Synthetic Peptide Inhibition of Trypsin-Like Proteases in Spodoptera frugiperda (Lepidoptera: Noctuidae): Evaluating the Influence of Gut Microbiota. [PDF]

Arch Insect Biochem Physiol
Synthetic peptides (GORE1 and GORE2) inhibit trypsin‐like proteases in Spodoptera frugiperda, impairing digestion and nutritional performance. Microbiota disruption did not markedly alter enzymatic inhibition but modulated certain developmental responses.

Phytochemical diversity and seasonality are associated with a critical transition in plant-herbivore network structure. [PDF]

Ecology
Abstract Understanding critical transitions in ecological systems is fundamental for addressing various natural phenomena, from population outbreaks to sudden ecosystem collapses. Ecological interactions are key drivers of these transitions, and theory suggests that the networks formed by these interactions can undergo their own critical transition. By

Ecological and Historical Correlates of Taxonomic, Phylogenetic, and Functional Diversity of Amphibians in South American Rainforests and Savannas. [PDF]

Ecol Evol
This study identifies the key drivers of anuran amphibian diversity (taxonomic, functional, and phylogenetic) across South America's Cerrado, Amazonia, and Atlantic Rainforest. Although taxonomic and phylogenetic diversity consistently increased with long‐term climatic stability in all regions, functional diversity was primarily influenced by current ...

Engineering Characterization of Small-Scale Bioreactors for Large-Scale hiPSC Production. [PDF]

Biotechnol J
Graphical Abstract and Lay Summary Human induced pluripotent stem cells (hiPSCs) hold significant promise for regenerative medicine, and their large‐scale production requires robust and scalable bioprocesses. In this study, we applied an engineering characterization approach to estimate the impeller power number and analyze the mixing and suspension ...

Genetic Ancestry Reveals Historical Diversity of Formation Across Three Brazilian Communities of African Descent (Quilombos) in Central Brazil [PDF]

Am J Hum Biol
ABSTRACT Introduction Characterized as relatively isolated communities, many Brazilian quilombos were formed during the period of slavery in Brazil when enslaved persons (most of African descent) ran away or were abandoned by their enslavers. Quilombos in Central Brazil, whose settlement was more recent due to the relative isolation of the region ...
