(3Z,6Z,8E)-3,6,8-dodecatrien-1-ol : Sex pheromone in a higher fungus-growing termite, Pseudacanthotermes spiniger (Isoptera, Macrotermitinae) Inra
Bordereau, C.; Robert, A.; Bonnard, O.; Le Quere, J.L..
The female sex pheromone of the fungus-growing termitePseudacanthotermes spiniger (Termitidae, Macrotermitinae) was isolated from sternal glands of alates. The compound inducing attraction and excitation in males was identified as the (3Z,6Z,8E)-3,6,8-dodecatrien-1-ol by GC-MS, microhydrogenation, GC-FTIR, and NMR. This unsaturated alcohol is present in both sexes but in much higher quantities in females than in males (about 10 times). The hypothesis is suggested that this alcohol, which is detected at extremely low concentrations by the workers ofP. spiniger, may be used either as a trail-following pheromone or a sex pheromone according to concentrations and to target castes. The presence of this alcohol in Macrotermitinae reinforces the idea of a...

A 4-years' analysis of the meiofauna community of a dumping site for TiO<sub>2</sub>-waste off the Dutch coast OMA
Smol, N.; Huys, R.; Vincx, M..
Sublittoral meiofauna of 24 stations was monitored over 4 years (1984-1987) in and around a dumping site for TiO<sup>2-</sup> acid waste in the Southern Bight of the North Sea off the Dutch coast. The meiofauna was examined quantitatively and qualitatively with special reference to the nematode and the copepod community structure down to species level and to the trophic structure of the nematodes. Biological, sedimentological, geographical parameters and the concentration of several heavy metals were subject to multivariate statistical analysis and classification techniques to evaluate the impact of the TiO<sup>2-</sup> dumping activities. The meiofauna is dominated by nematodes, copepods, gastrotrichs and turbellarians. There is a...

A BIOECONOMIC ANALYSIS OF THE NORTHERN ANCHOVY AgEcon
Conrad, Jon M..
A simple bioeconomic model was specified and estimated for the central subpopulation of the northern anchovy (Engraulis mordax). Net population growth was described by a power function and harvest by the U. S. reduction fleet was modelled by an exponential production function. When incorporated into a bioeconomic model they allowed the derivation of two explicit functions, Y = Ö(X) and Y = Ø(X) which could be used to depict the bioeconomic optimum. The roots of Ö(X) have important economic interpretations and can be used to characterize the economic status of the fishery. The positively-sloped segment of the Ö(X) curve may be used as an approximately-optimal adaptive management policy. For the set of bioeconomic parameters circa 1990, anchovy biomass...
