Efeito de distintas condições ambientes na durabilidade de lajes de betão armado reforçadas com laminados de CFRP pré-esforçados [PDF]

, 2016
No contexto da reabilitação de estruturas de betão armado (BA) com materiais FRP (Fiber Reinforced Polimers), a técnica EBR (Externally Bonded Reinforcement) é habitualmente utilizada para aumentar a resistência à flexão.

Variation in responses to temperature in admixed Populus genotypes predicts geographic shifts in regions where hybrids are favored

New Phytologist, Volume 249, Issue 3, Page 1509-1526, February 2026.
Summary Plastic responses of plants to their environment vary as a result of genetic differentiation within and among species. To accurately predict rangewide responses to climate change, it is necessary to characterize genotype‐specific reaction norms across the continuum of historic and future climate conditions comprising a species' range. The North

Inverse effects of soil moisture and litter quality on litter decomposition along a gradient from hyper‐arid to temperate climate

Journal of Ecology, Volume 114, Issue 1, January 2026.
We hypothesized that litter decomposition (H1) and litter quality (H2) increase with increasing soil humidity, therefore litter from the wetter sites to have the highest litter quality and decompose fastest in each site, and fastest on the wet end of the gradient (H3).

Recovering European River Invertebrate Communities Homogenize or Differentiate Depending on Anthropogenic Stress

Global Change Biology, Volume 32, Issue 1, January 2026.
(a) European river invertebrate communities showed an average increase in local richness over time (1994–2023), indicating partial local recovery following the alleviation of anthropogenic stress (e.g., point‐source pollution). However, this local recovery was not accompanied by increases in β‐diversity, likely due to persistent, unaddressed stressors,

Plant functional traits shape the provision of ecosystem services to Indigenous communities in western Amazonia

People and Nature, Volume 7, Issue 12, Page 3313-3329, December 2025.
Abstract Context. Exploring how Indigenous People interact with plants through their functional traits allows us to understand the ecological bases of plant selection. Functional traits can help explain why certain plants are consistently chosen for specific purposes across diverse cultural contexts.
