Broad research specialisms

My research focusses on studies of mechanism and function in animal ecology. I have three main interests: (1) behavioural and evolutionary ecology of animal signalling; (2) nutrition ecology; and (3) oxidative stress and the biology of ageing. Some of the work carried out in my group addresses these topics in isolation. For example, we study predator-prey interactions in relation to aposematic (warning) signals, mimicry and chemical defences. In other work we study the mechanistic basis of ageing. However, there are interesting linkages between animal signalling, nutrition and oxidative stress at the physiological level. As such, many of our current projects are highly integrative and include studies of behaviour and underlying biochemical and molecular mechanisms. Much of my work focuses on basic research, but I am also interested in how an understanding of mechanism and function can help tackle applied questions in conservation biology. I work on a broad range of species in the field and the lab. I am a member of the Behaviour research group.

Current�research projects:

 

Transgenerational costs of reproduction and the evolution of life histories

The assumption that investment in reproduction reduces lifespan is a cornerstone of life history theory. Oxidative damage has been proposed as a mechanism underlying the cost of reproduction, but tests of this idea have proved equivocal. We have suggested that previous results can be explained if oxidative damage has impacts not only on an individual breeder's fitness, but also on the fitness of their developing offspring (Blount et al. 2016 Biol. Rev. 91, 483-497; Vitikainen et al. & Blount 2016 Front. Ecol. Evol. 4, 58). Such trans-generational costs of reproduction could have a profound influence on life history evolution, but there is currently little theory or data to evaluate this hypothesis. We are currently developing a new theoretical framework to incorporate trans-generational impacts of oxidative damage into life history theory, and testing the assumptions and predictions of our models in a tractable wild mammal system - our long-term study population of banded mongooses (Mungos mungo) in Uganda. This work is funded by a NERC standard grant to JD Blount, MA Cant and RA Johnstone.

 

Evolutionary ecology of aposematism

Many prey species use conspicuous warning signals to advertise the fact that they are defended (i.e. aposematism).�We are interested�in�the mechanisms which underpin variation in aposematic signals and chemical defences. Currently funded projects in my group focus on the developmental ecology of aposematic traits in green and black poison dart frogs; honest�signalling in ladybird beetles; and the costs of chemical defences in monarch butterflies.

The price of defence - fitness consequences of intraguild predation amongst ladybirds

The harlequin ladybird (Harmonia axyridis) is an alien invader in Europe, and being highly competitive and polyphagous, it poses a serious threat to other aphidophagous insects. Native/naturalised ladybird species may deter harlequins from preying on their eggs and larvae by investing in chemical defences, but such investment could carry serious costs. One possibility which this project is investigating is that individuals face a trade-off in the allocation of resources to the production of well-defended offspring versus the maximisation of offspring number per se.

 

Interested in joining us?

Underpinning these interests I have analytical expertise in the use of HPLC, LC-MS and GC-MS techniques, for example to assay biological pigments, toxins, and nutrients. Please contact me with any queries about facilities available in our Metabolomics Lab.

I am always keen to hear from students or postdocs who are interested in research that combines studies of behaviour and physiological mechanisms. If you are interested in joining my research group, please get in touch by email (j.d.blount@exeter.ac.uk).
