“…Due to a lack of liana and understory species data recorded for the forest plots, we cannot say from which group of plants (herb or liana) the Asteraceae phytoliths belong. Slightly elevated counts of Mendoncia show that lianas are more common in this forest and they may be a secondary growth component of this disturbed type of forest ( (Balée, 1990)). ISTs were also very abundant in a few of the C-fraction samples.…”

Abstract:Accurate archaeological and palaeoenvironmental reconstructions using phytoliths relies on the study of modern reference material. In eastern Acre, Brazil, we examined whether the five most common forest types present today were able to be differentiated by their soil phytolith assemblages, and thus provide analogues with which to compare palaeoecological assemblages from pre-Columbian earthwork sites in the region. Surface soils and vegetation from dense humid evergreen forest, dense humid evergreen forest with high palm abundance, palm forest, bamboo forest and fluvial forest were sampled and their phytoliths analysed. Relative phytolith frequencies were statistically compared using Principal Components Analyses (PCAs). We found the major differences in species composition to be wellrepresented by the phytolith assemblages as all forest types, apart from the two subtypes of dense humid evergreen forest, could be differentiated. Larger phytoliths from the sand fraction were found to be more ecologically diagnostic than those from the silt fraction. The surface soil phytolith assemblages we analysed can therefore be used as analogues to improve the accuracy of archaeological and palaeoecological reconstructions in the region.

“…Central parts of planalto stretches, far away from the scarps, can have com pact subsoils; in these cases the veg etative cover is a liana-rich open-canopy forest, or even pure liana forest or "cipoal" (Sombroek, 1966, p. 194-196). The latter vegetation type predominates on the left bank of the lower Xingu and may be the enduring result of past Amer-indian occupation (Balée & Campbell, 1989). …”

Amazon landforms and soils in relation to biological diversity

-Thirteen main landform units are distinguished for the whole of the forested planalto, and in the areas of relict valleys, in view of the prolonged geomorphological stability Key-words: Amazon, major landforms, tropical soils, floristic biodiversity. Paisagens Maiores da Amazônia e seus Solos em Relação com a BiodiversidadeRESUMO -Foram distinguidas treze unidades de paisagens maiores, em toda região Amazônica florestada, cada unidade com padrão de solos e estrutura de cobertura vegetal específica. Estas unidades de paisagem-solos-vegetação foram delineadas num mapa geral da região e ilustradas por um corte transversal esquemático. A diversidade florística, do tipo gamma, deve ser a mais alta no complexo paisagístico da Selva Alta, bordeando a Cordilheira Andina; nas terras firmes colinosas dos escudos cristalinos; no complexo de inselbergs, e no variante eutrico das terras firmes sedimentárias ocidentais. Estima-se que o endemismo seja mais alto nas planícies arenosas, e em partes dos complexos de chapadões e de inselbergs. Especiação, ligada com o conceito de refúgios florestais, é provavelmente mais alta nos chapadões de areniscos antigos, nas extensões do planalto Amazônico, e nas áreas de vales relictos, considerando a estabilidade geomorfológica prolongada destas unidades.Palavras-chave: Amazônia, unidades de paisagem; solos tropicais; biodiversidade florística 1 Ά preliminar version of this text appeared in ISRIC Annual Report over 1990, Wageningen, the Netherlands.

“…Indeed, palm-dominated forest patches in well-drained areas of Amazonia of a few to several hectares, seem to be related to past human disturbance (Ballée 1989, Ballée and Cambell 1990, Anderson et al 1991, Kahn and Granville 1992. Numerous monodominant forest enclaves of 2-3 ha of Attalea phalerata (babassu) in the Brazilian State of Maranhão are often associated with old human settlement sites (Ballée 1984).…”

This study examines aspects of the stem density and growth of two large arborescent palms Attalea maripa and Astrocaryum aculeatum and discusses their implication for the palm trees distribution in Amazonia. Stem density and growth were investigated through both laboratory measurements and field estimates of growth rates. The densities of stem samples collected within one individual of each studied species were very distinct. The samples of A. maripa stem were more homogeneous in density than those of A. aculeatum, both from the internal to the external, and from the lower to the upper parts of the stem. Field estimates of stem growth rates revealed that A. maripa growth is also more constant through development in height. Short A. aculeatum palms had faster growth rates than A. maripa, as they get taller, stem growth rates are reduced and approach A. maripa rates. The implications for arborescent palms distribution across Amazonian forests are discussed. Key words: Amazonia, Astrocaryum aculeatum, Attalea maripa, Distribution, Palms, Stem density ResumoEste estudo examina aspectos da densidade do caule e crescimento de duas palmeiras arborescentes de grande porte Attalea maripa e Astrocaryum aculeatum e discute suas implicações para a distribuição de palmeiras arborescentes na Amazônia. Densidade dos caules e crescimento foram investigados através de uma combinação de medidas de laboratório e estimativas de campo de taxas de crescimento. As densidades de amostras do caule coletadas de um indivíduo de cada espécie foram muito distintas. As amostras do caulde de A. maripa foram mais homogêneas em densidade que aquelas de A. aculeatum, tanto das partes internas para externas, como inferiores para superiores dos caules. Estimativas de campo de crescimento do caule revelaram que o crescimento de A. maripa também é mais constante ao longo do desenvolvimento. Palmeiras A. aculeatum baixas tiveram crescimento mais rápido que A. maripa, palmeiras mais altas têm seu crescimento reduzido a níveis semelhantes ao de A. maripa. São discutidas as implicações para a distribuição de palmeiras na Amazônia. Palavras-chave:
