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...
Sea-level rise (SLR) will greatly alter littoral ecosystems, causing habitat change and loss for coastal species. Habitat is widely used as a measurement of the risk extinction, but because many species are migratory, impact depend not only on its extent, also where it occurs. Here, we develop novel graph-theoretic approach to measure vulnerability migratory network from SLR based population flow through network. We show that reductions in far exceed proportion lost 10 long-distance migrant...
Can genetic adaptation in reef-building corals keep pace with the current rate of sea surface warming? Here we combine population genomics, biophysical modeling, and evolutionary simulations to predict future common coral Acropora millepora on Great Barrier Reef (GBR). Genomics-derived migration rates were high (0.1–1% immigrants per generation across half latitudinal range GBR) closely matched model larval dispersal. Both models indicated prevalence southward along GBR that would facilitate...
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...
Abstract Real patterns of ecological connectivity are seldom explicitly or systematically accounted for systematic conservation planning, in part because commonly used decision support systems can only capture simplistic notions connectivity. Conventionally, the surrogates to represent plans have assumed connection between two sites be symmetric strength. In reality, linkages rarely and often strongly asymmetric. Here, we develop a novel formulation that enabled us incorporate asymmetric...
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...
Population connectivity, which is essential for the persistence of benthic marine metapopulations, depends on how life history traits and environment interact to influence larval production, dispersal survival. Although we have made significant advances in our understanding spatial temporal dynamics these individual processes, developing an approach that integrates entire population connectivity process from reproduction, through dispersal, recruitment individuals has been difficult. We...
Multinational conservation initiatives that prioritize investment across a region invariably navigate trade-offs among multiple objectives. It seems logical to focus where several objectives can be achieved efficiently, but such multi-objective hotspots may ecologically inappropriate, or politically inequitable. Here we devise framework facilitate regionally cohesive set of marine-protected areas driven by national preferences and supported quantitative prioritization analyses, illustrate it...
Incorporating connectivity into the design of marine protected areas (MPAs) has met with conceptual, theoretical, and practical challenges, which include: 1) need to consider for multiple species different dispersal abilities, 2) role played by variable habitat quality in determining spatial patterns connectivity. We propose an innovative approach, combining biophysical modeling a routinely‐used tool marine‐reserve (Marxan), address both challenges using ecologically‐informed parameters....
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...
Abstract Globally, protected areas are being established to protect biodiversity and promote ecosystem resilience. The typical spatial conservation planning process leading the creation of these focuses on representation replication ecological features, often using decision support tools such as Marxan. Yet, despite important role connectivity has in metapopulation persistence resilience, Marxan currently requires manual input or specialized scripts explicitly consider connectivity. ‘Marxan...
We integrated coral reef connectivity data for the Caribbean and Gulf of Mexico into a conservation decision-making framework designing regional scale marine protected area (MPA) network that provides insight ecological political contexts. used an ocean circulation model to simulate eight spawning events from 2008–2011, applying maximum 30-day pelagic larval duration 20% mortality rate. Coral dispersal patterns were analyzed between reefs across jurisdictional zones identify spatial...
Seascape ecology, the marine-centric counterpart to landscape is rapidly emerging as an interdisciplinary and spatially explicit ecological science with relevance marine management, biodiversity conservation, restoration. While important progress in this field has been made past decade, there no coherent prioritisation of key research questions help set future agenda for seascape ecology. We used a 2-stage modified Delphi method solicit applied from academic experts ecology then asked...
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...

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...
Abstract The potential of reef‐building corals to adapt increasing sea‐surface temperatures is often debated but has rarely been comprehensively modeled on a region‐wide scale. We used individual‐based simulations model adaptation warming in coral metapopulation comprising 680 reefs and representing the whole Central Indo‐West Pacific. Encouragingly, some reefs—most notably Vietnam, Japan, Taiwan, New Caledonia southern half Great Barrier Reef—exhibited high capacity for and, our model,...
Abstract Coral reefs worldwide are threatened by thermal stress caused climate change. Especially devastating periods of coral loss frequently occur during El Niño‐Southern Oscillation (ENSO) events originating in the Eastern Tropical Pacific (ETP). Niño‐induced is considered primary threat to ETP reefs. An increase frequency and intensity ENSO predicted coming decades threatens a pan‐tropical collapse During 1982–1983 Niño, most Galapagos Islands collapsed, many more region were decimated...
