Biocrusts increase the resistance to warming-induced increases in topsoil P pools. [PDF]

open access: yesJ Ecol, 2022
Our findings provide novel insights on the responses of soil P pools to warming and rainfall reduction, and highlight the importance of biocrusts as modulators of these responses in dryland ecosystems. Our results suggest that the observed negative impacts of warming on dryland biocrust communities will decrease their capacity to buffer changes in ...

Nutrient‐based species selection is a prevalent driver of community assembly and functional trait space in tropical forests

open access: yesJournal of Ecology, Volume 111, Issue 6, Page 1218-1230, June 2023., 2023
Our results demonstrate that soil nutrient‐based species selection is a prevalent driver of community assembly in tropical forests, a process mediated by key functional traits within the leaf and wood economics spectrum. Functional space size and its filling increase with soil nutrient concentration, whereas niche vacancy decreases.

Phosphorus fractions in an agricultural chronosequence under tillage regimes in the Cerrado area in Goiás, Brazil

open access: yesSemina: Ciências Agrárias, 2016
The increase in the amount and quantity of soil organic matter (SOM), as well as the use of phosphorus-based fertilizers in the superficial soil layer in areas under tillage regimes (TR), may affect phosphorus (P) dynamics in the soil.
