The doctoral study program Ecology is organized and implemented by the Faculty of Biology, University of Belgrade, in cooperation with experts from other relevant institutions. The study program carries a total of 180 ECTS credits, lasts 3 years and includes four modules: Plant ecology and phytogeography, Animal ecology and biogeography, Conservation ecology and environmental protection и Hydroecology. Two compulsory courses are organized that are unique to the study program and related to the preparation of a doctoral dissertation, five compulsory seminars and work on the preparation of a doctoral dissertation. For all modules, classes are organized from a larger number of elective courses that are organized into a single elective block. For each module, one of the elective courses is defined as a compulsory elective for a given module. Each student acquires 45 ECTS credits from elective courses during the course of their studies. 

In agreement with the mentor, the student may choose elective courses from other study programs organized by the Faculty of Biology. The elective part of the program is planned according to the individual needs of the candidate, depending on previous education and experience.

The program is implemented through: (1) active teaching that includes lectures, other forms of interactive theoretical teaching and study research work and (2) individual work of students.

The lead teacher is responsible for organizing teaching within his/her subject. As a rule, the lead teacher hires several lecturers, each of whom implements that part of the program of a given subject for which he/she is scientifically competent. Depending on the circumstances, guest lecturers from the country and abroad are also hired.

The preparation of each student's doctoral dissertation is monitored by a three-member committee, which includes two other members in addition to the mentor. The role of these committees is to monitor the progress of students and assist in the implementation of their research programs.
