Botanical inventory of the early book herbaria of Leonhard Rauwolf from southern France and northern Italy (1560–1563)

TAXON, Volume 75, Issue 4, August 2026.
Abstract Sixteenth‐century herbaria are the oldest plant collections that survive today and, as such, they provide valuable insights in past floras and historical botanical interactions. One of the most fascinating still extant 16th‐century herbaria is the four‐volume collection of the German physician, botanist and traveler Leonhard Rauwolf (1535 ...

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

Geophysical 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

River 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.

Aquatic and Littoral Successions in Various Post‐Mining Sites—Patterns and Possible Use in Ecological Restoration

Land Degradation &Development, Volume 37, Issue 9, Page 3842-3852, 30 May 2026.
ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...
