The document discusses NEON's goal of understanding climate change impacts through continental-scale ecological research. It describes NEON's terrestrial and aquatic observing systems that systematically sample organisms, climate, soils, and more across sites. This includes collecting insects like ground beetles and mosquitoes to measure biodiversity, abundance, and phenology. Samples are stored in NEON's natural history collections for external research use, with DNA barcoding used to validate identifications.
