Significance Our results indicate that, even in highly diverse systems like coral reefs, we can no longer assume that the erosion of species diversity be discounted by high probability functional redundancy: i.e., several support same function. Indeed, show fish tend to disproportionately pack into a few particular functions while leaving many vulnerable, they are supported just one species. Even Coral Triangle, which has concentration tropical-reef fishes, may experience loss following...
Environmental DNA reveals unsuspected shark diversity and calls for monitoring protection of residual populations.
Coral reefs provide ecosystem goods and services for millions of people in the tropics, but reef conditions are declining worldwide. Effective solutions to crisis facing coral depend part on understanding context under which different types conservation benefits can be maximized. Our global analysis nearly 1,800 tropical reveals how intensity human impacts surrounding seascape, measured as a function population size accessibility ("gravity"), diminishes effectiveness marine reserves at...
Delineating regions is an important first step in understanding the evolution and biogeography of faunas. However, quantitative approaches are often limited at a global scale, particularly marine realm. Reef fishes most diversified group fishes, compared to other phyla, their taxonomy geographical distributions relatively well known. Based on 169 checklists spread across all tropical oceans, present work aims quantitatively delineate biogeographical entities for reef scale. Four different...
Significance Marine organisms disperse mostly by ocean currents as larval propagules. Therefore, it is commonly thought that the duration of stage fundamental determinant geographic range size. Using a global compilation reef fish traits, we test an alternative hypothesis: adult traits associated with population establishment and persistence in novel areas are better predictors size than traits. We conclude colonization success primary successful extension among tropical fishes.
In the marine realm, tropics host an extraordinary diversity of taxa but drivers underlying global distribution organisms are still under scrutiny and we lack accurate predictive model. Using a spatial database for 6336 tropical reef fishes, attempted to predict species richness according geometric, biogeographical environmental explanatory variables. particular, aimed evaluate disentangle performances temperature, habitat area, connectivity, mid‐domain effect region on fish richness. We...

Abstract Sharks are charismatic predators that play a key role in most marine food webs. Their demonstrated vulnerability to exploitation has recently turned them into flagship species ocean conservation. Yet, the assessment and monitoring of distribution abundance such mobile environments remain challenging, often invasive resource-intensive. Here we pilot novel, rapid non-invasive environmental DNA (eDNA) metabarcoding approach specifically targeted infer shark presence, diversity eDNA...
The worldwide decline of coral reefs necessitates targeting management solutions that can sustain and the livelihoods people who depend on them. However, little is known about context in which different reef tools help to achieve multiple social ecological goals. Because nonlinearities likelihood achieving combined fisheries, function, biodiversity goals along a gradient human pressure, relatively small changes implemented could have substantial impacts whether these are likely be met....
Abstract The depletion of natural resources has become a major issue in many parts the world, with most accessible being at risk. In terrestrial realm, resource classically been related to accessibility through road networks. contrast, marine impact on living is often framed into Malthusian theory human density around ecosystems. Here, we develop new framework estimate global coral reefs using potential travel time from nearest settlement or market. We show that 58% are located < 30 min...
Abstract Although marine reserves represent one of the most effective management responses to human impacts, their capacity sustain same diversity species, functional roles and biomass reef fishes as wilderness areas remains questionable, in particular regions with deep long-lasting footprints. Here we show that fish top predators are significantly higher on coral reefs located at more than 20 h travel time from main market compared even oldest (38 years old), largest (17,500 ha) restrictive...
Abstract The impact of anthropogenic activity on ecosystems has highlighted the need to move beyond biogeographical delineation species richness patterns understanding vulnerability assemblages, including functional components that are linked processes they support. We developed a decision theory framework quantitatively assess global taxonomic and fish assemblages tropical reefs using combination sensitivity loss, exposure threats extent protection. Fish with high often exposed but largely...
Fishing pressure on coral reef ecosystems has been frequently linked to reductions of large fishes and fish biomass. Associated impacts overall community structure are, however, less clear. In size-structured aquatic ecosystems, fishing are commonly quantified using size spectra, which describe the distribution individual body sizes within a community. We examined spectra biomass communities at 38 US-affiliated Pacific islands that ranged in human presence from near pristine population...
Increasing speed and magnitude of global change threaten the world's biodiversity particularly coral reef fishes. A better understanding large-scale patterns processes on reefs is essential to prevent fish decline but it requires new monitoring approaches. Here, we use environmental DNA metabarcoding reconstruct well-known uncover hidden these highly diverse threatened ecosystems. We analysed 226 (eDNA) seawater samples from 100 stations in five tropical regions (Caribbean, Central Southwest...
The relationship between species and the functional diversity of assemblages is fundamental in ecology because it contains key information on redundancy, functionally redundant ecosystems are thought to be more resilient, resistant stable. However, this poorly understood undocumented for species-rich coastal marine ecosystems. Here, we used underwater visual censuses examine patterns redundancy one most diverse vertebrate assemblages, coral reef fishes New Caledonia, South Pacific. First,...
Abstract: Marine protected areas (MPAs) have been highlighted as a means toward effective conservation of coral reefs. New strategies are required to more effectively select MPA locations and increase the pace their implementation. Many criteria exist design networks, but generally, it is recommended that networks conserve diversity species selected for, among other attributes, representativeness, rarity, or endemicity. Because knowledge species’ spatial distribution remains scarce,...
