Although many large mammal species went extinct at the end of the Pleistocene epoch, their DNA may persist due to past episodes of interspecies admixture. However, direct empirical evidence of the persistence of ancient alleles remains scarce. Here, we present multifold coverage genomic data from four Late Pleistocene cave bears (Ursus spelaeus complex) and show that cave bears hybridized with brown bears (Ursus arctos) during the Pleistocene. We develop an approach to assess both the...

Data from: Arachnid aloft: directed aerial descent in neotropical canopy spiders

Stephen P Yanoviak, Yonatan Munk & Robert Dudley
The behaviour of directed aerial descent has been described for numerous taxa of wingless hexapods as they fall from the tropical rainforest canopy, but is not known in other terrestrial arthropods. Here, we describe similar controlled aerial behaviours for large arboreal spiders in the genus Selenops (Selenopidae). We dropped 59 such spiders from either canopy platforms or tree crowns in Panama and Peru; the majority (93%) directed their aerial trajectories towards and then landed upon...

In Situ Transmission Electron Microscopy Data of Dislocations in Imperfectly Attached PbTe Nanocrystal Pairs

Justin Ondry, Matthew Hauwiller & A. Paul Alivisatos
Dataset containing high resolution transmission electron microscopy data of imperfectly attached PbTe nanocrystals. The data contains High Resolution TEM timeseries of images showing the annealing of of well defined b=a/2[110] edge dislocations in PbTe nanocrystal pairs viewed down the<001> zone axis. Depending on the attachment facets of the particles, the dislocations anneal out at different rates. In addition we performed geometric phase analysis on the images to visualize the strain fields surrounding the dislocation cores....
