Our article on reduced bivalve species & functional diversity in coastal areas affected by eutrophication & deoxygenation is now available open access in Continental Shelf Research: shorturl.at/6lNzX. Here's a 🧵about our study & about the individuals who contributed to it.

Declining bivalve species and functional diversity along a coastal eutrophication-deoxygenation gradient in the northern Gulf of Mexico

Coastal eutrophication and hypoxia are growing challenges globally, yet their impacts can be difficult to evaluate because of limited biomonitoring th…

Fun new paper from our lab group! We highlight the multiple facilitative roles of tide pool consumers. Snails recycle nutrients, & their slime trails “trap” the algae they eat. They act like tiny farmers, growing their own food! 🌊🐌🧪🌎🦑https://esajournals.onlinelibrary.wiley.com/doi/10.1002/ecy.4439

The loss of consumers threatens the integrity of ecological systems, but the mechanisms underlying the effects on communities and ecosystems remain difficult to predict. This is, in part, due to the ...

Physical heterogeneity or complexity is well-known to affect biodiversity, but what about ecosystem functioning? Our new study shows heterogeneity drives cascades on rocky shores that boost foundation species, biodiversity, and multifunctionality. esajournals.onlinelibrary.wiley.com/doi/10.1002/...

Topographic heterogeneity triggers complementary cascades that enhance ecosystem multifunctionality

Topographic heterogeneity sets the stage for community assembly, but its effects on ecosystem functioning remain poorly understood. Here, we test the hypothesis that topographic heterogeneity underpi....

Happy to be starting a new side project with @gamfeldt.bsky.social@bschrobru.bsky.social using past studies to explore the role of beta-diversity in ecosystems. Nothing more motivating (apart from fieldwork) than a brainstorm with wonderful collaborators (and friends).

Happy to be visiting sites in Galicia, N. Spain, with PhD student Ruby George and the CIIMAR team. This is the southern (warmest) region in our collaborative study on the resilience of intertidal forests along a latitudinal gradient. @aec13.bsky.social@dansmale1.bsky.social@mdolbeth.bsky.social

Here, Swansea University PhD student Ruby George re-measures tagged seaweed individuals to assess growth. It’s after dark, but the scene is illuminated by torchlight.

Count me in, Lars. Looking forward to it as well.

Of course, it would be great to test this context-dependency further using a standardised experiment across continents. One could then more robustly explore the proposed sources, such as plant diversity.
