“…host plants (Hughes & Vogler 2004;Carroll et al 2005) exist, our results are the first to demonstrate that geographically structured coevolution can cause substantial intraspecific variation in the allometric equations of exaggerated insect traits. Therefore, our results indicate that the geographic mosaic of species interactions (Thompson 1999) provides an excellent framework for determining the trajectory of escalating coevolution.…”

Coevolution of exaggerated morphologies between insects and plants is a well-known but poorly understood phenomenon in evolutionary biology. In the antagonistic interaction between a seed-predatory insect, the camellia weevil (Curculio camelliae), and its host plant, Japanese camellia (Camellia japonica), we examined the evolutionary trajectory of an exaggerated offensive trait of the weevil (rostrum length) in terms of scaling relationship. Sampling throughout Japan revealed that the ratio of the rostrum length to overall body size was correlated with the ratio of the pericarp thickness to overall fruit size across the localities. We found a geographical interpopulation divergence in a parameter pertaining to the allometric equation of rostrum length (the coefficient a in yZax b , where y and x denote rostrum and body lengths, respectively), and the pattern of geographical differentiation in the allometric coefficient was closely correlated with the variation in the pericarp thickness of Japanese camellia. Our results provide a novel example of a geographically diverged scaling relationship in an insect morphology resulting from a coevolutionary arms race with its host plant.

“…For example, introduced toads in Australia [14] and Chinook salmon in New Zealand [13] display adaptive evolution in dispersal and reproductive traits tied to population vital rates. Native species can also evolve quickly [9], but what remains to be seen is whether adaptive responses by natives will be sufficient to allow them to persist [67] or even flourish [68] in an increasingly homogenized global biotic community. …”

Fine-scale local adaptation in an invasive freshwater fish has evolved in contemporary time

Adaptive evolutionary change in only a few generations can increase the ability of non-native invasive species to spread, and yet adaptive divergence is rarely assessed in recently established populations. In this study, we experimentally test for evidence of fine-scale local adaptation in juvenile survival and growth among three populations of an invasive freshwater fish with reciprocal transplants and common-garden experiments. Despite intrinsic differences in habitat quality, in two of three populations we detected evidence of increased survival in 'home' versus 'away' environments with a Bayesian occupancy model fitted to mark -recapture data. We found support for the 'local' versus 'foreign' criterion of local adaptation as 14 of 15 pairwise comparisons of performance were consistent with local adaptation ( p , 0.001). Patterns in growth were less clear, though we detected evidence of location-and population-level effects. Although the agents of divergent ecological selection are not known in this system, our results combine to indicate that adaptive divergence-reflected by higher relative survival of local individuals-can occur in a small number of generations and only a few kilometres apart on the landscape.

“…An alternative cause of the complex genetic population structure found in some forms of Junonia is that these species, which are defined on the basis of morphology and colour patterns, may include races that are specializing on different larval host plants. Host plant specialization is a widespread mechanism for population differentiation causing rapid evolution of adaptive traits for feeding on new hosts and for assortative mating to maintain favourable combinations of traits [109][110][111][112][113]. In some cases, it has been suggested that this has been a driver for reproductive isolation and incipient speciation in many insects [113][114][115][116][117].…”

Up to 9 described species of Junonia butterflies occur in the Americas, but authorities disagree due to species similarities, geographical and seasonal variability, and possible hybridization. In dispute is whether Caribbean Junonia are conspecific with South American species. Cytochrome oxidase I (COI) barcodes, wingless (wg) sequences, and Randomly Amplified Fingerprints (RAF) were studied to reveal Junonia population structure in French Guiana, Guadeloupe, Martinique, and Argentina. Phylogenetic analysis of COI recovered 2 haplotype groups, but most Junonia species can have either haplotype, so COI barcodes are ambiguous. Analysis of nuclear wingless alleles revealed geographic patterns but did not identify Junonia species. Nuclear RAF genotyping distinguished 11 populations of Junonia arranged into 3 clusters. Gene flow occurs within clusters but is limited between clusters. One cluster included all Argentinian samples. Two clusters included samples from French Guiana, Martinique, and Guadeloupe and appear to be divided by larval host plant use (Lamiales versus Scrophulariales). Many Junonia taxa were distributed across populations, possibly reflecting patterns of genetic exchange. We had difficulty distinguishing between the Caribbean forms J. zonalis and J. neildi, but we demonstrate that Caribbean Junonia are genetically distinct from South American J. evarete and J. genoveva, supporting the taxonomic hypothesis that they are heterospecific.
