Résumé : |
Vegetation studies in species rich neotropical forests are greatly hampered by high species numbers, identification difficulties, and large sample areas necessary to adequately cover species rich woody plant communities as well as by logistic, financial, personal, and temporal limitations. In the present study, we assessed the representativeness and usefulness of 65 plants families as indicator groups for such studies. Generally speaking, we found that the species associations in any family provided substantially more information about the relationship between vegetation plots than would be indicated by the percentage value of species number of the respective family. Thus, the loss of information from not considering the whole flora was more than outweighted by the possibility to incr[...]
Vegetation studies in species rich neotropical forests are greatly hampered by high species numbers, identification difficulties, and large sample areas necessary to adequately cover species rich woody plant communities as well as by logistic, financial, personal, and temporal limitations. In the present study, we assessed the representativeness and usefulness of 65 plants families as indicator groups for such studies. Generally speaking, we found that the species associations in any family provided substantially more information about the relationship between vegetation plots than would be indicated by the percentage value of species number of the respective family. Thus, the loss of information from not considering the whole flora was more than outweighted by the possibility to increase sample sizes, and by easier and more complete identification. This effect varied greatly between plant families (mainly in relation to biogeographic differences) as well as |
