“…Eptesicus serotinus and Vespertilio murinus were con rmed only from single locations. Nyctalus leisleri and Eptesicus nilssoni were not con rmed during research in the city centre (Kohyt et al 2021). Research in Brno (Gaisler et al 1998) showed that the highest N. noctula activity was recorded in riverine environments, while E. serotinus was found the least frequently in this environment (it was most common in the old outskirts .…”

Different bat species adapt to urban environments with varying efficiency. Urban watercourses may promote bats’ presence in the city but also, because of improper management, may become an impassable barrier. This work evaluated the bats’ presence in different urban riverside environments during the vegetation season. Bats’ activity was recorded in Cracow on the main river Vistula and its tributary Rudawa. Our results showed that long-range echolocators were represented mainly by Nyctalus noctula. Their activity peak occurred in late summer in open habitats with high anthropopressure levels, and at least part of the population is present year-round in the city. Recently reported from Cracow: Hypsugo savii and Pipistrellus kuhlii were confirmed in the medium-range echolocators. The high occurrence of P. pygmeus with a relatively low P. pipistrellus was noteworthy and is probably a result of the low competitiveness of the latter in the presence of P. kuhlii. Two spring and late summer activity peaks on different rivers suggest different migration corridors to and from hibernacula. However, the autumn activity in the city centre may also indicate partial hibernation in the old town. The activity peak of short-range echolocators occurred in spring, as expected - mainly in a narrow riverbed and low anthropopressure environments. Although, ambiguous spring and late summer activity in the open with the highest anthropopressure environment may result from the rapidly progressing synurbization of M. daubentonii. Our results indicate the need to monitor the bat adaptation process to the cities in the context of dynamic climatic and environmental changes.

“…Yearly and seasonal patterns in temperature and precipitation, referred to in biogeographic modelling as bioclimatic factors or predictors, are known to influence behaviour and life history in bats around the world (Conenna et al., 2019 ; Gorman et al., 2021 ; Kohyt et al., 2021 ; Weinberg et al., 2022 ). To capture these conditions and test the hypothesis that macroclimatic effects can determine occurrence of bats, the 19 standard current bioclimatic predictor variables were sourced at 2.5 arc‐minute resolution from the WorldClim v2.1 database for the period of 1970–2000 (Fick & Hijmans, 2017 ).…”

Climate change majorly impacts biodiversity in diverse regions across the world, including South Asia, a megadiverse area with heterogeneous climatic and vegetation regions. However, climate impacts on bats in this region are not well‐studied, and it is unclear whether climate effects will follow patterns predicted in other regions. We address this by assessing projected near‐future changes in climatically suitable areas for 110 bat species from South Asia. We used ensemble ecological niche modelling with four algorithms (random forests, artificial neural networks, multivariate adaptive regression splines and maximum entropy) to define climatically suitable areas under current conditions (1970–2000). We then extrapolated near future (2041–2060) suitable areas under four projected scenarios (combining two global climate models and two shared socioeconomic pathways, SSP2: middle‐of‐the‐road and SSP5: fossil‐fuelled development). Projected future changes in suitable areas varied across species, with most species predicted to retain most of the current area or lose small amounts. When shifts occurred due to projected climate change, new areas were generally northward of current suitable areas. Suitability hotspots, defined as regions suitable for >30% of species, were generally predicted to become smaller and more fragmented. Overall, climate change in the near future may not lead to dramatic shifts in the distribution of bat species in South Asia, but local hotspots of biodiversity may be lost. Our results offer insight into climate change effects in less studied areas and can inform conservation planning, motivating reappraisals of conservation priorities and strategies for bats in South Asia.

Aim We assessed the projected changes in climatically suitable areas for South Asian bats from current conditions (1970-2000) to the near future (2041-2060) in response to climate change scenarios, identifying hotspots of climatic suitability, and measuring the direction and zero-cost distance between climatically suitable areas in the present and the near future. Location South Asia Time period Present day and near future (2050) Major taxa studied South Asian bats Methods We used ensemble ecological niche modelling for 110 selected South Asian bat species with four algorithms (random forests, artificial neural networks, multivariate adaptive regression splines, and maximum entropy) to define climatically suitable areas under current conditions (1970–2000). We then predicted future (2041–2060) climatically suitable areas under four projected scenarios (combining two global climate models and two shared socioeconomic pathways, SSP2: middle-of-the-road and SSP5: fossil-fuelled development). Results Predicted future changes in climatic suitable areas varied across species but the majority were predicted to retain most of the current area or have small losses. When shifts occurred due to projected climate change, new areas were generally at higher latitudes (northward shift). Climatically suitable hotspots (suitable for >30% of species) were generally predicted to become smaller and more fragmented. Main conclusions Overall, climate change in the near future may not lead to dramatic shifts in the distribution of bat species in South Asia, but local hotspots of biodiversity may be lost. Our results offer insight into climate change effects in less studied areas and can inform conservation planning, motivating reappraisals of conservation priorities and strategies for bats in South Asia.
