Summary To prevent indoor fungal growth, understanding the moisture relations of fungi is a key element. Indoor moisture is quantified by the relative humidity ( RH ). RH controls the water activity of the indoor materials that fungi grow on, a well‐studied parameter known to limit fungal growth. RH , however, also controls the amount of water present in these materials, the moisture content. The significance of the moisture c...

A bstract Kelp gulls at Península Valdés, Argentina, have recently developed the habit of feeding on pieces of skin and blubber that they gouge from the backs of southern right whales. In response, the whales flinch violently, submerge, and swim rapidly away underwater. The level of harassment in 1995 was almost five times higher than when first studied in 1984 by Thomas (1988). In 1995, 67% of attacks were aimed at large whit...
