We investigated the effects of Ni concentration on hydrogen (H 2 ) net production and nitrogen (N 2 ) fixation rates in a model unicellular diazotrophic cyanobacterium, Cyanothece . We quantified NiFe uptake hydrogenase of the diazotroph to examine how Ni deficiency affects the expression of hydrogenase and nitrogenase and N 2 fixation rates. We found that Ni availability controls its H 2 net production and the expression of H...

Typhoon Morakot (2009), which made landfall in Taiwan during August 7–9, 2009, produced the highest rainfall and became the deadliest typhoon ever recorded in Taiwan since 1958. To assess the role of anthropogenic climate change in the typhoon‐related torrent, we compare the water budget between a pair of cloud‐resolving sensitivity experiments. The pair consists of a control simulation that reproduces Typhoon Morakot (2009) i...
