We studied the genetic diversity of a coral reef fish species to investigate origin differentiation. A total 727 Acanthurus triostegus collected from 15 locations throughout Pacific were analyzed for 20 polymorphic loci. The structure showed limited internal disequilibrium within each population; 3.7% loci significant Hardy-Weinberg disequilibrium, mostly associated with Adh*, and we subsequently removed this locus further analysis geographic pattern. A. tropical Ocean revealed strong...
This study investigated the influence of reproductive strategy (benthic or pelagic eggs) and habitat preferences (lagoon outer slope) on both diversity genetic differentiation using a set populations seven coral reef fish species over different geographic scales within French Polynesia. We hypothesized that Holocene sea‐level decrease contributed to severe reduction population size for inhabiting lagoons subsequent diversity. Conversely, we proposed stable environments, such as slope, should...

Molecular tools and analyses have played pivotal roles in uncovering the processes patterns of biodiversity Indian Pacific oceans. However, integrating genetic results into management conservation objectives has been challenging, with few examples that show practical applicability. This review aims to address some perceived barriers an enhanced approach integrates molecular data goals, by reviewing papers relevant both fisheries Indo-Pacific region, particularly respect phylogeography,...
Abstract Little is known about the spatial and temporal scales at which planktonic organisms are genetically structured. A previous study of mitochondrial DNA (mtDNA) in holoplanktonic chaetognath Sagitta setosa revealed strong phylogeographic structuring suggesting that Northeast (NE) Atlantic, Mediterranean Black Sea populations disjunct. The present used a higher sampling intensity combination four microsatellite markers to reveal population between within basins. Between basins, both...
Kin selection plays an important role in the evolution of social behaviour terrestrial systems. The extent to which kin influences marine systems is largely unexplored. Generally, it considered that irrelevant systems, because assumed dispersing larval phase organisms will break up associations. Here, we challenge this assumption and investigate opportunity for a coral reef fish: humbug damselfish Dascyllus aruanus. This fish lives groups composed large male number smaller females...
Abstract We used exon‐primed, intron‐crossing polymerase chain reaction (EPIC‐PCR) amplification to assay variation in nuclear loci some teleost fishes (Carangidae, Centropomidae, Chaetodontidae, Clupeidae, Holocentridae, Moronidae, Mullidae, Pomacentridae, Scombridae, Siganidae). designed primers the conserved regions flanking splice sites of consecutive exons different genes, allowing 17 putative introns. Among satisfactory amplified systems, 14 showed length polymorphism with 2–14 alleles.
In the past decades, anthropogenic disturbance has increased in marine costal habitats, leading to dramatic shifts population size structure of various species. temperate region, gorgonian coral (Corallium rubrum) is one major disturbed species, mostly owing exploitation its red skeleton for jewellery purposes.

Previous studies on the common ragworm Hediste diversicolor (Polychaeta: Nereididae) revealed a marked genetic fragmentation across its distribution and occurrence of sibling taxa in Baltic Sea. These results suggested that phylogeographic patterns H. could reflect interactions between cryptic differentiation multiple colonization events. This study aims to describe large-scale structuring trace origins types described Samples (2 < n 28) were collected at 16 locations NE Atlantic coasts...
Abstract Giant clam populations have been over‐exploited throughout their range over the past decades for meat and shells. Tridacna maxima, commonly known as ‘small giant clam’, has remained relatively untargeted by fishers in areas where larger species occur (e.g. squamosa ), high densities of are still observed on some isolated enclosed reefs Central Pacific. However, it is unclear whether reported discrepancies worldwide reflect differences fishing pressure only or a combination...
The scleractinian coral Pocillopora damicornis type β is known to present a mixed reproduction mode: through sexual reproduction, new genotypes are created, while asexual insures their propagation. In order investigate the relative proportion of each mode in P. populations from Reunion Island, Indian Ocean, clonal propagation along west coast was assessed four sampling sites with increasing geographical distance between sites. Coral colonies were sampled either exhaustively, randomly or...
Although fish is an important source of nutrients, including some the healthiest proteins, long-chain fatty acids, and essential selenium, species at top food chain frequently contain large amounts toxic mercury (Hg). The provisional tolerable weekly intake (PTWI) Hg from consumption calculated total concentration assuming that all speciated as organic methylmercury (MeHg). Using high energy-resolution X-ray absorption near-edge structure (HR-XANES) spectroscopy, we show blue marlin (Makaira...
The European Marine Omics Biodiversity Observation Network (EMO BON) is an initiative of the Biological Resource Centre (EMBRC) to establish a persistent genomic observatory among designated coastal marine sites, sharing same protocols for sampling and data curation. Environmental samples are collected from water column, at some soft sediments hard substrates (Autonomous Reef Monitoring Structures - ARMS), together with set mandatory discretionary metadata (including Essential Ocean...
The susceptibility of species to habitat changes depends on which ecological drivers shape individual fitness components. To date, only a few studies have quantified components such as the Lifetime Reproductive Success across multiple generations in wild marine species. Because long-term sampling effort, information is available for population orange clownfish, Amphiprion percula, from Kimbe Island (Papua New Guinea). Previous work clownfish near suggests that there little adaptive potential...

Although fish is an important source of nutrients, including some the healthiest proteins, long-chain fatty acids, and essential selenium, species at top food chain often contain high levels mercury (Hg). The provisional tolerable weekly intake (PTWI) Hg from consumption calculated based on total concentration Hg, assuming that all in form organic methylmercury (MeHg). However, recent findings indicate species, even predators, may have concentrations but very low proportions MeHg. In this...
Human activities and climate change increasingly threaten biodiversity marine resources, demanding effective management programs that can adapt over time. A critical aspect of this effort is understanding population connectivity, i.e. the exchange individuals among fragmented subpopulations. Population connectivity a crucial process supporting persistence, regeneration, evolution species distribution, with significant implications for ecosystem function biodiversity. Connectivity data are...
