“…While we focus primarily on temperature, global climate change is also altering a variety of biotic and abiotic gradients [123] and endocrine flexibility likely plays a role in responding to each of these. The field stands at an exciting crossroads, and there are many opportunities to establish connections between endocrine flexibility and the approaches and techniques employed in recent studies of behavioural, phenological or morphological responses to climate change [6,10,12,100,124]. Whether similar eco-geographic patterns exist for endocrine flexibility and whether those patterns are changing predictably with climate change is an open question.…”

Global climate change has increased average environmental temperatures world-wide, simultaneously intensifying temperature variability and extremes. Growing numbers of studies have documented phenological, behavioural and morphological responses to climate change in wild populations. As systemic signals, hormones can contribute to orchestrating many of these phenotypic changes. Yet little is known about whether mechanisms like hormonal flexibility (reversible changes in hormone concentrations) facilitate or limit the ability of individuals, populations and species to cope with a changing climate. In this perspective, we discuss different mechanisms by which hormonal flexibility, primarily in glucocorticoids, could promote versus hinder evolutionary adaptation to changing temperature regimes. We focus on temperature because it is a key gradient influenced by climate change, it is easy to quantify, and its links to hormones are well established. We argue that reaction norm studies that connect individual responses to population-level and species-wide patterns will be critical for making progress in this field. We also develop a case study on urban heat islands, where several key questions regarding hormonal flexibility and adaptation to climate change can be addressed. Understanding the mechanisms that allow animals to cope when conditions become more challenging will help in predicting which populations are vulnerable to ongoing climate change. This article is part of the theme issue ‘Endocrine responses to environmental variation: conceptual approaches and recent developments’.

“…This is despite the fact that life‐history strategies and responses to food availability can vary dramatically across populations of a single species (e.g., Gamelon et al., 2021; Nilsen et al., 2009). A more thorough look at among‐population variation in traits and responses to environmental change may identify important axes of covariation in population sensitivity to environmental variation (Vriend et al., 2023). Another thing that remains to be seen is whether the differences in previous studies the authors observe in life‐history responses to environmental change is due to the use of mechanistic demographic models or are, at least in part, due to using aquatic species, which have been shown to employ different strategies compared with terrestrial animals to respond to environmental change (Capdevila et al., 2020).…”

Research Highlight: Rademaker, M., van Leeuwen, A., & Smallegange, I. M. (2024). Why we cannot always expect life history strategies to directly inform on sensitivity to environmental change. Journal of Animal Ecology, https://doi.org/10.1111/1365‐2656.14050. Ecological studies have long delved into how organisms allocate energy between reproduction and somatic maintenance to maximize fitness. This allocation gives rise to various life‐history strategies, and these strategies have been shown to predict how populations respond to environmental change, allowing us to generalize potential responses to increasing human pressures. Such predictions have, however, been made for a limited set of terrestrial taxa and typically do not explore how individual differences in life‐history responses to environmental change scale to affect population‐level responses. Using novel data on diverse fish species, Rademaker et al. (2024) construct models that link individual‐level trade‐offs in energy allocation under environmental change to population‐level life‐history strategies. A key finding in their study is that short‐lived species are not more sensitive to environmental change—unlike results of previous studies. This study represents a new generation of work that underscores the complexity of predicting population responses to environmental shifts and suggests a need for a broader understanding of individual‐level mechanisms. The results of Rademaker et al. (2024) encourage further mechanistic life‐history analyses across a wider range of species and populations to validate the exciting findings and explore their implications across diverse ecological contexts.

“…Spatial synchrony can be important for population stability (Paradis 1997;Ruxton 1994), but highly synchronous dynamics may impose a risk of species extinction if density crashes occur simultaneously (Heino et al 1997). Research has identified spatial synchrony in survival (Olmos et al 2020), body mass (Herfindal et al 2020), breeding success (Olin et al 2020;Vriend et al 2023), phenological timing (Vriend et al 2023), and population size (Bjørnstad et al 1999a;Hansen et al 2020;Koenig 1999), particularly in birds (Mortelliti et al 2015;Paradis et al 1999Paradis et al , 2000Saether et al 2007). However, despite the interrelated dynamics between variation in population growth and age structure, there has been little research into spatial synchrony of age structure and the mechanisms that might drive this.…”

Spatio-temporal variation in age structure influences population dynamics, yet we have limited understanding of the spatial scale at which its fluctuations are synchronised between populations. Using 32 great tit populations, spanning 3200km and>130,000 birds across 67 years, we quantify spatial synchrony in breeding age structure and its drivers. We show that larger clutch sizes, colder winters and summers, and larger beech crops lead to younger populations. We report distant-dependent spatial synchrony of age structure, which is maintained at approximately 650km. Despite covariation with age structure, reproductive and environmental variables do not influence the scale of synchrony, except for a moderate effect of beech masting. We suggest that local ecological and density-dependent dynamics impact how environmental variation interacts with age structure, influencing estimates of the environment’s effect on spatial synchrony. Our analyses demonstrate the operation of synchrony in age structure over large scales, with implications for age-dependent demography in populations.
