Speciation with gene flow on Lord Howe Island.
Understanding the processes underlying the origin of species is a fundamental goal of biology. It is widely accepted that speciation requires an interruption of gene flow between populations: ongoing gene exchange is considered a major hindrance to population divergence and, ultimately, to the evolution of new species. Where a geographic barrier to reproductive isolation is lacking, a biologica...
متن کاملReassembling island ecosystems: the case of Lord Howe Island
Exotic species that invade remote islands, usually following human settlement, have had catastrophic effects on native biota. However, on islands it is increasingly feasible to eradicate key exotic species allowing extant native species to recover in situ or to return naturally. The practice of marooning threatened species on islands where the threat is absent, irrespective of whether the threa...
متن کاملLord Howe Island, A Riddle of the Pacific, Part III
Our knowledge of the insects of Lord Howe Island is only preliminary and incomplete. Some groups, for example but terflies and beetles, are more or less sufficien tly studi ed, other groups very poorly. Descriptions of new endemic species and records of the insects of the island are dispersed in many articles, and a summary of our knowledge in this regard is lacking. However, a high endemism of...
متن کاملSynopsis of the hymenopteran fauna of Lord Howe Island with a preliminary checklist of species.
Lord Howe Island is an eroded remnant of a shield volcano approximately 600 km northeast of Sydney, New South Wales, Australia. It has fascinated biologists for more than a century because of its unique and iconic fauna and flora, and was declared a World Heritage Site in 1982. Although the terrestrial invertebrate fauna is reasonably well known for many groups, most Hymenoptera, apart from ant...
متن کاملRodent eradication on Lord Howe Island: challenges posed by people, livestock, and threatened endemics
Like many oceanic islands, World Heritage listed Lord Howe Island (LHI), 760 km north-east of Sydney (Australia), has populations of invasive rodents. The house mouse (Mus musculus) probably arrived around 1860, and the ship rat (Rattus rattus) in 1918. Both species have significantly reduced the island’s biodiversity. Rats are implicated in the extinction of at least 20 species (or subspecies)...
