Data from: Latitudinal environmental niches and riverine barriers shaped the phylogeography of the central Chilean endemic Dioscorea humilis (Dioscoreaceae)Juan Viruel, Pilar Catalán & José Gabriel Segarra-Moragues
The effects of Pleistocene glaciations and geographical barriers on the phylogeographic patterns of lowland plant species in Mediterranean-climate areas of Central Chile are poorly understood. We used Dioscorea humilis (Dioscoreaceae), a dioecious geophyte extending 530 km from the Valparaíso to the Bío-Bío Regions, as a case study to disentangle the spatio-temporal evolution of populations in conjunction with latitudinal environmental changes since the Last Inter-Glacial (LIG) to the present. We used nuclear microsatellite loci, chloroplast (cpDNA)...
Data from: Walk the line: 600,000 years of molar evolution constrained by allometry in the fossil rodent Mimomys saviniCyril Firmat, Iván Lozano-Fernández, Jordi Agustí, Geir H. Bolstad, Gloria Cuenca-Bescós, Thomas F. Hansen & Christophe Pélabon
The allometric-constraint hypothesis states that evolutionary divergence of morphological traits is restricted by integrated growth regulation. In this study, we test this hypothesis on a time-calibrated and well-documented palaeontological sequence of dental measurements on the Pleistocene arvicoline rodent species Mimomys savini from the Iberian Peninsula. Based on 507 specimens representing nine populations regularly spaced over 600 000 years, we compare static (within-population) and evolutionary (among-population) allometric slopes between the width and the length of the...
Data from: \"Transcriptome sequence identity between Lyme disease tick vectors, Ixodes scapularis and Ixodes ricinus\" in Genomic Resources Notes accepted 1 April 2014 to 31 May 2014Marinela Contreras, Raquel Tobes, Libor Grubhoffer, Agustin Estrada-Peña & Jose De La Fuente
Ixodes scapularis and I. ricinus transmit the Lyme disease agent Borrelia burgdorferi in the U.S. and Europe, respectively. The only tick genome sequence available is that of I. scapularis, which constitutes a limitation for tick research. Recent evidences suggest that I. ricinus and I. scapularis transcriptomes share some degree of sequence identity. However, only the global transcriptome comparison reported here demonstrated that I. ricinus and I. scapularis share a 99.232±0.005 percent sequence identity with a...
Data from: Geometric morphometric analysis applied to theropod tracks from the lower Cretaceous (Berriasian) of SpainDiego Castanera, Jorge Colmenar, Victor Sauqué & José Ignacio Canudo
Geometric morphometric methods applied to theropod tracks from the Huérteles Formation (Berriasian, Spain) are here shown to be invaluable for drawing comparisons between theropod tracks with different preservation modes (true tracks, shallow undertracks and natural casts) or differing in the preservation of anatomical features (e.g. digital pads). Principal components analysis and thin-plate spline methods can quantitatively distinguish between the broad groups of tracks in a sample and establish the main differences between them. These methods...
