Data from: Evolution under dietary restriction increases male reproductive performance without survival cost
Dietary restriction (DR), a reduction in nutrient intake without malnutrition, is the most reproducible way to extend lifespan in a wide range of organisms across the tree of life, yet the evolutionary underpinnings of the DR effect on lifespan are still widely debated. The leading theory suggests that this effect is adaptive and results from reallocation of resources from reproduction to somatic maintenance in order to survive periods of famine in nature. However, such response would cease to be adaptive when DR is chronic and animals are predicted to allocate more resources to reproduction. Nevertheless, chronic DR can also increase the strength of selection resulting in the evolution of more robust genotypes. We evolved Drosophila melanogaster fruitflies on 'DR', 'standard' and 'high' adult diets in replicate populations with overlapping generations. After ~25 generations of experimental evolution, male 'DR' flies had higher fitness than males from 'standard' and 'high' populations. Strikingly, this increase in reproductive success did not come at a cost to survival. Our results suggest that sustained DR selects for more robust male genotypes, which are overall better able to convert resources into energy, which they allocate mostly to reproduction.
Fitness implications of nonlethal injuries in scorpions: females, but not males pay reproductive costs
<p>The ability to detach a body part in response to a predation attempt is known as autotomy, and it is perhaps the most intensively studied form of nonlethal injury in animals. Although autotomy enhances survival, it may impose reproductive costs to both males and females. We experimentally investigated how autotomy affects the reproductive success of males and females of a scorpion species. Individuals of Ananteris balzani autotomize the last abdominal segments ("tail"), losing the anus and leading to lifelong constipation since regeneration does not occur. Although male "tail" is used during courtship and sperm transfer, autotomy had no effect on male mating success. The combined effect of increased mortality and reduced fecundity resulted in autotomized females producing nearly 35% less offspring than intact females. In conclusion, the negative effects of "tail" autotomy are clearly sex-dependent, probably because the factors that influence reproductive success in males and females are markedly different.</p>
Data from: Experimental evidence of early costs of reproduction in conspecific viviparous and oviparous lizards
Reproduction entails costs, and disentangling the relative importance of each stage of the reproductive cycle may be important to assess the costs and benefits of different reproductive strategies. We studied the early costs of reproduction in oviparous and viviparous lizard females of the bimodal reproductive species Zootoca vivipara. Egg-retention time in oviparous females is approximately one third of the time in viviparous females. We compared the vitellogenesis and egg-retention stages which are common to both reproductive modes. Precisely, we monitored the thermoregulatory behaviour, the weight gain and the immunocompetence of the females. Moreover, we injected an antigen in half of the females (immune challenge) to study the trade-offs between reproductive mode and immune performance, and between different components of the immune system. Finally, we experimentally induced parturition in viviparous females at the time of egg-laying in oviparous females. Oviparous and viviparous females did not show strong differences in response to the immune challenge. However, viviparous females spent more time thermoregulating while partially hidden and gained more weight than oviparous females. The greater weight gain indicates that the initial period of egg-retention is less costly for viviparous than for oviparous females or that viviparous females are able to save and accumulate energy at this period. This energy may be used by viviparous females to cope with the subsequent costs of the last two thirds of the gestation. Such an ability to compensate the higher costs of a longer egg-retention period may account for the frequent evolution of viviparity in squamate reptiles.
Data from: The jack-of-all-trades is master of none: a pathogen's ability to infect a greater number of host genotypes comes at a cost of delayed reproduction.
A trade-off between a pathogen's ability to infect many hosts and its reproductive capacity on each host genotype is predicted to limit the evolution of an expanded host range, yet few empirical results provide evidence for the magnitude of such trade-offs. Here, we test the hypothesis for a trade-off between the number of host genotypes that a fungal pathogen can infect (host genotype range) and its reproductive capacity on susceptible plant hosts. We utilized strains of the oat crown rust fungus that carried widely varying numbers of virulence (avr) alleles known to determine host genotype range. We quantified total spore production and the expression of four pathogen life history stages: infection efficiency, time until reproduction, pustule size, and spore production per pustule. In support of the trade-off hypothesis, we found that virulence level, the number of avr alleles per pathogen strain, was correlated with significant delays in the onset of reproduction and with smaller pustule sizes. Modeling from our results, we conclude that trade-offs have the capacity to constrain the evolution of host genotype range in local populations. In contrast, long term trends in virulence level suggests that the continued deployment of resistant host lines over wide regions of the USA has generated selection for increased host genotype range.
