Item Diversidade de invertebrados do solo em sistema agroflorestal e diferentes ambientes sucessionais em floresta ombrófila densa(2024-02-16) Souza, João Matheus Ferreira de; Gonçalves, Maria da Penha Moreira; Almeida, Débora de Melo; http://lattes.cnpq.br/9795066247076929; http://lattes.cnpq.br/0539509819672370; http://lattes.cnpq.br/7784879810259175Studies on soil fertility and soil fauna diversity in agroforestry systems are of fundamental importance to prove the efficiency of these sustainable production models associated with the recovery of degraded areas. This work aims to evaluate correlations between soil fauna diversity and soil fertility in an agroforestry system and areas of native forest at initial and intermediate stages of forest succession. The study was conducted in the campus area of the Federal Rural University of Pernambuco, located in the Metropolitan Region of Recife, Pernambuco. Three sites with different land use histories were used: an area at an intermediate stage of forest succession (A1), a 3-year-old agroforestry system (A2), and an area at an initial stage of forest succession (A3). Pitfall traps were used to capture the soil invertebrate community. The captured organisms were identified, classified into taxa, and subsequently sent for analysis. Soil collection covered the 0-20 cm and 20-40 cm layers in each study area. The samples underwent chemical analysis. Data on soil meso- and macrofauna were used to calculate abundance, relative frequency, richness, Pielou's evenness indices, Shannon's diversity, and Simpson's diversity. Hill's true diversity components (qD) were estimated for each environment. Data analysis also included exploratory analysis with NMDS, permutational multivariate analysis of variance (PERMANOVA), Pearson correlation matrix, agglomerative hierarchical clustering analysis (HAC), principal component analysis (PCA), and Canonical Correlation Analysis (CCA). A total of 2,232 individuals distributed in 18 taxonomic groups were identified. Overall, regardless of land use, the most representative groups were Hymenoptera: Formicidae (37.46%), Acarina (21.10%), Collembola (15.86%), and Diptera (9.68%). Together, these groups represented 84% of the individuals collected in this study. The agroforestry area showed greater richness, the area of initial forest succession showed greater abundance in groups, and the area at an intermediate stage of succession showed greater diversity. Although the agroforestry area had greater richness, the estimated diversity was lower compared to the area of initial forest succession. Soil chemical analysis showed differences between the areas, influencing fauna distribution. Similarity in fauna composition was observed between the agroforestry area and the initial forest succession, highlighting the influence of soil chemical attributes on soil fauna. It is concluded that the study of soil fauna has the potential to be used as an indicator of soil quality, as it is sensitive to environmental interference.Item Zoneamento agroclimático para plantio de Eucalyptus urophylla na Zona da Mata de Pernambuco(2024-02-19) Silva, Carlos Antônio Campelo Cavalcanti; Silva, Emanuel Araújo; Almeida, Débora de Melo; http://lattes.cnpq.br/2765651276275384; http://lattes.cnpq.br/1534900496128952The state of Pernambuco, encompassing the biomes of the Atlantic Forest and Caatinga, faces challenges of degradation, especially in the Atlantic Forest, extensive sugarcane cultivation has resulted in forest fragmentation of biome, with impoverished and abandoned areas. The study suggests reestablishing the use of these degraded areas considering market demand, with the main objective of conducting an agroclimatic zoning of areas suitable for eucalyptus plantation in the Zona da Mata of Pernambuco. To achieve this, data on average air temperature and precipitation were collected from four meteorological stations distributed in the region. Using these data, monthly climatic water balance was calculated following the method proposed by Thornthwaite and Mather (1955). Subsequently, the data were processed and mapped using a Geographic Information System (GIS) environment using QGIS 3.16 software. The agroclimatic zoning was elaborated considering the climatic requirements of the Eucalyptus urophylla species, highlighting areas with thermal and water conditions suitable for cultivation. The results showed that approximately 28.95% of the analyzed territory in the Zona da Mata is suitable for the development of the species, concentrating in 16 municipalities surrounding the Metropolitan Region of Recife. This potential area totals 2428 km². On the other hand, approximately 71.05% of the studied area was considered unsuitable due to identified levels of water deficit. These results can contribute to land use planning, promoting more sustainable and effective cultivation practices in the region.
