Human growth in early life has major implications for fitness. During this period, the mother
regulates the growth of her offspring through placental nutrition and lactation. However …

The Barn Swallow is a familiar and popular bird throughout the world. It is one of the most
widely distributed bird species, breeding in North America, Europe, Asia and North Africa …

Traits related to fitness are often pleiotropically linked or otherwise constrained in their
expression. Organisms therefore trade between fitness components such as number and …

Birds raise their young under constant risk of predation, which shapes how parents and
young communicate acoustically. Nestling begging calls extract care from parents but …

Background Environmental stressors increase the secretion of glucocorticoids that in turn
can shorten telomeres via oxidative damage. Modification of telomere length, as a result of …

In altricial avian species, nutrition can significantly impact nestling fitness by increasing their
survival and recruitment chances after fledging. Therefore, the effort invested by parents …

I of this perspective were “Sibling rivalry in nestling birds,” readers could hardly be faulted for
expecting a traversal of welltrodden ground. We have come to think of conflict among avian …

In some passerines, parents allocate more food to offspring with the brightest red gapes, but
the function of parental decisions based on offspring gape coloration is unknown. We …
