“…The IAWA classification and all others on distinction are arbitrary and subjective, based on the mental comparison of a researcher among a particular sample containing types of growth ring which he/she is accustomed to recognize. This approach generates different opinions on the degree of distinction of the growth rings and even on their recognition (Cherubini et al ., ). For example, many growth rings occurring in tropical species classified as distinct by anatomists of these regions (e.g.…”

“…The theme of annual rings still prevails in current literature, marginalizing those rings which do not show such periodicity and impeding discussion of the variation which occurs in the periodicity of this structure (De Micco et al ., ). Multiple rings are treated widely as ‘false rings’ (Pagotto et al ., , ; Schöngart et al ., ), intra‐annual density fluctuations (De Micco et al ., ) or even as anomalies, even though they are regularly formed (Cherubini et al ., , ; De Micco et al ., ). On the other hand, it is often assumed that rings formed in temperate regions are always annual without proper investigation of their seasonal pattern (e.g.…”

The growth ring concept: seeking a broader and unambiguous approach covering tropical species

The concept of growth rings is little discussed in the literature and their treatment remains somewhat confusing in terms of the diversity of structures described. This situation has a major impact on the study of growth rings in tropical species, in which variations and complexity are greater and accuracy of identification less good. The rigid conceptual delimitations used by dendrochronologists and wood anatomists of temperate regions cannot be applied to the study of growth rings in most tropical species, which has led to neglect of this subject. With the objective of discussing the concept of growth rings, the present study consists of a survey of anatomical, periodicity, causal and evolutionary aspects of the treatment of these structures as evidenced in previous studies, and the evaluation of their application and limitations to the development of this concept. Anatomical aspects arise through radial integrity, or the presence of early and late wood; the degree of distinction of the rings, which may vary from well to poorly defined; and tangential continuity, meaning that rings may form a complete circle in the transverse section of the trunk, or instead be tangentially discontinuous, lens-shaped or in wedges. In addition there are a diversity of anatomical markers which enable us to recognize growth rings. Regarding periodicity, the rings may be annual, infra-annual or supra-annual. Causal aspects include genetic, endogenous and environmental components. Evolutionary aspects continue to be insufficiently investigated, and although most comparative studies treat growth rings recognized by different markers as though they were a single character, it remains questionable whether they can be regarded as homologous or the result of homoplasy. We conclude that the elaboration of a robust but broad definition which can include all the variation observed in growth rings of tropical species is a complex task, which is only possible by overcoming the restrictions adopted by dendrochronologists and wood anatomists of temperate regions for whom growth rings are essentially annual, strongly demarcated, tangentially continuous and restricted to the most pronounced markers.

“…The cells are tiny and, owing to the contorted shape of the tree trunk, the fibre is very often twisted and irregular. With almost unidentifiable and often very irregular growth rings (Cherubini et al, 2014), the species is not really suitable for dendrochronological dating (Friedrich et al, 2006;Cherubini et al, 2013) (Fig. 4).…”

“…6). Olive trees do not make annual rings as claimed by Friedrich et al (Cherubini et al 2013); absent that claim, there is no valid basis for asserting a radiocarbon wiggle-match to the calibration curve. There is no way of determining where the tree grew in relation to pre-eruption gas emission sources on Thera.…”

Quantitative Methods in the Humanities and Social Sciences

View full text Add to dashboard Cite

Quantitative Methods in the Humanities and Social Sciences is a book series designed to foster research-based conversation with all parts of the university campus from buildings of ivy-covered stone to technologically savvy walls of glass. Scholarship from international researchers and the esteemed editorial board represents the farreaching applications of computational analysis, statistical models, computer-based programs, and other quantitative methods. Methods are integrated in a dialogue that is sensitive to the broader context of humanistic study and social science research. Scholars, including among others historians, archaeologists, classicists and linguists, promote this interdisciplinary approach. These texts teach new methodological approaches for contemporary research. Each volume exposes readers to a particular research method. Researchers and students then benefit from exposure to subtleties of the larger project or corpus of work in which the quantitative methods come to fruition.
