It has long been recognized that sponges differ in the abundance of associated microorganisms, and they are therefore termed either 'low microbial abundance' (LMA) or 'high (HMA) sponges. Many previous studies concentrated on dense communities HMA sponges, whereas little is known about microorganisms LMA Here, two from Red Sea, Caribbean one South Pacific were investigated. With up to only five bacterial phyla per sponge, all showed lower phylum-level diversity than typical Interestingly,...
Abstract Marine sponges are generally classified as high microbial abundance (HMA) and low (LMA) species. Here, 16S rRNA amplicon sequencing was applied to investigate the diversity, specificity transcriptional activity of microbes associated with an LMA sponge ( Stylissa carteri ), HMA Xestospongia testudinaria ) sea water collected from central Saudi Arabia coast Red Sea. Altogether, 887 068 denoised sequences were obtained, which 806 661 remained after quality control. This resulted in...
Sponges (Porifera) harbor distinct microbial consortia within their mesohyl interior. We herein analysed the hologenomes of Stylissa carteri and Xestospongia testudinaria, which notably differ in microbiome content. Our analysis revealed that S. has an expanded repertoire immunological domains, specifically Scavenger Receptor Cysteine-Rich (SRCR)-like compared to X. testudinaria. On side, metatranscriptome analyses overrepresentation potential symbiosis-related domains findings provide...
Abstract A main goal of population geneticists is to study patterns gene flow gain a better understanding the structure in given organism. To date most efforts have been focused on studying at either broad scales identify barriers and isolation by distance or fine spatial order inferences regarding reproduction local dispersal. Few studies measured connectivity multiple utilized novel tools test influence both environment geography shaping an Here seascape genetics approach was used insight...
ABSTRACT Comparative genomic studies of closely related taxa are important for our understanding the causes divergence on a changing Earth. This being said, resources available marine intertidal molluscs limited and currently, there few publicly high‐quality annotated genomes species in general. Here we report transcriptome assemblies six Patellogastropoda genome annotations three these ( Scurria scurra , viridula zebrina ). analysis using suggest that recently diverging lineages (10–20 Mya)...
Abstract Aim To understand the origin of most isolated endemic fish fauna Indo‐Pacific, Easter Island (Rapa Nui), and to infer divergence times colonization routes coral reef from their closest relatives. Location Island, Pacific Ocean. Methods Samples ten species were used: six small‐range Rapa Nui Motu Motiro Hiva (Salas y Gómez) (i.e. species) four large‐range southern subtropical species). We present phylogenetic reconstruction results based on mitochondrial (1 5) nuclear 6) loci place...
Abstract Recent coral spawning observations in the central Red Sea show that most scleractinian species release their gametes spring, with a majority of April. There is, however, lack reproductive data for several other species, as well general invertebrates. Here, we document detailed timing 13 one sea anemone, and six echinoderms from an inshore reef off coast Thuwal, Saudi Arabia, spring between April June 2014. Furthermore, inferred presence mature gametes, report month three additional...
Despite the ubiquitous role sponges play in reef ecosystem dynamics, little is known about population-level connectivity these organisms. The general field of population genetics remains its infancy. To date, microsatellite markers have only been developed for few sponge species and no studies using microsatellites conducted Red Sea. Here, with use next-generation sequencing, we characterize 12 novel polymorphic loci common sponge, Stylissa carteri. number alleles per ranged between three...
A species of Inocybe common in Washington, Oregon and British Columbia is documented described as new. The species, I. chondroderma, characterized by these features: pileus with a fulvous disk ochraceous to chamois margin, presence cortina, densely mycelioid stipe base, smooth spores fall phenology. most reliable distinctive feature the blue-green or turquoise reaction response application solution p-dimethylaminobenzaldehyde (PDAB), indicating what likely an indole alkaloid. PDAB use...

Here we report transcriptome assemblies six species Patellogastropoda genome annotations three these (Scurria scurra, Scurria viridula, zebrina). analysis using suggest that was large gene family contraction...
Abstract Elucidating demographic history during the settlement of ecological communities is crucial for properly inferring mechanisms that shape patterns species diversity and their persistence through time. Here, we used genomic data coalescent‐based approaches to elucidate first time dynamics associated with by endemic reef fish fauna one most remote peripheral islands Pacific Ocean, Rapa Nui (Easter Island). We compared nine in order explore responses Pleistocene climatic fluctuations....
Abstract Aim The mutualistic relationship between anemones and anemonefishes is one of the most iconic examples symbiosis. However, while have been extensively studied in terms genetic connectivity, such information lacking entirely for host sea anemones. Here, we provide first on broad‐scale population structure phylogeographical patterns three species anemone, Heteractis magnifica, Stichodactyla mertensii Entacmaea quadricolor . We evaluate if there concordance across several distinct...
Abstract The need to manage threats biodiversity, and do so cost‐effectively, is urgent. Cross‐realm conservation management recognized as a cost‐effective approach, but it requires collaboration between agencies jurisdictions, local knowledge of anthropogenic biodiversity. With its emphasis on stakeholder engagement use structured expert elicitation, Priority Threat Management (PTM) facilitates rapid, cross‐realm planning at the regional scale. We used PTM identify strategies with aim...
Studying population structure and genetic diversity at fine spatial scales is key for a better understanding of demographic processes that influence connectivity. This particularly important in marine benthic organisms rely on larval dispersal to maintain connectivity among populations. Here, we report the results survey ascidian Pyura chilensis from three localities along southeastern Pacific. study follows up previous described break this region only 20 km apart. By implementing...
Abstract Aim Accurate characterization of evolutionary units (species or populations) underlies all ecological and studies is crucial to conservation planning. Seascapes have long been thought be highly permeable gene flow, yet over the last decade building evidence has shown that barriers flow in marine environments are much more common than previously thought. Here, we precisely characterize two tunicate Pyura chilensi s across 26° latitude southeastern Pacific, assess their magnitude...
<title>Abstract</title> Decades of research in population genetics have revealed that genetic divergence between populations and species is not uniformly distributed throughout the genome, but rather exhibits a high degree heterogeneity. This phenomenon has sparked debate regarding evolutionary mechanisms responsible for this variability. study delves into patterns genomic three marine limpet species, <italic>Scurria scurra</italic>, araucana</italic>, ceciliana</italic>, which inhabit both...
