Morphology and allometry of juvenile açaí palms under cultivation conditions in Central Amazonia. Author(s): DELGADO, J. P. M.; CUNHA, R. N. V. da; MORAIS, R. R. de; LOPES, M. T. G.; FERREYRA RAMOS, S. L.; RODRIGUES, M. do R. L.; MEDEIROS, N. M. C. de; MENESES, C. H. S. G.; SILVA, E. B. da; LOPES, R. Two Amazonian species of açaí palm trees (Euterpe oleracea and Euterpe precatoria) are exploited in the commercial production of açaí pulp or juice. While E. oleracea benefits from developed cultivati... ... Repository: BDPA Publication year: 2024
Seeing the forest beyond the trees. Author(s): SAATCHI, S.; MASCARO, J.; XU, L.; KELLER, M.; YANG, Y.; DUFFY, P.; ESPÍRITO-SANTO, F.; BACCINI, A.; CHAMBERS, J.; SCHIMEL, D. In a recent paper (Mitchard et al. 2014, Global Ecology and Biogeography, 23, 935?946) a new map of forest biomass based on a geostatistical model of field data for the Amazon (and surrounding forests... ...

Mixed-effects height prediction model for Juniperus procera trees from a Dry Afromontane Forest in Ethiopia. Author(s): TESHOME, M.; BRAZ, E. M.; TORRES, C. M. M. E.; RAPTIS, D. I.; MATTOS, P. P. de; TEMESGEN, H.; RUBIO-CAMACHO, E. A.; SILESHI, G. W. Tree height is a crucial variable in forestry science. In the current study, an accurate height prediction model for Juniperus procera Hochst. ex Endl. trees were developed, using a nonlinear mixed-ef... ... Repository: BDPA Publication year: 2024
To improve estimates of neotropical forest carbon stocks more direct measurements are needed: An example from the Southwestern Amazon. Author(s): MELO, A. W. F. de; LIMA, A. J. N.; OLIVEIRA, M. V. N. d'; SANTOS, J. dos; BRONW, I. F.; AMARAL, E. F. do; SILVA, S. S. da; OLIVEIRA, I.; CAMARGO, P. B. de; HIGUCHI, N. In our study, we conducted direct forest inventories in the SWA to address the following question: Do the allometric patterns, biomass, and carbon stocks observed in the Southwestern Amazon differ fro... ...

Volume estimate for three timber species with commercial interest from the diameter of the stump. Author(s): LIMA, Q. S. de; CUNHA, T. A. da; AMARO, M. A.; FIGUEIREDO, E. O.; PARENTE, P. R. F. Estimativa do volume para três espécies de interesse comercial madeireiras a partir do diâmetro do toco. O volume comercial de árvores pode ser calculado de forma direta e indireta. Entretanto em área... ... Repository: BDPA Publication year: 2021
Tree height and tropical forest biomass estimation. Author(s): HUNTER, M. O.; KELLER, M.; VICTORIA, D. de C.; MORTON, D. C. Tropical forests account for approximately half of above-ground carbon stored in global vegetation. However, uncertainties in tropical forest carbon stocks remain high because it is costly and laborio... ... Repository: BDPA Publication year: 2013
Sexual dimorphism and allometric effects associated with the wing shape of seven moth species of Sphingidae (Lepidoptera: Bombycoidea). Author(s): CAMARGO, W. R. F. de; CAMARGO, N. F. de; CORRÊA, D. do C. V.; CAMARGO, A. J. A. de; DINIZ, I. R. Abstract - Sexual dimorphism is a pronounced pattern of intraspecific variation in Lepidoptera. However, moths of the family Sphingidae (Lepidoptera: Bombycoidea) are considered exceptions to this rul... ... Repository: BDPA Publication year: 2015
