This work was carried outto evalutate the impact of cover crops species in the nutrient eyeling, soil quality, and passion fruit (Passiflora edulis; PF)-productivity. The treinaments consisted of four legumnous species: forage Arachis pintoi, Crotalaria spectabilis, Canavalia ensiformis, Cajanus cajan, cultivated in the interrow area, plus a control treatment (spontaneous species). In the first year, there was a significant effect to the cover crop on PF fruit production and on phosphorus (P), sulphur (S) and copper (Cu) concentration in leaves. The highest fruit production were observed in the A. pintoi and the control treatments. The highets concentration of P was found in PF plants cultivated with C. ensiformis Nevertheless, neither colonisation of plant roots by vesicular-arbuscular mycorrhizal (AM) fungi nor soil phospatase activity, nor soil P content could explain the differences in the P concentration. The cover crop and PF plants increased the number of AM spores in the soil .C.spectabilis negatively affected the S content in PF plants. The fruit production was significantly correlated with the content of S tissue, but not with teh soil sulfatase acitivity. In the control treatment, PF plants accumulated less Cu than with cover crops species. Biochemical parameters such as soil phosphatase and arylsulfatase activities were not significantly different among treatments, which is possibly related to soil fertility. In PF rows, the root-knot nematode Meloidogvne was founde to be mainly associated with the C.spectabilis treatment. However, no negative effects on PF fruit production were associated with the presence of this plant-paratise.

The present paper is a pioneering study on the Brachyura bycatch associated with the artisan prawn fisheries at the mouth of the Amazon River. The study was conducted at four collection sites distributed along the mouth of the Amazon River between the months of January/2009 and January/2010. The animals were caught using handcrafted traps called ?matapi?, which are used by prawn fisherman in the region. Twenty matapis were used at each collection site. A total of 145 specimens were captured and six species were identified, all belonging to the Trichodactylidae family - Sylviocarcinus maldonadoensis, S. pictus, S. devillei, Valdivia serrata, Dilocarcinus septemdentatus and D. pagei. The most representative species, S. maldonadoensis, S. pictus and S. devillei were classified as regular. Regarding the composition of the capture, there were three specimens of D. pagei , only one male specimen of D. septemdentatus, forty-eight specimens of S. maldonadoensis, sixty-eight specimens of S. pictus, twenty-two specimens of S. devillei and three specimens of V. serrata. In all months, the brachyuran fauna showed a considerably lower biomass when compared to the prawns, representing only 5% of the catch, in a ratio of 1:0.06. For most species, the number of males was always higher than the number of females in almost all collection months. |
