“…), noting that exploitation was the most intense for trees in the 20, 40, and 60 cm DBH categories, alternating with less-used 10, 30, and 50 cm DBH trees [ 16 ]. DBH is related to the age of the tree [ 31 ], which led the authors to suggest that there is a cycle of use according to the maturity of A. peregrina trees, which can live for 30 years or more [ 32 ]. As wild marmosets live for around 5–7 years [ 33 ], the trees thus exploited remained available for use by several generations of marmosets [ 16 ].…”

Knowledge of the pattern of exploitation of trees can help us understand the relationship between marmosets and plants, especially in declining forests, such as those in the Brazilian Cerrado. Black-tufted marmosets (Callithrix penicillata) regularly exploit exudates by gouging the bark of trees with their specialized teeth. Determining preferred tree species to exploit exudates is important for forest management aimed at maintaining an essential food source for urban marmosets. We characterized the tree species, dendrometry, and the characteristics of the holes made by marmosets to obtain exudates. Based on these data, we proposed a gouging effort index (Chiseling Suitability Index for Marmosets, ChiSI). We identified 16 species belonging to 10 families of trees with gouging marks made by marmosets. Eleven new tree species used by black-tufted marmosets for exudates were identified in urban forests in the Cerrado. Exudate exploration was predominantly of medium intensity, with round holes concentrated in the canopy. The species Tapirira guianensis and Croton urucana were preferred. The ChiSI was characterized by a narrow range for both T. guianensis and C. urucana. Despite the flexibility of obtaining exudates, the black-tufted marmosets concentrate their exploitation to only a few tree species. The T. guianensis and C. urucana tree species should be considered the most important species for management plans and the preservation of black-tufted marmosets that live in urban forests in the Cerrado.

“…We know that radial growth, usually measured in DBH, depends on several conditions, such as spacing, climate and soil types. Mattos and Seitz (2008) studied the formation of annual growth rings in Anadenanthera colubrina in the Pantanal, Mato Grosso State and estimated that the species takes at least 55 years to reach 40 cm in diameter. Obviously, it would be difficult to estimate the age of trees in the present study, as such estimate would depend on many factors.…”

We investigated wood samples of five Anadenanthera colubrina trees, aiming to study radial variation of anatomy and basic density. The trees were cut from "lote 5 do Rodoanel trecho sul" in Embu municipality, State of São Paulo, where vegetation is classified as Montane Ombrophilous Dense Forest and climate is classified as Cwa. We cut discs from the diameter at breast height-DBH, and then cut samples from pith-to-bark to anatomical and basic density analysis. The results suggest that Anadenanthera colubrina has a very common anatomical and basic density radial variation pattern from pith-to-bark between hardwoods with an increase in vessel diameter favoring hydraulic conductivity, fiber wall thickness and length, ray height and width, and basic density. While the negative relationship between vessel diameter and frequency is well reported for many species, it has not been observed in A. colubrina because vessel frequency oscillates radially. This typical radial pattern also occurs in other native species in planting conditions, already demonstrated by our group in other studies, obviously with some changes depending on species.

“…De outra maneira, a cada 10 cm de classe de DAP, o número de orifícios ativos adota uma alternância entre um pico e um nadir. O DAP, normalmente, está relacionado à idade da árvore (WANG et al, 2016), portanto, possivelmente existe um ciclo de exploração conforme o DAP, assim como na condição de maturidade dos angicos que são espécies arbóreas longevas e podem viver por mais de 30 anos (MATTOS & SEITZ, 2008). Esse tempo excede muitas gerações de saguis.…”

RESUMO Saguis do gênero Callithrix (Hershkovitz, 1977) são caraterizados por apresentarem diversas características morfofisiológicas para obtenção de exsudatos vegetais. Que escarificam orifícios na casca das árvores com uma dentição especializada. Assim, o objetivo do presente estudo foi investigar se existe um padrão na obtenção de exsudatos relacionados aos dados dendométricos (altura total e DAP) de Anadenanthera peregrina var. peregrina por Callithrix spp. em cinco fragmentos urbanos de Floresta Atlântica no município de Viçosa, Minas Gerais. Foram amostrados 39 indivíduos de A. peregrina. Todos esses indivíduos tiveram seus dados dentrométricos mensurados e os orifícios contabilizados. O número de orifícios por indivíduo arbóreo variou de oito a 2.288. Não encontrou-se um padrão de exploração conforme as classes de DAP e/ou altura total em A. peregrina, embora, pareça existir um ciclo relacionado ao evento de exploração ativa com as diferentes classes de DAP. Sendo angicos e saguis espécies pioneiras na sucessão ecológica, a exploração desta única espécie vegetal pelos grupos de saguis pode indicar que esta relação é importante para a colonização destes primatas em ambientes degradados. Neste estudo, pode-se ressaltar que A. peregrina é uma importante espécie fornecedora de exsudato vegetal para saguis na Mata Atlântica.

The objective of this study was to investigate whether there is a pattern in the acquisition of exudates according to dendométricos data (total height and DBH) of Anadenanthera peregrina var. peregrina by marmosets hybrids
