Hey #fish and #ocean friends! The #IMCC8 call for abstracts is open! My favorite international collection of practitioners and researchers all in once place. Though always room to do better, @scbmarine.bsky.social does *standout* work to gather disciplines, geographies, ages, job types, etc. 🌏🦑🌊🧪

The call for abstracts is open for #IMCC8! We welcome global, interdisciplinary, and student-led contributions. Help shape the future of ocean conservation. 🔗 Submit your abstract: conbio.org/mini-sites/i... ⏰ Deadline: 15 May #OceanConservation #MarineScience #SCBMarine @scbmarine.bsky.social

Producing local time-series with non-standarised methods and tools, creates biases limiting our ability to detect biodiversity changes across broader scales. Our datasets from 5 Mediterrenean regions showed that data resolution must be compromised to enable meaningful comparisons.

Just completed a productive annual meeting in Pisa hosted by @dipbiounipi.bsky.social. Main conclusion: harmonize monitoring of reefs across the Mediterranean, otherwise time series collected locally will not be comperable and able to detect basin wide changes across time and space @biodiversa.eu

Recovery of marine #TopPredators is achievable. Our global review identified 481 success stories. The commonest management measure was bycatch reduction (57%), followed by the establishment of #MPAs (15%) and #InvasiveSpecies management (6%) 👉 www.frontiersin.org/journals/mar... 🌍🌐🧪 #OceanOptimism

A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right. Moving from chronological feed to the algorithmic feed also increases engagement. This is one of the most concerning papers I’ve read in awhile.

The political effects of X's feed algorithm

Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects.
Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

New paper out examining fish food web degradation in the Anthropocene. We show the structure of aquatic food webs are changing-- even when species richness doesn’t. These signals are strongly associated with decreases in body size within fish communities. www.science.org/doi/10.1126/... 🌐🐠🐡🦈🐟

Degradation of fish food webs in the Anthropocene

The decrease in body size driven by the selective species turnover is widely altering fish food web topology and function.
