DNA barcoding has attracted attention with promises to aid in species identification and discovery; however, few well-sampled datasets are available test its performance. We provide the first examination of performance a comprehensively sampled, diverse group (cypraeid marine gastropods, or cowries). utilize previous methods for testing employ novel phylogenetic approach calculate intraspecific variation interspecific divergence. Error rates estimated (1) identifying samples against...
Effective conservation requires rigorous baselines of pristine conditions to assess the impacts human activities and evaluate efficacy management. Most coral reefs are moderately severely degraded by local such as fishing pollution well global change, hence it is difficult separate from effects. To this end, we surveyed on uninhabited atolls in northern Line Islands provide a baseline reef community structure, increasingly populated document changes associated with activities. We found that...
The perceived wide geographic range of organisms in the sea, facilitated by ready dispersal waterborne stages, is a challenge for hypotheses marine speciation but boon to efforts conservation. Wide species ranges are especially striking reef-rich Indo-west Pacific, largest and most diverse biogeographic region, extending across half planet. insular biota tropical Pacific characterized wide-ranging provides examples long distance dispersal, with endemism largely confined remote island groups....
SYNOPSIS. The isolation and small size of oceanic islands make them attractive models for studies diversification; the sensitivity their biota makes important subjects extinction. I explore origin island biotas through dispersal in situ diversification, examine fate these since human contact. Island start out depauperate disharmonic, facilitating survival relict taxa stimulating adaptive radiations. often highly restricted range population insular species, together with limited diversity...
The pantropical sea urchin genus Eucidaris contains four currently recognized species, all of them allopatric: E. metularia in the Indo-West Pacific, thouarsi eastern tribuloides both western and Atlantic, clavata at central Atlantic islands Ascension St. Helena. We sequenced a 640-bp region cytochrome oxidase I (COI) gene mitochondrial DNA to determine whether this division into species was confirmed by molecular markers, ascertain their phylogenetic relations, reconstruct history possible...
Abstract Aim The geological and palaeo‐climatic forces that produced the unique biodiversity in Red Sea are a subject of vigorous debate. Here, we review evidence for against hypotheses that: (1) fauna was extirpated during glacial cycles Pleistocene (2) coral reef found refuge within or just outside low sea level stands when conditions were inhospitable. Location Western Indian Ocean. Methods We literature on palaeontological, geological, biological genetic allow us to explore competing...
Evolutionary Synthesis Center (NESCent) in Durham, North Carolina, USA, to discuss approaches and cooperative ventures Indo-Pacific phylogeography.The group emerged with a series of findings: (1) Marine population structure is complex, but single locus mtDNA studies continue provide powerful first assessment phylogeographic patterns.(2) These patterns gain greater significance/power when resolved diversity taxa.New analytical tools are emerging address these analyses multi-taxon...
Humans depend on diverse ocean ecosystems for food, jobs, and sustained well-being, yet many stressors threaten marine life. Extensive research has demonstrated that maintaining biodiversity promotes health service provision; therefore, monitoring the status trends of is important effective ecosystem management. However, there no systematic program evaluating biodiversity. Coordinating existing building a proactive observation network will support efficient, economical resource management...
Nearly all of the recognized species sea slugs in clade Sacoglossa (about 300 taxa) are herbivorous, using a uniseriate radula suctorial feeding. The only exceptions pair monotypic genera ceratiform family Limapontiidae: Olea Agersborg, 1923 from northeastern Pacific, and Calliopaea d'Orbigny, 1837 Atlantic coast Europe Mediterranean. Both feed on eggs other heterobranchs, notably cephalaspideans, lack cerata anterior dorsum. Major differences that C. bellula has more than O. hansineensis...
Patterns of distribution and processes differentiation have often been contrasted between terrestrial marine biotas. The islands Oceania offer an excellent setting to explore this contrast, because the geographic for shallow-water, benthic, organisms are same: myriad strewn across vast Pacific. size species ranges endemism two biogeographic attributes that thought differ markedly biotas in While frequently confined single or archipelagoes throughout Oceania, tend wide very distributions,...
For marine, benthic animals, duration of planktonic larval stages is expected to correlate with dispersal ability, and thus species ranges, at least where necessary reach habitats. Yet past analyses ranges across the insular Pacific show most a weak correlation. So, do larvae matter in determining such an island setting? We analyze extensive dataset on cowries find, again, that estimated does not ranges. Several factors can obscure real correlation, however, including estimation error,...
The frequent late Cenozoic glacial ages were accompanied by sea-level falls of 100–150 m amplitude. These stranded the complex inner-reef platforms and lagoons tropical Pacific islands, while outer-reef-slope habitats persisted, although displaced downslope. effects regressions on bivalves studied examining zonation species across reef systems composition tectonically uplifted islands with, effectively, local low sea stands. I show that qualitative habitat loss (the stranding habitats) was...
The diversity on coral reefs has long captivated observers. We examine the mechanisms of speciation, role ecology in and patterns species distribution a typical reef-associated clade-the diverse colorful Calcinus hermit crabs-to address origin tropical marine diversity. sequenced COI, 16S, H3 gene regions for approximately 90% 56 putative species, including nine undescribed, "cryptic" taxa, mapped their distributions. Speciation is largely peripatric at remote locations. Allopatric pairs are...
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...
Recently collected material from Australia, Japan and Guam allowed us to revise Phyrella describe mookiei sp. nov. We redefine the genus based on combined morphological molecular analyses. unlike most dendrochirotids eviscerate posteriorly. The number of tentacles is variable (14–20), as degree fragmentation calcareous ring, calling into question separation Phyllophorinae Semperiellinae, suggest that Semperiella Thyonidiella are synonymous with Phyrella. recognize five species in...
Three new species of the parasitic isopod subfamily Hemiarthrinae Markham, 1972 are described. Allodiplophryxus unilateralis n. sp. is described from Western Australia, infesting palaemonid shrimp Jocaste lucina (Nobili, 1901), and females differ only other in genus possessing six pleomeres, an asymmetrical first oostegite pleopods restricted to short side body.

Three new species of the bopyrid genus Scyracepon Tattersall, 1905 are described from crabs collected on Pacific Islands: polynesiensis n. sp. Society Islands, S. pseudoliomerae Mariana and biglobosus Line Islands. The first two were found infesting Xanthias lamarckii Pseudoliomera (Xanthidae), a host family for Scyracepon, last was parasitizing Schizophrys aspera (Majidae). now includes 11 species, all but one known single collections, 12 in 9 brachyuran families. discovery three each rare,...
