Links for 2006-12-09
- A NAS "bridge" board. (thanks to Colin McCormack for the link)
- Kosciuszko Park's centenary. (Intriguing: the ABC and the Park's Plan of Management disagree about the size of Snowy Mountains National Chase; 160 vs. 300 square km. Unfortunately the 1906 Gazette is not available online.)
- An adjustment on the earlier linked Complex life on Earth may have been spawned by an ecological disaster ~250 million years ago. I missed the discrepancy between the article's heading (disaster "spawned" complex life) and its body (disaster increased the "proliferation" of complex life, upping the complex:simple ratio (on what scale?) from 1:1 to 3:1). A loosely related article by the same author speculates that the end of a glaciation ~550 million years ago led to a boom in phytoplankton, which oxygenated the air and thus the water, which made way for more complex life (hard shells, mobility, ...) to arise in the first place.
