Marine Ecology podcasts

Alexandra Delbot reçoit Laurent Chauvaud et Frédéric Olivier pour explorer les coquilles de bivalves comme archives des milieux marins. La discussion explique comment les stries de croissance et leur composition chimique renseignent sur l’âge, la température, la salinité et les climats passés. Elle aborde aussi les pollutions, les perturbations acoustiques et les réponses biologiques des mollusques, envisagés comme indicateurs des changements de leur habitat.

Experiments using a giant wave machine test how salt marshes protect shorelines during extreme storms. The episode also explores evidence about Denisovan faces, orangutan mothers arranging play encounters, and the unequal effects of medieval lead exposure.

The Science Show examines mineral nodules formed around fossil shark teeth on the deep-sea floor and the ecological risks of exploiting them. The programme also considers plant responses to climate change, debates over introduced species, and the contributions and limitations of three influential scientists.

Hosted by Robyn Williams, Belinda Smith

Nature staff discuss a large survey of insect diversity in the Amazon and unusual orca behavior captured on video involving a sunfish.

Brad Gemmell discusses how changing environmental conditions affect the behaviour and ecology of small marine organisms. Topics include ctenophore predation, diatoms and ocean carbon cycling, and the role of upside-down Cassiopea jellyfish as ecosystem engineers. The conversation connects organismal physiology and movement with broader changes in marine ecosystems.

Sara Pruss discusses archaeocyath sponges, the first multicellular reef builders, and their relationship to diversification during the Cambrian. The episode traces successive reef-building groups through the geological record and asks why reefs repeatedly emerge despite environmental disruption and extinction.

Julie Simpson explores the climate role of coastal saltwater wetlands, including marshes, mangroves and seagrass meadows. Alongside habitat, water purification and coastal protection, these ecosystems remove and retain substantial amounts of carbon dioxide. The episode examines how their ecological processes connect conservation with climate mitigation.

Hosted by Madison Goldberg

Drew Harvell explores the unusual adaptations of marine invertebrates, including sponges, corals and sea stars. The discussion connects these biological capabilities with disease outbreaks, environmental change and ocean conservation, considering how resilience may help—or fail to protect—organisms under human-driven pressures.

Nina Jensen discusses ocean warming, acidification and other human pressures on marine environments. Conversation in Norwegian.
