    Abstract The genus Carabus (Coleoptera: Carabidae: Carabinae) is a group of predacious ground beetles found throughout Holarctic temperate zones. The diversification of this group is attributed not only to allopatric speciation but also to diversification in life-history traits and morphological traits that are involved in ecological adaptation and reproductive isolation. Precise phylogenetic reconstruction of Carabus is important to understanding the factors associated with species’ divergence in relation to such character divergence. Here, we analyse the phylogeny of Carabus among higher taxonomic groups and among species of the subgenus Apotomopterus, a hyper-diverse group endemic to East Asia. We used genome-wide sequence data from ultraconserved elements for phylogenetic reconstruction via maximum-likelihood and species-tree reconstruction methods. With regard to the relationships among higher taxonomic groups, the obtained phylogenetic trees resolved two structures with previously unresolved divergence. The subgenus Apotomopterus contained three lineages, i.e. the Vitalisi, Prodigus, and Sauteri groups. It showed diversification of the spinula, a sclerotized male genital structure, and variation in the female elytral notch (preapical emargination). These morphological traits may be involved in copulatory behaviour and potentially affect reproductive isolation, and their character state divergence may have facilitated species divergence of Apotomopterus.

    Abstract Changes in the morphology, physiology and behavior of parasitized organisms provide an ideal opportunity to examine the extended phenotype of parasites. Since the quality of the host directly affects the fitness of the parasite, parasites may increase their fitness by manipulating phenotypes of low-quality hosts. Males are usually preyed on by females in sexual cannibalism. Thus, the males of sexually cannibalistic species are unsafe and low-quality hosts for parasites, while females may be beneficial hosts because of the chance of nutrient intake from cannibalized males. Under passive modes of transmission, parasites cannot choose the host sex. Such parasites exploiting sexually cannibalistic organisms are subjected to contrasting fitness effects and may evolve to manipulate host mating behavior in a sex-specific manner: decreasing male mating to avoid cannibalism and promoting female mating to engage in cannibalism. We examined this hypothesis by a behavioral experiment using a mantid-hairworm system. Parasitized male mantids (Tenodera angustipennis) changed their behavior as expected, exhibiting increased escapes and decreased courtships and mountings, potentially avoiding encounters with the female. Interestingly, male attack behavior was promoted, possibly decreasing contact with the encountered female. However, contrary to our prediction, parasitized females also exhibited decreased propensities of mating, suggesting costs or little benefits of host mating for parasites in the female host. This study provides novel insights into the evolution of parasite strategies in response to sexual differences in host quality.

    Abstract In reproductive interference (RI), the fitness of individuals or populations is decreased through reproductive interactions with other species. This process results in positive frequency dependence, hindering species coexistence. However, theory predicts that species can coexist under weak RI. Habitat segregation can decrease the opportunity for reproductive interactions between species. Thus, a difference in habitat preference between species may weaken RI and facilitate coexistence. We examined this hypothesis by investigating the habitat uses of closely related Ohomopterus ground beetle species under RI, Carabus insulicola and C. esakii, in limited zones of sympatry at their distributional boundary. The effect of RI may be stronger for females of C. esakii than those of C. insulicola due to asymmetry in the genital size mismatch between the species (C. insulicola males have larger genitalia). Field surveys of local abundances and associations with local environmental parameters revealed contrasting habitat uses between the species. C. insulicola preferred open environments, while C. esakii inhabited forest environments. Interestingly, the habitat use of C. esakii, not C. insulicola, changed depending on the frequency of the other species; the species utilized habitats with a low frequency of C. insulicola. The difference in habitat use and its dependence on the frequency of the other species may facilitate species coexistence by promoting habitat segregation within a continuous landscape. Our findings provide insights into the importance of (plastic) trait differences in species distributions and coexistence under RI.

