ABSTRACT Climate change is altering temperature means and variation, both need to be considered in predictions underpinning conservation. However, there no consensus the literature regarding effects of fluctuations on biological functions. Fluctuations may affect responses because inequalities from non‐linear responses, endocrine regulation or exposure damaging temperatures. Here we establish current state knowledge how impact within individuals populations compared constant temperatures with same mean. We conducted a meta‐analysis 143 studies ectothermic animals (1492 effect sizes, 118 species). In this study, 89% sizes were derived diel cycles, but significant differences between cycles shorter (<8 h) longer (>48 their responses. show that have little overall trait mean variance. Nonetheless, can stressful: increased ‘gene expression’ aquatic animals, which was driven mainly by hsp70. Fluctuating also decreased longevity, amplitudes had negative population organisms. conclude extreme events such as heat waves are important consider, regular (particularly diel) less so.

Hormones regulate most physiological functions and life history from embryonic development to reproduction. In addition their roles in growth development, hormones also mediate responses the abiotic, social nutritional environments. Hormone signalling is responsive environmental changes adjust phenotypes prevailing conditions. Both hormone levels receptor densities can change provide a flexible system of regulation. Endocrine flexibility connects environment organismal function, it central understanding impacts effect on individuals populations. may act as 'sensor' link signals epigenetic processes thereby phenotypic plasticity within across generations. Many parameters are now changing unprecedented ways result human activity. The knowledge base organism-environmental interactions was established environments that differ many current conditions ongoing impacts. It an urgent contemporary challenge understand how evolved endocrine will modulate response anthropogenic including climate change, light-at-night chemical pollution. play role ecology, integration into conservation lead more effective outcomes. This article part theme issue 'Endocrine variation: conceptual approaches recent developments'.
