Journal of Applied Toxicology, EarlyView.ABSTRACT Moringa oleifera Lam. seeds contain WSMoL, a lectin previously studied for toxicity and pharmacological effects. In this study, we investigated WSMoL (10, 25, or 50 mg/kg i.p.) for acute and 14‐day repeated‐dose toxicity, as well as genotoxicity, in Swiss mice.

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Two new species of Calea ser. Multiplinerviae (Asteraceae: Neurolaeneae) from Brazil
Nordic Journal of Botany, EarlyView.Detailed studies of specimens from Rondônia and Mato Grosso do Sul showed that two new species have been misidentified: Calea micropappa resembles Calea pilosa, but differs by leaf apex obtuse to acuminate (versus acute), paleae present (versus paleae absent), disc corolla lobes 1.2–1.3 mm long (versus 0.7–0.8 mm), and pappus scales 0.1–0.25 mm long ...

, 2018 The potential effects of the oil industry on the Sonda de Campeche (SC) marine ecosystem are of high relevance for our society due to the wealth of living and fossil fuel resources found in this sector of the Gulf of Mexico. An ecological or environmental risk analysis can be understood like an assessment procedure that allows determining the ...

Habitat loss reshuffles ecological and evolutionary interactions in a seed dispersal network
Oikos, EarlyView.In tropical forests, habitat loss reshapes species composition, favoring generalists and recently emerged lineages while specialists and older evolutionary lineages are lost. However, how changes in species ecological attributes and evolutionary history affect ecological processes is poorly explored.

Oikos, EarlyView.Phenology plays a central role in regulating energy flow and nutrient cycling, yet remains insufficiently integrated into biodiversity–ecosystem functioning frameworks. This gap is especially relevant in strongly seasonal systems, where community‐wide synchrony in leaf litterfall may arise from either temporal niche differentiation among species or ...

Urbanization and food transition in the Brazilian Amazon: From wild to domesticated meat
People and Nature, EarlyView.Abstract Urbanization is expected to influence food transitions, resulting in a shift from wild foods to more domesticated foods. Concomitantly, food insecurity and urban demand for natural resources, including wildlife, are expected to increase overall, even when the per capita consumption is expected to decrease.
