The Eucalyptus dunnii Maiden is an outstanding species for growth and wood quality traits. However, important wood quality traits for pulp and paper production are disregarded in tree breeding. Thus, the present study aimed to estimate the genetic parameters of growth and wood quality traits and establish selection criteria to increase pulp production in E. dunnii clones in different environments. The clonal test of E. dunnii was established in a randomized complete block design with a single-tree-plot in three environments. Growth values were obtained from 3.5-year-old trees. Wood quality values were measured by near-infrared spectroscopy. The phenotype index mean annual pulp increment was calculated using the values of mean annual increment, basic wood density, and pulp yield. A mixed linear model via REML/BLUP was used to obtain the genetic parameters and the rank of genotypic values considering several environments. Results revealed genetic variance for wood quality traits in E. dunnii. Klason Lignin presented high broad-sense heritability; basic wood density, pulp yield, mean annual pulp increment, and mean annual volume increment had moderate broad-sense heritability; and total extractives and diameter at breast height showed low broad-sense heritability. All traits presented high to very high selective accuracy. Simple clones x environments interactions were observed for the tested environments. An elite clone of E. dunnii were better than the commercial control clone for annual pulp increment mean. Therefore, the selection based on growth and wood quality traits is essential for pulp and paper sector.

Abstract: Landscape is an ecological category represented by a complex system formed by interactions between society and nature. Spatial patterns of different land uses present in a landscape reveal past and present processes responsible for its dynamics and organisation. Measuring the complexity of these patterns (in the sense of their spatial heterogeneity) allows us to evaluate the integrity and resilience of these complex environmental systems. Here, we show how landscape metrics based on information entropy can be applied to evaluate the complexity (in the sense of spatial heterogeneity) of patches patterns, as well as their transition zones, present in a Cerrado conservation area and its surroundings, located in south-eastern Brazil. The analysis in this study aimed to elucidate how changes in land use and the consequent fragmentation affect the complexity of the landscape. The scripts CompPlex HeROI and CompPlex Janus were created to allow calculation of information entropy (He), variability (He/Hmax), and López-Ruiz, Mancini, and Calbet (LMC) and Shiner, Davison, and Landsberg (SDL) measures. CompPlex HeROI enabled the calculation of these measures for different regions of interest (ROIs) selected in a satellite image of the study area, followed by comparison of the complexity of their patterns, in addition to enabling the generation of complexity signatures for each ROI. CompPlex Janus made it possible to spatialise the results for these four measures in landscape complexity maps. As expected, both for the complexity patterns evaluated by CompPlex HeROI and the complexity maps generated by CompPlex Janus, the areas with vegetation located in a region of intermediate spatial heterogeneity had lower values for the He and He/Hmax measures and higher values for the LMC and SDL measurements. So, these landscape metrics were able to capture the behaviour of the patterns of different types of land use present in the study area, bringing together uses linked to vegetation with increased canopy coverage and differentiating them from urban areas and transition areas that mix different uses. Thus, the algorithms implemented in these scripts were demonstrated to be robust and capable of measuring the variability in information levels from the landscape, not only in terms of spatial datasets but also spectrally. The automation of measurement calculations, owing to informational entropy provided by these scripts, allows a quick assessment of the complexity of patterns present in a landscape, and thus, generates indicators of landscape integrity and resilience.
