Abstract:
During the first 2 months of the rainy season, small terrestrial rodents
(Liomys salvini, Sigmodon hispidus, Oryzomys fulvescens) were lietrapped
in the 11 largest habitats in Santa Rosa National Park, Guanacaste
Province, Costa Rica (Abandoned Horse Pasture, Upland Mixed
Deciduous Forest, Unburned Grassland, Burned Grassland, Oak Forest
Edge, Bosque Humido, Xeric Ridge, Lowland Mixed Deciduous Forest,
Lowland Evergreen Forest, Caesalpinia-Prosopis Swamp, Mangrove
Swamp). Small rodents occurred in all 11 habitats but at greatly differing
densities. L. salvin; was prominent in forest habitats and most
abundant in Upland Mixed Deciduous Forest, but also occurred in nonforested
habitats. S. hispidus was prominent in non-forested habitats,
was most common in Abandoned Horse Pasture, and occurred sparsely
in forested habitats. O. palustris occurred only in the habitats immediately
adjacent to the ocean and was most abundant in Mangrove Swamp.
