Cryptic reef communities and global change<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Coral reefs are among the most biologically diverse, complex, and economically valuable ecosystems on earth; tentatively valued at $1 trillion USD annually. These systems are also in global decline and with their loss, we are also losing the goods and services reefs provide. While efforts are being made to establish conservation priorities for halting their decline, we are still fundamentally limited by our inadequate knowledge of what is being lost because the baseline of what of exists on coral reefs is incomplete. We use a range of standardised techniques (e.g. Autonomous Reef Monitoring Structures), alongside metagenomics and metabolomics, to answer questions, such as: what are the functional roles of the hidden members of coral reef communities<\/em>, what is the impact of global change on reef biodiversity<\/em> and can we use microbes as early warning systems to determine ecosystem collapse on coral reefs<\/em>? To this end, we have set up a project called FUTURE REEF<\/a><\/strong> to collate global sequencing and environmental data to better understand coral reef biodiversity in a changing world. This work has been funded through four PhD studentships in collaboration with the Smithsonian National Museum of Natural History, the Institute of Zoology, Oxford University, and NatureMetrics. Current funding comes from our \u00a310M Leverhulme Centre for the Holobiont<\/a> <\/strong>at Imperial College London and a NERC Large Grant<\/strong><\/a> on mesophotic coral reefs.

Viral ecology<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Our interest in aquatic microbial communities extends to the little understood but extraordinarily abundant viral component of these ecosystems. Viruses have been mostly ignored in community ecology and ecosystem modelling because their ecology has remained enigmatic until the recent advent of new molecular approaches. For example, viruses that \u201cprey\u201d on bacteria (bacteriophage) are responsible for 10-50% of bacterial mortality in marine systems, altering bacterial community structure and redirecting nutrients and energy away from the higher trophic levels and back into the microbial food web. However, despite the growing recognition that viruses play key roles in shaping ecosystems, the impact environmental change has on viral interactions with other organisms remains poorly understood. This unexplored area in ecology is arguably one of our biggest blind-spots in advancing a truly holistic approach to ecosystem biology. As such, this is a growing area of research in our lab. <\/p>\n\n\n\n

We have used our expertise in this area to understand the potential transmission of SARS-CoV-2 in the environment via sewage, wildlife, and air pollution. This work has involved setting up a CL3 facility to study SARS-CoV-2 as infectious particles and testing novel technologies to monitor pathogens in the environment. This work has been funded through an Innovate UK grant, and a collaboration with the Accelerated Capability Environment (ACE), a Home Office capability within the Homeland Security Group. We are now working to understand the viral role in deterring a major fungal disease of wheat plants through a Uren Foundation<\/a><\/strong> grant called the Microbiome Green Revolution Project<\/strong><\/a>, that has the aim of sustainably increasing crop yields.

Microbial interactions in a changing world<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Aquatic environments are facing a multitude of stressors, and it is becoming increasingly apparent that stressor impacts may be strongly interdependent on each other. However, we currently know little about the impact of multiple stressors on complex communities in freshwater and marine systems, or about the importance of community structure and environmental history in resisting environmental stress. The traditional focus on single stressors, and single key stone species (e.g. fish), unsurprisingly misses key information on the interactive effects of stressors and species. The Ransome lab works across scales (laboratory experiments, to large-scale mesocosm experiments (e.g. the Silwood Mesocosm Facility<\/strong><\/a>)) to understand the interactions between multiple stressors and microbial communities. This work has been funded through a NERC grant<\/strong><\/a> (PI Woodward), in collaboration with multiple collaborators at Imperial and elsewhere (Bell, Pawar, Dumbrell, Jackson).

Seagrass restoration<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

In a new area of research for the Ransome lab, we are working with Ocean Conservation Trust (OCT)<\/strong><\/a> and the Blue Meadows Project to understand the how and where to restore seagrass most efficiently. This work involves understanding the interactions between microbial communities and environmental factors in contributing to seagrass health, and understanding the variability in long-term carbon storage in seagrass sediments. We are particularly interested in the role of microbial probiotics in creating productive seagrass nurseries for restoration. This work has been funded through the Blue Meadows Project, an Imperial-OCT FSRF grant, and SSCP DTP <\/strong><\/a>and Imperial DoLS<\/strong><\/a> studentships.
