Biography

I did my degree in Natural Sciences (Zoology) at the University of Cambridge, and then a PhD in behavioural ecology at the University of Glasgow.  I spent two years on a Killam Postdoctoral Fellowship at the University of British Columbia, followed by a Junior Research Fellowship at Jesus College, Cambridge.  I joined the University of Aberdeen as a Royal Society University Research Fellow in 2006, and was awarded a personal research Chair in Population & Evolutionary Ecology in 2014.

My research aim is to understand the genetic and environmental causes of variation in individual life-histories, and to understand the consequences of such variation for population and evolutionary dynamics. I achieve these aims by applying sophisticated statistical, quantitative genetic and molecular genetic analyses to long-term data from wild populations, coupled with mathematical and simulation modelling, and thereby develop and test ecological and evolutionary theory. At present, my main interests are in mating system evolution (especially inbreeding and polyandry) and eco-evolutionary dynamics driven by seasonal migration.

I am committed to actively translating my research into public understanding and conservation management policy, and aim to foster processes that link science and policy outcomes.

Research Interests

For full details of publications see 'Further Info'.

My overall research aims are to understand how variation in individual life-histories arises as a function of ecological, environmental and genetic variation, and to understand the consequences of such variation for the structure and dynamics of natural populations. This work is key to understanding, predicting and managing population responses to environmental variation and change.

I have a broad, integrative approach to addressing these questions, in which I aim to harness and advance rigorous theory and analytical methods spanning evolutionary ecology, population ecology, conservation ecology and behavioural ecology and thereby utilise field data to elucidate ecological and evolutionary outcomes. 

Summary of current major projects (further details are below):

1) Evolutionary ecology and quantitative genetics of polyandry, inbreeding and fitness: Mating systems provide one key mechanism that translates ecological and social interactions into evolution, yet we still do not understand the forces that drive and constrain mating system dynamics in nature. I am developing and applying sophisticated quantitative genetic analyses to an amazing long-term, multi-generation, dataset from song sparrows, alongside simulation modelling, to identify drivers and constraints on fitness in interacting females and males, and thereby test key hypotheses regarding (co)evolution of mating systems involving polyandry (female multiple mating) and inbreeding (matings among relatives). Current funding: European Research Council Starting Grant.

2) Eco-evolutionary dynamics in spatially-structured seasonally-mobile populations: The ability of populations to persist in the face of rapid environmental change will depend on the joint potentials for phenotypic plasticity and rapid micro-evolutionary change in key traits that mediate environment-demography interactions and hence shape population dynamics. Yet, such processes have scarcely been considered with respect to a critical trait that directly links population and evolutionary dynamics in seasonally-varying environments: reversible seasonal migration. Consequently, I am investing considerable effort in building a major large-scale multi-year dataset on European shags that will allow me to quantify environmental and quantitative genetic (co)variation across migration, dispersal, survival and reproduction, and thereby identify eco-evolutionary causes and consequences of the variable occurrence of seasonal migration. Current funding: UK Natural Environment Research Council.

3) Ecological and genetic constraints on population demography and viability, and application to conservation strategy: One ultimate objective of theoretical and empirical developments in fundamental population ecology is to provide a rigorous science base with which to inform population management policy: but such science-policy translation is still relatively rarely enacted. I am quantifying temporal and spatial environmental and genetic variation in life-history in a protected population of red-billed choughs, and working with conservation practitioners to achieve science-policy translation. We can thereby provide a case study that highlights opportunities and constraints on application of rigorous population science to conservation policy. Current funding: Scottish Natural Heritage and UK Natural Environment Research Council.

Current Research

I'm currently working on three major research projects, addressing diverse novel questions in population, evolutionary and conservation ecology. For full details of publications see 'Further Info'.

Project 1: Evolutionary ecology of polyandry, inbreeding and fitness.

Understanding the causes and consequences of variation in reproductive strategies among population members is key to understanding mating system evolution and population dynamic outcomes. Yet key selective forces that could drive the evolution of reproductive strategies and resulting mating systems, and key quantitative genetic parameters that could shape evolutionary responses, have still not been elucidated theoretically or quantified empirically. Consequently, I am using a long-term study of a wild population of song sparrows on Mandarte Island, British Columbia, Canada, alongside individual-based simulation modelling, to identify the causes and consequences of polyandry (and resulting extra-pair reproduction) and inbreeding as individual reproductive strategies.

