  Title Magnitude of urban heat islands largely explained by climate and population Type Journal Article
  Year 2019 Publication Nature Abbreviated Journal Nature  
  Volume 573 Issue (down) 7772 Pages 55-60  
  Keywords Remote Sensing  
  Abstract Urban heat islands (UHIs) exacerbate the risk of heat-related mortality associated with global climate change. The intensity of UHIs varies with population size and mean annual precipitation, but a unifying explanation for this variation is lacking, and there are no geographically targeted guidelines for heat mitigation. Here we analyse summertime differences between urban and rural surface temperatures (DeltaTs) worldwide and find a nonlinear increase in DeltaTs with precipitation that is controlled by water or energy limitations on evapotranspiration and that modulates the scaling of DeltaTs with city size. We introduce a coarse-grained model that links population, background climate, and UHI intensity, and show that urban-rural differences in evapotranspiration and convection efficiency are the main determinants of warming. The direct implication of these nonlinearities is that mitigation strategies aimed at increasing green cover and albedo are more efficient in dry regions, whereas the challenge of cooling tropical cities will require innovative solutions.

  Title LEDs for photons, physiology and food Type Journal Article
  Year 2018 Publication Nature Abbreviated Journal Nature  
  Volume 563 Issue (down) 7732 Pages 493-500  
  Keywords Review; Lighting; Human Health; Plants  
  Abstract Lighting based on light-emitting diodes (LEDs) not only is more energy efficient than traditional lighting, but also enables improved performance and control. The colour, intensity and distribution of light can now be controlled with unprecedented precision, enabling light to be used both as a signal for specific physiological responses in humans and plants, and as an efficient fuel for fresh food production. Here we show how a broad and improved understanding of the physiological responses to light will facilitate greater energy savings and provide health and productivity benefits that have not previously been associated with lighting.

  Title Modification of Mammalian Sexual Cycles; Reactions of Ferrets (Putorius vulgaris) of Both Sexes to Electric Light Added After Dark in November and December Type Journal Article
  Year 1932 Publication Proceedings of the Royal Society B: Biological Sciences Abbreviated Journal Proceedings of the Royal Society B: Biological Sciences  
  Volume 110 Issue (down) 767 Pages 322-336  
  Keywords Animals  
  Abstract Studies by Rowan (1930 and preceding papers) and Bissonnette (1931, a, b, 1932, a, b, and preceding papers) and Bissonnette and Wadlund (1931) have shown that in juncos, canaries, crows and starlings, at least, among birds, the sexual cycle is conditioned to a great degree by daily light ration. Sexual activity in both males and females can be modified at will by altering the daily light ration with controlled electric lighting from ordinary incandescent bulbs. Gonad changes, controllable in this way, are closely correlated with migrations in juncos and crows, as demonstrated by Rowan (1930, and preceding papers), who, however, maintains that it is the added periods of muscular exercise, rather than the light, as such, that condition these changes, in spite of the fact that it is always the added light he uses, rather than exercise, to get his effects. Bissonnette disagrees, and holds it is the light that is the major factor in conditioning the changes in sexual cycles. It has been found, also, that intensity and colour, or wave-length, as well as daily period of light are factors in conditioning sexual activity in starlings, and the method of increase of light also plays a part (Bissonnette, 1931, b, 1932 ; Bissonnette and Wadlund, 1931).

  Title Ecological light pollution affects anuran calling season, daily calling period, and sensitivity to light in natural Brazilian wetlands Type Journal Article
  Year 2019 Publication The Science of Nature Abbreviated Journal Sci Nat  
  Volume 106 Issue (down) 7-8 Pages 46  
  Keywords Animals  
  Abstract Ecological light pollution alters an environment's light cycle, potentially affecting photoperiod-controlled behavior. Anurans, for example, generally breed nocturnally, and the influence of light pollution on their natural history may therefore be especially strong. In this study, we tested this hypothesis by measuring male calling behavior of anuran communities in natural wetlands in southern Brazil exposed or not exposed to street lights. We recorded seasonal and diel calling activity and calling response to a light pulse. The peak calling season differed between continuously lit and unlit locations with most species in illuminated wetlands shortening their calling season and calling earlier in the year. In unlit breeding sites, Boana pulchella, Pseudis minuta, and Pseudopaludicola falcipes confined their calling activity to well-defined hours of the night, but in continuously lit areas, these species called more continuously through the night. A 2-minute light pulse inhibited calling, but only in unlit wetlands. After a light pulse, frogs quickly resumed calling-suggesting acclimatization to brief artificial light exposure. Our field experiment presents a convincing example of ecological light pollution showing that artificial light alters the seasonal and diel calling time of some South American wetland anurans. It also documents their acclimatization to brief lighting when being continuously exposed to light.
