Marcos Fernández Martínez will present the first Center for Advanced Land Management Information Technologies Seminar at 3 p.m. April 27 in Hardin Hall, Room 901, 33rd and Holdrege streets. Martínez is a visiting scientist from the Center for Ecological Research and Forestry Applications with the University of Barcelona, Spain.

The talk, "Nutrients Matter Most for Determining Spatio-Temporal Variability of Ecosystem Productivity," will cover how human activities are changing the global climate and how it is affecting the biogeochemical cycles of carbon, nitrogen and phosphorus.

Martinez's research examines how worldwide temperatures are increasing and precipitation regimes are changing. While ecosystems are experiencing a continuous increase in carbon dioxide and nitrogen because of fossil fuel burning, phosphorus is becoming more and more limiting for ecosystems.

"Our investigations have found that nutrient availability is far more important than climate for determining certain ecosystem processes such as carbon sequestration, fruit production and the emission of biogenic volatile organic compounds," Martinez wrote.

This seminar will present the main results of his research, which is broad. The research will be of interest to ecologists, agronomists, statisticians and climate scientists.

The seminar is sponsored by the Center for Advanced Land Management Information Systems and the School of Natural Resources.
