Interactive effects between burrowing crayfish and flow conditions increase riverbank erosion: A flume experiment

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Biological and geomorphic effects have been treated independently in fluvial geomorphology. Flume experiments with burrowing crayfish show that interactions between these drivers do more geomorphic work than the sum of their maximum independent parts combined, meaning total biogeomorphic effects to rivers are likely underestimated.

Crustacean and Mollusc Shell Proteins: Origin, Structure, and Functionality

open access: yesJournal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Crustacean and molluscan processing as seafood generates a significant amount of shell waste annually, owing to the dense, mineral‐rich composition of the exoskeleton. Although valorization efforts have mostly focused on chitin and chitosan, the protein fraction remains underutilized despite its prominent nutritional, functional, and sensory ...

Colour Polymorphism in Coconut Crabs Is Under Relaxed Selection From Conspecifics?

open access: yesEthology, Volume 132, Issue 5, Page 359-364, May 2026.
Coconut crabs are either red or blue irrespective of age or sex, are nocturnal and have very few predators. This experimental study shows that they do not use conspecific's colour but do use relative size to settle competitive interactions over food in the wild.
