| Abstract | A tree is as a natural archive of valuable environmental information that allows going back in time if its growth rings are precisely dated, and the indirect indicators or proxies they contain are well
understood. Dendroisotopy, a clever combination of dendrochronology and isotope geochemistry, is part of this process because it can provide a very informative look at the biogeochemical conditions of the past, and eventually help reconstructing
climate. This possibility exists because the mechanisms that govern the distribution of isotopes in trees are increasingly better known. This section briefly summarizes how dendroisotopy of carbon and oxygen may reflect environmental changes such as
the impact of atmospheric pollution, ecological changes, and particularly climatic conditions. |
| Summary | (Plain Language Summary, not published)
Here we consider trees as a natural archives containing valuable environmental information, which somehow allow going back in time if the growth rings
are precisely dated and the indirect indicators or 'proxies' they contain are well understood. Dendroisotopy, the wise combination of dendrochronology and isotope geochemistry, is part of this approach because it allows for a very informative look at
the biogeochemical conditions of the past, and possibly, reconstructing the climate. This is because the mechanisms that govern the distribution of isotopes in trees are getting better known. This text briefly summarizes why dendroisotopes of carbon
and oxygen may reflect environmental changes including the impact of air pollution, environmental changes, including climate conditions. |
