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. 🧪

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).

New paper introducing the term of SUPER HABITAT for sharks in which all critical activities (resting, feeding, mating & giving birth) occurs.

‼️ New important shark paper 🦈
We demonstrate that all critical life stages (resting, feeding, being cleaned, mating & giving birth) can occur in the small Fakarava channel & we define it as a “super habitat”

New paper in Ecology & Evolution: analysed 187 species of rays & skates to explore patterns of sexual size dimorphism. Turns out SSD in rays doesn’t follow the same rules as in sharks.

❓Differences in reproductive strategies❓
