“…As already documented in all reconstructions based on distinct mitochondrial genes (e.g., Ibáñez et al 2006, Mayer et al 2007, Evin et al 2011, Veith et al 2011, Çoraman et al 2013, sequences issued from this species complex form more or less wellseparated clades, but relationships among them lack resolution, which is fully consistent with the reconstructions presented in Figure 7.…”

Pipistrellus deserti is a small, pale-coloured bat occurring in the most arid parts of the Sahara, in Morocco, Algeria, Libya, Egypt, and the Sudan, and marginally also in sub-Saharan Africa. Although most authors consider P. deserti as a full species, others regard it as a subspecies, or even as a junior synonym of Pipistrellus kuhlii. We analysed the topotype material of P. deserti from Libya using both morphologic and molecular characters, and compared them with samples from other Saharan countries and with P. kuhlii from around the Mediterranean. The Libyan samples of deserti are morphologically very similar to other populations from arid parts of North Africa (Morocco, Algeria, Egypt, Sudan), but differ markedly in the size of most skull dimensions when compared to P. kuhlii sampled in more mesic areas. However, phylogenetic reconstructions indicate that mitochondrial haplotypes of typical P. deserti from Libya and those from Morocco do not form a monophyletic group but are fully embedded within the larger radiation of P. kuhlii from Africa and Europe, rendering this species paraphyletic. Limited nuclear information (five microsatellite loci) also failed to provide evidence of significant differences between the two morphotypes, as pipistrelles are instead grouped by geographic origin. Altogether, these genetic data suggest that the morphological uniqueness of P. deserti may result from recent adaptations to arid habitats, rather than reflect a long independent evolutionary history. In the absence of more compelling evidence of barriers to gene flow, we therefore suggest Pipistrellus deserti to be considered a junior synonym of Vespertilio kuhlii ( = P. kuhlii).

Two Mitochondrial Barcodes for one Biological Species: The Case of European Kuhl's Pipistrelles (Chiroptera)

The Kuhl’s pipistrelle (Pipistrellus kuhlii) is a Western Palaearctic species of bat that exhibits several deeply divergent mitochondrial lineages across its range. These lineages could represent cryptic species or merely ancient polymorphism, but no nuclear markers have been studied so far to properly assess the taxonomic status of these lineages. We examined here two lineages occurring in Western Europe, and used both mitochondrial and nuclear markers to measure degrees of genetic isolation between bats carrying them. The sampling focused on an area of strict lineage sympatry in Switzerland but also included bats from further south, in North Africa. All individuals were barcoded for the COI gene to identify their mitochondrial lineages and five highly polymorphic microsatellite loci were used to cluster them according to their nuclear genotypes. Despite this low number of nuclear markers, all North African nuclear genotypes were grouped in a highly distinct subpopulation when compared with European samples sharing the same mitochondrial barcodes. The reverse situation prevailed in Switzerland where bats carrying distinct barcodes had similar nuclear genotypes. There was a weak east/west nuclear structure of populations, but this was independent of mitochondrial lineages as bats carrying either variant were completely admixed. Thus, the divergent mitochondrial barcodes present in Western Europe do not represent cryptic species, but are part of a single biological species. We argue that these distinct barcodes evolved in allopatry and came recently into secondary contact in an area of admixture north of the Alps. Historical records from this area and molecular dating support such a recent bipolar spatial expansion. These results also highlight the need for using appropriate markers before claiming the existence of cryptic species based on highly divergent barcodes.

“…In M. punicus, both phenotypic similarity (Evin et al, 2008) and molecular phylogenetics (Castella et al, 2000) have demonstrated closer relationships between the Corsican and North African populations than between those populations and populations from other parts of the species' distribution. A North African origin has also been shown for P. pygmaeus (Hulva et al, 2010), whereas a European origin has been reported for P. kuhlii (Evin et al, 2011). In the case of P. pipistrellus, the Corsican population shows greater phenotypic similarity with the northern lineages of P. pipistrellus pipistrellus and P. pipistrellus aladdin than with the Moroccan lineage.…”

Aim The Mediterranean Basin is a centre of radiation for numerous species groups. To increase our understanding of the mechanisms underlying speciation and radiation events in this region, we assessed the phenotypic variability within the Pipistrellus pipistrellus-pygmaeus-hanaki species complex. Although bats form the second largest mammalian order, studies of insular evolution in this group are scarce. We approached this problem from a microevolutionary perspective and tested for the recurrence of the insular syndrome.Location The Mediterranean Basin, with a special focus on isolated populations from Corsica, the Maghreb, Cyprus, Cyrenaica and Crete.Methods Phenotypic variability was assessed by cranial morphometrics using the coordinates of 41 3D landmarks and associated geometric-morphometric methods. We analysed 125 specimens representing all of the lineages in the species complex. Differences between taxa and between insular and continental populations in cranial size, shape, form and allometries were tested using analyses of variance and visualized using boxplots and canonical variate analysis. Relationships between molecular data from a previous study (cytochrome b sequences) and morphometric data were tested with co-inertia analyses (RV test) and multivariate regressions. ResultsThe three species were relatively well differentiated in cranial size and shape, and each species showed a significant amount of inter-population variability. Comparisons of pairs of insular versus continental populations revealed heterogeneities in cranial patterns among island phenotypes, suggesting no recurrent insular syndrome. Molecular and phenotypic traits were correlated, except for molecular and lateral cranium shape. Main conclusionsThe Pipistrellus pipistrellus-pygmaeus-hanaki species complex exhibits phenotypic variability as a result of the fragmentation of its distribution (especially on islands), its phylogenetic and phylogeographic history and, most probably, other evolutionary factors that were not investigated in this study. We found no recurrent pattern of evolution on islands, indicating that sitespecific factors play a prevailing role on Mediterranean islands. The correlation between molecular and phenotypic data is incomplete, suggesting that factors other than phylogenetic relationships, potentially connected with feeding ecology, have played a role in shaping cranial morphology in this species complex.
