Figure 6 in Nesting habits of the Japanese foliage spider, Cheiracanthium japonicum (Araneae: Miturgidae): host plant preference based on the physical traits of plant leaves
Figure 6. Differences in the nest size among all types examined by the Tukey test. A solid line indicates a range of 95% confidence intervals. If the interval crosses zero, the difference between the nest types is not significant. On the contrary, if the interval does not cross zero, the difference is significant. The nest types are abbreviated as follows: S1, season's first nest; S2, season's second nest; S3, season's third nest; S4, season's fourth nest; S5, season's fifth nest; M, mating nest; B, breeding nest.

Figure 5. Relationship between the nest size and the nest type (n = 167). The nest types are abbreviated as follows: S1, season's first nest; S2, season's second nest; S3, season's third nest; S4, season's fourth nest; S5, season's fifth nest; M, mating nest; B, breeding nest.
Figure 4 in Nesting habits of the Japanese foliage spider, Cheiracanthium japonicum (Araneae: Miturgidae): host plant preference based on the physical traits of plant leaves
Figure 4. Principal component analysis bi-plot of relationships between the four physical traits of a leaf and the nest type (n = 133). Physical traits are shown by vectors. Each plot represents a nest type: square: season's first nest; diamond: season's second nest; solid square: season's third nest; circle: season's fourth nest; solid circle: season's fifth nest; triangle: mating nest; solid triangle: breeding nest. Plots with similar physical traits are formed into three groups (A, B and C) surrounded by lines.

Data from: Preference for outbred host plants and positive effects of inbreeding on egg survival in a specialist herbivore
Inbreeding can profoundly affect the interactions of plants with herbivores as well as with the natural enemies of the herbivores. We studied how plant inbreeding affects herbivore oviposition preference, and whether inbreeding of both plants and herbivores alters the probability of predation or parasitism of herbivore eggs. In a laboratory preference test with the specialist herbivore moth Abrostola asclepiadis and inbred and outbred Vincetoxicum hirundinaria plants, we discovered that herbivores preferred to oviposit on outbred plants. A field experiment with inbred and outbred plants that bore inbred or outbred herbivore eggs revealed that the eggs of the outbred herbivores were more likely to be lost by predation, parasitism or plant hypersensitive responses than inbred eggs. This difference did not lead to differences in the realized fecundity as the number of hatched larvae did not differ between inbred and outbred herbivores. Thus, the strength of inbreeding depression in herbivores decreases when their natural enemies are involved. Plant inbreeding did not alter the attraction of natural enemies of the eggs. We conclude that inbreeding can significantly alter the interactions of plants and herbivores at different life-history stages, and that some of these alterations are mediated by the natural enemies of the herbivores.
Data from: Insect mating signal and mate preference phenotypes covary among host plant genotypes
Sexual selection acting on small initial differences in mating signals and mate preferences can enhance signal-preference co-divergence and reproductive isolation during speciation. However, the origin of initial differences in sexual traits remains unclear. We asked whether biotic environments, a source of variation in sexual traits, may provide a general solution to this problem. Specifically, we asked whether genetic variation in biotic environments provided by host plants can result in signal-preference phenotypic covariance in a host-specific, plant-feeding insect. We used a member of the Enchenopa binotata species complex of treehoppers (Hemiptera: Membracidae) to assess patterns of variation in male mating signals and female mate preferences induced by genetic variation in host plants. We employed a novel implementation of a quantitative genetics method, rearing field-collected treehoppers on a sample of naturally-occurring replicated host plant clone lines. We found remarkably high signal-preference covariance among host plant genotypes. Thus, genetic variation in biotic environments influences the sexual phenotypes of organisms living on those environment in a way that promotes assortative mating among environments. This consequence arises from conditions likely to be common in nature (phenotypic plasticity and variation in biotic environments). It therefore offers a general answer to how divergent sexual selection may begin.
Data from: Female fecundity variation affects reproducibility of experiments on host plant preference and acceptance in a phytophagous insect
Reproducibility is a scientific cornerstone. Many recent studies, however, describe a reproducibility crisis and call for assessments of reproducibility across scientific domains. Here, we explore the reproducibility of a classic ecological experiment—that of assessing female host plant preference and acceptance in phytophagous insects, a group in which host specialization is a key driver of diversification. We exposed multiple cohorts of Pieris napi butterflies from the same population to traditional host acceptance and preference tests on three Brassicaceae host species. Whereas the host plant rank order was highly reproducible, the propensity to oviposit on low-ranked hosts varied significantly even among cohorts exposed to similar conditions. Much variation could be attributed to among-cohort variation in female fecundity, a trait strongly correlated both to female size and to the size of the nuptial gift a female receives during mating. Small males provide small spermatophores, and in our experiment small females that mated with small males had a disproportionally low propensity to oviposit on low-ranked hosts. Hence, our results provide empirical support to the theoretical prediction that female host utilization is strongly affected by non-genetic, environmental variation, and that such variation can affect the reproducibility of ecological experiments even under seemingly identical conditions.
