趨勢摘要
More papers are appearing while per‑paper citation influence has softened.
Field-weighted citation impact moved from 8.06 to 4.89. If you aim for high citedness per paper, expect a lower average than before. The share of top-10% cited papers moved from 62.7% to 45.3%. Do not assume a published paper will land among the most‑cited in its field as often as previously. Photosynthetic Processes and Mechanisms rose from 0.0% to 5.0% of what the journal runs. Consider submitting work on photosynthesis now that the journal is publishing more on that theme. Authors from US went from 49.4% down to 45.6%. Expect a slightly more international author mix than in past periods.
