We studied the altitudinal and temporal patterns of species abundance and reproductive status for 18 Neotropical bat species during 17 continuous months in four ranges (low 50, mid–low 500, mid–high 1000, and high 2000 m a.s.l.) in an altitudinal gradient in Costa Rica. We found an efect of elevation on the abundance on ten species. We also found a combined efect of altitude and precipitation in two species; for example, Carollia castanea was more abundant at the low altitudinal range and during the high precipitation period, while Sturnira hondurensis was more abundant at the high altitudinal range and during the low precipitation period. We also found an efect of altitude and precipitation on the reproductive status of fve bat species. Carollia sowellii and C. castanea showed higher number of reproductive males in the low range and reproduc tive females in the low altitudinal range during the high precipitation period. We also found a larger number of reproductive males of Sturnira mordax in the mid–high range, while pregnant females were more abundant during the low precipitation period. Our results show altitudinal and temporal patterns of abundance and reproductive phenology that highlight the need for long-term studies of species assemblages along altitudinal gradients. This information is crucial to implement conserva tion strategies that are species-orientated, promoting habitat protection for a large number of species in altitudinal ranges involved at the specifc periods when bat abundance or reproduction is higher.