    Abstract Extensive research in evolutionary biology has focused on the exaggeration of sexual traits; however, the developmental basis of exaggerated sexual traits has only been determined in a few cases. The evolution of exaggerated sexual traits may involve the relaxation of constraints or developmental processes mitigating constraints. Ground beetles in the subgenus Ohomopterus (genus Carabus) have species‐specific genitalia that show coevolutionary divergence between the sexes. Here, we examined the morphogenesis of the remarkably enlarged male and female genitalia of Carabus uenoi by X‐ray microcomputed tomography. The morphogenetic processes generating the male and female genitalia at the pupal stage were qualitatively similar to those in closely related species with standard genital sizes. Higher growth rates contributed to the exaggeration of both the male and female genital parts of C. uenoi, possibly related to a gene network commonly upregulated in both sexes. Additionally, the length of the copulatory piece (CP), the enlarged male genital part stored in the aedeagus (AD), reached close to that of the AD at the later developmental stages and thereafter decelerated to grow in parallel with the AD, suggesting a structural constraint on the CP by the outer AD. Then, unlike related species, the lengths of the CP and AD increased at eclosion, suggesting a mechanism leading to further elongation of the male genitalia. These observations suggest that a developmental process allows continuous growth of the male genitalia even under the spatial limitation. These results revealed the spatio‐temporal dynamics of the development of exaggerated genital structures under structural constraints.

    Abstract Natural selection against maladaptive interspecific reproductive interactions may cause greater divergence in mating traits between sympatric populations than between allopatric populations in a pair of species, known as reproductive character displacement (RCD) which is evidence for the lock-and-key hypothesis of genital evolution. However, the relative importance of various processes contributing to RCD in genital morphology (e.g. reinforcement, reproductive interference, and population filtering or the Templeton effect) is not clear. Here, we examined hypotheses for RCD in genital morphology, with a special focus on the Templeton effect (which predicts that only highly differentiated populations can exist in sympatry). We examined population-level fitness costs in interspecific mating between Carabus maiyasanus and Carabus iwawakianus with RCD in genital morphology. A mating experiment using populations with various degrees of RCD in genital morphology showed no evidence for consistently lower interspecific mating costs in C. maiyasanus populations in contact with displacement in genital morphology than in remote populations, contrary to the predictions of the Templeton effect. Alternatively, interspecific mating costs varied among populations. Observed relationships between the sizes of genital parts concerning isolation and interspecific mating costs across populations suggested that population-level fitness costs do not necessarily decrease during the process leading to RCD. Our results provide insight into ecological and evolutionary processes during secondary contact in closely related species.

    Spatial and temporal variation in ecological environments may result in spatial and temporal variation in communities. Temporal studies of biodiversity are essential for forecasting future changes in community structure and ecosystem function. Therefore, determining the mechanisms that drive temporal change in communities remains an important and interesting challenge in ecology. We quantified spatial and temporal variations in carabid beetle communities and site-specific environmental factors for 5 years at nine study sites on three mountains in the Baekdudaegan Mountain Range, Korea. Carabid beetle communities exhibited significant temporal variation, which was larger than spatial variations between and within mountains. Environmental factors mostly varied between sites within mountains. Community variation was only weakly associated with environmental factors at wide scales, i.e., between sites on three mountains, but was strongly associated at narrow spatial scales, i.e., between sites within one mountain. Our results indicate that temporal variation in communities occurs in response to variations in the local climate, and that the patterns of temporal variation differ between mountains. Thus, temporal surveys of insect communities and climates at local scales are important for predicting temporal changes in the communities.

    Abstract The prey preference of a predator can impose natural selection on prey phenotypes, including body size. Despite evidence that large body size protects against predation in insects, the determinants of body size variation in Cassidinae leaf beetles are not well understood. We examined the prey preference of the digger wasp Cerceris albofasciata, a specialist predator of adult Cassidinae leaf beetles, and found evidence for natural selection on prey body size. The wasp hunted prey smaller than the size of their nest entrance. However, the wasp preferred larger prey species among those that could be carried into their nest. Thus, the benefits of large prey and the cost associated with nest expansion might determine the prey size preference. As expected from the prey species preference, the wasp preferred small individuals of the largest prey species, Thlaspida biramosa, and large individuals of the smallest prey species, Cassida piperata, resulting in natural selection on body sizes. In intermediate-sized prey species, however, there was no evidence for selection on body size. Natural selection on body size might explain the variation of prey morphologies that increase body size, such as explanate margins, in this group.

