Tolerance is optimised by being well connected within the network, whereas support requires strong relationships with a few reliable partners.

Different socio-ecological contexts should therefore select for investment in quality, quantity, or some optimal balance of both.
Heat map showing how the need for tolerance and the need for social support shape investment in relationship quantity and quality.

Other challenges, like coalition formation in contest competition, require more costly social support from partners willing to incur those costs.

Social relationships have evolved because they help animals cope with challenges in their environments.

Some challenges can be met simply by being tolerated by others - like the safety in numbers that reduces predation risk.

Social relationships are powerful predictors of fitness across social animals. But *why*?

In our new @cp-trendsecolevo.bsky.social paper, we outline testable predictions for why relationship quality and quantity adaptively vary across socio-ecological contexts.

The Adaptive Relationships Framework illustrating how broad socioecological pressures shape the social solutions animals use to meet these challenges, and how these lead to social strategies and emergent structures that help them gain access to those solutions.

Rohini Balakrishnan gave a wonderful plenary talk on tree crickets, showcasing the power of combining field and experimental research, with some very neat findings—males use leaves to amplify their calls, and more so on days when their calls are less loud! 😮

Susan Alberts & @samellisq.bsky.social gave beautiful plenary talks showcasing the Amboseli baboons @amboselibaboonrp.bsky.social & Southern resident killer whales @whaleresearch.bsky.social - excellent examples of the value of long-term research and the insights we can gain from them.
