Abstract Marine prairies play various crucial roles in marine ecosystems. The seagrasses that compose them are one of the most important components engineering the marine coastal system, providing significant spatial niches. Some of the seagrasses found in marine prairies are protected, and it is not recommended to sample them with destructive methods. Non-destructive methods such as remote sensing have been proposed as important means of studying these protected species. In the present study, the acoustic scattering properties of Cymodocea nodosa were studied with two different in / ex situ experiments conducted on a Turkish Mediterranean coast using a scientific echosounder (206 kHz split beam transducer) in different months over the years 2011 and 2012. After a series of acoustic processes, correlations and regression equations were established between different acoustic parameters of the Elementary Distance Sampling Units and biometric traits of below/above ground parts of the seagrass. The relationships were logarithmically established producing first a Rayleigh zone, followed by a geometrical zone that occurred with increased biometrics. No seasonal difference occurred in the relationships for the above-ground parts. Unlike the leaves, seagrass sheaths demonstrated unstable echo energy, inconsistent relationships, and unexplained acoustic responses over the span of several months. Regarding leaf density changing in time, significant relationships were explained as a function of the acoustic zones. Four points were highlighted to explain the differences in the estimations between the two experiments; i) the backscattering strengths depended on strength of biomass and its fractions (leaf area, shoot density and volume) between the two experiments, ii) the first experiment measured backscattering strength from individual specimens, but the second experiment was performed on the total biomass of seagrass per unit area, iii) different frequency response to the biometrics occurred in the two experiments, and iv) the non-linear effect of the sheath could not be separated from that of the leaf during the second experiment. The present study was the first attempt to characterize relationships between the biometric and acoustic backscattering properties of C. nodosa , and will guide researchers in future use of non-destructive methods.

Abstract Axenic cultures of the green seaweed Ulva mutabilis were inoculated with bacteria providing essential algal growth and morphogenesis-promoting factors (AGMPFs) and were exposed to temperature shifts from 18 °C to 30 °C. The temperature-dependent effect of bacteria on longitudinal algal growth and the molecular composition of the chemosphere in the algal culture medium was explored. The reductionist tripartite model system of U. mutabilis , Roseovarius sp. MS2, and Maribacter sp. MS6 was applied as a reference and has been changed by substituting Roseovarius with isolates that phenocopy this strain. Rathayibacter festucae IH2 and Roseovarius aestuarii G8 boosted growth at 18 °C but slowed it down at 30 °C. Additional inoculation of Roseovarius sp. MS2 mitigated these adverse bacterial effects partially. At 30 °C, the molecular profile of the chemosphere differed dramatically between all tested tripartite communities, indicating different traits of the same bacterium with changing temperatures. Functional examinations should, therefore, accompany microbiome analysis to detect changing traits with the same microbiome composition.

Abstract The records of the unarmored dinoflagellate Gynogonadinium aequatoriale have been restricted to the western equatorial and the eastern tropical Pacific Ocean. The genus is reported for the first time in the Mediterranean Sea from the coast of Taranto, Ionian Sea. This is a distinctive taxon that can only be confused with the cosmopolitan Pseliodinium fusus (= Ceratoperidinium falcatum ). A comparison of these two species is provided.

Abstract The seaweed Gracilariopsis lemaneiformis is widely cultivated in the southern and northern coasts of China, and is mainly used for agar extraction and abalone feed. The cultivated strain of G. lemaneiformis 981 has various advantages over the wild type such as growth rate and high-temperature tolerance. Therefore, it is necessary to investigate the differences between the wild-type and cultivated G. lemaneiformis . Here, 648 up-regulated and 837 down-regulated proteins were screened using the isobaric tags for relative and absolute quantitation (iTRAQ) technique, and these differentially expressed proteins (DEPs) were concentrated in the pathways including “Ribosome”, “Photosynthesis-antenna proteins”, “alpha-Linolenic acid metabolism”, and “Phenylpropanoid biosynthesis”. The most prominent pathway was “Ribosome”, namely, 116 out of 119 ribosome-associated proteins were up-regulated in G. lemaneiformis 981 compared to the wild type. Subsequently, multiple reaction monitoring (MRM) validated the credibility of the iTRAQ results. Finally, “Phenylpropanoid biosynthesis” and “Photosynthesis-antenna proteins” pathways were also found to be significantly changed in G. lemaneiformis 981 validated by gene expression profiling analysis. Altogether, these results, in combination with chlorophyll fluorescence parameters, unveiled the possible mechanism of differences in growth and anti-abiotic stresses between the wild-type and cultivated G. lemaneiformis , which would provide a reference for breeding of excellent seaweeds.

