Comparative ichthyotoxicity of shallow and deep water sponges of New Caledonia;International coral reef symposium : poster

We have conducted a survey of toxicity distribution with depth of common marine sponges of the Southern province of New Caledonia. Test fish #Gambusia affinis$ (#Vertebrata, Pisces$) were exposed to aqueous macerates from 30 shallow water and 30 deep...

Structure and temporal fluctuations of two interdital seagrass-bed communities in New Caledonia (SW Pacific ocean)

The structure and trophic organisation of two intertidal seagrass-bed communities (#Halodule uninervis$ and #Thalassia hemprichii$ were examined on the South-West coast of New Caledonia (SW Pacific Ocean), from April 1989 to March 1990. Five benthic ...
