Physiological Ecology of Rocky Intertidal Organisms: A Synergy of Concepts1
نویسندگان
چکیده
SYNOPSIS. The rocky intertidal zone is among the most physically harsh environments on earth. Marine invertebrates and algae living in this habitat are alternatively pounded by waves and exposed to thermal extremes during low tide periods (Denny and Wethey, 2001). Additionally, they must deal with strong selective pressures related to predation and competition for space (Connell, 1961). As a result, the steep physical gradient and spatially condensed community has made the rocky intertidal zone an ideal ‘‘natural laboratory’’ to study the coupled role of physical and biological factors in determining the abundance and distribution of organisms in nature (Connell, 1961; Paine, 1966, 1994).

متن کاملThe Antagonistic Effect of Raised Salinity on the Aerobic Performance of a Rocky Intertidal Gastropod Nassarius deshayesianus (Issel, 1866) Exposed to Raised Water Temperature
Rocky intertidal organisms are facing pronounced fluctuations in environmental conditions even at small spatial and temporal scales. This heterogeneous habitat is a proper model system to investigate effects of physical parameters and their interactions on physiological performances of marine organisms. In the intertidal zone (especially in tidal pools), the temperature and salinity usually inc...
متن کاملThe study of seaweeds biomass from intertidal rocky shores of Qeshm Island, Persian Gulf
Rocky shores are one of the most important habitats of marine environment in coastal areas. They host marine organisms including seaweeds because of existence of strong and stable substrate for their growths. Intertidal rocky shores are a prominent feature on coastal areas of Qeshm Island located at the northern part of Strait of Hormuz. In order to study biomass of seaweeds on rocky intertidal...
متن کاملThe Ecomechanics of Mussel Attachment: From Molecules to Ecosystems1
SYNOPSIS. One aspect of the physiological ecology of intertidal organisms is their mechanical design, which can be explored at many hierarchical levels, from molecules to ecosystems. Mechanical structures, as with any other physiological feature, require energy to construct and maintain, are subject to manufacturing and evolutionary constraints, and influence ecological performance. This contri...
