I am interested in using contemporary molecular tools to address diverse questions focusing on biodiversity, ecology and evolution. This is a particularly exciting time in the field of molecular ecology, since advances in DNA sequencing throughput have recently offered a paradigm shift in our ability to assess previously intractable functional and taxonomic biodiversity at an unprecedented scale, augmenting existing biodiversity fields and empowering others. Using such technologies, I am testing a range of hypotheses regarding the alpha and beta functional and taxonomic diversity of macro-, meio- and microbial communities (e.g. microbiomes) in space and time, based on genomic, community and environmental DNA (eDNA). Focal habitats have included estuarine, coastal and deep sea environments with an increasing focus now on freshwater, terrestrial, whole organisms and the aerial biosphere in order to understand the drivers of diversity in natural communities and also how diversity is linked with ecological function, trophic relationships, environmental and human health. Current additional activities include phylogenomics, population genetics, life history evolution, polyploidy, pollination genomics.

NERC PollerGEN - Understanding links between grass pollen and human health in the UK
For millions of people, the onset of spring and summer brings misery as they battle with itchy eyes and sneezing brought about by their reaction to pollen. Up to 25% of the UK population are sensitised to grass pollen and around 10% suffer asthma that can be aggravated by pollen. However, with around 150 different species of grass in the UK and no easy way of distinguishing between different pollen grains, identifying which species of grass pollen people are allergic to is a challenge.
In PollerGEN, a £1.2M NERC investment, we aim to develop a species level, spatio-temporal pollen assessment framework throughout the UK and develop novel pollen bio-aerosol models in order to identify which species are linked to the exacerbation of asthma.
The PollerGEN team comprises researchers from Bangor, Aberystwyth, Worcester and Exeter Universities, in collaboration with the UK Met office, supported by a range of stakeholder groups and charities. We will use a range of molecular genetic solutions, from shotgun environmental sequencing through to quantitative PCR to quantify the pollen landscape, followed by leading-edge aerobiological modelling and identifying links to the aggravation of asthma throughout the grass pollen season.
Understanding which species of grass pollens are in the air in high quantities at a particular time will allow those with hay fever and asthma to better manage their disease by being aware of risky periods, avoiding exposure and having their medicines to hand. It is predicted that the new forecasts will give more precise (and shorter) time periods that disease sufferers will have to be cautious in, and provide guidance of when these may occur.
Enhancing freshwater ecosystem biomonitoring: defining and testing an ecometagenetic DNA identification framework.
Biological indicators are used to estimate the state of the environment and the Environment Agency mandatorily monitors the health of freshwater ecosystems throughout the UK. However, traditional monitoring approaches suffer from the “identification bottleneck” problem (e.g. subjectivity, lack of resolution, labour-intensive traditional taxonomy approaches mismatched with ecosystem diversity). This KESS-funded PhD program, in collaboration with Iliana Bista and the Environment Agency, will populate a DNA reference library for up to 200 macroinvertebrate indicator species and test and test the efficacy of the use of second generation sequencing approaches in enhancing freshwater biomonitoring programs.

Understanding the microbial mechanisms underpinning carbon release from peatland ecosystems.
In their natural waterlogged state, peatlands constitute the most important, long-term, terrestrial organic carbon store on our planet. However, it has been shown that under drought conditions the stored carbon is released as atmospheric gaseous CO2 and dissolved organic carbon (DOC) into surrounding waterways, contributing to global warming and the net loss of carbon from peatland ecosystems. Here, funded by the HPC Wales/Fujitsu partnership and partnered with Welsh Water, we will use "metagenetic" and shotgun "metagenomic" approaches to identify both the composition and functional diversity of the microbial communities responsible for drought-driven carbon loss from a range of peatland ecosystems. By understanding the mechanisms associated with carbon loss, we will be able to explore approaches aimed at regulation of key microbial drivers of carbon loss through the geo-engineering of peatlands to regain carbon. Such a multidisciplinary project demands expertise in wetland biogeochemistry and metagenomics and is lead by Caitlin Potter, in collaboration with Prof. Chris Freeman, Prof. Peter Golyshin, Dr. Nathalie Fenner and Dr. James McDonald.
