Marcos Fernández Martínez, visiting scientist from the Center for Ecological Research and Forestry Applications with the University of Barcelona, Spain, will present the first CALMIT Seminar, “Nutrients matter most for determining spatio-temporal variability of ecosystem productivity,” which 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.

The research is broad and will be of interest to ecologists, agronomists, statisticians and climate scientists.
