THE FUTURE OF TRAIT-BASED APPROACHES IN RESEARCH AND MANAGEMENT
The combination of species functional traits provides insight into the environmental conditions to which species have adapted in space and time. These trait combinations are the result of evolutionary adaptations to the prevailing conditions of its habitat. Trait adaptations have phylogenetic constraints, similar to the constraints imposed by the body plan. Thus, species do not necessarily use all of their potential traits, traits will not have equal importance, and traits will always act in combinations. We hypothesise that two major filters decide on the occurrence of a species. First, speciation occurs along the evolutionary time scale. Here major environmental conditions, at the level of water type and within ecoregions, determined, together with phylogenetic constraints, the species’ distribution. Further speciation took place within water bodies, at the habitat scale. Habitat refers e.g., to oxygen, substrate and food. Using a Trichoptera database of >20,000 samples and a Trichoptera trait-database of 69 traits (471 categories) this hypothesis was tested for the Netherlands. Knowledge on the major filters provides the basis to predict future species occurrences and will support both restoration managers and scientists.