    The Indian subcontinent has an origin geologically different from Eurasia, but many terrestrial animal and plant species on it have congeneric or sister species in other parts of Asia, especially in the Southeast. This faunal and floral similarity between India and Southeast Asia is explained by either of the two biogeographic scenarios, ‘into-India’ or ‘out-of-India’. Phylogenies based on complete mitochondrial genomes and five nuclear genes were undertaken for ricefishes (Adrianichthyidae) to examine which of these two biogeographic scenarios fits better. We found that Oryzias setnai , the only adrianichthyid distributed in and endemic to the Western Ghats, a mountain range running parallel to the western coast of the Indian subcontinent, is sister to all other adrianichthyids from eastern India and Southeast–East Asia. Divergence time estimates and ancestral area reconstructions reveal that this western Indian species diverged in the late Mesozoic during the northward drift of the Indian subcontinent. These findings indicate that adrianichthyids dispersed eastward ‘out-of-India’ after the collision of the Indian subcontinent with Eurasia, and subsequently diversified in Southeast–East Asia. A review of geographic distributions of ‘out-of-India’ taxa reveals that they may have largely fuelled or modified the biodiversity of Eurasia.

    The rapid divergence of genital morphology is well studied in the context of sexual selection and speciation; however, little is known about the developmental mechanisms underlying divergence in genitalia. Ground beetles in the subgenus Ohomopterus genus Carabus have species-specific genitalia that show coevolutionary divergence between the sexes. In this study, using X-ray microcomputed tomography, we examined the morphogenesis of male and female genitalia in two closely related Ohomopterus species with divergent genital morphologies. The morphogenetic processes generating the male and female genitalia at the pupal stage were qualitatively similar in the two species. The male aedeagus and internal sac and female bursa copulatrix were partially formed at pupation and developed gradually thereafter. The species-specific genital parts, male copulatory piece, and female vaginal appendix differed in the timing and rate of development. The relatively long copulatory piece of Carabus maiyasanus began to develop earlier, but subsequent rates of growth were similar in the two species. The timing of the formation of the vaginal appendix and initial growth rates were similar, but subsequent rapid growth led to a longer vaginal appendix in C. maiyasanus. Thus, substantial interspecific differences in the size of genital parts were mediated by different underlying developmental mechanisms between the sexes (i.e., a shift in the developmental schedule in males and a change in growth rate in females). These results revealed the spatio-temporal dynamics of species-specific genital structure development, providing a novel platform for evo-devo studies of the diversification of genital morphologies.

    Abstract Ecological character displacement predicts that interspecific resource competition results in greater trait divergence between species in sympatry than in allopatry. However, other processes, such as ecological sorting, result in the same pattern of trait variation. In this study, we characterize character displacement in eight species of snail-feeding Acoptolabrus ground beetles in the Far East. Acoptolabrus exhibit divergent feeding phenotypes, including species with a slender forebody that is able to intrude into large shells and species with stout heads and mandibles for crushing small shells. The pattern of character displacement in feeding phenotypes was confirmed by multivariate analysis of body dimensions. Molecular phylogenetic analysis, divergence time estimation and biogeographical analysis revealed that sympatry and phenotypic divergence occurred repeatedly during the Pleistocene and almost simultaneously within each geographical area. Comparative analysis revealed that the evolution of feeding phenotypes best fitted a selective model with three adaptive optima, corresponding to the three cases of sympatry with a congener. Repeated coincidences of sympatry and adaptive differentiation in feeding phenotypes suggested causal relationships, although the precise order of events was difficult to discriminate. This study provides insight into the spatiotemporal dynamics of interspecific interactions and adaptive phenotypic diversification.

    Sexual traits are subject to evolutionary forces that maximize reproductive benefits and minimize survival costs, both of which can depend on environmental conditions. Latitude explains substantial variation in environmental conditions. However, little is known about the relationship between sexual trait variation and latitude, although body size often correlates with latitude. We examined latitudinal variation in male and female sexual traits in 22 populations of the false blister beetle Oedemera sexualis in the Japanese Archipelago. Males possess massive hind legs that function as a female-grasping apparatus, while females possess slender hind legs that are used to dislodge mounting males. Morphometric analyses revealed that male and female body size (elytron length), length and width of the hind femur and tibia, and allometric slopes of these four hind leg dimensions differed significantly among populations. Of these, three traits showed latitudinal variation, namely, male hind femur was stouter; female hind tibia was slenderer, and female body was smaller at lower latitudes than at higher latitudes. Hind leg sizes and shapes, as measured by principal component analysis of these four hind leg dimensions in each sex, covaried significantly between sexes, suggesting coevolutionary diversification in sexual traits. Covariation between sexes was weaker when variation in these traits with latitude was removed. These results suggest that coevolutionary diversification between male and female sexual traits is mediated by environmental conditions that vary with latitude.

