“…Dendrochronology has been successfully applied to savanna trees (Daniellia olivieri) and forest trees (Anogeissus leiocarpus, Diospyros abyssinica) in Comoé National Park (Schongart et al 2006), but not to Ceiba pentandra. However, other authors have used growth rings in a very close Neotropical species, Ceiba speciosa, for dendrochronology and dendroclimatology (Vasconcellosa et al 2019) and Ceiba pentandra growth rings are prominent (Duvall 2011). Nevertheless, our method should be validated by further studies in Comoé.…”

Primates often consume either bark or cambium (inner bark) as a fallback food to complete their diet during periods of food scarcity. Wild chimpanzees exhibit great behavioral diversity across Africa, as studies of new populations frequently reveal. Since 2014, we have been using a combination of camera traps and indirect signs to study the ecology and behavior of wild chimpanzees (Pan troglodytes verus) in Comoé National Park, Ivory Coast, to document and understand the behavioral adaptations that help them to survive in a savanna-forest mosaic landscape. We found that Comoé chimpanzees peel the bark of the buttresses of kapok tree (Ceiba pentandra) trees to eat the cambium underneath. Individuals of all sex/age classes across at least six neighboring communities peeled the bark, but only during the late rainy season and beginning of the dry season, when cambium may represent an important fallback food. Baboons (Papio anubis) also target the same trees but mainly eat the bark itself. Most of the bark-peeling wounds on Ceiba trees healed completely within 2 years, seemingly without any permanent damage. We recorded chimpanzees visiting trees in early stages of wound recovery but leaving them unpeeled. Only 6% of peeled trees (N = 53) were reexploited after a year, suggesting that chimpanzees waited for the rest of the trees to regrow the bark fully before peeling them again, thus using them sustainably. Many human groups of hunter-gatherers and herders exploited cambium sustainably in the past. The observation that similar sustainable bark-peeling behavior evolved in both chimpanzees and humans suggests that it has an important adaptive value in harsh environments when other food sources become seasonally scarce, by avoiding the depletion of the resource and keeping it available for periods of scarcity.

“…Dendrochronological studies developed in the Amazonian floodplains also showed a negative correlation between ring width and the amount of precipitation and flood pulse during the vegetation period (Schongart et al 2004). In Brazil, with the exception of the ecosystems investigated by Schongart et al (2004), other studies in tropical climate showed strong influence of precipitation in the radial growth (Callado & Guimarães 2010;Brandes et al 2011;Latorraca et al 2015;Locosselli et al 2016b;Souza et al 2016;Granato-Souza et al 2019;Vasconcellos et al 2019), whereas negative correlations are more often in subtropical climate (Oliveira et al 2010;Andreacci & Botosso 2014;Perone et al 2016;Kanieski 2017;Granato-Souza et al 2018a;b). As in L. bahiana, a study carried out with Chukrasia tabularis A. Juss.…”

“…A recent study of dendrochronology and dendroclimatology of Ceiba speciosa carried out in a contaminated urban area and in the Tinguá Biological Reserve in the state of Rio de Janeiro in Brazil, showed that the intercorrelation of the series in the forest and the urban area, in the species C. speciosa, the urban area presented a greater intercorrelation. This result was explained because in a natural forest the distance between the trees is smaller and the competition is greater and the competition in general from neighboring trees has a greater influence on their growth than in the climate variations (VASCONCELLOS;CALLADO, 2019).…”

“…2) the validation of growth patterns throughout life, improving the information of the permanent sample plots, and 3) the growth models that help forest management (BRIENEN et al, 2012;ROZENDAAL;ZUIDEMA, 2011). However, in recent years dendrochronological techniques have been used to relate the growth of forest species in urban areas, how these are having an impact on the local climate and also, to see the levels of urban pollution (PRETZSCH et al, 2017;VASCONCELLOS;CALLADO, 2019) due to the concern of climate change worldwide. However, these studies are still scarce and for example in Peru not yet studied.…”

Utilizando métodos dendrocronológicos, avaliamos os anéis de crescimento dessas espécies e sua relação com o clima. As amostras de madeira foram coletadas com a sonda Pressler. As medições e análises dos anéis de crescimento das espécies foram realizadas usando técnicas padrão de dendrocronologia. A série mestre (cronologia), correlacionada com os índices climáticos (precipitação e temperatura), obtidos no banco de dados meteorológico NOAA. Os anéis de crescimento das espécies que crescem na área urbana são diferençados e anuais, delimitados pelo parênquima marginal e porosidade semicircular, além disso, C. alliodora apresenta áreas fibrosas. Ambas as espécies apresentaram uma correlação entre as árvores acima de 0.50. As idades máximas foram de 13 anos para C. allidora e 32 anos para C. fissilis. Da mesma forma, a baixa correlação entre o clima e as cronologias das espécies pode sugerir a influência de outros fatores ecológicos ou antropogênicos que interferem no crescimento dessas espécies. Finalmente, é demonstrado o potencial das espécies florestais para estudos dendrocronológicos na área urbana de Puerto Maldonado, Peru. Palavras-chave: anéis de crescimento, crescimento radial, Cordia alliodora, Cedrela fissilis, Madre de Dios.
