Abstract
Given the prevailing uncertainties surrounding regional climate variability in southeastern Brazil, it is necessary to explore proxy records. The present dendrochronological study investigates the climate variations in the Neotropical estuarine system of the Rio Doce basin based on tree-rings records of 40 trees of Terminalia catappa Linn. The study demonstrates that annual growth rings of the species record the variations in regional precipitation, streamflow of the Rio Doce basin and surface temperature of the south Atlantic ocean. The variation in the South Atlantic Ocean Dipole Index (SAODI) directly affects precipitation and indirectly influences growth ring increment. The strong synchrony among the trees highlights the marked effect of precipitation seasonality regulated by SAODI. The trees exhibit robust growth during the dry period when Rio Doce's rains and streamflow decrease, emphasizing the potential of this chronology for climate and hydrological monitoring. The chronology of T. catappa, despite being short, is the first to provide information on the climate variability of a South America estuary ecosystem. Future studies should verify the influences of precipitation and SAODI on the growth of long-lived species aiming climate reconstructions in the region.
期刊介绍:
Agricultural and Forest Meteorology is an international journal for the publication of original articles and reviews on the inter-relationship between meteorology, agriculture, forestry, and natural ecosystems. Emphasis is on basic and applied scientific research relevant to practical problems in the field of plant and soil sciences, ecology and biogeochemistry as affected by weather as well as climate variability and change. Theoretical models should be tested against experimental data. Articles must appeal to an international audience. Special issues devoted to single topics are also published.
Typical topics include canopy micrometeorology (e.g. canopy radiation transfer, turbulence near the ground, evapotranspiration, energy balance, fluxes of trace gases), micrometeorological instrumentation (e.g., sensors for trace gases, flux measurement instruments, radiation measurement techniques), aerobiology (e.g. the dispersion of pollen, spores, insects and pesticides), biometeorology (e.g. the effect of weather and climate on plant distribution, crop yield, water-use efficiency, and plant phenology), forest-fire/weather interactions, and feedbacks from vegetation to weather and the climate system.
