This paper analyzes the transition process of land use and land cover classes in the Tapajós area of endemism (AE) from 2004 to 2012. Using data from mapping carried out by the TerraClass project, and based on transition matrices, vulnerability, land usage and coverage were estimated. From the detailed transition matrix, we calculated net changes, gains, losses, persistence and, we can identify the vulnerability and the integrity of these classes. The Forest class was most sensitive to the changes and most fragile and susceptible to transitions. The Secondary Vegetation class presented high values of net persistence and the Class of Annual Agriculture presented high persistence. The Pasture class presented high susceptibility to loss of area to other classes. The Forest class of Tapajós AE was the most vulnerable to loss, change of use and coverage, with negative net persistence of 0.05. Secondary vegetation was characterized as a stable and growing class, with great potential for stabilization and permanence. Despite suffering from migration processes, Secondary Vegetation presented a positive growth of 1.63%, indicating the presence of successional sites and signs of recovery of deforested areas. The Annual Agriculture presented significant gains, mainly from the pasture areas, with 1.43% persistence, being configured as the class of greater integrity and tendency to extend its area. The conversion to pasture has been one of the main elements associated with deforestation in the region. The Pasture class was also considered a vulnerable class to the processes of change, reaching 0.15% of persistence.

Evaluations with sweet oranges are usually performed in several harvests and places to verify the differential behavior according to the environmental variations. This makes the selection by traditional statistical methodologies more and more difficult since they have limitations in the case of data unbalanced, common in citrus during the experimental phase due to the possibility of plot loss over the years. The objective of this work was to estimate the temporal stability and adaptability of sweet orange genotypes cultivated in eight crops under the edaphoclimatic conditions of Rio Branco, Acre. The experimental design used was in randomized blocks containing 55 genotypes and three replications. Four agronomic characteristics were evaluated during eight harvests. The genetic parameters were estimated using the REML/BLUP methodology. After detecting the presence of significant interaction between genotypes and environments, stability and adaptability analyzes were conducted by the methods of the harmonic mean of the genotypic values (HMGV), the relative performance of the genetic values (RPGV) and the harmonic mean of the relative performance of the genotypic values (HMRPGV). The HMRPGV can be used to select stable, adapted and productive sweet orange genotypes. The number 48, 19, 5, 14, 2, 47 and 37 sweet orange genotypes can be selected for cultivation in an environment similar to the one studied, as they simultaneously present high stability, adaptability and productivity. |
