A field investigation of diffusion within a submerged plant canopy
Saltwater marshes and wetlands are important buffers at the land-sea interface. Among the most biologically active ecosystems on Earth, natural and man-made wetlands are important interceptors of pollutants and nutrients bound for the coastal ocean. The transport, dilution, and deposition processes …

Ecology of chemical defenses of algae against the herbivorous snail, Littorina littorea, in the New England rocky intertidal community
In the New England rocky intertidal community, space is dominated by two perennial plant types, brown fucoid algae (Ascophyllum nodosum and several species of Fucus) in the mid zones and the red alga Chondrus crispus in the low zones. These algae are not grazed by the predominant herbivorous snail, …

Vertical zonation of three species of California limpets (Acmaeidae) as a function of predation
<p>Various studies indicate the acmaeid limpet species Collisella digitalis, Collisella pelta and Notoacmea scutum inhabit different vertical zones in the rocky-intertidal region. At Sunset Bay, Oregon, Shotwell (1950) found that C. digitalis was situated in the upper intertidal C. pelta inhabited …

The structure of experimental clastic-substrate marine communities
<p>It is hypothesized that difference between containers and between sediments will produce structural differences in the resulting communities by intensifying competition for resources, and by excluding certain classes of predators. It is also hypothesized that the level of the effect of …
