Taxonomic, functional and phylogenetic diversity: how subfossil cladocerans mirror contemporary community for ecosystem functioning: a comparative study in two oxbows
LIMNETICA 38(1) : 431-456. (2019)

Biases of taxa diversity and traits of source (active) and subfossil cladoceran communities with phylogenetic and functional approach were studied in two oxbows of the River Tisza, Hungary. Subfossil cladoceran communities were found to have suffered species loss due to both the degree of heterogeneity in the lake and taphonomical processes. The remains of heavily chitinized species are those most commonly found in the sediment, and therefore bias communities reconstructed on this basis. The subfossil cladoceran community in the Morotva-tó (MT) corresponded to low fish densities and the high macrophyte coverage, indicating weaker top-down forces in this oxbow. The phylogenetic and functional approach to subfossil cladocerans may be useful in paleolimnological reconstruction, since phylogenetic and trait-based diversity indices correctly predicted top-down regulation as a function of the ecosystem.
