Possible extinction event
What geographical regions were involved in the Terminal Tethyan Event according to the text?
West tethys & east tethys
How do reefs contribute to speciation rates and resistance to extinction according to the text?
Reefs increase both speciation rates and resistance to extinction.
Which of the following is NOT listed as part of the Global reef fish diversity patterns according to the text?
Anti-Tropicality
What role did the Indo-Pacific & east pacific/atlantic vicariance play according to the text?
It was a factor in the Modern Red Sea - Indian Ocean branch formation.
What event is associated with a global drop in sea levels and increased salinity in the Mediterranean Sea?
Mediterranean Messinian Salinity Crisis
Which event resulted in the division and decimation of marine species?
Pliocene-Pleistocene extinctions
What is one of the key factors that explains modern biodiversity patterns in marine environments?

12-18 million years ago
Which group of marine species experienced vicariance due to the Terminal Tethyan Event?
Angelfishes (Pomacanthidae)
Which event contributed to limited colonization in the East Pacific and extinction in the same region?
Modern Red Sea - Indian Ocean branch
What is the main characteristic of an IA hotspot according to the text?
Center of accumulation where species come from outside and accumulate in the middle
What does the text suggest about the last hopping hotspot?
It was associated with a prolonged extinction event
In the context of reef fish origins, what is the purpose of age estimation using MCMC Bayes I in the BEAST package?
To estimate the age of specific taxa based on calibrated fossils and biogeography
Which question aims to establish if there is temporal concordance in reef fish origins?
Q1 - When - Is there temporal concordance in reef fish origins?
What relationship does the text suggest between reef use and diversification rates?
% reef vs rate of diversification (reefs as drivers) = C’oOrigin
What is the significance of DNA for reef fish families according to the text?
To establish if there are periods of elevated diversification
Test your knowledge on historical biogeography concepts including center of origins, accumulation, and survival. Explore topics like possible extinction events, expansion of reef taxa during the Miocene era, and the impact of reefs on speciation rates and resistance to extinction.
