The repeated evolution of phenotypes provides clear evidence for the role of natural selection in driving evolutionary change. However, the evolutionary origin of repeated phenotypes can be difficult to disentangle as it can arise from a combination of factors such as gene flow, shared ancestral polymorphisms or mutation. Here, we investigate the presence of these evolutionary processes in the Hawaiian spiny‐leg Tetragnatha ad...

Recent phylogeographic studies have elucidated the effects of Pleistocene glaciations and of Pre‐Pleistocene events on populations from glacial refuge areas. This study investigates those effects in riparian trees ( Populus spp.), whose particular features may convey enhanced resistance to climate fluctuations. We analysed the phylogeographic structure of 44 white ( Populus alba ), 13 black ( Populus nigra ) and two grey ( Pop...

We generated a genomic DNA library for Nothofagus solandri using 454 sequencing. Sequences from this library were screened for simple sequence repeat (microsatellite) motifs. Polymerase chain reaction (PCR) primer pairs were designed for 44 candidates and tested on a selection of samples collected from the wild. Seven of these PCR primer combinations produced interpretable polymorphic products. These have been assayed in 176 p...
