Rising water temperature in rivers: Ecological impacts and future resilience (2024)
Journal Article

Rising water temperatures in rivers due to climate change are already having observable impacts on river ecosystems. Warming water has both direct and indirect impacts on aquatic life, and further aggravates pervasive issues such as eutrophication, p...

Reproductive isolation in a three‐way contact zone (2024)
Journal Article

Contact zones between divergent forms within a species provide insight into the role of gene flow in adaptation and speciation. Previous work has focused on contact zones involving only two divergent forms, but in nature, many more than two populatio... Read More about Reproductive isolation in a three‐way contact zone.

On the origins of phenotypic parallelism in benthic and limnetic stickleback (2023)
Journal Article

Rapid evolution of similar phenotypes in similar environments, giving rise to in situ parallel adaptation, is an important hallmark of ecological speciation. However, what appears to be in situ adaptation can also arise by dispersal of divergent line... Read More about On the origins of phenotypic parallelism in benthic and limnetic stickleback.

A Common Anaesthetic, MS-222, Alters Measurements Made Using High-Resolution Respirometry in the Three-Spined Stickleback (Gasterosteus aculeatus) (2023)
Journal Article

Submersion in the anaesthetic MS-222 is a well-established and effective method used during the euthanasia of fish, but the consequences of treatment with this anaesthetic for mitochondrial respiration are yet to be established. This is important to... Read More about A Common Anaesthetic, MS-222, Alters Measurements Made Using High-Resolution Respirometry in the Three-Spined Stickleback (Gasterosteus aculeatus).

The maintenance of standing genetic variation: Gene flow vs. selective neutrality in Atlantic stickleback fish (2021)
Journal Article

Adaptation to derived habitats often occurs from standing genetic variation. The maintenance within ancestral populations of genetic variants favourable in derived habitats is commonly ascribed to long-term antagonism between purifying selection and...

Courtship behavior, nesting microhabitat, and assortative mating in sympatric stickleback species pairs (2021)
Journal Article

© 2021 The Authors. Ecology and Evolution published by John Wiley & Sons Ltd. The maintenance of reproductive isolation in the face of gene flow is a particularly contentious topic, but differences in reproductive behavior may provide the key to ex...

Intercontinental genomic parallelism in multiple three-spined stickleback adaptive radiations (2020)
Journal Article

© 2020, The Author(s), under exclusive licence to Springer Nature Limited. Parallelism, the evolution of similar traits in populations diversifying in similar conditions, provides strong evidence of adaptation by natural selection. Many studies of pa...

Geographical location influences the composition of the gut microbiota in wild house mice (Mus musculus domesticus) at a fine spatial scale (2019)
Journal Article

The composition of the mammalian gut microbiota can be influenced by a multitude of environmental variables such as diet and infections. Studies investigating the effect of these variables on gut microbiota composition often sample across multiple se...

Admixture between ancient lineages, selection, and the formation of sympatric stickleback species-pairs (2019)
Journal Article

Ecological speciation has become a popular model for the development and maintenance of reproductive isolation in closely related sympatric pairs of species or ecotypes. An implicit assumption has been that such pairs originate (possibly with gene fl...

Immune state is associated with natural dietary variation in wild mice Mus musculus domesticus (2019)
Journal Article

1. The ability, propensity and need to mount an immune response vary both among individuals and within a single individual over time. 2. A wide array of parameters have been found to influence immune state in carefully controlled experiments, but... Read More about Immune state is associated with natural dietary variation in wild mice Mus musculus domesticus.

Internal embryonic development in a non-copulatory, egg-laying teleost, the three-spined stickleback, Gasterosteus aculeatus (2019)
Journal Article

The switch from egg-laying to retaining and giving birth to live young is a major transition in the history of life. Despite its repeated evolution across the fishes, records of intermediate phenotypes are vanishingly rare, with only two known cases...

Predictable genome-wide sorting of standing genetic variation during parallel adaptation to basic versus acidic environments in stickleback fish (2019)
Journal Article

Genomic studies of parallel (or convergent) evolution often compare multiple populations diverged into two ecologically different habitats to search for loci repeatedly involved in adaptation. Because the shared ancestor of these populations is gener...

DNA fragility in the parallel evolution of pelvic reduction in stickleback fish (2019)
Journal Article

Evolution generates a remarkable breadth of living forms, but many traits evolve repeatedly, by mechanisms that are still poorly understood. A classic example of repeated evolution is the loss of pelvic hindfins in stickleback fish (Gasterosteus acul...

Habitat correlates of Eurasian woodcock Scolopax rusticola abundance in a declining resident population (2018)
Journal Article

In Europe, woodland bird populations have been declining since at least the 1970s, and in Britain, around one third of woodland bird species have undergone declines over this period. Habitat change has been highlighted as a possible cause, but for so... Read More about Habitat correlates of Eurasian woodcock Scolopax rusticola abundance in a declining resident population.

A genetics-based approach confirms immune associations with life history across multiple populations of an aquatic vertebrate (Gasterosteus aculeatus) (2018)
Journal Article

Understanding how wild immune variation covaries with other traits can reveal how costs and trade?offs shape immune evolution in the wild. Divergent life history strategies may increase or alleviate immune costs, helping shape immune variation in a c...

What Are the Environmental Determinants of Phenotypic Selection? A Meta-analysis of Experimental Studies (2017)
Journal Article

Although many selection estimates have been published, the environmental factors that cause selection to vary in space and time have rarely been identified. One way to identify these factors is by experimentally manipulating the environment and measu... Read More about What Are the Environmental Determinants of Phenotypic Selection? A Meta-analysis of Experimental Studies.

Abiotic environmental variation drives virulence evolution in a fish host-parasite geographic mosaic (2017)
Journal Article

1. Parasite virulence varies greatly. Theory predicts that this arises from parasites optimising a trade-off between the mortality they inflict on current hosts, and their transmission to future hosts. The effect of the environment on this coevolutio... Read More about Abiotic environmental variation drives virulence evolution in a fish host-parasite geographic mosaic.

Precipitation drives global variation in natural selection (2017)
Journal Article

Climate change has the potential to affect the ecology and evolution of every species on Earth. While the ecological consequences of climate change are increasingly well documented, the effects of climate on the key evolutionary process driving adapt...

Eda haplotypes in three-spined stickleback are associated with variation in immune gene expression (2017)
Journal Article

Haplotypes underlying local adaptation and speciation are predicted to have numerous phenotypic effects, but few genes involved have been identified, with much work to date concentrating on visible, morphological, phenotypes. The link between genes c... Read More about Eda haplotypes in three-spined stickleback are associated with variation in immune gene expression.
