A global overview of drought and heat-induced tree mortality reveals emerging climate change risks for forests
Greenhouse gas emissions have significantly altered global climate, and will continue to do so in the future. Increases in the frequency, duration, and/or severity of drought and heat stressExpand

Climatic and human influences on fire regimes in ponderosa pine forests in the Colorado Front Range.
In the northern Colorado Front Range, fire suppression during the 20th cen- tury is believed to have created a high hazard of catastrophic fire in ponderosa.pine (Pinus ponderosa) forests. Since theExpand

Contingent Pacific–Atlantic Ocean influence on multicentury wildfire synchrony over western North America
Widespread synchronous wildfires driven by climatic variation, such as those that swept western North America during 1996, 2000, and 2002, can result in major environmental and societal impacts.Expand

Disturbance regime and disturbance interactions in a Rocky Mountain subalpine forest
The spatial and temporal patterns of fire, snow avalanches and spruce beetle outbreaks were investigated in Marvine Lakes Valley in the Colorado Rocky Mountains in forests of Picea engelmannii, AbiesExpand

Factors predisposing episodic drought‐induced tree mortality in Nothofagus– site, climatic sensitivity and growth trends
Summary 1 Although climatic variability is a strong driving force for forest dynamics, drought-induced mortality has generally received much less attention than other types of disturbance. 2 Expand

EFFECTS OF CLIMATIC VARIABILITY ON FACILITATION OF TREE ESTABLISHMENT IN NORTHERN PATAGONIA
Facilitation of tree establishment by nurse shrubs, which ameliorate otherwise unfavorable microenvironmental conditions, is a widely studied phenomenon. However, relatively little is known about howExpand

FIRE HISTORY IN NORTHERN PATAGONIA: THE ROLES OF HUMANS AND CLIMATIC VARIATION
The effects of humans and climatic variation on fire history in northern Patagonia, Argentina, were examined by dating fire scars on 458 trees at 21 sites in rain forests of Fitzroya cupressoides andExpand

Climatic influences on fire regimes along a rain forest‐to‐xeric woodland gradient in northern Patagonia, Argentina
Influences of annual climatic variation on fire occurrence were examined along a rainfall gradient from temperate rainforest to xeric woodlands in northern Patagonia, Argentina. Fire chronologiesExpand

LANDSCAPE INFLUENCES ON OCCURRENCE AND SPREAD OF WILDFIRES IN PATAGONIAN FORESTS AND SHRUBLANDS
Spatial heterogeneity of vegetation types and the abiotic environment can influence the occurrence and spread of wildfires, but in some landscapes the importance of these effects varies underExpand

Isozyme variation and recent biogeographical history of the long-lived conifer Fitzroya cupressoides
Aim Palaeoenvironmental records of Pleistocene glaciation and associated vegetation changes in Patagonia have led to the hypothesis that during the last glacial maximum (LGM) tree species survivedExpand
