“…The results indicated more edge effect influence in younger stands, in accordance with Harper, et al [61]. In the case of older stands, the growth response of edge trees was similar to the results obtained by Genet and Pothier [29] for black spruce and balsam fir mixed stands in old-growth irregular forest.…”

“…Growth differences between edge and interior trees were correlated with the measured CI i ( Figure 4); this relationship has been reported in the literature [26,29,68]. Edge trees in younger stands of DS showed the lowest competition values, and it was the studied shelterwood with the highest growth response.…”

“…We speculate that the depth of the edge effect will be higher in older than younger stands due to less density, and in treatments with tree selection and high mortality a.c. In future investigations, measuring the tree distance from trails, as in Genet and Pothier [29], could be added to our methodology for a more precise evaluation.…”

“…The ecological conditions at the edges of trails are substantially different to the interior of the residual strip: more accessibility to nutrients, higher lateral light and wind exposure [25][26][27][28]. Phenomena such as inter-tree competition and mortality may therefore be modified [28][29][30]. Residual trees on the edges of trails will likely thus have a higher growth response after cutting than trees located inside the strip.…”

Partial cutting is thought to be an alternative to achieve sustainable management in boreal forests. However, the effects of intermediate harvest intensity (45%-80%) on growth remain unknown in black spruce (Picea mariana (Mill.) B.S.P.) stands, one of the most widely distributed boreal species with great commercial interest. In this study, we analysed the effect of three experimental shelterwood and one seed-tree treatments on tree radial growth in even-aged black spruce stands, 10 years after intervention. Our results show that radial growth response 8-10 years after cutting was 41% to 62% higher than in untreated plots, with stand structure, treatment, tree position relative to skidding trails, growth before cutting and time having significant interactions. The stand structure conditioned tree growth after cutting, being doubled in younger and denser stands. Tree spatial position had a pronounced effect on radial growth; trees at the edge of the skidding trails showed twice the increase in growth compared to interior trees. Dominant trees before cutting located close to the skidding trails manifested the highest growth response after cutting. This research suggests that the studied treatments are effective to enhance radial wood production of black spruce especially in younger stands, and that the edge effect must be considered in silvicultural management planning.

“…Understanding various ecological mechanisms and processes that influence species assemblage are critical to get deep insights on species associations and community structure. Analyzing the spatial patterns of species are therefore of main interest in community ecology to figure out the underlying mechanisms and to test different ecological theories [2][3][4]. Several processes-such as competition or facilitation, dispersal limitation, habitat preference, Janzen-Connell hypothesis-that have been proposed for explaining community structure and species coexistence in species-rich forests are mainly based on spatial characteristics of species associations [5].…”

Structural complexity and local biodiversity of species-rich tropical forests can be characterized by their spatial patterns, which contribute to species intra-and interspecific interactions. Aiming to describe spatial patterns of species at fine spatial scales, we applied the quantitative analyses based on the relationships of nearest neighbors of conspecific and heterospecific trees. In a two-hectare plot of a tropical broadleaved forest stand in central Vietnam with minimal human influence, all tree individuals with diameter at breast height ≥ 2.5 cm were mapped and their characteristics were recorded. We applied two different types of analyses: (1) Intraspecific structural characteristics using nearest neighbor statistics; (2) overall interspecific associations through a classification scheme based on bivariate nearest neighbor distribution function D 12 (r) and Ripley's K function K 12 (r). The findings showed that: (1) Most of studied species in the forest were highly mixed with other species, while conspecifics were regular to aggregated distribution at small spatial scales. Tree individuals with different diameter values were surrounded by heterospecific trees; (2) The majority of 306 species-species pairs showed spatial independence (66.7%), whereas 29.8% of all species showed an overall positive association and negative association consisted only a small percentage (3.5%) up to spatial scales of 50 m. We found significant evidences of the main ecological theories such as dispersal limitation, Neutral theory, Janzen-Connell hypothesis, and other effects like the stochastic dilution. We suggest using both the bivariate distribution of the structural parameters and the spatial point pattern analysis based on nearest neighbor distance as advantageous approaches for further understanding of population structure, as well as discovering and protecting biodiversity in the future.