Recent key papers: Wolak, Reid et al. (2018) Evolution, in press; Reid & Wolak (2018) Evolution Letters, online.

 

A song sparrow and Mandarte in all its glory...

The detailed long-term study of the song sparrow population means that complete pedigree (family tree) data exist for all sparrows alive on Mandarte back to 1975, based on the observed social mating system. Using these data, I quantified physiological and life-history causes and consequences of inbreeding. I showed that measures of immune reponse decrease dramatically with increasing inbreeding, as does male song repertoire size (a secondary sexual trait, Reid et al. Proc. R. Soc. B 2003, 2005, 2007). I showed that parent and offspring inbreeding coefficients are correlated, and therefore that females expressing directional mating preferences for males with larger song repertoires would on average produce relatively outbred offspring, providing an unexpected benefit of mate choice (Reid et al. Am. Nat. 2006; Proc. R. Soc. B 2007).

However, despite their social monogamy, song sparrows are genetically polygynandrous with frequent extra-pair reproduction. My PhD student Rebecca Sardell genotyped all sparrows on Mandarte since 1993, and assigned all offspring to their true genetic parents. This analyses revealed that 28% of offspring were sired by a male other than their mother's social mate (Sardell et al. Mol. Ecol. 2010). Now we have a shiny new pedigree that incorporates 28% of paternal links corrected for extrapair paternity. Thanks to hard work by Pirmin Nietlisbach (Nietlisbach et al. Proc. R. Soc. B 2017), the corrected pedigree is now complete up to 2016, and really is nearly perfect...

The comprehensive pedigree data allow us to answer many fascinating questions regarding the magnitudes of inbreeding depression and additive genetic variance in sex-specific fitness, and the quantitative genetic basis and consequences of extra-pair reproduction and inbreeding.

Contrary to expectation, Rebecca found that extra-pair offspring tend to be less fit than their within-pair half-sibs.  More specifically, a polyandrous female's daughters that were sired by extra-pair males tend to be less fit than daughters that were sired by the females social mate, while the opposite is true for sons (Sardell et al. Proc. R. Soc. B 2011; Am. Nat. 2012). My postdoc Christophe Lebigre tested the hypothesis that extra-pair reproduction increases the variance in male fitness.  Again contrary to widespread prediction, the increase in variance was relatively small (Lebigre et al. Evolution 2012).

Bringing in an explicit quantitative genetic angle, I showed that the proportion of a female's offspring that is sired by an extra-pair male is heritable, while a male's extra-pair reproductive success shows substantial inbreeding depression (Reid et al. Proc. R. Soc. B 2011; Am. Nat. 2011).  Furthermore, and again opposite to expectation, I showed that polyandrous females have offspring of lower additive genetic value for survival by mating with an extra-pair male than by mating with their socially paired mate (Reid & Sardell Proc. R. Soc. B 2012). Recent quantitative genetic analyses showed that there are also male genetic effects on the probability of extra-pair paternity (Reid et al. Evolution 2014). However, there is no detectable cross-sex genetic correlation between female extra-pair reproduction and male reproductive fitness, negating the hypothesis that female multiple mating could be driven by cross-sex indirect selection (Reid & Wolak Evol. Let. 2018).

Alongside this work on extra-pair reproduction, I focussed again on the evolutionary ecology of inbreeding. Matthew Wolak used a heroic quantitative genetic analysis to show the the degree to which song sparrows pair with relatives is heritable (Wolak & Reid Am. Nat. 2016), but the sparrows do not substantially use extra-pair reproduction to avoid inbreeding (Reid et al. Evolution 2014). To rationalise this result, I integrated information on relatedness and reproductive success to show that the occurrence of strong inbreeding depression does not necessarily lead to selection against inbreeding (Reid et al. Evolution 2015). I then drew together the worlds of inbreeding and extra-pair reproduction, and calculated the degree to which parents are actually related to the brood of offspring that they rear. These analyses revealed substantial variation in relatedness among nuclear families, partly because males are commonly related to extra-pair offspring that they didn't sire but could rear (Reid et al. Evolution 2016).

