| 内容記述 | Cytological and ecological studies were made on Lycopodium clavatum in various habitats and localities of Japan. Among 729 individuals from 172 localities examined, 359 from 116 were of the diploid cytotype with 2n=68, 172 from 77 were of the triploid with 2n=102, and 198 from 77 were of the tetraploid with 2n=136. The three cytotypes showed similar karyotypes; the median: submedian: subterminal: terminal centromeric chromosome=30:20:25:25 of the total complement. The meiotic chromosome configuration was 34II in the diploids constantly and 68II in most of the tetraploids. In the triploids, the commonest was 36II+30I and 39% SMCs had trivalents. All populations studied were divided into three population types; the sole-type where only one cytotype occurred in a population, the mixed-type A where two or three cytotypes occurred in the same population but each in a different habitat, the mixed-type B where two or three cytotypes grew sympatrically and shared the same habitat. In the sole-type and mixed-type A, the diploids preferred humid, shady, stable places; the tetraploids open, sunny, unstable places; and the triploids were intermediate between the other two cytotypes. The mixed-type B occurred in places at the early phase of succession in a plant community. Each cytotype can progress successively towards occupying its optimum habitat, from the mixed-type B to the mixed-type A and finally to the sole type. These habitat preferences of each cytotype and successional changes were found uniformly throughout the Japanese archipelago. | |||||
