I am a behavioural and evolutionary ecologist with wide ranging interests including parental care, sexual selection, reproductive conflicts of interest, early and social environmental effects, animal social networks, and behavioural plasticity. My work uses both invertebrate and vertebrate model systems in the field and in the lab, especially burying beetles. I am a member of the Behaviour research group.

Research

Research interests

I am interested in a variety of related topics within behavioural ecology including parental care, reproductive conflicts of interest, early and social environmental effects (particularly on the expression of secondary sexual traits), social networks, signalling and mate choice, consistency of behaviour (‘personality’), and the potential role of oxidative stress in mediating some of these effects.

Research projects

Nutritional environmental effects on parental care

NERC DTA studentship (2010-2013)
Parental effects occur whenever the expression of the phenotype of an individual is affected by the phenotype or environment provided by its parents. Consequently parental effects are dynamic components in the process of development that enables evolution through natural selection, through the reliable transferral of developmental resources needed by offspring. Adaptive parental effects depend particularly upon reliable cues that predict the offspring environment, and the selection pressures acting on parents and offspring. This project is assessing the downstream effects on offspring of variation in the level and predictability of the nutritional environment experienced at two key stages of development on the expression of adult traits in a model study organism, Nicrophorus vespilloides burying beetles.

The evolution of parental care roles

NERC standard grant to Allen Moore (2010-2013)
This project is examining how genetic architecture influences the direction of evolution and differences between the sexes in parental care, using Nicrophorus vespilloides as a model species. This work will help determine how sex roles evolve.

Costs of reproduction and the mechanistic basis of ageing in crickets

NERC DTA studentship (2008-2011)
This project is examining the effect of the availability of specific nutrients on sex differences in reproductive effort, cellular damage by reactive oxygen species (such as free-radicals and oxidants) and rates of ageing in the native Australian field cricket, Teleogryllus commodus. The project involves fieldwork in Australia in addition to controlled experiments in the laboratory.

Costs and consequences of trade-offs during growth in pheasants

NERC CASE studentship (2007-2010)
Variation in resource availability leads to resource allocation trade-offs during growth and development, and these may be particularly acute in species with strongly sexually-selected (carotenoid-based) traits. This project has investigated the role that antioxidants play in modulating resource allocation trade-offs during growth and development, and hence how they determine adult phenotypic characteristics.

Recent research projects

Costs and consequences of the structured family

NERC new investigator grant 2007-2008 (PI)
We examined the cost basis of trade-offs during growth through the manipulation of antioxidant availability and rearing environment, and the subsequent measurement of oxidative stress, in nestling red-winged blackbirds Agelaius phoeniceus. Individuals supplemented with dietary antioxidants allocated these extra resources to increasing growth rate rather than to maintenance (reducing oxidative damage). These novel results support the idea that the costs of rapid growth are mediated via a trade-off between growth and oxidative damage and highlight the importance of consideration of physiological costs in the evolution of life-history trade-offs. We also examined patterns of egg antioxidant deposition in an avian host-parasite system (red-winged blackbirds and their parasites, brown-headed cowbirds). We found evidence that cowbirds preferentially allocated alpha-tocopherol to their eggs, which is one of the most potent dietary-derived antioxidants and has positive effects on growth, and that the amount of alpha-tocopherol in cowbird eggs was closely correlated with that of the alpha-tocopherol content of their hosts. In contrast, cowbirds deposited low amounts of carotenoids and retinol, and there was no relationship between concentration of these antioxidants in cowbird and red-winged blackbird eggs. Maggie Hall was the PDRA.

Costs, consequences and context-dependency of intra-familial conflict

NERC postdoctoral fellowship (2005-2008)
The consequences of intra-familial conflicts can be pervasive, with important effects on the evolution and diversity of a range of life-history traits, such as growth rates, begging behaviour, clutch size and sexual attractiveness as adults. However, although the importance of intra-familial conflicts on growth, development and fitness are increasingly being recognised, very little is known about the behavioural mechanisms that underpin such conflicts, or the nature of the relationships between availability of environmental resources, delivery of and conflict over these resources, and their costs and consequences for fitness. This project aimed to disentangle and quantify these effects in zebra finches Taeniopygia guttata.