    The diversity of genital morphology among closely related animals with internal fertilization is well known, but the genetic backgrounds are unclear. Here, we show that, in Carabus (Ohomopterus) beetles showing correlated evolution of male and female genital parts, only a few major quantitative trait loci (QTLs) determine differences in genital dimensions between sister species, and sequence divergence is pronounced in the genomic regions containing genital QTLs. The major QTLs for male and female genital dimensions reside in different locations within the same linkage group, implying that coevolution between the sexes is only loosely constrained and can respond to sexually antagonistic selection. The same genomic regions containing the major QTLs show elevated divergence between three pairs of parapatric species with marked differences in genital parts. Our study demonstrates that species diversification can follow coevolution of genitalia between the sexes, even without tight linkage of loci affecting male and female genital dimensions.

    Biogeography, an interdisciplinary field drawing on evolutionary ecology, community ecology, and conservation biology, aims to elucidate the processes shaping species distributions from both ecological and historical perspectives. Since the 1990s, biogeography has been advanced by the growth of phylogeography, with its basis in genetic analysis. New analytical tools, including geographic information systems (GIS), climate simulations, and ecological niche modeling (ENM), have brought further innovations. Combining simulations of past or future climates with ENM has allowed the estimation of past or future species distributions. Furthermore, combined analyses using GIS-related tools can reveal the processes of niche differentiation and speciation, and be used to reconstruct the migration histories of biological communities. In this review, we highlight useful analytical tools and data sources and explore their practical applications in biogeography and related fields. Next, we discuss the prospects of biogeography as a more integrated field, combining various data sources such as ancient DNA and the unprecedented amount of genetic data now available from next-generation sequencers.

    生態的に似た複数の近縁種が共存するには、種間の資源競争あるいは繁殖干渉が緩和される必要がある。オサムシ科オオオサムシ亜属は、成虫期に多食性の捕食者であるが、幼虫期はミミズ専食である。またオスは異種のメスに対しても交尾行動を示す。彼らは分布域の大部分で2-3種が共存しており、同所的に分布する種間では体サイズが異なっている。この種間の体サイズ差は、幼虫期に捕食可能なミミズのサイズに応じた資源分割をもたらし、資源競争を緩和するかもしれない。また成虫期に異種間の交尾行動を機械的に妨げる生殖隔離として、繁殖干渉を緩和するかもしれない。この2つの仮説を、京都に分布するオオオサムシ亜属4種(山間部の大、中、小型の3種、平野部の大型1種)を用いて検証した。まず、4種の幼虫(1-3齢)に様々なサイズのミミズを与えた。その結果、すべての幼虫は、ミミズのサイズに関わらず捕食行動を示した。またミミズのサイズ増加に伴う捕食失敗は、小型種の1齢幼虫期でのみ観察された。したがって、種間の体サイズ差は資源分割に有効ではないと考えられた。次に、4種の成虫で16通りの雌雄ペアを作り、交尾行動(交尾意欲、マウント、交尾器の挿入、精包形成)を観察した。その結果、体サイズ差が大きい異種ペアでは、交尾意欲があっても交尾器が届かず、挿入ができないペアが多かった。すなわち、種間の体サイズ差による交尾前生殖隔離が成立しており、このことが体サイズ差の大きい近縁種の同所的分布を可能にしていると考えられた。一方、体サイズ差が小さい異種ペア(山間部の大、中型種と平野部の大型種のペア)では、大半のペアで交尾器の挿入が行われ、精包形成まで達成するペアも見られた。このことから、体サイズの似た種が同所的に分布しないのは、資源競争ではなく繁殖干渉のためであることが示唆された。

