Alfredo Castillo-Guerrero

I studied marine biology at the Universidad del Mar (México). At that time, I carried out research about pesticides levels (POCs) in the blood of two seabirds species (Laughing gull and Magnificent frigatebird) and their relationship with the health condition of birds. Then, I got a master's degree in Environmental Management, during that time I studied the population genetic structure in the Red-billed Tropicbird in the Mexican Pacific. Nowadays, I am a doctoral student at the Justus Liebig University Giessen (Germany) under the supervision of Prof. Dr Petra Quillfeldt. My doctoral research focuses on determining the foraging and trophic ecology in the Red-billed Tropicbird in the Mexican Pacific using direct methods (diet analyses, data logger technology) and non-invasive methods (i.e. stable isotope analysis).
