, Ilhéus, Brazil. Direct observations were carried out at four fixed points from January to December of 2006. Estuarine dolphins were sighted in 11 out of 12 months and in 30% of 181 sampling periods. The average group size, which was 3.75 ± 1.59 (n = 64), did not vary significantly by month (Kruskal-Wallis, H = 10.6729; p = 0.3836). Infants and adults represented 18 and 82% of the individuals whose age we were able to determine, respectively. Estuarine dolphins were more frequently present than expected in areas deeper than 3 m (regression GLM, z = 3.773; p = 0.0002). The animals were more frequently... |
