The lunar cycle influences frogs' vocal activity. Herein we examined a community of 37 Brazilian species to elucidate how their vocal activity is influenced by such a cycle. We found that most species prefer the darkest phase for vocalizing. This result indicates that artificial lighting could interfere with the species' natural behaviors, affecting their conservancy. To find this, we observed the vocal activity of 1691 frogs for 882 d in a way to better understand Brazilian biodiversity.

Human population growth imposes increasing demands on crop yield (i.e., crop production per unit area). Worryingly, first signs of yield deceleration and stagnation were reported. In our study we show how crop cultivation region, type of harvested organ, pollinator dependency, and life form affect yield growth and/or stability of globally important crops. Our results together advocate for a more diverse agriculture involving the cultivation of different crops with different ecological features.
