Seasonal and interannual variations affect plant and animal life cycle events, such as blooming flowers and migrating birds. Phenology, the study of such events, can play a role in how and when humans interact with nature, a phenomenon with potential importance to conservation.
Using three years of log data from the online encyclopedia, Wikipedia, authors of this study analyzed pageviews of articles of more than 31,000 GBIF taxonomy-matched species across 245 languages to explore seasonal patterns in Wikipedia activity. They found seasonal variation in more than 20 per cent of species pages, compared to just 6.5 per cent in a random sample of non-species pages. Most pages showed a single annuak peak, while ~10 per cent had two annual peaks.
Reflecting actual phenological patterns, pageviews for groups like insects and flowering plants exhibited higher seasonality than mammals. Seasonal patterns were not consistent across Wikipedia languages, as less than two per cent of species showed the same pattern in all languages, with greater seasonality shown for languages spoken at higher latitudes, i.e. farther from the equator.
