How bright the moon: correcting a propagated figure error in the literature

Last year, the National Park Service released our report, Artificial night lighting and protected lands: Ecological effects and management approaches (Longcore and Rich 2016), which had been in the works for quite a while. Our colleague Andrej Mohar, while enthusiastic about the report overall, pointed out that a figure that we had included of natural … Continue reading How bright the moon: correcting a propagated figure error in the literature

Spatial and Temporal Analysis of Nighttime Lighting In and Around National Parks

Yu Chuan Shan, Ben Banet, and I have been working the past couple of years on developing a monthly database of upward radiance from within and buffers around all of the National Park units in the United States.  They are presenting the research today at the USC undergraduate research symposium.  The results presented only scratch … Continue reading Spatial and Temporal Analysis of Nighttime Lighting In and Around National Parks

Healthy Urbanism in Polluted Cities

  Colleagues at USC Environmental Health Centers are putting together a 1-day conference titled Parks, Pollution, and Obesity. I’ve been awarded a USC Architecture Graduate Research Scholar grant to work with this group to bridge between the public health researchers and landscape architects and urbanists. The premise is as follows. Awareness among landscape architects, urban … Continue reading Healthy Urbanism in Polluted Cities

Unintentional Media Blitz

As a result of the new atlas of of artificial night sky brightness I ended up doing a lot of interviews for national and international outlets, including Science Magazine, Takepart.com, Christian Science Monitor, Scientific American, and USA Today. Then the American Medical Association released a statement on LED lighting (for which I had provided some … Continue reading Unintentional Media Blitz

Predicting Continental-Scale Bird Migration Routes from Landscape Parameters

William Winters, one of my GIST students, successfully filed his MS thesis last fall, in which he created proof-of-concept models for bird migration routes at the continental scale.  We developed the topic as a way to fill in a missing scale in the efforts to reduce mortality of birds at towers and buildings.  At the … Continue reading Predicting Continental-Scale Bird Migration Routes from Landscape Parameters
