“…In Figure , the “araneus” group is placed as a well‐supported sister branch to S. samniticus , and the relationships within the former clade (Supporting Information Figure ) are the same as in previous studies (Bannikova & Lebedev, ; Fumagalli et al., ; Mackiewicz et al., ). The species of the “caecutiens” group do not form a clade; however, S. caecutiens clusters robustly with S .…”

“…Previously, it was found that the expected scenario of chromosome evolution is incompatible with mitochondrial and allozyme patterns (Basset, Yannic, & Hausser, ; Catzeflis et al., ; Ruedi, ; Taberlet et al., ). In particular, karyotype‐based reconstructions recover S. granarius as the basal branch within “araneus” (Mackiewicz et al., ; Taberlet et al., ; Volobouev & Dutrillaux, ), while mtDNA and allozyme data (Ruedi, ) suggest that it is genealogically very close to S. araneus .…”

“…The mitochondrial phylogeny of Sorex was examined in several studies using the cytochrome b gene ( cytb ) (Fumagalli et al., ; Mackiewicz, Moska, Wierzbicki, Gagat, & Mackiewicz, ; Ohdachi et al., , ); however, many nodes in the mitochondrial tree remained unresolved. The branching pattern inferred in the combined analysis of two mitochondrial and two nuclear genes (Dubey et al., ) was poorly supported as well, thus suggesting that adequate resolution can be obtained only with sufficiently large multilocus data.…”

Evolutionary history of the genus Sorex (Soricidae, Eulipotyphla) as inferred from multigene data

The genus Sorex is one of the most diverse and ecologically successful lineages of the family Soricidae. We present the first multilocus nuclear phylogeny focusing on the nominal subgenus Sorex s.str., which is distributed mainly in the northern Palearctic. The nuclear tree (six exons) provides more resolution than the mitochondrial data (cytb) and supports subdivision into eight species groups within Sorex s.str., most of which correspond to those recognized from chromosome data. The European species S. alpinus is consistently placed as the basal lineage in the Palearctic clade, while the next split separates the east‐Tibetan group of striped shrews (S. aff. cylindricauda, S. bedfordiae, S. excelsus). Within the remaining species, the following well‐supported clades are identified at the supra‐group level: “araneus” species group+S. samniticus; the “caecutiens” group+the “minutus” group, the latter also including S. minutissimus, S. gracillimus and S. thibetanus. S. raddei and S. roboratus represent separate lineages with no close relatives. The fossil‐calibrated molecular clock placed the divergence between Sorex s.str. and Otisorex at the Early/Middle Miocene boundary. Basal radiation of the crown Sorex s.str. was estimated to have occurred in the middle of the Late Miocene. A more than threefold increase in the diversification rate is inferred for the Early Pliocene. Taxonomic implications including potential genus ranks for Sorex s.str. and Otisorex are discussed. S. alpinus is placed in the monotypic subgenus Homalurus. The full species status of S. buchariensis and S. thibetanus and close relationships between S. cf. cansulus and S. caecutiens are confirmed.

“…Our topology (see Figure ) was consistent with previous phylogenetic studies based on mtDNA, in which it has been suggested that S. granarius is closely related to S. araneus (Fumagalli, Hausser, Taberlet, Gielly, & Stewart, ; Taberlet, Fumagalli, & Hausser, ; Yannic, Basset, & Hausser, ,b). However, studies based on Y‐chromosomes and karyotypic data have argued that S. granarius occupies a basal position and should be considered the common ancestor of all species of the S. araneus complex (Yannic, Dubey, Hausser, & Basset, ; Mackiewicz, Moska, Wierzbicki, Gagat, & Mackiewicz, ). This phylogenetic inconsistency has been attributed to past mtDNA introgression from S. araneus to S. granarius (Yannic et al.…”

There are examples of coexisting species with similar morphology and ecology, in apparent contradiction to competition theory. Shrews (Soricidae) are a paradigmatic example of this because members of this group exhibit a conserved body form, relatively low variability in lifestyle, and, in many cases, a sympatric distribution. Here, we combined geometric morphometrics and ecological niche modeling to test whether diversification of soricid species inhabiting the Iberian Peninsula has been driven by niche divergence or, conversely, whether niche conservatism has played a paramount role in this process. We also examined whether pairwise morphological distances increase as the degree of niche overlap between species becomes greater, as would be expected if interspecific competition promotes morphological differentiation. Our results showed that water shrews (Neomys), white‐toothed shrews (Crocidurinae), and red‐toothed shrews (Soricinae) are clearly differentiated in terms of both skull shape and mandible shape. However, we found a lack of phylogenetic signal in most morphological traits, indicating that closely related species are not more similar than expected by random chance. Notably, water shrews show a more “triangular” or sharp skull than white‐toothed and red‐toothed shrews, probably as an adaptation to their semiaquatic lifestyle. In agreement with the phenotypic data, climatic traits (mean annual temperature and annual precipitation) were highly labile and sister taxa showed extensive differentiation in their realized niche space. Finally, we found that phenotypic distances between species tend to increase as the degree of niche overlap increases, suggesting that interspecific competition is an important factor in determining the level of morphological resemblance among relatives. Overall, our results indicate that the existence of limited morphological disparity in a given group does not necessarily imply the existence of a niche conservatism signature.

Far away from home? Ancient DNA shows the presence of bicolored shrew (Crocidura leucodon) in Bronze Age Denmark

An excavation of an Early Iron Age village near Aalborg in Denmark uncovered the jaws and skull fragments from a small mammal that were morphologically identified to the genus Crocidura (white‐toothed shrews). Three Crocidura species are known from prehistoric continental Europe but none of them are distributed in Scandinavia, which is why this surprising finding warranted further analyses. The bone was radiocarbon‐dated to 2840–2750 calibrated years before present (cal. BP), corresponding to the Late Bronze Age and hence earlier than the Iron Age archeological context in which it was found. Using highly optimized ancient DNA protocols, we extracted DNA from one tooth and shotgun‐sequenced the sample to reconstruct a near‐complete mitochondrial reference genome (17,317 bp, 32.6× coverage). Phylogenetic analyses determined this specimen as a bicolored shrew (Crocidura leucodon) but with a phylogenetic position basal to the clade of known sequences from this species. The confirmation of Crocidura presence in Denmark by the Late Bronze Age sheds new light on the prehistoric natural history of Scandinavia. We discuss the implications of this finding from both zoo‐archeological and ecological perspectives. Furthermore, the mitochondrial genome reconstructed in this study offers a valuable resource for future research exploring the genetic makeup and evolutionary history of Eurasian shrew populations.
