Scotland.</I><B><P> Abstract: </B>Over the period 1969 to 1980, 34 stations (both inter and subtidal) were visited in Loch Ewe, a fjordic sea loch on the west coast of Scotland. Amphipod densities were determined along with sediment particle size and levels of organic carbon and chlorophyll <I>a</I>. Multivariate analysis of these data indicates that depth and sediment organic carbon levels are the major determinants of amphipod assemblages in the loch, in contrast to previous studies which have variously implicated temperature, sediment granulometry and food availability.<I><B><P> Resume: </B></I>Au cours, de la periode 1969-1980, on a visite 34 stations (intertidales ou subtidales) dans le loch Ewe, bras de mer comparable aux fjords situes sur la cote occidentale de I'Ecosse. Les densites d'amphipodes ont ete determinees, ainsi que, comme parametres sedimentaires, la taille des particules et les teneurs en carbone organique et en chlorophylle <I>a</I>. Le traitement de ces donnees a l'aide de l'analyse factorielle multivariee indique que la profondeur et le contentu en carbonne organique des sediments constituent les determinants majeurs des assemblages d'Amphipodes se produisant dans le loch Ewe, ce qui<B> </B>est en desaccord avec les resultats d'etudes anterieures qui ont implique de diverses manieres la temperature, la granulometrie sedimentaire et la disponibilite d'aliments.<P> Cah.
