Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT The American manatee (Trichechus manatus) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater.

Applied Research, Volume 5, Issue 3, June 2026.Limosilactobacillus mucosae maintained viability above 7 log CFU/g during storage of the fermented goat milk with inulin and Cereus jamacaru jam and survived over 4 log CFU/g during the in vitro gastrointestinal simulation. This jam enriched the total phenolic content of the fermented milk that achieved overall acceptability scores close to or above 7.

Redox Disruption Induced by Saquayamycin B1 Promotes Cytotoxicity in Resistant Melanoma Cells. [PDF]
ChemMedChemSaquayamycin B1 (SQ‐B1), an antibiotic isolated from Streptomyces sp. I072, triggers cell death in different melanoma cell lines, including chemoresistant SK‐MEL‐5. SQ‐B1 elevates O2•‐ and NO• on both sides of the membrane and blocks glutathione transferase (GSTP‐1) and glutathione reductase (GSR), destabilizing the GSH/GSSG antioxidant system.

Configurational Fragility of Forest Landscapes Under Multiple Anthropic Uses
Ecology and Evolution, Volume 16, Issue 6, June 2026.This study revealed that 72.2% of forest fragments and 96.1% of savannas have high configurational fragility, with a predominance of High III and Intermediate I sublevels and occasional occurrences of low fragility (Low III). Fragility is driven by pastures (57.7%), showing that landscapes with the same forest cover differ in fragility depending on the
