Climate change and commercial fishing practices codetermine survival of a long‐lived seabird
Understanding the environmental mechanisms that govern population change is a fundamental objective in ecology. Although the determination of how top‐down and bottom‐up drivers affect demography is important, it is often equally critical to understand the extent to which, environmental conditions th...

Understanding the environmental mechanisms that govern population change is a fundamental objective in ecology. Although the determination of how top‐down and bottom‐up drivers affect demography is important, it is often equally critical to understand the extent to which, environmental conditions that underpin these drivers fluctuate across time. For example, associations between climate and both food availability and predation risk may suggest the presence of trophic interactions that may influence inferences made from patterns in ecological data. Analytical tools have been developed to account for these correlations, while providing opportunities to ask novel questions regarding how populations change across space and time. Here, we combine two modeling disciplines—path analysis and mark‐recapture‐recovery models—to explore whether shifts in sea‐surface temperatures (SSTs) influenced top‐down (entanglement in fishing equipment) or bottom‐up (forage fish production) population constraints over 60 years, and the extent to which these covarying processes shaped the survival of a long‐lived seabird, the Royal tern. We found that hemispheric trends in SST were associated with variation in the amount of fish harvested along the Atlantic coast of North America and in the Caribbean, whereas reductions in forage fish production were mostly driven by shifts in the amount of fish harvested by commercial fisheries throughout the North Atlantic the year prior.
