The number of individuals in a given space influences animal interactions and network dynamics. Here the authors identify general rules underlying density dependence in animal networks and reveal some fundamental differences between spatial and social dynamics. 🧪 www.nature.com/articles/s41...

Celebrating the publication of our big collaborative spatial-social meta-analysis of density-dependent transmission effects, out now in Nature Eco Evo! doi.org/10.1038/s415... (or rdcu.be/eD6eB)

Happy that my shark data contributed to this collaborative paper brilliantly led by @gfalbery.bsky.social on animal social networks. Out in @natecoevo.nature.com If density drives greater network connectedness, >80% of relationships are nonlinear (75% with saturating trends). Read: rdcu.be/eD6eB

Just back from the field for the start of our new project NETFISH using @lotektelemetry.bsky.social high-resolution telemetry to track small coastal fishes of the Mediterranean including damselfish. We deployed an array of receivers and next week we will be back for tagging ~100 fishes. More soon...

I will forever be haunted by this footage. Trawling has only been filmed underwater a few times in documentary history, and never with such clarity. What’s so heart-rending about these shots is watching how the animals don’t just get swept up — they swim for their lives. 🌎🦑🧪
