SUMMARY:
This study aims to analyze and compare the partition of plant diversity present in the upper, middle and lower strata of six agricultural mosaics in the Eastern Amazon (Guamá, Acará, Maçaranduba, Benfica, Palmares and Pacajá). In addition to comparing the gamma diversity between the mosaics, we sought to answer the following questions: 1) is the partition influenced by the specific aggregation of individuals? 2) is the partition influenced by the number of samples? 3) what is the contribution of land use types to beta and gamma diversity? 4) are the partition patterns similar between vegetation strata? In each mosaic an inventory was carried out in plots randomly distributed by different types of land uses, considering three vegetation strata: upper (individuals with DBH > 10cm), medium (individuals with DBH < 10 cm and height > 2 m) and lower (individuals with 2 m < height > 10 cm). The number of parcels by type of use differed between the tiles, as each type of use has different importance in each mosaic. Initial results indicate that the ranking of gamma diversity among mosaics changes according to strata. In all strata and all mosaics, alpha diversity makes a smaller contribution to gamma diversity; but the contribution of diversity within types of uses (Beta 1) and between types of uses (Beta 2) differ between mosaics and between strata.
