Gen Comp Endocrinol : 32 — Google Scholar. Here, we provide the most comprehensive assessment of these hypotheses using detailed parental care data from bird species covering families. Finally, a long standing question is why one parent cares for the offspring when the other does so already, i.
Parentage and the evolution of parental behavior. Cryptic kin selection: kin structure in vertebrate populations and opportunities for kin-directed cooperation. Neural correlates of nesting behavior in zebra finches Taeniopygia guttata.
However, because a reduction in adult survival reduces future reproductive opportunities, there is also an indirect trade-off between care and future reproduction for both sexes. Hierarchical decision-making balances current and future reproductive success.
By our definition, egg survival increases as initial egg investment increases.
The honey bee epigenomes: differential methylation of brain DNA in queens and workers. Habitat saturation results in joint-nesting female coalitions in a social bird. Isotocin regulates paternal care in a monogamous cichlid fish.
Gen Comp Endocrinol : 32 — Princeton : Princeton University Press. Nat Ecol Evol 2 : — Baseline adult mortality also affects the fitness gains associated with parental care Fig.
We are interested in differences in the life-history conditions that favor the origin of paternal, maternal, and bi-parental care, and thus, we focus on cases in which care is beneficial and likely to be selected for. Delayed dispersal: youth costs carry lifetime gains.
