“…This could explain the low fruit set observed in our populations and reported in other studies (e.g. Kawano et al 1986;Eriksson and Ehrle´n 1992), although also local abiotic factors (light, humidity) may influence seed set (Kawano et al 1968;Ietswaart and Schoorl 1985). Despite the species' apparent low recruitment rate, genetic diversity within young and old populations was high.…”

Maianthemum bifolium Schmidt (May Lily) is a woodland species with low colonisation ability and high demands for seedling establishment conditions. To study the colonisation process, we analysed the clonal organisation and population structure of Maianthemum bifolium populations in a number of forest fragments using AFLP. A total of 129 genets were identified. Most (41/53) patches of M. bifolium in recent (less than 80 years old) and old (at least 175 years of age) parts of the woodlands contained single genets. Only one of the 12 patches with multiple genotypes showed intermingled growth. Besides seed dispersal also dispersal of vegetative material contributed to colonisation since five genotypes were found in more than one patch, with patches up to 51 m apart. Population differentiation between populations in different forests was significant (F ST = 0.10) and indicated low gene flow. This level of differentiation was already found between populations in different parts of the same forest, just over 200 m apart. In fact, only two adjacent populations were not significantly differentiated, one population located in old forest whereas the other was established next to it on a former pasture re-forested after 1916. Limited gene flow is also consistent with the decrease of genetic similarities with physical distance, which relationship is highly significant but only for distances up to 400 m.

“…Indeed, previous studies showed that M. stellatum Link and M. racemosum Link (belonging to the former Smilacina) in North America are pollinated predominantly by hoverflies (Syrphidae), but also visited by either bees (Apidae and Ha lic tidae) or bumblebees (Bombus spp., Apidae) and some butter flies (Lepidoptera) (Piper 1989). Moreover, hoverflies (Syr phidae) and bumblebees (Bombus spp., Apidae) were recog nized as pollinators in the European population of M. bifolium (belongs to Maianthemum s.s.), whereas other dipteran visitors (Anthomyidae and Asilidae) do not play a sig ni ficant role in pollination (Ietswaart et al 1985). Along with sexual reproduction, vegetative propagation occurs within the Maianthemum.…”

Maianthemum F.H. Wigg. is a genus of perennial plants inhabiting temperate and subtropical regions of Eurasia and North America. Maianthemum sensu stricto includes just a few species that have a wide geographic distribution, are morphologically close, and possess open flowers adapted for a wide range of flower visitors. The present study is aimed at investigating the pollination biology of Maianthemum s.s. A comparison of the pollination biology of these species growing in the same area allows us to clarify ecological differences between the species. Investigation of the pollination biology of the same species in different parts of its range allows for the specification of variation in range of pollinators due to the environmental conditions. We studied pollination of M. bifolium in two far-apart locations (Moscow Region and Primorye Territory); also, in parallel, we studied three species M. bifolium, M. dilatatum, and M. intermedium in the same location in Primorye Territory. Proterandry is typical of all Maianthemum ssp. populations studied here. The studied species have a wide range of flower visitors. All of them can contribute to pollination, but the most stable and effective pollinators of Maianthemum s.s. are bees (Anthophila) and hoverflies (Syrphidae). Geographical position of population is the most important factor defining the range of pollinators of Maianthemum bifolium. The range of pollinators is weakly specific to the three species of Maianthemum s.s.
