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.

Research on the effect of close-to-nature management (CTNM) on the univariate and bivariate distribution of the spatial structure of forest stands provides a scientific basis for the evaluation of CTNM implemented in forestry and further promotes the success of forest management.

Cerrado savannas in Brazil are under increasing pressure. Long-term vegetation dynamics (1987–2019) of a Cerrado area showed marked woody plant encroachment (WPE) processes, possibly linked to fire and grazing suppression. Open shrubby grasslands and wetlands shrunk, while forest and denser woodlands increased, concurrently with vegetation indexes (NDVI). Decreasing open cerrado and wetlands may imply biodiversity and water supply losses. WPE should be considered for Cerrado conservation.

Biocrusts are associations among drought-tolerant organisms and are crucial for maintaining the steady state of ecosystems subjected to high environmental stresses. The elaboration of sustainable plans for their preservation, restoration, and spreading is a recent strategy to combat land degradation and desertification. This review highlights the most relevant achievements and the critical points still open for the biotechnological application of cyanobacteria and mosses to soil restoration.
