by Luca Marazzi* Why
is it important to study algae?
To start with, algae produce ~ 50% of the oxygen on planet Earth, they are food
for small and large animals that in turn are eaten by people, but they also
recycle nutrients and absorb CO2 from the air; by existing and doing
their own thing, these microorganisms provide these so called ecosystem
services to human beings (Fig. 1). Moreover, as algae reproduce fast and are
often adapted to specific environmental conditions, understanding how many
species of algae, and which ones, live where and why give us cues as to the
health of aquatic ecosystems, such as rivers, lakes, and wetlands. Fig. 1. Simplified scheme

Ever wonder what an alligator's breath smells like? One of the perks of my research is I get to hang out within sneezing distance of the amazing reptiles and I can tell you from first hand experience that their breath smells like death. Two of the major questions I try to answer with my research is what do alligators eat in the coastal Everglades and where do they eat it? To get at these questions, I use two different techniques: stomach contents analysis (SCA) and stable isotope analysis (SIA).
