Isotocin regulates paternal care in a monogamous cichlid fish.
While the survival value of paternal care is well understood, little is known about its physiological basis. Here we investigate the neuroendocrine contributions to paternal care in the monogamous cichlid, Amatitlania nigrofasciata. We first explored the dynamic range of paternal care in three experimental groups: biparental males (control fathers housed with their mate), single fathers (mate r...
متن کاملNeural control of maternal and paternal behaviors.
Parental care, including feeding and protection of young, is essential for the survival as well as mental and physical well-being of the offspring. A large variety of parental behaviors has been described across species and sexes, raising fascinating questions about how animals identify the young and how brain circuits drive and modulate parental displays in males and females. Recent studies ha...
متن کاملControl of Fair Division
We initiate the study of control actions in fair division problems where a benevolent or malicious central organizer changes the structure of the fair division problem for self-interest or to benefit one, some or all agents. One motivation for such control is to improve fairness by minimally changing the problem. As a case study, we consider the problem of adding or deleting a small number of i...
متن کاملA Local Maximum in Gibberellin Levels Regulates Maize Leaf Growth by Spatial Control of Cell Division
Plant growth rate is largely determined by the transition between the successive phases of cell division and expansion. A key role for hormone signaling in determining this transition was inferred from genetic approaches and transcriptome analysis in the Arabidopsis root tip. We used the developmental gradient at the maize leaf base as a model to study this transition, because it allows a direc...
متن کاملPaternal chromosome segregation during the first mitotic division determines Wolbachia-induced cytoplasmic incompatibility phenotype.
The most common Wolbachia-induced phenotype in insects is cytoplasmic incompatibility (CI), which occurs when sperm from infected males fertilize eggs from uninfected females. CI produces distinct phenotypes in three closely related haplo-diploid species of the genus Nasonia: mortality in N. longicornis and N. giraulti, and conversion to male development in N. vitripennis. We demonstrate that t...
