Marine incursion into East Asia: a forgotten driving force of biodiversity.

چکیده
Episodic marine incursion has been a major driving force in the formation of present-day diversity. Marine incursion is considered to be one of the most productive 'species pumps' particularly because of its division and coalescence effects. Marine incursion events and their impacts on diversity are well documented from South America, North America and Africa; however, their history and impacts in continental East Asia largely remain unknown. Here, we propose a marine incursion scenario occurring in East Asia during the Miocene epoch, 10-17 Ma. Our molecular phylogenetic analysis of Platorchestia talitrids revealed that continental terrestrial populations (Platorchestia japonica) form a monophyletic group that is the sister group to the Northwest Pacific coastal species Platorchestia pacifica. The divergence time between the two species coincides with Middle Miocene high global sea levels. We suggest that the inland form arose as a consequence of a marine incursion event. This is the first solid case documenting the impact of marine incursion on extant biodiversity in continental East Asia. We believe that such incursion event has had major impacts on other organisms and has played an important role in the formation of biodiversity patterns in the region.

A Mapping of Marine Biodiversity Research Trends and Collaboration in the East Asia Region from 1996–2015
Many countries define policies to manage oceans and coastal areas in order to utilize marine ecosystems strategically. When we reviewed the strategies and policies of various countries in relation to ocean sustainability, we found that biodiversity preservation is a key issue for policies related to sustainable marine development. We investigated the research trends and collaboration status of ...
متن کاملMarine Incursion: The Freshwater Herring of Lake Tanganyika Are the Product of a Marine Invasion into West Africa
The spectacular marine-like diversity of the endemic fauna of Lake Tanganyika, the oldest of the African Great Lakes, led early researchers to suggest that the lake must have once been connected to the ocean. Recent geophysical reconstructions clearly indicate that Lake Tanganyika formed by rifting in the African subcontinent and was never directly linked to the sea. Although the Lake has a hig...

The demand for live seafood in Asia has spawned a lucrative trade in live coral reef fish that in 1995 had a global annual retail value of over USD 1 billion (Johannes and Riepen 1995; Cesar et al. 1997). There are concerns that the live reef fish food trade is inflicting an unacceptably heavy impact on coral reefs and reef resources in Southeast Asia and the Indo-Pacific.5 These areas contain ...
