The Regulations for Official Doctoral Studies at the University of La Laguna describe in Article 10, points 3 and 4, the activities planned to promote supervision or co-supervision, in those cases academically justified, for the development of the program. Thus, the thesis may have another supervisor, who must meet the same requirements established for a thesis supervisor in that doctoral program, when there are academic reasons, such as thematic interdisciplinarity or programs developed in national or international collaboration, with prior authorization from the Academic Committee. Likewise, a new researcher or a professor or researcher with a minimum of research experience who does not meet the requirements established for a thesis supervisor may assume the duties of co-supervisor. In all cases, they must have a civil service or contractual relationship with the university or organization collaborating in the development of the program.

In the areas where research topics related to Biodiversity and Conservation are being conducted at the University of La Laguna, the involvement of faculty and researchers in supervising doctoral theses has been high. A large majority of faculty in these areas have committed to the program and have shown interest in supervising doctoral theses. Supervisors are increasingly offering more candidates than they are demanding from potential doctoral students, despite the fact that the number of doctoral students has remained stable throughout the program's implementation.

In this doctorate, it is also worth mentioning the participation of international experts in monitoring committees, in the preparation of preliminary reports or in the doctoral thesis committees. For those doctoral students who choose to include the International Mention in their doctoral degree, international experts will be responsible for the stays that the doctoral student will have to carry out outside Spain under their supervision, in a prestigious higher education institution or research centre, where they will carry out additional training or research work. In addition, these doctoral theses will have to be reported on by a minimum of two doctoral experts belonging to a foreign higher education institution or research institute. Finally, at least one foreign expert, with a doctoral degree, and different from the person responsible for the stay will be part of the thesis evaluation committee.
