Sharks occupy marine habitats ranging from shallow, inshore environments to pelagic, and deepwaters, and thus provide a model system for testing how gross habitat differences have shaped vertebrate macroevolution. Palaeontological studies have shown that onshore lineages diversify more quickly than offshore taxa. Among onshore habitats, coral reef‐association has been shown to increase speciation rates in several groups of fishes and invertebrates. In this study, we investigated whether… 

Non-reef environments impact the diversification of extant jacks, remoras and allies (Carangoidei, Percomorpha)

Through the ecological radiation of carangoid fishes, it is demonstrated that non-reef environments may sustain and promote processes of diversification of different marine fish groups, at least those including a large proportion of piscivorous species.

Feeding ecology has shaped the evolution of modern sharks

Evolutionary bottlenecks in brackish water habitats drive the colonization of fresh water by stingrays

It is revealed that vicariant processes most likely caused freshwater transition during the time of major marine incursions, and habitat transition rates indicate that brackish water species switch preferably back into marine than forth into freshwater habitats.

Phylogenetic perspectives on reef fish functional traits

It is argued that the combination of a phylogenetic and a functional approach will improve the understanding of the mechanisms of species assembly in extraordinarily rich coral reef communities.

Global shifts in species richness have shaped carpet shark evolution

It is found that carpet sharks species richness was greatest in shallow seas connected to the Atlantic Ocean during the Late Cretaceous, but that there was a subsequent loss of biodiversity in Atlantic waters.

The importance of offshore origination revealed through ophiuroid phylogenomics

A phylogenetic approach across an entire class of marine invertebrates suggests that most of the oldest clades have a deep-sea origin, but multiple colonization events indicate that the evolution of this group conforms neither to a simple onshore–offshore hypothesis, nor the opposite pattern.

Environmental DNA reveals tropical shark diversity in contrasting levels of anthropogenic impact

It is demonstrated that eDNA metabarcoding can be effectively employed to study shark diversity and further developments in this field have the potential to drastically enhance the ability to assess and monitor elusive oceanic predators, and lead to improved conservation strategies.

Phylogenetic perspectives on reef fish functional traits: Evolution of functional traits

Functional traits have been fundamental to the evolution and diversification of entire fish lineages on coral reefs. Yet their relationship with the processes promoting speciation, extinction and the

Do habitat shifts drive diversification in teleost fishes? An example from the pufferfishes (Tetraodontidae)

Results suggest that ecological opportunity afforded by novel habitats may be limited for pufferfishes due to competition with other species, constraints relating to pufferfish life history and trophic ecology, and other factors.

DO REEFS DRIVE DIVERSIFICATION IN MARINE TELEOSTS? EVIDENCE FROM THE PUFFERFISH AND THEIR ALLIES (ORDER TETRAODONTIFORMES)

It is suggested that both intrinsic factors of reef habitat and extrinsic factors relating to the provincialization and regionalization of the marine biota during the Miocene played a role in shaping these patterns of diversity.

Reefs as Cradles of Evolution and Sources of Biodiversity in the Phanerozoic

Analysis of fossil evidence indicates that reefs were disproportionally important in the origination of new species, which might be a consequence of low-diversity habitats being more susceptible to invasions.

Iterative Ecological Radiation and Convergence during the Evolutionary History of Damselfishes (Pomacentridae)

Tests of the tempo of lineage diversification using a time-calibrated phylogeny including 208 species revealed that crown pomacentrid diversification has not slowed through time as expected under a scenario of a single adaptive radiation resulting from an early burst of diversification.

Coral reefs as drivers of cladogenesis: expanding coral reefs, cryptic extinction events, and the development of biodiversity hotspots

Patterns of diversification suggest that coral reefs acted as a refuge from high extinction, as reef taxa are able to sustain diversification at high extinction rates.

Environmental determinants of marine benthic biodiversity dynamics through Triassic–Jurassic time

The relationship between biodiversity dynamics and environments in the data set is governed by the partitioning of higher taxa within environmental categories and not directly due to greater chances of origination in particular settings, and an indirect environmental control on evolutionary rates is proposed.

Coral reefs promote the evolution of morphological diversity and ecological novelty in labrid fishes.

The results suggest that coral reef habitats promote the evolution of both trophic novelty and morphological diversity within fishes, and the preservation of coral reefs is necessary to safeguard current biological diversity but also to conserve the underlying mechanisms that can produce functional diversity in future.

Evolution of corallivory in the gastropod genus Drupella

This work uses a well resolved molecular phylogeny to show that the monophyletic genus Drupella falls into the muricid subfamily Ergalataxinae and that the genus includes ‘E. margariticola’, which is composed of two cryptic species, and suggests that corallivory in Drupeella evolved in response to the major expansion and reorganization of reefs that took place in the early Miocene.
