“…The extinction of Fortipecten takahashii, a characteristic species of the Tatsunokuchi fauna, took place at around 1.2 Ma, corresponding to the establishment of the modern subarctic water-mass (Nakashima, 2002). These data suggested that the present thermal gradient in mid-to high-latitudes was established during late Pliocene to early Pleistocene time.…”

Through the scientific results of IGCP Project 355, which studied Pacific gateways, the timing of onset or closure of each gateway has been defined. Some geological and paleontological events recognized in local areas took place as a result of gateway events. For instance, the appearance of siliceous biomarkers during the earliest Miocene in Sakhalin, northwestern Pacific, is coeval with the opening of Drake Passage during the earliest Miocene (23 Ma), and the invasion event of Hataiarca, an extinct Miocene bivalve, at 16.4 Ma in the Japanese Islands, is coeval with the closure of the Indonesian seaway. This closure indicates the first distinct appearance of the paleo-Kuroshio Current around the Philippine Islands. Japanese Paleogene faunas have been compiled recently from the biochronological aspect, and Miocene molluscan faunas are now divided into the subtropical Akeyo-Kunugidaira fauna (20-16.4 Ma), the tropical and/or subtropical Yatsuo-Kadonosawa fauna (16.4-15.3 Ma), the subtropical and/or warm temperate Moniwa fauna (15.3-15 Ma), the warm-temperate Older Shiobara-Yama fauna (15-11 Ma) and the mildtemperate and/or cool-temperate Younger Shiobara-Yama fauna (11-5.3 Ma). These faunas can be considered as responses to stepwise cooling stages from tropical to cool-temperate realms, respectively. Opening and closure of the Bering Strait during the Neogene was recently precisely redefined using diatom biochronology and fossil records of the bivalve Astarte. However, sea-water cooling is obvious after 6 Ma in high-latitude areas and tends to remain distinct until 2.5 Ma. The modern sub-arctic cold water-mass may have first appeared around 1 Ma as indicated by the first fossil record of the Chlamys islandica group in Hokkaido, Japan.It is important to consider that some kinds of geological events recognized in a local and/or regional area might have taken place in response to global events. In addition, the precise age determination of related geological events is very important for the consideration of the cause and effect of events.

“…Each trans‐Arctic divergence was obtained by calculating the average trans‐Arctic pairwise distance under the best‐fit model of evolution. Because there is great uncertainty in these molecular rate estimates, such as if trans‐Arctic gene flow occurred later than 3.5 Ma or if the Bering Strait opened at a much earlier date (Nakashima 2002), we always consider what rates would change our overall conclusions.…”

Nearshore fish (Pholis gunnellus) persists across the North Atlantic through multiple glacial episodes

The intertidal biota of the North Atlantic is characterized by two disjunct communities (North American and European) exposed to different climatic regimes during the Pleistocene and in the Holocene. We collect multilocus DNA sequence data from the nearshore fish Pholis gunnellus to help uncover processes determining biogeographical persistence during periodic coastal glaciations. Coalescent-based estimates from the multilocus DNA sequence data suggest that P. gunnellus persisted on both sides of the North Atlantic throughout the last two glacial maxima (> 202,000 years) with little trans-Atlantic gene flow since divergence, very little structure among populations within Europe (Phi(ST) < 0.05) and some structure within the North American coastline (Phi(ST) = 0.0-0.21). Although the ecological flexibility and high local migration of P. gunnellus could have enhanced this species' survival across the Atlantic, logistic regression did not find a significant determinant of trans-Atlantic persistence when considering 12 other North Atlantic phylogeographical studies from the literature.
