DendroSync: An R package to unravel synchrony patterns in tree-ring networks [PDF]
, 2017 Spatial synchrony refers to the presence of a common signal for a time-varying characteristic that, in dendrosciences, is shared among tree-ring chronologies from a particular area.

Juniper from Ethiopia contains a large-scale precipitation signal [PDF]
, 2008 Most semiarid regions are facing an increasing scarcity of woody vegetation due mainly to anthropogenic deforestation aggravated by climate changes. However, there is insufficient information to reconstruct past changes in climate and to evaluate the ...

Approaching a thermal tipping point in the Eurasian boreal forest at its southern margin
Communications Earth & Environment, 2023 Climate change is increasing the intensity and frequency of extreme heat events. Ecological responses to extreme heat will depend on vegetation physiology and thermal tolerance.

IntCal20 Tree Rings: An Archaeological Swot Analysis [PDF]
Radiocarbon, 2020 ABSTRACTWe undertook a strengths, weaknesses, opportunities, and threats (SWOT) analysis of Northern Hemisphere tree-ring datasets included in IntCal20 in order to evaluate their strategic fit with the demands of archaeological users. Case studies on wiggle-matching single tree rings from timbers in historic buildings and Bayesian modeling of series of

Branch rings, thinned rings, tree enveloping rings [PDF]
Israel Journal of Mathematics, 2006 We develop the theory of ``branch algebras'', which are infinite-dimensional associative algebras that are isomorphic, up to taking subrings of finite codimension, to a matrix ring over themselves. The main examples come from groups acting on trees. In particular, for every field k we construct a k-algebra K which (1) is finitely generated and infinite-
