Tree growth and survival differ strongly between canopy trees (those directly exposed to overhead light), and understory trees. However, the structural complexity of many tropical forests makes it difficult to determine canopy positions. The integrat

Digital Approach for Measuring Tree Diameters in the Amazon Forest
Autor: Carlos Henrique Souza Celes, Raquel Fernandes de Araujo, Fabiano Emmert, Adriano José Nogueira Lima, Moacir Alberto Assis Campos
Publikováno v: Floresta e Ambiente, Vol 26, Iss 1 (2019)
ABSTRACT Buttresses and other natural structures modify the shape of stems in Amazonia and change the diameter at breast height (DBH) measured at 1.3 m at ground level. The lack of adequate measurement techniques affects negatively forest dynamics an

ESTIMATIVA DE BIOMASSA EM UMA FLORESTA TROPICAL NO MUNICÍPIO DE MAUÉS - AM, BRASIL
Autor: Carlos Henrique Souza Celes, Yosio Edemir Shimabukuro, Moacir Alberto Assis Campos, Niro Higuchi
Publikováno v: Revista Brasileira de Cartografia, Vol 65, Iss 3 (2013)
O sensoriamento remoto (SR), sistema de informação geográfica (SIG) e sistema de posicionamento global (GPS) são importantes ferramentas para as diversas etapas de inventários florestais, inclusive para as estimativas de biomassa. O objetivo des

Gap geometry, seasonality and associated losses of biomass – combining UAV imagery and field data from a Central Amazon forest
Autor: Adriana Simonetti, Raquel Fernandes Araujo, Carlos Henrique Souza Celes, Flávia Ranara da Silva e Silva, Joaquim dos Santos, Niro Higuchi, Susan Trumbore, Daniel Magnabosco Marra
Publikováno v: Biogeosciences Discussions
Understanding mechanisms of tree mortality and geometric patterns of canopy gaps is relevant for robust estimates of carbon stocks and balance in tropical forests, and for assessing how they are responding to climate change. We combined monthly RGB i

Strong temporal variation in treefall and branchfall rates in a tropical forest is related to extreme rainfall: results from 5 years of monthly drone data for a 50 ha plot
Autor: Raquel Fernandes Araujo, Samuel Grubinger, Carlos Henrique Souza Celes, Robinson I. Negrón-Juárez, Milton Garcia, Jonathan P. Dandois, Helene C. Muller-Landau
Publikováno v: Biogeosciences, Vol 18, Pp 6517-6531 (2021)
A mechanistic understanding of how tropical-tree mortality responds to climate variation is urgently needed to predict how tropical-forest carbon pools will respond to anthropogenic global change, which is altering the frequency and intensity of stor
