LTER Network Planning Grant:Status and Activities
Mary L. Cadenasso
University of California, Davis
Goals and Objectives
• Network level
• Emphasize collaboration, synthesis, integration
• Objectives– Cross site collaboration and interdisciplinary
training– LTER network governance structure– LTER science into K-12 curriculum
Q1: How do long-term press disturbances and short-term pulse disturbances interact to alter ecosystem structure and function?
ECOSYSTEM FUNCTIONFlux, transport, storage,
transformation, stoichiometry,
productivity
COMMUNITY STRUCTUREVegetation turnover time
Trophic structureMicrobial communities
PULSES: Fire, drought, storms; dust events, pulse nutrient inputs; fertilization
PRESSES: Climate change; nutrient loading; sea-level rise; increased human resource use
