Anatomy of the nasal and auditory regions of the fossil lagomorph Palaeolagus haydeni: systematic and evolutionary implications
<p>Palaeolagus, a late Eocene to early Miocene North American lagomorph genus, represented by numerous and well-preserved specimens, has been long considered a basal leporid, although it is currently understood as a stem lagomorph. Based on micro-computed tomography (μCT) data and 3D reconstructions, here we present the first description of intracranial structures of the nasal and auditory regions of a complete skull of Palaeolagus haydeni from the early Oligocene of Nebraska. Although Palaeolagus haydeni shows a puzzling mixture of extant leporid and ochotonid characters, it helps to polarize and re-evaluate already known lagomorph intracranial characters based on outgroup comparison with Rodentia and Scandentia. Common derived features of Palaeolagus haydeni and extant Lagomorpha are the dendritic maxilloturbinal and the excavated nasoturbinal that contacts the lamina semicircularis. Generally, Palaeolagus haydeni and Leporidae have several characters in common, some of which are certainly plesiomorphic (e.g., thin wall of bulla tympani and flat conic cochlea). Palaeolagus haydeni resembles Leporidae in having an interturbinal between the two frontoturbinals, and three ethmoturbinals plus one interturbinal between ethmoturbinal I and II. Now, this should also be regarded as a plesiomorphic grundplan pattern for Leporidae whereas ochotonids are derived from the lagomorph grundplan as concerns the number of frontoturbinals. Concerning the middle ear, Palaeolagus haydeni significantly contributes to the polarization of the anterior anchoring of the malleus in extant lagomorphs. Palaeolagus haydeni resembles the pattern observed in early ontogenetic stages of Ochotonidae, i.e., the attachment of the malleus to the ectotympanic via a short processus anterior. The patterns in adult ochotonids and leporids now can be regarded as two different and apomorphic character states. Autapomorphic characters of Palaeolagus haydeni are the reduced frontoturbinal 2 and the additional anterolaterally oriented process of the lamina semicircularis. Interestingly, among the investigated intracranial structures the loss of the secondary crus commune is the only apomorphic grundplan character of crown Lagomorpha.</p> <p> </p>

Data from: The evolutionary history of the Cape hare (Lepus capensis sensu lato): insights for systematics and biogeography
Inferring the phylogeography of species with large distributions helps deciphering major diversification patterns that may occur in parallel across taxa. Here, we infer the evolutionary history of the Cape hare, <i>Lepus capensis sensu lato</i>, a species distributed from southern Africa to Asia, by analysing variation at 18 microsatellites and 9 DNA (1 mitochondrial and 8 nuclear) sequenced loci, from field and museum-collected samples. Using a combination of assignment and coalescent-based methods, we show that the Cape hare is composed of five evolutionary lineages, distributed in distinct biogeographic regions – north-western Africa, eastern Africa, southern Africa, the Near East and the Arabian Peninsula. A deep phylogenetic break possibly dating to the Early Pleistocene was inferred between the African and Asian <i>L. capensis</i> groups, and the latter appear more closely related to other Eurasian hare species than to African Cape hares. The inferred phylogeographic structure is shared by numerous taxa distributed across the studied range, suggesting that environmental changes, such as the progressive aridification of the Saharo-Arabian desert and the fluctuations of savannah habitats in Sub-Saharan Africa, had comparable impacts across species. Fine-scale analyses of the western Sahara-Sahel populations showed rich fragmentation patterns for mitochondrial DNA but not for microsatellites, compatible with the environmental heterogeneity of the region and female philopatry. The complex evolutionary history of <i>L. capensis sensu lato</i>, which possibly includes interspecific gene flow, is not reflected by taxonomy. Integrating evolutionary inference contributes to an improved characterization of biodiversity, which is fundamental to foster the conservation of relevant evolutionary units.
