Age And Sex

The influence of behaviour on host-parasite dynamics has theoretical support but few empirical studies have examined this influence for wild-captured hosts, especially in colonial species, which are thought to face generally high risk of exposure. Behavioural tendencies of hosts in novel environments could mediate host exposure. We tested the hypothesis that behavioural tendencies of hosts, and host sex and age, correlate with prevalence and intensity of ectoparasites in a gregarious mammal, the little brown bat (Myotis lucifugus). We also tested whether relationships between host behaviour and parasite prevalence and intensity would vary between taxa of ectoparasites which differ in host-seeking behaviour. We predicted that individual hosts displaying active and explorative behaviours would have higher prevalence and intensity of parasites that depend on physical contact among hosts for transmission (mites) but that host behaviour would not influence prevalence and intensity of mobile ectoparasites with active host-seeking behaviour (fleas). We recorded behavioural responses of wild-captured bats in a novel-environment test and then sampled each individual for ectoparasites. After accounting for age and sex we found mixed support for our hypotheses in some but not all demographics. More active adult and young of the year (YOY) males were more likely to host mites while more active adult and YOY females were less likely to host fleas. Our results highlight possible differences in the influence of host and parasite behaviour on parasite transmission dynamics for colonial compared to non-colonial species and have conservation implications for understanding pathogen transmission in bat white-nose syndrome and other wildlife diseases.

A comparison of the activity of the little brown bat (Myotis lucifugus) over calm pools and fast-flowing riffles was performed in southwestern Alberta. Bat activity was assessed by monitoring echolocation calls using ultrasonic detectors. Activity was higher over pools than riffles. This could be due to differences in prey abundance or accessibility in the two habitats. Alternatively, water noise at turbulent sites may interfere with the bats' echolocation abilities. Sticky traps were used to assess prey abundance, and water noise was recorded for intensity–frequency analysis. Insect abundance at the height where the bats flew (< 1 m above the water) did not differ between sites, but insects close to or at water level at calm pools may be more accessible than at fast-flowing riffles. Further, water noise at riffles may decrease the efficiency with which bats detect targets.

Temperature Time

Daily and seasonal activity budgets of adult female eastern pipistrelle bats, Pipistrellus subflavus, were quantified at a maternity colony in eastern Massachusetts. Ambient and roost temperatures were recorded. Activities of roosting bats were monitored using an infrared-sensitive video camera. Scan sampling was used to analyze video records taken at weekly intervals from mid-May to late July 1989. Analysis of day-roosting indicates that adult females spend an average of 77% of their time at rest, 16% alert, 7% grooming, and < 1% crawling. Bats were most active immediately following their morning return to the day-roost and just prior to their departure at dusk. Periodic bouts of activity throughout the day were usually associated with urination and (or) defecation, mother–pup interactions, and movements in response to changes in roost temperature. Females were significantly more active in mortise roosts than when roosting on the open ridgepole, probably because fluctuations in temperature in mortises were smaller. As the season progressed, the overall time that bats spent resting decreased from 86 to 70%, whereas time spent alert increased from 9 to 24%; weekly fluctuations in the incidence of grooming and crawling showed no consistent seasonal trends. Roost temperature, time of day, and date explained significant amounts of variation in both daily and seasonal activity budgets. Females rested significantly less and were more alert after young were born than before, although time spent grooming and crawling did not differ significantly between the pre- and post-partum periods. Our findings for P. subflavus generally corroborate activity budgets previously reported for the little brown bat (Myotis lucifugus).

Bat Guano

This study characterizes the composition, structure, and dynamics of arthropod communities associated with bat guano deposits in buildings. Guano beneath three summer roosts of the little brown bat (Myotis lucifugus) in southern New Hampshire was sampled over a 1-year period.Twelve arthropod species are reported of which most are cosmopolitan associates of dried organic matter and stored products. Included are psocopterans, beetles, mites, hemipterans, a flea, and a pseudoscorpion. These taxa function as fungivores, sarcophages, predators, and ectoparasites.These simple arthropod communities exploit a seasonally rich resource produced by roosting bats. Nycteriglyphine mites were the first free-living colonizers of fresh guano deposits and were the most numerous arthropods throughout the year. Older guano deposits and those with the most diverse resource base generally supported the greatest number of species.Seasonal changes in communities included the presence of fleas only when bats were present, a greater number but lower diversity of other arthropod species when bats were present, and a more equitable distribution and abundance of species when bats were absent. Fresh, wet guano supported higher densities of fungivorous mites and flea larvae than did older, drier guano.
