“…How can maternal effect mediate this growth‐survival trade‐off in offspring? One plausible explanation is that maternal effects may mediate the energy metabolism of offspring to reset the limitation of an energy budget, a rarely tested assumption underlying the energy allocation trade‐offs between growth and survival (Meter et al., 2020). Greater investment in growth leads to lower investment in immunity and repair of molecular damage associated with survival when total available energy is limited (Cichoń, 1997), but this trade‐off may disappear when energy is no longer a limiting factor.…”

“…In contrast, our results indicate that maternal effects can regulate this energy limitation. Therefore, we should pay more attention to the novel forces driving life‐history trade‐offs in a changing world, in addition to the energy allocation between life‐history traits, which is the focus of traditional life‐history studies (Meter et al., 2020). Moreover, our study demonstrates that maternal effects mediate the growth‐survival trade‐off of offspring, leading to time‐lagged responses of populations to climate warming due to delayed transgenerational effects (Beckerman et al., 2002; Plaistow et al., 2006).…”

As postulated by life‐history theory, not all life‐history traits can be maximized simultaneously. In ectothermic animals, climate warming is predicted to increase growth rates, but at a cost to overall life span. Maternal effects are expected to mediate this life‐history trade‐off, but such effects have not yet been explicitly elucidated. To understand maternal effects on the life‐history responses to climate warming in lizard offspring, we conducted a manipulative field experiment on a desert‐dwelling viviparous lacertid lizard Eremias multiocellata, using open‐top chambers in a factorial design (maternal warm climate and maternal present climate treatments × offspring warm climate and offspring present climate treatments). We found that the maternal warm climate treatment had little impact on the physiological and life‐history traits of adult females (i.e. metabolic rate, reproductive output, growth and survival). However, the offspring warm climate treatment significantly affected offspring growth, and both maternal and offspring warm climate treatments interacted to affect offspring survival. Offspring from the warm climate treatment grew faster than those from the present climate treatment. However, the offspring warm climate treatment significantly decreased the survival rate of offspring from maternal present climate treatment, but not for those from the maternal warm climate treatment. Our study demonstrates that maternal effects mediate the trade‐off between growth and survival of offspring lizards, allowing them to grow fast without a concurrent cost of low survival rate (short life span). These findings stress the importance of adaptive maternal effects in buffering the impact of climate warming on organisms, which may help us to accurately predict the vulnerability of populations and species to future warming climates.

“…At one extreme of the determinate-indeterminate growth continuum are determinate growers that preferentially allocate energy to growth in order to reach a final size as soon as possible (e.g. [66]), at the other extreme are species that delay skeletal maturity to such an extent that longitudinal growth cessation and GPC resorption is seldom, if ever, observed in natural populations (e.g. [67]).…”

Determinate growth is predominant and likely ancestral in squamate reptiles

Body growth is typically thought to be indeterminate in ectothermic vertebrates. Indeed, until recently, this growth pattern was considered to be ubiquitous in ectotherms. Our recent observations of a complete growth plate cartilage (GPC) resorption, a reliable indicator of arrested skeletal growth, in many species of lizards clearly reject the ubiquity of indeterminate growth in reptiles and raise the question about the ancestral state of the growth pattern. Using X-ray micro-computed tomography (µCT), here we examined GPCs of long bones in three basally branching clades of squamate reptiles, namely in Gekkota, Scincoidea and Lacertoidea. A complete loss of GPC, indicating skeletal growth arrest, was the predominant finding. Using a dataset of 164 species representing all major clades of lizards and the tuataras, we traced the evolution of determinate growth on the phylogenetic tree of Lepidosauria. The reconstruction of character states suggests that determinate growth is ancestral for the squamate reptiles (Squamata) and remains common in the majority of lizard lineages, while extended (potentially indeterminate) adult growth evolved several times within squamates. Although traditionally associated with endotherms, determinate growth is coupled with ectothermy in this lineage. These findings combined with existing literature suggest that determinate growth predominates in both extant and extinct amniotes.

“…The same reasoning was also applied to explain the ontogeny of sexual size dimorphism (SSD), the differences in size between sexes. The so-called “reproductive cost” hypothesis states that the allocation to growth should be smaller in the sex with higher reproductive cost ( Cox, 2006 ), i.e., that the amount of energy allocated to reproduction is directly traded-off with the allocation to growth (recently reviewed in Meter et al., 2020 ).…”

“… Cox and John-Alder, 2005 ; Cox and Calsbeek, 2010 ; Frynta et al., 2010 ). However, the reproductive cost hypothesis was not supported in experimental manipulations in Madagascar ground geckos ( Paroedura picta ) where females grew at the same rate and to the same final snout-vent length (SVL) regardless of the investment in fat reserves and egg production ( Kubička and Kratochvíl, 2009 ; Starostová et al., 2013 ; Kubička et al., 2017 ; reviewed in Meter et al., 2020 ).
