Abstract
The biomass distributions of marine benthic metazoans (meio- to macro-fauna,
1 μg–32 mg wet weight) across three contrasting sites
were investigated to test the hypothesis that allometry can consistently
explain observed trends in biomass spectra. Biomass (and abundance) size
spectra were determined from observations made at the Faroe–Shetland Channel
(FSC) in the Northeast Atlantic (water depth 1600 m), the Fladen
Ground (FG) in the North Sea (150 m), and the hypoxic Oman Margin
(OM) in the Arabian Sea (500 m). Observed biomass increased with body
size as a power law at FG (scaling exponent, b = 0.16) and FSC (b = 0.32),
but less convincingly at OM (b = 0.12 but not significantly different from
0). A simple model was constructed to represent the same 16 metazoan size
classes used for the observed spectra, all reliant on a common detrital food
pool, and allowing the three key processes of ingestion, respiration and
mortality to scale with body size. A micro-genetic algorithm was used to fit
the model to observations at the sites. The model accurately reproduces the
observed scaling without needing to include the effects of local influences
such as hypoxia. Our results suggest that the size-scaling of mortality and
ingestion are dominant factors determining the distribution of biomass across
the meio- to macrofaunal size range in contrasting marine sediment
communities. Both the observations and the model results are broadly in
agreement with the "metabolic theory of ecology" in predicting a quarter
power scaling of biomass across geometric body size classes.
