“…However, several criteria should be considered when applying natural regeneration (Evans 1988;Harmer et al 1997): the quality and suitability of the parent crop; supply of viable seed; the presence of advance regeneration seedlings, which are present before harvesting of the mature trees; suitability of the forest floor for germination; survival and establishment of young seedlings; competition from weeds and browsing damage. Several studies have focused on natural regeneration of deciduous (i.e., Harmer et al 1997Harmer et al , 2005Harmer and Morgan 2007), coniferous (see Kerr 2000 for review) or evergreen broad-leaved (i.e., Wu et al 2008) forests. In deciduous trees, and in particular in beech, under natural regeneration the sapling stage is usually followed by a transition thicket stage prior to development of a young high-growing forest, that usually is initiated in the forestry practice by selective clearing measures.…”

Beech forests naturally regenerating from clear-cutting can exhibit different microclimates depending on size of saplings and stem density. When beech trees are young and stem density is low, the level of radiation inside the ecosystem reaching the soil surface is high; consequently, air and soil temperatures rise and the soil water content may decrease. These microclimatic parameters presumably will affect the anatomy, photosynthesis, and carbon metabolism of beech leaves. We studied the morphology and physiology of sun and shade leaves of beech trees differing in age and growing within clear-cut areas with distinct microclimate. Results were compared with those of adult trees in an unmanaged forest. We selected a stand clear-cut in 2001 (14,000 trees ha -1 ), another clearcut in 1996 (44,000 trees ha -1 ) and an unmanaged forest (1,000 trees ha -1 ). Photosynthetic photon flux density (PPFD) incident on sun leaves, air temperature, soil moisture, and soil temperature within the forests affected water status and carbohydrate storage in all trees. As trees became older, PPFD also influenced pigment composition and Rubisco activity in sun leaves. On the other hand, shade leaves from the oldest trees were the most sensitive to PPFD, air temperature, and soil moisture and temperature inside the forest. Contrariwise, microclimatic parameters slightly affected the physiology of shade leaves of the beech in the stand with the highest light attenuation. Air and soil temperatures were the parameters that most affected the photosynthetic pigments and carbohydrate storage in shade leaves of the youngest trees.

“…Importance values can be applied to detect dominant species in different communities, especially along ecological gradients (Greig‐Smith, 1983; Henkel, Chambers, & Baker, 2016; Kent, 2012). In practice, dominants are often defined as those plant groups with high importance values (Gonmadje et al., 2011; Khairil, Juliana, Nizam, Wan Juliana, & Nizam, 2014; Schmook, 2010; Wu, Shinzato, Kudo, Ishigaki, & Aramoto, 2008). …”

Dominant species significantly affect interspecific relationships, community structure, and ecosystem function. In the field, dominant species are often identified by their high importance values. Selective foraging on dominant species is a common phenomenon in ecology. Our hypothesis is that dominant plant groups with high importance values are more susceptible to leaf‐mining insects at the regional level. Here, we used the Saihanwula National Nature Reserve as a case study to examine the presence–absence patterns of leaf‐mining insects on different plants in a forest‐grassland ecotone in Northeast China. We identified the following patterns: (1) After phylogenetic correction, plants with high importance values are more likely to host leafminers at the species, genus, or family level. (2) Other factors including phylogenetic isolation, life form, water ecotype, and phytogeographical type of plants have different influences on the relationship between plant dominance and leafminer presence. In summary, the importance value is a valid predictor of the presence of consumers, even when we consider the effects of plant phylogeny and other plant attributes. Dominant plant groups are large and susceptible targets of leaf‐mining insects. The consistent leaf‐mining distribution pattern across different countries, vegetation types, and plant taxa can be explained by the “species‐area relationship” or the “plant apparency hypothesis.”

“…Similar results were also found in an EBLF restocked by natural regeneration after clear-cuttingburning on Iriomote Island, Okinawa, Japan. Wu et al (2008) reported that S. bracteata was present in abundance in both clear-cutting-burning and clear-cutting-only plots (37 and 46 individuals, respectively) before treatment; however, it was absent after the two treatments followed by 20 years of natural regeneration. The more drastic the silvicultural treatments, the greater the decrease in shade-tolerant species.…”

“…With the rapid development of tourism in Okinawa in recent decades, conservation of such unique forest resources in Japan has been emphasized and is now an urgent project aimed at protecting the EBLFs (Shinzato et al 1995(Shinzato et al , 2000. To realize these objectives, and to establish working techniques of forest management, experimental studies on clear-cutting (Shinzato et al 2000;Wu et al 2008), strip clear-cutting (Wu et al 2012), and selective logging (Shinzato et al 1995;Wu et al 2006) in EBLF followed by natural regeneration were carried out. Since the selective logging system is relatively new to the region, we do not know enough about the dynamics of these types of forests after selective logging.…”
