New study reports the first record of winter breeding in Syngnathus abaster and S. typhle in a Mediterranean coastal lagoon. Findings suggest potential shifts in phenology linked to thermal anomalies: doi.org/10.1111/jfb.70195 #FishBiology #Syngnathids #ClimateChange #TransitionalWaters

New opinion piece outlines thoughts around a new path for #DNA approaches to #seafood trade #sustainability. Technically euphoria should be mitigated by commitment to #transdisciplinarity:
