The researchers analyzed pollen samples from plants growing in areas close to arable fields and from beehives on five farms in the U.K.. (sciencedaily.com)
Collecting pollen samples in this way enabled the researchers to determine variations in the levels of eight neonicotinoids and to identify high - risk locations or months for neonicotinoid exposure for bees. (sciencedaily.com)
ITS2 successfully identified plant species present in pollen samples, but it could not produce quantitative measurements of the proportions of each. (sciencedaily.com)
