“…If a bat was flying or at a roost only briefly, position sighted along a single bearing and distance was estimated from signal strength and gain (Law & Lean 1999, Winkelmann et al 2000, Bernard & Fenton 2003. Tracking stations were established at mapped reference locations usually within 20-100 m of activity centers for each bat.…”

Chestnut short-tailed bats, Carollia castanea, and Seba's short-tailed bats, C. perspicillata (Phyllostomidae), were radio-tracked (N = 1593 positions) in lowland rain forest at Tiputini Biodiversity Station, Orellana Province, Ecuador. For 11 C. castanea, mean home range was 6.8 ± 2.2 ha, mean core-use area was 1.7 ± 0.8 ha, and mean long axis across home range was 438 ± 106 m. For three C. perspicillata, mean home range was 5.5 ± 1.7 ha, mean core-use area was 1.3 ± 0.6 ha, and mean long axis was 493 ± 172 m. Groups of less than five C. castanea occupied day-roosts in earthen cavities that undercut banks the Tiputini River. Carollia perspicillata used tree hollows and buildings as day-roosts. Interspecific and intraspecific overlap among short-tailed bats occurred in core-use areas associated with clumps of fruiting Piper hispidum (peppers) and Cecropia sciadophylla. Piper hispidum seeds were present in 80 percent of the fecal samples from C. castanea and 56 percent of samples from C. perspicillata. Carollia perspicillata handled pepper fruits significantly faster than C. castanea; however, C. castanea commenced foraging before C. perspicillata emerged from day-roosts. Evidence for exploitative competition between C. castanea and C. perspicillata is suggested by our observations that 95 percent of ripe P. hispidum fruits available at sunset disappear before sunrise (N = 74 marked fruits). Piper hispidum plants produced zero to 12 ripe infructescences per plant each night during peak production. Few ripe infructescences of P. hispidum were available during the dry season; however, ripe infructescences of C. sciadophylla, remained abundant.Abstract in Spanish is available at http://www.blackwell-synergy.com/loi/btp.

“…Roost switching, however, may help reduce parasite loads (Lewis 1995; Reckardt & Kerth 2005) or prevent detection of roost sites as reliable prey sources by predators (Fenton et al. 1994; Winkelmann et al. 2000).…”

“…2004), probably because of the high availability of roosting resources. These abundant roosting resources, coupled with stable and abundant food resources, may further increase fidelity to particular roosting areas (Winkelmann et al. 2000; Chaverri et al.…”

Ecological Correlates of Roost Fidelity in the Tent‐Making Bat Artibeus watsoni

et al. 2007

Roost switching is a common occurrence in bats, yet the causes and consequences of such behavior are poorly understood. In this study we explore the ecological correlates of roost fidelity in the tent‐making bat Artibeus watsoni, particularly focusing on the effect of sex, reproductive status, and roost availability using a three‐factor general linear model (GLM). We estimated roost fidelity of radio‐tracked individuals and found that the GLM was significant (R2 = 0.72, F10,34 = 8.91, p < 0.001). Significant interaction terms were observed for relative roost availability and sex (F4,34 = 16.96, p < 0.001), and relative roost availability and reproductive status (F6,34 = 7.62, p < 0.001), indicating that variation in roost fidelity among males and females, and among individuals under different breeding conditions, depended on relative roost availability at the site where they were radio‐tracked. Individuals in areas of high roost availability exhibited lower roost fidelity than those sampled in areas of lower roost availability. Females exhibited less roost fidelity than males for all roost availability categories, but the difference between males and females was only significant at high roost availability. The general pattern of decreased roost fidelity as roost availability increased was also prevalent among individuals in different breeding conditions. Additionally, satellite males exhibited higher roost fidelity than resident males in areas of low roost availability, and lactating females had higher roost fidelity than non‐breeding females in areas of medium roost availability. Our study thus demonstrates that sex, reproductive status, and roost availability all affect roost fidelity in the tent‐making bat A. watsoni, and also suggests that roost availability is the most important factor influencing roost fidelity in this bat, providing the first quantitative evidence that roost fidelity is correlated with roost abundance in a single species.

“…Similarly, based on the recapture data, the average nightly foraging movement of the subcanopy frugivorous bats in peninsular Malaysia increases in relation to body mass (Hodgkison 2001). Previous studies showed that in several fruit bat species, males travel shorter distance than females to forage , Nair et al 1999, Winkelman 2000. Using radio tracking techniques, Funakoshi & Zubaid (1997) also showed that the larger C. horsfieldi had about double the home range size of the smaller C. brachyotis.…”

Resource Partitioning in Sympatric Cynopterus bats in Lowland Tropical Rain Forest, Thailand

2006

View full text Add to dashboard Cite

Diet and habitat use of the closely related and size-overlapping sympatric Cynopterus brachyotis and C. sphinx were established in lowland dry evergreen forest, Thailand, between March 1998 and March 2000. Feces from netted bats were analyzed, and the recapture rate determined. Although both species share a set of food plants, and fruits from early successional forest contribute about half of their diet, C. brachyotis, the smaller of the two species, ate a significantly greater proportion of fruits from early successional forest than C. sphinx. The latter ate a significantly greater proportion of fruit species in larger size classes. More C. brachyotis were captured in early successional forest in almost every month, while C. sphinx is more common in old-growth forest. However, the capture rate of C. sphinx increased in early successional forest in the mid-dry season when its preferred fruits become available. The recapture rate of C. brachyotis in early successional forest was significantly higher than that of C. sphinx, and the reverse situation was observed in old-growth forest. Male C. sphinx had a significantly higher recapture rate in early successional forest than females. Fruit size and habitat use are the major determinants of resource partitioning between these size-overlapping congeners.
