Spittlebug, Mahanarva spectabilis (Hemiptera: Cercopidae) is capable to cause drastic losses in production and quality of pastures established with grasses. Currently, the use a grass resistant cultivar, to be obtained by means of constitutive antibiosis, is the best spittlebug controlling method. However, the time required for releasing a cultivar after detecting a spittlebug-resistant strain is relatively long. Allied to this, one should take into consideration that the adaptations of

The goal is to assess the economic and ecological effectiveness of different models of forest restoration of degraded areas through the induction of secondary ecological succession, by natural regeneration, planting of seedlings, and the direct sowing of native and exotic tree species to compose the Legal Reserve.

The general objective of this project was to identify microbial strains that produce enzymes capable of degrading fibers or hydrolyzing secondary anti-nutritional compounds, aiming to identify microbial isolates (rumen bacteria or fungi) with fibrolytic capacity or tolerant to anti-nutritional factors, as well as to expeditiously isolate and characterize fibrolytic enzymes. It was also the objective of this project that the use of laboratory procedures would serve to train undergraduate and grad

Agricultural systems basically depend on ecological processes and services provided by ecosystems. These ecological processes and services, called ecosystem services or environmental services, relate to the conditions and processes through which ecosystems sustain human life by supplying provisions (food, timber, fiber and fuel production), regulation (of water, of climate, protection against droughts, flooding, storms, spread of diseases and soil degradation, waste purification), support (hydro
