Biochemical Responses of Anopheles spp. Larvae to a Novel Brazilian BR101 Bacillus thuringiensis var. israelensis Formulation: Oxidative Stress, Detoxification Enzymes, and Safety for Nontarget Notonectidae and Gerridae Aquatic Insects

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Bti BR101 exhibits strong larvicidal activity against Anopheles larvae spp., with dose‐dependent mortality and LC50 of 3.13 µg/mL. Bti increases ROS, lipid and protein oxidation, and activates antioxidant enzymes (SOD, CAT, GPx) and detoxification pathways (MFO and esterases), indicating moderate oxidative stress.

Forest structure and connectivity drive the functional recovery of seed rain

Journal of Ecology, Volume 114, Issue 2, February 2026.
Local forest structure and landscape‐scale connectivity shape distinct but complementary pathways of the functional recovery of seed rain in tropical forests. Structural complexity promotes functionally diverse plant–frugivore interactions locally, while connectivity facilitates the arrival of late‐successional seeds from external sources.
