Population dynamics of little brown bats (Myotis lucifugus) at summer roosts: apparent survival, fidelity, abundance, and the influence of winter conditions
<ol> <li>White-nose syndrome (WNS) has caused the death of millions of bats, but the impacts have been more difficult to identify in western North America. Understanding how WNS, or other threats, impact western bats may require monitoring other roosts, such as maternity roosts and night roosts, where bats aggregate in large numbers.</li> <li>Little brown bats (<em>Myotis lucifugus</em>) are experiencing some of the greatest declines from WNS. Estimating survival and understanding population dynamics can provide valuable data for assessing population declines and informing conservation efforts.</li> <li>We conducted a 5-year mark-recapture study of two <em>M. lucifugus</em> roosts in Colorado. We used the robust design model to estimate apparent survival, fidelity, and abundance to understand population dynamics, and environmental covariates to understand how summer and winter weather conditions impact adult female survival. We compared the fidelity and capture probability of <em>M. lucifugus</em> between colonies to understand how bats use such roosts.</li> <li>Overwinter survival increased with the number of days with temperatures below freezing (β > 0.100, SE = 0.003), and decreased with the number of days with snow cover (β < -0.40, SE < 0.13). Adult female fidelity was higher at one maternity roost than the other. Overwinter and oversummer adult female survival were high (>0.90), and based on survival estimates and fungal-swabbing results we believe these populations have yet to experience WNS.</li> <li>Recapture of <em>M. lucifugus</em> using antennas that continuously read passive integrated transponder tags allows rigorous estimation of bat population parameters that can elucidate trends in abundance and changes in survival. Monitoring populations at summer roosts can provide unique population ecology data that monitoring hibernacula alone may not. Because few adult males are captured at maternity colonies, and juvenile males have low fidelity, additional effort should focus on understanding male <em>M. lucifugus </em>population dynamics.</li> </ol>
FIG. 2 in Postnatal variation in ectoparasite (Spinturnix emarginata) load in neonates of Geoffroy's bat (Myotis emarginatus): how fast do young bats become infested with ectoparasites?
FIG. 2. Relationship between mite load and body mass in male (Ì) and female (u) neonates of M. emarginatus measured in nine sampling occasions in the Kerend cave, western Iran
FIG. 1 in Postnatal variation in ectoparasite (Spinturnix emarginata) load in neonates of Geoffroy's bat (Myotis emarginatus): how fast do young bats become infested with ectoparasites?
FIG. 1. Average and SE of ectoparasite load in nine sampling occasions on neonates (■) and lactating female M. emarginatus (●) during the postnatal period in the Kerend cave in western Iran. The number of mites and bats is shown in Table 1. The drawn lines show some tendencies although they are not statistically significant. Sampling occasions range from day 1 (June 3) till day 43 (July 15)
FIG. 1. Myotis myotis and M in A potent anti-inflammatory response in bat macrophages may be linked to extended longevity and viral tolerance
FIG. 1. Myotis myotis and M. musculus macrophages present differential response to LPS and Poly(I:C) challenge. Change in gene expression of A — IFN-β, B — IL-1β, C — TNF, D — Il-10 in response to LPS and Poly(I:C) treatment at 1, 4 and 24 hr time points are presented as changes in delta Ct values normalized to actin-β. Ratios of the fold induction of anti-inflammatory Il-10 to proinflammatory TNF (E) and Il-1β (F) are also presented. G — Literature derived Il-10/TNF ratios for other mammals. H — NO generated by stimulated M. myotis and mouse macrophages. Bars represent the mean of two experimental repeats ± SEM. Presented P -values indicate the significance of the difference between species from analysis of variance (ANOVA)
Influence of ambient temperature on the phenology of the greater mouse-eared bat (Myotis myotis)
<p>In order to assess the consequences of climate change and evaluate its impacts on wildlife, it is essential to do so on a species-specific level. It is assumed that changes in the ambient temperature influence energy consumption as well as food availability and thus foraging behaviour, reproduction, survival and therefore population dynamics in bats. Based on this assumption, the present study aims to gain insights into the roosting and breeding behaviour of the greater mouse-eared bat (<em>Myotis myotis</em>) in relation to changes of the ambient temperature. For this purpose, we investigated the effect of ambient temperature on the phenology of the greater mouse-eared bat by using activity data of the bats collected using light barriers at the maternity roosts. The light barrier used in this study is a system that detects the interruption of two light beams, e.g. by a flying bat, and displays it as an electrical signal. The investigations have shown that (1) the higher the winter temperatures, the earlier the greater mouse-eared bats returned to the roosts to form the maternity colony; however, this was only true for ambient temperatures below 0.5 °C, (2) birth season started earlier at higher spring temperatures, and (3) the dissolution of maternity roosts occurred earlier with an earlier birth season and at higher ambient temperatures during lactation. The results revealed that ambient temperature has an influence on the phenology of the greater mouse-eared bat. This study highlights that in order to understand the impact of climate change on biodiversity, it is necessary to investigate in detail effects on a species-specific level and also to consider direct and indirect effects of ambient temperature on different life history stages.</p>
