DARK MATTERS

Reflections on the ways that artificial light upsets patterns and behaviors in the natural world.

Galat (Stories of the Aurora,2016, etc.) spins childhood memories into semifictive reminiscences. Between recalling lying on her back in the snow at 10 to trace the Big Dipper and describing links between light pollution and several environmental issues as a grown-up naturalist, the author recalls camping trips and other excursions at various ages. These offer, at least tangentially, insights into how artificial lighting could affect nocturnal insects, sea turtle hatchlings, bats, and migratory birds, as well as the general hunting, mating, and nesting behaviors of animals. She closes, after a quick mention of scotobiology (the study of life in darkness), with a plea to turn off the lights whenever possible. Though she does not support this general appeal with specific practices or, for that matter, source notes for her information, she does offer a list of internet search terms for readers who want to explore the topic further. Despite illustrations that range from a close-up of a road-kill raccoon to pointless filler and passages that, paradoxically, are hard to read except in bright light because they’re printed over speckled fields of stars, this outing covers a topic that should be of interest to young stargazers and scotobiologists alike.

Enlightening, if not always easily legible, ruminations on the value of being in the dark.
