A ustralia, which lies southeast of Asia between the Indian and Pacific oceans, consists of the smallest continent (and the world’s largest island—approximately 4,000 km from east to west and 2,000 km from north to south) as well as the island of Tasmania. About a third of the continent is uninhabitable; in another third the rainfall is too low to permit close settlement. The climate varies fro...

This report provides a brief review of key findings related to frost resistance in alpine woody plant species, summarizes data on their frost resistance, highlights the importance of freeze avoidance mechanisms, and indicates areas of future research. Freezing temperatures are possible throughout the whole growing period in the alpine life zone. Frost severity, comprised of both intensity and d...
The crystalline basement of New Zealand shows a chi-shaped combination of the straight Alpine Fault and a curved late Paleozoic continental margin, so that the plutonic basement of northern Fiordland converges toward the plane of the Alpine Fault. On the ground along Milford Sound the petrography suggests (1) a gradual change from amphibolite and granulite fades in the west to igneous fabrics d...
The major histocompatibility complex (MHC) is a crucial component of the vertebrate immune system and shows extremely high levels of genetic polymorphism. The extraordinary genetic variation is thought to be ancient polymorphisms maintained by balancing selection. However, introgression from related species was recently proposed as an additional mechanism. Here we provide evidence for introgres...
