DENDROCHRONOLOGY AND RADIOCARBON DATING [PDF]

open access: yesRadiocarbon, 2021
ABSTRACTBoth dendrochronology and radiocarbon (14C) dating have their roots back in the early to mid-1900s. Although they were independently developed, they began to intertwine in the 1950s when the founder of dendrochronology, A. E. Douglass, provided dated wood samples for Willard Libby to test his emerging 14C methods.

Facilitative Effects of <i>Alnus viridis</i> ssp. <i>fruticosa</i> on <i>Betula nana</i> ssp. <i>exilis</i> Growth in Arctic Alaska. [PDF]

open access: yesEcol Evol
We investigated how Siberian alder influences the growth of dwarf birch in the low Alaskan Arctic. Using growth rings, we found that Siberian alder promotes dwarf birch growth overall despite delaying and shortening the growing season through enhancing snow depths.

Climate and Hydrology Shape the Growth and Water Use Efficiency in South Florida's (USA) Pine and Cypress Forests. [PDF]

open access: yesEcol Evol
In South Florida, tree growth and water‐use efficiency are significantly influenced by hydrological conditions, with water depth playing a more critical role than overall climate variables. Using dendrochronology and stable carbon isotopes, the study found that Taxodium species grow best during wetter summers, while Pinus elliottii grows most in wetter

Satellite Remote Sensing of Alpine Vegetation Dynamics: Challenges and Perspectives. [PDF]

open access: yesGlob Chang Biol
Satellite greening has become a key tool for monitoring alpine vegetation change, but a positive vegetation‐index trend is not an ecological observation in itself. This perspective shows that interpreting alpine greening requires addressing two sequential challenges: methodological complexity, which can bias trends during image processing, and ...
