Lindström (in Trends Ecol Evol 14: 343–347, 1999) synthesized knowledge about “early
development and fitness in birds and mammals”, interesting tracks and challenges for future …

Exhibiting behavioral plasticity in order to mount appropriate responses to dynamic and
novel social environments is crucial to the survival of all animals. Thus, how animals …

Raptors are known for asymmetric parental roles, with the female brooding and feeding
offspring, and the male providing food, usually assisted by the female from the latter part of …

The genetic covariation among different traits may cause the appearance of correlated
response to selection on multivariate phenotypes. Genes responsible for the expression of …

Deciding when to terminate care of offspring is a key consideration for parents. Prolonging
care may increase fitness of current offspring, but it can also reduce opportunities for future …

Post-fledging care constitutes a large proportion of the total costs of parental care in many
bird species. Despite being recognized as of critical importance to the survival of the …

The cost of reproduction is a key concept in life-history trade-offs. However, our
understanding of the reproductive costs is biased towards measures of reproductive effort …

Raptors deviate from the norm among provisioning birds by having asymmetric parental
roles, with the female brooding and feeding offspring, and the male providing food, assisted …

Parental care has been widely studied in birds and mammals, but variation in space use in
family groups has received less attention, despite its potential importance for both survival …

Parental care typically enhances offspring fitness at costs for tending parents. Asymmetries
in genetic relatedness entail potential conflicts between parents and offspring over the …
