“…Harrison and colleagues (2013) suggested that species with isoprene synthase will preferentially emit isoprene, to the detriment of monoterpenes, and in those species that emit both compounds there is competition between precursors and reducing power. Although monoterpenes are prevalent in stem storage resins of tropical trees in the Amazon (Piva et al, 2019), recent studies using 13 CO 2 have demonstrated that leaf emissions in the tropics do not derive from storage resins. Instead, they derive from biosynthesis linked with photosynthesis as a carbon source like isoprene (Jardine et al, 2017).…”

Graphical illustration of the biochemical, ecological, and atmospheric roles of volatile isoprenoids (isoprene and monoterpenes) within plants, ecosystems, and the atmosphere. Volatile isoprenoids protect photosynthesis during abiotic stress, are involved in multi-trophic interactions within ecosystems, and following atmospheric oxidation, impact climate through influences over secondary organic aerosol (SOA) and cloud condensation nuclei (CCN) lifecycles in the troposphere.

“…The volume yield in the sawmill can be affected by compounds in the wood such as terpenoids, acidic resins, and phenolic substances, which are present in some species and can affect the operation of sawmill equipment [36,67,69] and cause variations in the ease with which logs can be cut, as well as in the yield of each processed log. The carbon yield coefficient (CYC) of the log, the VYC, and the basic wood density were key factors in determining the low carbon storage in the low wood-density species, as was also observed by Nogueira et al [62], Chave et al [61], and Goodman et al [57].…”

Amazon forest management plans have a variety of effects on carbon emissions, both positive and negative. All of these effects need to be quantified to assess the role of this land use in climate change. Here, we contribute to this effort by evaluating the carbon stocks in logs and timber products from an area under forest management in the southeastern portion of Acre State, Brazil. One hundred and thirty-six trees of 12 species had DBH ranging from 50.9 cm to 149.9 cm. Basic wood density ranged from 0.3 cm−3 to 0.8 g cm−3 with an average of 0.6 g cm−3. The logs had a total volume of 925.2 m3, biomass of 564 Mg, and carbon stock of 484.2 MgC. The average volumetric yield coefficient (VYC) was 52.3% and the carbon yield coefficient (CYC) was 53.2% for logs of the 12 species. The sawn-wood products had a total volume of 484.2 m3, biomass of 302.6 Mg, and carbon stock of 149.9 MgC. Contributions of the different species to the total carbon stored in sawn-wood products ranged from 2.2% to 21.0%. Means and standard deviations for carbon transferred to sawn-wood products per-species from the 1252.8-ha harvested area ranged from 0.4 ± 1.1 MgC to 2.9 ± 0.4 MgC, with the largest percentages of the total carbon stored in wood products being from Dipteryx odorata (21.0%), Apuleia leiocarpa (18.7%), and Eschweilera grandiflora (11.7%). A total of 44,783 pieces of sawn lumber (such as rafters, planks, boards, battens, beams, and small beams) was obtained from logs derived from these trees. Lumber production was highest for boards (54.6% of volume, 47.4% of carbon) and lowest for small beams (1.9% of volume, 2.3% of carbon). The conversion factor for transforming log volume into carbon stored in sawn-wood products was 16.2%. Our results also show that species that retain low amounts of carbon should be allowed to remain in the forest, thereby avoiding low sawmill yield (and consequent generation of waste) and allowing these trees to continue fulfilling environmental functions.

“…Isoprene is the most common de novo biosynthesized compound, with isoprene‐emitting plants found as a typical component in tropical forests (Harley et al., 2004; Šimpraga et al., 2019; Taylor et al., 2018). Further species, such as monoterpenes are also released de novo from the leaves, glands and resin ducts (Kesselmeier & Staudt, 1999) in Amazonia (Jardine, Jardine, et al, 2015; Kuhn, Rottenberger, Biesenthal, Wolf, et al, 2002; Piva et al., 2019; Yáñez‐Serrano, Nölscher, et al, 2018).…”

“…Within such large ecosystems, ecological interactions may have an important, but poorly explored, role in regulating the BVOC emissions of the Amazon rainforest.4 | ECOLOG I C AL INTER AC TI ON SBiogenic volatile organic compounds are assumed to play a strong role in ecological interactions in Amazonia (Figure 2). BVOC sources create volatile blends that can serve to identify the species of a recipient(Piva et al, 2019), allowing us to understand the nature of such communication (e.g. 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).…”

Biogenic volatile organic compounds (BVOCs) play important roles at cellular, foliar, ecosystem and atmospheric levels. The Amazonian rainforest represents one of the major global sources of BVOCs, so its study is essential for understanding BVOC dynamics. It also provides insights into the role of such large and biodiverse forest ecosystem in regional and global atmospheric chemistry and climate. We review the current information on Amazonian BVOCs and identify future research priorities exploring biogenic emissions and drivers, ecological interactions, atmospheric impacts, depositional processes and modifications to BVOC dynamics due to changes in climate and land cover. A feedback loop between Amazonian BVOCs and the trends of climate and land-use changes in Amazonia is then constructed. Satellite observations and model simulation time series demonstrate the validity of the proposed loop showing a combined effect of climate change and deforestation on BVOC emission in Amazonia. A decreasing trend of isoprene during the wet season, most likely due to forest biomass loss, and an increasing trend of the sesquiterpene to isoprene ratio during the dry season suggest increasing temperature stress-induced emissions due to climate change.