    Preference for certain types of flowers in bee species may be an adaptation for efficient foraging, and they often prefer flowers whose shape fits their mouthparts. However, it is unclear whether such flowers are truly beneficial for them. We address this issue by experimentally measuring foraging efficiency of bumblebees, the volume of sucrose solution consumed over handling time (μL/second), using long-tongued Bombus diversus Smith and short-tongued B. honshuensis Tkalcu that visit Clematis stans Siebold et Zuccarini. The corolla tube length of C. stans decreases during a flowering period, and male flowers are longer than female flowers. Long- and short-tongued bumblebees frequently visited longer and shorter flowers, respectively. Based on these preferences, we hypothesized that bumblebee foraging efficiency is higher when visiting flowers that show a good morphological fit between the proboscis and the corolla tube. Foraging efficiency of bumblebees was estimated using flowers for which nectar quality and quantity were controlled, in an experimental enclosure. We show that 1) the foraging efficiency of B. diversus was enhanced when visiting younger, longer flowers, and that 2) the foraging efficiency of B. honshuensis was higher when visiting shorter female flowers. This suggests that morphological correspondence between insects and flowers is important for insect foraging efficiency. However, in contradiction to our prediction, 3) short-tongued bumblebees B. honshuensis sucked nectar more efficiently when visiting younger, longer flowers, and 4) there was no significant difference in the foraging efficiency of B. diversus between flower sexes. These results suggest that morphological fit between the proboscis and the corolla tube is not a sole determinant of foraging efficiency. Bumblebees may adjust their sucking behavior in response to available rewards, and competition over rewards between bumblebee species might change visitation patterns in the wild. Thus, the determinants of foraging efficiency and visitation frequency for bee pollinators may be more complex than previously thought.

    We investigated long-term changes in the distribution of two pierid butterflies, Artogeia rapae (=Pieris rapae) and A. melete (=P. melete) in Tokyo, using questionnaire survey, literature searching and field observations. From the 1950s to the 1960s, A. rapae was observed at many sites across Tokyo. From the 1970s, observation records of A. melete increased and A. melete became common even in the urban area of Tokyo during the 1980s. From the 1990s, however, observation records of A. melete decreased and those of A. rapae increased again. These changes of distribution of A. rapae and A. melete were evident not only in the urban area, in 23 wards, but also in rural areas.

    The geographic variation in body size of an insect species may reflect not only differential adaptation to local climatic conditions but also evolutionary consequences of interaction with closely related species. Thus, both intra- and interspecific body size variations need to be analyzed to understand evolutionary significance of geographic pattern of body size variation in a group of closely related species. Here, we introduce geographic patterns of intra- and interspecific body size variation in two groups of carabid beetles in Japan, Leptocarabus and Ohomopterus (the subtribe Carabina, Carabidae) and discuss the possible factors leading to the observed patterns. Body size of a species generally decreases with decreasing warmth of the habitat (the converse of the Bergmann's rule). However, coexisting related species at sympatric zones show separation in body size, leading to deviation from overall clinal trend of body size variation within species. Probably, interspecific interaction through reproductive interference at the secondary contacts has played a role in determining the combination of species that could coexist or affected the body size differentiation per se.

    本研究は,交雑に起因する交尾器形態の分化と,それに伴う種分化の過程を検証する.交尾器形態の違いが機械的生殖隔離をもたらすオオオサムシ類について,これまで進められてきた研究をさらに発展させ,種分化過程における交尾器形態とゲノムの分化機構と,形態の遺伝発生学的基盤を明らかにすることを目的とする. (1)種間交雑に伴う形態とゲノムの分化機構の解明:分布を接する近縁種を対象に,行動実験によって交尾器形態の形質置換をもたらした自然淘汰を定量する.集団ゲノミクス解析により,自然淘汰と遺伝子流動の影響下にあるゲノムの分化動態を解明する.これまで,他種と接触し交尾器形態に形質置換が見られる複数の個体群において,より種間差の大きい形態変異が種間交尾のコスト(交尾器の損傷,交尾時間のロス)を低減しうるという自然淘汰を検出した.また,比較ゲノム解析のためのサンプリングを行い,ゲノムシーケンスデータを蓄積した. (2)遺伝発生学的基盤の解明:マイクロCTとin situ hybridizationを用いた形態形成・遺伝子発現解析により,交尾器形態の発生過程と,形態の種間差に関わる遺伝的背景を解明する.これまで,最も巨大化した交尾器を持つドウキョウオサムシの発生過程サンプルを取得し,マイクロCTによる形態の観察と測定を進めている.また,in situ hybridizationの実験系を構築するため,ポジティブコントロールのアクチン遺伝子を使って条件設定を進めつつある.