Meanwhile, my postdocs Brad Duthie and Greta Bocedi used genetically explicit individual-based models to identify processes that can drive or constrain the evolutionary dynamics of inbreeding and polyandry. In a nutshell, these models show that, in systems with biparental reproduction, the conditions that drive evolution of inbreeding avoidance (or preference) are likely to be more restricted than is commonly assumed (Duthie et al. Evolution 2016; Am. Nat. 2016). However, sperm competition that results from polyandry might drive feedback loops that further increase polyandry (Bocedi & Reid Am. Nat. 2016), especially when there is inbreeding and hence inbreeding depression in male gametic traits (Bocedi & Reid Evolution 2017). Brad also combined mathematical models of kin selection and inbreeding to show that the optimal degree of parental investment in offspring increases with inbreeding (Duthie, Lee & Reid Proc. R. Soc. B 2016) and there is tantalising evidence that the predicted relationships are bourne out by patterns of parental care in the song sparrows...

More recently, Matthew Wolak and I used cutting-edge 'animal model genetic group' methods (Wolak & Reid J. Anim. Ecol. 2017) to quantify additive genetic variance in fitness in the song sparrows, while explicitly estimating additive genetic effects of immigrants. These new analyses reveal that there is non-zero additive genetic variance in fitness in both sexes with a positive cross-sex genetic correlation, but that natural immigrants have low mean additive genetic value for fitness (Wolak et al. Evolution 2018). Future analyses will focus on the role of immigrants in shaping local genetic and phenotypic variation, including involving inbreeding and extra-pair reproduction...

Project 2: Eco-evolutionary dynamics in spatially-structured seasonally-varying environments.

Despite burgeoning interest in understanding eco-evolutionary responses to environmental change, there is still substantial theoretical and empirical failure to consider population responses driven by variable expression of a critical trait that directly links population and evolutionary dynamics in seasonally-varying environments: reversible seasonal migration.

Seasonal migration is a critical trait that can allow individuals to increase their reproductive success and/or survival by exploiting seasonal resource peaks while avoiding seasonal ecological and environmental risks. It is increasingly clear that the expression of seasonal migration (versus year-round residence) is a highly variable individual trait in many systems, generating diverse forms of 'partial migration'. Yet the degree to which the expression of seasonal migration could show rapid plastic and/or micro-evolutionary responses to environmental variation and change, and hence drive profound population dynamic responses and forms of 'evolutionary rescue' that radically change seasonal population distributions, has scarcely been considered, either theoretically or empirically.

Accordingly, my current aims are to provide new theoretical and empirical understanding of how eco-evolutionary dynamics arising in spatially-structured seasonally-mobile populations can drive population dynamics and persistence in the face of seasonal environmental change.

Recent key prospective review paper: Reid et al. (2018) Biological Reviews, online.

Schematic overview of the central role of the variable expression of seasonal migration in shaping eco-evolutionary outcomes:

 

Individual variation in the expression of reversible seasonal migration versus year-round residence both directly links seasonal environmental variation and change with spatio-temporal (circannual) population dynamics, and could affect reproduction, survival and dispersal and thereby drive major eco-evolutionary feedbacks. Yet, the potential for evolving seasonal migration to drive rapid and radical forms of 'evolutionary rescue' has not been considered theoretically, and key forms of plasticity, selection, gene flow and assortative mating and genetic variation involving seasonal migration have not been quantified empirically in any systems.

Progress towards achieving these empirical ambitions requires multi-year, large-scale, field studies that quantify seasonal migration versus residence, and associated reproduction, survival, dispersal and assortative mating in huge numbers of individuals across multiple locations, years and generations: but this has not previously been achieved. Accordingly, since 2009, I have invested huge effort in collecting the required data in a partially-migratory meta-population of European shags, in close collaboration with Francis Daunt's research group (UK Centre for Ecology & Hydrology).

With the huge help and enthusiasm of numerous bird ringing groups and volunteer observers, since 2009, we have ringed ~17,800 shags at colonies along the east coasts of Scotland and northern England. We have amassed ~54,000 winter resightings and ~9,700 breeding recorded of ringed individuals, and are compiling extensive pedigree data for quantitative genetic analyses. With just a couple more years of fieldwork (honest!), these data should allow us to quantify key components of demographic, environmental and quantitative genetic (co)variation spanning seasonal migration, reproduction, survival, dispersal and mating in females and males of all ages.

