Leaf mold is not high in nutrient content but is an excellent humic soil conditioner because its structure and moisture retention provide a good growing medium for seedling roots. Leaves collected from roads and pavements may be contaminated by pollutants which can become more concentrated as the leaves decompose into a smaller volume [ 11 ]
At night, transpiration usually does not occur, because most plants have their stomata closed. When there is a high soil moisture level, water will enter plant roots, because the water potential of the roots is lower than in the soil solution. The water will accumulate in the plant, creating a slight root pressure.
In artificial environments such as buildings, humidity and temperature are often stable enough to foster the growth of mold colonies, commonly seen as a downy or furry coating growing on food or other surfaces. Few molds can begin growing at temperatures of 4 °C (39 °F) or below, so food is typically refrigerated at this temperature. When ...
Spores need three things to grow into mold: nutrients – cellulose (the cell wall of green plants) is a common food for indoor spores; moisture – to begin the decaying process caused by mold; and time – mold growth begins from 24 hours to 10 days after the provision of growing conditions. Mold colonies can grow inside buildings, and the ...
A mildew-infected plant. There are many species of mold. The black mold which grows in attics, on window sills, and other places where moisture levels are moderate often is Cladosporium. Colour alone is not always a reliable indicator of the species of mold. Proper identification requires a microbiologist or mycologist.

Cladosporium cladosporioides is a common saprotroph occurring as a secondary infection on decaying, or necrotic, parts of plants. [6] This fungus is xerophilic – growing well in low water activity environments (e.g., a W = 0.86–0.88). [14] This species is also psychrophilic, it can grow at temperatures between −10 and −3 °C (14 and 27 ...
During extreme cold events, you may hear a loud boom and feel like you have experienced an earthquake. However, this event was more likely a cryoseism, also known as an ice quake or a frost quake ...
