    • Abstract:
      An important goal of many studies in molecular ecology is to utilize molecular tools to elucidate how critical traits like metabolism and growth are affected by environmental stressors and how organisms offset these stresses by adaptive molecular-level responses. Stress from food deprivation may be critical for early developmental stages that require a continued supply of substrates for energy metabolism and growth if development is to be completed. In a 'From the Cover' article in this issue of Molecular Ecology, Li et al. (2023) examined the effects of withholding food (unicellular algae) on 10 traits of larvae of the purple sea urchin (Strongylocentrotus purpuratus), ranging from the molecular level (gene expression) to morphology. Overall, this study sheds new light on the plasticity of larval development and the tight linkages that exist among traits as they respond to changes in food availability. Importantly, shifts in the sources of food utilized under different dietary treatments show the plasticity of these larvae to alter reliance on endogenous energy stores and dissolved organic matter (DOM) as algae deprivation continues. The effects of global change on the amounts and phenology of productivity in the seas make this type of integrated, multi-level analysis an important tool for predicting the future states of marine ecosystems.
