    BACKGROUND AND AIMS: Interspecific difference in pollinators (pollinator isolation) is important for reproductive isolation in flowering plants. Species-specific pollination by fungus gnats has been discovered in several plant taxa, suggesting that they can contribute to reproductive isolation. Nevertheless, their contribution has not been studied in detail, partly because they are too small for field observations during flower visitation. To quantify their flower visitation, we used the genus Arisaema (Araceae) because the pitcher-like spathe of Arisaema can trap all floral visitors. METHODS: We evaluated floral visitor assemblage in an altitudinal gradient including five Arisaema species. We also examined interspecific differences in altitudinal distribution (geographic isolation) and flowering phenology (phenological isolation). To exclude the effect of interspecific differences in altitudinal distribution on floral visitor assemblage, we established 10 experimental plots including the five Arisaema species on high- and low-altitude areas and collected floral visitors. We also collected floral visitors in three additional sites. Finally, we estimated the strength and contribution of these three reproductive barriers using the unified formula for reproductive isolation. KEY RESULTS: Each Arisaema species selectively attracted different fungus gnats in the altitudinal gradient, experimental plots, and additional sites. Altitudinal distribution and flowering phenology differed among the five Arisaema species, whereas the strength of geographic and phenological isolations were distinctly weaker than those in pollinator isolation. Nevertheless, the absolute contribution of pollinator isolation to total reproductive isolation was weaker than geographic and phenological isolations, because pollinator isolation functions after the two early-acting barriers in plant life history. CONCLUSIONS: Our results suggest that selective pollination by fungus gnats potentially contributes to reproductive isolation. Since geographic and phenological isolations can be disrupted by habitat disturbance and interannual climate change, the strong and stable pollinator isolation might compensate for the weakened early-acting barriers as an alternative reproductive isolation among the five Arisaema species.

    General decline of understory cover can result from increased abundance of and foraging pressure by deer. But population size and degree of aggregation can increase for unpalatable understory plants that escape foraging pressure. Clonal reproduction can enable unpalatable plant species to increase their population sizes while trending toward spatially aggregated distributions. However, the details of the relationship between clonal reproduction in unpalatable plants and their dynamics under intensive deer herbivory are not clear. We compared the population structures and spatial patterns of two coexisting unpalatable plant species, Arisaema ovale (with clonal reproduction) and A. peninsulae (without clonal reproduction) in a riparian forest intensively grazed by Sika deer, and examined the null hypothesis that the extent of spatial aggregation and local population size would not differ between the clonal and non-clonal Arisaema species. In a 0.36-ha plot, A. ovale had a larger population size (1087 individuals) with a higher abundance ratio of small plants (p < 0.01) than A. peninsulae (84 individuals). Analyses of spatial point processes showed that both populations were spatially aggregated (p < 0.05). The spatial aggregation of A. peninsulae, however, became weaker than that of A. ovale, when we excluded one dense patch originating from irregular seed dispersion. These results, excluding the aggregated distribution observed in A. peninsulae, suggested a substantial contribution of clonal reproduction to the expansion of the local A. ovale population following intensive grazing by Sika deer.

    Premise The genus Arisaema (Araceae) has rapidly diversified in Japan, and multiple species often coexist in the field. Although Japanese Arisaema species hybridize from artificial crossing, hybrid individuals are rare in mixed populations; suggesting the presence of effective pre-pollination barriers. We examined the following reproductive barriers between A. sikokianum and A. tosaense: habitat, phenology, and pollinator isolations. Methods Habitat isolation was examined by interspecific comparisons of microhabitat conditions at a mixed site and of altitude at the sampling site of herbarium specimens. Phenological isolation was evaluated by comparing seasonal transition in apparent spathe condition and frequency of insect visitation. Pollinator isolation was examined by comparing floral visitor assemblages between the two Arisaema species. To avoid overestimation of pollinator isolation due to seasonal changes in insect assemblages, we also compared visitor assemblages between natural and late-flowering A. sikokianum, where the latter was experimentally introduced and blooming with a natural A. tosaense population. Results Microhabitat conditions and sampling elevations of herbarium specimens overlapped between the two Arisaema species. At the population level, A. sikokianum and A. tosaense flowered for 39 and 52 days, respectively, with 13 days overlap. Insect visitation in A. sikokianum decreased before the seasonal overlap. Floral visitor assemblages differed between the two Arisaema species, while the difference between natural and late-flowering A. sikokianum was less distinct. Conclusions Phenological and pollinator isolation contribute to reproductive isolation between the two Arisaema species and should enable the two species to coexist in this area.

