Concerning the verb tense in “They have called on scientific journals” (line 11), it is correct to state that:

English is widely assumed to be the “lingua franca” of research globally, but studies that
are bringing out new knowledge or insights and that are published in non-English journals and
publications are often missed due to the existing language barriers in influential academic
circles. A study by University of Cambridge researchers has found that over a third of new
conservation science documents published annually are in non-English languages, providing
examples of important science being missed at the international level. The language barrier
means that practitioners and researchers struggle to access and use new knowledge, while a
focus of research only on English may lead to biases in the understanding of key issues, the
study says. The Cambridge researchers argue that whenever science is published only in one
language, including solely in English, barriers to the transfer of knowledge are created,
according to their findings published in PLOS Biology. They have called on scientific journals to
publish basic summaries of a study's key findings in multiple languages, and for universities
and funding bodies to encourage translations as part of their “outreach” evaluation criteria.
