“…The article of PitSch et al (2017) addresses the suitability of Cariniana estrellensis for dendrochronological and dendroecological investigations. The last paper (Ben et al 2017) presents for the first time a study on growth periodicity and stable carbon isotope ratios based on tree ring cellulose of a tree species with C 4 photosynthesis. These results are compared with the corresponding data of a C 3 tree species from the same habitat in Hawaii.…”

We are editing a new book in the Springer Tree Physiology Series entitled &#8220;Stable Isotopes in Tree Rings: Inferring Physiological, Climatic and Environmental Responses&#8221; due out in 2020. Because trees produce annual growth increments that can be precisely dated, annual and interannual variations in tree ring width and stable carbon, oxygen and hydrogen isotopes provide detailed records of past physiological responses to biotic and abiotic impacts over many decades and centuries. In contrast to non-living chronologies (ice cores, stalagmites etc.), trees modify base physical inputs in response to local microclimates through their physiological response to light, temperature, humidity, water availability, CO2 and nutrients. Although this can make interpretation of isotopic variation in organic matter more complicated, it also means that these proxies can provide a wealth of additional information. Thus, an understanding of the combined physical and biological drivers of isotope fractionation in tree rings is crucial for paleoclimate interpretation. In addition, tree rings and stable isotopes contained therein integrate dynamic environmental, phenological and developmental variation that can be used to study present organism function and recent anthropogenic influences apart from their use as proxies for conditions in the distant past. The last few decades have seen tremendous progress in understanding the mechanisms by which tree physiology modifies stable isotope fractionation in organic matter.This book will be the first to comprehensively cover the field of tree ring stable isotopes. This volume highlights how tree ring stable isotopes have been used to address a range of environmental issues from paleoclimatology to forest management, and anthropogenic impacts on forest growth. It evaluates strengths and weaknesses of isotope applications in tree rings. This book focuses on physiological mechanisms that influence isotopic signals and reflect environmental impacts. Each of the 25 chapters has been authored by leading experts providing the most recent developments in the area.

Stable Isotopes in Tree Rings

The study of stable isotopes in tree rings is relatively new, but growing research field in tropical forests. In this chapter, we review 53 studies that measured stable isotopes of C, O and/or N in tree rings of a total of 83 tropical tree species. Tree growth in tropical forests is generally determined by seasonality of precipitation, and not temperature. Consequently, temporal variation in both δ13C and δ18O has often been correlated to precipitation and variability of the El Niño Southern Oscillation (ENSO), which can affect weather systems throughout the tropics and subtropics. Currently, stable isotopes research in the tropics has mainly focused on (i) quantifying the effects of rising atmospheric CO2 concentration and climate change on tree physiology, (ii) identifying the drivers of growth variability and reconstruction of past climate, and (iii) the identification of annual rings in wood lacking anatomically distinct growth boundaries. In addition, some initial studies used tree-ring δ15N as a tool to assess anthropogenic change of the nitrogen cycle in tropical forests. Although stable isotope analyses in the tropics still faces methodological and interpretation issues, it is becoming an important tool for understanding the functioning of tropical forests and their resilience to global change.
