“…The maternal effects on the growth strategy of clonal offspring Maternal effects have become an important field of study in ecology, and there is an ongoing debate regarding their adaptive significance for offspring fitness (Marshall and Uller, 2007). Maternal effects can be either adaptive if they increase offspring fitness or not if they are neutral or harmful to the fitness of offspring (Galloway and Etterson, 2007;Donelson et al, 2018;Zhou et al, 2021). In this study, the clonal offspring of different UV-B radiated parents displayed various performances, despite they were in an unirradiated environment (Tables 2, 3).…”

“…Maternal effects occur when the environment experienced by the mother influences the offspring phenotype over and above the direct effect of transmitted genes ( Marshall and Uller, 2007 ). Despite the importance of maternal effects has been confirmed by many studies ( Galloway and Etterson, 2007 ; Marshall and Uller, 2007 ; Auge et al, 2017b ; Lyu et al, 2017 ; Donelson et al, 2018 ; Zettlemoyer and Lau, 2021 ; Zhou et al, 2021 ), the adaptive significance of maternal effects is often controversial. Some studies have found that adaptive maternal effects are widespread, allowing offspring to cope with rapidly changing environments or even increase fitness ( Yin et al, 2019 ; Donelan et al, 2020 ).…”

Although there is an increasing debate about ecological consequences of environmental predictability for plant phenotype and fitness, the effect of predictability of parental environments on the offspring is still indefinite. To clarify the role of environmental predictability in maternal effects and the growth strategy of clonal offspring, a greenhouse experiment was conducted with Glechoma longituba. The parental ramets were arranged in three ultraviolet-B (UV-B) conditions, representing two predictable environments (regular and enhanced UV-B) and an unpredictable environment (random UV-B), respectively. The offspring environments were the same as their parent or not (without UV-B). At the end of experiment, the growth parameters of offspring were analyzed. The results showed that maternal effects and offspring growth were regulated by environmental predictability. Offspring of unpredictable environmental parents invested more resources in improving defense components rather than in rapid growth. Although offspring of predictable parents combined two processes of defense and growth, there were still some differences in the strategies between the two offspring, and the offspring of regular parent increased the biomass allocation to roots (0.069 g of control vs. 0.092 g of regular), but that of enhanced parent changed the resource allocation of nitrogen in roots and phosphorus in blade. Moreover, when UV-B environments of parent and offspring were matched, it seemed that maternal effects were not adaptive, while the growth inhibition in the predictable environment was weaker than that in unpredictable environment. In the predictable environment, the recovered R/S and the increased defense substances (flavonoid and anthocyanin) contributed to improving offspring fitness. In addition, when UV-B environments of parent and offspring were mismatched, offspring growth was restored or improved to some extent. The offspring performance in mismatched environments was controlled by both transgenerational effect and within-generational plasticity. In summary, the maternal effects affected growth strategies of offspring, and the differences of strategies depended on the predictability of parental UV-B environments, the clone improved chemical defense to cope with unpredictable environments, while the growth and defense could be balanced in predictable environments. The anticipatory maternal effects were likely to improve the UV-B resistance.

“…Understanding the adaptive response of organisms to changing environmental conditions is a major theme in ecology and evolutionary studies. A key component of this adaptability is phenotypic plasticity, which refers to the potential of an organism to change its phenotype in response to different environments, independent of their genotype (Donelan et al., 2020; O'Dea et al., 2016; West‐Eberhard, 2003; Zhou et al., 2022). By expressing plastic phenotypes, populations may experience lower demographic costs (Donelan et al., 2020).…”

“…By expressing plastic phenotypes, populations may experience lower demographic costs (Donelan et al., 2020). Albeit not genetically fixed, plastic changes of the phenotype can sometimes be transmitted to the next or multiple generation (inter‐ or transgenerational plasticity, ITGP) via the environment experienced by a parent influencing the development of their offspring (Latzel et al., 2023; Marshall & Uller, 2007; Puy et al., 2021; Wang et al., 2022; Zhou et al., 2022). Parents can change offspring phenotypes without affecting nucleotide sequence by multiple non‐genetic processes such as parental effects, for example, nutrient, hormone and protein transmission (Lacey, 1996; Zahra et al., 2021), or by epigenetic inheritance such as noncoding small RNAs, DNA methylation and histone modification (Danchin et al., 2011; Kong et al., 2020; Maury et al., 2019).…”

