Title Where forest meets urbanization: foraging plasticity of aerial insectivorous bats in an anthropogenically altered environment Type Journal Article
Year 2010 Publication Journal of Mammalogy Abbreviated Journal J. Mammal.
Volume 91 Issue 1 Pages 144-153
Keywords animals; flying mammals; acoustic monitoring; anthropogenic influence; artificial light; bat activity; Chiroptera; habitat plasticity; moon
Abstract Given worldwide rapid human population growth resulting in degradation or loss of habitats, it is important to understand how anthropogenic factors affect species presence and activity, and consequently, how well species tolerate or adapt to anthropogenically altered environments. This study, conducted in Panama, focuses on aerial insectivorous bats, a highly mobile and ecologically important, but largely understudied group. Acoustic monitoring was used to investigate habitat use in a tropical forest-town interface and microhabitat use around streetlights differing in wavelength (type of light) and accessibility (distance to vegetation). Plasticity in microhabitat use also was examined in relation to season and moonlight. We recorded a total of 25 aerial insectivorous bat species in the study area and found a subset of 20 species in town of which 18 frequently foraged around streetlights. Bat activity (passes/min) was lowest at the forest site, highest at streetlights, and intermediate in the dark areas of town. General bat activity at streetlights was concentrated at bluish-white lights compared to yellow-white and orange lights. However, bats revealed species-specific microhabitats with regard to light type, distance to vegetation, and relative light intensity. Season and moon phase affected microhabitat use around streetlights leading to microhabitat plasticity of individual species. Thus, in the forest-town interface most, but not all, aerial insectivorous bats were present in town and regularly foraged around streetlights, suggesting a species-specific tolerance for habitat alteration. Bats foraging at streetlights used microhabitats, and some species even changed microhabitats, according to season or moon phase. This indicates species-specific requirements for microhabitats and the importance of preserving habitat heterogeneity.

Title Impact of Lighting on Flora and Fauna Type Book Chapter
Year 2016 Publication Handbook of Advanced Lighting Technology Abbreviated Journal
Volume Issue Pages 1-33
Keywords Ecology; Lighting; Artificial light at night; ALAN; Plants; Animals; review
Abstract Technology, especially artificial light at night (ALAN), often has unexpected impacts on the environment. This chapter addresses both the perception of light by various organisms and the impact of ALAN on flora and fauna. The responses to ALAN are subdivided into the effects of light intensity, color spectra, and duration and timing of illumination. The ways organisms perceive light can be as variable as the habitats they live in. ALAN often interferes with natural light information. It is rarely neutral and has significant impacts beyond human perception. For example, UV light reflection of generative plant parts or the direction of light is used by many organisms as information for foraging, finding spawning sites, or communication. Contemporary outdoor lighting often lacks sustainable planning, even though the protection of species, habitat, and human well-being could be improved by adopting simple technical measures. The increasing use of ALAN with high intensities in the blue part of the spectrum, e.g., fluorescent light and LEDs, is discussed as a critical trend. Blue light is a major circadian signal in higher vertebrates and can substantially impact the orientation of organisms such as numerous insect species. A better understanding of how various types and sources of artificial light, and how organisms perceive ALAN, will be an important step towards more sustainable lighting. Such knowledge is the basis for sustainable lighting planning and the development of solutions to protect biodiversity from the effects of outdoor lighting. Maps that describe the rapid changes in ALAN are urgently needed. In addition, measures are required to reduce the increasing use and intensity of ALAN in more remote areas as signaling thresholds in flora and fauna at night are often close to moonlight intensity and far below streetlight levels.

Title Night Blight: Mapping England’s light pollution and dark skies Type Report
Year 2016 Publication Abbreviated Journal
Volume Issue Pages
Keywords Skyglow; Remote Sensing; Artificial light at night; United Kingdom; Great Britain
Abstract We can now present the most accurate ever picture of how much light is spilling up into Britain’s night skies. Detailed interactive maps have been created for England

showing districts, counties, National Parks and Areas of Outstanding Natural Beauty (AONBs) and, at a wider scale, National Character Areas. Besides these, there are high-level maps available for Scotland and Wales, so that we can now

present the most accurate ever picture of how much light is spilling up into Britain’s night sky.

Title The effect of artificial light on wildlife use of a passage structure Type Journal Article
Year 2016 Publication Biological Conservation Abbreviated Journal Biological Conservation
Volume 199 Issue Pages 25-28
Keywords Animals; animal movement; Columbia black-tailed deer; deer; Odocoileus hemionus columbianus; deer mouse; Peromyscus maniculatus; opossum; Didelphis virginiana; artificial light at night
Abstract Barriers to animal movement can isolate populations, impacting their genetic diversity, susceptibility to disease, and access to resources. Barriers to movement may be caused by artificial light, which is known to disrupt bird, sea turtle, and bat behavior, but few studies have experimentally investigated the effects of artificial light on movement for a suite of terrestrial vertebrates. Therefore, we studied the effect of ecological light pollution on animal usage of a bridge under-road passage structure. On a weekly basis, sections of the structure were subjected to different light treatments including no light added, followed by a Reference period when lights were off in all the structure sections. Sand track data revealed use by 23 mammals, birds, reptiles and amphibians, nine of which had > 30 tracks for species-level analysis. Columbia black-tailed deer (Odocoileus hemionus columbianus) traversed under unlit bridge sections much less when neighboring sections were lit compared to when none were, suggesting avoidance due to any nearby presence of artificial light. Similarly, deer mouse (Peromyscus maniculatus) and opossum (Didelphis virginiana) track paths were less frequent in the lit sections than the ambient. Crossing was correlated with temporal or spatial factors but not light for three of the other species. These findings suggest that artificial light may be reducing habitat connectivity for some species though not providing a strong barrier for others. Such information is needed to inform mitigation of habitat fragmentation in the face of expanding urbanization.
