Ecology
1 reportEcology is investigated through experiments and observations spanning molecules, cells, organisms, populations, or ecosystems. Evidence comes from ecosystem models, food webs, and primary observations, and competing models remain viable when observations are sparse or indirect.
Comparative measurements, model results, and field surveys provide separate checks. Together they examine what spatial scale changes conclusions and how population change is measured, showing how sparse measurements or incomplete records limit certainty.

Satellite Images Reveal Penguin Diet Shifts on Antarctica's Danger Islands
NASA's Landsat 8 satellite and drone surveys have enabled researchers to monitor Adélie penguin colonies on the Danger Islands by analyzing the color of their guano, offering new insight into how changing sea ice may affect Antarctic food webs
