The major determinants of productivity in Eucalyptus plantations include the site productive capacity, local environmental uniformity, and the tree genetics, which impact their growth potential and competitiveness. While these factors have received a lot of attention individually, less attention has been given to the relative importance of these factors and the interactions between them. We examined these factors and their interactions using eight experiments located along a gradient in site productivity, consisting of 54 clonal genotypes (Eucalyptus urophylla × E. grandis hybrids) at two plant spacings (3 × 3.33 and 3 × 2 m). Stand productivity was quantified as the mean annual increment at age 6 years (m3 ha?1 year?1). Site productive capacity was represented using a site index based on mean dominant height at age 6 years. Environmental uniformity was calculated from within-plot variability in growth of very young stands using residual spatial autocorrelation. The competitive ability of a given phenotype was calculated as the percent loss in potential growth due to neighbor competition. Productivity increased with all variables but site quality had the greatest effect, followed by environmental uniformity and then competitive ability, with corresponding changes in productivity of about 30, 20 and 10 m3 ha?1 year?1, respectively, across the range of the given variable. With higher environmental heterogeneity, competition among genotypes increased, especially at dense spacing, showing that in such situations, highly competitive genotypes may display productivities similar to the less competitive genotypes in uniform environments. Experimental plots distributed across site quality and uniformity gradients provide opportunity for greater genetic differentiation than plots covering more homogeneous environments, reinforcing the recommendation of establishing genetic tests in locations with extreme site qualities. Our work suggests that the G × E interaction is linked to site quality and, to a lesser degree, to the local environmental uniformity. This work shows the value of adopting environmental gradient-based approaches in tree genetic testing and clone recommendation as a way to more accurately match genotypes to specific sites.

The Brazilian Government has been promoting studies on the zoning and demarcation of aquaculture parks dedicated to the production of fish in net-cages in the large public reservoirs of the country. The methodology employed for the zoning of these aquaculture parks consists of the execution in three consecutive stages of multidisciplinary evaluations for their social, environmental and economical characterization (global, regional and local). The purpose of the studies involves the generation of thematic maps and scenarios of environmental models that facilitate the process of understanding the regional peculiarities and taking the decisions to identify the most appropriate areas for the installation of the aquaculture parks. The application of this instrument for zoning the reservoirs will assist a more effective planning of investments and efforts, both by the government and by private initiative, in the aquaculture activity. With the implantation of aquaculture parks along the lines of an ecosystemic aquaculture, Brazil has the potential to become one of the largest producers of fish in net-cages in the world. |
