TECHNOLOGICAL CHARACTERIZATION OF Mezilaurus itauba WOOD: APPLICATION AND MACHINING TESTS

Brazil has several forest species that can be used for sustainable wood production. However, finding materials with technological quality is still a challenge. Wood is an excellent building material, however, there are few studies that have investigated the technological characterization, machining and processing of these species, including Mezilaurus itauba (Meisn.) Taub. Ex Mez. Thus, this study aimed to evaluate the technical characteristics and application potential of M. itauba wood from two distinct commercial lots, by analyzing its mechanical properties and performing machining tests.  For this, static bending, dynamics and machining tests were carried out. The perpendicular compression tests of the evaluated fibers presented mean values of 9899.77 Mpa and 10670.74 Mpa for the elasticity module of lot 1 and lot 2, respectively. The average value observed for the L1 rupture module was 96.02 Mpa, while for L2 it was 113.85 Mpa. For the shear tests, low variation was observed between the specimens as well as between the evaluated lots. As for machining tests, M. itauba wood was classified as excellent for manufacturing furniture and internal openings. The M. itauba lots have acceptable mechanical strength, and the density is indicated for structural works, as well as for manufacturing furniture and interiors

LEVANTAMENTO FLORÍSTICO E PARÂMETROS FITOSSOCIOLÓGICOS DA RESTINGA NA LOCALIDADE DE MORRO DOS CONVENTOS, ARARANGUÁ-SC

Estudou-se a composição florística e parâmetros fitossociológicos da restinga herbácea na localidade de Morro dos Conventos, Araranguá, Santa Catarina. As restingas despertam grande interesse no meio científico por apresentarem fragilidade e grande diversidade de espécies vegetais. Para a florística utilizou-se o método expedido por caminhamento e para a fitossociologia o método de parcelas em três áreas distintas: dunas frontais, internas e baixadas, onde a vegetação é predominantemente herbácea. Foram utilizadas 20 parcelas de 2m x 2m distribuídas ao longo de um transecto de 120m, com 4m de distância entre as parcelas. A cobertura de cada espécie foi estimada pela escala de Causton. A identificação taxonômica seguiu o sistema proposto por APG IV (BYNG et al., 2016) para angiospermas. Foram registradas 15 espécies distribuídas em nove famílias botânicas. Dentre as famílias encontradas Asteraceae (6) apresentou a maior riqueza específica, seguida de Poaceae (2). Essas famílias apresentam polinização e dispersão facilitada pelo vento, que é determinante na distribuição das espécies no ambiente de dunas frontais. As espécies com maiores valores de importância foram Panicum racemosum, Hydrocotyle bonariensis, Oxypetalum tomentosum e Ipomea pes-caprae, distribuídas predominantemente nas dunas frontais, sendo que Panicum racemosum e Ipomea pes-caprae são descritas na literatura como importantes fixadoras de dunas.Palavras-chave: Restinga.

Phytosociological parameters of a fragment of mixed ombrophilous forest in regeneration after burning in the municipality of Segredo

The natural regeneration after natural or anthropogenic disturbances is an important element to reestablishing shrubby-arboreal species, that is, in the restoration of abundance. To the analysis of the floristic composition and some phytosociology parameters of one three years old clearing that was burned in a mixed ambrofila forest near Segredo, RS, was sampled 16 parts measuring 2m x 2m, totaling 64 m². Was found 240 individuals belonging to 42 shrubby-arboreal species. Therefore naturally trough processes of regeneration, the environment is covering himself, showing notable abundance. The species diversification may be contributing to the formation of different ecological guilds, which will facilitate in a time range, the gradual restoration of the degraded area that can be managed to achieve higher success.The present work aims to describe the structure and floristic composition of the natural regeneration in a clearing of a Fragment of Mixed Ombrophilous Forest that underwent an intervention by burning after three years in the Municipality of Segredo, Rio Grande do Sul State, Brazil. We sampled 16 plots of 2 x 2 m, totaling 64 m2. It was established that all plants with height greater than 0.3 m were included as criterion in the floristic survey. We found 240 plants belonging to 42 arboreal-shrub species

Estruturação espacial de traços funcionais de espécies arbóreas em função da distância da borda em Floresta Alto-Montana no sul do Brasil