Signals of genetic quality in a genetically heritable social environment

NERC standard grant 2005-2008 (Co-PI)
In this study, we examined the role that competitive interactions between individuals during development played in producing variation in condition and, thereby, producing variation in condition dependent traits that are the target of mate choice. Using the stalk-eyed fly, Cyrtodiopsis dalmani as a model system, we utilized a statistical genetic model to estimate the relative importance of social interactions in producing genetic variation in male eye-span, which is the target of female preference and which has been shown to have condition dependent expression.
The project was in collaboration with Jason Wolf at the University Manchester (now at the University of Bath) and Jerry Wilkinson at the University of Maryland, USA. Ed Harris was the PDRA (now at Manchester Metropolitan University).

Editorial responsibilities

In addition to NERC grant and fellowship applications and grant applications from overseas bodies (e.g. NSHRF) I regularly review manuscripts for scientific journals, including: American Naturalist, Animal Behaviour, Auk, Avian Science, Behavioral Ecology, Behavioural Ecology and Sociobiology, Biology Letters, Biological Reviews, BMC Evolutionary Biology, Comparative Biochemistry & Physiology, Ecology, Ecology Letters, Evolution, Evolutionary Ecology, Functional Ecology, Ibis, Journal of Avian Biology, Journal of Animal Ecology, Journal of Evolutionary Biology, Oecologia, Oikos, PloS ONE, Proceedings of the Royal Society of London B, Wildfowl, Zebrafish.

I am a section editor for BMC Ecology and an editor for Behavioral Ecology. 

I have also edited a major book on The Evolution of Parental Care, published by Oxford University Press http://ukcatalogue.oup.com/product/9780199692583.do.


Invited lectures

I have given invited seminars at 8 UK Universities and 2 Universities outside the UK.


Media Coverage

My work receives regular, widespread coverage in the media. Recent examples include:

Recent work on parental care in burying beetles (Benowitz et al. 2013) published by Proceedings of the Royal Society B has received widepsread media coverage both in the UK (e.g. BBC http://www.bbc.co.uk/nature/22950923, The Daily Mail http://www.dailymail.co.uk/sciencetech/article-2344443/Older-men-make-better-fathers-tolerate-infidelity-BEETLE-world.html?ito=feeds-newsxml, The Times http://www.thetimes.co.uk/tto/science/article3795551.ece?CMP=OTH-gnws-standard-2013_06_19) and abroad (e.g. India  http://zeenews.india.com/news/science/older-male-burying-beetles-make-better-fathers_856078.html, USA  http://www.huffingtonpost.com/2013/06/19/older-males-better-fathers-beetle-study_n_3461808.html). It has also been chosen to feature as the 'research finding of the month' by BBC Wildlife magazine (http://www.discoverwildlife.com/).

Another recent paper, on personality in zebra finches, published in Biology Letters (Schuett et al. 2013) has also been widely reported in the media, including The Daily Mail http://www.dailymail.co.uk/sciencetech/article-2335681/Enviroment-stronger-genes-determining-personality.html, The Belfast Telegraph  http://www.belfasttelegraph.co.uk/breakingnews/offbeat/nurture-determines-personality-29320625.html, The Daily Telegaph, The Scotsman and numerous other print and online outlets in the UK, Europe and in Australia, India, Ireland and New Zealand. In addition I was interviewed about the paper on Talk Radio Europe and the research is scheduled to feature on over 60 radio stations across the USA and Canada as a slot on the Academic Minute http://www.wamc.org/programs/academic-minute.

My work on social networks in families of great tits published in Proceedings of the Royal Society B (Royle et al. 2012) resulted in an interview on BBC Radio Cornwall, and appeared in many online outlets and local papers (e.g. http://www.thisiscornwall.co.uk/Tweets-just-vital-birds-humans/story-17191906-detail/story.html#axzz2YAxJn646).
