“…This strategy was adopted by several species (Gatti et al, 2011;Saldaňa-Acosta et al, 2009;Valladares et al, 2002). The present results obtained from the middle successional A. truncatum do not appear to support this hypothesis: the root to shoot ratio was higher in CL-treated plants than in those subjected to CH or LH treatments, suggesting that under low light conditions, A. truncatum seedlings allocate more resources to the roots.…”

“…In addition to the root to shoot ratio, specific leaf area -the light-capturing area per unit of previously captured mass-is another important variable used to describe shade tolerance (Saldaňa-Acosta et al, 2009). In present study, the highest specific leaf areas of both species were detected under low light conditions (Fig.…”

“…A number of investigations have been conducted to examine plant morphological and physiological responses to variations in illumination (Gatti et al, 2011;Guo et al, 2013;Naramoto et al, 2006;Saldaňa-Acosta et al, 2009;Tobita et al, 2010;Valladares et al, 2002;Yamashita et al, 2000). In some of these studies, plants were subjected to low light illumination for some time and then were transferred to high light condition.…”

Abstract:In this study, we investigated responses of the mid-successional species Acer truncatum Bunge and the late-successional species Quercus variabilis Blume to three solar illumination conditions: (1) constant low light (CL), (2) constant high light (CH) and (3) low light first and high light afterwards (LH). The last treatment was to simulate a canopy opening. Both species exhibited increases in biomass, totally and in part, and decreases in leaf water content, specific leaf area and chlorophyll concentrations in LH treatment compared to CL treatment. For A. truncatum, exposure to high light condition (LH) increased crown area, and decreased root to shoot ratio, stem mass ratio and leaf perimeter. However, for Q. variabilis, LH treatment increased stem diameter at ground height, effective quantum yield, photochemical quenching and decreased maximum photosystem II quantum yield. The biomass allocation pattern did not change in Q. variabilis among three light conditions. With respect to newly developed leaves, no significant differences were found in leaf size of Q. variabilis between LH treatment and CH treatment while that of A. truncatum decreased in LH treatment. All chlorophyll fluorescence parameters in newly developed oak leaves in LH treatment increased compared to those of CH treatment while no difference was found for A. truncatum between LH and CH treatment. A. truncatum displayed a greater overall plasticity than Q. variabilis although the oak seedlings have a greater plasticity with respect to chlorophyll concentration and chlorophyll fluorescence parameters. A. truncatum should be a better candidate for vegetation recovery, especially in places with heterogeneous light conditions.

“…A high light environment after a large canopy disturbance can promote growth of seedlings of some species (Ashton 1995), while other species grow better in smaller canopy openings (Brown 1996). The light regime of the forest understory and gap edges favors seedling growth of the more shade-tolerant species (Saldana-Acosta et al 2009, Chazdon et al 2010. Thus, understanding the potential responses of tree species to environmental of interioredge-exterior gradient is critical to designing systems that maintain and facilitate recovery of biological diversity at interior-exterior gradient across the forest edge of tropical forest.…”

We investigated the environmental factors and tree species characteristics that are important for colonization of an interior-exterior gradient across the forest edge, for application to the restoration of abandoned shifting-cultivation areas in tropical montane forests in the Umphang Wildlife Sanctuar y, nor thwest Thailand. The relative impor tance of physical environment and recruit limitation was evaluated in relation to the regeneration traits of tree species. Three belt transect plots (150 m x 20 m) were established at the transition from secondary forest (edge interior) to open areas (edge exterior) of different ages (1, 3, and 5 years) after abandonment of shifting cultivation. We also set three belts (20 m x 50 m each) in a primary forest remnant. The species composition of canopy trees, regenerated seedlings, and saplings was studied, together with aspects of the physical environment. We found that it was difficult for primary forest species to effectively colonize the forest edge exterior, mostly due to recruitment limitations rather than the physical environment. Many of secondary forest species and generalists were also affected by recruitment limitation (significant negative correlation with the distance from forest edge), though they were also affected by factors related to the physical environment and forest structure and more abundant in open area. Only a few species, like Choerospondias axillaris (primary forest species), Wendlandia tinctoria (secondary forest species), Colona elobata, and Ficus hispida (generalist species) did not suggest recruitment limitation. These results suggested that natural regeneration of secondary forest and generalist species could be utilized as a first step in restoration expecting their facilitation effects for primary forest species.

