“…the identity and density of an attacking herbivore;Pinto-Zevallos, Bezerra, Souza, & Ambrogi, 2018), and can also direct the evolution of plant chemical diversity(Salazar et al, 2018).Signalling within plants can be based on cascading signals of jasmonates, salicylates and ethylene, but also other types of BVOCs such as GLV, methanol or isoprenoids(Filella, Peñuelas, & Llusià, 2006;Matsui, 2016;Matsui, Sugimoto, Mano, Ozawa, & Takabayashi, 2012;Seco, Filella, Llusià, & Peñuelas, 2011). The function of their emission can be involved in: inducing the production of BVOCs that can downregulate floral volatiles to produce BVOCs associated with fruit ripening, inducing BVOC production for defensive purposes, or for individual plant coexistence(Kigathi, Weisser, Reichelt, Gershenzon, & Unsicker, 2019;Ninkovic, Rensing, Dahlin, & Markovic, 2019). However, to our knowledge, these processes have not been investigated in Amazonia.…”
