          Abstract

          Visando a suprir a lacuna do conhecimento existente sobre a estimação precisa do potencial de produção madeireira de sistemas de restauração florestal, com o presente trabalho, objetivou-se modelar as relações alométricas (hipsométricas e volumétricas) de nove espécies comuns a modelos alternativos de restauração da floresta estacional semidecidual. Os modelos se ajustaram bem aos dados coletados e a análise de resíduos indicou distribuição satisfatória, tanto para os modelos hipsométricos como volumétricos. O modelo hipsométricos de Stoeffels e o modelo volumétrico de Schumacher-Hall foram os mais flexíveis, ajustando melhor para várias espécies. Essas equações obtidas serão usadas em futuros estudos de manejo e conservação de áreas em restauração.

          Translated abstract

          Aiming to overcome the lack of knowledge about precise estimation of wood production potential of forest restoration systems, the objective of this study is modeling allometric relationships of nine tree species in alternative models of seasonal semideciduous forest restoration. The models fitted well to the data with satisfactory distribution of the residuals. The height-diameter relationship was best modeled by the Stoeffles model and the volume equations had the best fit with the Schumacher-Hall model, for many species. The equations obtained will be used in future studies of management and conservation of these plantations.

              Alternatives to statistical hypothesis testing in ecology: a guide to self teaching.

              Statistical methods emphasizing formal hypothesis testing have dominated the analyses used by ecologists to gain insight from data. Here, we review alternatives to hypothesis testing including techniques for parameter estimation and model selection using likelihood and Bayesian techniques. These methods emphasize evaluation of weight of evidence for multiple hypotheses, multimodel inference, and use of prior information in analysis. We provide a tutorial for maximum likelihood estimation of model parameters and model selection using information theoretics, including a brief treatment of procedures for model comparison, model averaging, and use of data from multiple sources. We discuss the advantages of likelihood estimation, Bayesian analysis, and meta-analysis as ways to accumulate understanding across multiple studies. These statistical methods hold promise for new insight in ecology by encouraging thoughtful model building as part of inquiry, providing a unified framework for the empirical analysis of theoretical models, and by facilitating the formal accumulation of evidence bearing on fundamental questions.
