“…ANNUAL DIAMETER GROWTH PATTERNS.-Mean annual Swietenia diameter growth increment increased predictably with total annual (July-June) rainfall and with rainfall totals during the first half of the growing season at Marajoara. This finding corroborates results from field studies in Mexico, Belize, and southwestern Amazonia showing that diameter growth rates by Swietenia increase with annual precipitation totals (Whigham et al 1998, Dünisch et al 2003, Shono & Snook 2006. Our data suggest that rainy season duration influences annual growth patterns more than total precipitation, that is, whether wet season onset occurs in September vs. October or even late November.…”

“…Successive drought years lowering phreatic water below average dry season levels can retard wet season recharge and exacerbate mortality in low-ground areas at the study site (Grogan & Galvão 2006). Studies demonstrating that shallow-rooting species are more sensitive to rainfall patterns (Noldt et al 2001, Dünisch et al 2003) support results reported here for Swietenia. This study's second deciduous species, Parkia, demonstrated quite different stem behavior with respect to annual rainfall totals, tending to grow more robustly during years with lower rainfall.…”

“…Dividing annual precipitation totals into 3-and 6-mo sub-totals (Dünisch et al 2003, Brienen & Zuidema 2005, both July-September (first 3 mo of the growing year) and October-December (second 3 mo) correlated strongly with mean annual diameter growth rates by Swietenia, and July-December (first 6 mo of the growing year) sub-totals yielded significant positive correlation (Table 2). Sub-totals for the second half of the growing year correlated weakly with annual growth rates.…”

Understanding tree growth in response to rainfall distribution is critical to predicting forest and species population responses to climate change. We investigated inter‐annual and seasonal variation in stem diameter by three emergent tree species in a seasonally dry tropical forest in southeast Pará, Brazil. Annual diameter growth rates by Swietenia macrophylla demonstrated strong positive correlation with annual rainfall totals during 1997–2009; Hymenaea courbaril growth rates demonstrated weak positive correlation, whereas Parkia pendula exhibited weak negative correlation. For both Swietenia and Hymenaea, annual diameter growth rates correlated positively and significantly with rainfall totals during the first 6 mo of the growing year (July to December). Vernier dendrometer bands monitored at 4‐wk intervals during 3–5 yr confirmed strong seasonal effects on stem diameter expansion. Individuals of all three species expanded in unison during wet season months and were static or even contracted during dry season months. Stems of the deciduous Swietenia contracted as crowns were shed during the early dry season, expanded slightly as new crowns were flushed, and then contracted further during 3–5 wk flowering periods in the late dry season by newly mature crowns. The three species’ physiographic distribution patterns at the study site may partially underlie observed differences in annual and seasonal growth. With most global circulation models predicting conditions becoming gradually drier in southeast Amazonia over the coming decades, species such as Swietenia that perform best on the ‘wet end’ of current conditions may experience reduced growth rates. However, population viability will not necessarily be threatened if life history and ecophysiological responses to changing conditions are compensatory.

In this study, we use tree-ring records to determine the climate factors controlling the growth of Centrolobium microchaete, a high-value timber species from the tropical dry Chiquitano forest in Bolivia. We present the first tree-ring chronologies from C. microchaete for Concepción and Santa Mónica, Bolivia. Statistical analyses show that the chronologies are of good quality and have a significant common signal between trees. The growth of C. microchaete is strongly influenced by climatic conditions during late spring-early summer. Abundant precipitations concurrent with below-average temperatures during this period of the year favor tree growth. Climate variations in late spring-early summer explain 4 40 percent of the total variance in C. microchaete tree growth during the interval 1943-2005. Minor differences in tree responses to climate recorded between the two stands may reflect differences in the extent of the dry season and in soil water capacity between sites. Although the chronologies cover the past 180 yr, adding samples from older individuals would permit the extension of these records further back in time. The strong climate dependency of tree growth suggests that predicted future climate changes in the region could have a significant influence on C. microchaete tree growth during the 21st century.Abstract in Spanish is available at http://www.blackwell-synergy.com/loi/btp.

“…The formation of fewer subannual rings, specially over the recent period, could be due to the age of the trees: older trees have lower rates of intra-annual structure formation (Dünisch, Ribeiro Montóia, & Bauch, 2003); stand/crown position: trees under suppressed growth conditions tend to form more intra-annual structures (Groenendijk et al, 2014); and/or physiological factors as root depth or less susceptibility to insect attacks (Copenheaver, Pokorski, Currie, & Abrams, 2006). Our results imply some important limitation to use the P. copaifera ring-width chronology for reconstructing the climate along the low Atrato River.…”

In temperate climates, tree growth dormancy usually ensures the annual nature of tree rings, but in tropical environments, determination of annual periodicity can be more complex. The purposes of the work are as follows: (1) to generate a reliable tree‐ring width chronology for Prioria copaifera Griseb. (Leguminoceae), a tropical tree species dwelling in the Atrato River floodplains, Colombia; (2) to assess the climate signal recorded by the tree‐ring records; and (3) to validate the annual periodicity of the tree rings using independent methods. We used standard dendrochronological procedures to generate the P. copaifera tree‐ring chronology. We used Pearson correlations to evaluate the relationship of the chronology with the meteorological records, climate regional indices, and gridded precipitation/sea surface temperature products. We also evaluated 24 high‐precision 14C measurements spread over a range of preselected tree rings, with assigned calendar years by dendrochronological techniques, before and after the bomb spike in order to validate the annual nature of the tree rings. The tree‐ring width chronology was statistically reliable, and it correlated significantly with local records of annual and October–December (OND) streamflow and precipitation across the upper river watershed (positive), and OND temperature (negative). It was also significantly related to the Oceanic Niño Index, Pacific Decadal Oscillation, and the Southern Oscillation Index, as well as sea surface temperatures over the Caribbean and the Pacific region. However, 14C high‐precision measurements over the tree rings demonstrated offsets of up to 40 years that indicate that P. copaifera can produce more than one ring in certain years. Results derived from the strongest climate–growth relationship during the most recent years of the record suggest that the climatic signal reported may be due to the presence of annual rings in some of those trees in recent years. Our study alerts about the risk of applying dendrochronology in species with challenging anatomical features defining tree rings, commonly found in the tropics, without an independent validation of annual periodicity of tree rings. High‐precision 14C measurements in multiple trees are a useful method to validate the identification of annual tree rings.
