Agrupamento ecológico e funcional de espécies florestais da Amazônia Central

Abstract

Development will be the of the present work they had been used given of 56 permanent parcels, with area of one hectare each (100 x 100), subdivided in subparcelas of 10 x 10, installed in two seek areas: Company A thousand Lumber Itacoatiara Ltda., city of Itacoatiara, and Experimental Station of the Farming District of the Suframa - OF the pertaining a Embrapa Amazônia Occidental person, city of Manaus, both in the State of Amazon. The research had as objective main to study the dynamics of growth of the forest for ecological groupings being used you analyze multivaried statisticians (analysis of Cluster and Discriminante). In these sub-parcels all the individuals with diameter the height of the chest, DAP ≥ 10 cm (OF) and DAP ≥ 15 (A thousand Lumber) had been identified by the vulgar and scientific name and had had the measured DAP, being three measurements in compartment B (1996, 1998, and 2001) and in the one OF (2005, 2007, 2010). e two in compartment C (1997 and 2001) and D (1998 and 2001). The process involved three periods of training: (1) analysis of Cluster to make the grouping of the species most populous, for this process had been used the 0 variable: (Annual Periodic Increment in diameter - average IPADAP in High, Measured and Decrease competition and percentile 95% of the distribution of cumulative frequency of the DAPs) and the hierarchic method Ward; (2) Discriminante analysis, to place the species less populous to the formed groups, using the same 0 variable: (Annual Periodic Increment in diameter - average IPADAP in High, Measured and Decrease competition and percentile 95% of the distribution of cumulative frequency of the DAPs) and the method of Fisher; (3) subjective period of training, used to place the species with few individuals to the formed groups. The application of analyzes of grouping using the method of Ward, resulted in the formation of ten groups of high species with crescimentos of similars etween individuals of group and the same low similarity between groups. The classification of the groups better allowed knowledge of the species that possesss similarity in the annual average periodic increment. From the displayed one one concludes that species climax possesss the slow annual average increment on average periodic, arriving at a standard of diameter of up to 87,8 cm, species of average canopy on average possess the growth slowest of what the species climax, pioneering species of long life possesss fast growth, that can diminish throughout probable the twenty years of life of these species
