“…Wang et al, 2016). Despite their prevalence (Almeida et al, 2021; Eyck et al, 2019), experiential legacies are not always considered when examining the impact of early life on individuals. This lack of attention to experiential legacies limits our understanding of how individual phenotypes, cohorts or populations respond to variable environments and potentially limits our ability to manage and conserve populations (O'Connor & Cooke, 2015; Van Allen & Rudolf, 2016).…”

Climate‐induced shifts in plankton blooms may alter fish recruitment by affecting the fatty acid composition of early‐life diets and corresponding performance. Early‐life nutrition may immediately affect survival but may also have a lingering influence on size and growth via experiential legacies. We explored the short‐ and longer‐term performance consequences of different concentrations of polyunsaturated fatty acids (PUFA) for juvenile Walleye (Sander vitreus, Mitchill 1818). For the first 10 days of feeding, juveniles were provided Artemia enriched with: oleic acid (low PUFA), high docosahexaenoic acid and high eicosapentaenoic acid (high PUFA), or high PUFA and a form of vitamin E (high PUFA + E). After 10 days, all fish were fed a high‐quality diet and reared for an additional 27 days. Juveniles fed either high PUFA diet were 1.15‐fold larger (PUFA mean ± SD = 20.0 ± 3.3 mg; PUFA + E = 19.8 ± 3.3 mg) than those fed the low PUFA (17.3 ± 2.8 mg) diet after 10 days of feeding. After 27 days, juveniles initially fed the high PUFA diet were still 1.10‐ to 1.20‐fold larger (PUFA = 407.0 ± 61.6 mg; PUFA + E = 422.7 ± 58.7 mg) than those initially fed the low PUFA diet (356.5.0 ± 39.5 mg). Our findings demonstrate that fatty acid composition of juvenile Walleye diets has immediate and lingering size effects. As changes in climate continue to alter lower trophic levels, fish management and conservation may need to consider short‐ and long‐term effects of temporal or spatial differences in early‐life diet quality.

Across diverse animal species, early-life experiences have lifelong impacts on a variety of traits. The scope of these impacts, their implications, and the mechanisms that drive these effects are central research foci for a variety of disciplines in biology, from ecology and evolution to molecular biology and neuroscience. Here we review the role of early-life in shaping adult phenotypes and fitness in bees, emphasizing the possibility that bees are ideal species to investigate the causes and consequences of variation in early-life experience at both individual and population levels. Bee early-life includes the larval and pupal stages, critical time periods during which factors like food availability, maternal care, and temperature set the phenotypic trajectory for an individual's lifetime. We discuss how some common traits impacted by these experiences, including development rate and adult body size, influence fitness at the individual level, with possible ramifications at the population level. Finally, we review ways in which human alterations to the landscape may impact bee populations through early-life effects. This review highlights aspects of bees’ natural history and behavioral ecology that warrant further investigation with the goal of developing a better understanding of the ways in which environmental disturbances threaten these vulnerable species.

Warming climates are creating unprecedented environmental conditions, such as more frequent and intense marine heatwaves (MHWs), that directly impact phenology and growth of fish and other marine organisms. Understanding individual phenological and growth responses to temperature is critical to predict species and population responses to climate change; however, doing so requires disentangling the effects of temperature on phenology, size, and growth in wild populations. We quantified the relationships between temperature and hatch timing, size-at-age, and early growth in a population of Pacific cod (Gadus macrocephalus) affected by recent MHWs in the Gulf of Alaska. Pacific cod juveniles were collected near Kodiak Island, Alaska, USA, across 11 years, categorized as before (2007, 2009–2010, 2012–2014), during (2015, 2016, 2019), and between (2017, 2018) multiple recent MHWs. We estimated age and growth with otolith structural analysis. Hatching occurred on average 14 days earlier during MHWs and 26 days earlier between than before MHWs. Approximately 53% and 16% of these respective shifts in timing were attributable directly to warmer temperatures during incubation. Size-at-age was similar across periods at younger ages (90 days), but approximately 7 mm and 11 mm larger than before MHWs at older ages (132 days) during and between MHWs, respectively. These differences in size-at-age were partially related to growth responses that differed among MHW periods. However, observed differences in growth rate could not account for the observed increases in size-at-age. We found that temperature alone could not explain the changes in growth and phenology; thus, factors such as parental effects, epigenetics, and selection likely contributed. Our results indicate that spawn timing, size, and growth relationships based on historical thermal responses should be questioned in population forecasting as the global climate continues to warm.
