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...
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...
Coral reefs are diverse ecosystems that support millions of people worldwide by providing coastal protection from waves. Climate change and human impacts leading to degraded coral rising sea levels, posing concerns for the tropical regions in near future. We use a wave dissipation model calibrated with empirical data calculate future increase back-reef height. show that, future, structural complexity is more important than sea-level rise determining provided average also significant heights...
Little fish make a big contribution Coral reefs represent one of the most biodiverse and rich ecosystems. Such richness conjures up images coral heads large colorful reef fishes. Brandl et al. show, however, that striking important parts ecosystem is almost never seen (see Perspective by Riginos Leis). Small cryptobenthic fish, like blennies, nearly 40% biodiversity. Furthermore, majority larvae settle locally, rather than being widely dispersed, have rapid turnover rates. high diversity...
The most prominent pattern in global marine biogeography is the biodiversity peak Indo-Australian Archipelago. Yet processes that underpin this are still actively debated. By reconstructing paleoenvironments over past 3 million years on basis of sediment cores, we assessed extent to which Quaternary climate fluctuations can explain variation current reef fish richness. Comparing historical coral habitat availability with present-day distribution 6316 species, find distance from stable...
Abstract The Cretaceous breakup of Gondwana strongly modified the global distribution shallow tropical seas reshaping geographic configuration marine basins. However, links between reef availability, plate tectonic processes and biodiversity patterns are still unknown. Here, we show that a spatial diversification model constrained by absolute motions for past 140 million years predicts emergence movement diversity hotspots on reefs. dynamics reefs explains fauna in Tethyan Ocean during early...
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 Climatic niche conservatism, the tendency of species‐climate associations to remain unchanged across space and time, is pivotal for forecasting spread invasive species biodiversity changes. Indeed, it represents one key assumptions underlying distribution models ( SDM s), main tool currently available predicting range shifts species. However, date, no comprehensive assessment conservatism marine realm. We use invasion by Indo‐Pacific tropical fishes into Mediterranean Sea, world's...
Coral bleaching events threaten coral reef habitats globally and cause severe declines of local biodiversity productivity. Related to high sea surface temperatures (SST), are expected increase as a consequence future global warming. However, response climate change is still uncertain low-latitude climatic conditions have no present-day analogue. Sea during the Eocene epoch were warmer than forecasted changes for coming century, distributions corals may help inform models forecasting reefs....
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...
Understanding the effects of environmental change on ecosystems requires identification baselines that may act as reference conditions. However, continuous these references challenges our ability to define true natural status ecosystems. The so-called sliding baseline syndrome can be overcome through analysis quantitative time series, which are, however, extremely rare. Here we show how combining historical data with descriptive 'naturalistic' information arranged in a chronological chain...
Abstract Anthropogenic stressors have strong impacts on ecosystems. To understand their influence, detailed knowledge about trophic relationships among species is critical. However, this requires both exceptional resolution in dietary assessments and sampling breadth within communities, especially for highly diverse, tropical We used gut content metabarcoding across a broad range of coral reef fishes (8 families, 22 species) Mo'orea, French Polynesia, to test whether technique has the...
Alien species are considered one of the prime threats to biodiversity, driving major changes in ecosystem structure and function. Identifying traits associated with alien introduction has been largely restricted comparing indigenous or that differ abundance impact. However, a more complete understanding may emerge when entire pool potential is used as control, information rarely available. In eastern Mediterranean, marine environment undergoing an unparalleled composition transformation,...
Abstract Although coral reefs support the largest concentrations of marine biodiversity worldwide, extent to which global system marine-protected areas (MPAs) represents individual species and breadth evolutionary history across Tree Life has never been quantified. Here we show that only 5.7% scleractinian 21.7% labrid fish reach minimum protection target 10% their geographic ranges within MPAs. We also estimate current MPA secures 1.7% for corals, 17.6% fishes. Regionally, Atlantic Eastern...
Taxonomic nestedness, the degree to which taxonomic composition of species‐poor assemblages represents a subset richer sites, commonly occurs in habitat fragments and islands differing size isolation from source pool. However, species are not ecologically equivalent extent nestedness is observed terms functional trait still remains poorly known. Here, using an extensive database on traits distributions 6316 tropical reef fish across 169 we assessed levels taxonomical vs at global scale....
Understanding species' roles in food webs requires an accurate assessment of their trophic niche. However, it is challenging to delineate potential interactions across ecosystem, and a paucity empirical information often leads inconsistent definitions guilds based on expert opinion, especially when applied hyperdiverse ecosystems. Using coral reef fishes as model group, we show that experts disagree the assignment broad for more than 20% species, which hampers comparability studies. Here,...
