In situ studies are difficult, but worth the effort! We simulated realistic Artificial Light At Night #ALAN by installing new lights in a dark zone and saw that it did not directly impact seagrass, but caused long term physiological changes. #fieldwork at night was fun! doi.org/10.1016/j.ma...
Finally: What happens when weather anomalies push down ⏬🌊the sea-level over days or weeks? We describe Dry Tides as a new category of climatic disturbance, often associated to #heatwaves or high pressure, that leaves intertidal organisms with dry feet💀 onlinelibrary.wiley.com/doi/10.1111/...
Perfect timing with the current #Heatwave 🌡️ in Europe: I've got a BIG article about another kind of #ExtremeWeather to share very soon (I am super excited because I went out of my comfort zone with this one). Hint:🌊⏬✅⏫🚫= 💀 Stay tuned! #ClimateChange #ExtremeClimate
Glorious spring tide and weather ☀️ 🌊 5️⃣ days, 3️⃣ sites, 5️⃣ treatments & 8️⃣7️⃣RAS later 😮💨 all pools & plots from Robin’s article were re-surveyed 4️⃣ years on 🙌 www.sciencedirect.com/science/arti... lots of lovely fresh 📈 @robingauff.bsky.social @bastien-taormina.bsky.social @ifremer.bsky.social
I love research that nuances established ideas in socio-scoentifc contexts. A new one by @karencastro.bsky.social and @evanschwindt.bsky.social shows how shipwrecks can have both, positive and negative effects, challenging their wide deployment for recreation doi.org/10.25260/EA.25.35.1.0.2388

Embracing that eco-engineering helps little for ecol. restoration, but still increases biodiversity, lets us think differently and actually design beautiful marine urban green spaces with humans in mind. We could make these areas attractive for recreational activities and increase human wellbeing.
our new paper shows that artif. tidepools increased biodiversity, but their community was distinct from natural habitats and prone to introduced species presence. We make the point that eco-eng. has no true value for restoration but they could be considered as marine green spaces akin to parks (3/3)
Mixed messages: Eco-engineered tide pools can provide both positive and negative contributions, with the possibility of increasing introduced species diversity
With marine urbanisation on the rise, decision makers and managers are aiming to mitigate and offset impacts arising from the destruction of natural h…

Did a night dive 🌌🤿 on Mediterranean sea grass yesterday evening and noticed that we were surrounded by … frogs!? Found out that scorpionfish sing at night, which is my favorite fish info of the moment 💙 Sound recording: www.facebook.com/share/v/14JG... Article doi: doi.org/10.1242/jeb....
While I think that #ecoengineering has some value to provide ecosystem services to humans, I am critical concerning its use for rehabilitation/impact compensation. For example it may increase the risk associated to introduced species. doi.org/10.1016/j.ma...

Awesome presentation by Giada Riva on the absence of biotic homogenization at regional scale at the #ITRS #ITRS2025 This was one of the unexpected outcomes of the HERMES campaign and shows that we still have a lot to learn about marine urban #ecosystems
My talk on the #ITRS #ITRS2025 will be on friday 4th at 15:45. If you're not available at this time don't hesitate to talk to me during todays Icebreaker!
Robin P.M. Gauff@robingauff.bsky.social · last yr.The HERMES campaign will feature in two presentations at the International Temperate Reefs Symposium #conference I will present how some urban artificial habitats may have insular properties. The implications of this insight on understanding urban community assembly are huge! #ITRS #ITRS2025
My favorite substrate so far was this abandoned fin with over 20 different Bryozoa species 🌈

For the HERMES 2023 #fieldwork we spent hundreds of hours under water to measure ecosystem functions like photosynthesis, but also months in the laboratory to generate our #taxonomic dataset of 500 (!) species. This helped investigate biotic homogenization and island biogeography in urban habitats.
In 2023 we conducted the Homogenization and Ecogeography on Regional scale in Manmade EcoSystems (HERMES) campaign which aimed to study biogeographic processes on regional scale along the whole Italian coast. We drove camper to sample urban and natural habitats on 33 sites in 2 months
Together with the previous works on local adaptation, this might indicate that some NIS species invest energy in disturbance resistance. As these investments are costly, this renders them less competitive in less disturbed areas, maybe explaining why many NIS stay restricted to urban habitats.
Robin P.M. Gauff@robingauff.bsky.social · last yr.A native mussel distributed along a gradient with lower abundance in the inner parts, while the invasive more resistant one did the opposite. Recruits matched this pattern for the native, but the invasive species recruits settled everywhere indicating post recruitment effects doi.org/10.3389/fmar...

Even more striking, is that local adaptation of some Bryozoa to local pollution is present on such a tiny scale (<100m). This is shown by higher pollution accumulation of Entrance-->Inner transplants compared to inner control (red boxes), and lower LysoPE content (fitness marker, white arrow).
Robin P.M. Gauff@robingauff.bsky.social · last yr.The difference in community structure between areas of the same marina can be actually quite striking as demonstrated by our settlement plates. We were able to causally link community and pollution via a transplant experiment.

We’re currently doing some field sampling in harbors and natural environments to test whether biotic homogenization happens on a temporal scale too! #fieldwork
In a new paper, we simulated a strong heatwave in a harbor, which did ... nothing! The community was unchanged, as was the metabolome of a Bryozoan. The harbor community showed high resistance which is consistent with observations from other disturbances doi.org/10.1016/j.marenvres.2024.106813
In marine urban habitats #pollution leads to strong variation in envir. conditions , thus, to differences in community structure. However this can be masked by high intensity marine #HeatWaves favouring resistant species leading to small scale biotic homogenization. doi.org/10.1016/j.je...
Climate change is affecting ecosystems worldwide, but remains difficult to study due to the difficulty of implementing in situ experiments. With our great team from @sbroscoff.bsky.social we constructed a system reliably simulating +3°C climate change on harbor communities doi.org/10.1007/s108...
