Masayuki Maki, Plant Species Biology, 34, 10.1111/1442-1984.12239, 0913-557X, © 2019 The Society for the Study of Species Biology A recent phylogenetic study based only on chloroplast DNA (cpDNA) variation revealed that populations of an Isodon species are frequently embedded paraphyletically among other Isodon species. This phylogenetic discrepancy between species taxonomy and molecular phylogeny was considered to have resulted from chloroplast DNA captures and/or incomplete lineage sorting. To elucidate which of these factors was mainly responsible for the observed phylogenetic pattern, we performed phylogenetic analyses of multiple populations of Isodon species in Japan using cpDNA variation, three single-copy nuclear genes, and double-digest restriction-site-associated DNA sequencing (ddRAD-seq). Although a species often shared chlorotypes with other species, our phylogenetical analyses based on variation in the three single-copy nuclear genes and the ddRAD-seq data showed that most populations belonging to the same species were monophyletic at the species level, suggesting that chloroplast capture may have frequently occurred between Isodon species. Some populations of an intraspecific taxon were embedded paraphyletically within the species, regardless of the large amount of phylogenetic information in nuclear DNA; this incongruity may have resulted from incomplete lineage sorting.

Does Urbanization Promote Floral Diversification? Implications from Changes in Herkogamy with Pollinator Availability in an Urban-Rural Area

Ikumi Dohzono, AMERICAN NATURALIST, UNIV CHICAGO PRESS, 184, 2, 研究論文（学術雑誌）, 10.1086/676855, 0003-0147, Although land-use changes such as urbanization have dramatically altered plant-pollinator interactions, little is known about their effects on pollen limitation and floral traits. In this study, we examined pollinator visit frequency, reproductive success, and floral trait measurements in 12 populations of the annual andromonoecious Commelina communis in an urban-rural area Pollinator and mate availability decreased significantly with developed land area around the study site. Most urbanized populations suffered from significant pollinator-limited male and/or female reproductive success. High fruit set in urbanized populations may suggest the presence of high reproductive assurance by selfing. The stigma height and degree of herkogamy significantly decreased with increased pollinator limitation. Petal length, anther height, and/or the pollen : ovule ratio tended to be low in pollinator- and mate-limited urban populations. One urban population with high pollinator availability had flowers with higher herkogamy and stigma height compared to rural populations. These results suggest that urbanization may provide diverse selective forces that could affect the phenotypic variation in floral traits.

Kazuo Suzuki, Plant Species Biology, Wiley-Blackwell, 25, 3, 10.1111/j.1442-1984.2010.00290.x, 0913-557X, Phylogenetic relationships between 14 taxa of Isodon (Lamiaceae) occurring in Japan and South Korea were examined using sequence variations in 11 chloroplast DNA regions. The phylogenetic tree based on the sequence of 6478 bp did not reflect a previous taxonomic treatment of the genus at the section level: the three main clades contained species in different sections. Furthermore, individuals from different populations in the same species were rarely monophyletic in the tree. In addition, individuals forming monophyletic groups did not show geographical proximity. Lineage sorting of chloroplast DNA variations following rapid divergence of the taxa is likely to have caused complex phylogeny of the taxa, which was reconstructed in the present study. Another possible explanation could be ancient introgressions and resultant chloroplast capture.

Morphological and genetic differentiation in Isodon umbrosus by altitudinal variation in bumblebee pollinator assemblages
2010年04月, Ikumi Dohzono
Kazuo Suzuki, Plant Species Biology, WILEY-BLACKWELL PUBLISHING, INC, 25, 1, 研究論文（学術雑誌）, 10.1111/j.1442-1984.2010.00268.x, 0913-557X, The corolla tube length of the bumblebee-pollinated plant Isodon umbrosus shows conspicuous geographical variation, corresponding with the proboscis length of its bumblebee pollinators across its distributional range. We hypothesized that altitudinal variation in the pollinator assemblage is a principal factor mediating morphological and genetic differentiation among I. umbrosus populations. We examined determinants of the morphological and genetic differentiation of Isodon umbrosus by analyzing floral morphology and allozyme variation across the distributional range. A reanalysis of previous data confirmed that altitude was a good indicator of pollinator assemblages. Corolla tube length was highly variable among the 15 study populations, and genetic differentiation among the populations (G(ST) = 0.360) was also highly significant. The differentiation in corolla tube length was explained by altitudinal difference, a proxy of the difference in pollinator assemblages. Genetic differentiation among populations also tended to be affected by the same factor, but statistical support was weak. To better understand the mechanisms responsible for morphological and genetic differentiation in I. umbrosus, we need to investigate altitudinally different populations over a narrower geographical scale.

