Aleuts, sea otters, and alternate stable state communities Aleuts, sea otters, and alternate stable state communities

Reexamination of stratified faunal components of a prehistoric Aleut midden excavated on Amchitka Island, Alaska, indicates that Aleut prey items changed dramatically during 2500 years of aboriginal occupation. Recent ecological studies in the Aleutian Islands have shown the concurrent existence of two alternate stable nearshore communities, one dominated by macroalgae, the other by...

Sea otter predation and community organization in the western Aleutian Island, Alaska Sea otter predation and community organization in the western Aleutian Island, Alaska

Predation by the sea otter (Enhydra lutris) limits epibenthic invertebrates, especially sea urchins (Strongylocentrotus polyacanthus), in turn allowing a luxuriant development of the macroalgal canopy. Where sea otters are abundant, sea urchins are small and scarce in shallow water, and the association of fleshy macroalgae apparently is regulated by competition. Sea urchins are larger...

Reproduction of chaparral shrubs after fire: A comparison of sprouting and seeding strategies Reproduction of chaparral shrubs after fire: A comparison of sprouting and seeding strategies

The relative ability of sprouting and nonsprouting chaparral shrubs to recover from fire was studied by examining population of congeneric pairs of species in burned and adjacent unburned areas. The pairs of species selected, with the nonsprouting species named first, were Arctostaphylos glauca - A. glandulosa and Ceanothus greggii - C. leucodermis. Data were also obtained on certain...
