Resilient Plant–Bird Interactions in a Volcanic Island Ecosystem: Pollination of Japanese Camellia Mediated by the Japanese White-Eye

<div><p>Observations of interspecies interactions during volcanic activity provide important opportunities to study how organisms respond to environmental devastation. Japanese camellia (<i>Camellia japonica</i> L.) and its main avian pollinator, the Japanese White-eye (<i>Zosterops japonica</i>), offer an excellent example of such an interaction as key members of the biotic community on Miyake-jima, which erupted in 2000 and continues to emit volcanic gases. Both species exhibit higher resistance to volcanic damage than other species. We examined the effects of volcanic activity on this plant–pollinator system by estimating pollen flow and the genetic diversity of the next generation. The results showed that despite a decrease in <i>Camellia</i> flowers, the partitioning of allelic richness among mother-tree pollen pools and seeds decreased while the migration rate of pollen from outside the study plot and the pollen donor diversity within a fruit increased as the index of volcanic damage increased. In areas with low food (flower) density due to volcanic damage, <i>Z. japonica</i> ranged over larger areas to satisfy its energy needs rather than moving to areas with higher food density. Consequently, the genetic diversity of the seeds (the next plant generation) increased with the index of volcanic damage. The results were consistent with previously published data on the movement of <i>Z. japonica</i> based on radio tracking and the genetic diversity of <i>Camellia</i> pollen adhering to pollinators. Overall, our results indicated that compensation mechanisms ensured better pollination after volcanic disturbance.</p></div

Study sites and patterns of vegetation.

<p>We established 0.3-ha plots at each of 6 study sites [Tubota (TU), Izu (IZ), Kamitsuki (K), Igaya (IG), Nanto-road 2 (N2), Nanto-road 4 (N4)] to assess how volcanic damage affected the ecosystem of Miyake-jima. Vegetation was categorized into six classes in order of increasing damage: 1, area covered by woody vegetation with no damage from the eruption; 2, areas in which woody vegetation was beginning to decline and be replaced by grassland; 3, area in which the forest had been reduced soon after the eruption, but grassland has begun to recover; 4, area in which the forest wood suffered heavy devastation following the eruption, and grassland is beginning to recover; 5, area in which the vegetation cover had been removed soon after the eruption and has not recovered; 6, poor vegetation area before the eruption (the area is residential or covered mainly by lava from the 1983 eruption) <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0062696#pone.0062696-Takahashi1" target="_blank">[21]</a>.</p

Estimations of pollen movements in 0.3-ha plots on Miyake-jima, Japan.

<p>Pollen flow distance indicate mean straight-line distance from mother tree to estimated pollen donor, which was calculated for each mother tree (<i>N</i> = 48) (SD). Migration rate of pollen and pollen donor diversity were calculated for each fruit (<i>N</i> = 165) (SD). Pollen donor diversity indicate that number of pollen donors per number of seeds within a fruit.</p