We aimed to evaluate the functional organization of tree species in an Upper-Montane Araucaria Forest remnant, in the municipality of Urubici, Santa Catarina state. We tested the following hypothesis: the species present a high functional heterogeneity that is spatially structured as a function of the remnant edge distance. To determine the most abundant tree species, we plotted a 20 x 100 m transect, perpendicular to the fragment edge, where all trees with diameter at breast height (dbh) ≥ 5 cm were sampled. For the most abundant species, the functional traits were characterized: wood density (DM), leaf area (AF), specific leaf area (AFE) and maximum potential height (Hmax). The community weight mean values of functional traits (CWM) and functional diversity (RaoQ) were determined. The data were analyzed by Principal Component Analysis (PCA) and by Mantel Correlogram. While PCA axis 1 summarized a functional gradient related to Hmax and AFE, axis 2 indicated a variation related to DM and AF. Moreover, the edge distance significantly influenced the leaf traits and the functional diversity. At the edge, which is the environment where the vegetation is most exposed to frost, lower functional diversity was observed, with the predominance of species with small leaves. We concluded that the studied species are not functionally homogeneous and that the functional organization is spatially structured according to the edge distance.O presente estudo visou avaliar a organização funcional de espécies arbóreas em um remanescente de Floresta Ombrófila Mista Alto-Montana no município de Urubici, SC. A hipótese de que as espécies avaliadas apresentam elevada heterogeneidade funcional e que é espacialmente estruturada em função da distância da borda do remanescente foi testada. Para a determinação das espécies mais abundantes do fragmento, foi alocada uma transecção (20 x 100 m) perpendicular à borda do fragmento, em que foram amostradas as árvores com diâmetro a altura do peito (DAP) ≥ 5 cm. Para as espécies mais abundantes, foram caracterizados os seus traços funcionais: densidade da madeira (DM), área foliar (AF), área foliar específica (AFE) e altura máxima potencial (Hmax). Foram determinados os valores médios dos traços ponderados para a comunidade (CWM) e a diversidade funcional (RaoQ). Os dados foram analisados por meio de uma Análise de Componentes Principais (PCA) e por meio de correlograma de Mantel. Enquanto o eixo 1 da PCA sintetizou um gradiente funcional relacionado com a Hmax e AFE, o eixo 2 indicou uma variação relacionada com a DM e a AF. Além disso, observou-se estruturação espacial dos traços foliares (AF e AFE) e da diversidade funcional. Na borda, que é o ambiente onde a vegetação está mais exposta à geada, foi observada menor diversidade funcional, com a predominância de espécies com folhas pequenas. Assim, foi possível concluir que as espécies estudadas não são funcionalmente homogêneas e que a organização funcional é espacialmente estruturada em função da distância da borda

Traços funcionais e performance de espécies arbóreas em uma Floresta Ombrófila Mista no Planalto Sul-Catarinense

We aimed to describe the functional traits of the tree species of a Mixed Ombrophilous Forest fragment in the “Planalto Sul-Catarinense” region and to test if function traits predict tree species demographic rates. For the most abundant species, we determined the functional traits - leaf area (AF), specific leaf area (AFE), wood basic density (DM) and maximum potential height (Hmax) – and demographic rates – mortality, recruitment, gain and loss of basal area, turnover and net changes. We analyzed the data through Principal Component Analysis (PCA) and Generalized Least Square (GLS) models. The data showed that the species have a high functional heterogeneity, mainly in relation to Hmax, AFE (PCA - Axis 1), and DM (PCA - Axis 2).  Demographic rates were only affected by Hmax and AFE. We concluded that (i) the variation of species functional traits synthesized a spectra of ecological strategies related to the distribution of species along forest vertical profile and in areas with different times post-disturbance; and that (ii) the demographic rates of the species were predicted by the functional traits that indicated species ability to colonize the forest understory.O presente trabalho teve como objetivo a caracterização funcional de espécies arbóreas de um fragmento de Floresta Ombrófila Mista no Planalto Sul-Catarinense, bem como determinar se os traços funcionais afetam as taxas demográficas das mesmas. Para as espécies mais abundantes do fragmento foram caracterizados os traços funcionais - área foliar (AF), área foliar específica (AFE), densidade básica da madeira (DM) e altura máxima potencial (Hmax) – e suas taxas demográficas – mortalidade, recrutamento, ganho e perda em área basal, rotatividade e mudança líquida. Os dados foram analisados por meio da Análise de Componentes Principais (PCA) e modelos do tipo Mínimo Quadrado Generalizado (GSL). Os resultados evidenciaram que as espécies apresentam elevada heterogeneidade funcional, principalmente no que se refere a Hmax, AFE (PCA – Eixo 1) e DM (PCA - Eixo 2). As taxas demográficas das espécies foram influenciadas de forma significativa apenas por Hmax e AFE. Conclui-se que: i) as variações dos traços funcionais das espécies sintetizam espectros de estratégias ecológicas relacionadas ao particionamento do perfil vertical da floresta e a capacidade de se desenvolverem em áreas com diferentes tempos pós-distúrbios; e que, ii) os traços funcionais que indicaram a capacidade das espécies colonizarem o sub-bosque foram preditores das taxas demográficas das espécies

