Floodplains provide a multitude of ecosystem functions and services with water purification being one of them. For this study we modelled the retention of total phosphorous (TP) in the floodplains of the river Rhine and the river Elbe, looking at sediment deposition as the main process responsible for removing TP from rivers during inundation events. We applied two different approaches: a proxy-based approach (PBA) and a one-d...

Aim I sotrema is a monophyletic subgenus of A ristolochia with species in E ast A sia and N orth/ C entral A merica. Earlier studies, based on limited sampling, suggested that the A sian and A merican species do not form two reciprocal sister clades. We reconstructed phylogenetic relationships within I sotrema to infer the biogeographical events that have shaped its present‐day distribution. Location E astern A sia, N orth A m...
