A test of Hamilton's rule: cannibalism and relatedness in beetles
Article Abstract:
A study was conducted to investigate the correlation between cannibalistic behavior and relatedness in willow leaf beetles. Data were based on the cannibalism rate and relatedness of 74 beetles from 198 clutches. An analysis of data using statistical methods failed to provide a positive relationship between cannibalism and relatedness. This suggests that other factors such as competition, conflicts within the population and selection, influenced the cannibalistic behavior exhibited by beetles.

Pathogen transmission as a selective force against cannibalism
Article Abstract:
The contention that cannibalism is rare because of the significant cost of disease transmission to the predator is investigated by feeding cannibalistic tiger salamanders larvae with diseased heterospecifics, healthy heterospecifics, diseased conspecifics and healthy conspecifics. Larvae fed with diseased conspecifics had lower fitness compared with those fed with diseased heterospecifics. These results suggest that pathogen transmission is a significant drawback in cannibalism.

Parental care improves offspring survival and growth in burying beetles
Article Abstract:
The benefits of parental behavior in burying beetles of the genus Nicrophorus were examined as well as their effects on larval survival rates and final body mass. Results revealed that parental presence improved larval survival rates from the period immediately after hatching and after several days resulting in greater final mass of individual larvae. Larval growth and survival also improved with parental preparation of carcasses that allowed easy access of food for larvae.
