“…The overall distribution of clones in accordance with their size (i.e., the predominance of numerous small clones over few large ones) was in the agreement with expectations [33] and was comparable to other similar studies [11,34,35]. The distribution can likely be a consequence of species' post-fire recovery strategies.…”

By performing a high-resolution spatial-genetic analysis of a partially clonal Salvia brachyodon population, we elucidated its clonal architecture and seedling recruitment strategy. The sampling of the entire population was based on a 1 × 1 m grid and each sampled individual was genotyped. Population-genetic statistics were combined with geospatial analyses. On the population level, the presence of both sexual and clonal reproduction and repeated seedling recruitment as the prevailing strategy of new genets establishment were confirmed. On the patch level, a phalanx clonal architecture was detected. A significant negative correlation between patches’ sizes and genotypic richness was observed as young plants were not identified within existing patches of large genets but almost exclusively in surrounding areas. The erosion of the genetic variability of older patches is likely caused by the inter-genet competition and resulting selection or by a random die-off of individual genets accompanied by the absence of new seedlings establishment. This study contributes to our understanding of how clonal architecture and seedling recruitment strategies can shape the spatial-genetic structure of a partially clonal population and lays the foundation for the future research of the influence of the population’s clonal organization on its sexual reproduction.

“…Similarly to many climbers, the three species studied here are naturally clonal to various degrees. Both H. helix and W. floribunda produce dimorphic long shoots, i.e., orthotropic climbing shoots and plagiotropic creeping shoots (stolons in the latter species) and C. orbiculatus produces belowground shoots that exhibit plagiotropic growth and explore the area eventually establishing clonal populations (Sakai et al 2002;Williams and Timmins 2003;Metcalfe 2005;Mori et al 2018). In this study, plagiotropic shoots were produced by all species but belowground shoots described elsewhere were not observed in C. orbiculatus.…”

Key message In some lianas the use of trellis modifies within-plant biomass allocation and stimulates growth, however in other species trellis use may negatively affect growth indicating a cost associated with climbing. Abstract In order to improve access to light, lianas use other plants as climbing trellises. Whereas in shaded lianas climbing a trellis may enhance biomass gain by increasing leaf-level irradiance, we suspected that trellis use may also stimulate growth by triggering modifications in whole-plant allocation of biomass and nitrogen. We evaluated responses to trellis in three temperate lianas: Hedera helix, Celastrus orbiculatus and Wisteria floribunda. Lianas were grown outdoors in 120-L barrels and with ample space, with and without trellises. Biomass and nitrogen accumulation, distribution patterns and total stem length were determined after three and four seasons. Responses were adjusted for individual plant biomass. Liana responses to trellises were species-specific. In W. floribunda trellis use enhanced growth, consistently with the increased leaf mass fraction and leaf area ratio while biomass distribution to roots was reduced. Biomass distribution to stems and total stem length were increased by trellis use. In contrast, growth and biomass distribution in C. orbiculatus were not altered by trellis use. In H. helix growth was reduced in plants climbing on trellises in comparison with plants creeping on the ground, but biomass distribution pattern was not altered. Moreover, supported H. helix plants accumulated less nitrogen than did unsupported plants, suggesting a less efficient uptake of this nutrient. The ability to plastically modify growth and allocation patterns in response to trellis found in some lianas may constitute an important aspect of their ecological strategy. In other species, however, the switch to climbing may incur physiological costs resulting in lower growth.

“…The spatial distributions of multi-stem genets identified only at the on-tree stage are indicated by red polygons connecting each stem. The clonal structure of W. floribunda at the on-tree stage was obtained from Mori et al (2018). At the on-floor stage, sampled individuals are represented by small squares, with empty squares representing single-stem genets and multi-stem genets indicated by colored polygons.…”

“…However, studies on the clonality of liana species both at the on-tree and the onfloor stages using genetic tools are surprisingly limited. Mori et al (2018) previously evaluated the clonal structure of a liana species (Wisteria floribunda [Willd.] DC.)…”

Lianas are important components of forest communities with a considerable impact on overall forest structure and function. Lianas are characterized by extensive clonal reproduction on the forest floor, which is important for their establishment and growth. Previous studies have suggested that clonal reproduction strategies vary substantially among liana species; however, few studies have quantitatively evaluated the clonality strategy in multiple co-occurring liana species. The primary objective of the present study was to evaluate the relative contribution of clonal reproduction and to understand the clonal proliferation processes in co-occurring liana species by assessing both small stems on the forest floor and mature stems that climbed trees. The clonal reproduction strategy in four common liana species (stem twiner: Wisteria floribunda; root climbers: Schizophragma hydrangeoides, Euonymus fortunei and Rhus ambigua) in a 6-ha plot and a belt transect within an old-growth temperate forest in central Japan was evaluated using genetic analysis. The contribution of clonal reproduction was smaller in root climbers than in W. floribunda. All W. floribunda genets with small ramets in the understory had genetically identical ramets that climbed trees, whereas few such ramets were found in root climbers. This indicates that W. floribunda mature ramets laterally produce small ramets via clonal proliferation, whereas seedlings of root climbers grow horizontally to climb trees. The results indicate that the clonal reproduction processes differ greatly among lianas and the clonal growth in lianas plays a contrasting role in their life-history strategy.
