Biology of Myotis thysanodes and M. lucifugus (Chiroptera: Vespertilionidae)—III. Metabolism, heart rate, breathing rate, evaporative water loss and general energetics

Spatial characterization of colonies of the flying fox bat, a carrier of Nipah Virus in Thailand

“…The Department of Environment of the Australian government also reported that flying foxes sites were usually found close to water [ 10 ]. Several studies indicated that bats lose a significant amount of water while they are roosting, especially under conditions of low relative humidity and high temperature [ 51 - 53 ]. Furthermore, lactating females need more frequent drinking than non-reproductive females [ 54 ].…”

Temporal resource partitioning by bats at water holes

“…Previous studies that documented high levels of evaporative water loss in insectivorous bat species under laboratory conditions of high temperature and low humidity (Studier, 1970; Studier et al , 1970; O'Farrell et al , 1971; Studier & O'Farrell, 1976; Webb, 1995; Webb et al , 1995) clearly indicate that bats emerging from diurnal roosts, especially in hot, arid environments, would be motivated to drink at nearby water holes to replenish diurnal losses. These data were instrumental in us testing the hypothesis of resource partitioning at water holes proximate to roost sites where large numbers of bats congregate to drink at small (<2 m diameter) water holes.…”

Daily torpor reduces the energetic consequences of microhabitat selection for a widespread bat

“…To quantify energy expenditure in bats, we combined published estimates of metabolic rates of fringed myotis as a function of temperature (Studier & O'Farrell, 1976 ) and the linear model of the influence of ambient temperature on daily torpor use to simulate the influence of temperature within microhabitats on energy expenditure. Specifically, we simulated minute‐by‐minute energy expenditure by bats in each used microhabitat between 4:45 AM and 9:00 PM (typical entry and exit times for bats in our study) on each day over the duration of our study period.…”
