| The shape invariance of the marine PSD | Prev topic | Next topic |
PSDs in natural waters are remarkably similar to each other (for example, Cavender-Bares et al 2001, Jonasz and Zalewski 1978) as far as their shapes are concerned. Sabetta et al (2005) have recently examined body size-abundance distributions (i.e. PSDs) of nano-plankton (2 to 20 µm) and micro-phytoplankton (20 to 200 µm) (see Plankton) in the coastal Mediterranean Sea. Their study suggests that the relative shape-invariance of the PSD of phytoplankton is caused by an essentially continuous substitution of one species for another when environmental conditions change.
