Oxylipin signalling in a coral-dinoflagellate symbiosis Open
The symbiotic relationship of cnidarians with dinoflagellates of the family Symbiodiniaceae is based on host-symbiont recognition processes and continuous molecular exchange between partners. However, the molecular signals involved are unr…

Stability of the cnidarian–dinoflagellate symbiosis is primarily determined by symbiont cell-cycle arrest Open
The cnidarian–dinoflagellate symbiosis relies on the regulation of resident symbiont populations to maintain biomass stability; however, the relative importance of host regulatory mechanisms [cell-cycle arrest (CC), apoptosis (AP), autopha…

A novel menthol-DCMU bleaching method for foraminifera: generating aposymbiotic hosts for symbiosis research Open
Understanding the cellular symbiosis between marine holobionts and their endosymbiotic algae is crucial for predicting the resilience of coral reefs to climate change. While bleaching protocols have been widely applied to model organisms s…

The Influence of Symbiont Identity on the Proteomic and Metabolomic Responses of the Model Cnidarian Aiptasia to Thermal Stress Open
We examined the effects of symbiont identity and heat stress on the host metabolome and proteome in the cnidarian–dinoflagellate symbiosis. Exaiptasia diaphana (‘Aiptasia’) was inoculated with its homologous (i.e., native) symbiont Breviol…

Octadecanoids as emerging lipid mediators in cnidarian-dinoflagellate symbiosis Open
Oxylipin signaling has been suggested as a potential mechanism for the inter-partner recognition and homeostasis regulation of cnidarian-dinoflagellate symbiosis, which maintains the ecological viability of coral reefs. Here we assessed th…

A novel menthol-DCMU bleaching method for foraminifera: Generating aposymbiotic hosts for symbiosis research Open
Predicting the response and resilience of coral reefs to climate change can only be achieved through better understanding the cellular symbiosis between coral reef holobionts and their associated endosymbiotic algae. Larger benthic foramin…

COVID-19 and Mental Illnesses in Vaccinated and Unvaccinated People Open
Importance Associations have been found between COVID-19 and subsequent mental illness in both hospital- and population-based studies. However, evidence regarding which mental illnesses are associated with COVID-19 by vaccination status in…

<span>OpenSAFELY</span>: A platform for analysing electronic health records designed for reproducible research Open
Electronic health records (EHRs) and other administrative health data are increasingly used in research to generate evidence on the effectiveness, safety, and utilisation of medical products and services, and to inform public health guidan…
Combined effects of thermal stress and symbiont identity on carbon flux in a model cnidarian-dinoflagellate symbiosis Open
Reef corals rely on their symbiotic relationship with dinoflagellates of the family Symbiodiniaceae for their metabolic energy demands, but this relationship is sensitive to thermal stress which can induce bleaching. We investigated the fl…
Nutrient depletion and heat stress impair the assimilation of nitrogen compounds in a scleractinian coral Open
Concentrations of dissolved nitrogen in seawater can affect the resilience of the cnidarian–dinoflagellate symbiosis to climate change-induced bleaching. However, it is not yet known how the assimilation and translocation of the various ni…

Triggers, cascades, and endpoints: connecting the dots of coral bleaching mechanisms Open
The intracellular coral–dinoflagellate symbiosis is the engine that underpins the success of coral reefs, one of the most diverse ecosystems on the planet. However, the breakdown of the symbiosis and the loss of the microalgal symbiont (i.…

Proteomes of native and non-native symbionts reveal responses underpinning host-symbiont specificity in the cnidarian–dinoflagellate symbiosis Open
Cellular mechanisms responsible for the regulation of nutrient exchange, immune responses, and symbiont population growth in the cnidarian–dinoflagellate symbiosis are poorly resolved, particularly with respect to the dinoflagellate symbio…

Symbiont Identity Impacts the Microbiome and Volatilome of a Model Cnidarian-Dinoflagellate Symbiosis Open
The symbiosis between cnidarians and dinoflagellates underpins the success of reef-building corals in otherwise nutrient-poor habitats. Alterations to symbiotic state can perturb metabolic homeostasis and thus alter the release of biogenic…
Marine heatwave conditions drive carryover effects in a temperate sponge microbiome and developmental performance Open
Marine heatwaves are increasingly subjecting organisms to unprecedented stressful conditions, but the biological consequences of these events are still poorly understood. Here we experimentally tested the presence of carryover effects of h…

Building consensus around the assessment and interpretation of Symbiodiniaceae diversity Open
Within microeukaryotes, genetic variation and functional variation sometimes accumulate more quickly than morphological differences. To understand the evolutionary history and ecology of such lineages, it is key to examine diversity at mul…

The role of irradiance in controlling coralline algal calcification Open
Coralline algae are an essential element of benthic ecosystems throughout the ocean's photic zone. Yet, the role of light in shaping the physiology of coralline algae from cold‐water, low‐light habitats is poorly understood. Here, we asses…
Genomic conservation and putative downstream functionality of the phosphatidylinositol signalling pathway in the cnidarian-dinoflagellate symbiosis Open
The mutualistic cnidarian–dinoflagellate symbiosis underpins the evolutionary success of stony corals and the persistence of coral reefs. However, a molecular understanding of the signalling events that lead to the successful establishment…

Tolerance of coralline algae to ocean warming and marine heatwaves Open
Ocean warming (OW) and marine heatwaves (MHWs) rapidly transform marine ecosystems, especially when they impact keystone or foundation species. Foundation species such as kelps, fucoids and corals are highly sensitive to heat stress, which…
The<i>Symbiodinium</i>Proteome Response to Thermal and Nutrient Stresses Open
