“…This evolutionary pattern and lack of phylogenetic signal for most traits suggest forces that act on an ecological time scale, rather than changes associated with deep phylogenetic relationships (Gómez et al, 2016). Fritillaries are found in a variety of climatic regions and in different habitats, including coasts, riparian zones, meadows, woodland, steppe, deserts, mountain screes, and alpine zones (Tomović et al, 2007;Tekñen and Aytaç, 2008;Zox and Gold, 2008;Hill, 2011Hill, , 2016Tekñen and Aytaç, 2011;Rix and Strange, 2014;Zych et al, 2014;Gao et al, 2019). Consequently, some aspects of the floral display may have arisen by selection pressure exerted by abiotic factors related to the habitat type, such as temperature, altitudinal gradients, or water stress (Zhao and Wang, 2015;Landis et al, 2018;Gao et al, 2019).…”

In addition, some of the observed variability should be attributed to the potential for natural hybridisation ( Naruhashi et al, 2006 ; Kawano et al, 2008 ; Hill, 2011 ).…”

Pollinators are often perceived as a primary selective agent influencing flower traits such as colour, size, and nectar properties. The genus Fritillaria L. (Liliaceae), comprising approximately 150 species, is described as generally insect pollinated. However, there are at least three exceptions: two hummingbird-pollinated North American species and one passerine-pollinated Asian species. Despite this variation in pollination, little is known about flower traits that may accompany this shift in fritillaries. In this study, we aimed to assess the attractiveness of the floral traits for (new) pollinators and track the evolution of flowers traits in the context of a shift in the principal pollinator. Therefore, we studied 14 flower traits related to the pollination in 60 Fritillaria species and traced the evolutionary trajectory of these traits. We used a phylogenetic tree of the genus, based on five DNA markers (matK, rpl16, and rbcL, 18S, and ITS) to reconstruct the ancestral state of studied flower traits. The results show that in bird-pollinated species several new traits evolved. For example, flower colouration, nectar sugar, and amino acid concentration and composition fulfil the criteria of ornithophilous flowers, although flower traits do not exclude insect pollinators in bird-pollinated fritillaries. Interestingly, we recorded potential reversals from bird to insect pollination. Our analysis, showing a broad study of flower traits among closely related species in the context of pollinator shift, serves as a starting point for future work exploring the genetic and physiological mechanisms controlling flower traits in the genus Fritillaria.

“…Fritillaria is a genus of spring-owering perennials in the family Liliaceae, which has 130-140 species worldwide and nine species in Japan (Hill 2011). The genus is highly diverse in oral characteristics, including the morphology of the nectary and the compositions of the oral nectar (Roguz et al 2018).…”

Volatile compounds in nectar have various functions, but we still know little about the distribution and functions of scented floral nectar. Here, we report functions of scented nectar in Fritillaria camtschatcensis. In Japan, F. camtschatcensis comprises two varieties, var. keisukei (hereafter, alpine type) and var. camtschatcensis (hereafter, lowland type), both of which secrete a large amount of scented nectar and attract flies as pollinators. We investigated sugar concentration of the nectar using high-performance liquid chromatography (HPLC) and studied the volatile chemical composition of the nectar using gas chromatography-mass spectrometry (GC-MS). We then conducted a bioassay using a synthetic mixture of components of the nectar scent of the lowland type to test if the nectar scent contributes to pollinator attraction. The HPLC analysis showed that substantial amounts of glucose and fructose occur in the nectar of the alpine type. The nectar of the lowland type also contained glucose, albeit at low concentration. The volatile compounds in the nectars were substantially different between the two types: the volatiles of the lowland type consisted of four aliphatic acids, whereas acetophenone was the main compound in the alpine type. The bioassay revealed that the nectar scent of the lowland type is sufficient to attract flies, including the pollinator species. This study showed that the nectar of F. camtschatcensis functions as both a reward and attractant for the pollinators, and indicates that flower nectar is much more diverse in terms of chemical composition and function than commonly thought.

“…Members of the Eurasian clade form part of the relic flora of Japan (Hill, 2011) with four species found in the Sohayaki Region and their nearest relatives in the steppes of central Asia (Rønsted et al, 2005). The Holocene climate oscillations promoted repeat cycles of land bridge formation, isolation and range changes throughout the archipelago and this probably gave rise to peripatric speciation of the group.…”
