“…This is not an unusual finding as in many organisms maternal body size determines egg size and therefore the size of hatchlings [33–36]. A proximate explanation for this relationship might be morphological constraints, as the available body space might determine the overall egg volume that can be carried, or the size of the maternal organ through which eggs pass during oviposition might impose constraints [37]. Alternatively, there might be metabolic constraints such that the resource transport rate from the mother to the egg (e.g.…”

Despite a vast literature on the factors controlling adult size, few studies have investigated how maternal size affects offspring size independent of direct genetic effects, thereby separating prenatal from postnatal influences. I used a novel experimental design that combined a cross-fostering approach with phenotypic manipulation of maternal body size that allowed me to disentangle prenatal and postnatal maternal effects. Using the burying beetle Nicrophorus vespilloides as model organism, I found that a mother's body size affected egg size as well as the quality of postnatal maternal care, with larger mothers producing larger eggs and raising larger offspring than smaller females. However, with respect to the relative importance of prenatal and postnatal maternal effects on offspring growth, only the postnatal effects were important in determining offspring body size. Thus, prenatal effects can be offset by the quality of postnatal maternal care. This finding has implications for the coevolution of prenatal and postnatal maternal effects as they arise as a consequence of maternal body size. In general, my study provides evidence that there can be transgenerational phenotypic plasticity, with maternal size determining offspring size leading to a resemblance between mothers and their offspring above and beyond any direct genetic effects.

“…Such a relationship has previously been reported in other species, including Coleoptera (Fox, ; Kawecki, ; Guntrip et al ., ; Fox & Czesak, ; Fischer et al ., ; see also Kishi, ). In the seed beetle, Callosobruchus chinensis , this relationship was shown to be constrained by the width of the ovipositor (Yanagi & Tuda, ). Alternatively, smaller females with lower nutrient reserves may produce small eggs because of physiological constraints (Fox & Czesak, ).…”

“…In general, egg size is correlated with maternal body size (Fox & Czesak, 2000;Fischer et al, 2002). This relationship is probably derived from the width of the ovipositor (Yanagi & Tuda, 2012) or from the lower nutrient reserves of small females (Fox & Czesak, 2000). Similarly, old females or food-stressed females tend to produce smaller eggs than do young females (Fox, 1993a) or well-fed females (Fox, 1993a;Kyneb & Toft, 2006;Bauerfeind et al, 2007), respectively; this relationship probably reflects the depletion of resources for egg production (Wiklund et al, 1987;Fox & Czesak, 2000).…”

Variation in body size in the giant rhinoceros beetle Trypoxylus dichotomus is mediated by maternal effects on egg size

1. The egg size of insects can vary depending on maternal body size or resource status, and it may influence offspring body size by determining initial resource level. 2. The giant rhinoceros beetle Trypoxylus dichotomus exhibits considerable variation in body size, some of which is attributed to the variation in larval food (humus) quality, although a substantial amount of variation in body size remains unexplained. In the present study, changes in the egg size and offspring body size in response to several maternal variables were examined (i.e. body size, age, and, nutritional status). 3. Nutritional intake of the females during the adult stage did not affect the egg size. Larvae hatched from small eggs partially recovered from the initial disadvantage during their ontogenetic processes by increasing growth rate (i.e. compensatory growth); however, there was still a positive relationship between egg size and pupal body size. 4. Older females produced small eggs, but because of compensatory growth, the pupae were no longer small. By contrast, due to a lack of compensatory growth, small females produced small eggs as well as small pupae. 5. These results suggest that maternal body size affects offspring body size through effects on egg size. This transgenerational effect may account for some of the variation in adult body size of T. dichotomus.

Individual variation in resource acquisition should have consequences for life‐history traits and trade‐offs between them because such variation determines how many resources can be allocated to different life‐history functions, such as growth, survival and reproduction. Since resource acquisition can vary across an individual's life cycle, the consequences for life‐history traits and trade‐offs may depend on when during the life cycle resources are limited. We tested for differential and/or interactive effects of variation in resource acquisition in the burying beetle Nicrophorus vespilloides. We designed an experiment in which individuals acquired high or low amounts of resources across three stages of the life cycle: larval development, prior to breeding and the onset of breeding in a fully crossed design. Resource acquisition during larval development and prior to breeding affected egg size and offspring survival, respectively. Meanwhile, resource acquisition at the onset of breeding affected size and number of both eggs and offspring. In addition, there were interactive effects between resource acquisition at different stages on egg size and offspring survival. However, only when females acquired few resources at the onset of breeding was there evidence for a trade‐off between offspring size and number. Our results demonstrate that individual variation in resource acquisition during different stages of the life cycle has important consequences for life‐history traits but limited effects on trade‐offs. This suggests that in species that acquire a fixed‐sized resource at the onset of breeding, the size of this resource has larger effects on life‐history trade‐offs than resources acquired at earlier stages.
