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 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 for investigating the causes and consequences of social and behavioral evolution.

The present study reports new behavioral records for Oxysternon palemo Castelnau, 1840 in Cerrado. According to its nesting habits and resource allocation, this species of dung beetle is traditionally classified as coprophagous and paracoprid, transporting portions of dung through tunnels excavated below the resource. We observed a male individual moving a pequi seed (Caryocar brasiliensis Cambess.

The existence of life-history trade-offs is a fundamental assumption of evolutionary biology and behavioural ecology, yet empirical studies have found mixed evidence for this. Such trade-offs are expected when individuals vary in how they allocate their limited resource budgets between different life-history functions (variation in resource allocation), but they may be masked when individuals vary in how many resources they have acquired that they can later allocate to life-history functions (variation in resource acquisition). We currently lack studies on the extent to which individual differences in behaviour reflect variation between individuals in resource acquisition and resource allocation.

Small vertebrate carcasses represent critical resources for many terrestrial organisms, including burying beetles, which rely on carcasses for survival and breeding. Carcass attributes can influence the reproduction of burying beetles, yet most studies on their breeding ecology have used laboratory-reared carcasses of limited sizes. We conducted breeding and feeding experiments using a wide size range of lab (laboratory mice) and wild carcasses (wild mammals, birds and reptiles) to investigate how carcass size, source and taxon affect various breeding outcomes (e.

By manipulating resource availability on a local spatial scale, we studied seasonal patterns of resource use within natural populations of burying beetles in a Norfolk woodland. Burying beetles are necrophagous insects that breed on vertebrate carcasses.
