“…The high number of trees Campsiandra laurifolia and Mabea caudata in the lower M3 stratum also corroborates the efficiency of methods M 2 and M 3 , because they are medium-sized species that are between 7 and 12 m high (Silva et al 1988, Dezzeo et al 2003, Silva 2013) and rarely reach Ht higher than 15 m, thus being within the limits calculated for the lower M2 (4.0 -10.9 m) and mean M3 (4.0 -9.9 m) strata. In a contact area of the Jaci-Paraná and Madeira Rivers in the state of Rondônia, Reis (2010) observed that trees of Campsiandra laurifolia and Mabea caudata had, on average, 12.0 and 11.0 m, respectively.…”

“…The same species, considering the method M 1 , were characteristic of the mean M1 stratum; however, this behavior seems illogical, based on the results and observations mentioned above. Therefore, considering the boundaries of the lower M1 (4 -5.9 m) stratum, the mean Ht of the species Campsiandra laurifolia (8.0 ± 3.4 m) and Mabea caudata (7.0 ± 2.2 m) and the Ht obtained in other surveys (Dezzeo et al 2003, Reis 2010, Rodrigues et al 2012, one can deduce that the upper limit of the lower M1 stratum was not correctly estimated, as observed through the discriminant analysis, which revealed that one of the height classes was wrongly allocated in the mean M1 stratum, resulting in a hit rate of 88.9 %. The probable reason for this situation was the significant deviation of Ht from a standard normal distribution.…”

“…The external factor controlling the growth rhythm of trees in tropical climates is intra-annual variation of rainfall in non-flooded upland forests (Worbes et al 2003;Fichtler et al 2004). On the other hand, the annual occurrence of long-term inundations in floodplain forests results in annual ring formation during high water level due to anaerobic conditions for roots affecting internal water transport of trees leading to leaf shedding (Scho ¨ngart et al 2002;Dezzeo et al 2003).…”

Dendrochronological records of a pioneer tree species containing ENSO signal in the Pantanal, Brazil

The Pantanal is subjected to a monomodal and predictable flood pulse of low amplitude which is the main driver of ecological processes and patterns of biodiversity in one of the largest wetlands in the world. Nevertheless, little is known about how the plant communities of this wetland respond to predicted climate changes. In this paper, we used tree-ring analyses of Vochysia divergens Pohl (Vochysiaceae), a light-demanding pioneer species that occurs in periodically or short-term flooded areas in the Cerrado and Pantanal. We evaluated the influence of precipitation and water level on the growth rates of this species, where it occurs, to determine how local climatic variables (precipitation and water level) influence tree growth and how a large-scale climatic driver in the tropical eastern Pacific (El Nin ˜o events) could affect both tree growth and local climate in the northern region of the Pantanal. The indexed tree-ring chronology of eight individuals had a significant relationship with annual precipitation (r = 0.22). Interannual variations of the water level did not affect tree growth. Sea surface temperature anomalies of the El Nin ˜o 1 ? 2 region lead to decreased precipitation in the northern region of the Pantanal, resulting in decreased diameter increments of V. divergens. Our results demonstrated the dendrochronological potential of V. divergens for analyzing climate-growth relationships for developing climate-sensitive proxies for reconstructing past climatic conditions.

“…Seasonality of cambial activity in the tropics has been mostly reported in water-stressed environments (Boninsegna et al 1989;Devall et al 1995;Worbes 1999;Enquist and Leffler 2001;Worbes et al 2003;Lisi et al 2008) and flooded forests (Worbes 1988(Worbes , 1989Callado et al 2001;Schöngart et al 2002;Dezzeo et al 2003). However, cyclic production of wood may also occur on mesic and moderately warm environments, such as wet forests (Vetter and Botosso 1989;Fichtler et al 2003).…”

Information on the timing and dynamics of tree ring formation is essential to assess the seasonal behavior of secondary wood growth and its associated environmental influences. Araucaria angustifolia is a dominant species in highland pluvial ecosystems of southeastern South America. Previous investigations indicated that their growth rings are formed annually, but no information exists about the timing of growth ring formation and the environmental triggers influencing cambium activity. In this paper we examine inter-and intra-annual cambial activity in A. angustifolia, through anatomical and dendrochronological evidence at two study sites, and model the relationships between regional climate variation and intraannual tree ring formation. The results confirm the annual growth ring formation in A. angustifolia and indicate that its growth season extends from October to April. Day length and temperature were the main environmental factors influencing the seasonal cambium activity. Our results evidence the dendrochronological potential of A. angustifolia for ecological and climatological studies in southeastern South America.
