Título:  Functional trajectory for the assessment of ecological restoration success.

Conteúdo:  Ecological restoration aims to recover an ecosystem to a state before degradation. Comparison to reference ecosystems (old-growth forests) is a key component to define if restoration goals have been achieved ("success"). Nevertheless, it is still unknown how the functional composition of the initial community influences the trajectory of the ecosystem through time. Here, we evaluated restoration success based on the functional trajectory of six 20-year-old forest communities planted in the Brazilian Atlantic Forest with distinct combinations of ecological groups (pioneers, secondary, and climax). These six communities ranged their species predominance regarding resource-use strategies, potential size, and functional diversity. To evaluate restoration success, we compared the functional trajectory between the six planted communities after 20 years of secondary succession and calculated their trajectories toward or away from the reference ecosystem. We found that the initial composition influenced the functional trajectory of the communities undergoing restoration and it was a key element to their success. Only the community planted using the highest functional diversity (i.e. pioneer + early and late secondary + climax species) became functionally similar to the reference ecosystem 20 years after planting. The functional trajectories were mostly driven by the mortality of planted individuals than by the colonization of new species. The regeneration is still functionally simil... Mostrar Tudo

Título:  Hedge and central pruning in a high-density pecan orchard in southern Brazil.

Conteúdo:  This study aimed at evaluating the influence of two pruning methods, as well as absence of pruning, on vegetative and productive development and in the quality of pecan fruits in a high-density orchard. The experiment was conducted with the cultivar Melhorada in a commercial pecan orchard in municipality of Santa Rosa, Rio Grande do Sul state, Brazil. The study was carried out between July 2018 (dormancy phase of plants) and June 2020 (fruit ripening stage). In a randomized block design, the following treatments were applied: no pruning, hedge pruning and central pruning. Hedge pruning increased limb growth, while central pruning decreased the number of dry branches. Fruit production oscillated in the cycles. In the first, production was higher when central pruning was conducted. In the second cycle, it was higher in unpruned trees. Even though both pruning methods decreased the number of fruit with closed epicarps, they did not affect most variables of fruit quality. Therefore, results show that pruning methods promote vegetative development of pecan trees, reducing dry branches, but they are inconclusive regarding their production and have no significant effect on the main variables of their fruit quality. The evaluation and continuity of pruning for more cycles is important to obtain the most consistent results for indicating the best alternative for producers.
