Sentiment Analysis Captures the Known Successes and Failures of Key Reintroduction Factors

Sentiment of scientific abstracts associated with reintroduction (A) methods, (B) ecosystems, and (C) taxonomic groups. Panels describe a linear model (black line) of sentiment from the annual sample of abstracts (open circles) for each extracted term. Panels are color coded and ranked left to right by the final model value. The linear model (dotted line) for all abstracts throughout the study is a baseline reference in all panels. Studies using adaptive management or population viability analyses, studies set in scrub, marine, and grassland ecosystems, and studies reintroducing giant panda, otters, and lynx have increasingly positive sentiment. By contrast, our models suggest that reintroduction studies dealing with habitat fragmentation and invasive species, set in islands or deserts, or reintroducing condor or tortoises seem to have persistent challenges.
