Ecological biomechanics of marine macrophytes

open access: yesJournal of Experimental Botany, 2022
AbstractMacroalgae and seagrasses in coastal habitats are exposed to turbulent water currents and waves that deform them and can rip them off the substratum, but that also transport essential water-borne substances to them and disperse their propagules and wastes.

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

open access: yesRiver Research and Applications, EarlyView.
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.

Inter‐Annual Variation in Alpha and Beta Diversity of Benthic Macroinvertebrate Communities in Agricultural Ditches

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.

Lessons Learnt From Long‐Term Monitoring of River Restoration in an English Chalk Stream

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT River restoration can be difficult to evaluate due to insufficient monitoring over timescales too short to adequately capture physical and ecological response. To better understand restoration outcomes, this study quantified changes in physical habitat (depth, velocity, substrate composition) and macroinvertebrates at two restoration projects ...
