Local variance of atmospheric 14C concentrations around Fukushima Dai-ichi Nuclear Power Plant from 2010 to 2012 [PDF]

, 2017
Radiocarbon (14C) has been measured in single tree ring samples collected from the southwest of the Fukushima Dai-ichi Nuclear Power Plant. Our data indicate south-westwards dispersion of radiocarbon and the highest 14C activity observed so far in the ...

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

Geophysical 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 ...

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.

Tropical volcanoes synchronize eastern Canada with Northern Hemisphere millennial temperature variability

Nature Communications, 2022
A maximum latewood density based summer temperature reconstruction from eastern Canada shows recent warming is unprecedented over 1246 years, and tropical volcanism synchronizes regional and hemispheric summer temperatures at the multidecadal time scale.

Tumor mutational burden as a determinant of metastatic dissemination patterns

Molecular Oncology, EarlyView.
This study performed a comprehensive analysis of genomic data to elucidate whether metastasis in certain organs share genetic characteristics regardless of cancer type. No robust mutational patterns were identified across different metastatic locations and cancer types.

Drought intensity affects radial growth and recovery of P. schrenkiana at varying elevations in the Western Tianshan Mountains, China

Forest Ecosystems
As climate change intensifies, forests increasingly face the challenges posed by more frequent and severe droughts. However, the impacts of drought intensity on post-drought growth recovery and compensatory growth in trees remain poorly understood ...
