BIOL. MAR. PhD. TATIANA ACOSTA PACHÓN
Research in Marine Ecology.
Education
​Bachelor’s Degree
Marine Biology at Jorge Tadeo Lozano University (Colombia).
​Master’s Degree
Management of Marine Resources at CICIMAR-IPN (National Polytechnic Institute).
Thesis: "Growth and isotopic variation of carbon and nitrogen in vibrissae of northern elephant seal (Mirounga angustirostris)".
Ph.D.
Marine Sciences at CICIMAR-IPN.
Thesis: "Ontogenetic variation in feeding habits of striped marlin (Kajikia audax) and swordfish (Xiphias gladius) in the Eastern Pacific".
Key contributions
-
Pioneered stable isotope techniques to study trophic habits, migrations, and ontogenetic changes in top predators.
-
Bridging trophic levels: Expanded research from top predators (e.g., swordfish) to primary producers (macroalgae) to understand ecosystem dynamics.
-
Academic leadership: Advises undergraduate/graduate students and directs theses in marine ecology.​
