Variabilidade Espacial de Atributos Químicos de Solo Sob Pastagem

Revista Vértices, 2015
The objective of this study was to analyze the spatial variability of soil chemical attributes under pasture, as well as lime and fertilizer recommendations based on the interpretation of soil chemical analysis from two sampling methods: conventional and systematic depths of 0 to 10 and 10 to 20 cm.

Testing for concordance between predicted species richness, past prioritization, and marine protected area designations in the western Indian Ocean

Conservation Biology, Volume 38, Issue 4, August 2024.
Abstract Scientific advances in environmental data coverage and machine learning algorithms have improved the ability to make large‐scale predictions where data are missing. These advances allowed us to develop a spatially resolved proxy for predicting numbers of tropical nearshore marine taxa.

Divergent selection in a Mediterranean pine on local spatial scales

Journal of Ecology, Volume 112, Issue 2, Page 278-290, February 2024.
This study highlights how divergent selection in heterogeneous microenvironments shapes and maintains the functional genetic variation within populations of long‐lived forest tree species, being the first to focus on adaptive genetic divergence between south‐ and north‐facing slopes within continuous forest stands.

The effect of place on voting behavior: The case of the Arizona proposition to legalize recreational marijuana

Politics &Policy, Volume 52, Issue 1, Page 196-226, February 2024.
Abstract In 2020, Arizonans approved Proposition 207, the Smart and Safe Arizona Act, which legalized recreational marijuana sales. Previous research has typically used non‐spatial survey data to understand marijuana legalization voting patterns. However, voting behavior can, in part, be shaped by geographic context, or place, which is unaccounted for ...
