1.目前的研究探讨了大规模的气候和个人特定的协变量对巢生存在smallmouth鲈鱼超过20年的时间。2.大规模的气候指数[冬季北大西洋涛动（NAO）和冬季厄尔尼诺/南方涛动（ENSO）]和父母的男性的身体大小是重要的协变量在巢存活沿着与巢龄和生存的二次趋势。3.我们没有发现由于栖息地协变量（总有效取）或物候协变量（筑巢开始时的天数）对巢生存的影响。4.男性大小在下半年的筑巢季节是一个更有影响力的协变量巢成功比男性大小在上半年或整个筑巢期间。5.我们目前的证据表明，冬季NAO/ENSO指数建立湖泊条件下的春天，影响热稳定性的湖泊在筑巢期间。6.结合气候和身体大小的协变量指向巢生存滞后的气候尺度的影响，湖沼学和个人规模的影响，对父母的照顾和巢成功的持续时间。
1. The current study examined the effect of broad-scale climate and individual-specific covariates on nest survival in smallmouth bass over a 20-year period. 2. Large-scale climate indices [winter North Atlantic Oscillation (NAO) and winter El Niño/Southern Oscillation (ENSO)] and body size of parental males were important covariates in nest survival along with nest age and a quadratic trend in survival. 3. We did not find an effect due to a habitat covariate (total effective fetch) or a phenology covariate (degree-days at start of nesting) on nest survival. 4. Male size in the second half of the nesting season was a more influential covariate on nest success than male size in the first half or throughout the nesting period. 5. We present evidence showing that winter NAO/ENSO indices establish limnological conditions the following spring that influence thermal stability of the lake during the nesting period. 6. The combined climate and body size covariates point to nest survival as a function of lagged climate-scale influences on limnology and the individual-scale influence of bioenergetics on the duration of parental care and nest success.
