- Abstract: Climate change is among the key anthropogenic factors affecting species' distribution, with important consequences for conservation. However, little is known concerning the consequences of distributional changes on community‐level interactions, and responses by generalist species might have many ecological implications in terms of novel interactions with resident species. In this study, we applied Ecological Niche Models and niche analysis to three generalist bat species, Hypsugo savii, Pipistrellus kuhlii, and Pipistrellus pipistrellus, which share similar ecological traits and are sympatric in parts of their ranges. Our aims were to investigate how predicted climate change will affect species' distribution and to analyse the degree of climatic niche overlap between the three species, in both the current and the future scenarios (2050 and 2070; Representative Concentration Pathways 4.5 and 8.5). Temperatures were the most important predictors influencing species' range expansion in future. According to our models, Pipistrellus kuhlii and Hypsugo savii may expand their geographic ranges towards northern latitudes, whereas the geographic range of the less thermophilous Pipistrellus will shift northwards, resulting in it losing the southern portion in Europe. The already considerable degree of climatic niche overlap between the three species will increase further in future. On the basis of our findings, within the new areas potentially colonised by all three speciesAbstract: Climate change is among the key anthropogenic factors affecting species' distribution, with important consequences for conservation.

On the basis of our findings, within the new areas potentially colonised by all three species in future, alterations in community‐level balance might occur, bringing about effects that are only partially predictable. In view of this, we highlight the need for further research and improved monitoring of bat communities in areas that are predicted to be particularly vulnerable to climate change. Abstract : We used Species Distribution Models to predict changes in the geographic distribution of three common European bat species, Hypsugo savii (above), Pipistrellus kuhlii (middle), and Pipistrellus pipistrellus (below), in response to climate change. We showed that while the first two species are predicted to expand their range, as expected due to their thermophilic habits, Pipistrellus pipistrellus will experience a range contraction in the southernmost portion of its range. We conclude that in the regions affected by such changes, community‐level balance might be altered, leading to effects that are only partially predictable. Abstract : RESUMEN EN ESPAÑOL El cambio climático es uno de los factores antropogénicos clave que influyen sobre la distribución de las especies, con consecuencias importantes para la conservación. Sin embargo, poco se sabe sobre las implicaciones ecológicas de los cambios de distribución en las interacciones a nivel de comunidad, y de las respuestas que las especies generalistas podrían tener en términos de interacciones novedosas con especies residentes. En este estudio, aplicamos los Modelos de Nicho Ecológico y el análisis de nicho a tres especies de murciélagos generalistas, Hypsugo savii, Pipistrellus kuhlii y Pipistrellus pipistrellus, que comparten características ecológicas similares y son simpátricas en algunas de sus áreas de distribución. Nuestros objetivos eran investigar cómo el cambio climático afectará la distribución de dichas especies y analizar el grado de superposición de los nichos climáticos entre las tres especies, tanto en el escenario actual como en el futuro (2050 y 2070; Representative Concentration Pathways 4.5 y 8.5). Las temperaturas fueron los predictores más importantes que podrían influir en el rango de expansión de dichas especies en el futuro. Según nuestros modelos, Pipistrellus kuhlii e Hypsugo savii podrían expandir sus rangos geográficos hacia las latitudes del norte, mientras que el rango geográfico del Pipistrellus pipistrellus, el cual es menos termófilo, se desplazará hacia el norte perdiendo así la porción sur de su rango geográfico actual. Por otro parte, el grado de superposición de nichos climáticos entre las tres especies, ya considerable en el presente, aumentará aún más en el futuro. Sobre la base de nuestros hallazgos, dentro de las nuevas áreas potencialmente colonizadas por las tres especies en el futuro, podrían ocurrir alteraciones en el equilibrio a nivel de comunidad, provocando efectos que son solo parcialmente predecibles. Por lo anterior, destacamos la necesidad de realizar más investigaciones y mejorar el monitoreo de las comunidades de murciélagos en áreas que se prevé sean particularmente vulnerables al cambio climático. … (more)
