Does early-life food shortage alter female life history at elevated temperatures?

Global warming is reducing food availability in many aquatic systems, raising questions about the combined effects of higher temperatures and lower food availability on fish life histories. In ectotherms, higher temperatures accelerate growth and promote an earlier onset of reproduction. However, when fish have less food during development, resource depletion might constrain these temperature-driven processes. We investigated how water temperature (24 or 28°C) and early-life food availability (control or restricted) affected adult life-history traits in female guppies (Poecilia reticulata).
