Winter bugs called snow fleas are born in icy waters and feed on algae that grows on snow. Spring-tails are also called snow fleas and they leap around on snow banks. They eat the sap which oozes from trees. Spring-tails look very similar to fossils of 300 million years ago!
Survival of the weakest
Survival of the weakest Scientists have released the results of a study
which suggests that the small amount of seeds produced by plants
located in the rainforest is the source of the huge diversity of
life found in tropical rainforests. The report suggests that gaps
in the forest are being occupied at random, by whatever seed
happens to be there at the time. This is possible because plants in
any given area do not produce enough seeds to fill that area up
with offspring. This strategy not only gives weaker species a
chance to germinate, but also promotes a high level amount of
diversity even in a small area. 30 JANUARY 1999, P. 15
