Ten simple rules to follow when cleaning occurrence data in palaeobiology

Palaeontology, Volume 68, Issue 5, September/October 2025.
Abstract Large datasets of fossil occurrences, often downloaded from online community‐maintained databases, are a vital resource for understanding broad‐scale evolutionary patterns, such as how biodiversity has changed through time and space. Such datasets, however, are not infallible and must be ‘cleaned’ of inaccurate, incomplete, or duplicate data ...

The Occurrence Variability of Severe Scintillation and Range Spread F From the Varying Nature of Large‐to‐Meso‐Scale‐Wave‐Structures: Observations and Simulation

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract The occurrence variability on a day‐to‐day basis of severe S4 scintillation and range‐spread F (RSF) which are the manifestations of the most robust dynamical spread F phenomenon in the nighttime equatorial‐low‐latitude ionosphere, remains intriguing to date. The complex nature of large‐to‐meso‐scale‐wave‐structure (LSWS) that results from the

Espectroscopia anelástica em ligas de Nb-16% p. Ti

Materials Research, 2003
Átomos de oxigênio, presentes em metais com estrutura cristalina cúbica de corpo centrado, são localizados preferencialmente em sítios octaedrais. Na ausência de uma tensão mecânica externa, estes átomos são distribuídos aleatoriamente.

Spatial predictors of landowners' engagement in the restoration of the Brazilian Atlantic Forest

People and Nature, Volume 7, Issue 1, Page 247-264, January 2025.
Abstract Forest restoration can potentially contribute to multiple global sustainable development goals. Yet, little is known about the factors associated with local actors' choice to engage in restoration, limiting the development of effective scaling strategies.

Plant antagonistic facilitation across environmental gradients: a soil‐resource ecosystem engineering model

New Phytologist, Volume 244, Issue 2, Page 670-682, October 2024.
Summary Theory questions the persistence of nonreciprocal interactions in which one plant has a positive net effect on a neighbor that, in return, has a negative net impact on its benefactor – a phenomenon known as antagonistic facilitation. We develop a spatially explicit consumer‐resource model for belowground plant competition between ecosystem ...

Nonphotochemical quenching kinetics GWAS in sorghum identifies genes that may play conserved roles in maize and Arabidopsis thaliana photoprotection

The Plant Journal, Volume 119, Issue 6, Page 3000-3014, September 2024.
SUMMARY Photosynthetic organisms must cope with rapid fluctuations in light intensity. Nonphotochemical quenching (NPQ) enables the dissipation of excess light energy as heat under high light conditions, whereas its relaxation under low light maximizes photosynthetic productivity.
