The mathematics of starvation: how Israel caused a famine in Gaza Israel controls the flow of food into Gaza. It has calculated how many calories Palestinians need to stay alive. Its data shows only a fraction has been allowed in

It cannot be denied: this is a deliberate and coldly-calculated famine, engineered by a technologically-advanced state which knows exactly what it is doing.

Hi Ryuta, we are putting together a global network on traits of canopy-forming macroalgae. We are currently looking for participant based in Japan. Would you be potentially interested? If so, please add me, share your email, and I can DM/email more information.

πŸ“‘ #NewStudy by Marinovich et al. investigates how the gape size of snapper affects the size of sea urchins they eat.

This adds more knowledge to the ecosystem interactions between fish, urchins and the transformation of habitat from seaweed forest to urchin barrens.

How can the world just keep ignoring this? I just don't get it, I really don't.

This is the systematic destruction of a country and its people.

It is genocide, and it has been for a very long time now.

We had a really positive experience publishing in an AoB special issue a few years back. Robust reviews and editing and ultimately a great venue for the work. Highly recommended. Deadline for this exciting SI is end of November.

We studied intertidal fish communities in Iceland & the effects of Ascophyllum nodosum harvesting.

Juvenile gadoids relied on these habitats and harvesting showed subtle effects on fish size & diet.

I’m obsessed with brittle stars: fish often nip off bits of their arms but they regenerate These starfish relatives have lots of remarkable features and are a keystone species. My hope is that we will recognise how vital these charismatic creatures are

There is no justification whatsoever for the US or UK to provide any support, material or diplomatic, for Israel's attack on Iran. It is a war of aggression, clearly contrary to international law.

A recent study uncovers a trophic cascade after great white sharks disappear β€” Dr. Jack A. Cooper Great white sharks are known to be top-level predators in the marine food web. But what happens when we lose that predator from a marine ecosystem? An ongoing case study in South Africa is highlighted...

Pleased to share my first website blog!

We've seen great white sharks disappear in South Africa; whether down to orcas or something else. What effects do we see when this apex predator is lost? Well, a recent study answered it 🦈
