“…The contribution of freshwater species to the Israeli coastal zone is 29 %. The presence of fresh water species in the marine coastal community is also ob ser ved in other seas (Beljakova & Fushtey 2004, Gorin et al 2016, Vinogradova & Bryantseva 2017, Miroshnichenko 2021 but differs only in their proportion. Also, four in dicator species were identified, which are freshwater ones.…”

“…Twentyfive dried samples of marine benthos from the coastal sites were soaked in water with a salinity of 35 ‰ for 1 hour be fore processing. The slides with samples were examined in native preparations (Barbour et al 1999, Miroshnichenko 2021) in a light microscope Bresser BioScience Trino (Germa ny) with Levenhuk M1000 Plus microscope digital camera at the ×400 and ×1000 magnifications.…”

The work aims the study the species diversity and ecology of Cyanobacteria in the benthos on the Israeli coast of the Mediterranean Sea. As a result, 24 taxa of Cyanobacteria were found. Seven taxa were noted for the first time for this sea: Aphanocapsa incerta, Aphanothece nidulans, Chlorogloea cf. microcystoides, Pseudanabaena mucicola, Chroococcus sp., Gloeocapsopsis sp., Trichocoleus sp. Most Cyanobacteria species were benthic (90 %) and marine (67 %). There were only four indicators of saprobity, and all of them were freshwater species common in oligosaprobic and beta-mesosaprobic waters. Most species had a wide geographic distribution. Species marked of boreal (10 %), boreal-tropical (38 %), arctic-boreal-tropic (29 %) and cosmopolites (24 %) groups. The species richness of Cyanobacteria increased in the sites with the maximal anthropogenic loads from industrial and urban areas of the central Israel, and the minimal ones were in the protected areas.

“…Few intertidal cyanobacteria strains have been described as MAA producers (Sinha et al 2007), especially from polar habitats other than mat communities (Quesada et al 1998;Joshi et al 2018). An ecological survey of the intertidal polar region on Kola Bay has shown higher species abundance in upper intertidal zones, with the majority of cyanobacterial strains (70%) as benthic on natural substrates (Miroshnichenko 2021), similar to H. branconii CENA392. Out of the 46 cyanobacterial genera identified by morphology alone, no Halotia strains were reported.…”

Antarctica poses numerous challenges to life such as cold shock, low nutrient concentrations, and periodic desiccation over a wide range of extreme temperatures. Cyanobacteria survive this harsh environment having evolved adaptive metabolic plasticity to become the dominant primary producers. The type strain cyanobacterium Halotia branconii CENA392 was isolated from an Antarctic intertidal seashore. The complete circular genome of this strain is presented herein, which was assembled using long‐sequence reads. The genome encoded some stress‐related genes associated with low‐temperature adaptation and biosynthesis of mycosporine‐like amino acid (MAA) photoprotective compounds. Empirical experimentation demonstrated constitutive production of the MAA porphyra‐334 and total carotenoids without exposure to low temperatures or ultraviolet radiation stress. Phylogenetic analysis provided insights on taxonomic placement and evolutionary history of some annotated genes. These data exemplify the importance of generating complete quality genome sequences of microorganisms isolated from extreme intertidal environments, facilitating in‐depth evaluation of ecological and taxonomic inferences.
