Vespertilionid Bats

The durations of the periods of hibernation of the big brown bat (Eptesicus fuscus), little brown bat (Myotis lucifugus), and eastern pipistrelle (Pipistrellus subflavus) under natural conditions were determined by following intracave movements through two winter seasons in two Missouri caves. Average durations of periods of hibernation were similar for all three species (10–20 days) over a range of temperatures. Maximum durations of periods of hibernation determined were as follows: E. fuscus, 72 days; P. subflavus, 111 days (?); M. lucifugus, 83 days. Variability in the durations of the period of hibernation was much greater for P. subflavus and may be attributable to a lack of movement after arousal or the inability of the observer to discern movement between periods of hibernation. The frequency of arousal was determined to be statistically temperature dependent for M. lucifugus, but not for E. fuscus or P. subflavus, probably because of insufficient data.

Vespertilionid Bats

Variation in the duration of the period of hibernation of three species of vespertilionid bats under laboratory conditions was great. Durations of the period of hibernation of the big brown bat (Eptesicus fuscus) ranged from less than a day to 908 h (37.8 days) at 5 °C and to 1227 h (51.1 days) at 2 °C. Those for the little brown bat (Myotis lucifugus) ranged from less than a day to 1398 h (58.2 days) at 5 °C and to 1827 h (76.1 days) at 2 °C. Those for Pipistrellus subjlavus (eastern pipistrelle) ranged from less than a day to 649 h (27.0 days) at 5 °C and to 864 h (36.0 days) at 2 °C. It is proposed that the tendency toward great variation is an inherent characteristic of the bats and is not a laboratory-induced artifact. Despite great variation, a temperature dependency of the frequency of arousal was demonstrated for E. fuscus, P. subjlavus, and M. lucifugus. Slopes of regression for E. fuscus, P. subflavus, and M. lucifugus derived from semilogarithmic plots of durations of the period of hibernation versus temperature are similar to each other and to those of hibernating ground squirrels. The regulating effect of temperature upon hibernation suggests that the frequency of arousal is controlled metabolically.

Incremental Lines

Determination of age of several species of vespertilionid bats by counting incremental lines in dentine, cementum, and peridontal bone is described. The technique was most effective for aging Eptesicus fuscus and Lasionycteris noctivagans and less so for Myotis lucifugus. Incremental lines in specimens of Lasiurus cinereus and Lasiurus borealis were clearly defined, while those in a Myotis californicus were not. Longevity of E. fuscus and longevity and apparent age structure of M. lucifugus agree with the findings of published banding studies.

Eurema nilgiriensis Yata, 1990, the Nilgiri grass yellow, was described from Nilgiris in southern India. There are not many published records of this species since its original description, and it was presumed to be a high-elevation endemic species restricted to its type locality. Based on the external morphology (wing patterns) as well as the male genitalia, the first confirmed records of the species from Agasthyamalais and Kodagu in the southern Western Ghats, is provided here. This report is a significant range extension for the species outside the Nilgiris, its type locality. Ecological data pertaining to this species as well as the field identification key to all known Eurema of Western Ghats are also presented.

Abstract Background White-nose Syndrome (WNS) has reduced the abundance of many bat species within the United States’ Mid-Atlantic region. To determine changes within the National Park Service National Capital Region (NCR) bat communities, we surveyed the area with mist netting and active acoustic sampling (2016–2018) and compared findings to pre-WNS (2003–2004) data. Results The results indicated the continued presence of the threatened Myotis septentrionalis (Northern Long-eared bat) and species of conservation concern, including Perimyotis subflavus (Tri-colored bat), Myotis leibii (Eastern Small-footed bat) and Myotis lucifugus (Little Brown bat). However, we documented a significant reduction in the abundance and distribution of M. lucifugus and P. subflavus, a decrease in the distribution of M. septentrionalis, and an increase in the abundance of Eptesicus fuscus (Big Brown bat). Conclusions Documented post-WNS M. septentrionalis recruitment suggests that portions of the NCR may be important bat conservation areas. Decreases in distribution and abundance of P. subflavus and M. lucifugus indicate probable extirpation from many previously occupied portions of the region.
