Topic analysis. A Worclouds of each topic based on $\widehat{\beta }$ values. The area occupied by each word is proportional to its $\widehat{\beta }$ value. Only words with $\widehat{\beta }>0.003$ are displayed. B For each topic, relative frequencies of papers studying each taxonomical group (humans were separated from mammals). Only papers with more than 50% of association to each topic ($\gamma$) and with taxonomy information were used for this graph (n in the top right corner of each topic graph). While topics like ‘Sports’ and ‘Human activity patterns’ are mainly human-related, a few papers related to them took approaches from animal studies to study humans and a few others did the opposite; e.g. analyses inspired in sport journals to investigate animal performance in terms of speed or distance covered.
