Humic substances modulate bacterial communities and mitigate adverse effects of temperature stress in coral reef organisms Open
Aims In the present study, we tested whether terrestrially derived humic substances (HS) could mitigate the adverse effects of elevated temperature and ultraviolet B (UVB) radiation on the bacterial communities of two hard corals (Montipor…

Development and validation of an experimental life support system to study coral reef microbial communities Open
In the present study, we developed and validated an experimental life support system (ELSS) designed to investigate coral reef associated bacterial communities. The microcosms in the ELSS consisted of coral reef sediment, synthetic seawate…

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…

Humic substances mitigate adverse effects of elevated temperature with potentially critical repercussions for coral reef resilience Open
Previous observational studies have suggested that terrestrially-derived compounds, most notably humic substances (HS) can protect coral reefs from thermal stress. No study hitherto has, however, tested this hypothesis. In the present stud…

Development and validation of an experimental life support system to study the impact of ultraviolet B radiation and temperature on coral reef microbial communities Open
In the present study, we developed and validated an experimental life support system (ELSS) designed to investigate the response of coral reef associated bacterial communities to increases in temperature and UVB intensity. The ELSS consist…

Cladobranchia (Gastropoda, Nudibranchia) as a Promising Model to Understand the Molecular Evolution of Photosymbiosis in Animals Open
Symbiosis with photoautotrophic organisms has evolved in various species and even whole animal lineages, which allowed them to directly benefit from photosynthesis. This so-called photosymbiosis is best studied in cnidarians, which primari…

Consensus Guidelines for Advancing Coral Holobiont Genome and Specimen Voucher Deposition Open
Coral research is being ushered into the genomic era. To fully capitalize on the potential discoveries from this genomic revolution, the rapidly increasing number of high-quality genomes requires effective pairing with rigorous taxonomic c…

Description of <i>Freudenthalidium</i> gen. nov. and <i>Halluxium</i> gen. nov. to Formally Recognize Clades Fr3 and H as Genera in the Family Symbiodiniaceae (Dinophyceae) Open
The Symbiodiniaceae are a family of marine dinoflagellates known mostly for their endosymbiotic interactions with invertebrates and protists, but facultatively and exclusively free‐living life histories in this family are also evident. A r…

Symbiolite formation: a powerful in vitro model to untangle the role of bacterial communities in the photosynthesis-induced formation of microbialites Open
Microbially induced calcification is an ancient, community-driven mineralisation process that produces different types of microbialites. Symbiolites are photosynthesis-induced microbialites, formed by calcifying co-cultures of dinoflagella…

Protocol for the generation of axenic/bacteria-depleted Symbiodiniaceae cultures v1 Open
This protocol produces bacteria-depleted (“axenic”) Symbiodiniaceae cultures. The depletion level achieved using the following methods is comparable to what was previously described as an “axenic” culture (Bieri et al., 2016; Xiang et al.,…

An LED-based multi-actinic illumination system for the high throughput study of photosynthetic light responses Open
The responses of photosynthetic organisms to light stress are of interest for both fundamental and applied research. Functional traits related to the photoinhibition, the light-induced loss of photosynthetic efficiency, are particularly in…

Symbiodinium-Induced Formation of Microbialites: Mechanistic Insights From in Vitro Experiments and the Prospect of Its Occurrence in Nature Open
Dinoflagellates in the genus Symbiodinium exhibit a variety of life styles, ranging from mutualistic endosymbioses with animal and protist hosts to free-living life styles. In culture, Symbiodinium spp. and naturally associat…

Coral symbiotic algae calcify <i>ex hospite</i> in partnership with bacteria Open
Significance The dinoflagellate genus Symbiodinium is best known for harboring important endosymbiotic algae of marine invertebrates, notably reef-building corals. However, these dinoflagellates also live freely within coral reef waters an…
