Diffusive Behavior and Statistical Evolution of Sediment Transport From DNS‐DEM and Stochastic Models

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Sediment transport in rivers and channels can be understood as a diffusive phenomenon, where sediment particles separate as they move downstream. This diffusive behavior can be Fickian or anomalous (superdiffusive, subdiffusive, ballistic, etc.), depending on the time evolution of the sediment displacement variance.

Small collections, great findings: three new species and two new state records for Asteraceae from Brazil

Nordic Journal of Botany, Volume 2025, Issue 12, December 2025.
The BHZB herbarium was founded in 1993 with about 16 787 registers – a number that has to be considered as small when compared to larger herbaria in Brazil. In the BHZB, 97.5% of the vouchers are from the Minas Gerais state (ca 16 372 specimens), with Asteraceae being the best represented family.
