Oregon State University science paper generated global response, financial support

A paper published last December by an Oregon State University scientist became one of the mostly widely shared science papers since 2011, according to the science communications company Altmetric, and has inspired private contributions to support further research. An international team led by William Ripple, distinguished professor in the College of Forestry at Oregon State, published “World Scientists’ Warning to Humanity: A Second Notice” in the journal BioScience.

Global warming drives global warning

In the Game of Extinction, It’s Good to Be Average

William Ripple, an ecologist at Oregon State University, is no newbie in this realm of research. In 2015 he published a paper that found that of the 74 species of large herbivores left on earth, 44 are threatened with extinction.

"Knowing how animal body size correlates with the likelihood of a species being threatened provides us with a tool to assess extinction risk for the many species we know very little about," says William Ripple, professor of ecology at Oregon State University (OSU) and lead author of the study, in a statement.
