Abstract Identifying species boundaries within morphologically indistinguishable cryptic complexes is often contentious. For the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Sternorrhyncha: Aleyrodoidea: Aleyrodidae), lack of a clear understanding about genetic limits numerous groups and biotypes so far identified has resulted in consistency application terms, approaches used to apply them our what structure B. means. Our response been use mitochondrial gene cytochrome oxidase one...
Connectivity among marine populations is critical for persistence of metapopulations, coping with climate change, and determining the geographic distribution species. The influence pelagic larval duration (PLD) on connectivity has been studied extensively, but relatively little known about other biological parameters, such as survival behavior larvae, fecundity adults, population connectivity. Furthermore, interaction between seascape (habitat structure currents) these parameters unclear. We...
Deep coral reefs (that is, mesophotic ecosystems) can act as refuges against major disturbances affecting shallow reefs. It has been proposed that, through the provision of propagules, such deep may aid in reef recovery; however, this "reseeding" hypothesis remains largely untested. We conducted a genome-wide assessment two scleractinian species with contrasting reproductive modes, to assess potential for connectivity between (40 m) and (12 depths on an isolated system Western Atlantic...
We call for journals to commit requiring open data be archived in a format that will simple and clear readers understand use. If applied consistently, these requirements allow contributors acknowledged their work through citation of data, facilitate scientific progress.
The relative importance of factors that may promote genetic differentiation in marine organisms is largely unknown. Here, contributions to population structure from a biogeographic boundary, geographical distance and the distribution suitable habitat were investigated Axoclinus nigricaudus, small subtidal rock-reef fish, throughout its range Gulf California. A 408-bp fragment mitochondrial control region was sequenced 105 individuals. Variation significantly partitioned between 28 36...
Coral reefs are hotspots of biodiversity, yet processes diversification in these ecosystems poorly understood. The environmental heterogeneity coral reef environments could be an important contributor to diversification, however, evidence supporting ecological speciation corals is sparse. Here, we present data from a widespread species that reveals strong association host and symbiont lineages with specific habitats, consistent distinct, sympatric gene pools maintained through...
Dispersal of planktonic larvae can create connections between geographically separated adult populations benthic marine animals. How geographic context and life history traits affect these is largely unresolved. We use data from genetic studies (species level FST) teleost fishes combined with linear models to evaluate the importance transitions biogeographic regions, distance, egg type (benthic or pelagic eggs), larval duration (PLD), marker as factors affecting differentiation within...
Population genomic approaches are making rapid inroads in the study of non-model organisms, including marine taxa. To date, these studies have predominantly focused on rudimentary metrics describing spatial and environmental context their region (e.g., geographical distance, average sea surface temperature, salinity). We contend that a more nuanced considered approach to quantifying seascape dynamics patterns can strengthen population investigations help identify spatial, temporal, factors...
Abstract Seascape genetics is the study of how spatially variable structural and environmental features influence genetic patterns marine organisms. conceptually linked to landscape this likeness frequently allows investigators use similar theoretical analytical methods for both seascape genetics. But, physical attributes ocean biological organisms that live in sea, especially large spatial scales high dispersal ability many organisms, differ from those terrestrial have typified studies....
targeted conservation and management programs are crucial for mitigating anthropogenic threats to declining biodiversity.Although evolutionary processes underpin extant patterns of biodiversity, it is uncommon resource managers explicitly consider genetic data in prioritization.Genetic information inherently relevant because describes diversity, population connectedness, history; thereby typifying their behavioral traits, physiological climate tolerance, potential, dispersal...
The Genomic Observatories Metadatabase (GeOMe, http://www.geome-db.org/) is an open access repository for geographic and ecological metadata associated with biosamples genetic data. Whereas public databases have served as vital repositories nucleotide sequences, they do not accession all the required or evolutionary analyses. GeOMe fills this need, providing a user-friendly, web-based interface both data contributors recipients. allows to create customized yet standard-compliant spreadsheet...
Larval dispersal by ocean currents is a critical component of systematic marine protected area (MPA) design. However, there lack quantitative methods to incorporate larval in support increasingly diverse management objectives, including local population persistence under multiple types threats (primarily focused on retention within and between locations) benefits unprotected populations fisheries export from locations fishing grounds). Here, we present flexible MPA design approach that can...
Abstract Aim To test hypothesized biogeographic partitions of the tropical Indo‐Pacific Ocean with phylogeographic data from 56 taxa, and to evaluate strength nature barriers emerging this test. Location The Ocean. Time period Pliocene through Holocene. Major taxa studied Fifty‐six marine species. Methods We tested eight hypotheses for partitioning using a novel modification analysis molecular variance. Putative gene flow were evaluated pairwise Φ ST , these distributions compared randomized...
Genomic data are being produced and archived at a prodigious rate, current studies could become historical baselines for future global genetic diversity analyses monitoring programs. However, when we evaluated the potential utility of genomic from wild domesticated eukaryote species in world's largest repository, found that most datasets (86%) lacked spatiotemporal metadata necessary biodiversity surveillance. Labor-intensive scouring subset published papers yielded geospatial coordinates...
Abstract Genetic diversity within species represents a fundamental yet underappreciated level of biodiversity. Because genetic can indicate resilience to changing climate, its measurement is relevant many national and global conservation policy targets. Many studies produce large amounts genome‐scale data for wild populations, but most (87%) do not include the associated spatial temporal metadata necessary them be reused in monitoring programs or acknowledging sovereignty nations Indigenous...
Abstract Understanding how biodiversity originates and is maintained are fundamental challenge in evolutionary biology. Speciation a continuous process progression along this continuum depends on the interplay between forces driving divergence promoting genetic homogenisation. Coral reefs broadly connected yet highly heterogeneous ecosystems, with gene flow at small spatial scales might therefore be common. Genomic studies increasingly revealing existence of closely related sympatric taxa...
In marine organisms, a pelagic larval stage increases the opportunities for long–distance dispersal and is often associated with little genetic differentiation over large geographical distances. Here we test hypothesis that early life–history characteristics, including spatial distributions, affect rates of and, therefore, levels partitioning among three Gulf California reef fishes: Axoclinus nigricaudus, Malacoctenus hubbsi; Ophioblennius steindachneri;. These blennioid fishes have markedly...
Divergent natural selection across environmental gradients has been acknowledged as a major driver of population and species divergence, however its role in the diversification scleractinian corals remains poorly understood. Recently, it was demonstrated that brooding coral Seriatopora hystrix algal endosymbionts (Symbiodinium) are genetically partitioned reef environments (0-30 m) on far northern Great Barrier Reef. Here, we explore potential mechanisms underlying this differentiation...
Dispersal is a fundamental species characteristic that should directly affect both rates of gene flow among spatially distributed populations and opportunities for speciation. Yet no single trait associated with dispersal has been demonstrated to micro- macroevolutionary patterns diversity across diverse biological assemblage. Here, we examine genetic differentiation richness in reef fishes, an assemblage over 7,000 comprising approximately one-third the extant bony fishes one-tenth living...

Overfishing threatens the sustainability of coastal marine biodiversity, especially in tropical developing countries. To counter this problem, about 200 governments worldwide have committed to protecting 10%–20% national areas. However, associated impacts on fisheries productivity are unclear and could weaken food security hundreds millions people who depend diverse largely unregulated fishing activities. Here, we present a systematic theoretic analysis ability reserves rebuild under such...
