What Half a Million Tweets Revealed About Invasive Species

A study analyzing over 500,000 tweets from 2006 to 2021 found that public discourse on invasive species heavily favors charismatic animals over ecologically harmful plants.

The research, led by the University of Galway and published in Ecology & Society, and involving Newcastle University, demonstrates how charismatic megafauna and dramatic narratives shape online conversations while scientifically relevant species, particularly invasive plants, generate minimal public engagement.

"We had a unique opportunity with Twitter's free academic access to understand what drives public attention to invasive species at a scale that had not been done before and where the gaps lie relative to scientific priorities,"

says Dr. Susan Canavan, Honorary Researcher with the School of Natural Sciences at the University of Galway, who led the international research team.
