The increasing use of onshore wind energy is leading to an increased deployment turbines in structurally rich habitats such as forests. Forest-affiliated bats, turn, are at risk colliding with the rotor blades. Due legal protection bats Europe, it imperative restrict operation periods low bat activity avoid collisions. However, have also been observed over several hundred meters distance, indicating a displacement that cannot solely be explained by modifications habitat. This avoidance suggests indirect factors related turbine operation, e.g., wake turbulences and noise emissions. Therefore, we investigated whether forest-affiliated influenced mode (on/off) under variable conditions along transects from 80 450 m distance turbines. We divided recordings foraging guild, i.e., either narrow-space (Myotis, Plecotus), edge-space (Pipistrellus, Barbastella), or open-space (Nyctalus, Eptesicus, Vespertilio), analyzed effects speed on recorded guild mixed models. acoustic decreased 91% when were operating, while remained unaffected not operating. was neither for nor (ranging between 0 – 4 m/s 10 height above ground) found affect considered alone.

Wind energy production is growing rapidly worldwide in an effort to reduce greenhouse gas emissions. However, wind not environmentally neutral. Negative impacts on volant animals, such as bats, include fatalities at turbines and habitat loss due land-use change displacement. Siting away from ecologically sensitive areas implementing measures are critical protecting bat populations. Restricting turbine operations during periods of high activity the most effective form mitigation currently available fatalities. Compensating for offsetting mortality often practiced, because meaningful offsets lacking. Legal frameworks prevent or mitigate negative bats absent countries, especially emerging markets. Therefore, governments lending institutions key reconciling with biodiversity goals by requiring sufficient environmental standards projects.

The deployment of onshore wind power is an important means to mitigate climate change. However, turbines also produce local disamenities residents living next them, mainly due noise emissions and visual effects. Our paper analyzes how the presence affects socially optimal siting power. analysis builds on a spatial optimization model using geographical information system (GIS) data for more than 100,000 potential sites in Germany. results indicate major trade-off between goals minimizing electricity generation disamenity costs. Considering costs substantially alters – fact dominates allocation deployment. This because Germany a) correlation only moderately positive, b) exhibit larger heterogeneity These are robust variations level slope cost function that we assume modeling. findings emphasize importance supplementing support schemes with approaches address disamenties, e.g., compensation payments or differentiated setback distances settlements.

Abstract Background External tags, such as transmitters and loggers, are often used to study bat movements. However, physiological behavioural effects on bats carrying tags have rarely been investigated, recommendations the maximum acceptable tag mass rather based rules of thumb than rigorous scientific assessment. Methods We conducted a comprehensive three-step assessment potential tagging bats, using common noctules Nyctalus noctula model. First, we examined seasonal changes in body mass. Second, predicted then measured flight metabolic rate wind tunnel. Third, meta-analysis published data assess different masses weight behaviour bats. Results Individual varied seasonally by 7.0 ± 2.6 g (range: 0.5–11.5 g).

The global demand for renewable energy has led to an expansion of wind production at forested sites. deployment and operation turbines requires the clearing forest areas, resulting in significant habitat changes. To assess consequences these changes forest-associated bats, we measured acoustic activity three foraging guilds turbine clearings, adjacent edges, above nearby closed forests. Open-space edge-space bats were more active clearings edges than Similarly, narrow-space tended be are known high risk colliding with their increased gaps around may increase casualties guilds. Operation forests therefore require longer shutdown periods prevent legally protected from turbines. Although this impair yield forests, such preventive conservation measures will ultimately contribute a sustainable transition fossil sources which factors biodiversity conservation.

Abstract Urbanization has significant impacts on wildlife and ecosystems acts as an environmental filter excluding certain species from local ecological communities. Specifically, it may be challenging for some animals to find enough food in urban environments achieve a positive energy balance. Because favor small‐sized bats with low requirements, we hypothesized that common noctules ( Nyctalus noctula ) acquire at slower rate rely less conspecifics prey than rural due abundance predictable distribution of insects environments. To address this, estimated sizes measured capture rates, foraging efforts, the presence during hunting 22 noctule equipped sensor loggers environment. Even though hunted similar‐sized both environments, captured lower (mean: 2.4 vs. 6.3 attacks/min), total amount 179 377 attacks/foraging bout) Consequently, expended was higher In line our prediction, relied group hunting, likely because unnecessary environment where spatial is predictable, example, parks or around floodlights.
