Field evidence for bi‐directional sex change in the polygynous gobiid fish Trimma okinawaeNARA Subscribed
The social condition of bi‐directional sex change in the gobiid fish Trimma okinawae was investigated at Akamizu Beach, Kagoshima, Japan. Social groups of T. okinawae usually consisted of a large male and one or more smaller females. The number of females in the group was positively correlated with male body size and groups were usually separated from each other by 1–3 m. In total, 22 instances of female‐to‐male sex change and...
Interannual genetic heterogeneity of pollen pools accepted by Quercus salicina individualsNARA Subscribed
Since flowering often varies among years in wind‐pollinated woody species, the genetic composition of pollen pools accepted by seed parents can differ between years. The interannual heterogeneity of pollen flow may be important for maintaining genetic diversity within populations because it can increase genetic variation within populations and the effective sizes of the populations. In this study we examined heterogeneity, usi...
Genetic structure of Camellia japonica L. in an old‐growth evergreen forest, Tsushima, JapanNARA Subscribed
The spatial genetic structure of Camellia japonica was investigated, using microsatellite markers, in a 4‐ha permanent plot within an old‐growth forest. Spatial distribution of individuals was also assessed to obtain an insight into spatial relationships between individuals and alleles. Morisita’s index of dispersion showed that 518 C. japonica individuals in the plot were clumped, and Moran’s I spatial autocorrelation coeffic...
