Beschreibung: Fisheries co-management is increasingly seen as a solution to the problems of resource use conflicts and overexploitation. The importance of transactions costs may not have been given adequate attention. The transaction costs are 1) information costs, 2) collective decisionmaking tools, and 3) collective operational costs. The various components of transaction costs of fisheries co-management systems are described in this paper. These costs need to be determined for evaluating the feasibility of a co-managed fishery compared to a centrally managed one.

Notizen: The Structure of the Alkaloid Juliprosopine from Prosopis juliflora A. Dc.A new alkaloid, juliprosopine, has been isolated from Prosopis juliflora A. Dc. (Leguminosae), for which structure 1 is proposed. The piperidine moiety could be elucidated on the basis of spectroscopic data (MS., 1H-NMR., 13C-NMR.) of juliprosopine and the derivatives 2-4. The central hexahydroindolizine part and its substitution pattern has been determined mainly on the bases of the Hofmann-degradation product 11, which yielded the hydrogenation products 13 and 14. By ozonolysis 11 was converted to 16 and 18. It is proposed that juliprosopine was built up in nature by two ‘monomeric’ Prosopis alkaloids and one dihydropyrrol unit.

Notizen: Structure X:R = H2 has been derived for the alkaloid kopsine from chemical and spectroscopic evidence and by a correlation with the alkaloid pleiocarpine (IX: R = R1 = COOCH3; R2 = H2). Structures XI: R = H2; R1 = OH; R2 = H and XI: R = H2; R1 = H; R2 = OH, respectively, represent dihydrokopsine-A and dihydrokopsine-B.