“…Such an ITGP can be adaptive only if it is anticipatory, and the parents modify the phenotype of their future offspring in response to changes in the present environment that also increase offspring fitness in its future environment (Marshall & Uller, 2007; examples in Latzel et al., 2023; Puy et al., 2021; Wang et al., 2022; Zhou et al., 2022). Such anticipatory parental effects are expected to occur in situations when the environmental conditions encountered by the offspring are sufficiently predictable from the parental environment or phenotype (Lind et al., 2020; Marshall & Uller, 2007).…”

While there is long‐standing interest in the role of inter‐ and transgenerational plasticity via the maternal line, it rarely has been studied via the paternal line. Thus, consequences of the paternal environment for parental fitness and for performance of offspring in the environments experienced by either fathers or mothers are not known. We studied the intergenerational plasticity (IGP) of the plant species Paeonia ostii (Paeoniaceae) and tested the hypothesis that exposure of fathers to environmental stress (i) reduces parental fitness and performance of offspring grown under non‐stressful conditions, but (ii) mitigates the negative effects of environmental stress on fitness of parents and performance of offspring. Crosses were made in a greenhouse within six families of P. ostii between parents grown under drought and in a mesic environment, and the offspring of each cross were grown under both dry and mesic conditions. Production and germination of seeds and morphological and physiological traits of offspring were measured as indicators of parental fitness and offspring performance, respectively. Paternal drought decreased seed number per fruit, except when maternal plants also were grown in drought conditions. Offspring drought decreased seedling performance. However, when fathers experienced drought this negative effect on the offspring was partly mitigated, in particular when mothers also had experienced drought. In contrast, offspring grown in mesic conditions had improved seedling performance, especially when either parent (or both) also were grown in mesic conditions. Such statistical differences remained when seed mass was included as a covariate. Overall, paternal pollen of P. ostii mediated IGP to drought almost as well as it did for maternal ovules. IGP was adaptive if environments remained constantly dry across generations but maladaptive if environments changed. Hence, under future climate changes, paternal IGP might be both a blessing and a curse, with the blessing occurring when the focal habitat becomes drier and pollen comes from already‐dry places, while the curse may dominate in predictably moist habitats surrounded by drier habitats.

Above–belowground insect herbivore interactions and plant compensatory growth are crucial for reshaping the fitness of invasive plants, and it is likely that climate warming, nitrogen (N) deposition, and plant provenance influence this interaction and growth in a complex way. We performed an experiment with Solidago canadensis from home and introduced ranges, leaf‐chewing Spodoptera litura, and root‐feeding Protaetia brevitarsis under climate warming and N deposition, and addressed how these abiotic stressors and plant provenance jointly shaped the reciprocal effects between S. litura and P. brevitarsis and the compensatory growth of S. canadensis after herbivory. Under ambient conditions, S. litura and P. brevitarsis inhibited each other on the basis of growth; warming, N addition or warming plus N addition shifted or even reversed this competition depending on provenance. While the survival‐based above–belowground interactions differed from growth‐based ones, warming or warming plus N addition also shifted or even reversed the neutralism or amensalism detected under ambient conditions depending on provenance. S. canadensis from its home range was more tolerant of herbivory than from its introduced range under ambient conditions; warming, N addition or warming plus N addition decreased the plant compensatory growth of native S. canadensis, but increased that of invasive S. canadensis relative to ambient conditions. These findings suggest that climate warming and N deposition could enhance positive above–belowground insect interactions, increasing insect pressures on S. canadensis, and that plant provenance might be important in mediating climate change effects on insect interactions and host compensatory growth under plant invasions.

Maternal effects of climate warming and nitrogen deposition vary with home and introduced ranges

Abstract: Maternal effects, which can be defined as the contribution of a maternal individual to the phenotype of its offspring beyond the equal chromosomal contribution, were identified as long ago as 1909 (Roach & Wulff, 1987). Since then, related studies have gained con-
