Description

This dataset provides information on total height (H) and stem diameter (D) of 65 tropical trees observed on the eastern of Maracá Island, a fluvial island integrated to the Maracá Ecological Station, state of Roraima, northern Brazilian Amazonia. The dataset was used to provide an allometric model representing the D:H relationship in an ecotone zone dominated by mosaics of ombrophilous and seasonal forests. In this way, linear and nonlinear regressions were tested to represent the better D:H relation. The best fitted model was Michaelis-Menten (see Barbosa et al. 2019 Allometric models to estimate tree height in northern Amazonian ecotone forests. Acta Amazonica, 49: 81-90; http://dx.doi.org/10.1590/1809-4392201801642). The dataset was supported by project “Crescimento e mortalidade de árvores em florestas ecotonais de Roraima: efeito das condicionantes ambientais e da variabilidade climática” (Proc. CNPq n. 403591/2016-3). The Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq - Brazil) also provided fellowships for R.I. Barbosa (CNPq 304204/2015-3) and P.M. Fearnside (CNPq 304020/2010-9). C.D.A. Villacorta and P.N. Ramirez-Narvaez were supported by postgraduate fellowships from the Organization of American States (OAS). L.C.S. Carvalho was supported by a fellowship from Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES/PNPD). Instituto Chico Mendes de Conservação da Biodiversidade (ICMBio) provided authorization for the study (SISBIO n. 52017).
