Lake ice is an important resource supporting water quality, local biodiversity, arctic transportation, and regional economies. Long-term surveys of lake ice collected in situ are the gold standard for monitoring in environmental science., Here, we present ice phenology records for 78 lakes in the Northern Hemisphere spanning up to 578 years. These surveys include 12 different countries across North America and Eurasia collected by researchers, community scientists, priests, and digital observations. This database includes information...

The causative bacterium of Lyme disease, Borrelia burgdorferi, expanded from an undetected human pathogen into the etiologic agent of the most common vector-borne disease in the United States over the last several decades. Systematic field collections of the tick vector reveal increases in the geographic range and population size of B. burgdorferi that coincided with increases in human Lyme disease incidence across New York State. Here we investigate the impact of environmental features on the...
