The geosciences contribution along the 50 years of the Revista de Biología Tropical had been scarcity and episodic. Until now there are 2374 papers but only 21 (0.88%) have some relation with geological sciencies. It`s posible to reconize two periods with geological contributions, one between 1963 and 1978.
