“…Asia and North America were directly connected during the entire Tertiary via the Bering Land Bridge. This connection was interrupted by the opening of the Bering Strait from Late Miocene to Pliocene (7.4 to 4.8 Ma ago; see Marincovich & al., 2002). However, given the position of the Bering Land Bridge at very high latitudes (65° today, and 70°-80° during the Tertiary; see ODSN, 1999), the presence of climatic limitations on migration of plants must be assumed.…”

With the present study we attempt to elucidate the history of the order Nymphaeales—water‐lilies and relatives—in time and space. On the basis of a dense taxon sampling that covers all genera of Cabombaceae and Nymphaeaceae and all subgenera of the genus Nymphaea, and on the basis of well‐supported phylogenetic hypotheses, we estimate divergence times in Nymphaeales. Distribution data for all species are used to reconstruct ancestral ranges and to identify possible dispersal events in the biogeographic history of Nymphaeales. Considering the fossil record for the clade as well as geologic history, a plausible historical scenario can be drawn. The assessment of extant biogeography shows that there are several centres of species diversity for Nymphaeales, i.e., northern South America, Central America, the Zambezian region of Africa and northern Australia. However, the diversification of the Nymphaeales started in the Northern Hemisphere when the northern landmasses were covered by tropical vegetation, except for the very high latitudes. The estimation of divergence times depicted two distinct radiation events, a rapid first differentiation into three major lineages during the Paleocene (Cabombaceae, Nuphar, remaining Nymphaeaceae) and the radiation of core Nymphaeaceae (Victoria, Euryale, Nymphaea incl. Ondinea) from the Late Oligocene to Middle Miocene. The second radiation probably started in the Northern Hemisphere. We hypothesize that subsequent spatial separation and southward relocation of the descendants led to the disjunct distribution of extant sister lineages in core Nymphaeaceae, e.g., Euryale‐Victoria or Nymphaea subgg. Hydrocallis and Lotos.

“…These trans-Artic Plumularioidea colonizations were probably from the Atlantic to the Pacific (Figure 3), which contradicts the prevalent eastward gene flow direction assumed for most marine taxa (e.g., Briggs & Bowen, 2013;Durham & MacNeil, 1967;Marincovich & Gladenkov, 1999;Vermeij, 1991;Vermeij, 2004) but agrees with inferred mollusk colonizations and predominant southward currents through the Bering Strait when it opened ca. 5.5-4.8 Mya (Marincovich, 2000;Marincovich, Barinov, & Oleinik, 2002).…”

We provide preliminary insights into the global phylogeographic and evolutionary patterns across species of the hydrozoan superfamily Plumularioidea (Cnidaria: Hydrozoa). We analyzed 1,114 16S sequences of 198 putative species of Plumularioidea collected worldwide. We investigated genetic connections and divergence in relation to present‐day and ancient biogeographic barriers, climate changes and oceanic circulation. Geographical distributions of most species are generally more constrained than previously assumed. Some species able to raft are dispersed widely. Human‐mediated dispersal explains some wide geographical ranges. Trans‐Atlantic genetic connections are presently unlikely for most of the tropical‐temperate species, but were probably more frequent until the Miocene–Pliocene transition, before restriction of the Tethys Sea and the Central American Seaway. Trans‐Atlantic colonizations were predominantly directed westwards through (sub)tropical waters. The Azores were colonized multiple times and through different routes, mainly from the east Atlantic, at least since the Pliocene. Extant geminate clades separated by the Isthmus of Panama have predominantly Atlantic origin. Various ancient colonizations mainly directed from the Indian Ocean to the Atlantic occurred through the Tethys Sea and around South Africa in periods of lower intensity of the Benguela upwelling. Thermal tolerance, population sizes, dispersal strategies, oceanic currents, substrate preference, and land barriers are important factors for dispersal and speciation of marine hydroids.

“…The first opening of the Bering Strait recently has been determined to have taken place at 5.5-5.4 Ma (Marincovich and Gladenkov, 1999;Marincovich et al, 2002;Gladenkov and Gladenkov, 2004). Afterwards, Pacific and Atlantic interchanges via the Bering Strait are recognized at 3.6 Ma and at 1.2-1.9 Ma (Marincovich, 2000;Marincovich et al, 2002).…”

“…Many studies have been also carried out on biotic migration across the Bering land bridge and seaways through it since Durham and MacNeil (1967) pointed out and discussed the migration of Neogene molluscan species (Hopkins, 1972;Kontrimavichus 1986, ed. ;Kafanov, 1982;Masuda, 1986;Marincovich et al, 1990;Vermeij, 1991Vermeij, , 2001Basilyian et al, 1993;Marincovich and Gladenkov, 1999;Marincovich et al, 2002).…”

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.
