Decadal samples of dendrochronologically dated pine (Lagorostrobos franklinii) from the Stanley River basin, Tasmania, have been radiocarbon dated between 2120–850 yr BP. This data set overlaps and extends the current Southern Hemisphere record, which covers the period 110–995 yr BP. There is good agreement between the 2 records between 995– 850 yr BP, between sample replicates and with consens...

The Southern Hemisphere has traditionally been considered as having a fundamentally vicariant history. The common trans-Pacific disjunctions are usually explained by the sequential breakup of the supercontinent Gondwana during the last 165 million years, causing successive division of an ancestral biota. However, recent biogeographic studies, based on molecular estimates and more accurate paleo...

Sunspot drawings are provided on a regular basis at the Kanzelhöhe Solar Observatory, Austria, and the derived relative sunspot numbers are reported to the Sunspot Index Data Center in Brussels. From the daily sunspot drawings, we derived the northern, Rn, and southern, Rs, relative sunspot numbers for the time span 1975– 2000. In order to accord with the International Sunspot Numbers Ri, the R...

BACKGROUND To assess quarterly fluctuations in schizophrenia births in a southern hemisphere data set, and to compare the quarterly birth distributions of patients born in the northern and southern hemisphere. METHOD The month and place of birth of patients with schizophrenia (n = 9348) were extracted from a mental health register. RESULTS The quarterly birth distribution of patients with s...
