The project consists of studying the parasitic communities of fish species such as catfish and scales fish in the Amazon River system. The main points of analysis are the description of these parasitic communities, description of new species and checking whether the size of the host fish has an influence on the abundance of these parasites, their diversity, seasonal variation and their dispersion in the fish. The parasitic communities of different species of fish will be compared, as well as

Grassland intensification strategies such as fertilization and irrigation can be used to shorten the period required for recovery of paddocks under rotational management and thus to increase the productivity. In rotational stocking grazing, the definition of the resting and grazing periods of the paddocks, besides determining the total number of paddocks, exerts a great influence on the quantity and quality of the forage produced. The post-grazing residue, determined by the grazing period and th

For the economic exploitation of animal production in pastureland, it is essential to understand the morphophysiological responses of plants and animals to environment and management conditions, so that production can be efficient. This recommendation becomes more important in intensive pasture systems. In Brazil, especially in the Southeast, Midwest, North and Northeast regions, there is a predominance of tropical forage species, characterized by high dry matter production. However, problems su
