“…For this study, three populations (Iso-Salmijärvi, Kanavuori, and Vaarunvuori) were selected from the periphery of the distribution area of L. viscaria in Finland to have approximately the same climatic and other environmental conditions, but with as much difference in the population sizes and genetic variability as possible ( Table 1). There is evidence for partial self-incompatibility in some populations (Wilson et al, 1995), but the studied populations are self-compatible ( Table 1). There is evidence for partial self-incompatibility in some populations (Wilson et al, 1995), but the studied populations are self-compatible ( Table 1).…”

“…Because L. viscaria is sensitive to competition (Wilson et al, 1995), seedling growth and establishment are probably critical periods in the individual life cycle (Wilson et al, 1995). Therefore, seedling growth rate was examined with special care by measuring the length of the longest leaf four times: 6 (19 November), 9 (12 December), 15 (29 January), and 28 (19 May) wk from sowing.…”

We studied inbreeding depression in a perennial plant, Lychnis viscaria, in three populations differing in their inbreeding history and population size by measuring several traits at two nutrient levels over the plant's life cycle. The observed levels of inbreeding depression (cumulative inbreeding depression, from -0.057 to 0.629) were high for a plant with a mixed mating system. As expected, the population with a low level of isozyme variation expressed the least inbreeding depression for seed germination. Highest inbreeding depression for germination was found in the largest and genetically most variable population. No clear differences between populations in expression of inbreeding depression in the later life stages were found. The population level inbreeding depression varied with the nutrient conditions and among populations and life stages, but we found no evidence that inbreeding depression increased with lower nutrient availability. These results emphasize the importance of measuring inbreeding depression under several environmental conditions and over life stages.

“…It is found in most of central Europe, and its main distribution area extends in northern Scandinavia to 620 latitude but some isolated populations are found up to 680 latitude (Hulten 1971;Wilson et al 1995). In the surroundings of Jyvaskyla, in central Finland (62015'N, 25?45'E), L. viscaria occurs in its northern range in rather small and very isolated patches.…”

“…In the surroundings of Jyvaskyla, in central Finland (62015'N, 25?45'E), L. viscaria occurs in its northern range in rather small and very isolated patches. The average number of inflorescences per plant has been found to range from one to 50 with about 20-25 flowers on each inflorescence (Jennersten 1991;Wilson et al 1995). The flowers are protandrous having 10 anthers and five stigmas and normally carrying five petals.…”

“…We used the herb Lychnis viscaria L. as the study plant since it is partially self-incompatible (Wilson et al 1995) and mainly pollinated by long-tongued insect groups, particularly bumble bees and some lepidopterans (Kwak and Jennersten 1991;Wilson et al 1995; but see Jakobsson and Ågren 2014). Lychnis viscaria flowers between late May and late June, and each flower produces a fruit containing approximately 300−400 ovules (Kwak and Jennersten 1991).…”

Effects of landscape composition and configuration on pollination in a native herb: a field experiment

et al. 2015

View full text Add to dashboard Cite

Bumble bee abundance in agricultural landscapes is known to decrease with increasing distance from seminatural grasslands, but whether the pollination of bumble-bee-pollinated wild plants shows a similar pattern is less well known. In addition, the relative effects of landscape composition (landscape heterogeneity) and landscape configuration (distance from seminatural grassland) on wild plant pollination, and the interaction between these landscape effects, have not been studied using landscape-level replication. We performed a field experiment to disentangle these landscape effects on the pollination of a native herb, the sticky catchfly (Lychnis viscaria), while accounting for the proportion of oilseed rape across landscapes and the local abundance of bee forage flowers. We measured pollen limitation (the degree to which seed set is pollen-limited), seed set, and seed set stability using potted plants placed in landscapes that differed in heterogeneity (composition) and distance from seminatural grassland (configuration). Pollen limitation and seed set in individual plants did not respond to landscape composition, landscape configuration, or proportion of oilseed rape. Instead, seed set increased with increasing local bee forage flower cover. However, we found within-plant variability in pollen limitation and seed set to increase with increasing distance from seminatural pasture. Our results suggest that average within-plant levels of pollen limitation and seed set respond less swiftly than the within-plant variability in pollen limitation and seed set to changes in landscape configuration. Although landscape effects on pollination were less important than predicted, we conclude that landscape configuration and local habitat characteristics play larger roles than landscape composition in the pollination of L. viscaria.
