“…Elevation is applied as a proxy for temperature gradient (Rutherford, Bebi, 2008), to distinguish flood areas (Schneider and Pontius, 2001), but also to determine the vertical zonality of soils (Florinsky, Kuryakova, 1996). Slope is a typical driver utilized to represent cultivation costs in the area (Gellrich et al, 2007).…”

“…É importante considerar que as caracterís-ticas da cobertura vegetal dependem de outras variáveis, além das causadas pelo substrato geológico e pelo solo. Florinsky & Kuryakova (1996) e Rowan et al (2000) demonstram como a topografia intervém nas coberturas vegetais de forma independente ao substrato rochoso, ao clima e à pedogênese. Já Bognar et al(1999) expõem que apenas a variação no horário da iluminação solar direta (matutina, vespertina) impõe severas diferenças nas coberturas vegetais, em função de variações diurnas da interação da radiação eletromagnética com os fitocromos, constituindo a orientação da vertente uma variável independente em relação à variável dos solos.…”

Resumo A geobotânica, mesmo sendo possivelmente o primeiro método indireto de prospecção de minérios metálicos, não vem sendo utilizada pela comunidade, sobretudo em florestas tropicais. O principal motivo pode ser a falta de geólogos com conhecimentos de botânica. Há autores que consideram serem as florestas de climas frios e temperados mais adaptadas à técnica pela mais pobre biodiversidade, solos menos espessos e maior interação da vegetação com as rochas encaixantes, deixando as amplas florestas tropicais sem tal abordagem. O objetivo deste trabalho é demonstrar a intensa influência de um processo mineralizante -alteração hidrotermal clorítica -em segmento de Mata Atlântica. São apresentados os resultados de estudo botânico de dois segmentos de floresta atlântica montana crescidos sobre rochas da Formação Morro da Pedra Preta, Grupo Serra do Itaberaba: um sobre rochas meta-básicas e outro sobre rochas metabásicas e metaintermediárias afetadas por um evento de alteração clorítica ao qual estão geneticamente associadas mineralizações de ouro. Observe-se que as metaintermediárias têm composições químicas muito próximas às das rochas básicas. Os dados obtidos em campo evidenciam importante dissimilaridade fisionômica e florística entre as coberturas vegetais, as quais podem ser atribuídas apenas à presença de alteração hidrotermal nas rochas do substrato de uma das parcelas, pois estas são vizinhas e têm iguais parâmetros de altitude, direção e inclinação de encosta e história de sucessão florística. Com este dado, a geobotânica, particularmente associada ao sensoriamento remoto óptico, assunto não tratado neste trabalho, deve ter seu uso seriamente considerado na prospecção mineral e no mapeamento geológico básico em outros biomas com florestas mais preservadas, como na Amazônia. Palavras-chave: geobotânica, alteração hidrotermal, comunidades florestais, Mata AtlânticaAbstract Forest communities as geobotanical indicators: the case of the auriferous mineralization of Serra do Itaberaba Group, Guarulhos, São Paulo. The geobotany was probably the first indirect method of metallic ore exploration. However it is rarely used by the community, especially in tropical forests, probably because of the difficulties to have a geologist with high botanical knowledge. Some authors believe that cold and temperate forests are more adapted to the technique due to its poorer biodiversity, thinner soils and greater vegetation interaction with the bedrock. The objective of this work is to demonstrate the intense influence of a mineralization process -chloritic hydrothermal alteration -on the Mata Atlantic rain forest. We present the results of a botanical study of two segments of mountainous Atlantic forest grown on soils over rocks of Morro da Pedra Preta Formation, Serra do Itaberaba Group: one over metabasic rocks and another over metabasic and meta-intermediate rocks submitted to chloritic alteration, which is genetically associated to gold mineralizations. The meta-intermediate rocks chemical compositions are very near to th...

“…It has been argued that one of the most important factors for the development of vegetation cover over any land surface is relief (Florinsky & Kuryakova, 1996). Moreover, literature (Hengl & MacMillan, 2009) has shown that information on relief is often sufficient to produce reliable vegetation map, if other factors are held constant.…”

“…Hence, land surface parameters (elevation, aspect and slope, etc.) are commonly used in vegetation mapping (Florinsky & Kuryakova, 1996). These parameters could be combined to produce land surface units which are then related to vegetation cover.…”

Digital elevation models (DEMs) have shown much potential for use in the extraction of land surface parameters and analysis of the relationship between land surface units and vegetation cover. However, there is lack of studies on the use of SRTM-3 DEM in vegetation studies of mountainous regions. This study is therefore an attempt to relate land surface parameters to vegetation cover in the Obudu mountain region using SRTM-3 DEM and Landsat data. Geomorphometric classification of the land surface was done using an unsupervised ISOCLUST algorithm while vegetation cover classification was done using the supervised approach based on the Maximum Likelihood algorithm. The resultant land surface units and vegetation cover maps were then related using grid-based statistic within the geographic information systems. The overall measure of difference between the two maps yielded a chi-square (d.f. = 24) = 1.9154, p > 0.05. This implies that there is no significant difference between the land surface units and the vegetation cover in the study area. This findings support the use of SRTM-3 for land surface and vegetation mapping where there is no higher quality data, or the cost of obtaining one is inhibitive; a situation that is faced by many developing economies like Nigeria. However, this results should be interpreted and used within the context of the uncertainty that is contained in the SRTM-3 DEM.
