Assessment of the dendrochronological potential of Licaria bahiana Kurz, an endemic laurel of lowland Atlantic forests in Brazil

Tree-ring distinctness, dating potential and climatic sensitivity of laurel forest tree species in Tenerife Island

“…Crossdating performed on tree-ring series of those species with clear ring boundary distinctness and adequate sample size demonstrated that datable ring width series and site chronologies of enough quality can be obtained from tree species of the Tenerife laurel forests. The statistics of the tree-ring chronologies for the four studied species were within the common range of variation of MS (0.25-0.74), and even surpassed the common variation range of r xy (0.15-0.60) and EPS (0.27-0.94) found in tropical and subtropical tree-ring chronologies (Locoselli et al, 2013;Mendivelso et al, 2014;López and Villalba, 2016;Pagotto et al, 2017;Islam et al, 2018;Blagitz et al, 2019;Fontana et al, 2019;Marcelo-Peña et al, 2019). Statistics of the studied tree-ring chronologies were also similar than those from the conifers Juniperus brevifolia and Pinus canariensis in Azores and the Canaries, respectively (Rozas et al, 2013;Weigel et al, 2018;Pavão et al, 2022).…”

“…These evidences indicate that ring width series from laurel forests tree species have analogous dendrochronological potential than Macaronesian conifers and tree species from tropical and subtropical forests worldwide. The high EPS values of L. novocanariensis and P. indica tree-ring chronologies supported that tree species of the Lauraceae family show a strong common signal and are appropriate for dendrochronological studies (Reis-Avila and Oliveira, 2017; Fontana et al, 2019). It is necessary to increase the sampling effort in other species of the Lauraceae family, such as Ocotea foetens, which had well-defined ring boundaries but robust dating could not be performed due to the low number of sampled individuals.…”

“…Changes in colors that allowed differentiating ring boundaries in the wood of Laurus novocanariensis, Ocotea foetens and Persea indica was due to the alternance of thin-walled fibres in the earlywood versus thickwalled and flattened fibres in the latewood, which is common in the Lauraceae family (Reis-Avila and Oliveira, 2017). Tree-ring boundary distinctness has been previously established for Mediterranean and Macaronesian Laurus species (Schweingruber, 1990;Morales et al, 2002;Pupo-Correia, 2016;Matos et al, 2019), and for diverse species of Lauraceae from tropical and subtropical areas as well (Reis-Avila and Oliveira, 2017; Fontana et al, 2019;Godoy-Veiga et al, 2019). The wood of Apollonias barbujana, the fourth species of the Lauraceae family, showed clearly distinct tree rings in Madeira Island (Pupo-Correia, 2016).…”

Evaluación de la densidad y manejo forestal del piptocoma discolor (Pigüe) y otras especies en la provincia de Pastaza – Ecuador

“…Las especies encontradas fueron 90 especies, de las cuales se eliminaron 81 especies, porque tienen un bajo % de representatividad, quedando solo con 9 especies forestales, por su potencial productivo como una ventaja para el manejo forestal de árboles o arbustos sostenible y sustentable (Natalini et al, 2016). Si bien es cierto que utilizan el conteo de anillos para algunos árboles, que representan las temporadas de crecimiento del árbol y permite desarrollar los planes de manejo forestal (Rojas-García et al, 2020), se observaron anillos de crecimiento distintos en algunos individuos (Fontana et al, 2019). En la figura 4 se presenta el número de individuos y su predominancia o abundancia.…”

Climate change in the southern Amazonian Tropical Forest assessed by dendrochronological multiproxy

“…showing better climatic signals than RW or RD . Further, several studies carried out in tropical forests outside the Amazon region have shown a strong direct influence of temperature on tree growth (Fontana et al, 2019;Sullivan et al, 2020), affecting physiological processes and consequently elemental distribution and concentration in xylem tissues .…”
