Investigating the Dynamic Interactions of Rapidly Growing Precocial Shorebird Chicks
Organisms in dynamic environments must continually reassess the cost-benefit trade-offs of their interactions and adjust their behaviors accordingly. Nevertheless, ecological research often takes a ‘snapshot’ approach to studying interactions across sample locations and timepoints. Investigating...

Organisms in dynamic environments must continually reassess the cost-benefit trade-offs of their interactions and adjust their behaviors accordingly. Nevertheless, ecological research often takes a ‘snapshot’ approach to studying interactions across sample locations and timepoints. Investigating ecological interactions in this way can miss important information about the influence spatiotemporal context has on the scale and direction of their effects. Longitudinal studies that follow individuals can elucidate how changing contexts affect an individual’s ecology while deepening our understanding of adaptive behavior. However, determining how context influences the effect of an interaction requires it be measured across a range of spatiotemporal conditions. Studying an animal’s ecology during periods of rapid change, such as early life development, could be a means of observing an interaction across multiple contexts on a short timescale.
