| Summary: | Trade-offs between current and future reproduction are central to the evolution of life histories. Experiments that manipulate brood size provide an effective approach to investigating future costs of current reproduction. Most manipulative studies to date, however, have addressed only the short-term effects of brood size manipulation. Our goal was to determine whether survival or breeding costs of reproduction in a long-lived species manifest beyond the subsequent breeding season. To this end, we investigated long-term survival and breeding effects of a multi-year reproductive cost experiment conducted on Black-legged Kittiwakes (Rissa tridactyla), a long-lived colonial nesting seabird. We used multi-state capture-recapture modeling to assess hypotheses regarding the role of experimentally reduced breeding effort and other factors, including climate phase and colony size and productivity, on future survival and breeding probabilities during the 16-year period following the experiment. We found that forced ... : KittiwakeLongTermReproductiveCostDatasetEncounter histories for kittiwakes used in a 1991-1994 cost of reproduction study and resighted at least once between 1995 and 2010. Encounter histories begin in 1994; because birds were actually banded in 1991, the first encounter is a simulated "release" as a breeder. Individuals were forced to fail in 0, 1, 2, 3, or 4 years, but since very few birds were manipulated four times, we included them with the "3" category. Quality designations are described in the manuscript. ... |
