Monophyly and transoceanic dispersal in the widespread floating club-rush clade, Isolepis subgenus Fluitantes (Cyperaceae) by Jan-Adriaan Viljoen, Terry Hedderson, Charlotte Sletten Bjorå, Muthama Muasya

“…Australasia was colonised by a single long-distance dispersal event ca 3 mya. Incongruence between the plastid and nuclear gene trees was apparent for the Australasian taxa, I. crassiuscula, I. lenticularis, and I. producta, with their atpI&amp;ndash;H sequences placing them with I. ludwigii in the Fluitantes and the ITS nrDNA resolving them in the Proliferae. …”

Trypanosoma cruzi -- the vector-parasite paradox by CJ Schofield

“…But while recent molecular studies indicate a relatively ancient origin for the parasite (~65 million years ago) there is increasing evidence that the blood-sucking triatomine vectors have evolved comparatively recently (<5 mya). This review examines the evidence for these ideas, and attempts to reconcile the apparent paradox by suggesting that marsupial opossums (Didelphidae) may have played a role, not just as original reservoir hosts, but also as original vectors of the parasite.…”
