Let us mourn, show compassion, and hold onto hope for better days and the immediate release of the hostages of October 7th.

This isn't about politics; this is about the basic right to human dignity and to live in security. And try explaining that to othersβ€”those distant, disconnectedβ€”that the situation is not simple at all, that the solution isn't slogans or clichΓ©s...

In those days, I asked myself, "Who even cares about ecology? Let the world go to hell; people are fighting for their lives." No child should have to grow up like this. And still, people are held captive in hell, while others fight for food. I will never forget October 7th.

Every other night, I wake up from a nightmare. And who would have believed that this nightmare isn't over?

After we came out, we understood the severity of the situation. Chaos all around. Hundreds murdered, raped, witnessing their family members killed beside them - children, grandparents, parents. People I knew are gone. Many are missing. A collective trauma that hasn't left my sleep to this day.

Two years ago today, just before dawn, my wife was next to me in bed, nursing our beloved daughter. She woke me: "Get up! Siren!" We rushed to the shelter. It was longβ€”so many explosions overhead. I knew quickly this wasn't routine; something extraordinary was happening.

I've been debating for a long time whether or not to share this publicly. I'm doing it now because I believe that only by sharing the raw, personal trauma may some understand that this isn't politicsβ€”it's about the basic right to life and dignity.

New data on 2023's marine heatwaves is alarming. Oceans hit unprecedented temps & durations, with some events so extreme they're considered once-in-centuries occurrences. It's a clear signal that warming climate impacts are accelerating.

Trump is stripping protections from marine protected areas – why that’s a problem for fishing’s future, and for whales, corals and other ocean life America’s marine protected areas help fish populations thrive. Trump’s plan to open them to industrial fishing may ultimately harm the fishing industry itself.

Claims by the Trump administration that marine protected areas are a heavy-handed restriction on the U.S. fishing industry do not hold water.

Science shows these refuges for sea life help local economies and allow fish populations to thrive

We show that marine communities around the world exhibit trophic convergence in similar environments β€” a global pattern echoing what we also found on land. This challenges classic biogeographic models and opens new doors for predicting biodiversity responses to change.

Interesting read on a core question in species redistribution research: abundance vs. occurrence data. Turns out, the choice really matters – authors show that they lead to different estimates. πŸ€” onlinelibrary.wiley.com/doi/10.1111/...
