BENSON, K.R.: “The study of vertical zonation on ricky intertidal shores–A historical perspective Although zonation was noted within intertidal communities along the shorelines in Europe and the United States in the late nineteenth century, its causes were not investigated until the twentieth century. Beginning first at the University of Washington’s marine laboratory in the San […]

The heat-shock response and patterns of vertical zonation in intertidal Tegula congeners
TOMANEK, L.: The heat-shock response and patterns of vertical zonation in intertidal Tegula congeners What enables a marine invertebrate species to cope with the heat stress it experiences in the intertidal zone? Which biochemical and molecular assays are useful indicators for heat stress? Studies on marine gastropods of the genus Tegula, which occupy widely differing […]
The effect of variation in water temperature on the keystone predator Pisaster ochraceus
SANFORD, E.: The effect of variation in water temperature on the keystone predator Pisaster ochraceus Ecologists and physiologists have been drawn to the significant influences of aerial heat stress on intertidal organisms. Temporal variation in water temperature is an additional, often overlooked, factor that may have important effects on the physiology and ecology of intertidal […]
The effect of tide height, season, and water column productivity on the heat shock response in intertidal organisms
HALPIN, P. M. : The effect of tide height, season, and water column productivity on the heat shock response in intertidal organisms Intertidal organisms experience stress along a range of temporal and spatial scales. Ecologists and physiologists are currently being challenged to identify ecologically relevant physiological processes and their impact on biological communities. Here we […]
Predicting Disturbance to Mussel Beds Physiological Response to a Variable Wave Climate
CARRINGTON, E.: Predicting Disturbance to Mussel Beds: Physiological Response to a Variable Wave Climate Mussels often dominate the mid-intertidal zone of temperate rocky coasts, forming dense beds that exclude other primary space holders. The rate at which large storms remove mussels from their substrate strongly influences the intertidal community, and several recent advances have been […]
Physiological Tolerance Limits in Intertidal Crabs
STILLMAN, J.H.: Physiological Tolerance Limits in Intertidal Crabs Vertical zonation of intertidal organisms, from the shallow subtidal to the supralittoral zones, is a ubiquitous feature of temperate and tropical rocky shores. The results of many studies suggest that the upper range of a species’ vertical distribution is determined by tolerance limits to abiotic factors, while […]
Molecular chaperones in intertidal organisms Biochemical function and gene expression
HOFMANN, G.E.: Molecular chaperones in intertidal organisms: Biochemical function and gene expression The intertidal zone has historically been an important natural laboratory in which to test ideas about how physical factors such as temperature are transduced through organismal physiology to influence the distribution patterns of organisms. Key to our understanding of how the physical environment […]
Microclimate and biogeography The barnacle Chthamalus fragilis in New England
WETHEY, D. S.: Microclimate and biogeography: The barnacle Chthamalus fragilis in New England Geographic limits of species are commonly associated with climatic or physical boundaries, but the mechanisms of exclusion at the limits of distribution are poorly understood. In some intertidal populations, the strengths of interactions with natural enemies are mediated by microclimate, and determine […]
How do we measure the environment Linking ecology and physiology through biophysics
HELMUTH, Brian: How do we measure the environment? Linking ecology and physiology through biophysics Understanding the role of thermal stress in driving the ecology of intertidal animals and algae requires that we first quantify what the body temperatures of these organisms are under field conditions. While the temperature of an ectotherm’s body during high tide […]
Environmental Stress, Bottom-up Effects and Community Dynamics Molecular-Physiological Approaches Open New Vistas
MENGE, B. A.: Environmental Stress, Bottom-up Effects and Community Dynamics: Molecular-Physiological Approaches Open New Vistas Environmental stress and nutrient/productivity models predict the responses of community structure along gradients of physical factors and bottom-up effects. Although both models have succeeded in helping to understand variation in ecological communities, most tests have been qualitative. Until recently, two […]
