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
… that competition causes resource specialisation. Burying beetles are an ideal species for testing this prediction. They require the carcass of a small vertebrate such as a mouse or a songbird for reproduction, but carcasses can be unpredictably distributed and competition to secure ownership is …

Evolution in a fragmented world: Phenotypic and genetic divergence amongst neighbouring populations of the burying beetle Nicrophorus vespilloides
… problem using neighbouring 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 …

On the ecological transitions between parasitism and mutualism
… between parasitism 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 …

The social environment and the evolution of morphology in the burying beetle, <em>Nicrophorus vespilloides</em>
… a combination of 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 …

The role of parents in Evolution
… an experimental approach, 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 …

Social Evolution in Action: Causes and Consequences
… trait 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 …
