manages the UPLB Museum of Natural History, which was established in 1976 at the foothills of Mt. Makiling. It holds over 600,000 biological specimens, including half of the specimens from the Philippine Water Bug Inventory Project, and a third of the Dioscoro S. Rabor Wildlife Collection. More than half of the specimens belong to the entomological collection. While most of its collections are in its main building, some are housed in other UPLB units. Research Six research institutes were named Centers of Excellence in Research via Presidential decree: Institute of Plant Breeding, Institute of Food Science and Technology, Institute of Animal Science, National Crop Protection Center, Farming Systems and Soil Resources Institute, and National Institute of Molecular Biology and Biotechnology. UPLB hosts a number of international research institutes, including the Southeast Asian Regional Center for Graduate Study and Research in Agriculture, the ASEAN Center for Biodiversity, the International Rice Research Institute, the World Fish Center, the World Agroforestry Center, and the Asia Rice Foundation. The APEC Center for Technology Exchange and Training for Small and Medium Enterprises (ACTETSME), established in 1996 through the initiative of then President Fidel V. Ramos during the Asia-Pacific Economic Cooperation (APEC) Leaders' Meeting in Seattle, USA, is also located at the university's Science & Technology Park. Local research institutions such as the Department of Environment and Natural Resources' Ecosystems Research and Development Bureau, Department of Science and Technology's Forest Products Research and Development Institute, and Department of Agriculture's Philippine Carabao Center are headquartered or have offices at the university. The main office of IRRI's Philippine counterpart, the Philippine Rice Research Institute, used to be located at UPLB but was transferred to Muñoz, Nueva Ecija in 1990. It continues to maintain a research office at the university. Three UPLB-published journals, the Philippine Agricultural Scientist, the Philippine Journal of Veterinary Medicine, and the Journal of Environmental Sciences and Management are listed in the SCImago Journal Rankings. SCImago gave these an h-index (a measure of "actual scientific productivity" and "apparent scientific impact") of 13, 4 and 8, respectively. These journals are also listed in the ISI Web of Knowledge, along with two other UPLB-published journals: the Philippine Entomologist and the Philippine Journal of Crop Science. Biotechnology research One of the earliest innovations of UPLB was the production of CAC 87 sugar cane in 1919. This high-yielding variety is resistant to fiji and mosaic viruses, and produces more sucrose
