Revisiting the ecology and evolution of burying beetle behavior (Staphylinidae: Silphinae)

Abstract

Investigating fundamental processes in biology requires the ability to ground broad questions in species‐specific natural history. This is particularly true in the study of behavior because an organism's experience of the environment will influence the expression of behavior and the opportunity for selection. Here, we provide a review of the natural history and behavior of burying beetles of the genus Nicrophorus to provide the groundwork for comparative work that showcases their remarkable behavioral and ecological diversity. Burying beetles have long fascinated scientists because of their well‐developed parenting behavior, exhibiting extended post‐hatching care of offspring that varies extensively within and across taxa. Despite the burgeoning success of burying beetles as a model system for the study of behavioral evolution, there has not been a review of their behavior, ecology, and evolution in over 25 years. To address this gap, we leverage a developing community of researchers who have contributed to a detailed knowledge of burying beetles to highlight the utility of Nicrophorus for investigating the causes and consequences of social and behavioral evolution.

Abstract

Burying beetles of the genus Nicrophorus are becoming a model system for the evolution of parental care. Investigating fundamental processes in biology requires the ability to ground broad questions in species‐specific natural history. Here, we leverage a developing community of researchers who have contributed to a detailed knowledge of burying beetles to highlight the ecology and evolution of Nicrophorus, and the utility of this genus for investigating the causes and consequences of social and behavioral evolution.
