Abstract

SYNOPSIS. Continuous and discontinuous intertidal waters both experience fluctuations in salinity frequently accompanied by changes in temperature, levels of dissolved gases and pH. A multidimensional approach to environmental fitness may therefore be more representative of natural conditions in the intertidal zone. Various combinations of environmental factors are discussed including salinity/temperature, and salinity/O₂ tension. Salinity will directly affect osmotic and ionic regulation and indirectly affect acid-base balance and various components of the respiratory system including ventilation, gas exchange, perfusion, O₂ transport by the respiratory pigment and utilization at the tissues. Additional areas covered in this review article are osmotic problems faced by air-breathing aquatic intertidal animals, ontogenetic changes in osmoregulatory capabilities and a comparison of steady state (square wave) versus sinusoidal (cyclical) salinity changes.
