Marcos Fernandez Martinez, visiting scientist from the Center for Ecological Research and Forestry Applications with the University of Barcelona, Spain, will present the first CALMIT Seminar at 3 p.m. April 27 in Hardin Hall 901, 33rd and Holdrege streets.
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 this fact: Worldwide temperatures are increasing and precipitation regimes are changing, and while ecosystems are experiencing a continuous increase in CO2 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 writes. This seminar will present the main results of this research.
The research is broad and 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.
