Overview

I am a behavioural and evolutionary ecologist with wide ranging interests that include parental care, sexual selection, mating systems, reproductive conflicts of interest, early and social environmental effects,  behavioural plasticity, social networks and life-history evolution and conservation. My work involves both invertebrate and vertebrate model systems in the field and in the lab, especially using Nicrophorus vespilloides burying beetles. I am a member of the Behaviour research group.

I am also the admissions tutor for Penryn Biosciences and am Chair of the CLES Penryn Ethics Committee.

Research interests

I’m a behavioural and evolutionary biologist interested in how organisms adapt to changes in their environment (social and/or non-social), with a particular current focus on behavioural plasticity in the context of parental care and sexual selection, within-family conflicts over parental investment and the co-evolutionary relationship between mating behaviours and parental care. I mostly use Nicrophorus vespilloides burying beetles in the lab or the field to address the questions that I am interested in, but also work on blue tits Cyanistes caeruleus in the field to look at the effect of anthropogenic noise on parent-offspring conflict and communication and have developing interests in ground beetle life-histories and conservation, particularly blue ground beetles Carabus intricatus

 

Research projects

Current (2018-19) and recent projects include:

Burying beetle projects

***Helpful beetles: Does inclusive fitness promote brood parasitism in burying beetles?***

Costly help can raise a relative's reproduction, survival, and reproductive value and increase the inclusive fitness of the donor of help. Donor fitness can be explored in the context of conspecific brood parasitism. In this alternative reproductive tactic, some females, "parasites," lay eggs in nests of other females of the same species, "hosts," suppliers of help that alone take care of the offspring. Theory predicts that hosts can gain inclusive fitness if parasitized by relatives whose reproduction or survival is thereby increased. This project will test these predictions using Nicrophorus vespilloides burying beetles, where such brood parasitism is common.

***Plastic beetles? Do male burying beetles differ in their behavioural plasticity across populations?***

Nicrophorus vespilloides burying beetles have complex love lives, including the provision of parental care alone or with a partner, and the expression of alternative reproductive tactics, both of which are behaviourally plastic in response to changes in their social environment (i.e. who they interact with and how). This flexibility in behaviour is related to the unpredictable availability of the resources they need for reproduction. They compete for, and breed on, the carcasses of small vertebrates. When males find a carcass they signal to attract females, but this can also attract other males. We have recently found that male burying beetles from different selection lines (populations) differ in the plasticity of their signalling and dominance behaviour on carcasses in response to competition with other males i.e., that there is a GxE for plasticity of signalling behaviour (see Carter et al. 2015 Evolution). This is important as it demonstrates that there is the potential for behavioural plasticity to evolve in response to selection. However, nothing is known about how populations of wild beetles differ in their behavioural plasticity in response to variation in the level of competition experienced. This project uses a combination of fieldwork to collect beetles from different populations across Cornwall and labwork to do common garden experiments to quantify the potential for GxE of plasticity of male reproductive behaviours in wild beetles.

***Are the benefits of male prenatal care only evident when microbial competition is high?***

Studies show that biparental care does not appear to be more effective than uniparental care and that prenatal care does not impact offspring fitness but postnatal care does in Nicrophorus burying beetles, but these experiments have largely been done under benign environmental conditions, so the potential benefits of male care may not be evident unless there is substantial microbial competition. This project tests this idea.

Blue ground beetles 

***Big blue: Habitat preferences and conservation of blue ground beetles***

Blue ground beetles Carabus intricatus are the largest species of UK ground beetle but are found at only a handful of sites, primarily on Dartmoor. They are a BAP priority species so have important conservation status. However, relatively little is known about their habitat requirements and preferences. Such knowledge is essential in order to be able to implement successful conservation practices to boost populations. This project aims to determine habitat preferences and population sizes of blue ground beetles in Devon and Cornwall in collaboration with Natural England.  

Blue tits

***The kids are not listening: Effects of anthropogenic noise on parental care in blue tits***

Anthropogenic sources of noise, such as roads, may have detrimental effects on reproductive success of species of birds with altricial young as a consequence of adverse effects on parent-offspring communication, but the empirical evidence is equivocal. This project aims to test the effects of road noise on parent-offspring communication and reproductive success in a nest-box population of blue tits breeding in broad-leaved woodland in Cornwall.

External Engagment and Impact

Editorial responsibilities

I edited a major book on The Evolution of Parental Care, published in 2012 by Oxford University Press and was an editor at the journal Behavioral Ecology from 2013-2016 and a section editor (2011-2013) and associate editor (2008-2011) at BMC Ecology.


External Examiner Positions

I have been an external examiner for PhDs at eleven different institutions, mostly abroad (UK – UEA, University of Bath, Queens University Belfast, Cambridge University, Edinburgh University; International – Mainz University, Aarhus University, Université Toulouse Paul Sabatier, Macquarie University, University of Basel, Wageningen University). I have also been an external examiner for the Masters programmes in the School of Life Sciences at the University of Liverpool (MSc and MRes). I have been doing this since 2014/15 and have just completed my final year (2017/18).

Media Coverage

My work has received widespread media coverage. For example, Hopwood et al. (2016a) has an Altmetric score of 273, which is (as of November 2018) the 5th highest of any paper published in Evolution (out of 3130 papers) and is comfortably in the top 0.5% of papers tracked for impact across all journals. Similarly, Hopwood et al. (2016b) is one of the highest scoring papers ever tracked for impact at the Journal of Evolutionary Biology (#5 out of 1830 papers). Numerous other papers have also received good press coverage. In particular Benowitz et al. (2013), published in Proceedings of the Royal Society B was featured in articles in The Times (print edition), The Daily Mail Online and on the BBC website and it was the ‘research finding of the month’ in BBC Wildlife magazine in August 2013.
