Worldwide Soundscapes: A Synthesis of Passive Acoustic Monitoring Across Realms
Darras, Kevin F. A.; Rountree, Rodney A.; Van Wilgenburg, Steven L.; Cord, Anna F.; Pitz, Frederik; Chen, Youfang; Dong, Lijun; Rocquencourt, AgnèsAim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. ...
Secondary forest buffers the effects of fragmentation on aerial insectivorous b...
Rowley, Sarah; López-Baucells, Adrià; Rocha, Ricardo; Bobrowiec, Paulo E. D.; Meyer, Christoph F. J.Passive forest restoration can buffer the effects of habitat loss on biodiversity. We acoustically surveyed aerial insectivorous bats in a whole-ecosystem fragmentation experiment in the Brazilian Amazon over a 2-year period, across 33 sites, comprising continuous old-growth forest, remnant fragments, and regenerating secondary forest matrix. We analyzed the activity of 10 species/sonotypes to investigate occup...
Current Knowledge and Conservation of the Wild Mammals of the Gulf of Guinea Oc...
Rainho, Ana; Meyer, Christoph F. J.; Thorsteinsdottir, Solveig; Juste, Javier; M. Palmeirim, JorgeOceanic islands are usually difficult for mammals to colonize; consequently, the native mammal fauna is typically species-poor, often consisting of just a few species of bats. The oceanic islands of the Gulf of Guinea are no exception to this pattern. Still, the known mammal richness is relatively high for the small size of the islands. Out of a total of 13 native species, including 11 bats and 2 shrews, at lea...
Interplay between local and landscape-scale effects on the taxonomic, functiona...
López-Baucells, Adrià; Rowley, Sarah; Rocha, Ricardo; Bobrowiec, Paulo E. D.; M. Palmeirim, Jorge; Farneda, Fábio Z.; Meyer, Christoph F. J.Context Human-modified landscapes are globally ubiquitous. It is critical to understand how habitat loss and fragmentation impact biodiversity from both a local habitat context and landscape-scale perspective to inform land management and conservation strategies. Objectives We used an experimentally fragmented landscape in the Brazilian Amazon to investigate variation in aerial insectivorous bat diversity in re...
Kin structure and roost fidelity in greater noctule bats
Santos, João Dourado; Meyer, Christoph F. J.; Ibáñez, Carlos; Popa-Lisseanu, Ana G.; Juste, JavierRoost fidelity is an important aspect of mammalian biology. Studying the mechanisms underlying philopatry can help us understand a species’ energetic requirements, ecological constraints and social organisation. Temperate bat species notably exhibit a high degree of female philopatry considering their size, resulting in maternity colonies segregated at the mitochondrial level. We focus on the greater noctule, N...
Optimizing bat bioacoustic surveys in human‐modified Neotropical landscapes
López-Baucells, Adrià; Yoh, Natalie; Rocha, Ricardo; Bobrowiec, Paulo E. D.; Palmeirim, Jorge M.; Meyer, Christoph F. J.During the last decades, the use of bioacoustics as a non-invasive and costeffective sampling method has greatly increased worldwide. For bats, acoustic surveys have long been known to complement traditional mist-netting, however, appropriate protocol guidelines are still lacking for tropical regions. Establishing the minimum sampling effort needed to detect ecological changes in bat assemblages (e.g., activity...
Quantifying and addressing the prevalence and bias of study designs in the envi...
Christie, Alec P.; Abecasis, David; Adjeroud, Mehdi; Alonso, Juan C.; Amano, Tatsuya; Anton, Alvaro; Baldigo, Barry P.; Barrientos, RafaelBuilding trust in science and evidence-based decision-making depends heavily on the credibility of studies and their findings. Researchers employ many different study designs that vary in their risk of bias to evaluate the true effect of interventions or impacts. Here, we empirically quantify, on a large scale, the prevalence of different study designs and the magnitude of bias in their estimates. Randomised de...

Jeliazkov, Alienor; Mijatovic, Darko; Chantepie, Stéphane; Andrew, Nigel; Arlettaz, Raphaël; Barbaro, Luc; Barsoum, Nadia; Bartonova, AlenaThe use of functional information in the form of species traits plays an important role in explaining biodiversity patterns and responses to environmental changes. Although relationships between species composition, their traits, and the environment have been extensively studied on a case-by-case basis, results are variable, and it remains unclear how generalizable these relationships are across ecosystems, tax...
