6Tracking leaf area index and coefficient of light extinction over the harvesting cycle of black wattle显示文摘The amount of photosynthetic radiation intercepted by a crop is a function of the incident solar radiation on the plants, the leaf area index(L_(AI)), and the light extinction coefficient(k). We quantified L_(AI) and k in stands of black wattle(Acacia mearnsii De Wild.) over a 7-year growth cycle at two locations in the state of Rio Grande do Sul, Brazil. Our study was conducted in commercial stands in agroecological regions with high densities of black wattle plantations. L_(AI)was calculated as the ratio between the leaf area of a tree and its planting space, and k was derived from Beer's law. L_(AI)depends on the planting site and stand age. Between the two sites, the L_(AI) was similar over time, the amount of variation differed. Values of k depended only on stand age, with the highest average observed for stands up to 5 years old. The trend of k during the plantation cycle was inversely proportional to L_(AI)and was correlated with L_(AI), leaf area, leaf dry mass, canopy volume, height, branches dry mass, total dry mass, and crown diameter.Aiexandre Behling Carlos Roberto Sanquetta Ana Paula Dalla Corte Sylvio Pellico Netto Aurelio Lourenco Rodrigues Braulio Otomar Caron Augusto Arlindo Simon 2016Journal of Forestry Research2016,27,6:1

9Population structure of Araucaria angustifolia under distinct forest protection status:implications for management and conservation显示文摘Araucaria angustifolia is the dominant coniferous species in Brazil,a long-lived pioneer species and a supplier of valuable timber and non-timber products,which gives it key-species status.This study examines how A.angustifolia population structure affects the stand structure,and whether these relationships differ between protected and unprotected areas.The study was carried out on two protection status forests(national forest and urban forest)in a region of Atlantic mixed forest in ParanáState,southern Brazil.Skewness coefficient and the Weibull shape parameter described the population structure and its effects on species diversity and biomass stock.Population diameter distribution differed significantly between forests,with unbalanced structure in both,although regeneration was more abundant in the protected area.Skewness positively affected aboveground biomass whereas shape negatively affected it and species diversity.These relationships differed between protected and unprotected stands.The effect of A.angustifolia populations on stand structure was conditioned on protection status.Old-growth populations may have lower diversity and biomass stock even supporting large trees.Consequently,old-growth forests,can lead to wood loss through mortality,senescence,and declining populations,representing the waste of a valuable timber resource.These findings provide useful knowledge for forest management,species conservation,and the carbon market.Vinicius Costa Cysneiros Allan Libanio Pelissari Sylvio Pellico Netto Sebastiao do Amaral Machado Afonso Figueiredo Filho 2023Journal of Forestry Research2023,34,5:0
10Predicting the dynamics of a native Araucaria forest using a distance- independent individual tree-growth model显示文摘Background: In recent decades, native Araucaria forests in Brazil have become fragmented due to the conversion of forest to agricultural lands and commercial tree plantations. Consequently, the forest dynamics in this forest type have been poorly investigated, as most fragments are poorly structured in terms of tree size and diversity.Methods: We developed a distance-independent individual tree-growth model to simulate the forest dynamics in a native Araucaria forest located predominantly in southern Brazil. The data were derived from 25 contiguous plots(1 ha) established in a protected area left undisturbed for the past 70 years. The plots were measured at 3-year intervals from their establishment in 2002. All trees above a 10-cm diameter at breast height were tagged, identified as to species, and measured. Because this forest type comprises hundreds of tree species, we clustered them into six ecological groups: understory, subcanopy, upper canopy shade-tolerant, upper canopy light-demanding, pioneer, and emergent. The diameter increment, survival, and recruitment sub-models were fitted for each species group, and parameters were implemented in a simulation software to project the forest dynamics. The growth model was validated using independent data collected from another research area of the same forest type. To simulate the forest dynamics, we projected the species group and stand basal areas for 50 years under three different stand-density conditions: low, average, and high.Results: Emergent species tended to grow in basal area, irrespective of the forest density conditions. Conversely,shade-tolerant species tended to decline over the years. Under low-density conditions, the model showed a growth tendency for the stand basal area, while under average-density conditions, forest growth tended to stabilize within30 years. Under high-density conditions, the model indicated a decline in the stand basal area from the onset of the simulation, suggesting that under these conditions, the forest has already reached its maximum-stock capacity.Conclusions: The model validation using independent data indicated close agreement between the observed and estimated values, suggesting the model is consistent in projecting species-group and stand growth. The methodology used in this study for developing the growth model should be tested in other species-rich forests.Enrique Orellana Afonso Figueiredo Filho Sylvio Pellico Netto Jerome Klaas Vanclay 2016Forest Ecosystems2016,3,3:0
