“…We state that wood morphological adaptability is crucial to identifying the plasticity of TMCF trees to climate and micro-environmental variation (e.g., pH, high moisture and closed canopy) 15 . Previous studies on other Cedrela species produced similar results on Cedrela growth 24 – 26 . In this study, Cedrela species RWIs were correlated to T max through current March to April and negatively influenced growth rates in December (− 1); moreover, T min was not statistically significant with annual growth.…”

Cedrela species occur within the Tropical montane cloud forest (TMCF) and rainforest in North America (Mexico), Central and South America. We assessed the hypothesis that functional xylem hydraulic architecture might be influenced by specific climatic variations. We investigated the effect of climate on tree-ring width and vessel traits (diameter, vessel density, vulnerability index and hydraulic diameter) of three relict-endemic and threatened Cedrela species (Cedrela fissilis, C. nebulosa and C. angustifolia) inhabiting Peruvian Tropical Andean cloud forests. All Cedrela species showed a significant reduction in radial growth and adjusted vessel trait linked with temperature, precipitation, and evapotranspiration. Ring-width and vessel traits showed adaptation within Cedrela species, crucial to understanding a rough indication of the plant’s ability to withstand drought-induced embolism or cavitation. Our results provide evidence for hydraulic mechanisms that determine specific wood anatomical functionality to climatic variation and drought responses. Therefore, changing the frequency or intensity of future drought events might exceed the adaptive limits of TMCF tree species, resulting in a substantial reduction of hydraulic functionality in Peruvian Cedrela species.

“…Where El Niño together with the Sea Surface Temperature (SST) of the Pacific and Atlantic oceans modify the path of the Intertropical Convergence Zone (ITCZ) in South America, being able to intensify the rains or interrupt them, for example, the displacement in the austral summer causes the ITCZ to be located further to the southeast of the continent where low pressure brings a rainy summer and the displacement of the ITCZ further north (Central America) results in a drier winter in South America due to high pressure (Jimenez et al, 2019;. In this sense, several studies have shown the influence of the El Niño-Southern Oscillation and the Sea Surface Temperature (SST) on the growth of tropical trees through the study of growth rings Felfili et al, 2018;Menezes et al, 2022) and in Peru this kind of studies have also been carried out but on the coast and highlands of the country Requena et al, 2020;Rodríguez et al, 2005), but in the Peruvian jungle there is no research on this subject, being this area of the country where the forestry is carried out, which is why it is necessary to investigate the influence of El Niño-Southern Oscillation and Sea Surface Temperature (SST) on the growth of commercial tropical species.…”

Título DEDICATIONThis thesis is dedicated to my mother, Emperatriz Cahuana Aguilar, for her love and for instilling in me since I was a child to pursue my goals. To my wife, María Esther Villavicencio Paucarpura, for her love and unconditional support throughout this process, and finally, to my two sons, Leif Leonardo and Kaiki Adriel, who were my motivation and strength to move forward in this challenge. Mention to all of them that it is also their achievement. ACKNOWLEDGMENTSDoctoral studies are complex, and difficult, with happy and sometimes frustrating moments, even more so in a global pandemic process, however, I was always surrounded by people who helped and motivated me throughout this process. First of all, I would like to thank my advisor Mario Tomazello Filho, who motivated me from the first day of this new challenge, being by his side was very important in my comprehensive training, from aspects of teaching, research, directing the laboratory, facilitating development and progress of their advisors, in addition to sharing their friendship, which is the most important thing, being next to the person you admire is fantastic, thank you, Mario.In Peru, I want to thank everyone involved in the planning and field collection, and thank the Native community of Belgium through its president Mr. Nazareno Aspajo López and Eng. Enrique Pacheco Villanueva for the support with the wood samples, would also like to thank the forestry concession Corporación Forestal Tres Fronteras SRL, through its legal representative, Eng. Federico Ríos Torres, and especially the engineers Erick Grandez Piña and German Payeza Tuesta for their support and availability in collecting the wood samples. , without the samples of more than 166 trees nothing would have been done, thanks to all of them.In Brazil, I want to thank Dr. Moisés Silveira Lobão for his support in transporting the wood samples from the Brazilian border (Assis Brasil) to the city of Piracicaba in São Paulo with a little more than 3,800 kilometers traveled by the samples from the city of Puerto Maldonado in Peru. I thank the technician of the Wood Anatomy and Identification Laboratory (LAIM) of the Luiz de Queiroz Higher School of Agriculture (ESALQ) Aparecido Candido Siqueira for his invaluable support in sanding the wood, it was several weeks of work where we left tired and with a lot of wood debris on his face and nose and also for his support in obtaining wood samples for X-ray densitometry analysis.
