Thanks, Tom. In some ways, this is the paper we always had in mind when we started the big radar project. It's taken 8 years, but it's fantastic to see it out in the world.

🏙️ Surprisingly, urban areas are hotspots for nocturnal arthropods, possibly due to light attraction.
📊 This is one of the first national, high-resolution monitoring of both diurnal and nocturnal aerial arthropods using a single method—opening new doors for biodiversity tracking and conservation.

🌍 Abundance increases in the south, declines in the north—linked to temperature gradients.
🌳 Positive associations with #woodland, #grassland, and #urban areas.
🚜 Negative impacts from arable land and artificial light at night (ALAN)—especially on diurnal species.

We used UK weather radars to monitor aerial arthropod abundance across 35,000 km² over 8 years.
🔍 Key Insights:
🦋 Over 10 trillion arthropods fly above the UK daily during peak seasons.
🌙 Nocturnal arthropods show a national decline, while diurnal species remain stable but vary regionally.

I don't know why that was the image that the link produced... It was automatic!

We identified Fraser’s dolphins swimming over 400 km between Caribbean islands. This shows strong ecological connectivity—but also highlights the need for joined-up conservation.
Dolphins don’t recognise national borders—neither should marine policies.

A remarkable 83% of Fraser’s dolphin sightings were with other species—like sperm whales and spotted dolphins. They had the highest co-occurrence rate of any Caribbean cetacean.
Why? We think interspecies foraging may hold the key.

Using 4 years of data, we mapped the habitat of Fraser’s dolphins in the Caribbean. They prefer steep slopes, deep waters (500–1750 m), and areas close to underwater canyons. Ocean currents also shape their distribution. This work highlights key zones for marine conservation.
