Extrinsic regime shifts drive abrupt changes in regeneration dynamics at upper treeline in the Rocky Mountains, USA

GP Elliott - Ecology, 2012 - Wiley Online Library
Given the widespread and often dramatic influence of climate change on terrestrial
ecosystems, it is increasingly common for abrupt threshold changes to occur, yet explicitly …

Canopy structure and below-canopy temperatures interact to shape seedling response to disturbance in a Rocky Mountain subalpine forest

AR Carlson, JS Sibold, JF Negrón - Forest ecology and management, 2020 - Elsevier
We examined the effects of two recent, high-severity disturbances on seed dispersal and

Fire catalyzed rapid ecological change in lowland coniferous forests of the Pacific Northwest over the past 14,000 years

SD Crausbay, PE Higuera, DG Sprugel, LB Brubaker - Ecology, 2017 - Wiley Online Library
Disturbance can catalyze rapid ecological change by causing widespread mortality and

Forest restoration limits megafires and supports species conservation under climate change

GM Jones, AR Keyser, AL Westerling… - Frontiers in Ecology …, 2022 - Wiley Online Library
Climate change and fire suppression have altered disturbance regimes in forest ecosystems

Tree species growth response to climate warming varies by forest canopy position in boreal and temperate forests

J Wang, L D'Orangeville, AR Taylor - Global Change Biology, 2023 - Wiley Online Library
Reports of forest sensitivity to climate change are based largely on the study of overstory
trees, which contribute significantly to forest growth and wood supply. However, juveniles in …

Fire interval effects on successional trajectory in boreal forests of northwest Canada

JF Johnstone, FS Chapin - Ecosystems, 2006 - Springer
Although succession may follow multiple pathways in a given environment, the causes of
