21st Century Warming, Site Aspect, and Reversal of Age-Related Growth Decline in Shortleaf Pine (Pinus echinata) in North Carolina, USA

open access: yesAtmosphere, 2023
We examined the influence of significant 21st century warming on the radial growth patterns of shortleaf pine growing on adjacent north/northeast- and south/southwest-facing slopes (hereafter NS and SS), in the Uwharrie Mountains of North Carolina, USA ...

Robust Tree-Ring Detection [PDF]

open access: yes, 2007
The study of tree-rings is a common task in dendrology. Usually the rings deliver information about the age of the tree, historic climate conditions and forest densities. Many different techniques exist to perform the tree-ring detection, but they commonly are semi-automatic.

Dendrochronology and Isotope Chronology of Juglans neotropica and Its Response to El Niño-Related Rainfall Events in Tropical Highlands of Piura, Northern Peru

open access: yesPlants
Tropical trees represent an important potential archive of climate and ecological information, but their dendrochronology based on conventional techniques has been challenging.

A narrow window of summer temperatures associated with shrub growth in Arctic Alaska

open access: yesEnvironmental Research Letters, 2020
Warming in recent decades has triggered shrub expansion in Arctic and alpine tundra, which is transforming these temperature-limited ecosystems and altering carbon and nutrient cycles, fire regimes, permafrost stability, land-surface climate-feedbacks ...

Comparing tree-ring based reconstructions of snowpack variability at different scales for the Navajo Nation

open access: yesClimate Services, 2021
Snowpack in the western U.S. is on the decline, largely attributed to increasing temperatures in the region. This is a critical issue for many Native American communities who disproportionately rely on local snow-fed water supplies.

Experimental reconstruction of monsoon drought variability for Australasia using tree rings and corals

open access: yesGeophysical Research Letters, 2008
An experimental reconstruction uses three well‐dated, annually‐resolved proxies from Australasia (0–40°S, 95–155°E) to provide large‐scale information on Sep–Jan Australasian monsoon variability based on the Palmer Drought Severity Index (PDSI) for 1787 ...
