Earlywood and latewood: new insight on the tree growth-climate response in the U.S. Southwest with emphasis on the summer monsoon.

Earlywood and latewood tree-ring chronologies offer promise for reconstructing season- specific, and in some cases, dual-season climate variability. This was our motivation for developing a new network of 50 intra-annual chronologies for the southwestern U.S., where annual precipitation is split between the westerly influenced winter and summer monsoon climate regimes.

Investigates native inhabitants of the US Southwest from its initial colonization over 11,000 years ago to the arrival of Europeans in AD 1540. Surveys past societies of the Southwest, including where they lived, their lifeways, and their material culture.

Fire History of Montane Grasslands and Ecotones of the Valles Caldera, New Mexico, USA

Montane grasslands are distributed across the Southwest, but there has been little quantitative study despite their biological and economic value. The study area is the montane forest-grassland ecotone within the Valles Caldera National Preserve (VCNP) northwest of Albuquerque, New Mexico, situated in the heart of the Jemez Mountains. We hypothesize that the fire history record of the ecotone should closely reflect the fire regimes in the montane grasslands throughout the study area and that this zone served as a pathway to encourage the spread of fire to other valles.
