The origins of tropical marine biodiversity
TLDR
Biodiversity hotspots such as the Caribbean Sea and the Indo-Pacific Coral Triangle produce and export species, but can also accumulate biodiversity produced in peripheral habitats, which benefits both hotspots and peripheral ecosystems in a process dubbed biodiversity feedback.Abstract:
Recent phylogeographic studies have overturned three paradigms for the origins of marine biodiversity. (i) Physical (allopatric) isolation is not the sole avenue for marine speciation: many species diverge along ecological boundaries. (ii) Peripheral habitats such as oceanic archipelagos are not evolutionary graveyards: these regions can export biodiversity. (iii) Speciation in marine and terrestrial ecosystems follow similar processes but are not the same: opportunities for allopatric isolation are fewer in the oceans, leaving greater opportunity for speciation along ecological boundaries. Biodiversity hotspots such as the Caribbean Sea and the Indo-Pacific Coral Triangle produce and export species, but can also accumulate biodiversity produced in peripheral habitats. Both hotspots and peripheral ecosystems benefit from this exchange in a process dubbed biodiversity feedback.read more

Surviving in a Marine Desert: The Sponge Loop Retains Resources Within Coral Reefs
Jasper M. de Goeij,Dick van Oevelen,Mark J. A. Vermeij,Ronald Osinga,Jack J. Middelburg,Anton F.P.M. de Goeij,Wim Admiraal +6 more
TL;DR: The DOM-sponge-fauna pathway explains why biological hot spots such as coral reefs persist in oligotrophic seas—the reef’s paradox—and has implications for reef ecosystem functioning and conservation strategies.

Why are there so many species in the tropics
TL;DR: Accumulating theoretical and empirical studies suggest that the single most important factor is kinetics: the temperature dependence of ecological and evolutionary rates.

TL;DR: The figures suggest that the conservation status of South American freshwater fish faunas is better than in most other regions of the world, but the marine fishes are as threatened as elsewhere.

Biodiversity hotspots: A shortcut for a more complicated concept
TL;DR: The area-based approach can be applied to any geographical scale and it is considered to be one of the best approaches for maintaining a large proportion of the world's biological diversity as discussed by the authors.

Marine Biodiversity, Biogeography, Deep-Sea Gradients, and Conservation.
TL;DR: How many marine species are named and estimated to exist is assessed, paying particular regard to whether discoveries of deep-sea organisms, microbes and parasites will change the proportion of terrestrial to marine species.
