The aim of this work was to characterize the spatial variability of the atributes of soil and plants in severely-eroded areas. The experimental plot had dimensions of 45 by 65 m, and was divided up into a grid with regular spacing of 5 m between points, making up a rectangle of 10 columns and 14 lines, totaling 140 points. The contents of macro and micronutrients were determined in the plants, plus dry mater and height of the Crotalaria juncea. The atributes of plants and soil thickness were distributed over the area in a well-defned spatial structure, with an adjustment of the spherical and Gaussian models, making an exception for calcium. Soil thickness demonstrated the locations with an accelerated process of erosion and displayed a clear spatial relationship with plant height and dry mater of the C. juncea and with the foliar macro and micronutrients.

A parcela experimental teve a dimensão de 45 por 65 m e foi dividida em uma malha com espaçamento regular de 5 m entre pontos, sendo um retângulo de 10 colunas e 14 linhas, totalizando 140 pontos. Foram determinados os teores de macro e micronutrientes nas plantas, matéria seca e altura da Crotalaria juncea L. Os atributos das plantas e a espessura do solo distribuem-se na área em estudo com uma estrutura espacial bem definida, com ajuste dos modelos esférico e gaussiano com exceção para o cálcio. A espessura do solo demonstrou os locais com o processo de erosão acelerado e apresentou forte relação espacial com a altura de planta e matéria seca da C. juncea e, com os macros e micronutrientes foliares.

The evaluation of diversity and genetic structure allows us to verify with precision the effect of evolutionary and anthropic processes on species. The objective of this research was to evaluate the divergence and the genetic structure of two natural populations of Dalbergia nigra, using molecular markers Inter Simple Sequence Repeats (ISSR). Leaf samples were collected from two populations, located in the National Forest of Pacotuba and the Private Natural Heritage Reserve of Cafundó. Eight ISSR primers were used, which resulted in 97 bands, with 68.04% of polymorphism. Based on the joint data, the values of 0.33 for the Nei index (H*) and 0.50 for the Shannon index (I*) indicated moderate to high genetic diversity, being influenced by the presence of genetically dissimilar individuals in the National Forest of Pacotuba. Most of the genetic divergence was intrapopulational (85.96%), with moderate differentiation between populations (ΦST = 0.1404). The estimated historical gene flow between the fragments was low (Nm = 3.21) when compared with results from other tree species, and the genetic structuring analysis separated the populations into two groups, corresponding to the two populations evaluated. The results indicate a small genetic share among populations, however, populations are becoming structured. The satisfactory levels of genetic diversity benefit the use of the trees as matrixes for programs of restoration and recovery of degraded areas, connectivity of landscapes, and sustainable use of forest resources.
