Effects Of Maternal Hypoxia On Developmental Plasticity, Matilda Powell

The Plymouth Student Scientist

Developmental plasticity enables organisms to adjust phenotypes to environmental cues, yet the transgenerational consequences of maternal effects remain unclear. Hypoxia, intensified by climate change and eutrophication, triggers taxon-specific plastic responses. Daphnia magna exhibits plasticity dependence, making it a critical model species for studying environmental responses. While maternal hypoxia (MH) influences generational plasticity, its long-term impacts on reproductive and physiological traits across generations remain insufficiently explored, limiting predictions of species resilience to environmental change. This study employed a controlled two-generation design: gravid F0 adults were exposed to moderate hypoxia (40% air saturation) or normoxia (100% AS) for 8 days, with reproductive …
