Wildfire is an important natural disturbance agent, shaping mixed conifer forest structure throughout the Southwestern United States. Yet, fire exclusion caused by late 19th century livestock grazing followed by human fire suppression has altered for

The alpine treeline is a biogeographic transition zone that is an important indicator of environmental change. Here, I analyze spatial and temporal dynamics of vegetation in the alpine treeline ecotone in the Elk Mountains of western Colorado. I used

Investigating the composition and structure of old-growth forests provides information about the spatial and temporal variability of processes responsible for stand development, succession, and biogeographic patterns of forests. This study quantifies

It has long been hypothesized that trees growing at range limits likely also occur near the limit of their ecological amplitude and thus, should be more sensitive to climate variability than individuals growing nearer the range core. We developed a t

We present white spruce ( Picea glauca ) tree-ring width and maximum latewood density chronologies for two latitudinal treeline sites in northern interior Canada: along the Coppermine River in the Northwest Territories (NWT); and in the Thelon River

Fire is a key disturbance agent in the fire-prone mixed conifer and ponderosa pine forests of the southwestern United States. Human activities (i.e., livestock grazing, logging, and fire suppression) have resulted in the exclusion of fire from these

Extreme climate conditions have dramatic socio-economic impacts on human populations across the tropics. In Indonesia, severe drought and floods have been associated with El Ni˜ no-Southern Oscillation (ENSO) events that originate in the tropical In

[ 1] The west Pacific warm pool is the heat engine for the globe's climate system. Its vast moisture and heat exchange profoundly impact conditions in the tropics and higher latitudes. Here, September - November sea surface temperature (SST) variabil

[1] Monsoon droughts, which often coincide with El Nino warm events, can have profound impacts on the populations of Southeast Asia. Improved understanding and prediction of such events can be aided by high-resolution proxy climate records, but these
