Potential causes of shedding aggregations in prairie rattlesnakes
Emily Martin, Courtney J. Conway
2026, Ecology and Evolution (16)
Aggregation is common across taxa and typically confers clear benefits to group members (e.g., allo-parenting, group defense, thermoregulation, access to resources). But aggregation can also be costly. The mechanisms that underpin aggregation—and the cues that elicit it—inform our understanding of how animals resolve tradeoffs among selection pressures. Snakes sometimes form...
