Trait based and functional group approaches in algal ecology = Jelleg-alapú (trait-based) és funkcionális csoportosítások az algaökológiában

摘要

Trait-, guild- and functional group based methods became widespread in analysesudof spatial and temporal patterns of aquatic assemblages. The extended use of suchudgroupings can be explained by their joint feature: they decrease structuraludcomplexity of large data sets by decreasing the number of categories largelyudwithout loosing functional attributes. Thus, relating assemblages changes toudenvironmental drivers is greatly enhanced. This lecture will review the existingudtrait-, guild- and functional group based methods developed for phytoplanktonudand attached diatoms, their common and distinctive features along withuddemonstration of some case studies.
