How do biogeographically different provinces arise in response to oceanic barriers to dispersal? Here, we analyse how traits related to the pelagic dispersal and adult biology of 985 tropical reef fish species correlate with their establishing populations on both sides of two Atlantic marine barriers: the Mid-Atlantic Barrier (MAB) and the Amazon-Orinoco(More)
The invasion of the northwestern Atlantic by the Indo-Pacific lionfish has developed extraordinarily fast, and is expected to cause one of the most negative ecological impacts among all marine invasions. In less than 30 years, lionfish have dramatically expanded their distribution range to an area encompassing the eastern coast of the USA, Bermuda, the(More)
Ecological communities that occupy similar habitats may exhibit functional convergence despite significant geographical distances and taxonomic dissimilarity. On coral reefs, steep gradients in key environmental variables (e.g. light and wave energy) restrict some species to shallow depths. We show that depth-generalist reef fishes are correlated with two(More)
Trait-based approaches advance ecological and evolutionary research because traits provide a strong link to an organism's function and fitness. Trait-based research might lead to a deeper understanding of the functions of, and services provided by, ecosystems, thereby improving management, which is vital in the current era of rapid environmental change.(More)
Most marine organisms disperse via ocean currents as larvae, so it is often assumed that larval-stage duration is the primary determinant of geographic range size. However, empirical tests of this relationship have yielded mixed results, and alternative hypotheses have rarely been considered. Here we assess the relative influence of adult and larval-traits(More)
In the last decades, a number of studies based on historical records revealed the diversity loss in the oceans and human-induced changes to marine ecosystems. These studies have improved our understanding of the human impacts in the oceans. They also drew attention to the shifting baseline syndrome and the importance of assessing appropriate sources of data(More)
We examine divers' changes in marine life preferences and perceptions. Novice divers preferred megafauna and experienced divers, cryptic animals. Perceptions of decreasing in the quality of fish attributes were accompanied by the worst expectations. Experience and perceptions can be used as a predictor to maximizing diver's enjoyment. We provide managerial(More)
Reef fishes have two major spawning strategies: pelagicspawning, in which buoyant eggs and sperm are shed directly into the water column, and demersal-spawning, in which adhesive eggs are placed on the bottom and usually are guarded by one or both parents until hatching into planktonic larvae (Thresher, 1984). Pelagic spawning species may either spawn in(More)
The occurrence of the Brazilian endemic parrotfish Sparisoma frondosum is confirmed for the Cape Verde Archipelago, in the Tropical Eastern Atlantic. In total, 12 species of reef fishes previously thought to be either endemic or originated in the Brazilian Province have been recently recorded as vagrants in the southern Caribbean and in West African(More)
