Fauchald and Jumars's feeding guild classification is examined using 408 quantitative samples. Six major guilds are discussed; significant associations oc- curred between 'feeding guilds and depth, dissolved oxygen, and mean phi and gravel.' Coll. of Mar. Studies. Univ. of Delaware.

Annual production of the predominant chironomid (80%) was 'conservatively estimated' at ~5.8 g dry wt m-2yr -~ (one of the highest turnover ratios reported for the family). Larval biomass not removed by adult emergence was consumed by damselfly naiads, aquatic invertebrates and fish. EG&G, 151 Bear Hill Rd., Waltham, Mass. 02154. USA. (mwf)

Calculations of the energy content of [ood ingested by 3 developmental stages of S. elegans agree 'remarkably well with predictions based on respi- ratory requirements' (Feigenbaum, 1979). The oldest stage (mid-July) and the youngest stage (December) both experience energy deficits which correspond to heavy mortality periods in the population cycle (spawning and late hatching, respectively), Dept. of Oceanog., Dalhousie Univ., Halifax, N.S.

'No one doubts that organisms are well designed." The problem is to explain how the design has evolved from the particular circumstances. Within the constraints of arthropod (ostracode) design, many possible architectures exist: the fact that only a few of these appear and still fewer are repeated over and over indicates 'an adherence to structural relationships yet to be defined....The answers are in the fossil record. Are we asking the right questions?" Ostracodes, which periodically shed and reconstruct their exoskeletons. 'working by anticipation of success within very narrow limits,' are ideal study organisms for mechanical functional morphology, the topic of this review. Dept. of Paleobiol0gy. Natl. Museum of Nat.
