Vanishing foundations: Florida Keys hardbottom communities lose sponges and corals
A quiet unraveling is underway in the Florida Keys. Between 2006 and 2023, the nearshore hardbottom communities that anchor this ecosystem lost their largest structure-forming sponges, like the loggerhead sponge, likely due to repeated cyanobacteria blooms. Stony corals held steady, yet sponge decline signals a decoupling of habitat from higher trophic levels. Understanding drives protection, and these empirical shifts set clear restoration priorities.
Copepod Life Cycles Shift with Marine Heatwaves: A New Ocean Indicator
Copepods are the ocean's canaries, and their response to marine heatwaves is proving more nuanced than expected. Using the Helgoland Roads time series, researchers found that blooms often contract when heatwaves strike during their peak, though most species show no consistent shift in timing beforehand. That distinction matters. It suggests selective pressure is intensifying within blooms themselves. As heatwaves grow stronger, these small disruptions could cascade through food webs, ultimately reshaping fish recruitment.
Microalgae-Larvae Carbon Transfer: A Pathway to Sustainable Aquaculture.
A 33% carbon transfer efficiency from microalgae to shrimp larvae is a measurable, validated starting point. This study on *Litopenaeus vannamei* quantifies a biological pathway that has remained poorly understood. By calculating that global hatchery seed production retains approximately 9.2 tons of carbon annually, the research gives aquaculture a calibrated, empirical tool for carbon footprint assessments. Understanding drives protection. For deeper genomic context on algal symbiosis, see our related coverage of Symbiodiniaceae Minicircles.
