“…[ 90 – 94 ]) and, more recently, molecular phylogenetic studies of various taxa have provided certain evidence for this possibility (e.g. [ 28 , 39 , 41 – 43 , 95 ]). We estimated the ancestral regional state at each branch that splits into Japanese and continental lineages, but our results were not necessarily clear.…”

Phylogeography of freshwater planorbid snails reveals diversification patterns in Eurasian continental islands

BackgroundIslands have traditionally been the centre of evolutionary biological research, but the dynamics of immigration and differentiation at continental islands have not been well studied. Therefore, we focused on the Japanese archipelago, the continental islands located at the eastern end of the Eurasian continent. While the Japanese archipelago is characterised by high biodiversity and rich freshwater habitats, the origin and formation mechanisms of its freshwater organisms are not clear. In order to clarify the history of the planorbid gastropod fauna, we conducted phylogenetic analysis, divergence time estimation, ancestral state reconstruction, and lineage diversity estimations.ResultsOur analyses revealed the formation process of the planorbid fauna in the Japanese archipelago. Most lineages in the Japanese archipelago have closely related lineages on the continent, and the divergence within the Japanese lineages presumably occurred after the late Pliocene. In addition, each lineage is characterised by different phylogeographical patterns, suggesting that immigration routes from the continent to the Japanese archipelago differ among lineages. Furthermore, a regional lineage diversity plot showed that the present diversity in the Japanese archipelago potentially reflects the differentiation of lineages within the islands after the development of the Japanese archipelago.ConclusionsAlthough additional taxon sampling and genetic analysis focused on each lineage are needed, our results suggest that immigration from multiple routes just prior to the development of the Japanese archipelago and subsequent diversification within the islands are major causes of the present-day diversity of the Japanese planorbid fauna.Electronic supplementary materialThe online version of this article (10.1186/s12862-018-1273-3) contains supplementary material, which is available to authorized users.

“…This archipelago and its complex geography are an attractive model system for biogeographical studies, and a lot of research using molecular data has been published in recent years (e.g. [ 16 , 35 – 43 ]). However, fewer biogeographical studies have been conducted using freshwater organisms in the Japanese archipelago.…”

“…The Fossa Magna was later filled with thick sediments from the Tertiary (Takeda et al, 2004), and the subsequent elevation of the surrounding land during the Quaternary led to the formation of the high mountain chains in central Honshu. The Fossa Magna and orogenic movements are considered important dispersal barriers for many animal species; recent molecular phylogeographical analyses have indicated deep divergences between inter-and intraspecific vicariants in the Fossa Magna region (Sekiné, Hayashi, & Tojo, 2013;Shoda-Kagaya et al, 2010;Suzuki, Sato, & Ohba, 2002;Tojo et al, 2017;Watanabe et al, 2006;Watanabe, Tominaga, Nakajima, Kakioka, & Tabata, 2017). Furthermore, glacial and interglacial cycles have also been considered to affect genetic structures, mainly through the expansion and contraction of organismal distributions and through migrations from the Asian continent across land bridges during the Quaternary (Millien-Parra & Jaeger, 1999;Motokawa, 2017;Qiu, Fu, & Comes, 2011).…”

“…Approximately 15 million years ago (Mya), two landmasses—the northeastern and southwestern portions of the Proto‐Japanese Islands—began to independently separate from the Asian continent, along with the formation of the Sea of Japan. Before the two landmasses were connected to each other, eastern and western Japan were separated by a sea zone (channel) called the Fossa Magna, which longitudinally traversed central Honshu, Japan (area in gray; Figure ), during the Miocene (around 15–5 Mya; Tojo, Sekiné, Suzuki, Saito, & Takenaka, ). The Fossa Magna was later filled with thick sediments from the Tertiary (Takeda et al, ), and the subsequent elevation of the surrounding land during the Quaternary led to the formation of the high mountain chains in central Honshu.…”

Nuclear microsatellite and mitochondrial DNA analyses reveal the regional genetic structure and phylogeographical history of a sanguivorous land leech, Haemadipsa japonica, in Japan

Recent molecular studies have indicated that phylogeographical history of Japanese biota is likely shaped by geohistory along with biological events, such as distribution shifts, isolation, and divergence of populations. However, the genetic structure and phylogeographical history of terrestrial Annelida species, including leech species, are poorly understood. Therefore, we aimed to understand the genetic structure and phylogeographical history across the natural range of Haemadipsa japonica , a sanguivorous land leech species endemic to Japan, by using nine polymorphic nuclear microsatellites (nSSR) and cytochrome oxidase subunit one (COI) sequences of mitochondrial DNA (mtDNA). Analyses using nSSR revealed that H . japonica exhibited a stronger regional genetic differentiation among populations ( G ' ST = 0.77) than other animal species, probably because of the low mobility of land leech. Analyses using mtDNA indicated that H . japonica exhibited two distinct lineages (A and B), which were estimated to have diverged in the middle Pleistocene and probably because of range fragmentation resulting from climatic change and glacial and interglacial cycles. Lineage A was widely distributed across Japan, and lineage B was found in southwestern Japan. Analyses using nSSR revealed that lineage A was roughly divided into two population groups (i.e., northeastern and southwestern Japan); these analyses also revealed a gradual decrease in genetic diversity with increasing latitude in lineage A and a strong genetic drift in populations of northeastern Japan. Combined with the largely unresolved shallow polytomies from the mtDNA phylogeny, these results implied that lineage A may have undergone a rapid northward migration, probably during the Holocene. Then, the regional genetic structure with local unique gene pools may have been formed within each lineage because of the low mobility of this leech species.

“…japonicus , and especially in that we consider that our results of both the nDNA and mtDNA data sets are robust. Although, it has been considered that almost all the Japanese organisms were dispersed from the Eurasian Continent via land bridges, recent studies suggest that back dispersal is also one of the significant characteristics of the Japanese biodiversity (Suzuki et al, 2014; Tojo, Sekiné, Suzuki, et al, 2017; Tojo, Sekiné, Takenaka, et al, 2017; Ikeda et al, 2020). Moreover, because nDNA is affected by genetic exchanges, it is difficult to estimate the evolutionary history of organisms which are derived from hybridization between intraspecific genetically differentiated clades over the past few million years, if using the nDNA data set only.…”
