Widespread and prolonged defoliation by the European winter moth, Operophtera brumata L., has occurred in forests of eastern Massachusetts for more than a decade and populations of winter moth continue to invade new areas of New England. This study characterized the forests of eastern Massachusetts invaded by winter moth and related the duration of winter moth defoliation estimated using dendro...

Larix chinensis Beissn., as a native, dominant and climate-sensitive coniferous species at Mount Taibai timberline, Qinling mountains, is rarely disturbed by anthropogenic activities; thus, it an ideal proxy for the investigation of climate change or vegetation evolution. In this study, we applied dendrochronological methods to L. tree-ring series from Mt. investigated relationships between wid...

Abstract The physiological characteristics of trees change with age, suggesting that growth-related climate signals vary over time. This study aimed to clarify the impacts different diameter classes on chronological Pinus massoniana Lamb. and its response climatic factors. Chronologies were established in small (14.1 cm), middle (27.3 large (34.6 cm) according dendrochronology. results show tha...
