Which trait dissimilarity for functional diversity: trait means or trait overlap?

Popis výsledku v původním jazyce

Question: Many functional diversity indices require the calculation of functional trait dissimilarities between species. However, very little is known about how the dissimilarity measure used might affect conclusions about ecological processes drawn fromfunctional diversity. Methods: We simulated real applications of functional diversity, to illustrate the key properties of the two most common families of dissimilarity measures: (1) Gower' distance, using only mean trait' value per species and then standardizing each trait, e.g. relative to its range; (2) trait overlap' between species, which takes into account within-species trait variability. We then examine how these approaches could affect conclusions about ecological processes commonly assessed with functional diversity. We also propose a new R function (trova', i.e. TRait OVerlAp) which performs computations to estimate species trait dissimilarity with different types of data. Results: The trait overlap approach generally produc
