Nuclear and chloroplast microsatellite analysis ofAbies sachalinensisregeneration on fallen logs in a subboreal forest in Hokkaido, Japan

Abstract: Fallen logs are the main regeneration sites for Abies sachalinensis (Sachalin fir) in subboreal forests in Japan. We surveyed the spatial genetic structure of different demographic stages in a 4.29-ha natural population of A. sachalinensis. Genetic structure was significant at short distances throughout all stages in this wind-dispersed conifer. To evaluate the effects of fallen-log-dependent recruitment on demography and spatial genetic structure, we conducted parentage analysis of offspring with highly polym… Show more

“…These trends are consistent with previous studies related to inbreeding depression (Keller & Waller, 1996;Husband & Schemske, 1996). At the population level, F IS often decreases from the seedling stage to the mature tree stage (Hufford & Hamrick, 2003;Lian et al, 2008). For example, selfed or inbred progenies tend to be eliminated during the early demographic stages (Karkkainen et al, 1996;Kadomatsu et al, 1997;Isagi et al, 2007;Naito et al, 2005).…”

Selection of inbred individuals eventually affects genetic variation within the population as F IS often decreases from the seedling stage to the mature tree stage (Hufford & Hamrick, 2003;Lian et al, 2008). Statistical modeling enabled us to evaluate the effects of initial height, MLH, and site conditions on seedling longevity for the two species.…”

“…It has also been important to conserve the natural genetic resources and the within-population genetic diversity against potential depletion or contamination through overcutting or plantation practices. Highly polymorphic microsatellite (simple sequence repeat; SSR) markers have enhanced molecular studies of Japanese conifer species, in particular, genotypic discrimination of clones (e.g., HIRAO et al, 2006), gene flow in seed orchards and natural populations (e.g., MORIGUCHI et al, 2005;GOTO et al, 2005;IWAIZUMI et al, 2007;LIAN et al, 2008), and inter-population genetic structure (e.g., TAKAHASHI et al, 2005).…”
