Classificador de máxima verossimilhança aplicado à identificação de espécies nativas na Floresta Amazônica. Repositório Alice
MORAS FILHO, L. O.; FIGUEIREDO, E. O.; ISAAC JÚNIOR, M. A.; BARROS, V. C. C. de; HOTT, M. C.; BORGES, L. A. C..
Among a variety of digital classification methods based on remote sensing images, the Maximum Likelihood (ML) is widely used in environmental studies, mainly for land cover and vegetation analysis. This study aimed to evaluate the effectiveness of supervised classification by ML technique in a forest management area of dense ombrophilous forest, using one RapidEye image. With this purpose, it was conducted the census of species over 30 cm in diameter at breast height and calculated the Cover Value Index (CVI), and selected the 20 species with the highest CVI as a parameter for classification in a Geographic Information System. 13 of the 20 species selected in the study area were not identified by the classification method, and among the seven identified...

The status of Cecropia (Urticaceae) introductions in Malesia: addressing the confusion Naturalis
Conn, B.J.; Hadiah, J.T.; Webber, B.L..
As part of the great global movement of plants in the 18th and 19th centuries, many valuable and commercial plants were sent from the Neotropics to Europe as seeds or as live specimens. Cecropia (Urticaceae) was in cultivation in England in 1789, yet species delimitation was not well-understood until much later, long after subsequent introductions to other tropical regions where alien populations are now invasive. The earliest record of Cecropia being cultivated in Malesia is based on material of C. peltata thought to have been sent from the Royal Botanic Gardens Kew to ’s Lands Plantentuin (Buitenzorg) in Jawa, Indonesia, sometime between 1862 and early 1868. In 1902, C. peltata was first cultivated in the botanical gardens of Singapore and introduced to...
