Recent studies have observed significant declines in insect abundance and populations, and ALAN has been recognized as a contributing factor. We investigated changes in nightlight intensity at various spatial scales surrounding insect traps located in Orbroicher Bruch Nature Reserve, Germany. Using a time series of global nighttime light imagery (1992\u20132010), we evaluated pixel-level trends through linear regressions and the Mann\u2013Kendall test. Paired with urban land cover delineation, we compared nightlight trends across rural and urban areas. We utilized high-resolution satellite imagery to identify landscape features potentially related to pixel-level trends within areas containing notable change. Approximately 96% of the pixel-level trends had a positive slope, and 22% of pixels experienced statistically significant increases in nightlight intensity. We observed that 80% of the region experienced nightlight intensity increases &gt;1%, concurrent with the observed decline in insect biomass. While it is unclear if these trends extend to other geographic regions, our results highlight the need for future studies to concurrently investigate long-term trends in ALAN and insect population decline across multiple scales, and consider the spatial and temporal overlaps between these patterns.<\/jats:p>","DOI":"10.3390\/rs14163876","type":"journal-article","created":{"date-parts":[[2022,8,10]],"date-time":"2022-08-10T09:42:56Z","timestamp":1660124576000},"page":"3876","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Nightlight Intensity Change Surrounding Nature Reserves: A Case Study in Orbroicher Bruch Nature Reserve, Germany"],"prefix":"10.3390","volume":"14","author":[{"given":"Jillian","family":"LaRoe","sequence":"first","affiliation":[{"name":"Applied Analysis Solutions, 535 McDonald Rd, Winchester, VA 22602, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1296-4301","authenticated-orcid":false,"given":"Christopher M.","family":"Holmes","sequence":"additional","affiliation":[{"name":"Applied Analysis Solutions, 535 McDonald Rd, Winchester, VA 22602, USA"}]},{"given":"Thorsten","family":"Schad","sequence":"additional","affiliation":[{"name":"Bayer AG, Alfred-Nobel-Str. 50, 40789 Monheim, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"108259","DOI":"10.1016\/j.biocon.2019.108259","article-title":"Light pollution is a driver of insect declines","volume":"241","author":"Owens","year":"2020","journal-title":"Biol.
