With increasing age, the influence of light as a Zeitgeber decreased, while daily increments became more prominent in all environments. Temperature fluctuation affected increment appearance, but did not entrain increment deposition.- from Author13841552165-177eninfo:eu-repo/semantics/restrictedAccessAquatic Science/dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article
