Title Effect of nocturnal lighting on an ant’s ethological and physiological traits Type Journal Article
Year 2019 Publication MOJ Ecology & Environmental Sciences Abbreviated Journal (up)
Volume 4 Issue 5 Pages 211-218
Keywords Animals
Abstract Artificial nocturnal lighting affects the nature, an impact best studied on vertebrates that are directly depending on the presence or absence of light. Here, we examined on an ant species taken as a model the effects of artificial nocturnal lighting on eleven physiological and ethological traits. Ant workers maintained under nocturnal lighting showed a decrease or a change in their level of activity, food consumption, locomotion, orientation ability, audacity, tactile perception, social relationship, learning and memory. This was largely observed during the night but the effects persisted, at a lower extend, during the day

Title Analysis of the Status of Light Pollution and its Potential Effect on Ecosystem of the Deogyusan National Park Type Journal Article
Year 2020 Publication Korean Journal of Environment and Ecology Abbreviated Journal (up)
Volume 34 Issue 1 Pages 63-71
Keywords Conservation; Ecology; Remote Sensing
Abstract This study characterized the spatial and seasonal patterns of light pollution in the Deogyusan National Park and examined the potential effects of light pollution on ecosystems in the park using light intensities derived from VIIRS (Visible Infrared Imaging Radiometer Suite) DNB (Day and Night Band) nightlight images collected in January and August 2018. Results showed that the Muju Deogyusan resort had the greatest light intensity than other sources of light pollution in the park, and light intensity of the resort was much higher in January than in August, suggesting that artificial lights in ski slopes and facilities were the major source of light pollution in the park. An analysis of an urban-natural light pollution gradient along a neighboring urban area through the inside of the park indicated that light radiated from a light pollution source permeated for up to 1km into the adjacent area and contaminated the edge area of the park. Of the legally protected species whose distributions were reported in literature, four mammals (Martes flavigula, Mustela nivalis, Prionailurus bengalensis, Pteromys volans aluco), two birds (Falco subbuteo, Falco tinnunculus), and nine amphibians and reptiles (Onychodactylus koreanus, Hynobius leechii, Karsenia koreana, Rana dybowskii, Rana huanrenensis, Elaphe dione, Rhabdophis tigrinus, Gloydius ussuriensis, Gloydius saxatilis) inhabited light-polluted areas. Of those species inhabiting light-polluted areas, nocturnal species, such as Prionailurus bengalensis and Pteromys volans aluco, in particular, were vulnerable to light pollution. These results implied that protecting ecosystems from light pollution in national parks requires managing nighttime light in the parks and surrounding areas and making a plan to manage nighttime light pollution by taking into account ecological characteristics of wild animals in the parks.

Title Movement responses of common noctule bats to the illuminated urban landscape Type Journal Article
Year 2020 Publication Landscape Ecology Abbreviated Journal (up)
Volume 35 Issue Pages 189-201
Keywords Animals
Abstract Context

Cities are a challenging habitat for obligate nocturnal mammals because of the ubiquitous use of artificial light at night (ALAN). How nocturnal animals move in an urban landscape, particularly in response to ALAN is largely unknown.

Objectives

We studied the movement responses, foraging and commuting, of common noctules (Nyctalus noctula) to urban landscape features in general and ALAN in particular.

Methods

We equipped 20 bats with miniaturized GPS loggers in the Berlin metropolitan area and related spatial positions of bats to anthropogenic and natural landscape features and levels of ALAN.

Results

Common noctules foraged close to ALAN only next to bodies of water or well vegetated areas, probably to exploit swarms of insects lured by street lights. In contrast, they avoided illuminated roads, irrespective of vegetation cover nearby. Predictive maps identified most of the metropolitan area as non-favoured by this species because of high levels of impervious surfaces and ALAN. Dark corridors were used by common noctules for commuting and thus likely improved the permeability of the city landscape.

Conclusions

We conclude that the spatial use of common noctules, previously considered to be more tolerant to light than other bats, is largely constrained by ALAN. Our study is the first individual-based GPS tracking study to show sensitive responses of nocturnal wildlife to light pollution. Approaches to protect urban biodiversity need to include ALAN to safeguard the larger network of dark habitats for bats and other nocturnal species in cities.

Title Why conservation biology can benefit from sensory ecology Type Journal Article
Year 2020 Publication Nature Ecology & Evolution Abbreviated Journal (up)
Volume 4 Issue Pages 502-511
Keywords Conservation; Animals; Vision
Abstract Global expansion of human activities is associated with the introduction of novel stimuli, such as anthropogenic noise, artificial lights and chemical agents. Progress in documenting the ecological effects of sensory pollutants is weakened by sparse knowledge of the mechanisms underlying these effects. This severely limits our capacity to devise mitigation measures. Here, we integrate knowledge of animal sensory ecology, physiology and life history to articulate three perceptual mechanisms—masking, distracting and misleading—that clearly explain how and why anthropogenic sensory pollutants impact organisms. We then link these three mechanisms to ecological consequences and discuss their implications for conservation. We argue that this framework can reveal the presence of ‘sensory danger zones’, hotspots of conservation concern where sensory pollutants overlap in space and time with an organism’s activity, and foster development of strategic interventions to mitigate the impact of sensory pollutants. Future research that applies this framework will provide critical insight to preserve the natural sensory world.

Title Impacts of Artificial Light at Night on Biological Timings Type Journal Article
Year 2017 Publication Annual Review of Ecology, Evolution, and Systematics Abbreviated Journal (up) Annu. Rev. Ecol. Evol. Syst.
Volume 48 Issue 1 Pages 49-68
Keywords Animals; Plants; Review
Abstract The use of artificial lighting to illuminate the night has provided substantial benefits to humankind. It has also disrupted natural daily, seasonal, and lunar light cycles as experienced by a diversity of organisms, and hence it has also altered cues for the timings of many biological activities. Here we review the evidence for impacts of artificial nighttime lighting on these timings. Although the examples are scattered, concerning a wide variety of species and environments, the breadth of such impacts is compelling. Indeed, it seems reasonable to conclude that the vast majority of impacts of artificial nighttime lighting stem from effects on biological timings. This adds support to arguments that artificial nighttime lighting has a quite pervasive and marked impact on ecological systems, that the rapid expansion in the global extent of both direct illuminance and skyglow is thus of significant concern, and that a widespread implementation of mitigation measures is required.
