With the help of 200 citizen scientists, Daniel Lewanzik and team found four ways to turn cities bat-friendly: 1) switch off light, 2) plant parks, 3) create ponds, and 4) connect habitats. Check out the paper at https://www.sciencedirect.com/science/article/pii/S0269749121023678

The batlab is part of the Department Evolutionary Ecology at the Leibniz-IZW (www.izw-berlin.de). We are contributing to the institute's mission by doing "Research for Wildlife Conservation".
The IZW batlab of PD Dr. Christian Voigt consists of about 20 people, including postdocs, PhD student, master students and scientific and technical staff.
We are not only doing top-end research for the conservation of wildlife species, we also work hard to communicate our findings to relevant stakeholders and the general public.

Bat-mediated trophic effects on farmland insect diversity 0. Brief expected profile of PhD student Candidates must have a MSc in Ecology or similar field, with profound experience in behavioral ecology, analysis of acoustic parameters, spatial tracking of animals and/or field-based experimental approaches. Additionally, candidates should have a profound knowledge in multivariate statistics, specifically in the use of R, should be fluent in English (both speaking and writing) and have a driver license for field work. Knowledge of German is beneficial, but not mandatory, since field work takes place at remote place in Germany.
Short Abstract: By consuming other animals, predators may influence the distribution and diversity of their prey. These top-down trophic effects may depend on predator-specific movement patterns, which vary in space and time following, e.g., resource and competitor distribution. Insect predators, such as bats, may affect the abundance and distribution of insects, offering potentially ecosystem services. Using high resolution spatial tracking of bats and automated ultrasonic recording of bats, we plan to quantify the link between bat movements and their top-down trophic effect on farmland insect diversity. To this end, we will allow (control) or prevent (exclosure) bats the access to a set of plots with a pre-defined plant composition, and then measure the trophic effect of bats by comparing arthropod diversity and abundance between control plots and exclosures (Maas et al. 2019). By linking bat movements, and thus bat presence, to landscape features, we will model the spatial distribution of bat-mediated ecosystem services on farmland.
Background and previous work: Overall, we aim at understanding biodiversity patterns that are related to the spatial behavior of predators (Schlägel et al. 2020). In P05, we focus specifically on bat movements and their insect prey within the conceptual framework of the extended movement ecology paradigm (Nathan et al. 2008, Jeltsch et al. 2013). In collaboration with other members of the RTG Biomove, we have established a joint study site, the AgroScapeLabs, north of Berlin. There, we have tracked successfully bats with the cutting-edge technology of the Atlas-System (Weiser et al. 2015, Toledo et al. 2020). The Atlas system is a high-throughput VHF system that automatically triangulates the position of tagged animals based on signal delay at several receiving antenna stations. Encoded VHF signals allow the simultaneous tracking of several animals at high temporal and spatial resolution. Our earlier tracking studies have shown that common noctule bats prefer certain habitats when foraging above farmland (Roeleke et al. 2016, 2018, 2020). Based on acoustic surveys, we documented that local bat activity varied between species and depended largely on landscape features, such as edge structures, ponds and the intensity of farmland practice (Heim et al. 2017, 2018). Further, using metabarcoding of insect DNA in fecal pellets of bats, we have established a good understanding about which insect prey bats are consuming when foraging above farmland throughout the season.
Objectives/Aims: The proposed study will combine the study of animal movements with those of trophic interactions on a landscape scale level. Specifically, we will address the following questions: a) What is the effect of foraging bats on insect abundance and diversity? b) Does insect-feeding by bats alter the insect-mediated ecosystem services (pollination) and disservices (herbivory)? c) Do landscape features within relatively homogenous farmland landscapes modify the top-down trophic effects of bats? 4. Outline work program We plan to measure the activity of syntopic bat species at experimental field exclosures based on automated ultrasonic detectors. This will allow us to quantify the species-specific effect of bats on local insect diversity. By quantifying the level of insect herbivory and seed production at experimental field exclosures, we will estimate how bat predation influences insect-mediated ecosystem services. Lastly, we will tag dozens of bats of syntopic species with miniaturized tags to estimate the spatial behavior of bats in our experimental area. By connecting information on how syntopic bats forage in response to landscape features, we envision to assess the spatial heterogeneity of bat-mediated trophic effects on the landscape level.

This e-book reviews the current knowledge on why many bats are threatened worldwide and how to protect bats in a rapidly changing world. Bats comprise more than 1.400 species, are relevant ecosystem service providers, yet many species are at risk. This book is a key publication for bat experts, conservationists and students.
