A numerical taxonomic approach (based on -100 characters) to brachyuran larvalclassificationhad to be abandoned due to the lack of sufficientdetail in existingdescriptions.The alternativeapproach, presented in enormous detail, utilizes more characters than usual, in particular the setation of the mouthparts, to arrive at a larval classification that corresponds well with family and sub-family adult taxonomy. Above the family level, variance sets in, suggesting a need for major revision of adult classification; however, a numerical approach would be highly desirable, since the present larval classification grew from the adult one and is necessarily somewhat circular. The vast degree of environmental adaptations exhibited by the B r a c h y u r a p r o b a b l y conceals phylogenetic relationships; as nearly all zoeae inhabit the same mid-water habitat, they should provide a better basis for phylogenetic taxonomy. Includes ca. 500 drawings, outlines of various classification schemes and ca. 300 references. Institute of Oceanographic Sciences, Wormley, Godalming, Surrey, U.K. (sir) 80:6044 Ritz, D. A., 1980. Tolerance of intertidal amphipods to fluctuating conditions of salinity, oxygen and copper. J. mar. biol. Ass. U.K., 60(2): 489-498. Abrupt changes in salinity with low levels coinciding with low O~ levels caused high mortality of Marinogarnmarus marinus (a marine species) but gradual changes caused no mortality. 'The brackish water species Gammarus duebeni suffered no mortality. Acute mortality to copper was greater in flowing than in static conditions.' G. duebeni could regulate O~ uptake over a wide range of O~ levels, but iV[. rnarinus could not. Zoology Department, University of Tasmania, Box 252C, G.P.O. Hobart 7001, Tasmania.

Maximum densities were reached in April-May, at times exceeding 100 m -3 Egg, juvenile and adult distributions are described and the life cycle discussed.

Availability of detritus of different types and ages to a polychaete macroconsumer, Capitella capitata. Limnol. Oceanogr., 25(3): 553-558. Homogeneous detritus prepared from periphyton, Gracilaria and Spartina, was aged for various periods of time and then introduced into microcosms so that microcosm carbon oxidation, microbial biomass (total adenylates) and net incorporation of the detritus by the worm, Capitella capitata, could be measured. The results indicated that the percentage of detritus partitioned into CapiteUa growth was lower for decay-resistant detritus, and that 'maximum microbial biomass coincided with maximum detrital oxidation.'

Numbers and stages of four copepod populations (Calanus propinquus. C. simillimus, Calanoides acutus, Rhincalanus gigas) at depths of 0-500 meters were investigated. All four were most abundant in the Antarctic Circumpolar Current and least abundant in the Weddell Sea.