Colour-ringing and field resighting might seem like 'old technology' in these days of amazing tracking devices, but as yet it still provides the best route to rigorous evolutionary demography and quantitative genetics. We can mark huge numbers of individuals soon after hatch, and then non-invasively collect substantial life-long data on reproductive success, survival, dispersal and mating. Shags provide an excellent model system for such work because they breed in known, observable, colonies and are restricted to coastal environments, meaning that individuals can be readily observed all year round.

Our initial analyses of small data subsets (from 2009-2012) prove that there is huge among-individual variation in winter location; some individuals remain resident at their breeding colony all year round while other individuals migrate several hundred kilometres along the Scottish coast, providing a fascinating example of 'partial migration' (Grist et al. PLoS One 2014). Furthermore, resident shags breeding on the Isle of May had higher breeding success than migrants in these years, indicating that seasonal migration is not neutral (Grist et al. J. Anim. Ecol. 2017 - joournal's 'In Focus' featured paper).

Our new NERC grant will allow us to quantify demographic variation in the occurrence of seasonal migration and start to build some new population dynamic theory for partially-migratory populations - watch this space for the first big results!

Resighting efforts for winter 2018-2019 are now underway - any observations from anywhere along the east coast will be hugely appreciated, please get in touch for further information!

Project 3: Ecological and genetic constraints on population demography and viability, and application to conservation strategy.

One ultimate objective of theoretical and empirical developments in fundamental population ecology is to provide a rigorous science base with which to inform population management policy: but such science-policy translation is still relatively rarely enacted. I am quantifying temporal and spatial environmental and genetic variation in life-history in a protected population of red-billed choughs, and working with conservation practitioners to achieve science-policy translation. We can thereby provide a case study that highlights opportunities and constraints on application of rigorous population science to conservation strategy.

Recent key papers: Trask, Reid et al. (2016) J. Anim. Ecol.; Trask, Reid et al. (2017) J. Anim. Ecol.

Red-billed choughs are of high conservation concern in Scotland and Europe more widely. Since 1980, the Scottish Chough Study Group (led by Eric & Sue Bignal and Davy McCracken) has monitored the breeding success and survival of individually colour-ringed choughs on the Scottish island of Islay, generating a really fantastic long-term demographic dataset. We're using these data to quantify temporal and spatial variation in individual life-histories, identify environmental causes of demographic variation and understand the spatial and temporal dynamics of this population. We are also now incorporating genetic effects, and specifically inbreeding and genetic drift, into population models. We are working with Scottish Natural Heritage and other stakeholders to apply this rigorous population ecology to conservation strategy for choughs in Scotland.

 

Choughs being ringed and observed on Islay.

My PhD student Amanda Trask (funded by NERC and Scottish Natural Heritage) recently used a combination of demographic and molecular genetic data to show that the occurrence of blindness in chough nestlings probably represents the phenotypic expression of a single-locus lethal recessive allele, manifested under inbreeding. Moreover this allele is likely to be relatively widespread in the population, and possibly maintained by overdominance (Trask et al. J. Anim. Ecol. 2016, featured 'In Focus' paper, and highly commended for the Elton Prize). Amanda subsequently used state-of-the-art demographic analyses to estimate the effective size of Islay's chough population, and found that it is critically small... (Trask et al. J. Anim. Ecol. 2017).

My Honours student Marius Wenzel genotyped choughs from several European populations to establish the degree of genetic differentiation among populations. His results show strong genetic structuring across the species' current range, and show that the choughs that recently recolonised Cornwall most probably originated in Ireland (Wenzel et al. Cons. Gen. 2012)! Marius won the Charles Darwin Award (from the Zoological Society of London) for the best Zoology Honours thesis in the UK - well done Marius!

Meanwhile, a collapse in first-year survival rates prompted the introduction of a programme of emergency supplementary feeding on Islay. My new PhD student Sarah Fenn (also funded by NERC and SNH) is working out how effective this programme has been...

Sub-adult choughs and their emergency mealworms...

Amanda is now working on a population viability analysis that combines ecological and genetic effects, with the aim of informing Scottish Natural Heritage on the possible effects of continued supplementary feeding and/or potential translocations to alleviate inbreeding. Policy decisions to be taken shortly!
