Large clades of angiosperms are often characterized by diverse interactions with pollinators, but how these pollination systems structured phylogenetically and biogeographically is still uncertain for most families. Apocynaceae a clade >5300 species worldwide distribution. A database representing >10 % in the family was used to explore diversity pollinators evolutionary shifts across major regions. The compiled from published unpublished reports. Plants were categorized into broad then...
Ametrodiplosis Rübsaamen (Diptera: Cecidomyiidae: Clinodiplosini) is a mostly Holarctic gall midge genus whose species are associated with wide range of seed plant families, either as gall-inducers or inquilines. In this study, we describe three from Japan: A. adetos n. sp. feeding in the flowers Tylophora aristolochioides Miq. (Apocynaceae); aeroradicis inducing aerial root galls on Trachelospermum asiaticum (Sieb. et Zucc.) Nakai and T. gracilipes var. liukiuense stellariae forming leaf...
Pollination by fungus gnats (Mycetophilidae and Sciaridae) is uncommon, but nevertheless known to occur in 20 genera among eight angiosperm families. Because many gnat-pollinated plants possess a dark red floral display, we hypothesized that gnat pollination more widespread with similar display than currently known. We thus studied the biology of flowers pigmentation five families, focusing particularly on having small, flat, actinomorphic exposed nectaries short stamens, because these...
A major goal in the study of mutualism is to understand how co-operation maintained when may potentially turn into parasitism. Although certain mechanisms facilitate persistence mutualism, parasitic species have repeatedly evolved from mutualistic ancestors. However, documented examples reversals are still rare. Leafflowers (Phyllantheae; Phyllanthaceae) include approximately 500 that engage obligate with leafflower moths (Epicephala; Gracillariidae), which actively pollinate flowers, and...
Some flowering plants signal the abundance of their rewards by changing flower colour, scent or other floral traits as are depleted. These trait changes can be regarded honest signals reward states for pollinators. Previous studies have hypothesized that these used to maintain plant-level attractiveness pollinators, but evolutionary conditions leading development not been well investigated from a theoretical basis. We examined evolution in flowers applying model included pollinator response...
Most plants of the family Apiaceae produce large, white umbrella-like inflorescences composed many small open flowers that secrete nectar and pollen (Knuth, 1908). This system allows nearly any type insect to access floral resources gives rise family's reputation for generalist pollination (Bell, 1971; Olesen et al., 2007; Ollerton 2007). Indeed, two members are listed among top 10 in al. (2007), as they attract more than 100 species. Insects visit apiaceous include diverse taxa including...
Summary The genus Vincetoxicum Wolf is one of the most species‐rich genera in Apocynaceae and has diversified Japan. magnificum (Nakai) Kitag. a perennial herb endemic to Most Japanese species flower summer autumn, whereas V. flowers spring. Here we provide images their natural habitats colour painting, detailed illustrations, photos, full description .
PREMISE OF THE STUDY: The genus Hoya (Apocynaceae; Asclepiadoideae) is characterized by a set of complex floral characters unique among the asclepiads, but their role in pollination poorly understood. Here, we report new mechanism asclepiad wax plant carnosa: pollinaria are transferred on legs medium or large settling moths. METHODS: Floral visitors and behavior were observed Amami‐Oshima Island during 2013–2015, efficacy different pollinators was determined counting pollinarium loads flower...
Abstract Pandanus is a morphologically unique plant group of the Paleotropical flora, with approximately 450 known species occupying diverse habitats. Because male inflorescences this genus are pendent and nectarless, they commonly assumed to be wind-pollinated; however, their floral scent coupled observation that female mature while still covered by bracts suggest possibility an alternative pollination mechanism. We studied system odorifer in subtropical Japan. A peroxidase assay was...
Orchidaceae is the most species-rich plant family, with renowned floral diversity. Floral diversity among orchids attributed to of pollination systems, which a product specialization within orchid species different animal pollinators (Micheneau et al., 2009; Schiestl & Johnson, 2013). However, biology remains unknown in over 90% (Ackerman 2023), limiting our understanding full repertoire adaptation Orchidaceae. Dipteran insects are important pollinators, often attracted flowers by unique...

In the montane flora of Taiwan, Anaphalis nepalensis is most widely present species (Compositae), yet its taxonomic status uncertain. study, we employed both morphological and molecular data to demonstrate that A. misidentified does not occur in Taiwan. contrast, name has been misapplied Taiwan previously described endemic species, nagasawae , which can be further divided into two varieties based on number heads inflorescence: var. one or heads, while niitakayamensis three five heads....
Summary We illustrate Metrosideros boninensis (Hayata ex Koidz.) Tuyama endemic to the Chichijima Island group of Ogasawara (Bonin) Islands with a detailed description and photographs its natural habitat. Its pollination biology is discussed in relation floral traits pollinators.
Vincetoxicum Wolf is the third largest genus in Asclepiadoideae, and 23 species are distributed Japan. We discovered that an erect herb species, eastern part of Honshu island, was invalidly named magnificum (Nakai) Kitag. based on Cynanchum Nakai, nomen nudum. Therefore, we presently name this nakaianum K.Mochizuki & Ohi-Toma, give a detailed description study. Additionally, provide photographs demonstrate its ecology diagnostic characteristics.
Abstract Volatile compounds in floral nectar may affect plant–pollinator relationships; however, the understanding of distribution and functions scented is still relatively limited. In this study, we examined volatile constituents black lily Fritillaria camschatcensis their potential to attract flower‐visiting flies. Japan, F. comprises two varieties, var. (lowland) keisukei (alpine). The flowers both varieties secrete large amounts that fed on by visiting We investigated sugar concentration...
Abstract The mating behaviour of a quasi‐gregarious egg parasitoid Telenomus triptus N ixon ( H ymenoptera: P latygastridae), which exploits masses stink bug Piezodorus hybneri eteroptera: entatomidae), is examined in the laboratory. In this wasp, male adults that emerge earlier stay at natal mass and mate with subsequently emerging females. present study, adult encounters emergence another always waits for it to egress, then mounts newly male. To examine why males T. show same‐sex sexual...
Abstract Volatile compounds in nectar have various functions, but we still know little about the distribution and functions of scented floral nectar. Here, report Fritillaria camtschatcensis . In Japan, F. comprises two varieties, var. keisukei (hereafter, alpine type) lowland type), both which secrete a large amount attract flies as pollinators. We investigated sugar concentration using high-performance liquid chromatography (HPLC) studied volatile chemical composition gas...
Abstract Background and Aims Dipteran insects are known pollinators of many angiosperms, but knowledge on how flies affect floral evolution is relatively scarce. Some plants pollinated by fungus gnats share a unique set characters (dark red display, flat shape short stamens), which differs from any pollination syndromes. We tested whether this syndrome associated with gnats, using the genus Euonymus as model. Methods The pollinator colour, morphology scent profile were investigated for ten...
True flies (Diptera) are a hyper-diverse group of insects which considerably under-studied compared to many other organisms.
