Litvak, Marcy
The varied topography and large elevation gradients that characterize the arid and semi-arid Southwest create a wide range of climatic conditions - and associated biomes - within relatively short distances. This creates an ideal experimental system in which to study the effects of climate on ecosystems. Such studies are critical givien that the Southwestern U.S. has already experienced changes in climate that have altered precipitation patterns (Mote et al. 2005), and stands to experience dramatic climate change in the coming decades (Seager et al. 2007; Ting et al. 2007).

Bosque Ecosystem Monitoring Program
Submitted by amswann on Thu, 07/07/2011 - 9:44am
The late Dr. Clifford S. Crawford established the Sevilleta’s Schoolyard LTER Program which funds an educational outreach program known locally as the Bosque Ecosystem Monitoring Program (BEMP). The major focus of the program is to monitor key indicators of structural and functional change in the Middle Rio Grande riparian cottonwood forest ('bosque') corridor through central New Mexico, including the Sevilleta National Wildlife Refuge.

Core Site Phenology Study

Wetherill, Karen
Plant phenology or life-history pattern changes seasonally as plants grow, mature, flower, and produce fruit and seeds. Plant phenology follows seasonal patterns, yet annual variation may occur due to annual differences in the timing of rainfall and ambient temperature shifts. Foliage growth and fruit and seed production are important aspects of plant population dynamics and food resource availability for animals. The purpose of this study is to assess plant phenology patterns across a series of biotic communities that represent an environmental moisture gradient.
Long-term Intersite Decomposition Team (LIDET) Plant Litter Data
Submitted by amswann on Fri, 12/09/2011 - 12:38pmThe primary objective of this study is to examine the control that substrate quality and climate have on patterns of long-term decomposition and nitrogen accumulation in above- and below-ground fine litter. Of particular interest will be to examine the degree these two factors control the formation of stable organic matter and nitrogen after extensive decay.
