Extremes of precipitation are examined in a wide range of climates simulated with an idealized aquaplanet GCM. The high percentiles of daily precipitation increase as the climate warms. Their fractional rate of increase with global-mean surface temperature is generally similar to or greater than that of mean precipitation, but it is less than that of atmospheric (column) water vapor content. A ...

Pressure and temperature are important environmental variables that influence living systems. However, while they vary over a considerable range on Earth and other planets, it has hardly been addressed how straightforwardly and to what extent cellular life can acquire resistance to extremes of these parameters within a defined genomic context and a limited number of generations. Nevertheless, t...

Phytophthora ramorum Werres, De Cock & Man in ‘t Veld, a recent introduction into the United States, has proven to be a threat to hardwood forests on the west coast, specifically tanoak (Lithocarpus densiflorus (Hook & Arn.) Rehder) and Quercus spp. (34). This pathogen has a broad host range which is ever-expanding and includes understory plants and commonly grown nursery plants (19,25). Some n...
