Does wind disrupt overwintering monarch butterfly clusters? An observational study of western monarchs Does wind disrupt overwintering monarch butterfly clusters? An observational study of western monarchs
Wind protection is a central focus of western monarch butterfly (Danaus plexippus) overwintering habitat conservation. The Wind Disruption Hypothesis guiding management decisions predicts that winds at or above 2 m/s disrupt clusters and that cluster abundance decreases as wind speed increases. At two California groves during the 2023–2024 overwintering season, we paired time-lapse...
USGS Geochron—A database of geochronological and thermochronological dates and data—Technical documentation USGS Geochron—A database of geochronological and thermochronological dates and data—Technical documentation
Geochronological and thermochronological data are essential for constraining the timing and rates of geological processes, supporting geologic mapping, natural hazard assessment, and resource exploration. The U.S. Geological Survey (USGS) Geochron Database is a centralized, relational database that integrates USGS and State geological survey data in accordance with the National Geologic...
