摘要

后代的供给可作为资源获取的替代物,并随父母的性别和年龄而变化。与年龄相关的变化可能源于个体经验和衰老,也可能源于劣质亲本的选择性消失。要区分这些过程并量化它们对个体雏鸟的资源获取和命运的影响,需要对已知年龄的个体进行纵向监测,而这种情况仍然很少见。在我们的纵向研究中,我们观察了普通燕鸥(Sterna hirundo)6年的后代供给情况,并从亲代和后代的角度分析了供给行为。通过重复测量单个亲鸟的供养行为,我们的分析表明,供养行为并不随着年龄的增长而增加,但观察到的年龄越大的亲鸟供养行为越多,这表明供养行为较少的亲鸟选择性地消失了。雄性亲鸟的供养率高于雌性亲鸟,而且雌雄亲鸟的供养率都随着育雏规模的增加而增加。对后代而言,能量获取随孵化顺序而减少,随年龄而增加。随着雏鸟年龄的增长,从母亲那里获得的能量比从父亲那里获得的能量增长得更快,而且母亲在不同孵化顺序的雏鸟身上的供给分配更均匀。然而,父母的年龄并不影响后代的能量获取。雏鸟的早期能量获取率可预测其羽化成功率,但不能预测羽化质量。当把对能量供给和获取率的影响分解为对摄食率、猎物能量密度和猎物大小的影响时,我们发现所有影响都来自摄食率的变化。总之,这些结果表明,亲代和子代的质量都有差异,这反映在它们的摄食率上。

Feeding rate reflects quality in both parents and offspring: a longitudinal study in common terns

Offspring provisioning can act as a proxy of resource acquisition and vary with parental sex and age. Age-related variation can arise from individual experience and senescence, but also from selective disappearance of poor-quality parents. Distinguishing between these processes and quantifying their effect on the resource acquisition and fate of individual chicks requires longitudinal monitoring of known-age individuals, which is still rare. In our longitudinal study, we observed offspring provisioning of common terns, Sterna hirundo, across a 6-year period and analysed provisioning behaviour from both a parental and offspring perspective. Using repeated measures of provisioning of individual parents, our analyses showed that provisioning did not increase with age, but that parents that were observed at older ages provisioned more, suggesting selective disappearance of parents that provisioned less. Parental provisioning was higher in males than females and increased with brood size in both sexes. For offspring, energetic acquisition declined with hatching order and increased with age. Acquisition from the mother increased faster with chick age than that from the father, and mothers distributed their provisioning more evenly across chicks of different hatching order. Parental age, however, did not affect the energetic acquisition of the offspring. The early energetic acquisition rate of chicks predicted their fledging success, but not fledging mass. When decomposing effects on energetic provisioning and acquisition rate into effects on feeding rate, prey energetic density and prey size, we found that all arose from variation in feeding rate. Overall, these results therefore show that both parents and offspring vary in quality, which is reflected in their feeding rate.

期刊介绍: Growing interest in behavioural biology and the international reputation of Animal Behaviour prompted an expansion to monthly publication in 1989. Animal Behaviour continues to be the journal of choice for biologists, ethologists, psychologists, physiologists, and veterinarians with an interest in the subject.
