Summary 0We used isozyme variation to examine the genet structure of Uvularia perfoliata patches in gap and closed canopy habitats in a temperate deciduous forest in Mary! land\ USA[ 1 A large patch in a gap habitat was composed of a small number of widely spread genets with many ramets\ and a large number of genets with more restricted dis! tribution and few ramets[ Genets with many ramets were patchily distributed at a metre scale[ Analysis of genet structure on a scale of square centimetres\ however\ revealed that the genets were highly intermingled with no clear boundaries between them[ The presence at both scales of sampling of many genets with unique multilocus genotypes indicated continuing genet recruitment within the population[ 2 In the closed canopy habitat\ the patches examined were each composed of a single unique multilocus genotype\ suggesting that each had developed by asexual propagation following the establishment of a single genet[ 3 The clonal structure of U[ perfoliata patches in both gap and closed canopy habitats therefore appears to depend on recruitment patterns of genets[ Populations in closed canopy habitats are characterized by a {waiting| strategy\ in which asexual ramet production maintains populations until genet recruitment by seed production can occur under the more optimal conditions associated with canopy gaps[ Extended sampling suggests that the genetic diversity of U[ perfoliata populations is primarily controlled by the disturbance regime of the forest canopy[ Keywords] clonal diversity\ gap\ genet structure\ genetic variation\ ramet\ spatial structure\ Uvularia perfoliata Journal of Ecology "0888# 76\ 133Ð146

“…2). The mean population growth rate (l) was 0.687 (Table 2) and this value was considerably smaller than the growth rates of other woodland herbs (Bierzychudek 1982;Kinoshita 1987;Nault & Gagnon 1993;Silvertown et al 1993;Hori et al 1995). This shows that the population size will decrease remarkably in the future.…”

The population structure and dynamics of Ainsliaea apiculata, a forest understory evergreen herb widely distributed in Japan, was examined in a Chamaecyparis obtusa forest in Ibaraki Prefecture, central Japan (36Â°51′N, 140Â°33′E; 750 m a.s.l.). The mean population growth rate (λ) calculated from the transition matrices for 4 years was 0.69 per year, predicting that the population size will decrease remarkably. There was a significant positive correlation between the survival of old leaves and the growth of new shoots in the following year. The shoots, especially new leaves, were damaged severely by herbivores (caterpillars of Leioptilus sp.). The survival rate of leaves formed in the previous spring to the next spring was remarkably low (41–54%). The growth of new shoots depended mainly on the reserves contained in old shoots, especially those in old leaves. New shoots of A. apiculata began to develop in spring, even though they were formed in autumn of the previous year. A defoliation experiment also showed that the removal of old shoots at the beginning of the growing season significantly inhibited the growth of new shoots. Damage to old shoots by herbivores severely influenced the growth and population dynamics of A. apiculata.
