In this episode, we welcome marine biologist Dr. Heneghan for a deep-dive conversation on his recent study predicting the future dynamics of oceanic life, with a specific focus on zooplankton. This research sheds light on how shifting oceanic environments, particularly in tropical regions, could result in dominance by carnivorous and gelatinous filter-feeding zooplankton, pushing out omnivorous copepods and euphausiids.

Dr. Heneghan expertly outlines how these changes could create a more direct energy pathway from phytoplankton to fish, reshaping the energy flows within marine ecosystems. However, this shift also comes with drawbacks. With declining phytoplankton biomass and the rise of less nutritious food sources, the carrying capacity for future fish communities could decrease.

The conversation takes a worrying turn as Dr. Henegh ...
