  Title Timing of Avian Breeding in an Urbanised World Type Journal Article
  Year 2018 Publication Ardea Abbreviated Journal Ardea  
  Volume 106 Issue 1 Pages 31-38  
  Keywords Animals  
  Abstract (up) A large part of the world is urbanised, and the process of urbanisation is ongoing. This causes dramatic alterations of species' habitat such as increased night light, sound levels and temperature, along with direct disturbance by human activity. We used eight years of citizen science data from ten common bird species breeding in nest boxes throughout The Netherlands to study the relationship between urbanisation and a key life history trait, timing of breeding. We used nightly light levels in the form of sky brightness and light emission as a proxy for urbanisation as the dramatic change of the night-time environment is a prominent effect of urbanisation. We expected birds to lay earlier in areas with more light at night, i.e. in more urbanised areas. We found, however, no relationship between light levels and seasonal timing in the ten species studied. A limitation of our study is that there was only limited data for the areas that were urbanised most (e.g. inside cities). Most nest box study areas are located in areas with a limited level of urbanisation, and hence with relatively low light levels of light at night. The lack of data on breeding birds in more urbanised environments, which is a rapidly expanding habitat for an increasing number of species worldwide, should be the focus of attention and citizen science would be highly suitable to also provide data for such areas.

  Title Contribution à la connaissance des communautés d'Hétérocères et de Coléoptères crépusculaires et nocturnes de l’île de Porquerolles (archipel des îles d'Hyères, département du Var) en lien avec les milieux Type Journal Article
  Year 2019 Publication Scientific reports of the Port-Cros national park Abbreviated Journal  
  Volume 33 Issue Pages 127-162  
  Keywords Ecology  
  Abstract (up) À l’initiative de la municipalité d’Hyères-les-Palmiers et du Parc national de Port-Cros, une étude sur la qualité de la nuit à Porquerolles a été lancée par l’Association Nationale pour la Protection du Ciel et de l’Environnement Nocturnes (ANPCEN) en 2016. L’objectif de cette étude est de tendre vers un éclairage efcace tout en limitant son impact sur l’environnement. La présente étude entre dans le cadre de ce projet. Son objectif est d’améliorer les connaissances sur les Hétérocères et les Coléoptères crépusculaires et nocturnes de Porquerolles et d’analyser les résultats par rapport à la problématique de la pollution lumineuse. Trois points de relevé (jardin Emmanuel Lopez, bassins de lagunage, fort de la Repentance), représentatifs de différents milieux et de différentes expositions à la pollution lumineuse ont été étudiés lors de 4 sessions en 2016/2017. La qualité de la nuit selon l’étude de l’ANPCEN est moins bonne au jardin Emmanuel Lopez par rapport au bassin de lagunage et au fort de la Repentance, ce dernier étant le point ayant la meilleure qualité de nuit. Au total, 93 espèces de Coléoptères et 64 espèces d’Hétérocères ont été observées sur l’île de Porquerolles. Pour les Hétérocères, un gradient de richesse spécique est observé du point le plus exposé à la pollution lumineuse à celui qui est le moins exposé, avec 21 espèces pour le jardin Emmanuel Lopez (point n°1), 35 pour le bassin de lagunage (point n°2) et 57 pour le fort de la Repentance (point n°3). Pour les Coléoptères en revanche, le point n°1 est aussi riche que le n° 3 avec 56 espèces pour chacun alors que le point n°2 ne comporte que 38 espèces. Une fois les pistes d’actions proposées par l’ANPCEN pour la réduction des pollutions mises en place sur l’île de Porquerolles, il sera intéressant de réaliser — 128 —une nouvelle campagne d’inventaires selon le même protocole an d’identier une éventuelle évolution de la diversité et de l’abondance en Hétérocères et en Coléoptères.

  Title Observing Community Resilience from Space: Using Nighttime Lights to Model Economic Disturbance and Recovery Pattern in Natural Disaster Type Journal Article
  Year 2020 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society  
  Volume in press Issue Pages  
  Keywords Remote Sensing  
  Abstract (up) A major challenge for measuring community resilience is the lack of empirical observation in disasters. As an effective tool for observing human activities on the earth surface, night-time light (NTL) remote sensing images can fill the gap of empirical data for measuring community resilience in natural disasters. This study introduces a quantitative framework to model the recovery pattern of economic activity in a natural disaster using the Defense Meteorological Satellite Program-Operational Linescan System (DMSP-OLS) images. The utility of the framework is demonstrated in a case study of Hurricane Katrina, which uncovered the great economic impact of Katrina and spatial variation of the disturbance and recovery pattern of economic activity. Environmental and socio-economic factors that potentially influence the economic recovery were explored in statistical analyses. Instead of a static and holistic index, the framework measures resilience as a dynamic process. The analysis results provide actionable information for prompting resilience in diverse communities and in different phases of a disaster. In addition to Hurricane Katrina, the resilience modeling framework is applicable for other disaster types. The introduced approaches and findings increase our understanding about the complexity of community resilience and provide support for developing resilient and sustainable communities.

  Title Model for Artificial Night-Sky Illumination. Type Journal Article
  Year 1986 Publication Publ Astron Soc Pac Abbreviated Journal  
  Volume 98 Issue 601 Pages 364-375  
  Keywords Skyglow  
  Abstract (up) A model has been constructed to allow calculation of the night-sky brightness caused by a city at its center and outside the city, and at arbitrary zenith distances. A circular city of uniform brightness is assumed, with the total brightness proportional to the population. Molecular scattering and aerosol scattering are included, with the amount of aerosols being an adjustable parameter, and different scale heights being adopted for molecules and aerosols. The reflectivity of the ground and the fraction of light radiated above the horizontal are taken as parameters. Applications are given to several cities, to the general population-distance relations, to brightness-distance relations, and to the city center brightness-population relations

  Title Night-sky brightness at observatories and sites. Type Journal Article
  Year 1989 Publication Publ Astron Soc Pac Abbreviated Journal  
  Volume 101 Issue Pages 306-329  
  Keywords Skyglow  
  Abstract (up) A model previously constructed for night-sky brightness calculations has been modified to allow for the curvature of the earth. The model has been applied to calculate the brightness at the following observatories: Mount Wilson, Lick, Mount Palomar, Kitt Peak, Sacramento Peak, Mauna Kea, McDonald, San Pedro Martir, Mount Hopkins, Mount Lemmon, Lowell (Mars Hill), Lowell (Anderson Mesa), Fick, Iowa, Van Vleck, David Dunlap, Anglo-Australian, Haute Provence, and Cerro Tololo. Calculations have also been carried out for the following prospective observatory sites: Junipero Serra, Mount Graham, Charleston Peak, Wheeler Peak, Miller Peak, San Benito Mountain, Lowell (Hutch Mountain), Lowell (Saddle Mountain), and South Baldy (New Mexico). The model is extended to calculate magnitudes in the B photometric band.
