Pyrethroid insecticides implicated in mass mortality of monarch butterflies at an overwintering site in California Pyrethroid insecticides implicated in mass mortality of monarch butterflies at an overwintering site in California
Since the 1980s, monarch butterfly (Danaus plexippus plexippus) populations across North America have declined by 80–95%. Although several studies have implicated pesticides as a contributing factor to their population declines, our understanding of monarch exposure levels in nature remains limited. In January 2024, a mass mortality event near an overwintering site in Pacific Grove...
Isotopic niche plasticity of American alligators within the southern Everglades Isotopic niche plasticity of American alligators within the southern Everglades
Hydrologic alterations within the Everglades have degraded American alligator (Alligator mississippiensis) habitat, reduced prey base, and increased physiological stress. Alligator body condition declined across many management areas from 2000 through 2014, prompting us to investigate the relationship between their intraspecific isotopic niche dynamics and body condition. Alligators...
Network of networks: Time series clustering of AmeriFlux sites Network of networks: Time series clustering of AmeriFlux sites
Environmental observation networks, such as AmeriFlux, are foundational for monitoring ecosystem response to climate change, management practices, and natural disturbances; however, their effectiveness depends on their representativeness for the regions or continents. We proposed an empirical, time series approach to quantify the similarity of ecosystem fluxes across AmeriFlux sites. We...
