Trait coordination reveals the fast–slow plant economics spectrum along the vertical canopy profile in central Amazonian forests

Functional Ecology, Volume 39, Issue 12, Page 3596-3610, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding how environmental drivers affect tree functioning is essential to improve predictions of tropical forests' response to climate change. While functional traits directly influence tree performance, our understanding of how canopy environments shape their ...

Improving the Performance of 3-D Radiative Transfer Model FLIGHT to Simulate Optical Properties of a Tree-Grass Ecosystem

Remote Sensing, 2018
The 3-D Radiative Transfer Model (RTM) FLIGHT can represent scattering in open forest or savannas featuring underlying bare soils. However, FLIGHT might not be suitable for multilayered tree-grass ecosystems (TGE), where a grass understory can dominate ...

Finding floral and faunal species richness optima among active fire regimes

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

Prenatal evaluation, diagnosis and management of fetal corpus callosal abnormalities: international Delphi consensus

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 5, Page 582-588, November 2025.
ABSTRACT Objective The corpus callosum (CC) is an interhemispheric structure that facilitates communication between the two cerebral hemispheres. Anomalies of the CC are frequent and associated with a wide spectrum of altered neurodevelopmental outcomes.

Foliar spectral signatures reveal adaptive divergence in live oaks (Quercus section Virentes) across species and environmental niches

New Phytologist, Volume 248, Issue 1, Page 370-388, October 2025.
Summary Genomic tools have advanced our understanding of species and population structure, but distinguishing neutral from adaptive evolution remains challenging due to limited methods for measuring a broad spectrum of phenotypic traits. We used spectroscopic data from preserved leaves to test for adaptive divergence among populations of live oaks ...

RELAÇÕES JURIDICAS E DIREITOS FUNDAMENTAIS AFETOS AO ESPECTRO RADIOELÉTRICO

Revista de Estudos Jurídicos da UNESP, 2012
O espectro radioelétrico, talvez por sua natureza peculiar, é um dos bens públicos menos abordados e discutidos pela doutrina pátria. A falta de uma doutrina consistente e sistematizada sobre o tema resulta num vazio jurídico que pode afetar a busca dos ...
