Recognition in burying beetles (Nicrophorus spp., Silphidae, Coleoptera)
Burying beetles (Nicrophorus spp.) meet potential partners on carcasses. The aim of this study was to determine how males and females are able to determine potential partners from individuals of different species. The cuticular hydrocarbons of various species of European and Canadian burying …

Physiological bases of parental care in the burying beetles, Nicrophorus orbicollis
<p>Burying beetles, Nicrophorus orbicollis, have extended biparental care. They bury and prepare small vertebrate carcasses as food for their young. While females provide the most care, single males show a remarkable behavioral compensation after a mate loss. Here, I integrate behavioral and …

Ecological and molecular basis of differential resource use in populations of burying beetles Nicrophorus vespilloides
… of a bias in the type of carcass favoured by Nicrophorus vespilloides and if this bias changed across the burying beetle season (from April to October each year). I found spatial and seasonal variation within each of the three populations in the preference for dead mice over dead birds. In two …

The social environment and the evolution of morphology in the burying beetle, <em>Nicrophorus vespilloides</em>
… observation and experiments on burying beetles *Nicrophorus vespilloides*. This species exhibits a set of social interactions at all life stages that centre around the acquisition and use of small carrion during reproduction. Larvae grow and develop on an edible carrion nest fashioned from a …

Evolution in a fragmented world: Phenotypic and genetic divergence amongst neighbouring populations of the burying beetle Nicrophorus vespilloides
… wild populations of burying beetles (*Nicrophorus* spp.), insects which fight to secure carrion upon which they breed. My work focused on the *Nicrophorus* populations inhabiting a cluster of seven ancient woods west of Cambridge. Whilst the criteria used to identify ancient woods are …

Distribution of Carrion Beetles (Coleoptera: Silphidae) in Different Geographic Regions of Virginia
… of the state, with a special consideration for Nicrophorus species. The seasonal abundance and diversity of silphid beetles in Montgomery County, Virginia, was also examined. Baited pitfall traps were used to sample beetle distribution and abundance, and were placed in each of the five …

The role of parents in Evolution
… and focused on the burying beetle, $\textit{Nicrophorus vespilloides}$. The burying beetle is a perfect system for this question: they exhibit elaborate biparental care which is correlated with rapid speciation in the $\textit{Nicrophorus}$ genus. I started with a thorough exploration of …

On the ecological transitions between parasitism and mutualism
… and mutualism, using the burying beetles (Nicrophorus vespilloides) and their phoretic mites (the species complex Poecilochirus carabi) as a model symbiosis. I begin by showing that P. carabi is the most abundant mite species associating with burying beetles, and that it coexists with the …

Social Evolution in Action: Causes and Consequences
… loss and trait evolvability. The burying beetle *Nicrophorus vespilloides* represents an excellent system for investigating these consequences of parental care. This species exhibits elaborate but variable biparental care, whereby both parents prepare an edible nest for their young from a small …