Impacts of alien bees on native plant-pollinator relationships: A review with special emphasis on plant reproduction

Jun Yokoyama, Applied Entomology and Zoology, JAPAN SOC APPL ENTOMOL ZOOL, 45, 1, 研究論文（学術雑誌）, 10.1303/aez.2010.37, 0003-6862, Alien pollinators can disrupt mutualistic plant-animal interactions. Here we review studies on alien bee pollinators, demonstrating the ways in which invasive honeybees and bumblebees affect native plant seed production. Impacts of alien pollinators vary among pollination systems and among components of pollination success (visitation frequency, pollen transfer per visit, and pollen limitation). Reproduction of native bird-pollinated plants is little impacted by alien honeybees, because birds can pollinate even when honeybees visit target flowers. In bee-pollinated native plants, alien honeybee impacts on reproduction may be pervasive, but are not clearly defined in many cases; this lack of clarity arises because very few control sites without invasive bees are available, making comparative evaluation impossible. In bumblebee-pollinated plants, alien bumblebee effects are strong because native and invasive bee species are closely related congeners (of the genus Bombus) with similar pollinator mechanisms; alien bumblebees compete strongly with natives or replace them. In general, morphological, ecological, and behavioral similarities between native and alien pollinators are important for predicting their competitive interaction intensities and their effects on plant reproduction. The impacts of alien bees include (1) decreased pollen transfer per visit because of the loose morphological correspondence between flowers and alien bees, (2) increased competition for floral resources and exclusion of native pollinators because native and alien bees have similar ecological requirements, (3) changes in native pollinator visitation frequency and pollination efficiency caused by particular alien pollinator behavioral traits (such as stealing nectar or collecting previously-deposited pollen from stigmas). For a quantitative evaluation of invasion impacts, it is important to determine whether native plants suffer pollen limitation. To demonstrate pollen limitation, comparative studies with controls (that lack alien pollinators) are required. This approach is essential for discerning possible mechanisms responsible for observed patterns.

Complex zygomorphic flowers tend to be oriented horizontally. It is hypothesized that a horizontal flower orientation ensures effective pollen transfer by facilitating pollinator recognition (the recognition-facilitation hypothesis) and/or pollinator landing (the landing-control hypothesis). To examine these two hypotheses, we altered the angle of Commelina communis flowers and examined the efficiency of pollen transfer, as well as the behavior of their visitors. We exposed unmanipulated (horizontal-), upward-, and downward-facing flowers to syrphid flies (mostly Episyrphus balteatus), which are natural visitors to C. communis. The frequency of pollinator approaches and landings, as well as the amount of pollen deposited by E. balteatus, decreased for the downward-facing flowers, supporting both hypotheses. The upward-facing flowers received the same numbers of approaches and landings as the unmanipulated flowers, but experienced more illegitimate landings. In addition, the visitors failed to touch the stigmas or anthers on the upward-facing flowers, leading to reduced pollen export and receipt, and supporting the landing-control hypothesis. Collectively, our data suggested that the horizontal orientation of zygomorphic flowers enhances pollen transfer by both facilitating pollinator recognition and controlling pollinator landing position. These findings suggest that zygomorphic flowers which deviate from a horizontal orientation may have lower fitness because of decreased pollen transfer.