    The concern regarding the re-establishment of coppice forests has increased with respect to biodiversity conservation, bioenergy, and ecological services. To successfully restore the oak dominated coppices, understanding the factors affecting sprout regeneration is necessary because stump sprouts are the essential source of natural oak regeneration. In the present study, therefore, we sought to determine the stump sprout dynamics of the two widely distributed oaks in Japan, Quercus serrata and Q. acutissima, in relation to stump size, sprout characteristics, topographic factors, and canopy closure over a 4-year period following cutting in abandoned coppices. The study plot (40 x 90 m) was established in a coppice forest abandoned since the 1960s in western Japan. In winter 2013, canopy trees within and outside the plot were cut, then we collected the data of sprout origin position, sprout survival, sprout diameter, and length from 2014 to 2017. Four years after cutting, the proportion of surviving stumps decreased to 37% (n = 98) and 56% (n = 61) in Q. serrata and Q. acutissima, respectively. In both species, the Bayesian logistic mixed model showed that stump survival was not significantly affected by stump size and the examined environmental factors. The number of living sprouts per stump differed between Q. serrates (8.7 +/- 6.7) and Q. acutissima (5.1 +/- 4.6) after four years (P = 0.01). The number of sprouts per stump in both species tended to increase with stump diameter and was greater in convex area, but only significant for Q. acutissima. Dominant sprouts of Q. acutissima exhibited greater diameter and length than those of Q. saran, and the relative growth rate of sprouts in both species decreased with time after cutting. Dominant sprouts originating from a higher position on the stump grew better than those closer to the ground level. Sprout growth was negatively affected by sprout number per clump and positively affected by dead sprout number per stump, but only significant for Q. serrata. Light availability positively, although modestly, influenced sprout growth. Our data suggest that relying only on stump sprouts to restore the abandoned coppice stands dominated by the two species is insufficient because their stump survival rate was relatively low. Within the observed range of stump diameter, it may not be a factor responsible for the regeneration failure in the two species. Artificial thinning of small and suppressed sprouts may promote the growth of the remaining dominant sprouts.

    Rejuvenation by sprouting is a possible solution to prevent abandoned coppice forests in Japan from outbreaks of oak wilt disease. Applying this approach requires examining the sprouting capacity of large-sized oak trees. Therefore, the present study investigated the effects of stump size, sprout characteristics (emerging time and origin position), and environmental factors (slope, convexity, soil moisture, soil net nitrogen mineralization rate (Net-NMR) and canopy closure) on sprout regeneration of the two widely distributed oaks in Japan, Quercus serrata and Quercus acutissima, in the first growing season after cutting. In November 2013, a study plot (40x90m) was set, and canopy trees within the plot and edge areas were cut. We recorded sprout emergence, sprout origin position, sprout survival, and length from May to October 2014. Our data indicated that both species (ca. 60years old) have not yet lost their ability of sprouting. In Q. acutissima, the sprouting probability increased with light availability and was higher in concave area, and its number of living sprouts was positively related to stump diameter. In Q. serrata, the number of living sprouts increased with light availability. Sprouts emerged earlier and/or originated from the lower part of stump exhibited a higher survival probability. Emerging time substantially influenced sprout growth pattern and its effect followed a similar tendency in both species. Our results evidence that the ability of sprouting and the number of living sprouts might not be reduced in large-sized trees, and the increasing of light availability could promote sprout regeneration.
