The Mesozoic Lacustrine Revolution

The Mesozoic lacustrine revolution (MLR) represents a major evolutionary event in the continental realm (Cohen 2003 ). The decline in taxic diversity at the family level in lacustrine environments that took place during the late Paleozoic–Middle Triassic was reversed later in the Mesozoic, with diversifi cation seeming to have continued to the Quaternary, although potential biases may have affe...

Bird Radiations

ed landscape with relatively few native birds. Its original host remains unknown, but unlike many islands, New Zealand had endemic mosquitoes, which could have coevolved with viruses. Another signifi cant disease because of its pandemic potential is avian infl uenza. The normal hosts are waterfowl, shorebirds, and seabirds. Sampling for infl uenza antibodies in Australian seabirds shows variati...

Delimiting species in recent radiations.

Despite considerable effort from the systematics community, delimiting species boundaries in recent radiations remains a daunting challenge. We argue that genealogical approaches, although sometimes useful, may not solve this important problem, because recently derived species often have not had sufficient time to achieve monophyly. Instead, we suggest that population genetic approaches that re...
