“…Unfortunately, cyanobacterial diversity in Okinawa is largely unexplored, and only a few studies on the diversity or epidemiology of marine cyanobacteria have been conducted. For example, diversity studies have shown that marine macroscopic colony-forming filamentous cyanobacteria from Okinawan coasts are genetically very diverse (Suda et al 2013;Nuryadi et al 2020) (Yamashiro et al 2014) and black band disease in coral (Hutabarat et al 2018), respectively.

Okinawan coasts are a rich source of biodiversity, including of filamentous cyanobacteria, owing to their habitat diversity created by coral reefs. Along the coastlines of Okinawa, several undescribed species, including those from Neolyngbya, remain unexplored. In this study, two undescribed cyanobacterial species with morphological resemblance to Neolyngbya were identified using a polyphasic approach. Both taxa had morphological features similar to known species of Neolyngbya; however, the cell size and thallus shape were different. Phylogenetic analyses of the 16S rRNA gene and the 16S-23S rRNA internal transcribed spacer (ITS) region showed that the two new species formed a highly supported independent subclade within Neolyngbya. Accordingly, three informative domains of the ITS region (D1-D1 0 , Box B and V3) also presented distinct secondary structures compared to previously described species of Neolyngbya, both in structure form and configuration. Overall, analyses of morphology and phylogeny of the 16S rRNA gene and the 16S-23S rRNA ITS region, as well as the secondary structures of ITS region, supported the proposal of two new species within Neolyngbya. Herein, we propose N. intertidalis sp. nov. and N. latusa sp. nov. as new members of Neolyngbya under the provisions of the International Code of Nomenclature for Algae, Fungi and Plants (ICN).

Diseases of tropical reef organisms is an intensive area of study, but despite significant advances in methodology and the global knowledge base, identifying the proximate causes of disease outbreaks remains difficult. The dynamics of infectious wildlife diseases are known to be influenced by shifting interactions among the host, pathogen, and other members of the microbiome, and a collective body of work clearly demonstrates that this is also the case for the main foundation species on reefs, corals. Yet, among wildlife, outbreaks of coral diseases stand out as being driven largely by a changing environment. These outbreaks contributed not only to significant losses of coral species but also to whole ecosystem regime shifts. Here we suggest that to better decipher the disease dynamics of corals, we must integrate more holistic and modern paradigms that consider multiple and variable interactions among the three major players in epizootics: the host, its associated microbiome, and the environment. In this perspective, we discuss how expanding the pathogen component of the classic host-pathogen-environment disease triad to incorporate shifts in the microbiome leading to dysbiosis provides a better model for understanding coral disease dynamics. We outline and discuss issues arising when evaluating each component of this trio and make suggestions for bridging gaps between them. We further suggest that to best tackle these challenges, researchers must adjust standard paradigms, like the classic one pathogen-one disease model, that, to date, have been ineffectual at uncovering many of the emergent properties of coral reef disease dynamics. Lastly, we make recommendations for ways forward in the fields of marine disease ecology and the future of coral reef conservation and restoration given these observations.

“…Currently, Roseofilum is comprised of two formally described species, the type species R. reptotaenium and R. corallyticum isolated from diseased coral tissues (Casamatta et al, 2012; Taylor, 1983). However, metagenomic sequencing work has captured Roseofilum in different environments across the globe (based on NCBI sequences), such as Pelorus Island (Australia), Miyako Island (Japan), Carrie Bow Cay (Belize), Luminao Reef Flat (Guam, United States), and Ft. Lauderdale (United States; Figure 1; Arotsker et al, 2009; Barneah et al, 2007; Buerger et al, 2016; Casamatta et al, 2012; Cooney et al, 2002; Frias‐Lopez et al, 2002; Hutabarat et al, 2018; Klaus et al, 2011; Meyer et al, 2016; Rasoulouniriana et al, 2009; Sato et al, 2010). Although the geographic distribution and chemical diversity of Roseofilum have been studied (Gunasekera et al, 2019; Meyer et al, 2023), there remains a lack of effort to elucidate species in the genus using a combination of morphological, molecular, and genomic data.…”

Benthic cyanobacterial mats (BCMs) are natural phenomena in marine environments. Reports of BCMs occurring across coastal marine environments have increased, partly driven by nutrient loading and climate change; thus, there is a need to understand the diversity involved in the proliferations and potential toxicity of the BCMs. Furthermore, marine cyanobacterial mats are observed growing on and affecting the health of corals with one specific cyanobacterial genus, Roseofilum, dominating the microbial mats associated with black band disease (BBD), a destructive polymicrobial disease that affects corals. To explore the diversity of Roseofilum, cyanobacterial mats from various marine habitats were sampled, and individual isolates were identified based on morphology, 16S rRNA gene phylogenies, 16S–23S ITS rRNA region sequence dissimilarities, and phylogenomics. Four novel species of Roseofilum were isolated from benthic marine mats, three from the coasts of Florida, United States (R. capinflatum sp. nov., R. casamattae sp. nov., and R. acuticapitatum sp. nov.) and one from the coast of France (R. halophilum sp. nov.). Our analyses revealed that Roseofilum associated with coral BBD and those not associated with corals but rather from coastal benthic mats are systematically distinct based on both phylogenetic and phylogenomic analyses. Enzyme‐linked immunosorbent assay (ELISA) and LC–MS data indicated that microcystin production was found in one of the four species.
