“…To date, 76 chromosomal races have been described (Bulatova et al, 2019), which have been combined into several karyotypic groups. These groups partly match the phylogeographic groups revealed by analyses of mitochondrial gene cytb (Thaw et al, 2019). Both the karyotypic and phylogenetic diversification of groups were affected by Late Pleistocene and Holocene climatic events (Thaw et al, 2019;White et al, 2019).…”

Both the karyotypic and phylogenetic diversification of groups were affected by Late Pleistocene and Holocene climatic events (Thaw et al, 2019;White et al, 2019). On the other hand, morphometric analyses of geographic samples have yielded inconsistent results, i.e., in several articles, morphometric variation usually contradicts individual race boundaries (Searle and Thorpe, 1987;Wójcik et al, 2000;Banaszek et al, 2003;Mishta, 2007), but in several reports, the morphometric variation correlates with karyotypic group compound (Chętnicki et al, 1996;Polyakov et al, 2002).…”

“…The common shrew is the most popular research subject in different aspects of evolutionary biology, adaptation, and speciation (see reviews by several authors, e.g., Polly, 2019;Thaw et al, 2019;Taylor et al, 2022) just as the house mouse model (Zima and Searl, 2019). Intensive investigations in the last three decades have revealed high levels of pheno-typic and genotypic polymorphisms among recent samples of the common shrew (Searle and Wójcik, 1998;Polly, , 2005Polly, , 2007Wójcik et al, 2003;Mishta and Searle, 2019;White et al, 2019;Zima and Searl, 2019).…”

Several patterns were revealed in a temporal study on morphological variety of Sorex araneus and S. tundrensis (Soricidae, Mammalia). We examined samples from 18 modern and three fossil Early-Late Holocene Uralian localities. We analyzed shape variation of the first lower molar and hemimandible using two-dimensional geometrical landmarks; size differences were estimated by means of three linear measures. A separate purpose was estimation of the measurement error that arose during the data acquisition. We found that the modern samples of both species share underestimated similarity in both size and shape of morphological structures. Regression analysis revealed different phenotypic traits of the mandibular proportion in the large and small shrews regardless of species attribution. A size decrease of S. araneus and conversely a size increase of S. tundrensis both drive the mandibular shape toward phenotypic convergence. This pattern, however, is violated in the fossil samples, where the largest S. tundrensis from a Late Holocene Sim III locality (South Ural) showed a well-distinguishable mandibular shape located in a separate part of the morphospace. In this work, we found that the m1 shape has only weak resolving power as compared to the mandibular or especially skull shape. Nonetheless, even the moderate resolving power of the mandibular shape allowed us to uncover phenotypic changes during the Holocene that have not been noticed by previous researchers at Uralian late Quaternary localities.

“…Given its current restriction there, it can be suggested that S. granarius was localised in Iberia throughout the Last Glaciation. S. araneus is believed to have had a glacial refugium in southeastern Europe and spread widely eastwards, westwards, and northwards in the warmer conditions after the Last Glacial Maximum (LGM) [ 26 ], and presumably reached southwestern Europe at that time. It is difficult to be exactly sure of the ranges of S. araneus , S. coronatus , and S. granarius during the Late Glacial period from the end of the LGM until the beginning of the Holocene—comprising the time interval of approximately 20–10,000 years ago, incorporating the Bølling–Allerød warm period followed by the Younger Dryas cold period [ 25 ].…”

Mitochondrial introgression raises questions of biogeography and of the extent of reproductive isolation and natural selection. Previous phylogenetic work on the Sorex araneus complex revealed apparent mitonuclear discordance in Iberian shrews, indicating past hybridisation of Sorex granarius and the Carlit chromosomal race of S. araneus, enabling introgression of the S. araneus mitochondrial genome into S. granarius. To further study this, we genetically typed 61 Sorex araneus/coronatus/granarius from localities in Portugal, Spain, France, and Andorra at mitochondrial, autosomal, and sex-linked loci and combined our data with the previously published sequences. Our data are consistent with earlier data indicating that S. coronatus and S. granarius are the most closely related of the three species, confirming that S. granarius from the Central System mountain range in Spain captured the mitochondrial genome from a population of S. araneus. This mitochondrial capture event can be explained by invoking a biogeographical scenario whereby S. araneus was in contact with S. granarius during the Younger Dryas in central Iberia, despite the two species currently having disjunct distributions. We discuss whether selection favoured S. granarius with an introgressed mitochondrial genome. Our data also suggest recent hybridisation and introgression between S. coronatus and S. granarius, as well as between S. araneus and S. coronatus.

“…Phylogeographical studies utilizing genetic markers having phylogenetic signals such as cpDNAs and nrITS and analyzing the spatial distribution of haplotypes across species or species complex ranges, allow for verifying taxonomy at various taxonomic levels. Besides, such studies can unravel historical processes that led to the formation of species or affected their distribution (e.g., post-glacial migrations) and identify potential glacial refugia (Avise, 2000 , 2004 ; Thaw et al, 2019 ). Refugia, i.e., locations where species have persisted during long-term climatic changes due to their eco-climatic stability, have high conservation value, so it is very important to identify precise refugial locations (Médail and Diadema, 2009 ; Hampe et al, 2013 ; Volis, 2019 ).…”

Phylogeography and Population Genetics of Rosa chinensis var. spontanea and R. lucidissima Complex, the Important Ancestor of Modern Roses

et al. 2022

Rosa chinensis var. spontanea and R. lucidissima complex are the morphologically very similar key ancestors of modern roses with high importance in rose research and breeding. Although widely distributed in subtropical central and southwestern China, these two taxa are highly endangered. We sampled a total of 221 specimens and 330 DNA samples from 25 populations across the two taxa's whole range. Leaf morphological traits were compared. Two chloroplast DNA intergenic spacers (trnG-trnS, petL-psbE) and ITS were used for population genetics and phylogenetic study to delimit the boundary between the two taxa, assess the genetic variation, uncover the possible evolutionary mechanism responsible for the differentiation within the complex, and make the conservation recommendations. The complex exhibited high levels of genetic variation (hTcpDNA = 0.768, hTITS = 0.726) and high population differentiation even over small geographic distance. We suggest R. chinensis var. spontanea and R. lucidissma be treated as independent taxa, and the northern populations around and within the Sichuan Basin being R. chinensis var. spontanea, having broader leaflets and paler full-blooming flowers, while those in the middle and southern Yunnan-Guizhou Plateau and the adjacent regions being R. lucidissma, having narrower leaflets and darker full-blooming flowers. Transitional areas between the southeastern Sichuan Basin and northeastern Guizhou are the contact or the hybridization zone of the two taxa. Ancestral haplotypes of the complex (R. lucidissma) evolved at about 1.21–0.86 Mya in southeastern Yunnan-Guizhou Plateau and its adjacent regions and survived there during the Quaternary Oscillation. Ancestral haplotypes of R. chinensis var. spontanea deviated from R. lucidissma at about 0.022–0.031 Mya at the transitional areas (Daloushan and Wulingshan Mountains) between the northeastern edge of Yunnan-Guizhou Plaeteau and the southeastern border of Sichuan Basin, where they survived the LGM. The evolution of the complex included spatial isolation and inter-species hybridization. The complex's endangered status might be the result of over-exploitation for its ornamental and medical value, or due to reforestation of some originally open habitats. We provide specific recommendations for the two taxa's in situ and ex situ conservation.
