Anthropogenic factors such as artificial lighting at night (ALAN) and natural factors including temperature and moonlight can affect the dawn chorus pattern in birds. However, most studies are conducted in temperate regions. We investigated the effect of anthropogenic and natural factors on dawn chorus timing in eight species of bird across Hong Kong ...

Climate‐only models predict severe habitat contractions by 2100, especially in the Amazon, Cerrado and Caatinga, while southern and coastal Atlantic Forest areas remain refugial. Including artificial light at night increased projected stability and apparent suitability gains, especially in central and eastern South America.

Russia's Wartime Economy: Measuring Regional Inequalities From Outer Space
ABSTRACT We study Russia's February 2022 full‐scale invasion of Ukraine as a natural experiment to determine how sudden disruptions to international market access reshape sub‐national economic inequalities. Using remotely‐sensed nighttime lights as a proxy for economic activity, we estimate the economic effects of the war at the national and regional ...

Europe, We Have a Problem! Local Economic Winners and Losers of Border Closures
ABSTRACT In response to COVID‐19, Schengen countries temporarily reintroduced internal border controls, disrupting cross‐border integration. Using this policy change as a natural experiment and monthly nighttime lights data, we estimate the short‐run effects on European municipalities.

Disasters, Dictators, and Donors: The Impact of Foreign Aid on Economic Activity (Mis)Reporting
ABSTRACT This paper examines how governments manipulate economic data to secure more foreign disaster aid. By using nighttime lighting as a reliable measure of economic activity, we make two key findings: (1) foreign disaster aid is positively linked to a country's understatement of its gross domestic product, indicating a deliberate strategy to ...
