Tropical reefs shelter one quarter to third of all marine species but the coral that construct are now at risk extinction. Because traditional methods for assessing reef diversity extremely time consuming, taxonomic expertise many groups is lacking, and organisms thought be less vulnerable extinction, most discussions conservation focus on maintenance ecosystem services rather than biodiversity loss. In this study involving three major oceans with growth, we provide new estimates based...
Significance Tests of biodiversity theory have been controversial partly because alternative formulations the same seemingly yield different conclusions. This has a particular challenge for neutral theory, which dominated tests over last decade. Neutral attributes differences in species abundances to chance variation individuals’ fates, rather than traits. By identifying common features models, we conduct uniquely robust test across global dataset marine assemblages. Consistently, vary more...
The cryptofauna associated with coral reefs accounts for a major part of the biodiversity in these ecosystems but has been largely overlooked estimates because organisms are hard to collect and identify. We combine semi-quantitative sampling design DNA barcoding approach provide metrics diversity reef-associated crustacean. Twenty-two similar-sized dead heads Pocillopora were sampled at 10 m depth from five central Pacific Ocean localities (four atolls Northern Line Islands Moorea, French...
Marine biodiversity underpins ecosystem health and societal well-being. Preservation of hotspots is a global challenge. Molecular tools, like DNA barcoding metabarcoding, hold great potential for monitoring, possibly outperforming more traditional taxonomic methods. However, metabarcoding-based assessments are limited by the availability sequences in reference databases; lack thereof results high percentages unassigned sequences. In this study, we (i) present current status known vs....
We investigated the phylogenetic relationships among monogenean parasites of Chaetodontidae (butterflyfishes) from Indo‐West Pacific Ocean. Molecular phylogenies selected taxa within Dactylogyridae, including ancyrocephaline butterflyfishes, based on two nuclear and one mitochondrial gene fragments (complete 18S rDNA, partial 28S rDNA (D1‐D3), 16S rDNA) were reconstructed using parsimony, maximum likelihood Bayesian inference methods. Our results show non‐monophyletic nature fauna...
High-throughput sequencing (HTS) of DNA barcodes (metabarcoding), particularly when combined with standardized sampling protocols, is one the most promising approaches for censusing overlooked cryptic invertebrate communities. We present biodiversity estimates based on cytochrome c oxidase subunit 1 (COI) gene coral reefs Gulf Aqaba, a semi-enclosed system in northern Red Sea. Samples were obtained from devices (Autonomous Reef Monitoring Structures (ARMS)) deployed 18 months. barcoding...
SUMMARY In the present study, we describe complete mitochondrial (mt) genome of Atlantic salmon parasite Gyrodactylus salaris , first for any monogenean species. The circular is 14 790 bp in size. All 35 genes recognized from other flatworm genomes were identified, and they are transcribed same strand. protein-coding ribosomal RNA (rRNA) share gene arrangement as those published previously neodermatan mt (representing cestodes digeneans only), has an overall A+T content 65%. Three transfer...
Abstract Aim To investigate the phylogeographical patterns of two poorly dispersing but widely distributed monogenean species, Haliotrema aurigae and Euryhaliotrematoides grandis , gill parasites coral reef fishes from family Chaetodontidae. Location South Pacific Ocean (SPO). Methods Sequence data mitochondrial cytochrome oxidase subunit I (COI) gene were obtained samples five localities SPO (Heron Island, Lizard Moorea, Palau Wallis) for parasite species. Phylogenetic genetic diversity...
Small cryptic invertebrates (the cryptofauna) are extremely abundant, ecologically important, and species rich on coral reefs. Ongoing ocean acidification is likely to have both direct effects the biology of these organisms, as well indirect through cascading impacts their habitats trophic relationships. Naturally acidified been important model systems for studying complex interactions because entire communities that adapted environmental conditions can be analyzed. However, few studies...
Abstract Background Microbes play vital roles across coral reefs both in the environment and inside upon macrobes (holobionts), where they support critical functions such as nutrition immune system modulation. These highlight potential ecosystem-level importance of microbes, yet most knowledge microbial on is derived from a small set holobionts corals sponges. Declining seawater pH — an important global reef stressor can cause change reefs, providing opportunity to study role microbes at...

Clitellata (earthworms, leeches, and allies) is a clade of segmented annelid worms that comprise more than 5000 species found worldwide in many aquatic terrestrial habitats. According to current views, the first clitellates were either (marine or freshwater) terrestrial. To address this question further, we assessed phylogenetic relationships among using parsimony, maximum likelihood Bayesian analyses 175 18S ribosomal DNA sequences. We then defined two ecological characters (Habitat...
Recently, the Census of Marine Life has explored methods to assess coral reef diversity by combining standardized sampling (to permit comparison across sites) with molecular techniques make rapid counts species possible). To date, this approach been applied geographically broad scales (seven sites spanning Indian, Pacific and Atlantic Oceans), focusing on similar habitats at all (10–12 m forereef). Here we examine crustacean spatial patterns for a single atoll, comparing results four...
Whilst searching for a molecular method to identify the different species of Raoultella and Klebsiella oxytoca, it was observed that OXY-1 OXY-2 β-lactamase-producing K. oxytoca isolates displayed two distinguishable enterobacterial repetitive intergenic consensus (ERIC)-1R profiles. It hypothesized groups chromosomal β-lactamases might correspond strains in taxon. To confirm this hypothesis, clinical reference were studied by determination sequence their bla OXY genes, partial fragment 16S...
During this step, you will be assembling the ARMS units from individual parts. The unit is a stack of alternating openlayers and closed layers. layers contain cross-shaped structure dividing in four compartments, providing 'cave-like' spaces for organisms. very first space, at bottom should always layer top open. Another important feature that plate lay flat on base plate. No space created between orderto avoid creating an extra colonization.
