Marine Biology 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.

The hosts discuss nitrogen fixation in a marine alga and the evidence for a nitrogen-fixing organelle. Related topics include plastic pollution, antimicrobial resistance and the rumen microbiome. The episode links microbial evolution and physiology with marine nutrient cycling.

Hosted by Vincent Racaniello, Michael Schmidt

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.

Katie Lotterhos discusses a survey of the effects of US policy changes on ecology, evolution, marine and environmental research. The conversation then turns to oysters as a system for studying local adaptation and the genomic vulnerability of populations facing environmental change.

Hosted by Marty Martin, Cameron Ghalambor

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.

Simen Sætre and Kjetil Østli discuss salmon farming and the environmental and animal-health questions surrounding the industry. Conversation in Norwegian.
