AB  - Monitoring programmes provide extremely helpful information to understand population dynamics and make effective management decisions, but they are usually constrained by methodological and economical limitations. Advances in bioacoustic technologies offer new opportunities for bat monitoring. In this study, we present a method to monitor small and medium-sized cave-dwelling bat colonies using low-cost AudioMoth passive acoustic recorders. We develop a method to convert bat passes, a measure of acoustic activity, to an estimated number of bats in the roost. To do so, we took audio-visual recordings of five Miniopterus schreibersii colonies emerging from their roosts over 25 nights. We compared the accuracy of the estimates when using site-specific acoustic data against a combined global dataset and examined the influence of the detector position on the estimates. Site-specific acoustic datasets recorded at the cave entrance showed to be adequate to estimate roost bat numbers. In addition, we acoustically monitored one cave during three months of continuous sampling to test our protocol and compared the resulting data with historical datasets of roost occupancy. This method provides a low-cost, non-invasive and simple approach to monitor seasonal and inter-year roost dynamics that can easily be implemented in long-term monitoring programmes and citizen science projects.

AB  - Bats are well known for playing an important role in several ecosystem services such as arthropod population control, insect pest suppression in agricultural systems and vector disease control, but also for acting as ecological indicators. Their population dynamics are strongly linked to environmental variations and, in some cases, reflect the health status of ecosystems. Hence, some species have an excellent potential as ecological indicators due to their sensitivity to ecosystem changes. Despite the general decrease of many bat populations worldwide and the recent upsurge in the use of autonomous acoustic detectors, the acoustic monitoring of bat assemblages is still an emerging field in bat research and conservation. Probably due to a general lack of methodological standards and the lack of common ecological indices, few long-term bat acoustic monitoring programs are currently active and data is rarely shared and compared between regions. In this study we propose and adapt a set of different ecological indices that can be used in acoustic surveys designed to detect changes in bat diversity, activity and assemblage composition, all of which can be linked to species’ climatic and habitat-related preferences. Using a dataset collected during three years of bat monitoring in Catalonia (NE Iberian Peninsula), we used three traditional indices (richness, activity and Shannon diversity) and developed four new ecological indices (Community Thermal Index, Community Precipitation Index, Community Openness Index and Community Specialization Index) that enabled us to study bat communities and compare them at different spatial and temporal scales. Here, we demonstrate the applicability of these indices in bat monitoring programs. We also provide a consistent tool for generating easy-to-interpret ecological indices when monitoring the short- and long-term responses of bats under the current scenario of global change. Using standardized protocols and robust ecological indices enables studies and datasets to be compared, which in turn promotes the development of proper management and conservation measures via international cooperation.
