Climatic region
We classified each study as tropical or non-tropical according to its
latitude (tropical <
23°26’13.4”,
non-tropical > 23°26’13.4”). We used the coordinates of
each sampled city (a study could have multiple cities) to assess the
geographical and climatic distribution of the studies. When the data
were sampled in different cities (e.g., Baldock et al. 2015;
Harrison et al. 2018), we took only the centroid of the
respective region for simplicity and to avoid overplotting (Maruyamaet al. 2021).
