Plankton community respiration: relationships with size distribution and lake trophy

摘要: Allometric interpretations of community size structure often assume that laboratory relations between physiological rates and body apply in the field, but this assumption is rarely examined critically. We therefore tested hypothesis limnoplankton respiration are predictable functions mean size, compared these to relations. Over a broad range trophic conditions (6.5 ≤ [TP] 130 μg I−1; 1.2≤ [chl-a] 29 1−1 ), rate per organism for picoplankton, nannoplankton, net plankton assemblages was power function with an exponent 0.73. When (R) biovolume (B) standardized equivalent carbon units, R/B ratio −0.30. These results provide empirical support contention distributions may be used construct comprehensive models physiology. The total epilimnetic phosphorus concentration correlated both community, as well three classes; so aspects also lake state.
