Deforestation of native ecosystems causes microclimatic changes at the edge of the remaining forest fragments. This ?edge effect? can modify soil attributes, although there is little information on this. Thus, this study aimed to evaluate the edge effect on soil microclimate conditions, chemical, microbiological and arthropod community attributes and their relationship with litter attributes in a fragment of Semideciduous Seasonal Forest, in Piraí, RJ, Brazil. In the middle of the dry period (June/2019), four ranges of distances parallel to each other were established from the edge of the forest fragment: Edge: 0 m; Range 1: 50 m; Range 2: 100 m; and Interior: 160 m. In each range, five sampling points were established, spaced 10 m apart, where soil samples were collected in the 0?5 cm layer and litter samples. This material was employed to determine microclimatic, chemical and biological (arthropod community and microbiological attributes) attributes of the soil; and litter stock, concentration and content of nutrients. Forest fragmentation altered litter attributes and consequently soil moisture and nutrients, the communities? attributes of soil arthropods and microorganisms. These modifications in such aspects of nutrient cycling could compromise the forest functioning and the conservation of local biodiversity. Thus, we suggested the planting of non-pioneer native tree species in distances closest to the forest edge and installing of ecological corridors to connect the forest fragment to other remnants, in order to diminish the edge effect.

Contamination with trace elements is characterized by an abiotic stress that represents a limiting factor in agricultural production. Considering that cadmium (Cd) and Zinc (Zn) are physically and chemically similar, they can interact with the environment, causing antagonistic or synergistic effects. In this sense, physiological mechanisms to exclude, detoxify or compartmentalize the excess of those trace elements is crucial for the survival of the plants under conditions of high concentrations of these elements. In order to understand the responses of the species sensible to the presence of Cd and Zn, this study aimed to access the behavior of maize plants (Zea mays L.) cultivated in Cambisoils and Latosol with growing concentrations of Cd/Zn in a 21 days period. Growth and biochemical analyzes were performed such as antioxidant enzyme SOD, CAT and APX activity, hydrogen peroxide and lipid peroxidation. The data obtained evidenced the specific behavior of maize plants grown in Cambisoils compared to Latosol, showing a superior activity of all the enzymes analyzed, and also a lower content of hydrogen peroxide and lipid peroxidation. The interaction between both the elements resulted in a synergistic effect, negatively influencing all the analyzed parameters. |
