A survey of selected coastal vegetation communities of Florida

摘要

A survey of coastal vegetation around Floridaudwas conducted during 1973 and 1974. Seventeen sites were selected and sampledudusing the transect method to determine species occurrence, relative densities, andudhabitat development and structure. Sites were sampled quarterly except where highudtides prevented data gathering. Species occurrence was compared within andudbetween sites using Sarensen's Index of Similarity (IS,) as a basis for determiningudsimilarity of species inhabiting selected sites. Indices ranged from 4 to 61%, theudformer representing only one plant common to two sites. Results showudenvironmental factors acting upon species alter species composition in seeminglyudsimilar habitats. Instead of the term "community", the term "association" is used toudbetter reflect the concept of a taxonomically unrelated group of plants occupying audparticular habitat. (Document has 40 pages.)
