Background: A single specimen of was collected from a dendrophylliid coral by trimix SCUBA diving at a depth of 75 m during fieldwork around Jejudo Island, Korea in 2020. The morphology of the specimen corresponds closely to the main diagnostic characters of the holotype, especially in the presence of a distinct tubercle on the eyestalk, as well as the second pereiopod with fusiform setae along the dorsal border of the ischium.
New Information: The genus had previously not been reported from Korean waters. Herein, colour photographs are provided, as well as an illustrated description including previously unreported characteristics.

This study aimed to achieve two main objectives: first, to determine whether the virulence factors of symbiotic bacteria of entomopathogenic nematodes (EPNs) against insect hosts are cell-associated or secreted, and to shed light on the underlying mechanisms of pathogenicity; and second, to identify and evaluate the standalone pathogenicity of symbiotic bacteria associated with entomopathogenic nematodes against Tenebrio molitor. Three bacterial species, Xenorhabdus nematophila (A41, SC, A18 and SF), Photorhabdus kayaii, and P. thracensis, were isolated and characterized via phylogenetic analysis of 16S-rRNA and gyrB genes.

The record-breaking 2019-2020 Australian wildfires have been primarily linked to climate change and its internal variability. However, the meteorological feedback mechanisms affecting smoke dispersion and wildfire emissions on a synoptic scale remain unclear. This study focused on the largest wildfires occurring between December 25, 2019 and January 10, 2020, under the enhanced subtropical high, when the double peak in wildfire evolution was favored by sustained low humidity and two synchronous increases in temperature and wind.

Ciliates often form symbiotic associations with other microorganisms, both prokaryotic and eukaryotic. We are now starting to rediscover the symbiotic systems recorded before molecular analysis became available. Here, we provide a morphological and molecular characterization of a symbiotic association between the ciliate Paramecium tritobursaria and the yeast Rhodotorula mucilaginosa (syn.

Photosymbiosis, a mode of mixotrophy by algal endosymbiosis, provides key advantage to pelagic life in oligotrophic oceans. Despite its ecological importance, mechanisms underlying its emergence and association with the evolutionary success of photosymbiotic lineages remain unclear. We used planktonic foraminifera, a group of pelagic test-forming protists with an excellent fossil record, to reveal the history of symbiont acquisition among their three main extant clades.
View Article and Find Full Text PDFA collection of coral symbiotic crabs (Trapezioidea) from the South China Sea reports a total of 24 species, including 12 species of Trapeziidae (including one new record: Trapezia plana Ward, 1941), four species of Domeciidae, and eight species of Tetraliidae (including one new record: Tetralia brengelae Trautwein, 2007). Live color and mitochondrial cytochrome oxidase I (COI) sequence data of all species are provided.
