Win-stay/lose-switch, prospecting-based settlement strategy may not be adaptive under rapid environmental change

Abstract Understanding animal responses to environmental change is crucial for management of ecological traps. Between-year habitat selection was investigated in red‐necked grebes (Podiceps grisegena) breeding on semi-natural fish ponds, where differential stocking of fish created contrasting yet po...
