Physiological rates during development of marine invertebrates in temperate and polar oceans ...
The goal of this dissertation was to investigate the nutritional and physiological state of benthic marine invertebrates from both temperate and polar habitats. In Chapter 1, larvae of the temperate sea urchin Lytechinus pictus reared in the field were compared to those reared on cultured phytoplank...

The goal of this dissertation was to investigate the nutritional and physiological state of benthic marine invertebrates from both temperate and polar habitats. In Chapter 1, larvae of the temperate sea urchin Lytechinus pictus reared in the field were compared to those reared on cultured phytoplankton diets in the laboratory.

Protein synthesis rates for larvae reared in the field were ~50% less than larvae fed at near-maximal physiological capacities in the laboratory.