Although xylem embolism resistance thresholds (for example, Ψ50) and hydraulic safety margins (for example, HSM50) are important predictors of drought-induced mortality risk3-5, little is known about how these vary across Earth's largest tropical forest. Here, we present a pan-Amazon, fully standardized hydraulic traits dataset and use it to assess regional variation in drought sensitivity and hydraulic trait ability to predict species distributions and long-term forest biomass accumulation. Parameters Ψ50 and HSM50 vary markedly across the Amazon and are related to average long-term rainfall characteristics. Both Ψ50 and HSM50 influence the biogeographical distribution of Amazon tree species. However, HSM50 was the only significant predictor of observed decadal-scale changes in forest biomass. Old-growth forests with wide HSM50 are gaining more biomass than are low HSM50 forests. We propose that this may be associated with a growth-mortality trade-off whereby trees in forests consisting of fast-growing species take greater hydraulic risks and face greater mortality risk. Moreover, in regions of more pronounced climatic change, we find evidence that forests are losing biomass, suggesting that species in these regions may be operating beyond their hydraulic limits. Continued climate change is likely to further reduce HSM50 in the Amazon6,7, with strong implications for the Amazon carbon sink.Publisher PDFPeer reviewe

Crown-Level Structure and Fuel Load Characterization from Airborne and Terrestrial Laser Scanning in a Longleaf Pine (<i>Pinus palustris</i> Mill.) Forest Ecosystem

Airborne Laser Scanners (ALS) and Terrestrial Laser Scanners (TLS) are two lidar systems frequently used for remote sensing forested ecosystems. The aim of this study was to compare crown metrics derived from TLS, ALS, and a combination of both for describing the crown structure and fuel attributes of longleaf pine (Pinus palustris Mill.) dominated forest located at Eglin Air Force Base (AFB), Florida, USA. The study landscape was characterized by an ALS and TLS data collection along with field measurements within three large (1963 m2 each) plots in total, each one representing a distinct stand condition at Eglin AFB. Tree-level measurements included bole diameter at breast height (DBH), total height (HT), crown base height (CBH), and crown width (CW). In addition, the crown structure and fuel metrics foliage biomass (FB), stem branches biomass (SB), crown biomass (CB), and crown bulk density (CBD) were calculated using allometric equations. Canopy Height Models (CHM) were created from ALS and TLS point clouds separately and by combining them (ALS + TLS). Individual trees were extracted, and crown-level metrics were computed from the three lidar-derived datasets and used to train random forest (RF) models. The results of the individual tree detection showed successful estimation of tree count from all lidar-derived datasets, with marginal errors ranging from −4 to 3%. For all three lidar-derived datasets, the RF models accurately predicted all tree-level attributes. Overall, we found strong positive correlations between model predictions and observed values (R2 between 0.80 and 0.98), low to moderate errors (RMSE% between 4.56 and 50.99%), and low biases (between 0.03% and −2.86%). The highest R2 using ALS data was achieved predicting CBH (R2 = 0.98), while for TLS and ALS + TLS, the highest R2 was observed predicting HT, CW, and CBD (R2 = 0.94) and HT (R2 = 0.98), respectively. Relative RMSE was lowest for HT using three lidar datasets (ALS = 4.83%, TLS = 7.22%, and ALS + TLS = 4.56%). All models and datasets had similar accuracies in terms of bias (<2.0%), except for CB in ALS (−2.53%) and ALS + TLS (−2.86%), and SB in ALS + TLS data (−2.22%). These results demonstrate the usefulness of all three lidar-related methodologies and lidar modeling overall, along with lidar applicability in the estimation of crown structure and fuel attributes of longleaf pine forest ecosystems. Given that TLS measurements are less practical and more expensive, our comparison suggests that ALS measurements are still reasonable for many applications, and its usefulness is justified. This novel tree-level analysis and its respective results contribute to lidar-based planning of forest structure and fuel management

Rainfall and topographic position determine tree embolism resistance in AmazÃŽnia and Cerrado sites

Droughts are predicted to increase in both frequency and intensity by the end of the 21st century, but ecosystem response is not expected to be uniform across landscapes. Here we assess the importance of the hill-to-valley hydrologic gradient in shaping vegetation embolism resistance under different rainfall regimes using hydraulic functional traits. We demonstrate that rainfall and hydrology modulate together the embolism resistance of tree species in different sites and topographic positions. Although buffered by stable access to groundwater, valley plants are intrinsically more vulnerable to drought-induced embolism than those on hills. In all study sites, the variability in resistance to embolism is higher on hills than on valleys, suggesting that the diversity of strategies to cope with drought is more important for tree communities on hills. When comparing our results with previously published data across the tropics, we show greater variability at the local scale than previously reported. Our results reinforce the urgent need to extend sampling efforts across rainfall regimes and topographic positions to improve the characterization of ecosystem resistance to drought at finer spatial scales
