Water hyacinth is a common fodder plant in the third world especially Africa though excessive use can be toxic. It is high in protein (nitrogen) and trace minerals and the goat feces are a good source of fertilizer as well. Water hyacinth is reported for its efficiency to remove about 60–80% nitrogen [123] and about 69% of potassium from ...
Early- to mid-spring blooming hyacinths (Hyacinthus spp.) are available in shades of blue, pink, red, purple, and white. Sweet-scented and hardy in the same climate as snowdrops, they make a ...
Insects that live under the water have different strategies for dealing with freezing than terrestrial insects do. Many insect species survive winter not as adults on land, but as larvae underneath the surface of the water. Under the water many benthic invertebrates will experience some subfreezing temperatures, especially in small streams.
Cold hardening has also been observed in insects such as the fruit fly and diamondback moth. These insects use rapid cold hardening to protect against cold shock during overwintering periods. [5] [6] Overwintering insects remain active through the winter while non-overwintering insects migrate or die. Rapid cold hardening can occur during short ...

Vernalization (from Latin vernus 'of the spring') is the induction of a plant's flowering process by exposure to the prolonged cold of winter, or by an artificial equivalent. After vernalization, plants have acquired the ability to flower, but they may require additional seasonal cues or weeks of growth before they will actually do so.
Plants have evolved numerous strategies to deal with cold air, frozen soil, and in the coldest of conditions, lack of water through the winter. Brr! Here are 4 ways plants, trees survive frigid ...
