NERC MSTRF Sky-Camera Time-Lapse Video for 2010-09-07 05:30 UTC (showing widespread development of Cumulonimbus clouds, some of which have extensive Anvils).
<p>A time-lapse video showing widespread development of Cumulonimbus clouds, some of which have extensive Anvils. A variety of other cumuloform clouds can be seen. The origin of the widespread cirrus cloud seen during the second half of the sequence is probably outflow from Cumulonimbus anvils. This video has been created from images taken by the NERC MST Radar Facility's Sky-Camera, which is located near Aberystwyth in West Wales.

Genetic evidence for widespread population size expansion in North American boreal birds prior to the Last Glacial Maximum
<p>Pleistocene climate cycles are well known to have shaped contemporary species distributions and genetic diversity. Northward range expansions in response to deglaciation following the Last Glacial Maximum (LGM; ~21,000 years ago) have been surmised to lead to population size expansions in terrestrial taxa and changes in seasonal migratory behaviour. Recent findings, however, suggest that some northern temperate populations may have been more stable than expected through the LGM. We modelled the demographic history of twenty co-distributed boreal-breeding bird species of North America from full mitochondrial gene sets and species-specific molecular rates. We used these demographic reconstructions to test how species with different migratory strategies were affected by glacial cycles. Our results suggest that effective population sizes increased in response to deglaciation during the middle Wisconsin period (~45,000 years ago) whereas genetic diversity was maintained throughout the LGM despite shifts in geographic range. We conclude that earlier glacial cycles prior to the LGM have most strongly shaped contemporary genetic diversity in these high-latitude species. We did not find differences in historic population dynamics between species differing in migratory behaviour, contributing to growing evidence that major switches in migratory strategy during the Last Glacial Maximum are unnecessary to explain contemporary migratory patterns.</p>

Widespread reticulate evolution in an adaptive radiation
<p>A fundamental assumption of evolutionary biology is that phylogeny follows a bifurcating process. However, hybrid speciation and introgression are becoming more widely documented in many groups. Hybrid inference studies have been historically limited to small sets of taxa, while exploration of the prevalence and trends of reticulation at deep time scales remains unexplored. We study the evolutionary history of an adaptive radiation of 109 gemsnakes in Madagascar (Pseudoxyrhophiinae) to identify potential instances of introgression. Using several network inference methods, we find twelve reticulation events within the 22-million-year evolutionary history of gemsnakes, producing 28% of the diversity for the group, including one reticulation that resulted in the diversification of an 18 species radiation. These reticulations occur at nodes with high gene tree discordance. Hybridization events occurred between north-south distributed parentals that share similar ecologies. Younger hybrids occupy intermediate contact zones between the parentals, showing that post-speciation dispersal in this group has not eroded the spatial signatures of introgression. Reticulations accumulated consistently over time, despite drops in overall speciation rates during the Pleistocene. This suggests that while bifurcating speciation may decline as the result of species accumulation and environmental change, speciation by hybridization may be more robust to these processes.</p>
