Effect of temperatures on the behavior of the raft Ochroma pyramidale (Cav. ex Lam. Urb.) Under the conditions of climate change in the Los Rios province, Ecuador

Abstract

The different forest species that grow and develop in Ecuadorian areas respond to specific climatic requirements of each species, so the ecological coincidence that they manage to achieve in the habitats where they settle will be a guarantee to achieve acceptable wood production, in addition to representing a sustainable action involving social satisfaction, good economic results and the protection and conservation of the environment. The studies carried out on the effect of temperatures on the Balsa (Ochroma pyramidale) in the Los Ríos province in the scenarios of the periods 2011 – 2040; 2041 – 2070; and 2071 – 2100 found that the increase in temperatures in the RCP 6.0 2011-40 scenario favored the pond habitat, determining that the regions to the North, with low temperatures, will move to the Favorable category. The greatest increases in temperatures in the 2041-70 and 2071-100 scenarios determined which regions to the South for the pond will move to the Moderate and Unfavorable category, respectively. On the other hand, the increase in temperatures in the RCP 8.5 2011-40 scenario determined that the regions towards the North for the pond will be favored, going from Moderate to Favorable, while some regions towards the South will go from Favorable to Moderate. In the 2041-70 scenario, more than 80% of the southern regions for the raft moved to Moderate with sections in Unfavorable, while in 2071-100 more than 80% of the southern regions moved to the Unfavorable category.
