Summary: This study provides new insights into the structural architecture and tectonic development of the Brazilian Equatorial Margin during the opening of the Equatorial Atlantic Ocean. It reveals the role of Precambrian heritage in the crustal compartmentalization and improves previous evolution models of the margin.

Summary: This study compared the performance of a LIDAR and a SODAR in evaluating wind speed at different altitudes, finding that the LIDAR had slightly better performance in horizontal velocity and sampling efficiency compared to the SODAR, with both sensors showing similar performance at different locations.

Summary: This study investigates the offshore Cear??a Basin and its basement in the central part of the Brazilian Equatorial Margin to understand the influence of Precambrian crustal domains on basin evolution, determine the deformation style of reactivated basement faults, and assess their interaction with the oceanic Romanche Fracture Zone.

Summary: This study examines the variability in intrapopulation plasticity and whether stressful conditions shape plasticity to an optimal level in a classical insect study system. The results suggest the existence of heritable, ecologically relevant plasticity differences among individuals, which is crucial for predicting the sensitivity of biological systems to environmental changes.

Summary: Stratigraphy along the Brazilian Equatorial Margin is important for understanding the geodynamic history of the South Atlantic Ocean. This study focuses on three sedimentary basins-Barreirinhas, Ceara, and Potiguar-to quantify their stratigraphic and subsidence histories. The results show that Barreirinhas and Ceara Basins can be considered as failed rifts, while the Potiguar Basin experienced significant stretching and formation due to Cretaceous rifting.

Summary: This study reconstructs the changes in deep-water oceanographic currents in the Equatorial Atlantic Ocean during the Cenozoic by analyzing the evolution of contourite depositional systems and mixed contourite-turbidite systems. The results indicate the establishment and direction inversion of proto-NBC, and the alternation of CDS and mCTS in response to sea level and oceanographic regimes. A six-phase evolutionary model is proposed summarizing the changes in the Brazilian Equatorial Margin. This study contributes to the understanding of the Atlantic Meridional Over-turning Circulation and provides a baseline for future investigations.

Summary: Research has shown that genetic improvement of Brazilian barley cultivars has increased the proportion of flowering period development, altering the length of some growth stages but not changing the duration between emergence and double ridges. Modern barley cultivars have a leaf architecture that allows for better penetration of photosynthetically active radiation, favoring photosynthesis.

Summary: In this study, Curie Point Depth (CPD) was calculated for the Brazilian Equatorial Margin using Fourier and continuous wavelet transforms, with a focus on random and fractal magnetization models. Results showed variations in heat flow and Curie isotherm depths between the continental and deep-water oceanic domains, indicating differences in geothermal characteristics and lithospheric mantle magnetization.

Summary: This study aimed to investigate the ecophysiological responses of accessions from different environmental origins under drought and salinity conditions in tall wheatgrass. The results showed that accessions with superior stress tolerance can be identified using the combination of delta C-13 value, Na+/K+ ratio, and canopy structural variables. The stress tolerance of tall wheatgrass can be utilized to expand forage production.

Summary: Global rice crop production is threatened by increasing temperatures and drought, which negatively affect rice's characteristics and productivity. Physiological changes, such as stomata closure and reduced photosynthesis, occur under heat and drought stress, leading to decreased crop yield. These stresses also cause metabolic changes, including increased enzyme activities and reactive stress metabolites. The reproductive stage of rice is particularly sensitive to high temperature and drought, resulting in low seed setting and grain yield. Genetic improvement and development of stress-tolerant rice varieties are the best approaches to enhance yield even under stress conditions. This article summarizes the effects of heat and drought stresses on rice's physiological traits and explores different approaches for managing these stresses.

Summary: Passive sampling device (PSD) with developmental toxicity assays in zebrafish can effectively detect the whole mixture toxicity of bioavailable non-polar organics in environmental sites. By incorporating RNA-Seq, this study investigated the toxicity of PSD extracts from two locations in Portland Harbor Superfund Site on zebrafish embryos. The results showed that RM 6.5W had higher concentrations of PAHs and exhibited higher toxicity, while the gene expression profiles were similar between the two extracts.

Summary: Global warming generally advances the spring phenology of extratropical trees, but in some cases, the advancing has leveled off, indicating a declining temperature sensitivity. The potential reasons for this decline have been debated, but no direct experimental evidence has been found. Through scenario simulations, this study examines the ecophysiological traits that restrict the advancing of spring phenology in four subtropical tree species under global warming. The results show that seemingly small and often neglected details of ecophysiological responses to temperature change significantly affect the spring phenology of trees under climatic warming.

Summary: This study verifies that POD1 is a good indicator for explaining the development of O-3 VFI and helps differentiate co-occurring drought and O-3 VFI in oak forests. The response of oak species to O-3 and drought varied, with Quercus ilex exhibiting no symptoms under O-3 treatment and Quercus robur being more susceptible to drought. The results also indicate that O-3 and drought have negative effects on plant biomass and physiological parameters.
