Abstract

Summary: The functioning of present ecosystems reflects deep evolutionary history of locally cooccurring species if their functional traits show high phylogenetic signal (PS). However, we do not understand what drives local PS. We hypothesize that local PS is high in undisturbed and stressful habitats, either due to ongoing local assembly of species that maintained ancestral traits, or to past evolutionary maintenance of ancestral traits within habitat species‐pools, or to both.We quantified PS and diversity of 10 traits within 6704 local plant communities across 38 Dutch habitat types differing in disturbance or stress.Mean local PS varied 50‐fold among habitat types, often independently of phylogenetic or trait diversity. Mean local PS decreased with disturbance but showed no consistent relationship to stress. Mean local PS exceeded species‐pool PS, reflecting nonrandom subsampling from the pool. Disturbance or stress related more strongly to mean local than to species‐pool PS.Disturbed habitats harbour species with evolutionary divergent trait values, probably driven by ongoing, local assembly of species: environmental fluctuations might maintain different trait values within lineages through an evolutionary storage effect. If functional traits do not reflect phylogeny, ecosystem functioning might not be contingent on the presence of particular lineages, and lineages might establish evolutionarily novel interactions.

Abstract

Many studies focus on endophytic fungi. However, above-ground tissues of plants of the family Ericaceae are not largely examined. Most of the literature concerns the fungi forming ericoid mykorhiza. This bachelor thesis sums up the diversity studies of the endophytic fungi in the family Ericaceae, compares the frequency and the overlap of fungi in different host plants and geographical regions and also the occurence of fungi in living and dead plant tissues. The methods of fungal isolation and identification are accented.
