Tropical tree growth driven by dry-season climate variability
Zuidema, Pieter A.; Babst, Flurin; Groenendijk, Peter; Trouet, Valerie; Abiyu, Abrham; Acuña-Soto, Rodolfo; Adenesky-Filho, EduardoInterannual variability in the global land carbon sink is strongly related to variations in tropical temperature and rainfall. This association suggests an important role for moisture-driven fluctuations in tropical vegetation productivity, but empirical evidence to quantify the responsible ecological processes is missing. Such evidence can be obtained from tree-ring data that quantify variability in a major ve...
Effects of morphological and environmental variation on the probability of Copa...
Guarino, Ernestino de Souza Gomes; Uller, Heitor Felippe; Esemann-Quadros, Karin; Gessner, Camila Mayara; da Silva, Ana Cláudia LopesThis study evaluated the morphological variation (total and commercial height, and diameter at 1.3 m above ground level - DBH) and environmental variables (slope, distance to water bodies, solar orientation, termites, tree damage and elevation) which influence production of oleoresin by Copaifera paupera (Herzog) Dwyer in southwestern Amazon. The present study was conducted at the experimental forest of Embrapa...
