Abstract:We have studied the long- and short-term periods of seabird influence on
coastal vegetation. In the Aleutian Islands during the Holocene,
terrestrial predators were virtually absent; as a result, large seabird
colonies thrived along the coasts or across entire islands. Bird guano
enriches the soil with nitrogen, which can lead to the formation of
highly modified ornithogenic (bird-formed) ecosystems. The vegetation of
several Aleutian Islands has been reconstructed; however, only the
vegetation on Carlisle Isl… Show more