Koichi Goka, ECOLOGY, ECOLOGICAL SOC AMER, 89, 11, 研究論文（学術雑誌）, 10.1890/07-1491.1, 0012-9658, The invasive alien bumble bee Bombus terrestris may hinder the reproduction of native plants that have established specialized pollination systems with native bumble bees. To test this hypothesis, we examined the visitation frequency and behavior of native and alien bumble bee species and resultant seed production in Corydalis ambigua, a native plant in Hokkaido, Japan. This species is self-incompatible: the flower has a spur and requires visitation by bumble bees for effective seed production. We compared visitation frequency as well as fruit and seed set after cross- and open pollination at five sites of C. ambigua. Four of these sites occurred near a residential district and included naturalized populations of B. terrestris, and the fifth site was located in a forested habitat with no B. terrestris. The native species B. ardens and B. hypocrita and the alien B. terrestris frequently visited C. ambigua. Bombus ardens legitimately consumed nectar, whereas B. hypocrita and B. terrestris rob nectar by perforating spurs. The legitimate pollinator B. ardens produced fruits and seeds more efficiently than the nectar robbers. At three sites, the proportion of robbed flowers per inflorescence gradually increased through the flowering period, which may be caused by the intrusion of alien B. terrestris into the native plant-pollinator interactions. At these sites, C. ambigua suffered from pollen limitation, as seed production from open pollination was lower than from cross- pollination, despite the fact that the total abundance of three bumble bees was higher than in the other two sites. Legitimate B. ardens visited fewer flowers within inflorescences with more robbed flowers, suggesting that nectar robbing may reduce the frequency of visitations by B. ardens within inflorescences, and resulting in decreased fruit set. Furthermore, reduced seed set implies a reduction in the pollination quality by B. ardens, probably due to decreases in visiting time per flower. Thus, introduction of alien B. terrestris may alter the native plant-pollinator mutualism: C. ambigua could establish a novel pollination relationship with B. terrestris because of its nonzero pollination efficiency, similar to the native robber B. hypocrita.

This species is protandrous, partially self-incompatible at postzygotic stages, and requires outcrossing via pollinator visitation for effective seed production. The effective pollinators were two bumblebee species: males of Bombus ardens at Miyama, and workers of Bombus honshuensis at Agematsu. The flowers possess two staminodes ornamented with whitish hairs, which do not reflect UV light, on the filaments. Nectar was secreted continuously during the flowering period, and nectar production rate differed between the sites. Visitation by B. ardens males was more frequent and varied among and within days, whereas that by B. honshuensis workers was less frequent and constant throughout the observation period. A single visit by a B. ardens male was more effective for seed production than visitation by a B. honshuensis worker, resulting in pollen limitation in the latter case. Differences in resource requirements between the two pollinators, representing different castes, might affect their behavior, resulting in B. ardens males contributing to more effective seed production.

Evolution of pollinator generalization in bumblebee-pollinated plants

To outline recent advances on this topic, we review studies of five bumblebee-pollinated plants in Japan. These plant species are pollinated by one to three bumblebee species differing in proboscis length: Bombus consobrinus, Bombus diversus and Bombus honshuensis. These pollination systems allow us to compare the reproductive strategies of plants pollinated by single and multiple bumblebee species. First, we address the effects of morphological correspondence between flowers and pollinators on the reproductive success of plants. In plants with narrow tubular flowers, Isodon umbrosus and Clematis stans, pollination effectiveness depended on the morphological correspondence between floral tube length and pollinator mouthparts. These flowers are subject to varied directions and intensities of selection by multiple bumblebee species, resulting in the maintenance of large variation in floral morphology within and between populations, and even within individuals. In contrast, pollination effectiveness in plants having flowers with a wide entrance, Melampyrum roseum and Hosta sieboldiana, did not differ among bumblebee species because of good correspondence between floral morphology and bumblebee body size, resulting in small morphological variations among flowers. Thus, generalized pollination systems with multiple pollinator species favor floral traits that enable the use of various pollinators. Second, we address the quantity and quality of the pollination service in bumblebee-pollinated plants. Isodon umbrosus, with its generalized pollination system, suffered from pollen limitation because of low pollination quality. In contrast, Isodon effusus, which has a specialized pollination system, suffered from pollen limitation because of low pollination quantity. Isodon umbrosus produced large numbers of short tubular flowers to improve pollination quantity, whereas I. effusus produced small numbers of long tubular flowers to improve pollination quality, resulting in a clear trade-off between the size and number of flowers within plants. In M. roseum, which has a generalized pollination system, three bumblebee species achieved sufficient pollination, but seed production was limited by an increased rate of self-pollination. This is because this species invests more resources in cross-pollinated seeds by selective abortion of selfed seeds. Our results demonstrate that the strategy of generalized plants is to improve pollination quantity, whereas the strategy of specialized plants is to improve pollination quality.

