Tidal River Flood Risk Highest During Intermediate Rather Than Peak River Discharge
Abstract Tidal rivers are defined as the tide‐influenced, salinity‐free inland reaches of estuaries. Understanding the occurrence of peak water levels (PWLs) is critical for flood risk management, yet the timing and magnitude of PWLs in tidal rivers have been little studied. We address this gap by investigating PWLs during two catastrophic floods (1954

Functional divergence drives the prevalence of low‐abundance species in bat assemblages
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological communities are structured by a few common species, while most occur at low abundance. Understanding the drivers of this widespread pattern raises fundamental questions about community assembly rules and is important for applied ecology for identifying ...

The genetic population structure of riverine fishes is strongly shaped by the architecture of dendritic river networks, which can shift over both contemporary and geological timescales. Such river rearrangements are rarely incorporated into models of riverscape genetics, but they can have a profound effect on fish populations, especially when formerly ...
