Precision measurement of the Ds*+-Ds+ meson mass differenceNARA Subscribed
Billfish rostra potentially have several functions; however, their role in feeding is unequivocal in some species. Recent work linked morphological variation in rostral micro‐teeth to differences in feeding behavior in two billfish species, the striped marlin ( Kajikia audax ) and the sailfish ( Istiophorus platypterus ). Here, we present the rostral micro‐tooth morphology for a third billfish species, the blue marlin ( Makair...
Lacunae rostralis: A new structure on the rostrum of sailfish Istiophorus platypterusNARA Subscribed
Recent comparative studies of billfishes (Istiophoridae and Xiphiidae) have provided evidence of differences in the form and function of the rostra (bill) among species. Here, we report the discovery of a new structure, lacuna rostralis, on the rostra of sailfish Istiophorus platypterus , which is absent on the rostra of swordfish Xiphias gladius , striped marlin Kajikia audax and blue marlin Makaira nigricans . The lacunae ro...
Timing and tempo of evolutionary diversification in a biodiversity hotspot: Primulaceae on Indian Ocean islandsNARA Subscribed
Aim We examined phylogenetic relationships and spatio‐temporal diversification in Indian Ocean Primulaceae, assessing correlations between speciation rates, geographical expansion and ecomorphological specialization. Location Madagascar and Indian Ocean Islands. Methods We conducted phylogenetic analyses with plastid and nuclear DNA sequences of Primulaceae using maximum likelihood and Bayesian algorithms, and estimated diverg...
Analysis of molecular data of Arabidopsis thaliana (L.) Heynh. (Brassicaceae) with Geographical Information Systems (GIS)NARA Subscribed
A Geographical Information System (GIS) is used to analyse allelic information of 13 sequenced loci of natural populations of Arabidopsis thaliana and to identify geographical structures. GIS provides tools for visualization and analysis of geographical population structures using molecular data. The geographical distribution of the number of variable positions in the alignments, the distribution of recombinant sequence blocks...
