Caching Behavior In Burying Beetles, Stephen T. Trumbo
Caching Behavior In Burying Beetles, Stephen T. Trumbo

Being the first to discover a resource can provide a competitive advantage (priority effect), even for an animal that is inferior in aggressive contests. Nicrophorus spp. (burying beetles) are known for caching a small vertebrate carcass as provision for their young, reducing volatile cues available to rivals by burying the carcass (vertical movement) and by altering the microbial community. A decomposing carcass, however, can leave cues (residues of decay) on soil and leaf litter that a burying beetle has less opportunity to neutralize. I investigated whether horizontal movement of the carcass by burying beetles, separating the carcass from soil at …

Data Set: Comparative Parental Care In Carrion Beetles, Stephen T. Trumbo, Derek S. Sikes
Data Set: Comparative Parental Care In Carrion Beetles, Stephen T. Trumbo, Derek S. Sikes
EEB Articles
Comparative experimental study of species can provide insight into behavioral transitions in evolution. The insects offer many such examples for the analysis of parental care. We examined three species of Nicrophorus and two non-Nicrophorus silphid beetles for their ability to conceal a small carcass from competitors. We predicted that species with well-developed parental care would exhibit a heightened ability to conceal a resource from competitors, even when differences in burying behavior were experimentally eliminated. Carcasses were provided to male-female pairs in the laboratory for three days and then experimentally buried in the field, without parents, to assess discovery by …
