A Note on the Philippine Journal of Science
Articles in Biology
By Dolores A. Ramirez, PhD
The biological sciences are very well represented in the papers published in the Philippine
Journal of Science from its first publication in 1906 to its centennial year in 2006. The most
outstanding, however, are the papers on the surveys and systematics of the Philippine flora and
fauna. From 1906 to 2006, more the 1300 papers on the systematics of Philippine plants, animals
(especially insects, birds and fishes) and microorganisms were published. A large number of the
species described were newly identified, some of which were established to be indigenous to the
Philippines. These publications stand as one testimony to the wide diversity of the Philippine flora
and fauna.
Selected for reprinting in this special centennial issue of PJS are only a few examples of the
scope of biology that are undertaken in the Philippines ranging from physiology, morphology and
anatomy, and ecology.
MUSGRAVE WE. 1906. The influence of symbiosis upon the pathogenecity of microorganisms. PJS 3(2):77-88.
BROWN WH and HEISE GW. 1917. The relation between light intensity and carbon dioxide
assimilation. PJS 12(1): 85-97.
BROWN WH, MERRILL ED and YATES HS. 1917. The revegetation of Volcano Island, Luzon, Philippine Islands, since the eruption of Taal Volcano in 1911. PJS 12, C. Botany (4): 177-248.
TUPAS GL and SAJISE PE. 1978. The role of savanna trees in plant siccession.II. Response of
some reforestation species to ecological conditions in a savanna ecosystem. PJS 107(1-2): 61-70.
DIONISIO-SESE ML. 1996. Carbomic anhydrase: Its physiological and evolutionary significance in the marine symbiont Prochloron. PJS 125 (3): 241-258.
