SUMMARY:

In the Amazon, forest management has gained increasing prominence due to its contribution as a source of income for local communities and reducing damage to the environment. In order to manage a species, research is needed into its autoecology. The species Minquartia guianensis Aubl. is popularly known as acariquara, belongs to the Coulaceae family, occurs throughout the Amazon region and has potential for timber use. However, its exploitation is largely carried out illegally, as few trees reach the cutting diameter suggested in Brazilian regulations (DBH ≥ 50 cm). For this reason, research that defines indicators based on the species' autoecology is essential in order to contribute to the development of specific regulations for the management of M. guianensis. Against this backdrop, the aim of this study is to answer the following question: Does logging affect tree dynamics over 29 years of monitoring? To address this question, we used data from 36 0.25-hectare plots (50 m x 50 m) installed in the Tapajós National Forest on 108 ha of terra firme forest. In the permanent plots, trees with DBH ≥ 5 cm were measured in 1981, 1983, 1987, 1989, 1995, 2008 and 2012. To assess the dynamics of M. guianensis, estimates were made of the annual periodic increment in diameter, tree mortality and recruitment rates, as well as an analysis of the species' population structure. The structure of the thesis was divided into two parts. Part I contains two chapters reviewing the scientific literature. The first chapter contains a review of the use of ecological parameters as mechanisms for determining the cutting diameter and the second provides information on the ecology, silviculture and use of M. guianensis. In this work, M. guianensis has a high economic value with potential for use, especially in the smaller diameter classes, and if managed it has a market differential. Part II contains a proposal for a management system for the species. In Chapter III, the aim was to evaluate the structure and dynamics of Minquartia guianensis before and after timber harvesting and thinning of non-commercial species in an area of terra firme forest in the Tapajós National Forest, in the municipality of Belterra, with a view to subsidizing the establishment of forest management for the species. From this perspective, the research has a fundamental role to play, as the results obtained can generate criteria and indicators that enable the inclusion of M. guianensis wood through the creation of a specific standard. The results can help to support management guidelines for the species, guarantee its conservation and make it possible to supply this forest product, M. guianensis wood, to the local market. It is considered that the legal use of forest products guarantees social dignity and the construction of sustainability in the use of forest resources, especially in the quality of life of rural communities and family farmers who survive on extractivism, as well as proposing alternatives for community management in areas of the Eastern Amazon.
