Isoanemeity Predicts the Effect of Leaf Versus Stem Flexure on Plant Drag

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Flexible vegetation is deflected by fluid flow, reducing drag forces and thus inducing complex feedbacks which affect scalar transport, sediment mobility and biogeochemical cycling. However, we presently lack mathematical models for this disturbance, for all but the simplest plant forms.

Comparison of Conventional, Rake, and Sonar‐Based Biophysical Habitat Measurements in a Shallow Ontario River

open access: yesRiver Research and Applications, Volume 42, Issue 5, Page 1011-1021, June 2026.
ABSTRACT Knowledge of habitat availability is critically important for the management and recovery of freshwater species. Quantifying habitat availability often requires fine‐scale sampling at point‐based locations across a large geographic extent, which can be laboursome.