Abstract This article is a personal impression of the key scientists who contributed to the study of marine mycology over past 174 years, especially those the author met during his career studying this unique group of fungi. Marine mycology has been a journey of discovery from a few species to nearly 2000 taxa in nine fungal phyla. Techniques for their study have advanced from morphological observations, to the use of scanning and transmission electron microscopy, to the development of high-throughput sequencing technology and the unravelling of the genomes of selected species. Thoughts on the conservation of marine fungi, their adaptation to climate change and potential role in the decomposition of plastics are briefly considered.

Abstract Brine discharged from seawater desalination plants impacts marine life by exposure to increased salinity and, in some cases, temperature. However, the responses of individual species to such stress remains poorly known yet their understanding is essential for assessing and predicting the impacts of seawater desalination plants. In this study, unialgal cultures obtained by the germling emergence method of 34 taxa representative of the Rhodophyta, Chlorophyta and Phaeophyceae seaweeds in the Arabian Gulf, and isolated from the vicinity of two large desalination plants in Kuwait, were subjected to increased temperature and salinity under experimental conditions in the laboratory. The dataset is complemented by measurements of seawater temperature and salinity obtained at increasing distances from the outfalls of desalination plants and along the Kuwaiti coastline including from two pristine areas, Boubiyan and Fintas. Chlorophyta, especially Ulva spp., and Phaeophyceae displayed remarkable tolerance against hypersaline and thermal stress, suggesting that this group can cope better with adverse environmental conditions. Members of the Rhodophyta were considerably more sensitive to temperature increases.

Abstract Here, macroalgal isotopic values from Loch Creran, Western Scotland, were documented to determine the suitability of paired stable isotope analysis for identifying macroalgal-derived organic carbon sources in a fjordic sea loch. Variability in isotopic values ( δ 13 C and δ 15 N) was evident within individual thalli of fucoid and kelp species, at the replicate level and between sampling localities. There were few consistent phylogenetic correlates in the isotopic values of macroalgae. The δ 13 C ranges did, however, provide insight into differentiating between carbon sources more broadly, such as terrestrial from marine and between macrophyte lineages. As such, δ 13 C could be indicative of the presence of macroalgal carbon sources within pools of organic matter but will likely be ineffective at separating these sources to lower taxonomic levels. Consequently, if these data are used alone to discriminate between macroalgal carbon sources and their relative contribution to a sedimentary pool of organic matter, the development of accurate conclusions will be challenging. The findings presented here demonstrate the need for complementary techniques or multi-tracer approaches to aid in the differentiation between macroalgal carbon sources to lower taxonomic levels rather than relying on stable isotopes as a biomarker alone.

Abstract Although many novel marine fungi have been described from Indian mangroves, a significant number of mangroves in India have not been thoroughly investigated for marine fungi. This study highlights the diversity of marine fungi inhabiting dead and decaying wood of Avicennia marina and Rhizophora mucronata, collected from Thengaithittu and Veerampattinam mangroves of Pondicherry, Puducherry State, India. Through microscopic examination, a total of 52 species (in 48 genera) of marine fungi were identified, with 50 species (in 46 genera) belonging to the Ascomycota and 2 species (in 2 genera) belonging to the Basidiomycota. Previous studies recorded 69 marine fungi from Ariyankuppam and Mahé mangroves of Puducherry, and this study contributes 22 new records of marine fungi to this region. In this study, the phylogenetic placement of Rhizophila marina was determined, and this fungus was found to belong to the family Diatrypaceae.

Abstract We reevaluated species diversity of the brown alga Lobophora in Vietnam’s Con Co Marine Protected Area (MPA), where only one species had previously been reported. Integrating morphological, ecological, and molecular analyses, we redefined the genus diversity, identifying nine species including two new ones: L. asiatica, L. boussoleae, L. lamourouxii, L. obscura1, L. pachyventera3, L. thailandensis, L. quangtriensis sp. nov., L. vietnamensis sp. nov., and Lobophora sp.1VNA. Lobophora variegata, the sole species previously reported, was absent. This study expands the number of Vietnam’s documented Lobophora species to 11. This work reevaluated Lobophora diversity in Vietnam based on a small island, contributing valuable seaweed diversity reference data for Con Co MPA management. Notably, within the MPA, Lobophora species exhibited no coral-aggressiveness, potentially serving as a health indicator for coral reef communities.