    To clarify the role of the loss of flight ability in the species diversification process of ground-living beetles in the world, molecular phylogeographic analyses were performed for three groups with flight polymorphisms, Cicindelidae, Carabinae, and Silphinae. These groups were estimated to have diverged in the Jurassic to Cretaceous, and in all of them, basal lineages with deep branching were distributed in the lands of Gondwana origin such as Africa, South America, and Australia, and their species diversity were generally low. Loss of flight ability is observed in most groups of Carabinae, in the basal groups and some of the derived groups in Cicindelidae, and only in the derived groups of Silphinae. The flightlessness was related to low species diversity in the basal lineages of Cicindelidea, whereas it was related to increased species diversity in Carabinae and Silphinae.

    In the bicolored false blister beetles Oedemera sexualis (Coleoptera, Oedemeridae), males possess swollen femora of the hind legs and use their hind legs to control resistant females during their mating attempts. Male hind femora show a latitudinal cline, becoming stouter at lower latitudes. However, some populations on the Amami Islands constitute significant outliers from the cline with exceptionally narrow male hind femora. We conducted mating experiments and detected different selection pressures on male morphologies among different populations; males with larger hind legs had higher mating success in the Naruto and Yonaguni populations, whereas males with slender hind legs were more successful in the Amami population. In the phylogenetic analysis, it has been revealed that all individuals including Amami population possessing thin femurs had directly derived from the lineages of thick femurs.

    This research investigated ecosystem valuation around Mt. Rokko, which is located near Kobe, a major city in Japan. Special attention was paid to how differences in lifestyle and experiences of valuators influence willingness to pay. It was found that certain experiences had a significant effect on valuation of ecosystem services. From psychological analysis, it was also found that psychological measure offered the different results from welfare measure. These findings suggest the importance of considering the diversity of valuators, and it also warns the extinction of experience with nature under on going urbanization for urban ecosystem conservation. This research concludes that measurement approach, recognition process, urbanization and lifestyle change are important in ecosystem service valuation.

    We analysed reproductive isolation, reproductive interference, and character displacement in Isodon umrosus with the short corolla and I. effusus with the long corolla. Artificial pollination between two species revealed that seed production and seed germination were very low, suggesting that hybridization between these two species is maladaptive. Seed production of wild plants in sympatric population was lower than that in allopatric population, indicating that the reproductive interference between the species occur in the field. In a sympatric site (Kanoto-iwa), flowering phenology differed between the species, which may play a role in avoiding their reproductive interference. The molecular phylogenetic analysis based on nuclear DNA sequences supported the previous taxonomic treatment of the genus at the species level.

    In order to clarify the evolutionary origin of primitively social behavior in Pompilidae, female nesting and social behaviors of Machaerothrix tsushimensis were investigated. The results of the investigations are that two females each may make and provision their own cell(s) in a composite nest (communal) and that some of the females shift their own nests with time. Moreover, genetic differentiation between individuals at two nesting sites (about 100 m apart from each other) was analyzed. The results of the analyses are that 1) females are genetically much differentiated between the nesting sites; and 2) males are not so much differentiated between them. Although males may facilitate genetic interchange between the sites, genetic similarity of individuals at a site seems to be great. There is a possibility that the formation of a kin group associated with settled life or low migratory activity concerns the evolution and maintenance of primitive sociality in this species.

    This study aimed to reveal sexual selection for exaggerated genital morphology and genes related to species-specific genital morphology in the ground beetle group Ohomopterus, which exhibited a marked interspecific divergence in shape and size in male and female genitalia. In an experiment to study selection on genital size using within-species variations, matching in genital sizes between the sexes was favored for sperm competition, and it was suggested that sexual conflict or reproductive interference with another species needs to be considered for an explanation of exaggeration of genital morphology. In a comparison of transcriptomes between two sister species with marked differences in genital morphology, some genes with differential expressions between the species were found, but these were unlikely to be the genes affecting species-specific genital morphology.

