  Title (up) Ecological effects of artificial light at night on wild plants Type Journal Article
  Year 2016 Publication Journal of Ecology Abbreviated Journal J Ecol  
  Volume 104 Issue 3 Pages 611-620  
  Keywords Plants; wild plants; photobiology; Circadian; Ecophysiology; light cycles; light pollution; photoperiodism; photopollution; physiology; sky glow; urban ecology  
  Abstract 1.Plants use light as a source of both energy and information. Plant physiological responses to light, and interactions between plants and animals (such as herbivory and pollination), have evolved under a more or less stable regime of 24-hour cycles of light and darkness, and, outside of the tropics, seasonal variation in daylength.

2.The rapid spread of outdoor electric lighting across the globe over the past century has caused an unprecedented disruption to these natural light cycles. Artificial light is widespread in the environment, varying in intensity by several orders of magnitude from faint skyglow reflected from distant cities to direct illumination of urban and suburban vegetation.

3.In many cases artificial light in the nighttime environment is sufficiently bright to induce a physiological response in plants, affecting their phenology, growth form and resource allocation. The physiology, behaviour and ecology of herbivores and pollinators is also likely to be impacted by artificial light. Thus, understanding the ecological consequences of artificial light at night is critical to determine the full impact of human activity on ecosystems.

4.Synthesis. Understanding the impacts of artificial nighttime light on wild plants and natural vegetation requires linking the knowledge gained from over a century of experimental research on the impacts of light on plants in the laboratory and greenhouse with knowledge of the intensity, spatial distribution, spectral composition and timing of light in the nighttime environment. To understand fully the extent of these impacts requires conceptual models that can (i) characterise the highly heterogeneous nature of the nighttime light environment at a scale relevant to plant physiology, and (ii) scale physiological responses to predict impacts at the level of the whole plant, population, community and ecosystem.

  Title (up) Effect of Clonal Selection on Daphnia Tolerance to Dark Experimental Conditions Type Journal Article
  Year 2016 Publication PloS one Abbreviated Journal PLoS One  
  Volume 11 Issue 7 Pages e0159628  
  Keywords Darkness, Animals  
  Abstract Recent studies have demonstrated substantial effects of environmental stress that vary among clones. Exposure to ultraviolet radiation (UV) is an important abiotic stressor that is highly variable in aquatic ecosystems due to diel and seasonal variations in incident sunlight as well as to differences in the UV transparency of water among water bodies, the depth distribution of organisms, and the ability of organisms to detect and respond to UV. In contrast to the convention that all UV is damaging, evidence is accumulating for the beneficial effects of exposure to low levels of UV radiation. Whereas UV has been frequently observed as the primary light-related stressor, herein we present evidence that dark conditions may be similarly “stressful” (reduction of overall fitness), and stress responses vary among clones of the freshwater crustacean Daphnia parvula. We have identified a significant relationship between survivorship and reduced fecundity of clones maintained in dark conditions, but no correlation between tolerance of the clones to dark and UV radiation. Low tolerance to dark conditions can have negative effects not only on accumulated stresses in organisms (e.g. the repair of UV-induced damage in organisms with photolyase), but potentially on the overall physiology and fitness of organisms. Our results support recent evidence of the beneficial effects of low-level UV exposure for some organisms.

  Title (up) Effect of high wavelengths low intensity light during dark period on physical exercise performance, biochemical and haematological parameters of swimming rats Type Journal Article
  Year 2016 Publication Acta Physiologica Hungarica Abbreviated Journal Acta Physiol Hung  
  Volume 103 Issue 1 Pages 112-120  
  Keywords Animals  
  Abstract Nocturnal rodents should be assessed at an appropriate time of day, which leads to a challenge in identifying an adequate environmental light which allows animal visualisation without perturbing physiological homeostasis. Thus, we analysed the influence of high wavelength and low intensity light during dark period on physical exercise and biochemical and haematological parameters of nocturnal rats. We submitted 80 animals to an exhaustive exercise at individualised intensity under two different illuminations during dark period. Red light (> 600 nm; < 15lux) was applied constantly during dark period (EI; for experimental illumination groups) or only for handling and assessments (SI; for standard illumination groups). EI led to worse haematological and biochemical conditions, demonstrating that EI alone can influence physiological parameters and jeopardise result interpretation. SI promotes normal physiological conditions and greater aerobic tolerance than EI, showing the importance of a correct illumination pattern for all researchers that employ nocturnal rats for health/disease or sports performance experiments.

  Title (up) Effect of Supplemental Light on the Quality of Green Asparagus Spears in Winter &lsquo;Fusekomi&rsquo; Forcing Culture Type Journal Article
  Year 2016 Publication Environment Control in Biology Abbreviated Journal Environmental Control in Biology  
  Volume 54 Issue 3 Pages 147-152  
  Keywords Plants  
  Abstract Winter ‘fusekomi’ forcing culture of asparagus is becoming popular in Japan because the method can make production of asparagus possible during cold season. However, there are some problems such as color of the spear is pale, and rutin content is lower compared to spring harvest due to the low light intensity, especially in the production area which has much snow and short sunshine. The objective of this study was to clarify the effect of supplemental lighting on the yield, rutin content, sugar component (fructose, glucose, sucrose), and the color of spears. The experiments were conducted by using different irradiation time and different numbers of fluorescent lamps hanging on the tunnel poles over the cultivation bed on the winter ‘fusekomi’ forcing culture. Compared to the control, rutin content was significantly increased under supplemental lighting plots. No significant difference or negative impact was observed in sugar contents and yield on each plot. Moreover, spear color also appeared to be better under supplemental lighting than that of the control. These results suggested that supplemental lighting was effective to improve the quality of asparagus spears (such as rutin contents, spears color), especially for the production area that has low light intensity or in short day conditions.
