DIETARY HABITS OF TWO THREATENED CO- ROOSTING FLYING FOXES (MEGACHIROPTERA), SUBIC BAY, PHILIPPINES By Samuel Cord Stier B.A. Brown University, 1990 Presented in partial fnlfillment of the requirements for the degree of Master of Science The University of Montana 2003 Approved by: Dr. Stephen F. Siebert, Chairperson Dean, Graduate School Date Stier, Sam C., M.S., May 2003 Forestry Dietary Habits of Two Threatened Co Roosting- Flying Foxes (Megachiroptera), Subic Bay, Philippines Director: Dr. Stephen F. Siebert I studied the dietary habits of two threatened flying fox species, Acerodon juhatus and Pteropus vampyrus, at Subic Bay, Philippines, in an effort to provide managers with information useful for protected area zoning, compatible use planning, hunter education/regulation, and forest restoration design. The results also provide insight into the autecology and interspecific relationships of these co roosting- species. I used fecal analysis, interviews of bat hunters, and personal observations to describe the dietary habits of both bat species. Dietary items were deemed ‘important’ if used consistently on a seasonal basis or throughout the year, ubiquitously throughout the population, and if they were of known nutritional importance. Of the 771 droppings examined over a 2.5 year period, seeds from Ficus spp. were predominant in the droppings of both species and met these criteria, particularly hemi epiphytic- species (41% of A. jubatus droppings) and Ficus variegata (34% of P. vampyrus droppings, 22% of A. jubatus droppings). Information from bat hunter interviews expanded the knowledge of dietary composition of both bat species, and corroborated the fecal analyses and personal observations. Results from this study suggestXhdLt A.
