Filial cannibalism in a paternal mouthbrooding fish in relation to mate availability
Article Abstract:
The filial cannibalism in mouthbrooding males of the cardinal fish, Apogon doederleini, in southern Japan is related to the mating techniques of females that reduce inter-spawning intervals by changing mates. This cannibalism occurs within a day of spawning. Males prefer to eat broods produced by smaller and non-resident females. They change mates after cannibalism, and re-mate faster than males whose broods are removed. Cannibalistic males are able to indulge in multiple mating by eating their first brood and rearing the next one.

Pup contact promotes paternal responsiveness in male meadow voles
Article Abstract:
Analysis of social factors affecting paternal responsiveness and suppression of infanticide in male meadow voles, Microtus pennsylvanicus, tested with unrelated pups shows that pup exposure enhances paternal responsiveness. Rearing of pups as neonates with their fathers increases the responsiveness of adult males to pups. Intense exposure to pups is associated with diminished aggression and increased paternal responsiveness. Copulation and female contact do not influence male responsiveness to pups.
