When is warmer better? Disentangling within- and between-generation effects of thermal history on early survival

Understanding the fitness consequences of thermal history is necessary to predict organismal responses to global warming. This is especially challenging for ectotherms with complex life cycles, where distinct life stages can differ in thermal sensitivity, acclimate to different thermal environments, and accrue responses to acclimation within and between generations.
Although acclimation is often hypothesized to benefit organisms by helping them (or their offspring) to compensate for negative impacts of environmental change, mixed support for this hypothesis highlights the need to assess alternatives. Assessments that explicitly dissect responses across life stages and generations, however, remain limited. 
We assess alternative hypotheses of acclimation (none, beneficial, colder-is-better, and warmer-is-better) within and between generations of a marine tubeworm whose vulnerability to warming rests on survival at early planktonic stages (gametes, embryos, and larvae). First, we acclima..., ,