“…Survival and growth of species in early successional environments may be predicted by their functional traits; a functional trait is a measurable property of the organisms that strongly influences its performance (McGrill et al 2006). For example, in the cloud forest, transplanted species with large leaves and high dry matter content (Saldaña-Acosta et al 2009) or in the rain forest, transplanted species with deep canopies (Martínez-Garza et al 2013b) showed higher performance in restoration plantings. On the other hand, tree species that recruit naturally early in succession have functional traits associated to high dispersal capacity, as small seed size (Lohbeck et al 2013).…”

Background. Minimal restoration intervention includes actions to stop disturbance so natural succession may take place whereas maximal intervention involves the establishment of plantings. Questions. To evaluate the success of minimal versus maximal restoration intervention, the performance of recruits and transplants was assessed. To this end, performance of 15 native tree species was predicted using life-history, their origin (recruits or transplants) and 12 plant functional traits. Study site and years of study. This study was carried out in pastures at Los Tuxtlas, Veracruz, Mexico in 5 years old restoration settings. Methods. Pioneer and non-pioneer species were planted in 16 30 × 30 m plots whereas natural recruitment was evaluated in plantings and at eight additional fenced plots. Results. Overall 15 species recruited or planted, pioneers had higher performance than non-pioneer. Transplant shock in terms of survival and height growth rates was overcome after 5 years probably as a result of increases in diameter growth rates. Conclusions. Tree species are divided in three groups to give recommendation for restoration: (1) Species in the Good recruiters group do not need to be transplanted; if seed sources are not close, we recommend direct seeding (i.e., Albizia purpusii, Cedrela odorata, Cecropia obtusifolia). (2) Species in the Good transplants group show very low or nil recruitment; they should be transplanted (i.e., Ochroma pyramidale, Ficus yoponensis, Cojoba arborea). (3) Species in the Poor transplants group should be transplanted but once a canopy has developed (i.e., Amphitecna tuxtlensis, Brosimum alicastrum, Bernoullia flammea). Key words: functional traits, Heliocarpus appendiculatus, life history, natural recruitment, transplant shock Desempeño de 15 especies de árboles tropicales reclutados o trasplantados en áreas de restauración ResumenAntecedentes. La mínima intervención de restauración incluye detener la perturbación para que la sucesión se lleve a cabo mientras que la máxima involucra el establecimiento de plantaciones. Preguntas. Para evaluar el éxito de la intervención mínima en comparación con la máxima se midió el desempeño de reclutas y trasplantes. Con este fin se buscó explicar el desempeño de 15 especies de árboles nativos mediante su historia de vida, su origen (reclutas o trasplantes) y 12 caracteres funcionales. Sitio de estudio y fechas. Este estudio se llevó a cabo en Los Tuxtlas, México dentro de un proyecto de restauración de 5 años. Métodos. Árboles pioneros y no-pioneros fueron plantados en 16 parcelas de 30 × 30 m; el reclutamiento natural se evaluó en las plantaciones y en ocho parcelas adicionales. Resultados. Incluyendo las 15 especies evaluadas, las pioneras tuvieron mejor desempeño que las no-pioneras. El stress del trasplante terminó después de 5 años, probablemente debido al incremento en diámetro. Conclusiones. Las especies han sido divididas en tres grupos para dar recomendaciones sobre su uso en restauración: (1) Las especies del grupo Buenos reclutas ...
