Abstract: Aim: to understand the role of climate in fostering
diversification, this study reconstructs the historical biogeography of
Western Mediterranean vipers Location: Western Mediterranean Basin Taxon:
Vipera aspis and V. latastei-monticola complex Methods: phylogeographic
analyses were performed over mitochondrial (three genes) and nuclear
sequences (two genes), extensively covering species ranges. A total of
4,056 records were assigned to genetic units, using interpolations of
genetic data, to test phylogenetic niche conservatism, under a 3D
hypervolume approach, and to perform paleoclimatic reconstructions for
main lineages that diversified during the Pleistocene. Results: Bayesian
inferences based on mtDNA recovered three Miocene clades and nine Pliocene
lineages that distinctly diversified during the Pleistocene.
Diversification until late Pliocene was mostly restricted to southern
regions of Iberian and Italian Peninsulas, and north-western African
mountains, expanding northwards during the Pleistocene. Accordingly,
genetic diversity was higher in southern regions. Ecological niche tests
support a general mode of allopatric diversification with niche
conservatism, although niche shift was found for two divergence events.
Paleoclimatic models identified particular requirements for the
distribution of main lineages and distinct responses to the cooling and
warm events of the Pleistocene. Areas of climatic stability during
Pleistocene were identified for main lineages; however, climatic stability
was weakly correlated to haplotype diversity. Main conclusions: our
integrative approach enhances the understanding of the evolutionary and
ecological dynamics occurred in the Western Mediterranean region,
evidencing the paleo-tectonic and -climatic factors driving
diversification since the Miocene in this biodiversity hotspot.
Comparisons among patterns of diversification, haplotype diversity and
climatic stability suggest that southern Iberian and Italian Peninsulas,
and North-West African Mountains acted as refugia since the Pliocene,
while some northern areas favoured population persistence during the
Pleistocene.
Alignments of sequences (in fasta format) for 5 markers, 3 mithocondrial
(cytochrome b, Cytb; and NADH dehydrogenase subunits 2, ND2, and 4, ND4)
and 2 nuclear (prolactin receptor, PRLR; Neurotoxin-3, NT3). Sequences,
and data for each one, are available on GenBank. Occurrence data for V.
aspis (VAS), V. latastei in Iberian Peninsula (VLA_Iberia) and V. latastei
in North Africa [V. monticola included] (VLA_North-Africa). Data were
retrieved from fieldwork, museum collections, publications and
herpetological societies’ databases (including AHE, Spain; SHF, France;
info fauna - karch, Switzerland). Occurrence data were processed at 5x5 km
resolution in WGS84.
