Abstract Global warming is reducing prey availability in many aquatic systems, raising questions about the combined effects of higher temperatures and lower food on fish life histories reproductive output. In ectotherms, accelerate growth promote an earlier onset reproduction. However, when have less during development, resource depletion might constrain these temperature-driven processes. We manipulated water temperature (24 or 28°C) early-life (control restricted) for female guppies ( Poecilia reticulata ). measured how both factors affected key history traits (growth, reproduction, survival, self-maintenance). Higher significantly histories. Females at 28°C matured a larger size, but then grew more slowly produced fewer, smaller offspring than females 24°C. The effect reproduction persisted even after controlling body suggesting there was shift fecundity-size relationship. Adult mortality greater 28°C. also resulted longer gut, potentially enhancing acquisition, did not affect immunity telomere length surviving females. Early-life shortage very few traits, except weak interaction with that total fecundity. At 28°C, experienced restriction fewer continual supply. No such diet occurred Our results suggest tropical may be severely impacted by increased (i.e., decreased morality), are likely to resilient brief periods limitations early development.

Abstract The pace of life (POL) is shaped by a complex interplay between genetic and environmental factors, influencing growth, maturation, lifespan across species. Hippo signaling pathway, key regulator organ size cellular homeostasis, has emerged as central integrator cues that modulate POL traits. In this review, we explore how the pathway links factors—such temperature fluctuations dietary energy availability—to molecular mechanisms governing metabolic balance, hormonal signaling, reproductive timing. Specifically, highlight regulatory interactions sensors (AMPK, mTOR, SIRT1 DLK1-Notch), well signals (IGF-1, kisspeptin, leptin, cortisol, thyroid sex steroids), which together orchestrate life-history traits, including growth rates, sexual with particular emphasis on their role in Furthermore, consider its potential coordinator POL-related processes, such telomere dynamics epigenetic mechanisms, within broader network. By integrating insights from biology eco-evolutionary perspectives, propose future directions to dissect pathway’s regulation taxa. Understanding these will provide new perspectives organisms adaptively adjust strategies response variability.