Temporal changes in calyx tube length of Clematis stans (Ranunculaceae): A strategy for pollination by two bumble bee species with different proboscis lengths

J Murata, American Journal of Botany, BOTANICAL SOC AMER INC, 91, 12, 研究論文（学術雑誌）, 10.3732/ajb.91.12.2051, 0002-9122, We examined the adaptive significance of a temporal decrease in the calyx tube length of Clematis stans, a dioecious species pollinated by Bombus diversus (long proboscis) and B. honshuensis (short proboscis). We compared visitation frequency, pollen removal, pollen deposition, and fruit set after a single visit among three flower stages, differentiated by calyx tube length. Bombus diversus frequently visited and removed significantly more pollen from long flowers. Bombus honshuensis visited and tended to remove more pollen from short flowers. Both pollinators deposited more pollen in short flowers, resulting in higher fruit set. These results indicate that size correspondence between the proboscis and the calyx tube enhances visitation frequency and pollen removal, but not pollen deposition. Because a single visit does not fertilize all Ovules of a flower, multiple visits by two humble bee species may increase seed production and genetic diversity of offspring. By temporally changing calyx tube length, C. stans can use two humble bee pollinators and maintain specialized relationships with each. This strategy may be adaptive when the pollinator fauna fluctuates, and is economical because it eliminates costs required to produce different types of flowers. This constitutes a novel pattern of temporal specialization in flower-pollinator relationships.

This is a topic of recent interest in pollination biology, but quantitative evidence is limited. We have determined whether flowers of Hosta sieboldiana are morphologically specialized for one of the three pollinating bumblebee species, Bombus consobrinus, B. diversus and B. honshuensis, which have significantly different proboscis lengths from each other. We measured the amount of pollen removed from the anthers and the amount of pollen deposited on the stigma at each single visit to the flowers of H. sieboldiana, as measures of pollination effectiveness. We found that the pollination effectiveness did not differ among the three bumblebee species. We also determined which part of a flower or pollinator is related to the pollination effectiveness of each of the three bumblebee species. A floral structure consisting of a protruding pistil and stamens and a tapered broad-tube part may lead to similar pollination effectiveness among the bumblebee species. Flowers of H. sieboldiana are not morphologically specialized for any one of the three bumblebee species.

Bumblebee-pollination and temporal change of the calyx tube length in Clematis stans (Ranunculaceae)

Both male and female flowers produce nectar from the base of the calyx tube during a flowering period of 3 or 4 days, and are pollinated by two bumblebee species, Bombus diversus and B. honshuensis, with different proboscis lengths. When the flowers open, four sepals constructing a calyx tube separate at the top and their respective tips gradually curl up, so that a tubular part shortens. Observations at two field sites showed that B. diversus (with a longer proboscis) most often visits the flowers with a longer calyx tube, and B. honshuensis (with a shorter proboscis) the flowers with a shorter calyx tube, i.e., later in the flowering period. By changing the calyx tube length, the flowers of C. stans accept the two. bumblebee species with different proboscis length as pollinators and thus increase the chance of pollination for each flower. It was also found that the two bumblebee species prefer the male flowers to the female flowers, although the female flowers secrete more nectar as a reward than male flowers. This is likely because they visit the male flowers to collect pollen grains in addition to nectar.

This species can be used to explore the impact of an alien bumblebee on plant reproduction. Genetic diversity and other population genetic parameters were estimated in two populations with and without the alien bumblebee. The number of alleles per locus ranged from 4 to 20, and observed heterozygosities ranged from 0.355 to 0.969. These markers can be applied to study mating systems and population genetics in C.ambigua.
