Influences of a submerged macrophyte on colony formation and growth of a green alga
The effects of the submerged macrophyte Ceratophyllum demersum on the growth and morphology of the green alga Scenedesmus obliquus were assessed by conducting co-culture laboratory experiments (15 and 25°C, presence/absence of 3 g fresh wt of C. demersum

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
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.