    To understand how the land snail fauna is related with the divergence of morphology related to snail feeding (macrocephalism vs. stenocephalism) in the subtribe Carabina, we conducted field studies in China, Korea, Armenia, and Morocco. In the inland region of China, especially, diverse snail-feeding Carabina species and land snails occur. Macrocephalic Carabina species occur in habitats harboring small-sized bradybaenid snails abundantly. In habitats where both macro- and stenocephalic Carabina species occur, the shell morphology of bradybaenid snails was markedly diversified, suggesting an adaptive radiation due to strong predation pressure from snail-feeding predators.

    In order to elucidate the evolutionary origin of primitively social behavior in Pompilidae, male mating behavior of Machaerothrix tsushimensis and relatedness of its individuals at the same nesting site were investigated. As a result, it was found that the males rested for a long time(400 minutes, for example) near the entrances of the nests, attempting to copulate with the females and that multiple females nesting at the same site had the same father. These suggest that the copulation oligopoly by a few males occurs in this species. As a result of measuring several morphological characters of Macromeris violacea, positive allometry was found between the body length(length of forewing marginal cell) and the leg(femur) thickness only in the male, and thus the thick male femur is presumed to be a character that enables copulation monopoly by one or a few males on the nest.

    We aimed to test whether ecological speciation could result from differentiation of body size between populations adapted to different altitudinal conditions, focusing on the body size variation among Carabus (Ohomopterus) tosanus populations at different altitudes. Molecular phylogenetic analyses showed that C. tosanus was a monophyletic group diverged within Shikoku and that there were only small genetic divergence among populations at different altitudes, despite that body size was clearly smaller at elevations of about 1000 m or higher. Field study indicated that the smaller body sizes at higher altitudes was related to adaptive responses to temperature and food (earthworms) conditions which were limited at higher altitudes. Laboratory experiments showed that the differences in body length between populations from different altitudes were largely determined by genetic differences with a small effect of plastic responses to temperature. The analysis of heritability revealed that the difference between populations was attributable to maternal inheritance (probably due to genes on X chromosome). Mating experiments showed that the body length difference caused a mechanical reproductive isolation, suggesting that the body size differentiation can result in speciation.

    雌雄交尾器に見られる錠と鍵的対応の進化過程を解明するため,甲虫目オサムシ科の各種を用いて,以下の研究を行った. 1)交尾器形態と交尾行動の相関した進化 オオオサムシ亜属に特徴的な交尾片は,精子競争における精包の掻き出しに機能している可能性がある.この仮説から予測される交尾片サイズと精包サイズの相関した進化を,22分類群の種間比較解析により検討した.系統的な制約をコントロールするため,核遺伝子5遺伝子座を元にした最尤系統樹を用いて,独立な対比に基づく解析を行った.結果,1)交尾片と精包のサイズは体サイズと比較してそれぞれ3倍および等倍率で進化している;2)交尾片と精包のサイズは正に相関する;3)交尾片と交尾時間は負に相関する,ことが明らかとなった.(論文投稿中) 2)精子競争における交尾器の機能 オサムシ類の精子競争における精包の掻き出し仮説を検証するため,多回交尾下での精包分布と父性の変化を調べた。マイクロサテライト遺伝子を用いた父性解析の結果,80%の確率で精包の掻き出しが起こり,それは掻き出した雄の父性の獲得に寄与していることが明らかとなった(論文投稿中). 3)二型的精子束の進化 精子競争によって生じる性淘汰は,交尾器形態以外にも働き,顕著な形質進化を引き起こし得る.オオオサムシ類で発見された二型的精子束が精子競争による性淘汰の影響を受けているかを明らかにするため,種間比較解析により,交尾器形態や交尾行動との相関した進化の検出を試みた.結果,大小の精子束はそれぞれ著しい多様化を示し,大きな精子束のサイズは交尾片長,交尾後保護時間と正に相関した.これは,著しい精包掻き出しが生じる状況で,大きな精子束が有利になるような性淘汰が働いたことを示唆する(論文準備中).
