“…In the crustacean Daphnia, brood pouch size limits offspring size, even if large offspring size is favorable under certain environmental conditions (Robertson, 1988). In many lepidopteran insects, egg size decreases with age (Murphy et al, 1983;Karlsson and Wiklund, 1984, p. 84;Yanagi and Miyatake, 2002;Giron and Casas, 2003), suggesting that it is constrained by impoverished resources of aging mothers (the partial resource depletion hypothesis: Wiklund and Karlsson, 1984). Minimum egg size is also likely to be constrained by fitness attributes such as the ability of hatchlings to capture prey (Stewart et al, 1991) or to begin feeding.…”

The tradeoff between offspring size and number is ubiquitous and manifestly similar in plants and animals despite fundamental differences between the evolutionary histories of these two major life forms. Fecundity (offspring number) primarily affects parental fitness, while offspring size underpins the fitness of parents and offspring. We provide an overview of theoretical models dealing with offspring size and fitness relationships. We follow that with a detailed examination of life-history constraints and environmental effects on offspring size and number, separately in plants and animals. The emphasis is on seed plants, but we endeavor to also summarize information from distinct animal groups-insects, fishes, reptiles, birds, and mammals. Furthermore, we analyse genetic controls on offspring size and number in two model organisms-Arabidopsis and Drosophila. Despite the deep evolutionary divergence between plants and animals, we find four trends in reproductive strategy that are common to both lineages: (i) offspring size is generally less variable than offspring number, (ii) offspring size increases with increasing parent body size, (iii) maternal genes restrict offspring size and increase offspring numbers, while zygotic genes act to increase offspring size; such parent-offspring conflicts are enhanced when there is sibling rivalry, and (iv) variation in offspring size increases under sub-optimal (harsh) environmental conditions. The most salient difference between plants and animals is that the latter tend to produce larger (fewer) offspring under sub-optimal conditions while seed plants invest in smaller (many) seeds, suggesting that maternal genetic control over offspring size increases in plants but decreases in animals with parental care. The time is ripe for greater experimental exploration of genetic controls on reproductive allocation and parent-offspring conflicts in plants and animals under sub-optimal (harsh) environments.

“…On the first day the females laid eggs, three eggs were randomly chosen and frozen because the egg size decreases with maternal age (Yanagi and Miyatake 2002). The egg size was measured on a seed using an optical micrometer on a 409 stereomicroscopic monitoring system (VM-60, Olympus, Tokyo, Japan).…”

Usually, several traits in organisms are genetically linked with each other; thus, correlated responses to selection are generally observed. Anti-predator behaviors may be genetically correlated with other traits such as life-history. We compared the life-history traits of individuals derived from two regimes artificially selected for the duration of death feigning in the adzuki bean beetle, Callosobruchus chinensis. The two-way selected regimes include the L-lines with stronger intensity (longer duration and higher frequency) and the S-lines with weaker intensity (shorter duration and lower frequency) of death feigning. L-lines exhibited greater longevity, higher rates of emergence, laid bigger eggs and greater reproductive effort, and also had a tendency of faster development. Fecundity was not significantly different between L-and S-lines. These results provide the novel possibility that death feigning is a potentially advantageous anti-predator behavior that, through a positive genetic correlation with some life-history traits, can bring a higher fitness to an individual adopting this behavior. This novel aspect might explain why deathfeigning behavior is prevalent in various taxonomic animal groups.

“…This suggests that, when not adequately fed, females may run short of some specific nutrients initially available from larval stores, which are required to ensure maximum hatching success (see also Fox, 1993;Yanagi and Miyatake, 2002). Adequate nutrition is provided by banana, but more interestingly also by sugar solutions supplemented with liposomes (probably serving as a source of phospholipids), PUFAs (though it cannot be distinguished whether this effect is due to liposomes or the provided PUFAs per se), ethanol and yeast.…”

It was generally believed that butterflies and other holometabolous insects rely primarily on reserves accumulated during the larval stage for reproduction. Recent studies, however, highlight the often fundamental importance of adult nutrition to realize the full reproductive potential. While the importance of carbohydrates is fairly well understood, the role of most other adult-derived substances is only partially resolved. We here focus on the effects of dietary lipids (cholesterol, polyunsaturated fatty acids) and fruit decay (dietary yeast, ethanol) on female reproduction in the tropical, fruit-feeding butterfly Bicyclus anynana (Nymphalidae). We found that banana-fed control females outperformed all other groups fed on sucrose-based diets. Lipids, yeast or ethanol added to a sugar solution did not yield a similarly high reproductive output compared to fruit-fed females. Groups fed fresh or decaying banana showed no differences in reproductive performance. As we could not identify a single pivotal substance, we conclude that resource congruence (the use of nutrient types in a specified ratio) rather than any specific nutrient component is of key importance for maximum reproductive output. Further, dietary quality may affect egg hatching success in spite of no obvious effects on egg size and number. Thus, any implications about potential fitness effects of different diets need to consider egg (and hatchling) viability in addition to fecundity. r
