“…The absence of any discernible population structure within these samples may reflect the movement of bats among roosts, especially in mixed species overwintering roosts (Rehak & Gaisler ; Smirnov et al . ). Although mark–recapture studies with Myotis myotis reveal female philopatry (Horáček ; Berková et al .…”

Host association drives genetic divergence in the bed bug, Cimex lectularius

Genetic differentiation may exist among sympatric populations of a species due to long-term associations with alternative hosts (i.e. host-associated differentiation). While host-associated differentiation has been documented in several phytophagus insects, there are far fewer cases known in animal parasites. The bed bug, Cimex lectularius, a wingless insect, represents a potential model organism for elucidating the processes involved in host-associated differentiation in animal parasites with relatively limited mobility. In conjunction with the expansion of modern humans from Africa into Eurasia, it has been speculated that bed bugs extended their host range from bats to humans in their shared cave domiciles throughout Eurasia. C. lectularius that associate with humans have a cosmopolitan distribution, whereas those associated with bats occur across Europe, often in human-built structures. We assessed genetic structure and gene flow within and among populations collected in association with each host using mtDNA, microsatellite loci and knock-down resistance gene variants. Both nuclear and mitochondrial data support a lack of significant contemporary gene flow between host-specific populations. Within locations human-associated bed bug populations exhibit limited genetic diversity and elevated levels of inbreeding, likely due to human-mediated movement, infrequent additional introduction events per infestation, and pest control. In contrast, populations within bat roosts exhibit higher genetic diversity and lower levels of relatedness, suggesting populations are stable with temporal fluctuations due to host dispersal and bug mortality. In concert with previously published evidence of morphological and behavioural differentiation, the genetic data presented here suggest C. lectularius is currently undergoing lineage divergence through host association.

“…Bat observers use torches, binoculars and sometimes mirrors (to look behind corners) to search for bats (e.g. Mitchell‐Jones & McLeish 1999, Smirnov et al 2007). In the European census, bats are never handled for identification and most bat observers try to avoid creating non‐tactile stimuli.…”

Keeping bats cool in the winter: hibernating bats and their exposure to ‘hot’ incandescent lamplight

In order to monitor bat population trends, an annual census is performed of all known underground hibernacula in Europe. During these censuses, bats are sometimes found to show signs of arousal, presumably from non-tactile stimuli caused by the observer, e.g. air currents, sound, light or an increase in temperature. We assume that heat and/or light from a torch can play a role in awaking hibernating bats. Observers use different light sources, which produce different amounts of heat. We experimentally tested the heat produced by three commonly used torches: two incandescent torches (krypton and halogen) and one LED torch. We performed the experiment on 28 January 2007 in an old brick kiln in Windesheim (Overijssel Province, the Netherlands), which is used by hibernating bats. The results show that temperatures in a crevice significantly increased when using the 'hot' incandescent torch types. The effect of these torches on both air and surface temperature was significant after both 10 and 30 seconds. Under the assumption that an increase of the ambient temperature by 58C or more can cause a bat to arouse from torpor, we conclude that using 'hot' torches such as incandescent (halogen) lights poses a risk to the animals under study. To minimise heat disturbance from light sources, we recommend LED torches as the best available alternative.

“…Rare findings are due to the low abundance and sporadic distribution of this species (Smirnov 2013). Natterer's Bat inhabits deciduous and mixed forests, has a sedentary lifestyle and hibernates in deep crevices or underground spaces (Smirnov et al 2007(Smirnov et al , 2008Smirnov & Vekhnik 2009, 2011, 2014. Summer habitats are closely related with trees and are confined to regions with expressed karstic landforms (Ilyin & Smirnov 2000).…”

New records of Nyctalus leisleri (Kuhl, 1817) and Myotis nattereri (Kuhl, 1817) (Mammalia: Chiroptera: Vespertilionidae) from National Park “Smolny” and its surroundings, Republic of Mordovia

Protected areas in the Republic of Mordovia are still poorly studied in relation to bats. Our research of the bat fauna in the National Park “Smolny”, Republic of Mordovia was conducted in 2018‒2020. A total of 573 bats of nine species belonging to the family Vespertilionidae were captured and studied. Nyctalus leisleri and Myotis nattereri were caught here for the first time. Three new sites of two rare bat species were discovered. The list of bats in the National Park “Smolny” currently includes 10 species.
