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

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

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

Atmosphere, 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 ...

Tree-ring metabolism of Larix sibirica indicating plant responses to climate change

Current Plant Biology
In this study, 61 xylem tissue samples of Larix sibirica (Siberian larch) were collected from Hami, Xinjiang, and employed as experimental materials. An untargeted metabolomic approach based on ultra-performance liquid chromatography coupled with tandem ...

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

Climate 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.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.
