Variação espaço-temporal dos parâmetros para a modelagem estocástica da precipitação pluvial diária no Rio Grande do Sul Temporal and spatial variation of parameters for the random modeling of daily rainfall in the state of Rio Grande do Sul, Brazil

Engenharia Agrícola, 2009
O Rio Grande do Sul é um dos maiores produtores de grãos do Brasil, sendo a maioria das culturas conduzida em sistemas não irrigados, tornando-lhes extremamente dependentes das condições climáticas e do regime pluviométrico.

Landscape features predict broad‐scale seed rain patterns across fragments of the Brazilian Atlantic Forest

Journal of Ecology, Volume 114, Issue 5, May 2026.
Along with precipitation, forest cover emerges as a fundamental driver of alpha and beta diversity in the seed rain. This highlights the role of habitat amount at the landscape level over patch‐level features, like patch size, for seed dispersal. However, increased seed density can be related to higher dispersal rates in forest borders.

‘Missing persons’: Ancient legacies of human–environment interaction in tropical natural properties inscribed under the 1972 World Heritage Convention

Archaeometry, Volume 68, Issue S2, Page S9-S30, May 2026.
Abstract Cultural and natural values form the core of World Heritage designation. Properties displaying both values, however, comprise a fraction of inscriptions (currently c. 3%) to the World Heritage List. In 1992, when that fraction stood at c. 5%, adoption of the popular ‘cultural landscapes’ category of cultural heritage in 1992 was therefore ...

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

Biotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): II. Solute Concentrations and Flux Dynamics

Biotropica, Volume 58, Issue 2, March 2026.
Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy‐derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over

Self‐Organizing Ovarian Somatic Organoids Preserve Cellular Heterogeneity and Reveal Cellular Contributions to Ovarian Aging

Aging Cell, Volume 25, Issue 1, January 2026.
We report the development and application of a mouse ovarian somatic organoid model to elucidate a fundamental new understanding of the cell biology of the aging ovarian microenvironment. ABSTRACT Ovarian somatic cells are essential for reproductive function, but no existing ex vivo models recapitulate the cellular heterogeneity or interactions within ...
