“…However, another major event that led to the disappearance of O. valdarnensis from the Italian fossil record around 1.2 Ma may correspond to the maximum cold peak of MIS 36 (Joannin 2007, Altolaguirre et al . 2019). This event was marked by a general change in the composition of forests and a major renewal of the mammal community in Europe (Head & Gibbard 2005; Magri & Palombo 2013).…”

The early Pleistocene is the key period for understanding the evolutionary history and palaeobiogeography of rabbits (Genus Oryctolagus). In western Europe, many species were endemic, making them a reliable indicator of the evolution of the terrestrial ecosystems in which many species have evolved. However, the morphological variability of rabbit species is still poorly understood and their phylogeny remains a subject of debate. Through both qualitative (morphological description) and quantitative (linear measurements and two‐dimensional geometric morphometrics) approaches, we address here the morphometric diversity of the third lower premolar (p3), a tooth commonly used to distinguish leporid species, in order to assess intra‐ and inter‐regional morphological variations in several early Pleistocene rabbit populations. Our results suggest that the different approaches are complementary and allow, on different levels, a full characterization of the p3 variability of early Pleistocene rabbits and to imply relations between populations. The size and shape variations of this tooth reflect the taxonomic and phylogenetic signals of the different species but were probably also significantly impacted by geographical position and local climatic conditions. In view of the great morphometric variability highlighted in this work, we suggest a careful reconsideration of certain dental criteria previously considered ‘diagnostic’ in the characterization of these species. However, the overall results allowed us to discuss the phylogeny of the genus Oryctolagus and to hypothesize the ecological requirements and different phases of the dispersal of taxa in western Europe, probably associated with global climate changes.

“…The transition between Pliocene and Pleistocene is well known for the abrupt climate change causing the onset of the major northern hemisphere glaciations at approximately 2.7 Ma (Lisiecki and Raymo, 2005). Also in the Iberian Peninsula, a cyclic climate regime with warm and humid interglacials and cold and dry glacials established during the early Pleistocene (Altolaguirre et al, 2019). The onset of glacial-interglacial oscillations might have produced latitudinal and elevational species-range shifts that brought into contact the once isolated Leucanthemopsis lineages.…”

Polyploidization is one of the most common speciation mechanisms in plants. This is particularly relevant in high mountain environments and/or in areas heavily affected by climatic oscillations. Although the role of polyploidy and the temporal and geographical frameworks of polyploidization have been intensively investigated in the alpine regions of the temperate and arctic biomes, fewer studies are available with a specific focus on the Mediterranean region. Leucanthemopsis (Asteraceae) consists of six to ten species with several infraspecific entities, mainly distributed in the western Mediterranean Basin. It is a polyploid complex including montane, subalpine, and strictly alpine lineages, which are locally distributed in different mountain ranges of Western Europe and North Africa. We used a mixed approach including Sanger sequencing and (Roche-454) high throughput sequencing of amplicons to gather information from single-copy nuclear markers and plastid regions. Nuclear regions were carefully tested for recombinants/PCR artifacts and for paralogy. Coalescent-based methods were used to infer the number of polyploidization events and the age of formation of polyploid lineages, and to reconstruct the reticulate evolution of the genus. Whereas the polyploids within the widespread Leucanthemopsis alpina are autopolyploids, the situation is more complex among the taxa endemic to the western Mediterranean. While the hexaploid, L. longipectinata, confined to the northern Moroccan mountain ranges (north–west Africa), is an autopolyploid, the Iberian polyploids are clearly of allopolyploid origins. At least two different polyploidization events gave rise to L. spathulifolia and to all other tetraploid Iberian taxa, respectively. The formation of the Iberian allopolyploids took place in the early Pleistocene and was probably caused by latitudinal and elevational range shifts that brought into contact previously isolated Leucanthemopsis lineages. Our study thus highlights the importance of the Pleistocene climatic oscillations and connected polyploidization events for the high plant diversity in the Mediterranean Basin.

“…They also reveal that the oscillations in precipitation recorded between the "interglacial" and "glacial" phases were not extreme, which could have facilitated the development of mosaic environments in the glacial phases of the Iberian Peninsula. In short, Altolaguirre et al (2019Altolaguirre et al ( , 2020 suggest that there were long warm, humid periods, interspersed with short periods of a more temperate and above all drier climate, visible in particular in the Upper and Lower Sections of Palominas, whereas in the Middle Section of Palominas the climate was cooler and humid during interglacials (Altolaguirre et al, 2020: fig. 8).…”
