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 academic career in ecology is balanced by my experience and enthusiasm as a field naturalist; I have worked at bird observatories and on numerous field projects in the UK and elsewhere.  I'm committed to using a combination of fieldwork, rigorous analyses of long-term data and modelling to gain an integrated understanding of the structure, and population and evolutionary dynamics, of natural populations. I actively translate my research into public understanding and population management policy.


Research Interests

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 this life-history 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 investigate these issues by integrating approaches and questions drawn from population ecology, evolutionary ecology and behavioural ecology. I use field experiments and long-term data from individual-based studies of wild bird populations, coupled with sophisticated statistical analyses and simulation modelling.

Current projects focus on:

1) Evolutionary ecology of extra-pair reproduction and inbreeding, using an amazing long-term dataset on song sparrows coupled with quantitative genetic and simulation modelling.

2) Links between environmental and genetic variation and temporal and spatial variation in life-history in red-billed choughs, and application to conservation policy.

3) Population and evolutionary dynamics of partial migration, by quantifying covariation across migration, dispersal, survival and reproduction in partially-migratory European shags.

4) Long-term changes in migration timing and the composition of migratory bird assemblages, using another amazing long-term dataset from Fair Isle Bird Observatory.

Current Research

I'm currently working on four main research projects. For details of publications see the 'Further Info' tab.

Project 1: Evolutionary ecology of extra-pair reproduction and inbreeding in song sparrows, collaborating with Peter Arcese (University of British Columbia) & Lukas Keller (Universität Zürich).

Understanding the nature, causes and consequences of reproductive strategies among population members is key to understanding fundamental evolutionary and ecological processes that shape natural populations. I'm using a long-term study of a wild population of song sparrows on Mandarte Island, British Columbia, Canada, alongside individual-based simulation modelling, to investigate the causes and consequences of polyandry (extra-pair reproduction) and inbreeding as individual reproductive strategies.


A song sparrow and Mandarte

The detailed long-term study of this 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 investigated the 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 Pirmin Nietlisbach, the corrected pedigree is now complete up to 2015, and really is nearly perfect...

The comprehensive pedigree data allow us to answer many fascinating questions regarding the magnitude of inbreeding depression and variance in fitness, and the quantitative genetic basis and consequences of polyandry, 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).

I used quantitative genetic 'animal model' analyses to show 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).

More recently, I have been focussing 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). 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, not least 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 have used genetically explicit individual-based models to explore 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.


Project 2: Environmental and genetic effects on demography and population dynamics, applied to conservation policy for red-billed choughs, in collaboration with Prof P. Monaghan (University of Glasgow), Eric Bignal & Sue Bignal (Scottish Chough Study Group) & Davy McCracken (Scotland's Rural College).

Since 1980, the Scottish Chough Study Group 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 considerations, and specifically inbreeding (surprise!) 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, and featured in Journal of Animal Ecology

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!

My PhD student Amanda Trask (funded by NERC and Scottish Natural Heritage) followed up on the genetic theme, and used a combination of demographic and molecular genetic data to show that the occurrence of blindness in chough nestlings most 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 as the journal's 'In Focus' paper).

Amanda has now used state-of-the-art demographic analyses to estimate the effective size of Islay's chough population, and found that it is critically small...


Project 3: Demographic and population dynamic consequences of partial migration in shags, collaborating with Francis Daunt & Sarah Wanless (Centre for Ecology & Hydrology)

A key aim in population ecology is to understand how life-history variation, and hence population demography and dynamics, arises as a consequence of the environmental conditions that individuals experience both currently and previously. Many wild animals migrate among different locations between seasons, and it is widely hypothesised that environments experienced in one season or location might affect an individual's reproduction or survival in subsequent seasons or locations. Yet few field studies have been able to track large numbers of individual population members across different seasonal locations, thereby allowing individual variation in reproductive success to be related to individual variation in winter location.

A breeding colony of shags on the Isle of May, Firth of Forth, has been studied in detail since 1998 by CEH. Almost all adults are individually marked with field-readable rings, and their breeding success and survival are documented. We have recently discovered that it is possible to locate a substantial proportion of these individuals in winter, and that there is remarkable variation in winter location; some individuals remain on the Isle of May while others move several hundred kilometres around the Scottish coast. This has sparked more intensive winter fieldwork, and an excuse to spend my weekends wandering along random bits of Scottish coastline.  Fraserburgh is definitely my favourite place!

With the huge help and enthusiasm of numerous bird ringing groups and volunteer observers, since 2009, we have now ringed ~13,500 shags everywhere from the Farne islands (in north-east England) to Shetland. We have amassed ~42,000 winter resightings of these individuals along the UK east coast. With just a couple more years of data (honest!), these data should allow us to quantify all key components of demographic (co)variation spanning females and males of all ages.


Project 4: Long-term dynamics of migration timing, collaborating with Fair Isle Bird Observatory Trust.

Fair Isle, and its bird observatory, has long been one of my favourite places - if you haven't visited yet you really should!

Fair Isle Bird Observatory has been recording species and numbers of migrant birds for decades. We have recently had all the data digitised, and the first analyses of the long-term data are already revealing some unexpected and fascinating changes in migration timing over the last 60 years.
