Spatially structured genetic variation in a broadcast spawning bivalve: quantitative vs. molecular traits [PDF]
Understanding the origin, maintenance and significance of phenotypic variation is one of the central issues in evolutionary biology. An ongoing discussion focuses on the relative roles of isolation and selection as being at the heart of genetically based

Epibiosis and masking material in the spider crab Maja squinado (Decapoda: Majidae) in the Ría de Arousa (Galicia, NW Spain) [PDF]
[Abstract] Majid crabs present a marked masking behaviour, which, in addition to the phenomenon of epibiosis on their exoskeleton, constitutes a complex camouflage system to ward off predators.

An improved non-invasive method for measuring heartbeat of intertidal animals [PDF]
Since its emergence two decades ago, the use of infrared technology for noninvasively measuring the heartbeat rates of invertebrates has provided valuable insight into the physiology and ecology of intertidal organisms.

Occurrence and mechanisms of ontogenetic changes in body colour lightness in intertidal marine invertebrates [PDF]
Ontogenetic changes in body colouration are known to occur in some benthic marine invertebrates and have been associated with ecological shifts in diet and physiological tolerance.
