“…Caves are considered favorable shelters for bats and their parasites, for they provide a favorable microclimate. In such habitats, bat colonies, although variable seasonally, may include several hundred individuals (Kunz 1982). This tends to favor the ectoparasites by providing an abundant source of food, high success in dispersal, as well as protection and the favorable conditions of humidity and temperature (Marshall 1981).…”

“…Roosts play important roles during the life of bats (Kunz & Lumsden, 2003;Kunz, 1982). Hence, to understand how bats use them and which are the factors that influence these patterns could contribute to the development of management plans to ensure their survival (Fenton 1997) specially during critical periods of their annual cycle as hibernating and maternity.…”

“…The development of pregnancy and the growth of juveniles are heavily influenced by the quality of maternity roosts. These kinds of roosts are important social units (Boye & Dietz 2005) and the availability of suitable roosts with proper microclimate can promote different degrees of fidelity to these sites (Kunz 1982). Indeed, in many species, nursery colonies are quite faithful to their location, returning every year to the same site (Lewis 1995), a tendency called natal philopatry.…”

Almost all bats are exclusively nocturnal. However, the activity patterns throughout the night can differ between species and also within the same species from place to place. Rhinolophus hipposideros (Bechstein, 1800) has suffered a severe decline in many countries along its distribution area, including Portugal. In this study we aimed to describe the roosting behaviour during spring, summer and autumn of one of the largest maternity colonies of R. hipposideros known in Portugal. We analysed roost occupancy, activity patterns inside the roost, birth periods, and post-natal behaviour. We also tested the influence of ambient factors on the patterns of roost use. All information was obtained through the analyses of video recorded using cameras placed inside the roost, while climatic data were gathered using a meteorological station. We found that this roost has higher occupation during August and that in October it is only occupied during the night. Females gave birth from late May to early June, and in August juveniles became independent and undistinguishable from the adults. This colony presented a bimodal pattern of activity throughout the months of the study, which seems to be related with sunset and sunrise. Our results indicate that individuals of this colony prefer higher temperatures, but low humidity and wind speed to leave the roost. Key Words: Rhinolophus hipposideros, paternal care, roost use, Portugal. ResumenCasi todos los murciélagos tienen hábitos nocturnos pero los patrones de actividad durante la noche pueden variar entre las especies y dentro de la misma especie en diferentes lugares. El murciélago pequeño de herradura Rhinolophus hipposideros (Bechstein, 1800) sufrió un severo declive en muchos países de su área de distribución, incluyendo Portugal. En este estudio, se pretende describir el comportamiento de refugio durante la primavera, verano y otoño de una de las colonias de cría más grande de R. hipposideros en Portugal. Asimismo, se analizó la ocupación y los patrones de actividad en el refugio, el periodo de nacimientos, y el comportamiento postnatal. También se comprobó el efecto de los factores ambientales en el uso del refugio. Toda la información se obtuvo a partir del análisis de los videos grabados en el interior del refugio. Los datos climáticos se obtuvieron mediante una estación meteorológica. Se observó que el refugio tiene una mayor ocupación durante el mes de agosto y que en octubre sólo se ocupa durante la noche. Las hembras dan a luz entre finales de mayo y principios de junio, y en agosto los juveniles parecen ser independientes e indistinguibles de los adultos. Esta colonia presenta un patrón bimodal de actividad que parece estar relacionado con el atardecer y amanecer. Nuestros resultados también indican que esta colonia de murciélagos prefiere altas temperaturas pero baja humedad y una cierta velocidad del viento para abandonar el refugio.

“…Bats use roost sites for such activities as copulation, hibernation, and maternal care, and spend over half of their lifetime inside the roost (Kunz 1982;Altringham 1996). Roost-site availability is one of the limiting factors affecting the distribution and abundance of temperate bats (Humphrey 1975;Kunz 1982).…”

Day roosts and roost-site selection of Ikonnikov's whiskered bat, Myotis ikonnikovi, in Nikko, Japan

Abstract. Roost-site preferences of the tree-roosting bat (Myotis ikonnikovi) were examined using radio telemetry. Field investigations were conducted in Nikko, Tochigi, Japan, during the summers of 2001 and 2002. We radio-tracked nine bats, and 16 roost trees were found. Bats actively selected snags, more decayed stages of snags and larger stem diameters, compared to available trees in roost plots and trees in random plots. Bats changed roosts every 1 or 2 days. Low roost fidelity indicated that M. ikonnikovi needed many roosting trees. Of these roost trees, six were determined roost-sites: Four roosts were located under bark, one was in a small cavity of a broken stem, and one was in a narrow space between a climbing vine (liana) and a trunk. To improve conservation of M. ikonnikovi, a substantial number of snags and large trees must be preserved in the bat's habitat.