Glastir Monitoring and Evaluation Programme (GMEP): Soil biodiversity
Intensively monitoring ecosystems in relation to land management schemes and monitoring progress towards a range of international biodiversity and environmental targets is a crucial aspect of understanding landscape interventions and the effects of environmental change. As part of the wider Glastir Monitoring and Evaluation Programme (GMEP), this project will investigate alpha and beta diversity of soil prokaryote, fungal and microbial eukaryotes and a range of abiotic soil factors across the Welsh landscape. Our aim is to better understand linkages and drivers of biodiversity between the abiotic and biotic realms and potential linkages between below-ground and above ground processes in relation to management regimes employed across a variety of ecological habitats.
The macroecology of marine benthic meiofaunal diversity
Marine benthic biodiversity is important for ecosystem functioning, sustainability and resilience, but the magnitude and composition of marine diversity at a range of spatial and taxonomic scales are undefined. Marine meiofaunal communities are dominated by the potentially hyperdiverse nematodes, accompanied by other small metazoans from 60% of animal phyla, therefore presenting a major fraction of global biodiversity. Despite the abundance and pivotal role in ecosystem functioning, a current estimate of global meiobenthic diversity remains a matter of conjecture. This knowledge gap is the result of the small size and the apparent morphological similarity of microbial metazoans that causes problems in the logistics and accuracy of species identification. Over the past few years myself and collaborators have contributed substantially to the development of a new field of eukaryotic biodiversity identification, that uses "second", or "next" generation sequencing approaches to simultaneously assess the richness of multiple phyla from the marine benthos. Empirical and perspective style papers have been published in Molecular Ecology, Nature Communications, Nucleic Acids Research and Trends in Ecology and Evolution.
Are marine nematodes hyperdiverse?
This NERC funded project used standard and novel molecular approaches (454 Roche 18S sequencing) and videocapture technology to estimate the actual molecular (and subsequent species) diversity present at different spatial scales throughout littoral communities of UK nematodes and other meiofauna and extrapolate this information to estimates of regional and global species richness. The utilization of second-generation sequencing to quantify molecular biodiversity represents a major advance towards identifying a crucial biological component of the earth's ecosystems and enable further hypotheses to be tested regarding the complex nature of 454 sequencing.
Sequencing the meiofaunal metagenome of the fresh/saltwater interface.
Estuaries are key transitional habitats that are significantly affected by local and global anthropogenic activities. They are typically considered to be low diversity systems; a taxonomically biased inference drawn from the low alpha diversity of macrofauna. In contrast, meiofaunal diversity is substantial, with most estuaries estimated to be inhabited by approximately 200 species of nematodes, with numbers ranging from 106-108 animals per square metre, contributing to between 50-90% of the metazoan faunal species richness. In collaboration with The Environment Agency, The Thames Estuary Partnership and The Mersey Basin Campaign, this NERC funded project will link large-scale biodiversity appraisals (454 18S sequencing, videocapture and morphology) of environmental samples across ecological gradients with hydrodynamic models and macrofaunal processes.
Understanding the functional genomic mechanisms underpinning endocrine disruption in the ecological sentinel, Nucella lapillus
Man-made chemicals that disrupt endocrine function (endocrine dispuptors) contaminate all environments, producing a range of undesirable effects across a wide range of taxa and can cause abnormal development of male and female traits. The female dogwhelk, Nucella lapillus, provides one of the most clearcut examples of anthropogenically induced endocrine disruption in aquatic ecosystems and is used as an “ecological sentinel” to detect the detrimental effect of tributyltin (TBT) in marine ecosystems. Combining second-generation transcriptome sequencing and Agilent 180K feature microarray fabrication, this work aimed to unravel the functional genomic mechanisms underpinning the action of TBT in the imposex response (the superimposition of male sexual characteristics in females) in Nucella. We were able to simultaneously observe the involvement of previously identified pathways, but also discover and confirm the involvement of additional putative PPAR pathways, providing evidence for novel commonality in endocrine disruption signalling pathways between invertebrates and vertebrates. Arising from the PhD program of Dr. Sonia Pascoal and funded by FCT and the NERC NBAF program, this work, published in Molecular Ecology was a great collaboration between MEFGL members, Prof. Andy Cossins and colleagues from the Liverpool Centre for Genomic Research and Carlos Barroso and Sonia Mendo (University of Aveiro, Portugual).
